Removable partial dentures: Part 3.

The provision of removable partial dentures (RPDs) is an important skill for practitioners and it can often be challenging to make a successful prosthesis which the patient finds satisfactory. This three-part series has been designed to provide an overview of the clinical management of patients requiring RPDs. This final part describes more complex techniques that may be faced by dentists with additional training or experience in fixed and removable prosthodontics. These scenarios include the use of precision attachments to provide additional retention for an RPD, swinglock dentures to aid retention in cases with unfavourable tooth or alveolar undercuts, and sectional dentures for patients with challenging paths of insertion. For each clinical technique, the advantages, disadvantages and indications are summarised.

Clinical Applications of Intraoral Scanning in Removable Prosthodontics: A Narrative Review

In Vitro Analysis of Bonding and Wear Properties of 3D Printed Denture Tooth Materials.

While additive manufacturing (3D printing) has recently enhanced removable prosthodontics, the properties of new 3D printed materials are not well understood. This study aims to elucidate the physical properties of these materials, focusing on bonding to a 3D printed denture base material and wear resistance. For denture tooth-denture base bonding analyses, the same denture tooth material (Premium Teeth, Formlabs) was used with three denture base-bonding group assignments (n=6 each group) bonded using three protocols: Group A1 was bonded with Lucitone Digital Print-3D Denture Base using the Lucitone Fuse System (Dentsply), Group A2 with Formlabs Denture Base using the Formlabs Denture Base Bonding System, and Group A3 with Formlabs Denture Base using the Ivoclar Ivotion Bonding System (Ivoclar). Specimens were made according to the ISO-TS-19736-2027 standard. A 3D printed tooth mimicking a central incisor was bonded to the denture base and subjected to a palatal load at the incisal region at 90° from the long axis of the tooth until failure. The fracture surface was examined at 10× magnification. ANOVA with α=0.05 was used to determine statistically significant differences. For wear analysis, the same denture base material and bonding system (Lucitone Digital Print-3D Denture Base/Lucitone Fuse System, Dentsply) was used with four denture tooth material group assignments (n=8 each group): Group B1 used Formlabs Premium Teeth, Group B2 used SprintRay High Impact Denture Teeth, Group B3 used Lucitone Digital IPN Premium Tooth, and Group B4 used Ivotion Polymethyl Methacrylate (PMMA) Milled Teeth (Ivoclar). A premolar denture tooth bonded with the denture base was subjected to a chewing simulation cyclic loading of 1,200,000 cycles. Sample failures, vertical wear, and volume loss were documented. ANOVA with α=0.05 was used to determine statistically significant differences. The fracture load to failure values for A1, A2, and A3 were 175±106 N, 167±46.3 N, and 183±48.9 N, respectively (p=0.95). Most failure characteristics were mixed, except one of A2 was cohesive and half of A3 was cohesive. For cyclic loading, B4 was the only group where all specimens failed within 1,200,000 cycles, while B1, B2, and B3 had four, three, and five sample failures, respectively. Vertical wear was 0.93±0.34 mm, 1.22±0.37 mm, 1.05±0.27 mm, and 0.37±0.02 mm for B1, B2, B3, and B4, respectively (p<0.01). Abrasion volumes were 9.5±3.7 mm³, 12.2±4.7 mm³, 10.6±3.5 mm³, and 2.2±1.3 mm³ for B1, B2, B3, and B4, respectively. Vertical height loss per chewing cycle (μm/cycle) was 0.0022±0.0019, 0.0030±0.0029, 0.0012±0.00005, and 0.0080±0.0050 for B1, B2, B3, and B4, respectively (p<0.01). Abrasion volume per chewing cycle (μm³/cycle) was 17650.8±9682.9, 27263.4±24746.8, 11836.5±4200.8, and 70436.8±73602.5 for B1, B2, B3, and B4, respectively (p=0.02). The bonding strength and wear resistance of 3D printed denture materials vary by manufacturer. Formlabs Denture Base with Ivoclar Ivotion showed the highest fracture load, indicating superior bonding strength. In wear analysis, Ivoclar Ivotion PMMA Milled Teeth exhibited the least vertical wear and abrasion volume but had the highest failure rate under cyclic loading. While printed denture materials excel in bonding strength, their wear resistance may not be as good as milled denture teeth, highlighting the need to balance these properties in clinical applications.

