EVALUATION OF THE SOCKET SHIELD TECHNIQUE FOR IMMEDIATE IMPLANTATION

Abstract

INTRODUCTION: Numerous publications have verified that tooth extraction is followed by dimensional changes of the alveolar ridge contour. The resorption of the alveolar ridge is more pronounced on the buccal than on the lingual aspect of the extraction socket. In particular, in the aesthetic zone, the successive soft and hard tissue deficiencies can interfere with optimal implant positioning and hamper the overall aesthetic outcome of implant-supported prostheses. OBJECTIVES: This study was designed to evaluate the socket shield technique clinically and radiographically as a new modality for immediate implantation in comparison to the conventional technique. MATERIALS AND METHODS: twenty patients were included in this study (n=20). They were divided in two groups; group I: Ten maxillary single rooted teeth were extracted followed by immediate implant placement using the socket shield technique. Group II: Ten maxillary single rooted teeth were extracted followed by immediate implant placement using the conventional technique. All implants were evaluated clinically and radiographically to evaluate bone loss on intervals of 1, 4 and 7 months. RESULTS: the mean horizontal and vertical bone loss value in socket shield technique group was 0.09±0.03mm & 0.43±0.23mm contrary to the conventional implantation after 7 months follow up, which was 0.33±0.14mm & 1.56±0.77mm which was statistically significant. CONCLUSIONS: The socket shield technique was beneficial in preserving the buccal bone plate
