Stress Distribution in Dental Implants under Occlusal Forces – A Digital Simulation.

Abstract

Aim and objectives: To analyze implant mechanics under loading using Finite Element Analysis (FEA) to assess micro-movements, identify failure points, and optimize design for improved clinical outcomes.

Materials and methods: A numerical simulation of mechanical loading on a prosthetic abutment attached to a dental implant was conducted using ANSYS R18.2 Academic®. Measurements, material specifications, and photographs were analyzed to model the implant system with a 6-degree conical connection.

Results: Stress analysis under vertical and oblique forces showed all values within permissible titanium alloy limits. Vertical forces led to uniform stress distribution, while oblique forces caused asymmetric stress with localized detachment tendencies.

Conclusions: Masticatory forces impact implant stress and may contribute to microleakage, highlighting the need for patient-specific prosthetic alignment.
