Study Overview

Brief Summary

A clinical trial comparing laser treatment and conventional mucosal flap surgery for treatment of peri-implantitis. The main aim of the study is to evaluate if treatment of peri-implantitis with a novel blue laser (445 nm) combined with scaling and root planning (SRP) is clinically comparable to conventional mucosal flap surgery in terms of pocket probing depth reduction.

Detailed Description

The present project aims to evaluate a novel method in treating peri-implantitis, with focus on decreasing the patient's suffering as well as disease progression. Peri-implantitis has a direct influence on both physical and psychological well-being and have been related to difficulty in chewing due to loss of implants, bad esthetic appearance as well as high costs. Therefore, it is of importance for the individual as well as for the society to thoroughly investigate any new treatment approaches.

The study is a prospective randomized clinical trial comparing laser treatment (test group) and conventional mucosal flap surgery (active control group). Assessment of clinical variables at baseline and after 6 months. Patient reported outcomes at baseline, directly after treatment and after 10 days.

Primary Objective:

To evaluate if treatment of peri-implantitis with a novel blue laser (445 nm) combined with scaling and root planning (SRP) is clinically comparable to conventional mucosal flap surgery in terms of pocket probing depth reduction.

Arms & Interventions

Scaling and root planning + Laser treatment

Experimental

Intervention: Laser treatment (Device)

Mucosal flap surgery

Active Comparator

Intervention: Mucosal flap surgery (Procedure)

Outcomes

Primary Outcomes

Mean change from baseline in Pocket probing depth (PPD) at 6 months after treatment.

Time Frame: At baseline and 6 months post treatment

Pocket probing depth (PPD) will be measured by a 1 mm graded pocket probe from the bottom of the peri-implant pocket to the marginal mucosa and will be registered on 4 surfaces surrounding the implant.

Secondary Outcomes

  • Bacterial composition of the subgingival microflora(At baseline and 6 months post treatment)
  • Mean change from baseline in Plaque index (PI) at 6 months after treatment.(At baseline and 6 months post treatment)
  • Mean change from baseline in the inflammatory response in the inflammatory exudates at 6 months after treatment.(At baseline and 6 months post treatment)
  • Mean change from baseline in Bleeding on probing (BOP) at 6 months after treatment.(At baseline and 6 months post treatment)
  • Mean change from baseline in Recession of the marginal mucosa at 6 months after treatment.(At baseline and 6 months post treatment)
  • Mean change from baseline in Patient reported outcome using the VAS score directly post treatment.(At baseline and immediately post treatment.)
  • Mean change from baseline in Patient reported outcome using the VAS score at 10 days post treatment.(At baseline and 10 days post treatment.)
  • Mean change from baseline in Presence of suppuration at 6 months after treatment.(At baseline and 6 months post treatment)
  • Mean change from baseline in Marginal bone level on radiographs at 6 months after treatment.(At baseline and 6 months post treatment)
