Prevalence of denture induced oral mucosal lesions in removable denture wearers

Background: Dentures can cause pathological problems to the oral tissues known as denture-induced mucosal lesions; the most common type is denture stomatitis. Objective: To estimate the frequency of denture-induced mucosal lesions among denture wearer patients attending oral diagnosis clinic /Faculty of Dentistry in Tishk International University. Patients and Methods: A patient who uses either removable partial or complete dentures was included. The patient’s gender and age, denture-related data, and oral lesions induced by dentures were evaluated. The data were statistically analyzed using chi-square and multivariate logistic regression. Results: Oral lesions (23.5%) were more common in males; the lesions found include denture stomatitis, denture hyperplasia, traumatic ulcers, and angular cheilitis. Denture stomatitis was the most common type (7%). The correlation between vertical dimension state and oral lesions was very highly significant. Conclusion: The major cause of denture-induced mucosal lesions was a change in denture vertical dimension and mostly a reduction in vertical dimension.

Accuracy of Digital Impression Taking in Partial Dentures: an in Vitro Study on the Degree of Adaptation of Rests

AbstractThe objective of the study is to assess the precision of digital impressions in removable partial dentures through an in vitro study on the degree of abutment adaptation. A Kennedy Class III model with a prosthetic space between elements 43 and 47, featuring niches in the mesio-occlusal and cingulum regions, respectively. Conventional impressions were performed in subgroups CONC and CONM, while digital scanning was conducted in subgroups DIGC and DIGM. Simplified cobalt-chromium alloy frameworks were manufactured using the lost-wax technique on plaster and resin models. The degree of adaptation of the structures was evaluated by impressing the niches with condensation silicone, qualitatively assessing perforations, and quantitatively measuring the mold thickness under a stereomicroscope after cross-sectioning. Regular adaptation was more prevalent among the experimental groups. CONC showed a higher mean degree of abutment adaptation, while CONM had a lower mean. The study factors, impression technique, and type of abutment seat, were not statistically significant, with no interaction among the variables. Occlusal and cingulum abutment measurement points, in both impression techniques, showed no statistically significant difference. Digital scanning yielded better results in terms of abutment adaptation, with smaller average gaps between the abutment seat and the metal structure, making it clinically acceptable. The type of abutment seat and the impression technique did not have a statistically significant impact on abutment adaptation. The impression technique does not represent a factor influencing the adaptation of occlusal and cingulum abutments at different measurement points. Keywords: 3D Printing. Removable Partial Denture.

The Potential of Artificial Intelligence in Prosthodontics: A Comprehensive Review.

Prosthodontics is a dental subspecialty that includes the preparation of dental prosthetics for missing or damaged teeth. It increasingly uses computer-assisted technologies for planning and preparing dental prosthetics. This study aims to present the findings from a systematic review of publications on artificial intelligence (AI) in prosthodontics to identify current trends and future opportunities. The review question was "What are the applications of AI in prosthodontics and how good is their performance in prosthodontics?" Electronic searching in the Web of Science, ScienceDirect, PubMed, and Cochrane Library was conducted. The search was limited to full text from January 2012 to January 2024. Quadas-2 was used for assessing quality and potential risk of bias for the selected studies. A total of 1925 studies were identified in the initial search. After removing the duplicates and applying exclusion criteria, a total of 30 studies were selected for this review. Results of the Quadas-2 assessment of included studies found that a total of 18.3% of studies were identified as low risk of bias studies, whereas 52.6% and 28.9% of included studies were identified as studies with high and unclear risk of bias, respectively. Although they are still developing, AI models have already shown promise in the areas of dental charting, tooth shade selection, automated restoration design, mapping the preparation finishing line, manufacturing casting optimization, predicting facial changes in patients wearing removable prostheses, and designing removable partial dentures.

Suitability and Trueness of the Removable Partial Denture Framework Fabricating by Polyether Ether Ketone with CAD-CAM Technology.

