Management of two implants in the esthetic zone
A medically and periodontally stable 24-year-old woman presented with two failing root canals on teeth #8 and #9. Her dental records indicated both teeth were endodontically treated twice before. The first root canals were performed when she was 18 years old due to a trauma incident and again six years later.
Two weeks prior to presenting at our office, the patient stated she had another accident causing trauma to her two maxillary centrals. A new series of radiographs revealed apical infections on both teeth (Fig. 1). Both teeth were deemed restoratively hopeless (Fig. 2).
The patient was given the option to have a removable partial denture, fixed partial denture or implants. The following treatment was performed:
- Extraction of teeth #8 and #9 and maxillary periodontal esthetic osseous surgery.
- Temporization with a resin-bonded fixed partial denture during healing period.
- Placement of implants for #8 and #9.
- Six-month healing period.
- Placement of final implant crowns.
- Extraction and socket preservation.
The teeth were extracted followed by a thorough degranulation and debridement of the extraction sites. No dehiscence or fenestration was detected, and no graft material was placed in the extraction sites. The space was then temporized with a resin-bonded fixed partial denture (Fig. 3).
Esthetic periodontal osseous surgery
The primary goal for this procedure was to eliminate the “gummy smile.” Osteoplasty was followed by approximately 1 to 1.5 mm of ostectomy. The flap was repositioned apically (Figs. 4 & 5).
After osteotomy preparation, two internal-hex implants with S.L.A. (sand-blasted with large grit and acid etching) surfaces were placed (Fig. 6).
A 3.8 mm x 12 mm implant was placed into site #8 and a 3.4 mm x 12 mm implant was placed into site #9 (Implantium S.L.A. implant by Dentium USA, Cypress, Calif.). Primary stability was achieved, and healing abutments were placed. The site was re-temporized using the same resin-bonded fixed partial denture that was used during the first healing phase.
Final restoration of both #8 and #9 implants was performed at six months. The marginal height and contours of both implants matched, and a periapical radiograph revealed sufficient bone height around the fixtures (Fig. 7).
The patient was happy with the functional and esthetic results (Fig. 8).
