Implant-Supported Vertical Soft Tissue Augmentation for Severe Hard and Soft Tissue Deficiencies at Malpositioned Implants: A Case Report of a Mucogingival and Restorative Approach.

The management of severe mucogingival deformities surrounding malpositioned implants represents a complex issue with a high risk of aesthetic failure. The present case report describes a mucogingival and restorative approach for the treatment of severe localized peri-implant tissue deficiencies with interproximal bone loss combined with an interproximal gingival recession on the adjacent natural tooth. This consists of maintaining a non-restorable malpositioned implant, submerging it through one or multiple vertical soft tissue augmentations, according to the defect severity, and delivering a tooth supported bridge involving the adjacent natural teeth. The step-by-step surgical technique adopted for implant submergence and vertical soft tissue grafting, as well as the subsequent surgical and prosthetic interventions, are described, presenting results at 5 years from implant submergence and 3 years from prosthetic finalization.

Impact of AI-Oriented Live-Streaming E-Commerce Service Failures on Consumer Disengagement—Empirical Evidence from China

Despite the popularity of AI-oriented e-commerce live-streaming, the service failures that can result from real-time interaction and instant transactions have not been taken seriously. This study aims to assess the failure of AI-oriented live-streaming e-commerce services and help retailers identify various risks. Based on expectancy disconfirmation theory and a stressor–strain–outcome framework, this study identified a comprehensive framework including information, functional, system, interaction, and aesthetic failures. The structural equation modeling (SEM) method is used to further examine its effect on consumers’ discontinuance behavior. Further research reveals the mediating role of consumer disappointment and emotional exhaustion, as well as the moderating role of the live-streaming platform type. These results shed light on the negative influence of AI-oriented live-streaming e-commerce service failures and contribute to the literature on live-streaming commerce, service failure, and virtual streamers.

IMMEDIATE RESTORATION CUSTOM-MADE BY ADDITIVE MANUFACTURING ABOUT DENTAL IMPLANTS: PREDICTABLE RESULTS FOR PINK AND WHITE ESTHETICS

The definition of dental implant failure has evolved from focusing solely on lack of osseointegration to encompass broader concerns such as aesthetics. However, the criteria for aesthetic failure in implant dentistry are not well defined. Although several aesthetic indices have been validated to objectively evaluate clinical outcomes, including failure of an implant-supported crown. In this sense, aesthetic flaws in implant dentistry can be categorized into pink and white tissue flaws. This study aims to describe an extensive rehabilitation protocol where implants were placed using printed surgical guides and adaptations for bone and tissue grafts, facilitating restoration in the aesthetic zone. Key clinical stages and aspects are illustrated through the case of a fractured upper left central incisor, where an implant system was used for immediate patient rehabilitation. By highlighting these crucial steps and considerations, this study underscores the effectiveness of immediate implantation and restoration techniques in achieving optimal aesthetic and functional outcomes in dental rehabilitation

Dental bicortical basal implant in anterior maxillary region with immediate loading in a patient of diabetic profile – A case study

Anterior maxilla continues to present with height risk for aesthetic failure, and as a result their is a clear need modifications that would allow for natural looking restorations that are harmonious with the rest of the mouth.To aim of this study was to evaluate the results of single tooth implant treatment in diabetic patient where the teeth have been lost as a result of trauma. Bicortical basal implant for rehabilitation of mouth is gaining popularity and emerging as a gold stranded technique in recent times. This approach help in improvising the patient aesthetic for a longer duration and provide a permanent solution. Bicortical screw are implanted in heavily corticated bone (basal bone) and is less vulnerable to infection and failure. In patients with diabetic history convention dental implants is generally contraindicated and has high failure rate. To overcome this and provide a better solution need of alternative treatments has arisen. In our study of a case report, we used bicortical dental implant for replacing the missing maxillary anterior tooth with fixed prosthetic. Interesting, though, the patients had diabetes. We found positive out come with favourable prognosis. No any significant complications were noticed and implant was successful. A Retrospective studies of various published literature and observation of our patient for a period of 12 month. We conclude that bicortical dental implants with immediate loading may be used for rehabilitating mouth in diabetes patient after evaluation of various factors such as, blood sugar levels, Cost, time and preference of patient.