The object of the study was to evaluate the suitability and trueness of the removable partial denture (RPD) framework fabricated by polyether ether ketone (PEEK) with the CAD-CAM technology in vitro. Four different types of dentition defects were selected. In each type, five PEEK RPD frameworks were fabricated by the CAD-CAM technology, while five Co-Cr RPD frameworks were made by traditional casting. The suitability of the framework was evaluated by silicone rubber film slice measurement and the three-dimensional image overlay method. The trueness of the PEEK framework was detected by the three-dimensional image overlay method. Data were statistically analyzed with the use of an independent samples t-test (α = 0.05). The suitability values by silicone rubber film slice measurement of the PEEK group were lower than those of the Co-Cr group in four types, with the differences indicating statistical significance (p < 0.05) in type one, type two, and type four. The suitability values using the three-dimensional image overlay method showed no statistical differences (p > 0.05) between the two groups in four types. The trueness values of the PEEK group were within the allowable range of clinical error. The suitability and trueness of the PEEK RPD framework fabricated by CAD-CAM technology met the requirements of the clinical prosthesis.

Full-mouth rehabilitation in a patient with multiple caries: A case report

Background: Full-mouth rehabilitation of multiple caries can improve the quality of life. The selection of appropriate restorations on caries and teeth that have undergone post-endodontic treatment is critical to treatment success and enhances the quality of life. Purpose: This case report presents a full-mouth rehabilitation of a patient with multiple caries. Case: A 30-year-old man complained of multiple caries and pain in the posterior mandibular tooth, especially when eating and drinking (cold and hot), which interfered with his activities. The clinical examination found caries in teeth 16, 22, 24, 25, 26, 27, 36, 37, and 38 and a retained root of tooth 46. The percussion and biting tests were negative, while the sensibility test was positive. Case Management: Severe caries found in tooth 37 was managed with endodontic treatment and an indirect onlay restoration with lithium disilicate-based material. The retained tooth of 46 was extracted and restored with a partial denture. The other teeth, 16, 22, 24, 25, 26, 27, 36, 37, and 38, were treated by direct composite restoration. Holistic treatment was performed on all the problem teeth to support oral hygiene and was followed by dental health education. Conclusion: Full-mouth rehabilitation is essential for oral hygiene and can improve the quality of life. Education on maintaining oral hygiene is a must for protecting oral health.

Marginal fit of 3-unit implant-supported fixed partial dentures: Influence of pattern fabrication method and repeated porcelain firings.

Marginal fit significantly impacts the long-term success of dental restorations. Different pattern fabrication methods, including hand-waxing, milling, or 3D printing, may affect restorations accuracy. The effect of porcelain firing cycles on the marginal fit of metal-ceramic restorations remains controversial, with conflicting findings across studies. The aim was to evaluate the potential effects of multiple porcelain firings (3, 5, 7 cycles) as well as pattern fabrication method (conventional hand-waxing, milling, and 3D printing) on the marginal adaptation of 3-unit implant-supported metal-ceramic fixed partial dentures. It was hypothesized that neither the wax pattern fabrication method nor repeated ceramic firings would significantly affect the marginal adaptation of metal-ceramic crowns. In this in-vitro study, 30 Cobalt-Chromium alloy frameworks were fabricated based on pattern made through three techniques: conventional hand-waxing, CAD-CAM milling, and CAD-CAM 3D printing (n = 10 per group). Sixteen locations were marked on each abutment to measure the vertical marginal gap at four stages: before porcelain veneering and after 3, 5, and 7 firing cycles. The vertical marginal gap was measured using direct microscopic technique at ×80 magnification. Mean vertical marginal gap values were calculated and two-way ANOVA and Tukey's post hoc tests were used for inter-group comparisons (α = 0.05). The 3D printing group showed significantly lower (P<0.001) mean vertical marginal gaps (60-76 μm) compared to the milling (77-115 μm) and conventional hand-waxing (102-110 μm) groups. The milling group exhibited a significant vertical gap increase after 3 firing cycles (P<0.001); while the conventional (P = 0.429) and 3D printing groups (P = 0.501) showed no significant changes after 7 firing cycles. Notably, the vertical marginal gap in all groups remained below the clinically acceptable threshold of 120 μm. CAD-CAM 3D printing provided superior marginal fit compared to CAD-CAM milling and conventional hand-wax pattern fabrication methods. The impact of porcelain firing on the mean marginal gap was significant only in the milling group. All three fabrication techniques yielded clinically acceptable vertical marginal adaptation after repeated firings. Additive manufacturing holds promise to produce precise implant-supported prostheses.

