Patients were randomly divided into two groups. In 30 patients one side of the bony cover around the tooth was removed by the conventional bur technique, on the other side 15 patients were treated with the Er:YAG laser (VersaWave dental laser; HOYA ConBio) 200 mJ, 30 Hz, 4.5-6 W, noncontact mode, SP and R-14 handpiece tip, under air and saline solution, and 15 patients with the piezosurgery technique (VarioSurg Piezo; NSK) with frequency 20-100 kHz, 10-80% power range in Surgery (S), continuous mode, with SG17 and SG5 handpiece tip blade.
