The purpose of this study was to clarify the mechanical characteristics of dental implants using Bioactive Glass.
The value of the load bearing strength determined by the breaking strength test was used as a base to observe and analyze the implant through the 3-D Finite Element Method. These results were then compared to the analytical results from an implant model and evaluated.
Results showed that fracturing of dental implants or implants coming loose was solely dependent upon where the load was applied, load angle, and direction of load application.
Placement of the dental implant is determined by taking into consideration the direction of the occlusal force.The direction of load bearing in relation to occlusal contact on the outer oblique plane of the cusp and midportion of the occlusal plane was found to be desirable between 90°to 135° and 60°Cto 120°C, respectively.
