Study type | Interventional |
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 970 nm laser combined with scaling and root planning (SRP) is clinically comparable to conventional mucosal flap surgery in terms of pocket probing depth reduction.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Mean change in pocket probing depth (PPD) | 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. | 0-6 months | |
Secondary | Mean change in plaque index (PI) | Plaque index (PI) will be measured at 4 sites per implant and assessed as per cent of the total amount of measured implant surfaces. | 0-6 months | |
Secondary | Mean change in bleeding on probing (BOP) | BOP will be registered on 4 surfaces surrounding the implant after probing the peri-implant pocket with a pocket probe, up to 20 s after the provocation with the probe. | 0-6 months | |
Secondary | Mean change in presence of suppuration | Presence of suppuration will be registered on 4 surfaces surrounding the implant after probing the peri-implant pocket with a pocket probe, up to 20 s after the provocation with the probe. | 0-6 months | |
Secondary | Mean change in marginal bone level on radiographs | Measured on radiographs for a fixed point on the dental implant to the marginal bone level. | 0-6 months | |
Secondary | Mean change in inflammatory response in peri-implant crevicular fluid (PICF) | Analysis of inflammatory meditators in PICF will be performed by commercially available ELISAs or multiplex assays at base line and 6 months. The analytes of interest to be tested are mainly inflammatory cytokines, chemokines, growth factors, proteases, and molecules related to bone remodeling such as for IL-1ß, MMP 8, TIMP-1, CSF-1, elastase activity, and RANK-L/OPG ratio. | 0-6 months | |
Secondary | Mean change in inflammatory response in saliva | Analysis of inflammatory meditators in stimulated saliva will be performed by commercially available ELISAs or multiplex assays at base line and 6 months. The analytes of interest to be tested are mainly inflammatory cytokines, chemokines, growth factors, proteases, and molecules related to bone remodeling such as for IL-1ß, MMP 8, TIMP-1, CSF-1, elastase activity, and RANK-L/OPG ratio. | 0-6 months | |
Secondary | Composition of the subgingival microflora | The bacterial composition in the subgingival microflora will be analyzed by quantitative real-time Polymerase Chain Reaction (qPCR). | 0-6 months | |
Secondary | Mean change in patient reported outcome using the visual analogue scale (VAS) score | Visual analogue scale (VAS) is used to record the patients pain, discomfort and satisfaction with the treatment. The patients mark their response on a 100 mm line, with low values being no feeling of pain, discomfort or satisfaction, and high values meaning maximum pain, discomfort or satisfaction. | Baseline, directly after treatment, 10 days after and 6 months after treatment. |