A simplified and evidence-informed approach to designing removable partial dentures. Part 5. Design examples for Kennedy classifications

For many decades the literature has regularly reported that there is a discrepancy between what is taught in dental school and what is practiced, especially in the field of removable partial dentures. Not only that, but for more than 60 years reports from around the world have shown that, usually, the majority of clinicians abdicate their responsibility to design a removable partial denture (RPD) and instead leave this to the dental technician, who has no knowledge of the clinical condition of the patient and works only from a cast. Most patients around the world who require RPDs to improve aesthetics and chewing can only afford a removable prosthesis simply because the majority are poor. But RPDs can improve these aspects and contribute to an improved quality of life.

Efficacy of a Virtual 3D Simulation-Based Digital Training Module for Building Dental Technology Students' Long-Term Competency in Removable Partial Denture Design: Prospective Cohort Study.

Removable partial denture (RPD) design is crucial to long-term success in dental treatment, but shortcomings in RPD design training and competency acquisition among dental students have persisted for decades. Digital production is increasing in prevalence in stomatology, and a digital RPD (D-RPD) module, under the framework of the certified Objective Manipulative Skill Examination of Dental Technicians (OMEDT) system reported in our previous work, may improve on existing RPD training models for students. We aimed to determine the efficacy of a virtual 3D simulation-based progressive digital training module for RPD design compared to traditional training. We developed a prospective cohort study including dental technology students at the Stomatology College of Chongqing Medical University. Cohort 1 received traditional RPD design training (7 wk). Cohort 2 received D-RPD module training based on text and 2D sketches (7 wk). Cohort 3 received D-RPD module pilot training based on text and 2D sketches (4 wk) and continued to receive training based on 3D virtual casts of real patients (3 wk). RPD design tests based on virtual casts were conducted at 1 month and 1 year after training. We collected RPD design scores and the time spent to perform each assessment. We collected the RPD design scores and the time spent to perform each assessment at 1 month and 1 year after training. The study recruited 109 students, including 58 (53.2%) female and 51 male (56.8%) students. Cohort 1 scored the lowest and cohort 3 scored the highest in both tests (cohorts 1-3 at 1 mo: mean score 65.8, SD 21.5; mean score 81.9, SD 6.88; and mean score 85.3, SD 8.55, respectively; P<.001; cohorts 1-3 at 1 y: mean score 60.3, SD 16.7; mean score 75.5, SD 3.90; and mean score 90.9, SD 4.3, respectively; P<.001). The difference between cohorts in the time spent was not statistically significant at 1 month (cohorts 1-3: mean 2407.8, SD 1370.3 s; mean 1835.0, SD 1329.2 s; and mean 1790.3, SD 1195.5 s, respectively; P=.06) but was statistically significant at 1 year (cohorts 1-3: mean 2049.16, SD 1099.0 s; mean 1857.33, SD 587.39 s; and mean 2524.3, SD 566.37 s, respectively; P<.001). Intracohort comparisons indicated that the differences in scores at 1 month and 1 year were not statistically significant for cohort 1 (95% CI -2.1 to 13.0; P=.16), while cohort 3 obtained significantly higher scores 1 year later (95% CI 2.5-8.7; P=.001), and cohort 2 obtained significantly lower scores 1 year later (95% CI -8.8 to -3.9; P<.001). Cohort 3 obtained the highest score at both time points with retention of competency at 1 year, indicating that progressive D-RPD training including virtual 3D simulation facilitated improved competency in RPD design. The adoption of D-RPD training may benefit learning outcomes.

A digital workflow for designing and manufacturing metal frameworks and removable partial dentures: A novel dental technique.