Color stability of two different resin matrix ceramics: randomized clinical trial

BackgroundOne of the most common causes of aesthetic failure and restoration replacement is the tooth restorations color mismatch specifically after aging.MethodsOne hundred and two participants with endodontically treated first molar were selected clinically. The patients were randomly splited into two groups and restored either with Cerasmart hybrid ceramic or Vita Enamic polymer infiltrated ceramic network (PICN) crowns and cemented using dual cure adhesive cement. The color difference (ΔE) values after cementation at 0 (Baseline), 6, and 12 months of use were obtained by quantification of L*, a*, and b* values with a digital spectrophotometer. Mann–Whitney test used to compare between tested groups at each time point and between (α = 0.05).ResultsAt 6 months follow-up intervals, Vita Enamic group showed the highest significant ∆L* (p = 0.035) and ∆a* (p < 0.001) compared to Cerasmart group. ∆b* and ∆E showed no significant difference between both groups (p > 0.05). Furthermore, all color parameters of both groups showed statistically significant difference at 12 months follow-up intervals. After 12 months, Vita Enamic restorations presented higher color change compared to Cerasmart restorations with a (p-value of 0.0120). When comparing the total color difference ∆Et through-out the follow-up intervals of Vita Enamic & Cerasmart groups, there were insignificant difference (p = 0.263).ConclusionBoth hybrid materials demonstrated comparable color stability after 1 year of clinical service within clinical acceptance range. However, Cerasmart demonstrated a better colour stability after 1 year.Trial registrationClinicalTrials.gov (ID: NCT05501808) 15/8/ 2022- ‘retrospectively registered’.

Staining ability of herbal tea preparations on a nano-filled composite restorative material - an in-vitro study.

Background: Discoloration of tooth-colored restorations due to various factors is one of the principal causes behind the failure of aesthetics. There has been an surge in the consumption of herbal beverages in recent times and the dietary factors play a potential role in the discoloration tooth-coloured restorations. This study was done to juxtapose the staining ability of green tea (GT), moringa tea (MT), and hibiscus tea (HT) on a nano-filled composite restorative material. Methods: The study was conducted in-vitro on composite samples prepared using moulds. 112 discs were prepared from Filtek TM Z350XT composite using a brass mould lined with mylar strips. Samples were divided into GT, MT, HT, and artificial saliva (AS) groups and immersed in freshly prepared beverages for 15 minutes each day for 45 days. Digital reflectance spectrophotometer was utilized to record color at baseline, 30, and 45 days. Repeated-measures ANOVA with a post-hoc Bonferroni test was used to compare groups within each group. ANOVA with a post-hoc Games Howell test was used to compare mean differences in ΔE among the groups. Results: Maximum discoloration was observed in the GT, followed by HT and MT, with the least being in the AS group at the end of 30 and 45 days (P<0.001 and P<0.001) respectively. Conclusions: The universal nano-filled composite material showed clinically detectable discoloration when exposed to Green Tea, Hibiscus Tea, and Moringa Tea which increased with time. Herbal beverages have the potential to cause discoloration of the composite resin which is often the choice of material for anterior aesthetic restorations.

The art of failure in Jean Rhys's Voyage in the Dark and Una Marson's The Moth and the Star

ABSTRACT Though both writers migrated from the Caribbean and lived at the same time in England in the 1930s, Jean Rhys (1890–1979) and Una Marson (1905–1965) did not run in the same circles – or know of each other. Marson's poetry and plays emerge from her anticolonial, feminist political commitments while Rhys has often been read as an isolated figure in modernist and Caribbean literary histories. They each had a complicated relationship to both European modernism and to mid-twentieth-century Anglophone Caribbean literature. Rhys and Marson have been put in implicit conversation in the wake of the new modernist studies because they are uneasily positioned within familiar canons of twentieth-century literature. Importantly, as this article argues, both writers also focus on failure – personal, aesthetic, and political – in their key works exploring migration in the 1930s – Rhys's novel Voyage in the Dark (1934) and Marson's poetry collection The Moth and the Star (1937). Failure in these texts is double sided, recasting personal and aesthetic failure as the failure of dominant narratives to recognize their characters. Reading these texts together, this article argues that late colonial women writers at once registered and challenged dominant conceptions of failure in their reconstruction of inherited forms.

