Abstract
Background
A dental implant is a metal component that is inserted into the root of a missing tooth to serve as a support for a prosthetic crown. A splinted implant is a simply supported bridge structure in which the two adjacent implants have a direct connection by means of a crown, whereas a non-splinted implant does not have any connection with other adjacent implants. In the present study splinted implants of molar and premolar crown have been used. The aim of the present study is to compare stress distribution in bone with varying crown to height ratios.
Methods
The crown-to-implant (CI) ratios of 1:1, 1.5:1, 2:1, and 2.5:1 was selected. On the crown surface, two separate loads of 75 N and 100 N were applied vertically and obliquely at 30° angle. The stress analysis was carried out to obtain the best CI ratio for splinted implants.
Results
The jawbone was subjected to similar stress under vertical loading in all four CI ratio models whereas, at 30° oblique loading, a significant rise in stress was observed in all four ratios.
Conclusion
Dental models with a smaller crown-to-implant ratio were seen to be more effective as lower stress was developed in them.