The purpose of this technical report is to demonstrate a fully digital workflow for designing and fabricating metal frameworks and removable partial dentures. After obtaining a digital cast of the dental arch with bilateral distal extension defect, computer-aided design software and 3D printing technology are used for the design and fabrication of the removable partial denture frameworks, denture teeth, and denture bases, instead of the traditional workflow. The assembly of the three components is facilitated through a meticulously structured framework. The technology, which prints metal frameworks, denture bases, and denture teeth through different processes with different materials, achieves full 3D printing technology for making removable partial dentures.

Utilizing Intraoral Scanning and Computer-Aided Design/Manufacturing for Creating a New Dental Crown to Match an Existing Removable Prosthesis: A Case Report

This clinical report demonstrates the successful dental crown treatment for a 39-year-old female patient with a fractured posterior lower right second molar wearing a removable partial prosthesis and refusing to make a new one. The patient&amp;apos;s preference for a new dental crown on her lower right second molar was respected, and an intraoral scanner (IOS) was employed to capture the fractured abutment&amp;apos;s anatomy, which also serves as part of her removable denture. Following abutment preparation, a second IOS scan recorded the modified abutment. A temporary crown of the abutment was fabricated and secured to protect the prepared abutment. Comprehensive data, including an intraoral scan with an existing removable denture file, an intraoral scan without a removable denture, an intraoral scan of an unprepared abutment file, an intraoral scan of prepared abutment, and a digital photo of shade selection were transmitted to the dental laboratory. Utilizing computer-aided design/computer-aided manufacturing technology, a new dental crown compatible with the existing removable prosthesis was created. After fitting the new crown, occlusion, aesthetics, function, and attachment assessments were conducted to ensure optimal results. Subsequent follow-ups confirmed the patient&amp;apos;s satisfaction with the functionality, aesthetics, and fit of her removable partial denture with the new dental crown.

Metal-Ceramic Resin-Bonded Fixed Partial Dentures After a Mean Observation Time of 7.5 Years.

To generate data on the long-term survival of metal-ceramic resin-bonded fixed partial dentures (RBFPDs). A total of 89 patients received 94 RBFPDs, 5 of whom (women n = 1; men n = 4) received 2 RBFPDs each. All RBFPDs were fabricated as two-retainer end-abutment metal-ceramic restorations. Clinical follow-ups were performed 6 months after cementation and then annually thereafter. The mean observation time was 7.5 years. Cox regression was performed to test the effects of the variables: gender, location, arch, design, use of rubber dam, and adhesive luting system. Survival and success were calculated using Kaplan-Meier curves. As a secondary objective, patient and dentist satisfaction with the esthetics and function of the RBFPDs was evaluated. The significance level was set at α = .05 for all calculations. Estimated Kaplan-Meier failure-free survival was 97.5% (standard error [SE] 1.7) after 5 years and 83.3% (SE 5.3) after 10 years. Calculated intervention-free survival (success) was 90.1% (SE 3.4) after 5 years and 65.5% (SE 6.7) after 10 years. Debonding-free survival was 92.6% (SE 2.9) after 5 years and 80.6% (SE 5.4) after 10 years. Cox regression revealed that none of the four tested variables had a significant effect on the incidence of complications in RBFPDs. Patient and dentist satisfaction with RBFPD esthetics and function was consistently high throughout the observation period. Within the limitations of an observational study, RBFPDs achieved clinically successful outcomes over a mean observational period of 7.5 years.

Evaluation of retention for two different designs of digitally fabricated extracoronal attachments after 1 year of simulated aging