Mechanical failures of dental implants and supported prostheses: A systematic review.

Though, mechanical dental implant and supported prosthesis failures are considered significant, a comprehensive evaluation is lacking. A systematic review analyzing different aspects related to such failures was therefore done. - Electronic search was carried out in PubMed/MEDLINE and Cochrane Library for articles published between 1981 and 2021. Articles were selected using predefined criteria. Data extraction was based on mechanical complications associated with dental implants, prosthetic implant failures, survival rate of implants, mechanical failure of implants placed in the maxilla and mandible, and mechanical complications associated with implant supported over dentures. Quality of included studies was assessed. Meta-analysis for heterogenicity testing, publication bias and implant failure assessment was conducted using MedCalc® Statistical Software version 19.7. - Eighteen retrospective and prospective studies were included following PRISMA guidelines. Mechanical complications were more in the initial 9 years but reduced later. Abutment screw loosening was one of the more common mechanical complications (16.21%). Maxillary implant failure was greater compared to mandibular implant failure with an odds ratio of 4.66 (95% CI -3.21- 6.75). Failure of implant supported overdentures due to mechanical complications were 3% in the fixed effect, and 2.9% in the random effect model (P<0.05). The overall prevalence of mechanical failure was between 5.6% and 7.7% (P<0.05). Mechanical failures of implant and supported prosthesis have similar prevalence to biological and esthetic failures, and therefore need to be given due credence. Identifying specific factors contributing to such failures can help reduce incidence.

Implant–Prosthetic Rehabilitation of Maxillary Lateral Incisor Agenesis with Narrow Diameter Implants and Metal–Ceramic vs. All-Ceramic Single Crowns: A 16-Year Prospective Clinical Study

The main objectives of the present prospective clinical study were to evaluate the marginal bone resorption and the peri-implant soft tissue conditions around narrow diameter implants, as well as the clinical performances of metal–ceramic and all-ceramic single crowns in the implant–prosthetic treatment of maxillary lateral incisors agenesis. Seventy-two patients affected by monolateral or bilateral agenesis of the maxillary lateral incisors were included in the study, and a total of 105 narrow diameter implants were inserted. The final single crowns were fabricated 4 months after the surgical procedures by means of either titanium abutments with Auro-Galvan Crowns (AGC) veneered with feldspathic ceramics or zirconia abutments with all-ceramic (alumina or zirconia) crowns layered with dedicated veneering ceramics. Both marginal bone resorption and soft tissue quality were evaluated after a maximum period of 16 years. Two independent survival curves for patients wearing AGC or all-ceramic crowns were calculated by means of Kaplan–Meier analysis, and a log-rank test was performed in order to compare these curves (p &lt; 0.05). After 16 years of clinical function, a mean marginal bone resorption of 1.2 ± 0.61 mm and good response of peri-implant soft tissues were observed. Descriptive statistics resulted in 80% and 87.1% cumulative success rates for patients provided with AGC prostheses onto titanium abutments and all-ceramic crowns on-to zirconia abutments, respectively. The cumulative survival rate calculated for AGC group was 93.3%, whereas all-ceramic group showed a cumulative survival rate of 95.7%. No statistically significant differences were found with the log-rank tests. The overall success and survival rates calculated were 85% and 95% for all the restorations, respectively. Mucositis, abutment unscrewing, loss of retention, chipping, core fracture, and esthetic failure were the major complications reported. The implant–prosthetic approach can be considered an effective and viable solution to treat cases of maxillary lateral incisor agenesis in the long term.

