no peri-implant disease
The subjects who did not suffer from peri-implant disease.
The subjects who suffered from peri-implant disease.
- peri-implant disease [ Time Frame: at the 5 years after prosthetic loading. ]Peri-implant disease includes Peri-implant mucositis and Peri-implantitis.Peri-implant mucositis: BoP/suppuration but no detectable bone loss. Peri-implantitis: BoP/suppuration and bone loss >2 mm.
- Gingival Bleeding on Probing [ Time Frame: at the first day,6 months 1,3 and 5 years after prosthetic loading. ]Gingival bleeding on probing (BOP) using the modified sulcus bleeding index for implants. Scale equals 0 = No bleeding when periodontal probe is passed along the gingival margin;1 = Isolated bleeding spots visible;2 = Blood forms a confluent red line on the gingival margin;3 = Heavy or profuse bleeding.
- Pocket depths [ Time Frame: at the first day,6 months 1,3 and 5 years after prosthetic loading. ]PD will be measured from the free gingival margin to the base of the pocket and will be recorded in whole millimeters (mm).
- Marginal bone loss [ Time Frame: at the first day,6 months 1,3 and 5 years after prosthetic loading. ]Marginal bone loss will be assessed by periapical radiographs taken with the paralleling technique.
