IMMEDIATE TOOTH REPLACEMENT IN THE ESTHETIC ZONE WITH THE SOCKET SHIELD TECHNIQUE AND A NOVEL BODY-SHIFT IMPLANT: A PILOT STUDY WITH UP TO 3 YEARS OF FOLLOW-UP

Successful rehabilitation of the anterior maxilla remains a challenge, primarily due to postextraction ridge collapse, which can lead to gingival recession and a nonesthetic appearance. The socket shield technique presents a viable alternative for immediate dental implant placement in the esthetic zone. This pilot study aimed to evaluate the survival, complication rates, and marginal bone loss around body-shift implants placed in fresh extraction sockets with the socket shield technique to replace maxillary incisors. After socket shield preparation, 14 hopeless incisors were extracted and immediately replaced by a body-shift implant (Inverta, Southern Implants) at baseline. Patients were followed up for 12 to 39 months (mean: 18.1 +/- 8.2 months). The average age was 52.3 +/- 16.9 years, and the survival rate was 100%. One socket shield presented minimal internal exposure that was successfully treated with a connective tissue graft. The mean PES score was 12.9 +/- 1.2. Mean interproximal marginal bone loss was 0.4 +/- 0.5 mm. Body-shift implants can be a promising alternative for immediate tooth replacement combined with the socket shield technique. The superior esthetic outcomes remained stable, suggesting that the extra space created by the narrow cervical portion of the implant is beneficial for preserving the alveolar bone and limiting internal shield exposure.
