简要总结
Regenerating a predictable inter-implant papilla is the most complex and challenging aspect of implant dentistry. The aim of the study was to compare the efficacy of I shaped incision technique and conventional midcrestal incision technique for interimplant papilla reconstruction in a 6 month clinical trial.
详细描述
A total of 40 implants were placed in 12 patients. Groups were determined at second stage surgery, I shape technique used in test group and mid-crestal technique used in control group. The clinical parameters, including modified plaque index, modified sulcus bleeding index, probing depth, keratinized tissue level were recorded baseline, 3 and 6 month. The vertical distance between the crests top-contact point was evaluated with digital periapical radiographs at baseline 3 and 6 month. Also the clinical photographs were taken baseline, 3 and 6 month. Two T shaped full-round hexagonal straight filaments, each 5 mm, were used in the taking of standardized images. With these images the ratio of the papilla area in proportion to the embrasure area and the papilla classification was measured. Non-parametric test were used for statistically analysis.

结局指标
主要结局
papilla fill index
时间窗: 6 month
Papilla fill index will be recorded 6th month after baseline
crestal bone loss
时间窗: Change from baseline crestal bone level up to 6 months
Crestal bone loss was measured on radiographs between baseline-6th month.
vertical distance
时间窗: baseline, 3 and 6 month
Inter-implant vertical distance between the crests top-contact point was also evaluated with digital periapical radiographs.
