EFFECT OF CROWN-IMPLANT (C/I) RATIO OF SHORT IMPLANTS ON PERI-IMPLANT STRESS: A FINITE ELEMENT ANALYSIS
Main Article Content
Abstract
Objectives. Purpose of this study was to evaluate the distribution of peri-implant stress with different С/I ratio( 1.5:1, 1.75:1, 2:1) according to the von Mises criterion.
Materials and methods: Stress analysis was performed using Invesalius 3.0, Rhinoceros 3D 4.0 software. Three 3D models of the mandibular segment of the bone block were developed:
- model A, a short implant C/I – 1,5:1;
- model B, a short implant C/I -1.75:1;
- model C, a short implant C/I -2:1.
Results: The results of the current study, indicate the increase in crown height showed little difference in load at the crown/implant interface with crown/implant ratios of 1.5:1, 1.75:1 and 2:1.
Conclusions: Study showed that short implantats for prosthetic rehabilitation can be considered favorable and well substantiated, C/I ratio is not so important for the effective functioning of short implants.