Fixed Prosthesis Failures: Survey among Moroccan Dentists

Introduction: The fixed prosthesis reveals many prosthetic complications, which occur most often by not respecting the appropriate means of approach. This error concerns both the clinic and the laboratory additionally it may be due to simply not knowing the right criteria of the different prosthetic conceptions. The main objective of this study, through a survey conducted among dentists practicing in different Moroccan cities, was to have a global overview of the incidence and prevalence of the different types of failures encountered in fixed prostheses and their different manifestations. Material and Method: This is a national descriptive survey that was conducted among 100 dentists practicing in the private and public sectors. Results: 63% of the dentists surveyed reported that pain was the most frequently encountered reason for consultations. The failure rate with ceramic crowns was 16% according to the dentists surveyed. Endodontic failures were the most frequent problem encountered by dentists with a rate of 66%. Periodontal failures were second with a percentage of 54% aesthetic failures were 36%. Conclusion: Fixed prosthesis is certainly one of the fields of dentistry in which the clinical and laboratory development is the most delicate. The approach must be global, to meet the biological, functional, aesthetic and comfort requirements of the patient.

Socket Shield Technique for Immediate Implant Placement in the Esthetic Zone: A Case Report

The placement of implant following removal of compromised tooth is a common practice. Hard and soft tissue changes following tooth extraction, particularly on the labial aspect are known to occur. These changes compromise aesthetics, particularly in anterior maxilla leading to esthetic failure. Socket shield technique is known to prevent resorption of buccal bone, maintaining contour of buccal mucosa and achieving better result aesthetically. The purpose of this case report is to demonstrate the socket shield technique for immediate implant placement in anterior maxilla and restoration with cement retained prosthesis.

Bucco-palatal implant position and its impact on soft tissue level in the maxillary esthetic zone.

The term "buccal implant position" is commonly used but lacks a precise definition and missing a reference point. Considering its major impact on peri-implantitis and esthetic failures the purpose of this study was to find a correlation between bucco-palatal implant positioning and the midfacial soft tissue level of implant crowns using newly defined Emergence-points. Patients with unilateral single-tooth implant crowns in the region of the central or lateral maxillary incisor were included in this study. Digital intraoral scans were superimposed over a scan of the master cast or the original digital data set and analyzed in a computer planning program. In relation to the corresponding natural tooth, an ideal Emergence-point (EIDEAL -point) was defined from a frontal view. The distance to the real Emergence-point (EREAL -point) of the implant crown was correlated to apical displacement (AD) of peri-implant soft tissue. The distance of the implant shoulder (I-point) to the real Emergence-point (EREAL -point) of the implant crown was also correlated to the AD of peri-implant soft tissue. In cross sections, the horizontal distance between EREAL - and I-point represents the sagittal implant position (SIP), and the vertical distance represents the vertical implant position (VIP). Seventy-three patients met the inclusion criteria. AD ranged from 0 to 3.5 mm (AD=0.87 ± 1.01), SIP from 0.2 to 5.1 mm (AD=2.66 ± 1.64). Statistical analysis showed a significant inverse correlation between AD and SIP (ρ= -.55, p <.001). VIP, the implant inclination, time span since implant insertion, and phenotype revealed no significant correlation to AD. The more palatal the implant was positioned, the less AD was observed. The position of the implant shoulder should preferably be planned more than 2 mm behind the ideal E-point. This E-point can be used for implant planning as it defines the ideal crown length for prospective planning.

Influence of Different Illuminants on Spectrophotometric Tooth Color Determination

