Detailed Description
With the widespread use of dental implants, there is an increase in technical and biological complications. These complications are called peri-implant diseases in general terms. When peri-implant diseases are not treated, a process that progresses to the loss of the affected implant may develop, but there is still no accepted consensus on their treatment.When performing treatment procedures, it is recommended not only to remove inflamed tissues but also to decontaminate infected implant surfaces.Recently, with the development of laser technologies, the use of dental lasers in implant surface detoxification has come to the fore. Dental lasers attract increasing attention due to their anti-infective properties, easy handling and haemostatic effects against periodontal pathogens.Diode lasers attract attention with their safety when used directly on the implant surface, soft tissue penetration, antibacterial and biostimulating properties. They detoxify implant surfaces by killing pathogenic bacteria through photothermal effects and neutralizing bacterial endotoxins. Erbium lasers also show promising results in implant treatment due to their advantageous properties such as soft and hard tissue ablation and decontamination. Er, Cr: YSGG lasers have the ability to debride microstructured surfaces of dental implants without causing mechanical damage, thanks to their ability to work with water.Today, many researchers investigate the effectiveness of dental lasers in the treatment of peri-implant diseases, but it has not yet been proven whether they have an additional contribution. It is observed that studies mostly focus on clinical parameters. However, it is stated that periodontal probing and radiographs, which are used as common diagnostic methods, may give erroneous results. These methods refer only to pre-existing destruction rather than current disease activity. A model predicting the course of peri-implant disease has not yet been defined, but biomarkers may offer considerable potential for disease activity.Biomarkers are widely used in medicine to objectively determine disease state or responses to a therapeutic intervention. Gingival fluid (GCF) biomarkers have moderate diagnostic validity in periodontitis. It is stated that biomarkers in peri-implant groove fluid (PICF) also give promising results in terms of diagnosis and prognostic values. MMP-8 and MMP-9, the two main collagen degrading enzymes in GCF, are secreted from neutrophils during disease activation and are responsible for extracellular matrix degradation. TIMP-1, a major inhibitor of MMPs, has been reported to be released at high levels in inflamed gums.
In the literature review, it has been observed that there are quite a limited number of human clinical studies investigating the effect of dental lasers of different wavelengths on treatment results in the treatment of peri-implant disease at the clinical and molecular level. The aim of this study is to investigate the effects of 940 nm diode laser and 2780 nm Er, Cr: YSGG laser-assisted non-surgical mechanical treatment on clinical parameters and MMP-9 and TIMP-1 levels in PICF in individuals with peri-implant disease.

PLACEBO_COMPARATOR: Traditional non-surgical mechanical therapy
Mechanical instrumentation in all groups continued with titanium Gracey curettes (8mm in diameter, Langer ½, item code: 7103, Kohler Medizintechnik, GmbH & Co, Ltd, Stockach, Germany) until the clinician gently felt that the surface was sufficiently debrided.There is no laser application.
The laser tip is placed in the peri-implant sulcus but not activated.

ACTIVE_COMPARATOR: Diode laser-assisted non-surgical mechanical therapy
1 week after mechanical debridment, 940 nm diode laser (Ezlase®, Biolase Technology, Inc., San Clemente, CA) has been applied with the aid of a 300 µm diameter optical fiber tip (E3-9 mm) placed approximately 1 mm above the most apical part of the peri implant pocket, parallel to the implant surface.
Pocket irrigation was performed with 3% hydrogen peroxide solution for 10 seconds before and after diode laser application.The fiber was moved in apico-coronal and mesial-distal directions for a total of 30 seconds during laser light emission.The laser tip was checked every 7-8 seconds and wiped with sterile saline in order to prevent a possible coagulation or temperature increase.The laser was used in continuous pulse mode, at a power of 0.8 Watt (W), an energy density of 3J / cm2 and a spot diameter of 1 mm.
Pulse width and pulse interval were applied as 20 milliseconds.

One week after mechanical treatment, a 940 nm diode laser (Ezlase®, Biolase Technology, Inc., San Clemente, CA) with a 300 µm diameter optical fiber tip applied approximately 1 mm above the most apical part of the peri-implant pocket, parallel to the implant surface (E3-9 mm).

ACTIVE_COMPARATOR: Er, Cr: YSGG laser-assisted non-surgical mechanical therapy
1 week after mechanical debridment, 2780 nm Er, Cr: YSGG laser (Waterlase®, Biolase Technology, Inc., San Clemente, CA), with 500 µm diameter fiberoptic periodontal tip (RFPT5-14 mm) was applied in short pulse '' H '' mode, water cooled with a non-contact sweeping motion for 30 seconds parallel to the implant surface.The settings used are: 1.5 W power, 30 Hz frequency, 50% water, 40% air, 140 s pulse duration and 1 cm spot size.
