영문 초록

The long-term success of any dental implant is dependent upon the optimization of stresses which occurs during oral functing and parafunction. Although there have been many studies to examine the bicomplatibilites between dental implants and living tissue, few studies have been reported on the biomechanics of dental implants. The purpose of this study was to qualitatively analyze the stress distribution of esthetic restorations in osseointegrated implants. The finite element models were Branemark Implant conventional system, EsthetiCone Abutment, Anatomic Abutment and UCLA Abutment. The Branemark implant fixtures(3.75mm in diameters, 10 mm in length) were used in 4 models. Two dimensional finite element analysis was used for this study. The softwares were Super SAP (Algor Inc.) for IBM 32 Bit Computer. The results were as follows ; 1. The stresses were concentrated at the neck of the implant in all models and the face may be closely related with the initial resorption of cortical bone at neck site. 2. In cases of Branemark implant conventional system and EsthetiCone Abutment, the stress concentrations at the base of implant were around the axis of implant, but in Anatomic Abutment and UCLA Abutment, they were diffuse around the apex of implant. 3. In maximum stress, Branemark implant conventional system was the lowest value, and UCLA Abutment was the highest. 4. In Branemark implant conventional system, EsthetiCone Abutment, and Anatomic Abutment, maximum stresses were at the neck of the implant and bone, but it was at the base of impaltn in UCLA Abutment. 5. The stresses were almost linearly propotional to the amount of load.
