Abstract
A study was undertaken to evaluate the ionβbeam texturing of aluminum oxide as a means of providing a surface which will produce a biological prosthetic attachment. A wafflelike pattern of surface contours 150 Γ 75 Γ 35 ΞΌm deep was produced on cylindrical dental implants. The textured surfaces were compared to the as received surfaces in adult mongrel dogs. Implants were inserted into surgically modified healed extraction sites and were left in place for six months. Postβsacrifice mechanical testing was used to quantify the displacement response of the implants.
The clinical, radiographic and mechanical testing evaluations did not reveal any statistically significant differences in the performance of the dental implants. However, it was observed that anatomical site and mandibular geometry with respect to implant size play a significant role in affecting implant retention.

## Abstract A threeβdimensional finite element analysis (FEA) has been used to determine the effect of implant elastic modulus on stresses in tissues around LTI carbon and aluminium oxide dental implants. The finite element model was constructed to represent a baboon mandible containing a blade typ
