Dental implantsImmediate Reconstruction of Failed Implants in the Esthetic Zone Using a Flapless Technique and Autogenous Composite Tuberosity Graft
Section snippets
Technical Note
A cone beam computed tomography (CBCT) scan was made to assess the peri-implant bone volume in the area with the failing implant (Fig 1). In addition, a provisional removable partial denture with an ovate pontic shape was fabricated. Clasp retainers were added to prevent deleterious apicocoronal movement of the provisional restoration.
At 1 day preoperatively, the patients started prophylactic antibiotic therapy (amoxicillin 500 mg, 3 times daily for 7 days, or clindamycin 300 mg, 4 times daily,
Results
The technique was evaluated in 16 consecutive patients (6 men and 10 women; mean age 31.7 ± 4 years, range 19 to 53) with a failing implant in the esthetic zone. In all cases, the CBCT scan revealed extensive bone resorption on the labial side of the implant that had exceeded one half of the implant length. Bone sounding revealed that all patients had an extensive osseous defect of the buccal bone wall side, ranging from 6 to 10 mm from the top of the mucosa. No complications were observed
Discussion
Immediate reconstruction of the soft tissues and bone in the area of a removed implant was associated with favorable implant retreatment outcomes, with no implant loss, good peri-implant health, and satisfactory esthetics.
In the published data, the survival rates after reimplantation at sites in which implants had previously failed were lower than those involving placement of implants in bone in which the implants had not failed.2, 6, 7 The standard approach to remove failing implants often
