Er,Cr:YSGG Laser‐Assisted Surgical Treatment of Peri‐Implantitis With 1‐Year Reentry and 18‐Month Follow‐Up

Background: Peri‐implantitis may occur because of biologic or mechanical factors. It can be treated by a variety of methods. In the present case report, treatment was attempted by regenerative osseous surgery associated with an erbium, chromium‐doped:yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser. Methods: A 28‐year‐old, non‐smoking male complained of gum recession around an implant in the area of upper left central incisor. After clinical examination and radiographs, it was found that there was 2 mm recession, a probing depth of 7 mm, mobility grade one, and bone mesially and distally. Regenerative osseous surgery was performed using an Er,Cr:YSGG laser (2,780 nm) at different settings to open the flap, remove the granulation tissues, perforate the bone, and clean the implant surface. A bone graft and a bioabsorbable membrane were used for bone regeneration. The patient was reevaluated at 3, 6, 12 (with reentry), and 18 months postoperatively. Results: At 3, 6, and 12 months postoperatively, there were no reported complications, with probing depths of 3 to 5 mm,
