[Maintenance and osseointegrated implants].

Plaque, which is a major etiologic factor in human periodontal disease, also can be found around dental implant fixtures. The authors compare peri-implant disease to periodontitis in order to attempt to define more precisely the principles of maintenance therapy.

Bone formation in tricalcium phosphate-filled periodontal intrabony lesions. Histological observations in humans.

The capacity of a tricalcium phosphate (TCP) ceramic to promote bone formation after grafting in intrabony defects was studied in humans. Five biopsies were collected from 4 patients during reentry surgery 16 to 40 months after implantation. They were processed without demineralization for histological examination. In the less mature samples, the grafted material was surrounded by a highly fibrous, highly cellular, and poorly vascularized connective tissue. Howship's lacuna-like cavities were clearly visible at the surface of the material. They contained resorbing mononuclear phagocytes. At a more mature stage, TCP granules were embedded in an acellular fibrous material which underwent mineralization from the medullary spaces towards the granules. The bone formed was subsequently remodeled. The implanted material itself was progressively modified. It first acquired the staining appearance of bone. After its structure became loose and vacuolated, it was invaded by cells and vessels. The present data indicate that TCP has osteogenic potential and is subject to degradation. Unlike in experimental wounds, these processes are of long duration in human defects.

[Bleeding on probing. Significance--consequences].

Bleeding on probing is one of the techniques for evaluation of the periodontal pocket tissues condition. Bleeding, leading sign of inflammation inside the connective tissue, is a critical factor for pocket depth measurements, and with other variable factors prevents making reproducible measurements. With the concept of periodontal disease with asynchronous bursts of activity and period of remission, has appeared the necessity to determine and even to predict the presence of destructive activity just as it occurs in a particular site in order to set up a selective therapy. Many authors investigated for a correlation between destructive activity and bleeding on probing. At the present time, the development of manual or electronic probes provides a useful diagnostic aid for the clinician in daily practice as well as the researcher in longitudinal studies.
