“…The Er:YAG laser settings used in treating peri-implantitis are 100 mJ/pulse, 1 W, 10 Hz, and 12.74 J/cm 2 for 60 seconds. 64 Care should be used when using an Er:YAG laser 2940 nm wavelength to avoid adverse thermal effects on the implant surface. In a clinical study, Clem and Gunsolley 65 evaluated the effective treatment regime for peri-implantitis lesions with deep (≥ 6 mm) defects using an Er:YAG laser for implant surface decontamination, removing defect granulomatous tissues, and grafting therapy for bony defect resolution.…”

Despite the success rates of dental implants, peri-implantitis presents as the most common complication in implant dentistry. This review discusses various factors associated with peri-implantitis and various available treatments, highlighting their advantages and disadvantages. Relevant articles on peri-implantitis published in English were reviewed from August 2010 to April 2020 in MEDLINE/PubMed, Scopus, and ScienceDirect. The identified risk indicators of peri-implant diseases are plaque, smoking, history of periodontitis, surface roughness, residual cement, emergence angle >30 degrees, radiation therapy, keratinized tissue width, and function time of the implant, sex, and diabetes. Peri-implantitis treatments can be divided into nonsurgical (mechanical, antiseptic, and antibiotics), surface decontamination (chemical and laser), and surgical (air powder abrasive, resective, and regenerative). However, mechanical debridement alone may fail to eliminate the causative bacteria, and this treatment should be combined with other treatments (antiseptics and surgical treatment). Surface decontamination using chemical agents may be used as an adjuvant treatment; however, the definitive clinical benefit is yet not proven. Laser treatment may result in a short-term decrease in periodontal pocket depth, while air powder abrasive is effective in cleaning a previously contaminated implant surface. Surgical elimination of a pocket, bone recontouring and plaque control are also effective for treating peri-implantitis. The current evidence indicates that regenerative approaches to treat peri-implant defects are unpredictable.

“…Heterogeneity in protocol, variation in included parameters, and lack of information concerning calibration of the laser equipment and measuring instruments hamper comparisons between studies (Kamel et al, 2014;Smeo et al, 2018). Most laser systems report a discrepancy between device power/energy setting and actual output power/energy.…”

Objective: To estimate the implant surface temperature at titanium dental implants during calibrated irradiation using double wavelength laser.Material and methods: A double wavelength laser, 2780 nm Er,Cr:YSGG and 940 nm diode, was calibrated and used to irradiate pristine titanium dental implants, OsseoSpeed, TiUnite and Roxolid SLActive, representing different surface modifications. Initial calibration (21 implants; 7 implants/group) intended to identify optimal wavelength/specific output power/energy that not critically increased the temperature or altered the micro-texture of the implant surface. Subsequent experimental study (30 implants; 10 implants/group) evaluated implant surface temperature changes over 190 s. Irradiation using a computerized robotic setup.Results: Based on the initial calibration, the following output powers/energies were employed: Er,Cr:YSGG laser 18.4 mJ/pulse (7.3 J/cm 2 )-36.2 mJ/pulse (14.4 J/cm 2 ) depending on implant surface; diode laser 3.3 W (1321.0 W/cm 2 ). During double wavelength irradiation, implant surface temperatures dropped over the first 20 s from baseline 37 C to mean temperatures ranging between 25.7 and 26.3 C. Differences in mean temperatures between OsseoSpeed and TiUnite implants were statistically significant (p < 0.001). After the initial 20 s, mean temperatures continued to decrease for all implant surfaces. The decrease was significantly greater for TiUnite and Roxolid SLActive compared with OsseoSpeed implants (p < 0.001). Conclusion:Calibrated double wavelength laser irradiation did not critically influence the implant surface temperature. During laser irradiation the temperature decreased rapidly to steady-state levels, close to the water/air-spray temperature.

“…The parameter values given in Table 1 are based on the recommendation of the previous study for peri-implantitis treatment that avoids any surface defect and increases the temperature. 18,24,25 Er,Cr:YSGG laser in non-contact mode with 0.5 mm distance and parameters in Table 2 were used for surface treatment of samples. The laser tip was MZ6 quartz with the fiber diameter of 600 mm and 50% water and 50% air.…”

“…Studies have shown that, regardless of implant surface alteration, using erbium, chromium-doped yttrium scandium gallium garnet (Er,Cr:YSGG) laser can lead to antibacterial properties of the implant surface. [18][19][20] However, surface defects on implant surfaces using Er,Cr:YSGG laser were reported. 21 A. actinomycetemcomitans and E. corrodens were selected due to their role in inflammation around the implant and also periodontitis.…”

Dental implants play an important role in oral health. Titanium dental implants must endure the complex microflora environment of the oral cavity. Moreover, bacterial infections have been considered as one of the most important factors of implant failure. The issue of dental improvement through modification of chemical composition and surface treatment has received considerable critical attention. γ-TiAl as a novo biocompatible material revealed a slower corrosion rate in biological media rather Ti-6Al-4V. The objective of this study is to investigate the effect of Er,Cr:YSGG laser on γ-TiAl in comparison with sandblasted and acid-etched samples as the control groups and machined samples. Wettability, surface roughness, surface topography, scanning electron microscopy–energy dispersive X-ray spectrometer analysis of surface and subsurface of samples were investigated and bacteria counts of two periodontal bacterial strains ( Aggregatibacter actinomycetemcomitans and Eikenella corrodens) were evaluated on the Er,Cr:YSGG laser surface-treated sandblasted and acid-etched and machined samples. The results of this investigation show that Er,Cr:YSGG laser surface treatment affects surface roughness, surface topography, wettability, chemical composition of the surface and bacteria count. Scanning electron microscopy–energy dispersive X-ray spectrometer analysis of the sample revealed the increment of titanium and oxygen content and reduction of aluminum content in the surface and subsurface layer. A. actinomycetemcomitans and E. corrodens count were found from the lowest level to highest in the sandblasted and acid-etched samples, laser samples and machined samples, respectively. Using controlled parameters of Er,Cr:YSGG laser ensured no significant adverse alteration. The findings to emerge from this study revealed the significant correlation between microbial count and wettability. Furthermore, the contact angle strongly correlated with surface roughness.
