Abstract

Introduction:

Finite element analysis (FEA) is a widely used method to evaluate the biomechanical aspects of dental implants; however, its clinical reliability depends on experimental validation. With the introduction of three-dimensional (3D) printing, customized implants offer potential improvements in stress distribution. The study was done to evaluate and compare stress distribution in conventional and 3D-printed implant models using FEA.

Materials and Methods:

An experimental research was done with a sample size of 480 observations. 3D implant models were developed and analyzed using ANSYS Workbench under simulated loading conditions (100–150 N). An in vitro validation was performed using strain gauges under mechanical loading. Statistical analysis was conducted using IBM SPSS version 25.0 with P < 0.05.

Results:

The 3D-printed implant models demonstrated significantly lower stress values across all regions, particularly at the crestal bone. In vitro strain values were also reduced in the 3D group. A strong positive correlation was found between FEA and experimental findings ( r = 0.872, P = 0.001).

Conclusion:

3D-printed implants exhibit improved biomechanical performance with reduced stress concentration and strong validation of FEA outcomes.
