Mesiolingual cusp fracture requires osseous crown lengthening. The fracture was subgingival to the level of the bone. A flap is required due to significant amount of bone needed to be removed and the width of the bone in this region.

A conservative flap is laid using the Er:YAG laser in place of a scalpel. The bone is removed to the proper height and contoured. A band is placed and high contrast composite buildup bonded in place. A single nylon suture secures the minimally invasive flap. The final crown preparation can be done in two to four weeks.
