THE DE-EPITHELlALlZED CONNECTIVE TISSUE PEDICLE GRAFT (Roll Technique)

Basically, it is a form of contiguous grafting (pedicle graft} which utilizes as the donor site only the connective tissue of the palate adjacent to the ridge. The epithelium over the pedicle is first removed. This is readily done, using a non-epinephrine bearing anesthetic, by sharp dissection or by use of a rotary diamond instrument. Free bleeding, permitted by the non-epinephrine anesthetic, is evidence of complete epithelial removal. The tissue is then infiltrated with an anesthetic containing a hemostatic agent, and a connective tissue pedicle flap is outlined through to the osseous, and then elevated from the palate within the de-epithelialized zone. In this procedure, it is important that the proximal marginal tissue of the adjacent abutment teeth is not involved. This will ensure stability of the crown margin to tissue relationship.

Surgical Preparation of the Pontic Recipient Site

If the level of the healing ridge is too far corbnal for an esthetic pontic, the anatomical topography of the site must be determined by needle probing under local anesthesia. If there is a thickness of 3 or 4 mm of soft tissue above the alveolus in the center of the ridge, it is necessary only to perform soft tissue gingivoplasty, developing an anatomical configuration compatible with the two adjacent teeth. This is easily accomplished with a rotary diamond instrument. A 1 mm concavity for the base of the pontic, further apical to the maximal curvature of the adjacent marginal gingiva, is developed. To fit into this area, the temporary pontic is relined with self-curing acrylic, trimmed, and polished, allowing the tissue to heal around this ovate form. Continue reading →

Types of pontic Part 1

In those clinical situations in which missing teeth are replaced with fixed prosthodontics, the clinician is faced with the task of fabricating the pontics to fulfill the requirements of esthetics, form and function, and oral physiotherapy. Continue reading →
