THE EFFECT OF PITCH VARIATION ON MECHANICAL PROPERTIES IN THE DESIGN OF TOOTH IMPLANT
AbstractThis study provides a review of the achievements and advancements in dental technology brought about by computer-aided design and the all powerful finite element method of analysis. The scope of the review covers dental implants, jawbone surrounding the implant and the biomechanical implant and jawbone interaction [1]. The dental implant is desined by SolidWorks and analysed by ANSYS. The main objective of the study was to investigate into the stress and strain variations due to the effect of bone remodelling and healing.In this study, the stresses acting on an abutment and implant types which have three different pitch distance type were inspected. Three types of dental implants, an abutment and a representative cortical bone, cancellous bone and crown were designed. Titanium-Aluminum-Vanadium alloy was chosen for implant and abutment, alumina was chosen for crown, SolidWorks was preferred as program for design and ANSYS for analysis. Deformations, displacement vectors, von Mises stresses, principal stresses on the implant and the abutment were inspected. At the end of the study , the results of the analyses showed that changing the pitch distance affects the analysis results. In this study, our aim was to make an appropriate choice from three different types of implants. An ideal choice should have minimum stresses. According to the results of the analyses, the implant 0,75 mm pitch V-type threaded implant should be chosen.
