S16 The Journal of Indian Prosthodontic Society | Volume 20 | Supplement 1 | December 2020 Introduction: Edentulism is the major problem in the elderly population. Loss of retention and stability of the lower denture can be overcome by implants to improve their masticatory efficiency, and quality of life. So, the aim of this study was to evaluate and compare the masticatory efficiency of single and double implant retained overdenture and assess their oral health related quality of life by questionnaire method. Methodology: Twenty edentulous patients with inclusion and exclusion criteria divided into two groups, provided Conventional complete denture (CCD) to all patients. Objective evaluation (surface EMG) was done after 3 months, followed by placement of implantsGroup I (SIOD) with single implant and group II with two implants (DIOD). Delayed loading was followed. Surface EMG evaluation was done again after 3 months usage of dentures. Subjective evaluation was done using OHIP 20 questionnaire before and after implant placement. Result: Statistically analysis of EMG results found that there was statistically significant difference (p<0.05) between CCD and SIOD, CCD and DIOD, DIOD and SIOD respectively. In Subjective evaluation by questionnaire method, though there was significant difference found between CCD ad SIOD, CCD and DIOD respectively, there was no statistical difference (p > 0.05) between SIOD and DIOD. Conclusion: This study revealed that single implant retained overdenture improved masticatory efficiency and the patient satisfaction was similar to both SIOD and DIOD respectively. So this study concluded that single implant may be good alternative to two implant retained overdenture in patients who cannot afford to two implants DOI: 10.4103/0972-4052.306339 Digital dental tapemagical tape Dr. Prajna Prakash Shetty Rajarajeswari Dental College & Hospital, Bangalore Introduction: Vertical dimension of occlusion (VDO) has been defined by glossary of prosthodontic terms as the distance between two selected anatomic or marked points (usually one on the tip of the nose and the other on the chin) when in maximal intercuspal position. Inaccurate vertical dimension recording can result in an array of problems. It can cause a multitude of adverse effects in aesthetics, temporomandibular joints, functional efficiency, and masticatory muscles disorders and affect the facial expression of the individual.

S38 The Journal of Indian Prosthodontic Society | Volume 20 | Supplement 1 | December 2020 Introduction: Occlusion is considered to be the most important discipline for the maximum possible efficiency of prosthesis replacing missing teeth or restoration. 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.

The temporomandibular joint (TMJ) is one of the primary components of the complex masticatory system. Any disturbance in the joint due to congenital or acquired causes such as trauma, pathology, or functional disturbance affects the masticatory system. This case report highlights the management of condylar hypoplasia due to trauma by forceps delivery which led to TMJ dysfunction and chronic disc displacement without reduction. A combination of stabilization appliance and arthrocentesis using platelet-rich plasma along with patient education has been proved effective for the conservative management of patients with chronic disc displacement and TMJ dysfunction.

Aim: The aim of this study was to compare and evaluate the efficacy of ViscoStat clear, Vasozine, and Racegel (with and without cord) with respect to the amount of lateral gingival displacement produced by them. Settings and Design: Comparative - In vivo study. Material and Methods: Thirty consented volunteers were selected in the age group of 18–22 years. Maxillary right first premolar and lateral incisor and maxillary left central incisor and canine were selected for each individual. A composite resin standard reference point was made two millimeters below the gingival margin on the midsection of the labial surface of each tooth. By simple random sampling, the agents (ViscoStat clear, Vasozine, and Racegel with cord and Racegel without cord) were used for gingival displacement on each of the selected teeth. Pre- and postgingival displacement impressions were made with medium-body polyvinyl siloxane impression material. Three-millimeter thick buccolingual slice sections were obtained of the models and measured under a stereo microscope (×20 magnification), and the amount of displacement was calculated. Statistical Analysis used: The Kruskal–Wallis test and the Mann–Whitney U-test were used for comparison between the amounts of gingival displacement produced by them. Results: Mean displacement produced (in mm2) by Racegel with cord, tetrahydrozoline, ViscoStat clear, and Racegel is 0.2256, 0.2158, 0.2069, and 0.1414, respectively. Conclusions: The largest mean gingival displacement was produced by Racegel with cord (0.2256 mm2) and lowest by Racegel without cord (0.1414 mm2). There was no significant statistical difference in the amount of gingival displacement produced between the four agents.

Aim: The complete denture fracture of denture may ruin the routine life of an edentulous patient. The aim of the present study was to propose and evaluate a new classification system for denture fractures. Settings and Design: Cross sectional -Survey. Materials and Methods: Ten dental laboratories in Delhi and the National Capital Region participated in the study for 2 years. The accurate assessment of fractured dentures received in the laboratories for repairs was done. A questionnaire with complete information along with photographs was used to classify the denture fracture. Statistical Analysis Used: Percentage (proportion) statistical test. Results: Out of 620 dentures, 164 (94 maxillary and 70 mandibular) were found with previous repair, soft liners, metal frame, or wire reinforcements which were excluded from the study. In the present study, 456 dentures were considered (256 maxillary and 200 mandibular). Class I fracture (midline) was the most common in both maxillary and mandibular dentures (46.87% in maxillary and 61% in mandibular) with high significance (P < 0.001). Class II and Class V were the second most common pattern of fracture in mandibular and maxillary dentures, respectively. There was no single case of Class III fracture for the mandibular dentures, and Class IV was the least common among the maxillary dentures. Conclusions: This study encourages further clinical studies for validation and reliability evaluation of proposed new classification system.

