Official Title: Clinical Results of Implant-retained Mandibular Overdentures in Edentulous Patients: A 5-year Retrospective Study
Brief Summary: The purpose of this study is to evaluate the clinical results of implant-retained mandibular overdentures in edentulous patients.
Detailed Summary: The survival of implants,condition of the peri-implant soft tissue were evaluated. And patients' perceptions regarding the outcome were assessed on visual analog scales (VAS), oral health impact profile-14 (OHIP) and semantic differential scale questionnaires.

Current Primary Outcome: Survival of implants [ Time Frame: through study completion, an average of 1 year ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Gingival Bleeding on Probing [ Time Frame: through study completion, an average of 1 year ]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: through study completion, an average of 1 year ]Pocket depths measured around implants in millimeter (mm)
- Marginal bone loss [ Time Frame: through study completion, an average of 1 year ]
Original Secondary Outcome: Same as current
