Abstract

Bone quality and quantity distribution of 415 jaws in 371 dental implant patients who were treated in Implant Clinic, Hospital of Nippon Dental University were studied following the classification proposed by Lekholm and Zarb(1985);the following results were obtained.<br/> 1. The cases of bone quality “1” were significantly less in number than other bone qualities.<br/> 2.The anterior edentulism(incisor/canine)showed significantly less soft in quality and significantly less massive in quantity than posterior (premolar/molar)edentulism.<br/> 3.The maxillae showed significantly less hard in quality and significantly more massive in quantity than the mandibles.<br/> 4.Females showed significantly less hard in quality and significantly less massive in quantity than males.<br/> 5. Bone quantity showed the inclination to reduce as the age of patients increased.<br/> 6. The second decade patients(youngest patients in this study)showed significantly less hard in bone quality than others.<br/>