Learning from Mistakes—Dental Students’ Learning Experiences from Adverse Clinical Events

Clinical training in the teaching practice is essential for developing patient-specific skills, yet the transition from preclinical to clinical training presents significant challenges for students. This study aimed to comprehend the challenges and issues faced by students at the onset of clinical training. It retrospectively investigated adverse events presented at the advanced dentistry course by third-year pre-doctoral students from classes 202A, 202B, and 202C during their initial ten months of clinical practice at the teaching institution. In this study, adverse events were defined as any undesirable experiences or incidents associated with a clinical treatment and administrative procedures. A total of 279 adverse events presented were categorized into eight disciplines: Treatment planning (TP), Operative (OP), Periodontics (PER), Endodontics (EN), Oral Surgery (OS), Fixed Prosthodontics (FP), Removable Prosthodontics (RP), and Patient Management (PM). The distribution of events was as follows: TP (11.5%), OP (17.7%), PER (13.1%), EN (6.9%), OS (6.2%), FP (24.2%), RP (5.0%), and PM (15.4%), with FP, OP and PM experiencing the highest rates of adverse events. The distribution pattern within the disciplines was consistent, and no statistical difference was observed. Across these disciplines, a lack of clinical skill competency was identified as a primary cause of adverse events. Other contributing issues included miscommunication, insufficient explanations to patients, a lack of administrative support, case complexity, and a deficit in diagnostic examinations and skills. The frequency of causes varied across the three classes, but no significant differences was noted in OP, FP and OS, in which over 80% of causes were related to clinical skill competency. Adverse events in clinical settings are frequent. Knowing these beforehand can aid students’ performance. Students should prepare thoroughly before clinical practice and understand common causes of errors. Educators should recognize the challenges inexperienced students encounter. Awareness of typical mistakes can enhance success in demanding clinical scenarios.

Self-reported preparedness of final year undergraduate dental students and interns in Saudi Arabia: a multi-institutional study

BackgroundContemporary undergraduate dental education aims to equip the dental students with clinical competence, empathy, and professionalism to enable them to deliver safe and effective dental care to the communities. The purpose of this study was to assess the self-reported preparedness of final year dental students and interns at three Saudi dental institutions, using the pre-validated Dental Undergraduates Preparedness Assessment Scale (DU-PAS).MethodsA cross-sectional study design was employed to assess the self-reported preparedness of the participants using the DU-PAS. Following ethics approval, a probability sampling technique was used to recruit undergraduate dental students and interns from three dental institutions in Saudi Arabia. The data was collected online on Google Forms and all participants provided their consent to participate in the study prior to providing their responses to DU-PAS.ResultsResponses were received from 397 participants including 171 males and 226 females yielding a response rate of 60.3%. The total mean score of the participants was 81.85 ± 13.11. Although higher scores were reported in males, the interaction between gender and DU-PAS scores were not significant. Interaction between DU-PAS scores and stage of education showed significant effect of the stage of education with interns reporting higher overall scores. The participants reported that they were able to perform most clinical procedures independently. However, low confidence was reported in performing multi-rooted endodontics, fabrication of removable dentures and orthodontic assessment. The participants also expressed their confidence in a wide range of behavioural attributes related to communication, teamworking and professionalism. However, lack of experience was noted in referral for oral cancer, interpreting research, and evaluation of new dental products using an evidence-based approach.ConclusionThe study provides useful insights into the self-reported preparedness of undergraduate dental students and interns in three dental institutions. While the overall preparedness of the participants was comparable to their international peers, the findings underscore the need for further enhancements to the teaching and training of undergraduate students particularly in multirooted endodontics, removable prosthodontics and orthodontics.

