Newly tailored artificial roots made of dense hydroxyapatite were applied clinically and artificial roots of connective tissue attachment type were used. The subjects were healthy adults who visited our hospital. They consisted of 16 males and 20 females, from 27 to 65 years old, with partially edentulous dentition sites. The follow-up duration was 6～23 months. The clinical evaluation was made by macroscopic findings on peripheral gingiva of the artificial root, radiographic findings, and observation of the functional state in mastication. Among the cases treated, there were four cases in which reimplantation were made, after which satisfactory results were obtained.
Adhesion to the epithelium of Hydroxyapatite (HAP) is so superior that gingival infection can be satisfactorily prevented through attention to oral hygiene as well as avoidance of postoperative occlusal pressure on the roots. However, for success of the above-mentioned procedure, attention must be paid to various interoperative and postoperative treatments so as to avoid infection around artificial roots.