Objective To assess changes in dislodging forces for the OT-Cap and OT-Cap Tecno attachment-retained partial dentures throughout 1 year of simulated aging. Patients and methods Fourteen three-dimensional-printed class II mandibular models with last premolars prepared to receive splinted crowns with computer-assisted designing/computer-assisted manufacturing extracoronal attachment were divided into two groups; group I: seven partials retained by OT-Cap attachment and group II: seven partials retained by OT-Cap Tecno attachment. Dislodging forces were measured at baseline (T0), then after; 60 000 cycles of chewing simulation plus 270 cyclic dislodgements (T1), 120 000 cycles of chewing simulation plus 540 cyclic dislodgements (T2), and 240 000 cycles of chewing simulation plus 1080 cyclic dislodgements (T3). Results The independent t test revealed a nonsignificant difference between the mean value of initial retention for each group and the manufacturer specifications. It also revealed that group II exhibited; significantly higher mean values of retention at T1, T2, and T3 with P values (P = 0.002, P &lt; 0.001, and P = 0.016), and lower mean values of retention loss at 0–3 and 0–6 intervals with P values (P &lt; 0.001 and P = 0.011), but, higher mean values of retention loss at the 6–12 interval (P &lt; 0.001). As revealed by repeated-measures analysis of variance; the time-dependent loss of retention was expressed as: 0–3 months more than 3–6 months more than 6–12 months for the OT-Cap group (difference was significant between T2 and T3; P &lt; 0.05), and as; 0–3months less than 3–6 months less than 6–12 months for Tecno group (P &lt; 0.05). Conclusion The precision Tecno attachment offered higher and more durable retention and more uniform retention behavior than its semiprecision counterpart.

A comparative in vitro analysis of various temporization materials with respect to pulp chamber temperature changes during polymerization.

(1) To compare the temperature rise in the pulp chamber with different resin materials used for making provisional fixed partial dentures in anterior and posterior region while using Polyvinylsiloxane impression materials as matrix. (2) To identify a superior provisionalization material based on the amount of heat dissipated suitable for anterior and posterior provisional fixed partial denture fabrication. Temporary crowns and bridges are integral to Fixed Prosthodontics. It has been observed that conventional fixed prosthesis temporisation materials release heat due to the exothermic polymerisation reaction. When such a provisional material is directly let to set on a vital tooth, the heat transfer causes irreversible changes in the pulp tissue depending of the degree of change. Hence, this study observes amount of heat generation in various materials during temporisation procedure, by simulating similar conditions. Two Models were fabricated, one simulating missing lateral incisor (Model A) and another simulating missing first molar (Model B). Intact maxillary central incisors and canine for Model A and intact mandibular Second Premolar and Second Molar were selected to act as abutments. These abutment teeth were fitted with the tip of a K-type Thermocouple inside their pulp chambers and these were connected to a digital thermometer. Five temporisation materials were chosen for fabrication of temporary crowns through Direct technique. (1) polymethy methacrylate (Self Cure acrylic), (2) bisacryl composite (Protemp 4), (3) visible light cure urethane dimethacrylate (Revotec LC), (4) barium glass and fumed silica infused methacrylate (Dentsply Integrity) and (5)nano-hybrid composite (VOCO Structur 3). Ten observations were made for each provisional material on each model. During each observation, temperature rise was recorded at 30s interval from the time of application, through the peak and till a decrease in temperature is observed. Polyvinyl siloxane was used as matrix for all except light cure resin, where polypropylene sheet was used. Anova test used for statistical. ANOVA test revealed that there was a significant difference in the temperature changes associated with the provisional restorative materials used. Among the five, polymethy methacrylate (self cure resin) showed the maximum rise in temperature, followed by bisacryl composite (Protemp 4), visible light cure urethane dimethacrylate (Revotec LC), barium glass and fumed silica infused methacrylate (Dentsply Integrity) and nano-hybrid composite (VOCO Structur 3). There was no comparable difference between Model A and B but an overall reduction of temperature rise was observed in model B. VOCO Structur 3 showed the least temperature rise in the pulp chamber, and overall temperature rise was less for model B which can be attributed to the residual dentin thickness.

