Orthodontic Implant Stability and Its Dependency on Screw Diameter and Insertion Depth: A Comprehensive Study.
Objective: This study delves into the stability of orthodontic implants with a specific focus on how screw diameter and insertion depth impact the insertion torque, oral vitality, and pain perception. Material and Methods: A cohort of 64 patients participated in this comprehensive investigation. Orthodontic implants were meticulously positioned at varying depths after predrilling holes of differing diameters. The insertion torque was meticulously measured to rigorously assess implant stability. A subset of these implants served as indicators for quantifying the necessary adjustments to accommodate local variations in bone quality. Results: The findings of this study uncovered a profound correlation between insertion torque and stability scores, as well as their implications for oral vitality and pain perception (p<0.001). Notably, both insertion depth and the diameter of the predrilled holes demonstrated distinct influences on the measured insertion torque. Conclusion: Heightened insertion depths yielded increased insertion torque, thereby enhancing implant stability. Conversely, larger predrilled whole diameters led to a reduced requirement for insertion torque. This equilibrium between these variables proved instrumental in preserving oral vitality and maintaining consistent levels of patient comfort..
