“…AIPMMA is well tolerated in humans after long‐term implantation 31,32 . However, PMMA induces a nonspecific foreign‐body reaction in soft tissue and bone 33–35 . To the author's knowledge, the effects of intra‐articular AIPMMA beads have not been reported.…”

“…However, the reliability of these methods in detection of the progression of periodontal disease is still questionable. The single-crystal sapphire is a relatively new ceramic material for the dental implant and has been shown to be biocompatible and of improved mechanical strength (Kawahara, Hirabayashi & Shikita, 1980;McKinney, Koth & Steflik, 1985;Akagawa et al, 1985). Clinical use of the single-crystal sapphire endosseous implant has started not only in Japan but also in the U.S.A. and some European countries.…”

The correlation between clinical periodontal parameters and histological structure of the gingiva around a single-crystal sapphire implant has been evaluated in two volunteer subjects. The implants had functioned after 6 years as the distal abutment of implant bridges in the Kennedy class II mandible. First, clinical evaluation was performed (gingival bleeding index, crevicular fluid volume, plaque index and probing depth) of the gingiva around the implant and natural teeth abutments and then a small piece of peri-implant gingiva was excised from the lingual site of the implant of each subject for histological evaluation. The clinical evaluation using the periodontal parameter indices corresponded with the histological evaluation of the peri-implant gingiva. The result suggests that it is possible for such parameters to be used in practice for judging the success of an implant.

“…The single-crystal sapphire (Kyocera Inc., Kyoto, Japan) is a relatively new ceramic material with which the problem of mechanical strength has been significantly improved. Several investigators (Kawahara, Hirabayashi & Shikita, 1980;McKinney & Koth, 1982;McKinney, Koth & Steflik, 1982;Akagawa et al, 1985) have shown this material to be biocompatible and to possess enough strength against functional load during chewing. However, none of these studies were designed to evaluate the histological reaction of the tissues surrounding functioning implant with a superstructure.…”

Peri-implant tissues of the single-crystal sapphire implant connected with neighbouring teeth by a metal bridge-work were examined clinically, radiographically, and histologically in ten monkeys. Professional tooth cleaning was performed during the study. At 3-12 months after insertion, most of the implants were firmly connected to the surrounding tissues and peri-implant gingiva was regarded as healthy, based on various periodontal parameter scores. Destructive changes of the peri-implant bone were not found radiographically. Histologically, peri-implant gingiva was revealed to show similar structure to that of the gingiva around natural teeth. Direct bone-implant interface was observed at 3 months after insertion, while a thin loose fibrous connective tissue layer was present between bone and implant at 6 and 12 months. Such different interrelationship between bone and implant might be attributable to the difference in distribution of functional stress.