Aim: The objective of research was to evaluate the shear bond strength of two commercially available intraoral porcelain repair systems, Clearfil repair system (Kuraray) and P and R repair system (Shofu) for repairing cohesive and adhesive fracture in metal-ceramic restorations. Settings and Design: In vivo – comparative study. Materials and Methods: Ninety samples of Nickel–Chromium metal discs were fabricated. Each disc was veneered with 2 mm thickness of ceramic material using custom made metal jig. Samples were divided into control (Group I n = 10) and two test groups (Group II n = 40 and Group III n = 40). Adhesive and cohesive fractures were created in test group samples, Group II (Ceramic substrate or cohesive defect) and Group III (metal substrate or adhesive defect). The samples of ceramic substrate (Group II) and metal substrate (Group III) were further subdivided into A and B containing 20 samples each according to the repair material used (A; Clearfil porcelain repair system and B; P and R porcelain repair system). All specimens were subjected to a standard shear load in the UTM until fracture occurred. Data were analyzed using one-way analysis of variance and post hoc Bonferroni test. Statistical Analysis used: One-way analysis of variance (ANOVA) and post hoc Bonferroni test. Results: Clearfil repair system showed significantly higher shear bond strength value (29.16 Mpa) as compared to P and R repair system (27.23 Mpa) for cohesive fractures. Whereas if compared for repairing adhesive fractures P and R repair system had significantly higher shear bond strength values (26.59 Mpa) than Clearfil repair system (25.74 Mpa). Conclusions: From the present study, it was be concluded that for cohesive fracture Clearfil repair system is a better material and for adhesive fractures P and R repair material gives better results.

Sehgal","doi":"10.4103/jips.jips_120_19","DOIUrl":"https://doi.org/10.4103/jips.jips_120_19","url":null,"abstract":"Aim: The objective of research was to evaluate the shear bond strength of two commercially available intraoral porcelain repair systems, Clearfil repair system (Kuraray) and P and R repair system (Shofu) for repairing cohesive and adhesive fracture in metal-ceramic restorations. Settings and Design: In vivo – comparative study. Materials and Methods: Ninety samples of Nickel–Chromium metal discs were fabricated. Each disc was veneered with 2 mm thickness of ceramic material using custom made metal jig. Samples were divided into control (Group I n = 10) and two test groups (Group II n = 40 and Group III n = 40). Adhesive and cohesive fractures were created in test group samples, Group II (Ceramic substrate or cohesive defect) and Group III (metal substrate or adhesive defect). The samples of ceramic substrate (Group II) and metal substrate (Group III) were further subdivided into A and B containing 20 samples each according to the repair material used (A; Clearfil porcelain repair system and B; P and R porcelain repair system). All specimens were subjected to a standard shear load in the UTM until fracture occurred. Data were analyzed using one-way analysis of variance and post hoc Bonferroni test. Statistical Analysis used: One-way analysis of variance (ANOVA) and post hoc Bonferroni test. Results: Clearfil repair system showed significantly higher shear bond strength value (29.16 Mpa) as compared to P and R repair system (27.23 Mpa) for cohesive fractures. Whereas if compared for repairing adhesive fractures P and R repair system had significantly higher shear bond strength values (26.59 Mpa) than Clearfil repair system (25.74 Mpa). Conclusions: From the present study, it was be concluded that for cohesive fracture Clearfil repair system is a better material and for adhesive fractures P and R repair material gives better results.","PeriodicalId":22708,"journal":{"name":"The Journal of the Indian Prosthodontic Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90720603","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}

Literature has proved that implant-retained overdenture is one of the best prosthetic options in the rehabilitation of complete edentulism. Tissue-supported implant-retained overdentures have been an appropriate treatment modality for atrophic mandibular ridges. In this case report, the patient presented with Class I maxillomandibular relationship and Class II Prosthodontic Diagnostic Index. The patient was concerned about esthetics as well as the retention of the lower denture. Taking into consideration the above concerns, an implant-retained mandibular overdenture was the chosen treatment modality. There are numerous attachment systems that have been used to improve the retention, stability, and support of implant-retained overdenture. Every attachment system has its own set of advantages. The OT Equator is a new line of low-profile attachment which is a radically modified OT-CAP Normo. The rationale for using this attachment is that it is considered the smallest attachment system available with the least overall dimension. It is a resilient and self-aligning attachment system which can be used in limited inter-arch space situation. OT equator derives its name from the OT Dental Laboratory (Bologna, Italy) used as a brand name. Considering these advantages, this was the chosen attachment and proved beneficial in terms of both patient satisfaction and the overall success of the treatment.
文献证明种植固位覆盖义齿是全牙义齿修复的最佳选择之一。组织支持种植保留覆盖义齿是治疗萎缩下颌骨嵴的一种合适的治疗方式。在本病例报告中，患者表现为I类上颌骨关系和II类修复诊断指数。患者担心美观以及下义齿的固位。考虑到以上问题，选择种植保留下颌覆盖义齿作为治疗方式。有许多附着系统已被用于改善种植固位覆盖义齿的固位、稳定性和支持。每一种依恋系统都有自己的优点。OT赤道是一种新的低姿态附件，这是一个彻底修改OT- cap Normo。使用此附件的基本原理是，它被认为是最小的附件系统，具有最小的总体尺寸。它是一种弹性自对准的附着系统，可用于有限的拱间空间。奥特赤道源于奥特牙科实验室(博洛尼亚，意大利)作为一个品牌名称。考虑到这些优点，这是被选择的附件，并且在患者满意度和治疗的整体成功方面证明是有益的。
