NCT02996370

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.

Outcome Measures

Primary Outcomes (6)

  • papilla fill index

    Baseline will be 1 week after cementation of the crowns.

    baseline

  • papilla fill index

    Papilla fill index will be recorded 3rd month after baseline

    3 month

  • papilla fill index

    Papilla fill index will be recorded 6th month after baseline

    6 month

  • crestal bone loss

    Crestal bone loss was measured on radiographs between baseline-3rd month.

    Change from baseline crestal bone level up to 3 months

  • crestal bone loss

    Crestal bone loss was measured on radiographs between baseline-6th month.

    Change from baseline crestal bone level up to 6 months

  • vertical distance

    Inter-implant vertical distance between the crests top-contact point was also evaluated with digital periapical radiographs.

    baseline, 3 and 6 month

Secondary Outcomes (12)

  • Probing depth

  • Modified sulcus bleeding index

    Modified sulcus bleeding index was recorded at baseline

  • Modified sulcus bleeding index

    Modified sulcus bleeding index was recorded at 3 month

  • +7 more secondary outcomes

ACTIVE COMPARATOR

In the control group second stage surgery was made using the conventional method, midcrestal technique.

Interventions

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.

Control group- midcrestal incisionTest group- ı shape incision

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)

Control group- midcrestal incisionTest group- ı shape incision

The change of probing depth between baseline, 3 and 6month. Probing depth was measured with a plastic periodontal probe (mm)

Control group- midcrestal incisionTest group- ı shape incision

Modified bleeding index was measured baseline, 3 and 6 month. Presence of bleeding on probing were performed at four sites of implants.

Control group- midcrestal incisionTest group- ı shape incision

Modified plaque index was measured baseline, 3 and 6 month. Presence of plaque index was performed at four sites of implants.
