Abstract
There have been relatively few objective evaluations of endosteal implants. In 1986 we reported objective clinical and radiographic evaluations of endosteal implants(H. Abe et al:J. Tokyo. Wom.Med. Coll.56,547～561,1986).
In our department between January 1984 and November 1986,80 titanium(Ti)bladevent implants were inserted into maxilla and mandible. The present paper describes the clinical and radiographic evaluation of 41 cases which could be followed up formore than 3 years. The evaluation was performed by examining the gingival pocket at the implantneck, gingival health, tooth mobility and bone loss.After the evaluation, the cases were classified into 4 types:Class 1(good), Class 2(fair), Class 3(removal necessary), Class 4(removed).
It was found that 29 cases(70.7%)belonged to Class 1,10(24.4%)to Class 2, none to Class 3 and 2(4.9%) to Class 4. These results indicate that Ti-bladevent implants which were followed up for 3 years were associated with good periodontal health and were functional.
