Socket shield

BACKGROUND: The socket-shield (SS) technique results in long-term functional osseo- and dento-integration, preserving the dimensional stability of hard and soft tissues over time. This study aimed to describe the successful implementation of a surgical technique to facilitate "SS" cases. METHODS: The cases included males and females aged 32-81 years consecutively treated between 2020 and 2023 (longest follow-up, 3.5 years). For each case, pre- and post-operative cone-beam computed tomography (Digital Imaging and Communications in Medicine files) and intraoral optical scans (IOS; STL files) were performed...

Socket wall resorption leading to a loss of surrounding bone following tooth extraction has been documented in the dental literature. The use of various socket-shield techniques has been suggested as a solution to this issue. In these approaches, the tooth root is sectioned in two, and the coronal two-thirds of the buccal root is preserved in the socket. This allows the periodontium along with the bundle and buccal bone to remain intact, thus preventing or minimizing bone remodeling. According to the literature, this procedure is highly technique sensitive, especially when it comes to sectioning the root...

BACKGROUND: The success of implants in the socket shield technique relies on stress experienced by root fragments within the socket. Although there is no consensus on optimal root fragment thickness, varying thicknesses and dynamic implant placement induce stress in various directions and degrees. This study aimed to assess biomechanical response and stress distribution across different root fragment thicknesses in the socket shield procedure. METHODS: This in vitro study was conducted to assess and compare the stress distribution on residual root structures of varying thicknesses positioned within the labial aspect of the maxillary incisor socket during immediate implant placement of standard dimensions...

PURPOSE: To evaluate bone preservation and aesthetic recovery between the socketshield technique (SST) with different labial bone plate thicknesses and the conventional immediate implant technique (CIIT). MATERIALS AND METHODS: Patients who underwent immediate implant placement in the anterior region were divided into three groups: the SST with a thick-wall phenotype (> 1 mm) (SSTA group), the SST with a thin-wall phenotype (< 1 mm) (SSTB group) and the CIIT with a thick-wall phenotype (> 1 mm) (CIIT group)...

The two presented cases of socket shield technique were done following a split mouth protocol in two patients, each received an immediate implant inserted conventionally on maxillary one side and another implant inserted applying the socket shield technique on the contralateral side. The outcomes including soft and hard tissue changes were compared clinically and radiographically. The four implants were followed for 5 years, and the outcomes were successful.

PURPOSE: To compare volumetric changes in buccal soft tissue and pink esthetic scores after immediate implant placement performed with a socket shield technique (SST) or the conventional technique (CT). MATERIALS AND METHODS: This parallel-arm, randomized controlled trial included 22 participants requiring replacement of a single maxillary incisor with an immediate implant. Immediate implants were placed via either the SST or the CT, with patients randomly allocated to one of the two groups...

Following tooth extraction, the alveolar ridge undergoes morphological and dimensional changes, including a clot formation that is gradually replaced by granulation tissue. Studies indicate that both horizontal and vertical ridge dimensions decrease after extraction; however, these changes can be mitigated through grafting with biomaterials and barrier membranes. Alveolar ridge preservation (ARP) techniques are employed to counteract bone resorption postextraction, encompassing periosteal inhibition and modified periosteal inhibition (MPI) techniques...

Extraction-site alveolar remodeling is a major concern due to negative volumetric hard and soft tissue changes that inevitably limit rehabilitation options and diminish esthetic outcomes. Surgical techniques employed to minimize alveolar dimensional changes are not always predictable. Utilizing socket-shield with immediate implant surgical procedure provides maintenance of a thin portion of the root in the vestibular area that minimizes bone resorption especially at the coronal cortical aspect. This case series assesses the dimensional changes in peri-alveolar structures via superimposition of the pre-operative and six-month post-operative 3D digital quantification of soft tissue...

OBJECTIVES: Autologous dentin grafts derived from extracted teeth have shown promise as bone graft materials for promoting bone regeneration. This retrospective case series aimed to evaluate clinical, radiographic, and histologic outcomes of using autologous dentin matrices in various bone regeneration procedures. MATERIALS AND METHODS: This case series included 26 eligible patients and encompassed 4 socket preservation cases, 5 cases of guided tissue regeneration, 5 cases of guided bone regeneration (GBR), 10 cases of sinus augmentation procedures, 2 immediate placement implants, and 2 socket shields...