Statement of problem: The vast majority of studies address the comparison of visual and instrumental tooth color determination. Although, the lighting conditions of the environment may affect the clinical shade matching performance. This study evaluated if and how different light sources can influence the spectrophotometric determination of natural tooth color. Purpose: The purpose of this study was to evaluate the precision of the spectrophotometer in tooth shade determination under the influence of different illuminants. Material and method: Three examiners, determined the shade of an upper central incisor with Vitapan 3D-Master (VITA Zahnfabrik, Bad Säckingen, Germany) and with the spectrophotometer (Vita Easyshade V, Vita Zahnfabrik, Bad Säckingen, Germany). A special fabricated device with eight light sources, designed to offer reproductible lighting conditions, was used to determine the efficiency of instrumental color determination under different illuminants. Results: Natural light (300 lux) and dental unit light at full intensity (32500 lux) produced the less ∆Eab modification. Color coordinates determined in the presence of halogen light (1800 lux), neon ambient light (3000 lux), LED with cold light (21200 lux), halogen light with neon ambient light (23400 lux), both warm and cold LED simultaneously (36000 lux) and all eight light sources of the device (44000 lux), suffered a slight modification of ∆E ab, which does not exceed the acceptability and the perceptibility threshold. The illuminant that caused the biggest modifications in color coordinates was LED warm light (1940 lux) with a ∆Eab 5.804 ± 0.271, that exceeds the acceptability and perceptability threshold. Conclusions: LED warm light influences the instrumental tooth color determination and when used, can lead to errors in communication of the color to the dental laboratory, which can cause esthetic failure of a prosthetic restoration. The best illuminant for color determination is natural light, or illuminants that simulate lighting in daily living conditions. Clinical implications: Based on the spectrophotometric readings, it was demonstrated that tooth color shifts with the change in ambient lighting conditions. Therefore, color determination should be performed with natural daylight illumination.

FAILURES IN FPD ? A CLINICAL SURVEY

The failures in xed partial denture are conditions that occur during or after appropriately performed xed prosthodontics treatment procedures. failures in xed prostho-dontics can be divided into biological, mechanical and esthetic factors of varied age group. The present study was conducted to assess biological, mechanical, and esthetic failure factors among xed partial dentures (FPDs).

The most frequent reason for failure was mechanical factors followed by biological,esthetic failure and biologic failure.The occlusal problem was the most common biological failure factor, the loss of retention was the most common cause of mechanical failure factor and the over contoured was accounted more when compared to other esthetic failure factors. By knowing the type of failures, we can plan a proper treatment plan so that the abutment will have a longClinical significance: time prognosis.

Assessing the gingival biotypes for better planning of esthetics in Indian population

Background: Anterior fixed prosthesis fabrication is a challenging one which involves many aspects and one among them which dictates the most is the gingiva. Any recession causes exposure of the tooth and prosthetic junction leading to esthetic failure. Hence it is important to know the biotypes before planning the restoration. Aim: To evaluate the prevalence of different gingival biotypes in individuals with relation to age, gender, tooth size and papillary height with respect to maxillary central incisors. Methods &amp; Materials: A total of 200 subjects in the range of 18-50 years participated in the study. Three clinical parameters were recorded which included crown width &amp; crown length ratio, papillary height and gingival transparency of two maxillary central incisors. The measurements were tabulated and statistically analyzed. Data was statistically analyzed using SSPS software. Results: The relationship of biotypes with clinical parameters was assessed using t test and chi square test. Thicker gingival biotype was more prevalent in male population with short, wider form of teeth whereas in females’ thin gingival biotypes with long and narrow teeth forms were observed. Conclusion: Both the young and old age groups have the same prevalence of thick gingival biotype.

Color stability of resin-based composites: Staining procedures with liquids-A narrative review.

The objective of this study was to review the experimental staining procedures performed in in-vitro studies for evaluating color stability of resin-based composites used for direct restorations. A review was performed with the purpose to identify in vitro procedures carried out to establish staining and color stability of resin-based composites used for direct restorations. A literature search was performed on four online databases (PubMed, Scopus, Embase and Web of Science) for articles published from January 1st 2001 till March 20th 2021, using a combination of free words and Medical Subject Headings (MESH) terms: "Composite Resins" AND "Color Stability" OR "Staining." Two reviewers screened titles and/or abstracts of 1728 unique studies. In total, 208 studies were selected for full-text reading, from which 178 were included in the review. The assessed variables were specimen dimensions, shape, and surface finishing; time before immersion; staining media type, dwell time, temperature and renewal interval; type of composite; color and translucency assessment parameters and measuring system. One hundred and seventy-eight articles analyzed color stability with staining liquids. Coffee was the most used staining medium (n=102), followed by tea (n=61), and red wine (n=55). A disc-shaped specimen was used in most studies (n=170) with a 2 mm thickness (n=116). Spectrophotometers were the most used color assessment devices (n=154), followed by colorimeters (n=17). Color differences were quantified with ΔE (n=154), ΔE00 (n=23). Acceptability and or perceptibility thresholds were also taken into consideration (n=126). The large variety of staining procedure suggests the need for standardization. Aesthetic failure due to discoloration is a relevant clinical problem. Evaluating benefits and drawbacks of resin based composites artificial staining procedures will improve to predict materials clinical performances.

