Abstract: Background and AIM:
Implant supported prosthesis has become a routine dental treatment for restoring a natural or unnatural tooth loss. To achieve the best outcome, careful consideration of technical and biomechanical parameters, is essential. This study aimed to evaluate the present outlook and opinions regarding stress distribution in implant with parallel, mesial and lingual inclination using finite element analysis (FEM).
Materials & Methods: Thorough exploration of the existing pool of biomedical information was attempted. Significant and relevant studies were filtered out to outline certain concrete inferences. Data exploration was completed using user friendly interfaces of search engines, scholarly search bibliographic databases and textbooks were searched until July 2018 using MeSH (Medical Subject Headings) based keywords such as “stress distribution”, “posterior mandibular”, “edentulous bone”, “lingual inclination”. The search was limited to original researches, reviews, systematic researches and meta-analyses in various dental journals published over the last 38 years in English language only. A total of 125 articles were identified however after examining the titles and abstracts, this number was finally condensed to 55 articles. For the ease of categorization, articles were divided into four groups.
Statistical Analysis & Results: Data compilation was done in a logical manner. All tabulations and excel charts were sent for statistical analysis using statistical software Statistical Package for the Social Sciences. The resulting data was subjected to relevant statistical tests to obtain p values, mean, standard deviation, chi-square test, standard error and 95% CI.
Conclusion: Authors have concluded that none of the screened studies has precisely shown the intricate relations of stress distribution and their changing angulations. Hence, the need of hour is to have some long term reliable studies which possibly will define the exact role of various implant angulations and stress distribution. Perhaps it will also build more comprehensive understanding in this perspective.
