Brief summary
To investigate the prevalence and risk factors for peri-implant disease in partially edentulous patients rehabilitated with implants supported crown or bridge so as to provide evidence for clinical prevention and control.
Detailed description
The aim of the present study is to identify the prevalence of peri-implant disease in partially edentulous subjects treated with osseointegrated implants, using clinical parameters, as well as to analyse the possible disease association with demographic, behavioural, and biological risk variables.

Exclusion criteria
* Jaw radiotherapy treatment before and after implanting.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| peri-implant disease | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Gingival Bleeding on Probing | 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 | 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 | 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. |
