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.


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.


At 3, 6, and 12 months postoperatively, there were no reported complications, with probing depths of 3 to 5 mm, <1 mm recession, no bleeding or implant mobility, and good bone formation. Slight pus discharge was present at 12 months. At 18 months postoperatively, probing depth was 2 mm, recession was <1 mm, there was no bleeding, implant mobility, or discharge, and there was better bone formation. The results were satisfactory to the patient and the clinician.


The Er,Cr:YSGG laser enabled regenerative osseous surgery around an implant with no complications and with high patient and clinician satisfaction and confidence.