An assessment of preclinical removable prosthodontics based on multiple-choice questions: Stakeholders' perceptions.

Item analysis of multiple-choice questions (MCQs) is an essential tool for identifying items that can be stored, revised, or discarded to build a quality MCQ bank. This study analyzed MCQs based on item analysis to develop a pool of valid and reliable itemsand investigate stakeholders' perceptions regarding MCQs in a written summative assessment (WSA) based on this item analysis. In this descriptive study, 55 questions each from 2016 to 2019 of WSA in preclinical removable prosthodontics for fourth-year undergraduate dentistry students were analyzed for item analysis. Items were categorized according to their difficulty index (DIF I) and discrimination index (DI). Students (2021-2022) were assessed using this question bank. Students' perceptions of and feedback from faculty members concerning this assessment were collected using a questionnaire with a five-point Likert scale. Of 220 items when both indices (DIF I and DI) were combined, 144 (65.5%) were retained in the question bank, 66 (30%) required revision before incorporation into the question bank, and only 10 (4.5%) were discarded. The mean DIF I and DI values were 69% (standard deviation [Std.Dev] = 19) and 0.22 (Std.Dev = 0.16), respectively, for 220 MCQs. The mean scores from the questionnaire for students and feedback from faculty members ranged from 3.50 to 4.04 and from 4 to 5, respectively, indicating that stakeholders tended to agree and strongly agree, respectively, with the proposed statements. This study assisted the prosthodontics department in creating a set of prevalidated questions with known difficulty and discrimination capacity.

Perception of the Contribution of Video Demonstrations in Dental Practical Training

Objectives: Information and communication technologies (ICT) have become integral part of our our students’ daily lives. Their use in practical teaching facilitates the learning process. With the occurrence of the COVID-19 pandemic, demonstration videos were integrated into the pre-clinical practical activities. This work aims to evaluate the students’ appreciation of the demonstration videos made for the pre-clinical practical activities (PPA) of the removable partial denture for the students of the 5th semester.Methods: The Removable Prosthodontics Department professors produced 10-minute didactic video recordings describing the themes of the pre-clinical practice activities. A descriptive cross-sectional study was conducted during the 2021–2022 academic year to assess students’ perceptions of the effectiveness and relevance of these videos. Data were collected using an anonymous questionnaire given to student volunteers at the end of the third year (June 2022).Results: The majority of students favorably appreciated the role of videos in saving time during the session, reducing stress, and better understanding of practical gestures, as well as the average length of videos, the quality of videos in terms of sound, magnification, and the usefulness of text annotations.Conclusion: Videos allow students to preview the practical gestures severaltimes before the PPA session to better see the demonstration with sufficient magnification and to reduce stress. Both techniques have proven to be effective, and their combination will bring better satisfaction to the students.

Identifying barriers and strategies for achieving competency in removable prosthodontics in undergraduate dental students: a mixed-method study

BackgroundDeveloping competency in removable prosthodontics (RP) is challenging for undergraduate dental students because it involves threshold concepts and tacit knowledge. Understanding this process can enhance learning and professional development in RP. The objective of this study was to identify the barriers hindering knowledge (threshold concept) and skill (tacit knowledge) development, and to propose strategies for achieving RP competency.MethodsAdopting critical theory, quantitative and qualitative approaches were implemented. The participants were third- to sixth-year dental students and recent dental school graduates. An online questionnaire was used to investigate the knowledge and skills required for achieving RP competency and barriers to RP competency development. Four focus groups were conducted to gather in-depth information. The data was analyzed using descriptive statistics and thematic analysis.ResultsA total of 322 respondents completed the questionnaire (67% response rate), and 26 of them participated in focus group interviews. The four threshold concepts to achieve RP competency were the basic principles of RP, removable partial denture design, occlusion, and dental materials. The two main tacit knowledges were impression making and material handling skills. The curriculum should integrate strategies to assist dental students in overcoming intrinsic barriers such as self-experience, revision, and spatial-temporal relationship, along with extrinsic factors such as clinical correlations of content, discussions, and immediate feedback.ConclusionsThreshold concepts and tacit knowledge in RP for undergraduate dental students have been proposed The strategies to overcome barriers comprise intrinsic and extrinsic factors that include the adoption of experiential learning. This study suggests effective teaching methods and learning strategies to maximize student learning and RP competency development when designing the undergraduate RP curriculum in dental education.

