Abstract:

 


Purpose: In this study, it is aimed to compare the distribution of stress on anchorage and implants in 3-and-5-member-dental and implant supported zirconia restorations by using finite element analysis.

Material and Method: Stress distribution formed in anchorage and implants as a result of chewing forces was analyzed in dental and implant (Astra Tech Microthread Osseo Speed, Sweeden) supported models of zirconia restoration with 5-member placed on the numbers of 43, 44, 45, 46 and 47 and with 3-member placed on the number of 45, 46 and 47.  The study was performed through static nonlinear analysis with the three-dimensional finite element analysis method.  

Results: The highest and the lowest stress were respectively found on the number of 45 and 47 in 3-member dental supported model. The highest and the lowest stress in 5-membered dental-supported model were respectively found on the tooth of number 45 and on the root apex of the implant of number 43. Stress accumulation was observed in the cervical portion of the implant in implant-supported models. Stress accumulation in the tooth-supported model was found less than in implant-supported models

Conclusion: The extreme forces on the dental and implant-supported restorations with increased members can reduce survival rate of restorations in mouth. To prefer dental implants with larger diameter and longer length along with infrastructure like zirconia to design posterior implant-supported restorations can keep restorations in mouth for longer period.
