Personality not only marks an impression on others but also increases self confidence. Various studies have been conducted worldwide and have concluded that perception of aesthetics is completely subjective and is influenced by an individual’s choice based on age, gender, caste, region, social culture, level of education, profession, etc. But the fact cannot be denied that a charming smile can open the doors to new opportunities, success and adds to the wellbeing of a person. Studies have been continuously evaluating different aspects of smile design. Still it seeks an extensive review and proper compilation of available data considering different factors which probes the raveled aspects and draws guidelines to conduct a research to further address unanswered questions. Summary: Literature was reviewed by electronic search of Pubmed and Google Scholar. The review aimed at (1) highlighting the difference of perception between layperson and professionals (2) To assess the factors such as colour gradation, tooth form, buccal corridor triangle, gingival placement etc. Numerous articles were retrieved using specific keywords amongst which selected articles were reviewed based on inclusion criterias. Conclusion: This review complies and concludes the gist of perception, satisfaction or the dissatisfaction according to patients’ psyche and aims to help clinician to plan treatment accordingly to match the blend of demands, aesthetics and functions in anterior dental aesthetic zone.

The effect of implant abutment connection to the success of implant therapy was very less understood. Summary: The original external hex system (Branemark system) was used for many years, however various complications like screw failure and abmormal crestal bone loss were observed .Even single piece implants which had no such connection, were not successful in all cases. With the advent of time , platform switch concept came into existence which revolutionised the implant abutment junction systems . Various internal hex systems were also introduced each having its own advantages and disadvantages. The stress load performance , mechanical strength , microgaps, effect on biological width and crestal bone loss was different for various systems . Web based searches were made in various search engines like Pub Med , Ebsco , Scopus about the available implant abutment connection systems .","PeriodicalId":22708,"journal":{"name":"The Journal of the Indian Prosthodontic Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84517040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to evaluate correlation between lip form (according to a new classification given by Kim et al in 2017) and incisal display with lips in repose in young Indian population. Also to find most common type of Lip form present in young adults. Methodology: A total of 200 young voluntary subjects between age group 18-30 years were chosen randomly for the study. Facial photographic records were taken with lips in repose. Incisal display was measured manually by using digital Vernier calliper. Then type of lip form was classified using Image J software and also incisal display was measured digitally by the same software. Result: Out of 200 samples, 44 were males and 156 were females. The most common type of lip form was straight followed by moderate and high lip forms. The average incisal display in mm was 3.545 in females and 2.473 in males. A statistically significant difference was found between incisal display and lip form in female candidates. Conclusion: Most common type of lip form reported in young Indian population is straight lip form. Lip form can be used to determine incisal display in anterior restorations/prostheses.

A harmonious occlusal relation allows the prosthesis to function harmoniously without disturbing the stomatognathic system resulting in less number of temporomandibular disorders, bruxism habit, trauma from occlusion and other associated diseases. Summary: Over the years various modalities have been used to evaluate occlusion such as waxes, articulating papers, foil/ film/silk strips and newer materials such as the T-Scan, dental prescale and virtual dental patient. The reliability, sensitivity, marking ability and method of use are different and based on their type and character. Factors like oral environment, plastic deformity and interpretation of clinician is also a contributing factor. Hence a thorough knowledge about the various available occlusal indicator methods/modalities, their method of usage, understanding of interpretation & limitation is essential prior to their usage. This review will give insight to various modalities commonly available discussing evidence and practicality of their application. The clinical challenge is to prevent the consequence of occlusal discrepancies by making appropriate, evidence-based minimum adjustments to deliver a realistic treatment with reliable outcome. Conclusion: this presentation will comprehensively discuss the transition of occlusal evaluation methods from waxes, occlusal films to the latest & most resent digital modalities.

Patro","doi":"10.4103/0972-4052.306428","DOIUrl":"https://doi.org/10.4103/0972-4052.306428","url":null,"abstract":"S42 The Journal of Indian Prosthodontic Society | Volume 20 | Supplement 1 | December 2020 Introduction: Orofacial cleft is a common congenital anomaly, accounting global prevalence of 0.79 to 1.3 cases in 1000 live births. Cleft can manifest alone or in combination of cleft lip or palate which can either be unilateral or bilateral. Alveolar cleft is a common finding with concomitant occurrence in 75percent of total cases, an incidence of 1.8 to 2.5 in 1000 live births. Alveolar cleft can either derange normal teeth eruption pattern or lead to tooth agenesis with maxillary lateral incisor being the most commonly affected tooth. Missing teeth in cleft region are either orthodontically camouflaged or prosthodontically rehabilitated which conventionally includes use of removable or fixed partial dentures. Both these rehabilitations can cause potential damage of adjacent structures with esthetic shortcomings. Summary: Use of dental implants in grafted cleft site is an encouraging modality helping in overcoming these obstacles. However, to undertake this treatment, it is important to know appropriate time after grafting when implant can be placed. This paper aims to determine an appropriate time gap between grafting and implant placement in alveolar cleft patients via a systematic review of literature published between January 2011 and February 2020 (Via electronic search). Conclusion: Tertiary bone grafting is frequently required despite a positive history of previous grafting procedure. Successful implant-based rehabilitation was reported irrespective of the followed method. More studies, preferably in form of control trials, with detailed descriptions in terms of data acquired and procedural difficulties are required to sensitize clinicians about probable timelines and treatment outcomes. This will help in developing a universally acceptable protocol, making future comparisons easier and comprehensive.

Dental College & Hospital, Cuttack Introduction: CP titanium has been evolved as gold standard implant material at the end of twentieth century. Different designs, surface treatments, and alloying elements are still in ongoing search to obtain protection against stress corrosion crack, tribo-corrosion, and prevention against biofilm adhesion and release of titanium ions into tissue. To facilitate earlier and dynamic osseointegration and intimate mucosal contact studies are going on. In all these activities corrosion study is unevetable. Summary: By using electrochemical corrosion studies various parameters of corrosion behavior is studied in standard and extreme environmental conditions of pH, temperature, stress, and chemicals.

Ramaiah Dental College,Karnataka Introduction: All-ceramics systems have gained remarkable interest, amongst the metal free ceramic systems, due to their superior mechanical properties. However, veneer fractures and chipping in bilayered ceramic restorations present a major limitation. Methodology: Shear bond strength of commercially available core ceramics to veneering ceramics along with an experimental zirconia mica glass ceramics was evaluated. In addition, the interfacial core-veneer stresses were estimated using finite element modelling and co-related the results of shear bond strength with acoustic emission analysis. Three dimensional finite element models of ceramic core-veneer were modelled to simulate the experimental shear bond strength tests. Shear bond strength between core-veneer specimens were tested with a universal testing machine at a cross-head speed of 1mm/ min with acoustic emission (AE) sensors to investigate the material response such as fracture initiation and propagation. Result: High shear bond strength were observed in IPS e.max Press-IPS e.max Ceram with cohesive core fractures followed by Zirconia-IPS e.max Ceram with mixed mode fractures. Conclusion: Interfacial reactive bonding between glass ceramics of IPS e.max Press and IPS e.max Ceram direct the promotion of fusion glass-ceramic in zirconia bilayered restorations.
