The aim The present study aims to conduct a descriptive analysis by reviewing in vivo and in vitro studies concerned with the antibacterial
effect of Er,Cr:YSGG laser (2780 nm) and their effects on implant surfaces at different parameters for peri-implantitis treatment.
Materials and methods The PubMed and Google Scholar had been used to search for articles that focused on the antibacterial
effect of Er,Cr:YSGG laser (2780 nm) in the treatment of peri-implantitis and their effects on implant surfaces. This literature
search was limited to ten years (January 2007–March 2017).
Results The favorable settings of Er,Cr:YSGG laser which can be used significantly to treat peri-implantitis without titanium
surface characteristic alteration or increase of temperature based on reviewed articles are in a non-contact mode (0.5 mm distance)
at 1 and 1.5 W, 10 and 30 Hz, and 60 and 120 s, respectively, under air and water flow for refrigeration.
Conclusion Er,Cr:YSGG laser with specific parameters is an effective tool in the treatment of peri-implantitis without negative
effect on the implant surfaces.

Dental implant surface
A dental implant is a metal anchor that is placed into the jaw
bone to support a dental prosthesis such as a crown, bridge,
and denture or to act as an orthodontic anchor [1, 2]. Dental
implant is an ideal option for people in a good oral health who
have a loss of tooth or teeth due to periodontal disease, an
injury, or other reasons . However, there are many factors
which affect the success of dental implant and its fusion with
the bone (osseointegration). These factors include the follow-
ing: misunderstanding the anatomy and the dental implant
fundamentals, in addition to factors related to the patient such
as uncontrolled diabetes, cancer, radiation to the jaw,
smoking, alcoholism, uncontrolled periodontal disease .
There are risks and complications related to implant thera-
py which are divided into three stages based on their time of
1 Risks and complications during surgery include infection,
excessive bleeding, and necrosis of the tissue flap around
the implant [2, 4].
2 Risks and complications in the first 6 months include in-
fection, excessive bleeding, flap breakdown, and loss of
secondary stability [2, 4].
3 Long-term complications (biological and mechanical
& Biological complications include mucositis, peri-
implantitis, and peri-implant abscess [2, 4].
& Mechanical complications include fracture of implant,
loosening of screw, and loss of retention [2, 4].
Shortly after implants are placed, glycoproteins from saliva
adhere to exposed titanium surfaces with concomitant