Masticatory reflex: manifestation features at mucositis and periimplantitis

Relevance. In the middle of the last century, based on clinical and physiological studies, the head of the Department of Prosthodontics of the First Leningrad Medical Institute named after Academician I.P. Pavlov, Professor I.S. Rubinov, prepared a scientific base and formulated the doctrine of functional links and reflexes of the masticatory apparatus. In subsequent years, other scientists and clinicians clarified the features of the masticatory apparatus reflex manifestations and functional characteristics of masticatory units in various oral diseases. New characteristics of reflex formation in various pathological conditions of the masticatory apparatus we re revealed.Materials and methods. The paper presents data from a clinical and physiological study of the masticatory apparatus in 221 people of different age groups with implant-supported prostheses (two-stage endosseous implants). We studied the occlusal force using a gnathodynamometer and measured the muscle tone parameters at rest and the masticatory muscle contraction using a myotonometer. The study describes the masticatory apparatus musculoskeletal physiological reflex features and the manifestation in patients during dental rehabilitation, which was complicated by the gum and/or bone inflammation around the implants (mucositis and peri-implantitis ).Results. The study found that the development of an inflammatory process in the area of the dental implant in the form of mucositis or peri-implantitis did not lead to a protective change in the kinematics of the lower jaw movement to reduce the load on the masticatory link with developing pathology in the area of peri-implant tissues. The paper shows the pathophysiological features of the manifestation of the masticatory apparatus reflexes when restoring the integrity of dentition using prostheses. It describes the mechanisms of forming a vicious pathogenesis cycle in inflammation development in the tissues adjacent to artificial support.Conclusion. The clinical and physiological study substantiates the importance of routine preventive examinations, including radiographic examination, for timely diagnosis and treatment of an asymptomatic inflammatory process around a dental implant and an implant-supported restoration to avoid their premature functional and aesthetic failure.

Ambivalence and moral dilemmas in women's lived experiences of obesity and pregnancy: Qualitative insights for maternal lifestyle interventions.

Maternal obesity is a global health concern that is associated with significant effects on both short- and long-term health of both mother and child. However, maternal lifestyle interventions tend to focus solely on diet and physical activity in ways that disembody and disengage the social context in which women live their lives. The aim of this study was to explore the lived experiences of maternal obesity and delve into how experiences of the body and motherhood affect women's motivation for participating in a postpartum lifestyle intervention. A qualitative study using in-depth semi-structured interviews based on participant-generated photographs was used to allow the women to openly express their lived experiences of maternal obesity. The study emanated from a gynaecological department of a major Danish hospital, and five pregnant or postpartum women living with obesity participated. Interviews were audio recorded, transcribed and analysed using an Interpretive Phenomenological Approach. The analysis identified an overall theme of ambivalence and four subthemes among the participating women. The themes reflected contrasting feelings where the obese body was simultaneously an arena for aesthetic failure, functional success and moral dilemmas. Experiences of weight stigma and moral accusations in healthcare settings further increased the women's sense of ambivalence and challenged their strong desire to lose weight. This study highlights an ambivalent and vulnerable situation of maternal obesity which makes moral sensitivity towards weight and body concerns crucial to consider in future maternal health interventions. Our data suggest that an emphasis on functionality and capability rather than aesthetics and measured ideals would be useful in providing care and support in postpartum lifestyle interventions for women living with obesity.