Dentist Dilemmas on Replacing Single Missing Teeth; Implant versus Fixed Partial Denture – A Survey among Practicing Dentists

ABSTRACT Background: Dental implant and fixed bridges are the common and acceptable means of prosthetic restoration of missing tooth. Although each is a viable treatment option, the implant restoration has definite advantages. A major shortcoming of the fixed bridge is the significant tooth reduction of the abutments. This study aimed to know the reasons that make some dentists choose a dental bridge in the edentulous area with adjacent sound teeth over the implant in cases suitable for implant. Materials and Methods: An observational questionnaire study was conducted between January and May 2022. An online questionnaire was sent to qualified dentists practicing in different cities of Saudi Arabia. Absolute frequencies were used to describe the data. Results: A total of 602 dentists received the questionnaire, and 430 responded, resulting in a response rate of 71.7%. The majority of responders (98%) recommended implant as a first choice to replace missing tooth when both implant and fixed bridge can be used in case of sound abutments. However, they mentioned factors such as cost of treatment, patient wishes, and patient’s medical condition act as an obstacle or difficulty to support their use of the implant in some cases. Conclusions: More efforts should be done to encourage dentists to select appropriate treatment option of proven scientific basis without any bias. Patients should be given more information about the advantages of implant over fixed partial denture and should be motivated. Finally, more support from implant companies should be encouraged as well as more knowledge and skill about implant dentistry should be gives during undergraduate courses.

Features of Hygienic Care for Removable Prostheses Made of Thermoplasts

As a result of the study, 74 patients with a diagnosis of dentition defects were made partial removable lamellar dentures from various structural dental materials. To identify the awareness of patients about the peculiarities of hygienic care for the oral cavity when using removable dentures, a preliminary survey of all respondents was conducted. The results of this survey demonstrated a low level of patient awareness of the specifics of hygienic procedures for the care of dentures. More than half of the respondents (52.4 %) did not have sufficient information about the rules and features of hygienic oral care when using removable orthopedic structures. Only 31 % of respondents cleaned removable dentures twice a day, more than half, 60 % cleaned the denture once a day. According to the results of the survey, 76.5 % of respondents revealed violations of the rules of personal oral hygiene. Additional hygiene products for the care of removable dentures in the form of cleaning tablets are used by 5.6 % of patients, 83.1 % of patients did not use additional hygiene products.

Patients' Perceptions Regarding Acceptance of Dental Implants as an Option for the Replacement of Missing Teeth: An Observational Study.

Dental implants enhance the self-assurance and overall well-being of individuals by providing oral comfort during mastication and a notable degree of contentment. The objectives of the present study were to assess patients' perception of opting or non-opting for dental implants as a replacement for missing teeth and to determine the correlation between various factors and perceived demand for dental implant treatment. A cross-sectional observational study was conducted on 214 partially edentulous individuals aged between 21 and 50 years. These patients sought treatment to replace their missing teeth. The participants were provided with detailed information regarding various options for replacing their missing teeth, including removable prostheses, fixed partial dentures, and dental implants. The researchers recorded and evaluated the reasons behind the patients' decision to opt for or decline dental implant treatment using the chi-squared test. Categorical variables were summarized as percentages (n %). The association between variables and binary data was examined using point biserial correlation, whereas, for continuous data, the Pearson correlation coefficient was employed. About 65 (30.4%) patients opted for dental implant treatment and 149 (69.6%) patients did not opt for dental implant treatment. Missing teeth were found in 120 women (56.08%) and 94 men (43.92%). The main reason for seeking dental implant treatment was the need for improvement in functions such as chewing in 65 (100%) patients, followed by the need for improvement in oral health in 57 (88%), aesthetics in 54 (83%), need for bone and adjacent teeth preservation in 52 (80%), and durability of dental implants in 46 (71%) patients. The main reasons for not seeking dental implant treatment and opting for fixed prostheses other than dental implantsor removable prostheses cost 149 (100%), fear of surgery 132 (91%), underlying health issues 121 (81%), lack of knowledge about dental implants 120 (80.5%), and time management issues 92 (62%). Gender, age, and number of missing teeth showed a negative correlation, whereas level of education, social status, and oral health awareness showed a positive correlation with the perceived need for dental implant treatment. Dental implant treatment was preferred by 30.4% of patients, which was influenced by gender, sex, level of education, social status, awareness of oral health, and number of missing teeth. Cost, fear of surgery, underlying medical conditions, lack of knowledge, and time management are some reasons for not opting for dental implant treatment.