Virtual and Interprofessional Objective Structured Clinical Examination in Dentistry and Dental Technology: Development and User Evaluations.

Interprofessional education (IPE) facilitates interprofessional collaborative practice (IPCP) to encourage teamwork among dental care professionals and is increasingly becoming a part of training programs for dental and dental technology students. However, the focus of previous IPE and IPCP studies has largely been on subjective student and instructor perceptions without including objective assessments of collaborative practice as an outcome measure. The purposes of this study were to develop the framework for a novel virtual and interprofessional objective structured clinical examination (viOSCE) applicable to dental and dental technology students, to assess the effectiveness of the framework as a tool for measuring the outcomes of IPE, and to promote IPCP among dental and dental technology students. The framework of the proposed novel viOSCE was developed using the modified Delphi method and then piloted. The lead researcher and a group of experts determined the content and scoring system. Subjective data were collected using the Readiness for Interprofessional Learning Scale and a self-made scale, and objective data were collected using examiner ratings. Data were analyzed using nonparametric tests. We successfully developed a viOSCE framework applicable to dental and dental technology students. Of 50 students, 32 (64%) participated in the pilot study and completed the questionnaires. On the basis of the Readiness for Interprofessional Learning Scale, the subjective evaluation indicated that teamwork skills were improved, and the only statistically significant difference in participant motivation between the 2 professional groups was in the mutual evaluation scale (P=.004). For the viOSCE evaluation scale, the difference between the professional groups in removable prosthodontics was statistically significant, and a trend for negative correlation between subjective and objective scores was noted, but it was not statistically significant. The results confirm that viOSCE can be used as an objective evaluation tool to assess the outcomes of IPE and IPCP. This study also revealed an interesting relationship between mutual evaluation and IPCP results, further demonstrating that the IPE and IPCP results urgently need to be supplemented with objective evaluation tools. Therefore, the implementation of viOSCE as part of a large and more complete objective structured clinical examination to test the ability of students to meet undergraduate graduation requirements will be the focus of our future studies.

Evaluation of retentive force between stud and resilient telescopic crown attachment for implant-retained mandibular overdentures

Purpose This study aimed to evaluate the retentive force between stud and resilient telescopic crown attachments for implant-retained mandibular overdenture. Patients and methods A total of 20 male patients were selected from the Clinic of Removable Prosthodontics Department. Faculty of Dentistry, Sinai University (Kantara). Patients were divided into two equal groups. Group I (control group): patients were treated with two implants of 3.7 mm diameter and 13 mm length (in the canine regions), retaining mandibular overdentures with ball abutments, and by conventional maxillary complete dentures. Group II: patients were treated with two implants of 3.7 mm diameter and 13 mm length (in the canine regions), retaining mandibular overdentures with conical abutments with a 6° taper, and by conventional maxillary complete dentures. Retention force was recorded at the time of insertion (T0), 6 months (T6), and 12 months (T12) later. Results One-way anova revealed significant differences between the two groups in initial retention forces (T0). However, no significant difference was observed between the two groups at T6 and T12. Group II (telescopic attachment) was associated with significantly higher retention losses than Group I (ball attachment). In comparing the mean retention loss values for the two groups at different follow-up periods, significant differences were observed for both groups. Conclusion Within the limitations of this study, it can be concluded that: telescopic attachment with taper 6° can provide acceptable retention compared to ball and socket attachment during 12 months of overdenture use.

