Summary

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.

Detailed description

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.

Conditions

• Tooth Loss
• Bone Loss

Interventions

Type	Name	Description
OTHER	papilla fill index	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.
OTHER	crestal bone loss	Crestal bone loss was measured on digital radiographs at baseline, 3 and 6 month with a Java program me (Image-J 3.0 NIH, Bethesda, USA)
OTHER	probing depth	The change of probing depth between baseline, 3 and 6month. Probing depth was measured with a plastic periodontal probe (mm)
OTHER	Modified sulcus bleeding index	Modified bleeding index was measured baseline, 3 and 6 month. Presence of bleeding on probing were performed at four sites of implants.
OTHER	Modified plaque index	Modified plaque index was measured baseline, 3 and 6 month. Presence of plaque index was performed at four sites of implants.
