Abstract:Introduction: This study aimed at testing the effect of the socket shield technique on the maintenance of the labial plate of bone and the change in position of its surrounding gingival soft tissues upon the immediate placement of 3 different dental implants systems, with a bone graft material filling the defects around the implants, followed by clinical and radiographic evaluation using the cone beam computed tomography after 4 and 12 months of loading. Materials and Methods: Three groups, 6 male patients eac… Show more

“…[ 26 ] reported the bone loss at the neck, middle, and root of the implants as 0.27 ± 0.21 mm, 0.19 ± 0.20 mm, and 0.28 ± 0.29 mm, respectively, in 10 cases of SST. Walid and Alkhodary[ 28 ] reported no significant changes in the thicknesses of the labial bone plate and absence of vertical resorption with SST during 1 year of follow-up. In a prospective nonrandomized controlled study by Xu et al .,[ 27 ] the labial bone thickness after 1 year was found to be 2.90 ± 0.64 mm in the SST group and 2.51 ± 0.69 mm with the conventional technique.…”

“…[ 40 41 42 ] Therefore, SST achieves better esthetic outcome because it reduces the alveolar bone resorption. In the majority of the included studies,[ 7 11 15 17 19 20 22 27 28 30 ] the fragment had been reduced around 1 mm coronal to the labial bone plate to retain the dentogingival fibers which seemed to increase soft tissue esthetics by maintaining the mucosal zenith at a more coronal position. [ 43 ] Furthermore, peri-implant probing in SST cases had revealed healthy conditions and volumetric analysis had shown a low degree of contour changes with effective preservation of facial tissue contours.…”

The aim of this review is to present the currently available studies on the treatment outcome of socket shield technique (SST) with an attempt to compare it with the conventional technique for immediate implant placement. An electronic search was performed using PubMed, Google Scholar, and Cochrane databases. All relevant human studies reporting the treatment outcome of SST in conjunct with immediate implant placement were included.
In vitro
studies, case reports, reviews, systematic reviews and articles not related to SST were excluded. The initial electronic database search identified 606 articles. After removing the duplicates, reading the titles and abstracts, 19 articles were eligible for full-text reading. Two case series were excluded as the specific treatment outcomes of the clinical cases were not mentioned. Further, one article was included after hand searching of the reference lists. Eighteen articles were included for the final review. These 18 articles consisted of 15 full texts and 3 abstracts. Out of them, 3 were randomized controlled trials, 7 were retrospective studies, 4 were prospective studies, 1 was a prospective case series, 1 was a prospective nonrandomized controlled study and 2 were comparative studies. This review concludes that though the implant survival rate may be comparable in SST and the conventional technique, the SST seems to perform better in terms of bone preservation, esthetic outcome, and patient satisfaction. Furthermore, further randomized clinical trials are required to generate strong evidence for recommending SST over the conventional technique for long-lasting successful treatment outcomes with immediate implants.

Partial extraction therapy (PET) is a collective concept encompassing a group of surgical techniques including socket shield, root membrane, proximal shield, pontic shield and root submergence. PET utilizes the patient’s own root structure to maintain blood supply derived from the periodontal ligament complex in order to preserve the periodontium and peri-implant tissues during restorative and implant therapy. This review aims to summarize current knowledge regarding PET techniques and present a comprehensive evaluation of human clinical studies in the literature. Two independent reviewers conducted electronic and manual searches until January 1 st , 2021 in the following electronic bibliographic databases: PubMed, EMBASE, and Dentistry & Oral Sciences Source. Grey literature was searched to identify additional candidates for potential inclusion. Articles were screened by a group of 4 reviewers using the Covidence software and synthesized. Systematic search of the literature yielded 5,714 results. 64 articles were selected for full-text assessment, of which, 42 eligible studies were included in the review. 12 studies were added to the synthesis after manual search of the reference lists. A total of 54 studies were examined in this review. In sum, PET techniques offer several clinical advantages: 1) preservation of buccal bone post-extraction and limitation of alveolar ridge resorption 2) mitigation of the need for invasive ridge augmentation procedures 3) soft tissue dimensional stability and high esthetic outcomes. Further randomized clinical studies with larger sample sizes are needed to improve understanding of the long-term clinical outcomes of PET.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
