Plain English summary of protocol

Background and study aims
Peri-implantitis is an inflammation of the gums and bone around a dental implant that can lead to loss of bone. Peri-implantitis a common occurrence in clinical practice is and the frequency of this problem is increasing due to wide choices in dental implant options. Currently, there is no unified protocol that provides clear, specific steps and an effective method to treat peri-implantitis.

Who can participate?
Adult patients with peri-implantitis.

What does the study involve?
Participants will be allocated to receive one of three different mechanical methods to clean the implant surface (manual curettage, titanium brush, and diode laser) during the procedure, with an equal chance of receiving each. At 6 months after surgery, the participants will undergo clinical and radiological assessments to evaluate the effectiveness of each method.

What are the possible benefits and risks of participating?
The main benefit of this study is the possibility to receive a recommendation for, and treatment with, the most effective method to use in treating peri-implantitis. There is a risk of not achieving good results in some cases, however, due to the follow-up period of 6 months post-operation, the study team can manage these cases.

Where is the study run from?
Damascus University (Syria)

When is the study starting and how long is it expected to run for?
From May 2022 to April 2024

Who is funding the study?
Damascus University (Syria)

Scientific titleA comparative study to evaluate the efficacy of three different methods of peri-implantitis surgical regenerative interventions
Study objectivesDo the three methods used in this research to treat implant surfaces have clinical and radiographical differences?
Ethics approval(s)Approved 15/03/2022, Scientific Research Committee Faculty of Dentistry at Damascus University (Mazzeh Highway, Damascus, Syria; +963113341864; manager@hcsr.gov.sy)
Health condition(s) or problem(s) studiedPeri-implantitis
InterventionFirst, cases will be diagnosed clinically and radiographically to ensure the matching of inclusion criteria.
After local anesthesia, a full thickness flap will be made in the implant site, and the affected areas around the implant will be determined. Participants will be randomised to receive one of the three selected mechanical methods (manual curettage, titanium brush, and diode laser). For all participants, this will then be followed by chemical agents EDTA 19% and local antibiotic, and covering implants surface with the bone graft then confirm a very tight closure.
The randomization of the sample will be done by giving a number for each acceptable case within the research and placing a letter numbering for the three research groups, a case number will be drawn with a corresponding of letters to determine the method of work for each case.
Intervention typeProcedure/Surgery
Primary outcome measure1. Microscopic topography of the implant surface formed after applying each method of mechanical treatments measured using scanning electronic microscope SEM at baseline and 6 months after the grafting process
2. Dimensions of the grafted alveolar ridge in the area of the implant at the transverse plane measured (clinically) using cone-beam computed tomography systems (CBCT) the day following the surgery and 6 months after the grafting process
3. Dimensions of the grafted alveolar ridge in the implantation area at the transverse and vertical levels measured using cone-beam computed tomography systems (CBCT) at baseline and 6 months after the grafting process
4. Gingival health measured using assessment of gingival indices, bleeding on probing (BOP), and peri-implant pocket depth (PPD) at baseline and 6 months after the grafting process
Secondary outcome measures1. Effect on the keratinized gingiva measured using keratinized gingival width will be measured by a periodontal probe from a reference point at the buccal side of the implant (mid buccal surface of the gingival former) to the MGJ (muco-gingival junction) before the surgery and 6 months after the grafting process
2. Pain after surgery measured using a visual analogue score (VAS) at baseline, 24 h, 48 h, and one week after surgery at baseline and 6 months after the grafting process
3. Patient satisfaction with the surgical procedure measured using patient satisfaction questionnaire (PSQ-18) at 6 months after the grafting process

Completion date15/04/2024
