Reabilitação dentária em região anterior com implante imediato e reconstrução alveolar por meio de enxertos conjuntivo autógeno e ósseo xenógeno

Abstract

The immediate implant, in addition to provide reduction of clinical treatment time, aims to promote preservation of marginal bone ridges and maintain the emergency profile of the dental crown. The present study shows a clinical procedure involving minimally traumatic extration, followed by the immediate installation of a morse taper implant (Alvim 3,5 x 13 mm, Neodent®) in addition to the use of subepithelial connective tissue graft (SCTG). In order to remedy a loss of remnant alveolar bone tissue, bovine biomaterial (Geistlich Bio-Oss®) was used in alveolar reconstruction also with the intention of covering implant’s spires and promoving stability for the recently grafted soft tissue. After the surgical installation of the implant was completed, an initial 30N locking was obtained, what made impossible the immediate installation of a provisional over the implant. Then fixed temporary restoration was carried out, using a pontic with cervical ovoid format to maintain height, emergency profile, and interdental papilla contour. After 4 months of postoperative, was carried out surgery of implant reopening, with a new graft of connective tissue using the technique called pediculated, aiming the gain of vestibular tissue volume. Universal abutment type prosthetic component morse taper was used (measuring 3,3 x 4 x 6,5 mm Neodent®) and was carried out the confection and cementation of implant supported provisional. After a few weeks, the definitive crown was installed. With those procedures, for proper planning, and highly regarded techniques, a highly satisfactory functional and aesthetic result could be obtained.
