Crown Lengthening with Minimally Invasive Flap Design

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.

The permanent crown is delivered four weeks after the crown lengthening procedure. The margin is three millimeters from the osseous crest and adequate ferule established.
