Socket shield

Amit Srikant Gharpure, Neel B Bhatavadekar
The recently popularised socket-shield technique involves intentional retention of a section of the remnant root at the time of immediate implant placement to preserve the buccal/proximal bone from resorption. The objective of this systematic review was to assess the literature available on the socket-shield technique and weigh its biological plausibility and long-term clinical prognosis. A Systematic Search was performed in PubMed-Medline, Embase, Web of Knowledge, Google Scholar and Cochrane Central for clinical/ animal studies up to April 2017...

Part 1 of this series introduced the partial extraction therapies as a group of techniques for ridge preservation at immediate implant placement and beneath pontic sites. The concept proposes a paradigm shift away from extract and augment toward partly retaining the tooth root to preserve the ridge and prevent buccopalatal collapse. The revolutionary socket-shield technique was introduced in 2010; however, there has been no follow-up literature to guide the clinician in terms of procedural steps. While root submergence is well established, the socket-shield and pontic shield are still in their clinical infancy and require long-term clinical data before they can be proposed as routine in everyday implant dentistry...

OBJECTIVES: Implant placement immediately after tooth extraction is often accompanied by resorption of surrounding tissues. A clinical technique was developed where the buccal portion of the root is retained to preserve the periodontal ligament and bundle bone. This technique is based on animal studies showing the potential to preserve the facial tissues utilizing this approach. The purpose of this study was to gain more insight regarding the safety of the technique with regard to biological and implant-related long-term complications and to observe the clinical appearance of the peri-implant tissues...

Background and purpose - The acetabular component has remained the weakest link in hip arthroplasty for achievement of long-term survival. One of the possible explanatory factors for acetabular failure has been acetabular stress shielding. For this, we investigated the effects of a cementless elastic socket on acetabular bone mineral density (BMD). Patients and methods - During 2008-2009, we performed a single-center prospective cohort trial on 25 patients (mean age 64 (SD 4), 18 females) in whom we implanted a cementless elastic press-fit socket...

The aim of this study was to evaluate the influence of the residual root and peri implant bone dimensions on the clinical success of the socket shield technique. Thirty-six dental implants were installed in 6 dogs. The clinical crowns of teeth P3, P4 and M1 were beheaded. Afterwards, the roots were worn down 2-3mm in apical direction until they were located at crestal level. Posterior implant beds were prepared in the center of the roots passing by 3mm apically forming 6 groups in accordance to the remaining root thickness...

Buccopalatal collapse of the postextraction ridge is a significant challenge in restorative and implant dentistry. A variety of ridge preservation techniques using tissue and augmentative materials have been proposed in the literature. A slightly different approach is to use the tooth itself. Root submergence has been reported in the literature for more than 4 decades, and it has been demonstrated that the submerged tooth root retains the periodontal tissues and preserves the bone in pontic sites or below dentures to retain the ridge...

Augmentive ridge preservation techniques aim to manage the postextraction ridge. The partial extraction of teeth may better preserve the ridge form by maintaining the bundle bone-periodontal ligament apparatus. Root submergence has been demonstrated to retain the periodontal tissues and preserve the ridge beneath dentures or fixed prostheses. The socket-shield technique entails preparing a tooth root section simultaneous to immediate implant placement and has demonstrated histologic and clinical results contributory to esthetic implant treatment...

Following the extraction of an incisor in the maxilla, resorption of the -alveolar bone always occurs, especially on the buccal side. This often indicates that in the buccocervical area, insufficient bone is present to cover the dental implant. One treatment option is to carry out a bone transplant on the buccal side prior to or during the placement of the implant. An alternative way of supporting the buccocervical gingival is to leave the buccal part of the radixin situ, the so-called socket-shield technique...

A scalloped anatomy maintained between two adjacent crowns supported by immediate implants is presented in this clinical case. This is a modified concept of the socket-shield technique, which allows preservation of the papilla due in part to preservation of interproximal root fragments. Clinical results at 11 months after implant placement are presented.

BACKGROUND: The "socket-shield technique" has shown its potential in preserving buccal tissues. However, front teeth often have to be extracted due to vertical fractures in buccolingual direction. It has not yet been investigated if the socket-shield technique can only be used with intact roots or also works with a modified shield design referring to vertical fracture lines. PURPOSE: The aim of this study was to assess histologically, clinically, and volumetrically the effect of separating the remaining buccal root segment in two pieces before immediate implant placement...

An alternative to prosthetic socket rehabilitation of patients with transfemoral amputation is realized by means of direct skeletal fixation devices. offering significant improvements in mobility and comfort. However, strain shielding due to high stiffness of these metal-based implants causes considerable and progressive bone loss. To overcome this phenomenon a new concept of a direct fixation implant, in form of a collared metallic pin articulating inside a polymer intramedullary part, was developed. In this study we used experimental and finite element techniques to assess whether the novel concept produced a more physiological strain distribution in the bone as compared to a standard titanium implant...

BACKGROUND: Loosening, femoral neck fracture, and metal ion release have been well documented after hip resurfacing arthroplasty, but impingement between the acetabular cup and the femoral neck has not. The goal of this study was to analyze radiographic findings that were presumed to represent impingement of the neck after hip resurfacing arthroplasty, and to describe the mechanism of impingement. METHODS: Of the 635 hips (579 patients) that underwent hip resurfacing arthroplasty between September 1998 and May 2008, forty hips (6...

World-to-chip (macro-to-micro) interface continues to be one of the most complicated, ineffective, and unreliable components in the development of emerging lab-on-a-chip systems involving integrated microfluidic operations. A number of irreversible (e.g., adhesive gluing) and reversible techniques (e.g., press fitting) have attempted to provide dedicated fluidic passage from standard tubing to miniature on-chip devices, none of which completely addresses the above concerns. In this paper, we present standardized adhesive-free microfluidic adaptors, referred to as Fit-to-Flow (F2F) Interconnects, to achieve reliable hermetic seal, high-density tube packing, self-aligned plug-in, reworkable connectivity, straightforward scalability and expandability, and applicability to broad lab-on-a-chip platforms; analogous to the modular plug-and-play USB architecture employed in modern electronics...

Lepidopteran larvae possess two pairs of styloconic sensilla located on the maxillary galea. These sensilla, namely the lateral and medial styloconic sensilla, are each comprised of a smaller cone, which is inserted into a style. They are thought to play an important role in host-plant selection and are the main organs involved in feeding. Ultrastructural examination of these sensilla of fifth instar Lymantria dispar (L.) larvae reveal that they are each approximately 70 um in length and 30 um in width. Each sensillum consists of a single sensory peg inserted into the socket of a large style...

AIM: Clinical studies have suggested that retaining roots of hopeless teeth may avoid tissue alterations after tooth extraction. Therefore, the objective of this proof-of-principle experiment was to histologically assess a partial root retention (socket-shield technique) in combination with immediate implant placement. MATERIAL AND METHODS: In one beagle dog, the third and fourth mandibular pre-molar were hemisected and the buccal fragment of the distal root was retained approximately 1 mm coronal to the buccal bone plate...
