Abstract

Purpose/objectives: The aim of the research was to develop a model that accurately represents an Aramany class II defect and its obturator prostheses fabricated with Cobalt Chromium alloy & Titanium alloy to compare the deflection and the stress distribution in the rehabilitated area. Methods: Aramany class II defect and the obturator prostheses was generated geometrically utilizing ANSYS 14.5, both overlaid on each other to impressionist prostheses and the maxilla as one element. Meshing of models was carried out utilizing HYPERMESH software & materialistic properties were assigned. The 120 N load was constituted on the teeth in different directions. Results: The stress distribution & deflection executed by ANSYS provided results that enabled the tracing of Von Mises stress and deflection field in the form of color veiled bands with standards in Mega Pascal (MPa). Conclusion: The study shows that Von Mises stresses are higher for the frame work fabricated with cobalt chromium alloy compared to Titanium alloy. The framework made of titanium alloy showed more deflection than cobalt chromium alloy. Clinical implications: 3D FEA can be performed on a computer without putting any stress on the human body from technical materials, which is especially difficult for maxillectomy patients. Keywords: Aramany Class II defect, Cobalt chromium alloy, Titanium alloy, Finite element analysis, Von Mises stresses

Abstract

Background: COVID-19 has become a crisis across the country these days, which likewise changed living of individual to entity contact and its spread. There the presentation of Teledentistry will be the solitary solution that will have the option to treat patients quickly and expertly. Aim: The current study aims to assess the awareness of dental professionals towards teledentistry during COVID-19 crisis in India. Methods: A cross-sectional descriptive survey was conceded on over all 142 dentists. A self-organized, close-ended questionnaire containing 20 questions was appropriately assembled and distributed. Data collected from the survey was examined in terms of frequency (yes/no). One Way Anova test was used to exemplify statistical variances and result came as significant at p < 0.05. Results: The responses from specialist dental professionals (with or without practicing) responded (57%) and dentist working in a private sector (68%) having clinical experience of about 5-10 years (36%). Conclusion: Dentists were well aware of this advanced technique and due to feasibility, most of them were ready to practice it in future.
