The Effect of Peri-implant Surgery & Chair-side Supportive Post Surgical

Status Completed

Clinical Trial Summary

Peri-implantitis is defined as inflammation in the mucosa surrounding an oral implant with loss of supporting bone. The goals of peri-implantitis treatment are to resolve inflammation and to arrest the progression of disease. It is important to systematically gather information on the effect of surgical peri-implant treatment and to assess different protocols regarding chair-side maintenance of peri-implant tissue after surgery The aims of this clinical investigation are to evaluate the clinical, microbiological and radiographic outcomes of surgical treatment of peri-implantitis and to evaluate the efficacy of 2 supportive treatment protocols based on the use of titanium cyrettes or by the use of a flexible, biodegradable chitosan brush. Furthermore, to evaluate the impact of this therapy on selected biochemical markers associated with chronic inflammation and bone tissue destruction.

Clinical Trial Description

Little is known about the effect of chair-side maintenance of dental implants after peri-implantitits surgery. Traditionally, the maintenance has been performed by titanium curettes to remove microbiological deposits from the submucosal area. The Labrida biodegradable brush is a novel debridement device intended for use on dental implants. The concept of using a biodegradable material is related to the suggested problems with leaving remnants on the treated implant surface which would be negative from a bone regenerative aspect. The use of a flexible brush relates to the access problems when treating dental implants both related to the threads as well as due to the prosthetic supra construction hindering access for debridement with regular instruments developed for teeth. The material used in the brush will be Chitosan which is a natural polysaccharide, chitosan (poly-N-acetyl glucosaminoglycan), which is a nontoxic and bioabsorbable (REK-approval 2012/791 polymer). H0: It is possible to maintain peri-implant health after surgical peri-implantitis treatment. There is no short- or long term clinical or radiographical differences between patients surgically treated for peri-implantitis maintained by the use of titanium cyrettes or with the Labrida brush in chair-side supportive care ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