Epidemiological profile of patients attending the maxillofacial prosthodontics unit at Ibn Sina University Hospital in Rabat, Morocco: a cross-sectional study.

the present study aimed to establish an epidemiological profile of patients consulting the unit of maxillofacial prosthodontics in Rabat. Results deriving from this study will help enhance the quality of patient care in our center and can also serve as a comparison tool with other maxillofacial teams around the world. during 11 months all patients consulting the unit of maxillofacial prosthodontics in our center were included. We opted for a questionnaire with 3 variables: socio-demographics, clinical examination data, and the type of prosthetic treatment adopted. The study was conducted in the Department of Removable Prosthodontics in the Center of Consultation and Dental Treatment of Rabat Morocco (CCDTR) from September 2020 to July 2021. the study population consisted of 91 patients, with a majority of male patients at 53% (n=48). During our study period, the proportion of patients under one-year-old was predominant, accounting for 38.4% (n=35) of the total sample. Among the patients in the sample, 72.5% (n=66) had no profession, while 66% (n=60) had a low income. Regarding medical insurance, the majority of our patients, 85.5% (n=78), were covered by Public Health Insurance for the Low-income Population (PHILP). Among the total sample, 57.1% (n=52) consulted for a combination of pain function and aesthetics. Additionally, 61.5% (n=56) were referred by teaching hospitals. For the type of oro-facial defect, 52.7% (n=48) of the sample consisted of newborns with congenital facial cleft. Out of the 91 patients, 36 had maxillofacial tumors, with 47.6% (n=17) of them presenting squamous cell carcinoma. Furthermore, 63.7% (n=58) of the prosthetic treatments adopted involved presurgical orthopedic treatments for newborns with facial cleft. the study on the epidemiological profile of patients attending the maxillofacial prosthodontics unit at Ibn Sina University Hospital in Rabat, Morocco provides important insights. The findings highlight the predominance of male patients and the prevalence of oro-facial defects in newborns. Socioeconomic factors, such as low income and lack of profession, are significant considerations. The majority of patients are covered by the PHILP, indicating the importance of medical insurance. These findings contribute to improving healthcare planning and specialized care for this patient population.

Clinical use of digital applications for diagnostic and treatment planning in prosthodontics: A scoping review.

This scoping review aimed to compile and evaluate clinical trials investigating digital applications in prosthetic diagnostics and treatment planning by assessing their clinical relevance and future potential. Following the PCC-framework for scoping reviews and combining the source of analysis (Population/P: "prosthodontics"), the technique of interest (Concept/C: "digital application") and the field of interest (Context/C: "diagnostics"), a three-pronged search strategy was applied in the database PubMed and Web of Science. Clinical trials (≥10 study participants, English/German) were considered until 2023-03-09. Reporting adhered to the PRISMA-ScR statement. The search identified 520 titles, of which 18 full-texts met the inclusion criteria for data extraction. The trials involved a total of 14,457 study participants and were mapped for prosthetic subdisciplines: fixed (n = 9; 50%) and removable (n = 4; 22%) prosthodontics, reconstructive dentistry in general (n = 3; 17%), and temporo-mandibular joint disorders (n = 2; 11%). Data merging of medical format files, as DICOM+STL, was the dominant digital application (n = 7; 39%); and virtual treatment simulation using digital smile design or digital wax-up represented the most frequent prosthetic diagnostics (n = 6; 33%). This scoping review identified a relatively low number of clinical trials. The future potential of digital diagnostics appears to be mostly related to the subdiscipline of fixed prosthodontics, especially regarding virtual treatment simulation for communication with the patient and among dental professionals. Artificial intelligence emerged as a key technology in many of the identified studies. Further research in this area is needed to explore the capabilities of digital technologies in prosthetic diagnostics and treatment planning.