Esthetics is important for any dental implant but crucial for implants in the anterior region. Restorations in this region are demanding, and the goal of re-establishing an attractive smile without revealing differences from the natural teeth is difficult to achieve. The aim of this study was to examine the clinical success of the socket-shield technique regarding soft tissue stability and overall esthetic outcome. Pink esthetic scores (PESs) were collected at two time points (T1: 6 months; T2: 6 years) by three different specialists...

The UK's National Joint Registry (NJR) and the American Joint Replacement Registry (AJRR) of 2022 revealed that total hip replacement (THR) is the most common orthopaedic joint procedure. The NJR also noted that 10-20% of hip implants require revision within 1 to 10 years. Most of these revisions are a result of aseptic loosening, dislocation, implant wear, implant fracture, and joint incompatibility, which are all caused by implant geometry disparity. The primary purpose of this review article is to analyze and evaluate the mechanics and performance factors of advancement in hip implants with novel geometries...

OBJECTIVE: Despite significant progress within implant prosthetic therapy, preserving the papilla between two adjacent implants in the esthetic zone, particularly between central and lateral incisors, remains challenging. This case series aims to report a papilla preservation approach between adjacent upper central-lateral incisor implants using the socket-shield technique. CLINICAL CONSIDERATIONS: Six patients with natural dentition received unilateral adjacent central-lateral incisor implants with different socket shield configurations...

Socket shield technique (SST) and subepithelial connective tissue graft (SCTG) following immediate implant placement with provisionalization (IIPP) had been advocated for peri-implant facial contour and gingival architecture preservation. This case report used the 3D volumetric analysis to longitudinally assess the peri-implant facial contour change before and after these procedures. The results demonstrated a comparable and acceptable preservation of peri-implant facial contour between the 2 procedures after 2 years of function...

PURPOSE: To achieve accurate socket shield preparation with newly proposed guides that are based on guiding rails and to investigate the effect of rail format (unilateral or bilateral) and rail height on the accuracy and efficiency of the guides. MATERIALS AND METHODS: Two surgical guides based on grooved rails to guide the rotary instruments were produced. The first guide was used to cut the root into a labial shield with a pre-designed form and a lingual one, while the second guide was used to reduce the socket shield to the alveolar bone crest...

The socket shield technique has been proposed as a surgical method to prevent the collapse of the buccal plate following tooth extraction, leading to excellent soft-tissue stability and long-term aesthetic outcomes. Despite its success, this technique is still not without potential risks. One of the most common complications is internal exposure of the socket shield. It can present as inflammation of the inner soft tissue with or without exposure of a portion of the shield. This case series discusses this complication's aetiology, diagnosis, treatment, management, and prevention...

OBJECTIVES: To evaluate the ridge alterations and esthetic outcome 1 year after immediate implant placement using the dual-zone (DZ) technique versus the bone shielding concept in patients with intact thin-walled sockets in the esthetic zone. MATERIAL AND METHODS: This randomized clinical trial included 26 patients with nonrestorable maxillary teeth in the esthetic zone who were randomly assigned to two groups (n = 13 each) to receive immediate implants using either the bone shielding concept or DZ...

The amputee population according to the World-Health-Organization is about 40 million. However, there is a high abandon rate of socket prostheses for the lower limb (25%-57%). The direct connection between the external prosthesis and the patient's bone makes osseointegrated prostheses for transfemoral amputees advantageous (e.g., improvement of the motor control) compared to socket prostheses, which are currently the gold standard. However, similarly to other uncemented prostheses, the osseointegrated ones are at risk of aseptic loosening and adverse bone remodelling caused by stress-shielding...

BACKGROUND: To analyze through finite element analysis the stress distribution in peri-implant bone tissues, implants, and prosthetic components induced by the socket shield (SS) technique in comparison to other techniques used to treat tooth loss. MATERIALS AND METHODS: A three-dimensional model of a superior central incisor crown supported by implant was modeled and three different placement conditions were simulated: SS - 2.0-mm-thick root dentin fragment positioned between the alveolar buccal wall and implant; heterologous bone graft (HBG) - bovine bone graft positioned the alveolar buccal wall and implant; and control (C) - implant fully placed in bone tissue of a healed alveolus...
