What You Need to Know Before You Apply

What is the purpose of this trial?

The objective of the present randomized clinical trial will be to compare two surgical methods of treating peri-implantitis. This study will determine if surgical debridement of peri-implantitis bone defects, including air decontamination of implant surfaces, in combination with the placement of a bone graft, differs in treatment outcomes compared to placing the same bone graft material with a resorbable collagen membrane placed over the bone graft.

Will I have to stop taking my current medications?

If you are taking corticosteroids, IV bisphosphonates, immunosuppressants, or medications with side effects of gingival growth, you may need to stop as these could affect healing. The trial does not specify a washout period, but these medications are part of the exclusion criteria.

Is bone graft surgery for peri-implantitis using InterOss Collagen safe for humans?

The studies reviewed do not provide specific safety data for InterOss Collagen in bone graft surgery for peri-implantitis, but they do suggest that using collagen membranes and bone substitutes in similar procedures is generally considered feasible and safe. However, more research is needed to confirm safety in larger groups.12345

How is the treatment InterOss Collagen unique for peri-implantitis?

InterOss Collagen is unique for treating peri-implantitis because it combines a bone graft material with collagen, which may help in both bone regeneration and soft tissue healing. This dual approach can potentially enhance the stability and success of the treatment compared to using bone grafts or collagen alone.678910

What data supports the effectiveness of the treatment InterOss Collagen, InterOss Collagen Guide for peri-implantitis?

The research suggests that regenerative surgical treatments, which may include bone substitutes like InterOss Collagen, can be effective in treating peri-implantitis, as they help in bone regeneration and improving clinical outcomes over time.1112131415

Are You a Good Fit for This Trial?

This trial is for adults over 18 with peri-implantitis, who are patients at the University of Pittsburgh Periodontics Department. They must have good oral hygiene scores and be systemically healthy. Excluded are those with uncontrolled oral diseases, allergies to dental anesthetics, diabetes, certain medication histories, pregnant or lactating women, heavy smokers, and individuals with conditions affecting healing.

What Are the Treatments Tested in This Trial?

Interventions

  • InterOss Collagen
  • InterOss Collagen Guide
Trial Overview The study compares two surgical treatments for peri-implantitis: one using a bone graft alone (InterOss Collagen), and another combining the bone graft with a resorbable collagen membrane (InterOss Collagen Guide). The goal is to see which method better improves bone defects around dental implants.
How Is the Trial Designed?
2Treatment groups
Experimental Treatment
Active Control
Group I: Bone grafting with collagen membraneExperimental Treatment1 Intervention
This arm will receive surgical intervention involving placement of a bone xenograft subsitute (InterOss Collagen) into the peri-implant bone defect with a collagen membrane (InterCollagen Guide) placed over the bone graft.
Group II: Bone grafting without collagen membraneActive Control1 Intervention
This arm will receive surgical intervention involving placement of a bone xenograft subsitute (InterOss Collagen) into the peri-implant bone defect with no collagen membrane placed over the graft.
