Surgical Tooth Implants, Combat and Field.
Abstract
Long term implant studies involving high density alumina tooth roots have been undertaken in baboons using single root elliptical and rectangular design with serrations designed for maximal stress distribution. The roots are produced by cutting on a computer controlled milling machine. This technique allows for sizes and shape flexibility, and stress distribution area maximization. Both fresh extraction sites and edentulous sites have been used. The 'success' rate for roots once they are ingrown and in function is approximately 90 percent. Most failures occur during this initial 2 to 3 month ingrowth period. This initial period has been found to be the most crucial period for implant 'success.' Previously the loss was approximately 40 percent during the ingrowth period in baboons. However, during this project year, the failure rate has been significantly reduced to approximately a 5% loss rate.
