Brief summary

The purpose of this study is to evaluate the clinical results of implant-retained mandibular overdentures in edentulous patients.

Detailed description

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.

Design outcomes

Primary

Measure	Time frame
Survival of implants	through study completion, an average of 1 year

Secondary

Measure	Time frame	Description
Gingival Bleeding on Probing	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	through study completion, an average of 1 year	Pocket depths measured around implants in millimeter (mm)
Marginal bone loss	through study completion, an average of 1 year	—

Other

Measure	Time frame	Description
patients' satisfaction	through study completion, an average of 1 year	patients' satisfaction were assessed on visual analog scales (VAS)
oral health-related quality of life	through study completion, an average of 1 year	Patients completed a 14-item Oral Health Impact Profile (OHIP-14) to assess oral health-related quality of life
