Trial 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.

About this study

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • papilla fill indexOther

    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.

  • crestal bone lossOther

    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)

  • probing depthOther

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

  • Modified sulcus bleeding indexOther

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

    Measured: 3 month

  3. papilla fill index

    Papilla fill index will be recorded 6th month after baseline

    Measured: 6 month

  4. crestal bone loss

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

    Measured: Change from baseline crestal bone level up to 3 months

  5. crestal bone loss

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

    Measured: Change from baseline crestal bone level up to 6 months

Questions about this trial

What is this clinical trial studying?

A study testing papilla fill index, crestal bone loss and probing depth in people with Tooth Loss and Bone Loss, run by Ege University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

papilla fill index (time frame: baseline). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2016.
