SYNOPSIS
Few studies have investigated the bone healing of the tooth extraction socket in type 2 diabetes. The purpose of this study was to evaluate the process of bone healing of mandibular incisor extraction sockets after inserting a titanium alloy screw in type 2 diabetes model rats.
Rats were divided into type 2 diabetes model animal and a control group. Titanium alloy (Ti-6Al-4V) screws were placed into the mandibular incisor extraction sockets. At 3, 6, 9 and 12 weeks post-operation, biomechanical and histological observations were performed.
As a result, removal torque strengths as biomechanical evaluation were not significant between the two groups.
These study results demonstrated that type 2 diabetes has slightly differences on bone healing after tooth extraction without surrounding environment factor.
