NCT03166475

Brief Summary

A prospective randomized controlled trial of 30 patients from the Faculty of Dentistry of the UFJF was conducted. It was included patients who presented indication of extraction of premolars, canines or incisors. All the thirty patients underwent dental extraction and were randomly divided into three groups according to the study methodology. Plaster casts and Cone-Beam Computed Tomography (CBCT) exams were performed for comparative analysis between sample groups and between study times ( imediate postoperative and four months later).

Outcome Measures

Primary Outcomes (1)

  • Changes of bone remodelation measured by Cone-Beam Computed Tomography exams and by plaster casts analysis, from baseline to 4 months

    Will be measured width and height buccal-lingual of the ridge for each tooth extracted by the researcher.

    Baseline (immediate postoperative) and 4 months after it.

Study Arms (3)

Palatal pedicle flap (Group 1)

EXPERIMENTAL

On patients of this group were performed the palatal pedicle subepithelial connective tissue flap after the extraction, following the technique described by Khoury \& Happe (2000), which consists of total detachment of the palatal flap followed by division of the flap to release the connective tissue, maintain a pedicle and sliding it to cover the fresh socket by primary intention. The sutures were removed seven to ten days of postoperative.

Procedure: Surgical procedures

Graft + palatal pedicle flap (Group 2)

EXPERIMENTAL

On patients of this group were performed the palatal pedicle flap like the group 1, however, the sockets were previously filled with a graft of synthetic bone substitute (Bone Ceramic®, Straumann, Switzerland) and then recovered with the connective flap and sutured by primary intention. The sutures were removed seven to ten days of postoperative.

Procedure: Surgical procedures

Provisional ovoid pontic (Group 3)

EXPERIMENTAL

On patients of this group, after the extraction of the tooth, were made a provisional ovoid pontic with acrylic resin or with the crown of the removed tooth itself, cut and sealed with composite resin. The pontics were placed to seal the entire gingival margin of the socket and penetrating 2 to 3 mm into it, stabilized laterally by the adjacent teeth with orthodontic and composite resin or acrylic resin. No sutures were made.

Procedure: Surgical procedures

Interventions

All the extractions were performed under local anaesthesia, minimally traumatic as possible. After the extraction, each patient was treated according to the group of their allocations.
