简要总结
To evaluate a cross-shaped incision technique to thick-gingiva and thin-gingiva patients treated with implant-supported fixed prosthesis.
详细描述
Objective
To evaluate a cross-shaped incision technique to thick-gingiva and thin-gingiva patients treated with implant-supported fixed prosthesis. Methods and Materials: 55 patients received cross-shaped incision were assigned into thick-gingiva group (29 cases) and thin-gingiva group (26 cases). Follow-up examination was carried out 3 and 12 months after final restoration. Clinical and radiographic evaluation including gingival papilla height, modified plaque index, modified sulcus bleeding index, periodontal depth, and crestal marginal bone level were utilized.

结局指标
主要结局
Modified Plaque Index (mPI)
时间窗: Between June 2018 and June 2020.
plaque accumulation around the marginal peri-implant tissue was assessed
Probing Depth (PD, in millimeters)
时间窗: Between June 2018 and June 2020.
PD was assessed at the mid-buccal, mid-oral, mesial and distal aspects of each implant with a standard periodontal probe, and final value was determined by the average of four aspects
Gingival margin level
时间窗: Between June 2018 and June 2020.
Gingival margin level was assessed by calculating the vertical distance between the most apical point of gingival margin at the buccal aspect of the crown and line connecting the peak of the adjacent mesial and distal natural teeth
papilla height
时间窗: Between June 2018 and June 2020.
Presence/absence of papilla height was assessed visually
Modified Sulcus Bleeding Index
时间窗: Between June 2018 and June 2020.
the bleeding tendency of the marginal peri-implant tissue was evaluated
次要结局
- first bone-implant contact (fBIC) and implant shoulder (IS)(Between June 2018 and June 2020.)
