Objective: This study aims to collect data on implant survival, bone volume maintenance, and complications associated with the socket shield technique.
Background Data: The socket shield technique was introduced in 2010. Since then, several systematic reviews have been published, showing good clinical outcomes. The behaviour of the buccal bone plate is so far not completely understood.
Methods: The study involved the placement of 23 implants using the socket shield technique in 20 patients. AstraTech EV implants were used, and no bone substitutes or connective tissue grafts were applied. Patients were monitored for 18 months, recording implant survival, volumetric bone analysis on CBCT scans, interproximal bone levels, bone sounding, pink esthetic scores, and complications. Prosthetic procedures were also described, including temporary and final restorations.
Results: A 95.7% cumulative 18-month implant survival rate was obtained using the socket shield technique, with a significant but limited reduction in buccal bone thickness (BBT) after implant placement. One implant did not integrate and two shields were partially exposed. The mean pink esthetic score, 1 year after loading was 12.93 ± 1.22.
Conclusion: The study suggests that the socket shield technique can result in limited reduction of the buccal bone volume, with a high implant survival rate. Re-entry studies are recommended to investigate the causes of bone resorption.

Objective: Transcutaneous osseointegration prosthetic systems (TOPS) offer a stable skeletal attachment for artificial limbs post-extremity amputation, serving as an alternative to socket attachment. Press-fit osseointegration implants (OI) utilized in TOPS consistently enhance quality of life and mobility for amputees, particularly those experiencing socket-related issues. Despite notable benefits, late complications such as infection and implant loosening pose challenges unique to TOPS due to their percutaneous nature.

The purpose of this case report is to examine the management of vestibular bone fenestration during alveolar socket preservation using the Periosteal Inhibition (PI) approach. Here, for the first time, the PI technique, which has been shown to be successful in maintaining intact cortical bone, is examined in the context of a bone defect. : After an atraumatic extraction of a damaged tooth, a vestibular bone fenestration was discovered in the 62-year-old male patient.

Introduction: Following tooth extraction, there is comparatively more bone loss at the buccal aspect at 3 months of healing, which may result in 56% bone loss due to resorption of the bucco-facial ridge contour. In the socket shield technique, a tooth is planned for extraction in such a way that the tooth is sectioned in two halves, a palatal section is removed and the facial part is retained.

Objective: In the young and growing patient, tooth ankylosis impedes alveolar growth and presents a serious dilemma regarding the best treatment approach. Two common treatment approaches, extraction of the ankylosed tooth or a "wait and see" will result in a compromised alveolar ridge that can affect future prosthetic rehabilitation. The purpose of this article is to discuss five treatment strategies that can be utilized in the management of tooth ankylosis in the growing patient: (1) extraction, (2) decoronation or root submergence, (3) socket shield (partial extraction), (4) segmental osteotomy and (5) replacement with tooth autotransplantation.
