Abstract Background Alveolar bone resorption and labial plate reduction follow teeth extraction due to the deficiency of blood supply, derived from loss periodontal ligaments, hence socket shield technique was introduced preserve ligaments related perfusion. Purpose The study aimed compare vertical horizontal changes buccal cortical plates, encountered after utilizing with immediate temporization vs an implant placement temporization, analyzing differences stability pink esthetic score evaluation between both techniques. Materials Methods A total 40 dental implants were placed in maxillary zone, 20 using temporization; group immediately control group. All patients received 6 months postoperative CBCT assess dimensional plates. Implant quotients (ISQs) scores measured at time postoperatively. Results loss; ranged 0 to0.26 (0.15) mm 0.03 to0.44 (0.32) for groups, respectively. 0.11 0.55 (0.31) 0.25 1.51 (0.7) ISQ increased 68.6 ± 3.81 76.7 3.49, while it 66.4 5.64 75 4.4.

Abstract The aim of the present study was to establish efficacy socket‐shield technique (SST) for stabilization facial gingival and osseous architecture. An electronic search including Cochrane databases, EBSCOhost, Medline/PubMed Web Science performed. Articles related SST placing dental implants were included. abstracts not written in English excluded. initial literature resulted 113 articles questions raised. Hand searching journals cross‐referencing within selected 1 more paper. Finally, 20 full texts abstract article included systematic review: 11 case reports, 6 series, human randomized control trial (RCT), technical report 2 animal RCT. Recent modifications SST, along with long follow‐up studies increased sample size, provided promising results. This review still recommends that should be used routine clinical practise until a higher level evidence established. Further RCT on are required this technique.

Published: March 21, 2024

Abstract Background The success of implants in the socket shield technique relies on stress experienced by root fragments within socket. Although there is no consensus optimal fragment thickness, varying thicknesses and dynamic implant placement induce various directions degrees. This study aimed to assess biomechanical response distribution across different procedure. Methods vitro was conducted compare residual structures positioned labial aspect maxillary incisor during immediate standard dimensions. procedure involved applying an insertional torque 40 Ncm, analysis using finite element software.

Published: Feb. 12, 2017

Extraction-socket resorption is considered a major problem that can limit implantological rehabilitation options and compromise the esthetic outcome. Surgical techniques to reduce remodeling are of restricted predictability commonly require several surgical interventions grafting. This increases treatment cost places physical psychological strain on patient. clinical case report presents replacement an upper canine using socket-shield technique (SST) with CAD/CAM guide, resulting in predictable, high esthetic, functional result.The SST alternative approach curbing by retaining facial part root during tooth extraction. An immediately placed implant supports fragment, preventing collapse buccal wall. The digital precision planning combination guide benefits patients preserving their tissue architecture causing only insignificant trauma. Furthermore, reduces number prosthetic required one each for pre-operative planning, procedures, rehabilitation.The socket shield minimally invasive offers clinicians multiple benefits.The represents intervene processes maintenance immediate placement fragment thereby prevents associated fabricated amount appointments, due fabrication definitive restoration existing model. Therefore, no further necessary appointments apart from first second treatment, third rehabilitation. (J Esthet Restor Dent 29:93-101, 2017).

The socket-shield technique: a critical literature review

International Journal of Implant Dentistry, Journal Year: 2020, Volume and Issue: 6(1)

Published: Sept. 6, 2020

Dental implants have become a standard treatment in the replacement of missing teeth. After tooth extraction and implant placement, resorption buccal bundle bone can pose significant complication with often very negative cosmetic impacts. Studies shown that if dental root remains alveolar process, is minimal. However, to date, deliberate retention roots preserve has not been routinely used implantology.This study aims collect evaluate present knowledge regard socket-shield technique as described by Hurzeler et al. (J Clin Periodontol 37(9):855-62, 2010). A PubMed database search ( www.ncbi.nlm.nih.gov/pubmed ) was conducted identify relevant publication.The initial returned 229 results. screening abstracts, 13 articles were downloaded further scrutinised. Twelve studies found meet inclusion exclusion criteria.Whilst potentially offers promising outcomes, reducing need for invasive grafts around aesthetic zone, clinical data support this limited. The limited available compromised lack well-designed prospective randomised controlled studies. existing case reports are scientific value. Retrospective exist numbers but inconsistent design. At stage, it unclear whether will provide stable long-time outcome.
