Abstract Background: The alveolar ridge resorbs and collapses following tooth removal which continues to be a major concern for practitioners. Many researchers concluded that buccal aspect of the ridge is more prone to resorption, as it is primarily supplied by the periodontal tissues and ligaments of the tooth. Therefore, extraction of the hopeless tooth, may be a reason for buccal cortical plate resorbing at a faster rate than the palatal plate leading to its total degradation. This may lead to dimensional changes in the human ridge and the aesthetic area is highly affected by this process Materials and methods: 28 patients with thin buccal bone not more than 1mm in the anterior region were randomly assigned to 2 groups receiving immediate implantation with socket shield technique or immediate implantation without socket-shield and followed up to 6 months. Buccal bone resorption, thickness, implant stability, pain scale and pink esthetic score were measured at baseline, 6 and 12 months. vi Results: Radiographic assessment showed that socket shield technique with simultaneous implant placement group resulted in gain of bucco-facial bone width compared to that of the conventional immediate placement group height when baseline and postoperative readings were compared after months and 12 months. SS showed promising results in maintaining thin buccal bone, implant stability using Osstell measurements compared to conventional immediate implant placement. Conclusion: Volumetric analysis showed a low degree of contour changes from extraction and implant placement to the follow-ups. Within the limitations of this Randomized controlled study, the socket shield technique offers reduced invasiveness at the time of surgery and high esthetic outcomes with effective preservation of facial tissue contours compared to the conventional immediate implantation. This technique should not be used in routine clinical practice until a higher-level evidence clinical trials is available. |
