Brief 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.
Interventions
OTHERpapilla 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.
OTHERcrestal 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)
OTHERprobing depth
The change of probing depth between baseline, 3 and 6month. Probing depth was measured with a plastic periodontal probe (mm)
OTHERModified 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.
OTHERModified plaque index
Modified plaque index was measured baseline, 3 and 6 month. Presence of plaque index was performed at four sites of implants.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| papilla fill index | baseline | Baseline will be 1 week after cementation of the crowns. |
| crestal bone loss | Change from baseline crestal bone level up to 3 months | Crestal bone loss was measured on radiographs between baseline-3rd month. |
| vertical distance | baseline, 3 and 6 month | Inter-implant vertical distance between the crests top-contact point was also evaluated with digital periapical radiographs. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Probing depth | baseline | The level of probing depth at baseline. Probing depth was measured with a plastic periodontal probe. |
| Keratinized tissue level | Keratinized tissue level was recorded at baseline | Keratinized tissue level measured with a plastic periodontal probe |
| Modified sulcus bleeding index | Modified sulcus bleeding index was recorded at baseline | Modified sulcus bleeding index was recorded at four sites of implants after 10 sec. of probing. |
| Modified plaque index | Modified plaque index was recorded at baseline | The dichotomous presence of supra gingival plaque was recorded at four sites of implants |
