Assessment of Viewpoint and Opinions about Stress Distribution in Titanium Implants at Different Angulations Using Finite Element Analysis: An Original Research Study

Abstract

Abstract
Background and Aim: Dental implant has become popular nowadays however there are still some
realistic issues are associated with it. Most of the failures of implants are seen after the loading of
implants. This could be due to the uneven distribution of forces. Therefore, this study was conducted
to evaluate the current viewpoint and opinions regarding stress distribution in Titanium implant with
different inclination using finite element analysis.
Materials & Methods: This study was conducted on the results of pioneer researches in the last few
decayed those published in literature worldwide. Authors included only the finite element analysis
studied those performed for mandibular jaw only. Internet based tools like search engines, intellectual
search bibliographic databases and textbooks were used. Authors explored the data until June 2024
using keywords and included 79 papers. Group I was having searches of 1975-1987. Group II was
having searches of 1988-2000. Group III was having searches of 2001-2012 and group IV was having
the search results of year 2013 onwards. Availability of data about Finite Element Analysis study per
year, Finite Element Analysis study conducted for different angulations, their frequency, and number
of studies attempted and their collective conclusions were taken into considerations to formulate the
results.
Statistical Analysis & Results: Statistical analysis was completed by SPSS software. Group I
confirmed only 4 studies and the p value was not significant with Chi Square Test (Pearson χ2) value
0.01. Group II had 14 studies and the p value was not significant with Chi Square Test (Pearson χ2)
value 0.22. The level of significance (p value) was highly significant for the group II and III. Mean
value was maximum noted for the 1975-1987, it was 0.938. It was minimum for 1988-2000, it was
0.582. Standard deviation was maximum noted for the 1975-1987, it was 0.839. It was minimum for
2013-, it was 0.103.
Conclusion: Within the limitations of the study, authors confirmed that there was a clear rising
pattern of the Finite Element Modeling studies conducted on the mandible. However, most of the
studies did not consider in detail about the possible effects of the changing angulations of implants on
stress transfer. Authors also presume some long term future studies to be conducted to validate and
confirm our results.