A Cross-sectional Study of Self-confidence Differences in Removable Prosthodontic Treatment among Undergraduate Students of a Saudi Dental School

Background: Removable denture treatments remain an option for the edentulous population in terms of oral rehabilitation. In dentistry schools, improving students' self-confidence in performing prosthodontic procedures should be paramount. Objectives: The aim of this study was to examine students' self-confidence perceptions in performing removable partial dentures (RPDs) and complete dentures (CDs) treatments and to draw attention to the steps in which they felt most and least prepared to do so without close supervision. Methods: This cross-sectional study was conducted at one dental school in Saudi Arabia at the end of the 2022-2023 academic year. A total of (n=96) undergraduate students in their clinical years, 5th and 6th cohorts, were included in this study. These students were requested to participate in a closed questionnaire consisting of 38 items that focused on self-reported confidence and the perceived quality of their education. A non-parametric test, the Mann-Whitney U-test, was used to compare between groups. The data were analyzed using IBM SPSS Statistics (V.28.0). Results: A response rate of 95.8% was achieved. Over the course of their studies, students' sense of confidence grew. Also, males were more confident than females in performing all clinical procedures. Overall, students were satisfied with their prosthodontic education, except for pre-clinical sessions and learning materials. Increasing their clinical experience would be most advantageous for boosting their confidence levels. Conclusion: The study revealed where students were most and least confident in carrying out removable prosthodontics. Students require supervision during their internship year because they reported average confidence in removable prosthodontic procedures. The results also point to the need for more research into the confidence gaps between males and females. The pre-clinical curriculum necessitates updating and more didactic teaching.

A survey on utilization and barriers of digital removable prostheses in the US dental education.

Gaining knowledge on the extent of digital technology implementation in dental education and the barriers to it will help inform future directions to promote the use of such technology and will enhance dental education. This study aimed to investigate the utilization of digitally fabricated removable prostheses and the potential obstacles to implementing such technology in US dental schools. A survey was developed and distributed to the restorative dentistry department chairs and postdoctoral prosthodontic program directors. The survey delivery protocol included follow-up emails 1 week, 3 weeks, and 4 weeks after the initial email. The collected data were analyzed descriptively. The response rate was 85% and 45% for predoctoral and postdoctoral prosthodontic programs, respectively. The results showed that 88.06% of the predoctoral programs and 95.65% of the postdoctoral prosthodontic programs implement digital complete dentures in the curriculum; however, the digital removable partial dentures implementation rate was recorded at 70.77% in predoctoral programs and 61.9% in postdoctoral prosthodontic programs. Dental schools are challenged by cost, design software limitations, IT and laboratory support, and faculty training. Multifaceted support is instrumental in further implementing digital removable prosthodontics into dental education.

Articulators in Prosthodontics and Dentofacial Orthopedics

The advanced dental technology has enabled prosthodontists and general dental practitioners to provide accurate prosthodontic treatments to patients. The dental articulator is an indispensable tool to enhance the quality of delivered work and increase patient satisfaction (1). The aim of this review paper is to provide an overview of articulators in dentistry, particularly in fixed and removable prosthodontics, their different types or classifications, indications, advantages, and limitations

Using Peek as a Framework Material for Maxillofacial Silicone Prosthesis: An In Vitro Study.

