Background: Biomechanics of an implant-supported prosthesis play a key role in the success or failure of rehabilitation of missing teeth. This study aimed to analyze biomechanical factors, such as an implant design and prosthesis design for a single implant-supported prosthesis. An in-vitro strain gauge analysis and finite element analysis were performed to assess different implant thread shapes and prosthesis retention modes for their strain-producing property in the peri-implant region of bone. Methodology: Four study models were prepared. Two models were fitted with Bio Horizon Tapered-Pro implants having predominant buttress-shaped threads (BT) and then two models were fitted with Grande Morse Neo Dent implants having trapezoid-shaped threads (TT). Each design was used with two types of retention modes for prostheses, BP-C and TT-C for cement-retained prostheses and similarly BT-S and TT-S for screw-retained prostheses. The strain gauges were bonded to the models and connected to a strain meter. Using an opposing porcelain fused to a metal prosthesis, a combined (axial and non-axial) load of 50–300 N at a strain rate of 0.95 mm/s was applied stepwise to each prosthesis. The strain values were recorded, and the collected data were organized and analyzed using SPSS version 22. For the finite element analysis, four 3-D models were designed. The bone, dental implants, and prostheses for each group were designed using Solid Works. A static, linear simulation was conducted in Ansys software. Results and discussion: The strain values recorded were all less than 3000μɛ and within the physiological loading zone as per Frost’s theory. Statistically significant differences were found between all groups with p-values |
