Summary

The objective of this study is to assess the effectiveness of a Polyether ether ketone (PEEK) stent for management of gummy smile.

Conditions

  • Gummy Smile

Interventions

OTHER

Milled PEEK Stent

A CBCT will be performed to assess the anatomy of the subnasal area and plan the position, size, shape and thickness of the PEEK Stent. These data will be transferred to a 3D planning software to generate a digital model. Eventually, the PEEK stents will be milled in a milling machine and sterilized in ethylene oxide before the surgery. Local anesthesia will be administered into the vestibular mucosa along the extension of the anterior maxilla. VISTA technique begins with a vestibular access incision in the midline frenum and 2 bilateral incisions at premolar area. A periosteal elevator will be introduced through the incision and inserted between the bone and periosteum to elevate the tissue, creating a subperiosteal tunnel, extending distally based on the dynamic of the smile. The PEEK stent will be in one piece. They will be placed onto the bone and stabilized with 2 bone graft screw for each side. The midline incision and the lateral incisions will be sutured primarily.