There are often bonding problems between acrylic resins and silicone. PEEK (polyetheretherketone), which is a high-performance polymer, has great potential for the implant, and fixed or removable prosthodontics. The aim of this study was to evaluate the effect of different surface treatments on PEEK to be bonded to maxillofacial silicone elastomers. A total of 48 specimens were fabricated from either PEEK or PMMA (Polymethylmethacrylate) (n = 8). PMMA specimens acted as a positive control group. PEEK specimens were divided into five study groups as surface treatments as control PEEK, silica-coating, plasma etching, grinding, or nano-second fiber laser. Surface topographies were evaluated by scanning electron microscopy (SEM). A platinum-primer was used on top of all specimens including control groups prior to silicone polymerization. The peel bond strength of the specimens to a platinum-type silicone elastomer was tested at a cross-head speed of 5 mm/min. The data were statistically analyzed (α = 0.05). The control PEEK group showed the highest bond strength (p < 0.05) among the groups. No statistical difference was found between control PEEK, grinding, or plasma etching groups (p > 0.05). The lowest bond strength was seen in the laser group, which was not statistically different from silica-coating (p > 0.05), and statistically different from control PEEK, grinding, or plasma groups (p < 0.05). Positive control PMMA specimens had statistically lower bond strength than either control PEEK or plasma etching groups (p < 0.05). All specimens exhibited adhesive failure after a peel test. The study results indicate that PEEK could serve as a potential alternative substructure for implant-retained silicone prostheses.

Self-assessment skills of undergraduate dental students in the preclinical course of complete removable prosthodontics at Tehran University of Medical Sciences.

This study evaluated the self-assessment skills of third-year dental students regarding their performance in complete removable prosthodontics (CRP) preclinical course. This cross-sectional study was conducted on all third-year dental students attending the International Dental College of Tehran University of Medical Sciences. The students were requested to self-assess their performance in primary impression making, custom tray fabrication, border moulding, final impression making, master cast fabrication, record-base fabrication and tooth arrangement in CRP preclinical course. The performance of dental students in each step was scored by themselves and their mentors. Data were analysed by the Mann-Whitney U, Pearson's correlation and t-tests (α = 0.05). Totally 25 male (55.6%) and 20 female (44.4%) dental students were evaluated. Significant differences were noted between male and female dental students in self-assessment scores regarding adequate extension of the custom tray (p = .027), the correct position of tray handle (p = .020), visibility of vestibular width and depth on the cast (p = .011), the coincidence of upper and lower midlines (p = .005) and correct orientation of maxillary and mandibular planes in the articulator (p = .036). The mean self-assessment score of female students was significantly higher than that of male students (p = .01). The scores given by the mentors were not significantly different for male and female students (p = .975). The difference between the self-assessment score of students and the mentor score was not significant (p = .067) either in males or in females (p > .05). Undergraduate dental students favourably self-assessed their performance in all steps of the preclinical course of CRP, comparable with their mentor assessment.

Application of Robotic Technology in Prosthodontics

There is a huge technical leap in dentistry from the traditional manual methods toward digital technology. The invention of robots has minimized manual efforts in hazardous working environments thus leading to better accuracy and precision of the work. Robotic application in prosthetic dentistry is utilized for removable prosthodontics and implant surgeries. The time required to complete each procedure is expected to be considerably reduced with the use of robots.

Evaluation of the Application of Undergraduate Pre-Clinical Removable Prosthodontic Laboratory Teaching in General Dental Practice

Background: Pre-clinical removable prosthodontic training is an integral part of undergraduate curriculum. The objectives of the study were to evaluate the application of pre-clinical removable prosthodontic laboratory training in general dental practice and relevance of its teaching in undergraduate curriculum. Methods: A descriptive questionnaire was developed to assess the extent of practice of pre-clinical removable prosthodontic lab skills in their dental practice. The responses were evaluated and statistically analyzed with a significance value of p&amp;lt;0.05. Three hundred-fifty-seven general dental practitioners participated in the study. Results: 91% with 20 years of dental practice responded positively on the application of prosthodontic training in their practice. 55.7% with two years of training agreed to dedicate more time to clinical prosthodontics training. Conclusions: 52.9% of the respondents agreed that it would be better to dedicate more time on clinical prosthodontics training rather than pre-clinical removable prosthodontics lab training as a part of the undergraduate prosthodontic curriculum, among which more than 60% of the study participants had two or more years of removable prosthodontics pre-clinical training during dental school. Practical implications: Clinical expertise of dental graduate is an essential component in the general dental practice. Hence, there is a need to revisit removable prosthodontic curriculum content and time distribution in undergraduate dental program.
