Statement of problem: Standard type of ITI solid implant model placed in the 6.2mm thick jaw bone was axisymmetrically modelled for a series of finite element stress analyses. Purpose: The purpose of this study was to investigate the influences of the insertion depth on the cervical bone stresses. Material and methods: As implants are tend to be inserted deeper than the company recommended insertion depth, five different insertion depths were supposed for the present study. i.e. 0, 0.7, 1.4, 2.1 and 2.8mm of submersion depth. Course of the osseointegration process at the bone/implant interfaces were taken into consideration too. To simulate the characteristics of osseointegration process, three different stages of the bone/implant interface model were implemented. Bone at the cervical region of implant was the area of concern where the higher level of stress were likely to take place. Results and Conclusions: Under vertical load of 50N significant differences in the stress were observed due to the difference in the insertion depth. Rather slightly different stress level, however, was monitored at the cortical bone as a function of the osseointegration stage.
