Brief summary

A laser treatment for periimplantitis using two different wavelengths (Er:YAG and Nd:YAG) will be compared to standard treatment in a randomized clinical trial.

Detailed description

The general aim of this study is to evaluate the clinical outcome of the treatment of peri-implantitis using a combination of a Er:YAG and Nd:YAG laser protocol or using a conventional mechanical treatment in patients with a diagnosis of peri-implantitis.

Interventions

DEVICELightwalker Laser (Fotona)

For the laser group we will use a Lightwalker Laser (Fotona) with a Er:YAG 2940 nm and Nd:YAG 1064 nm wavelengths units. The laser protocol will follow the instructions of the manufacturer (TwinLight protocol) and consists of degranulation of necrotic soft tissue and bone, implant surface disinfection and creating spot bleeding in bone with Er:YAG and deep disinfection and biomodulation with Nd:YAG.

OTHERstandard

Granulation tissue elimination, mechanical instrumentation of the implant surface and curettage of intraosseous or supracrestally bone defects will be accomplished using plastic curets, under irrigation with sterile saline solution. Cotton pellets soaked in sterile saline solution will be use to clean debris and remains of removed tissue.

Design outcomes

Primary

MeasureTime frameDescription
Proportion of participants with treatment success6 monthsTreatment success defined as implant survival with the absence of peri-implant probing depths (PD) greater than 5 mm with concomitant bleeding/suppuration and absence of progression of peri-implant bone loss.

Secondary

MeasureTime frameDescription
Bleeding on probing1 month(BOP) evaluated as present if bleeding was evident within 30 s after probing, or absent, if no bleeding was noticed within 30 s after probing.
Probing depth1 monthmeasured from the mucosal margin to the bottom of the pocket.
Plaque index1 month(PI)
Clinical attachment level gain1 monthDifference in clinical attachment level at baseline and follow up.
Quality of life questionnaire0 monthsOral Health Impact Profile-14 on the scale from 0 to 56 with higher scores indicating a poorer oral health-related quality of life.
Mucosal recession1 monthmeasured from the mucosal margin to the bottom of the pocket.
