Online Article: Er:YAG Laser for Surgical Crown Lengthening: A 6-Month Clinical Study
Chen, Chang-Kai / Wu, Yung-Tsan / Chang, Nai-Jen / Lan, Wan-Hong / Ke, Jyuhn-Hurng / Fu, Earl / Yuh, Da-Yo
This study evaluated use of a solid-state laser to avoid the flap technique and suturing. An Er:YAG laser was used in 26 consecutive patients referred for osseous crown lengthening in 32 posterior teeth. The distance from the planned restoration margin to the alveolar crest (B) satisfied a 3-mm dentogingival complex. No tissue necrosis and no significant change in the distance from the gingival margin to B or probing depth were detected at 3 and 6 months. Minimally invasive Er:YAG laser surgery decreases the time needed to establish the gingival margin necessary for definitive restoration.
