The increase in cosmetic dental procedures worldwide for the correction of all dental imperfections, including the smile correction treatment is estimated in approximately 300 million people. Dental crown extension or lengthening is an osseous remodeling used in restorative dentistry to recreate the biologic width and/or to correct the proportions of teeth and gums. It typically involves a scalloped incision to recreate the proposed gingival height, a gingival flap and approximately 2 millimeters of bone remodeling. Bone removal can be carried out with a sharp manual instrument, with a conventional rotating drill or an electric piezosurgery unit. Although effective, these procedures have not been embraced widely by the dental community, since they are invasive and carry postoperative discomfort and high risk of complications.

This invention consists of an ultrasonic tip designed for clinical crown lengthen-ing, which includes a proximal end, which is adapted for mechanical coupling to piezoelectric device, designed to determine the precise bone removal depth without needing extra measurements nor detach (create a flap of) gingival tissue, making it minimally invasive. Furthermore, the surgical device avoids sutures and the postoperative convalescence period, enabling the patient to continue normally after surgery. It also prevents tooth damage and acts selectively on the bone tissue removal.
