Rationale for vertical periodontal defects being a contraindication to the socket-shield technique.

Much has been published on the socket-shield technique since its introduction to implant dentistry in 2010. The literature reports the technique to be a viable treatment option. Investigations should hence focus on improving the treatment, identifying pitfalls, and better educating clinicians.

The root submergence technique at single tooth sites to short-span edentulous sites: A step-by-step partial extraction therapy protocol.

Submerging roots for ridge preservation was the earliest partial extraction therapy and has been described since the 1970s. Despite the approximately 47 animal and human studies published since, an updated and contemporary step-by-step protocol has not yet been provided. This technique report describes in detail how to manage submerged roots at single tooth sites and at short-span edentulous areas.

Root submergence technique as a partial extraction therapy to preserve the alveolar ridge tissues: A systematic review and appraisal of the literature.

Statement Of Problem: As socket grafting with commercially available biomaterials has become popular, reports of the root submergence technique for ridge preservation have decreased. A systematic review of this partial extraction therapy is lacking.

Purpose: The purpose of this systematic review was to review the root submergence technique as well as critically appraise the available data.

Dimensions of the dentogingival tissue in the anterior maxilla. A CBCT descriptive cross-sectional study.

Background: The characteristics of the periodontium in anterior teeth influence the outcomes and prognosis of different periodontal, implant, and restorative procedures. In the present study, CBCT images were used to determine alveolar bone thickness and, to a lesser extent, gingival thickness. The aim was to evaluate the use of CBCT to measure the dentogingival complex in the anterior maxilla.

Comparison of excess cement around implant crown margins by using 3 extraoral cementation techniques.

Statement Of Problem: Extrusion of excess cement into the subgingival area around implant-supported crowns is associated with detrimental inflammatory response, but controlling this excess material remains a challenge.

Purpose: The purpose of this in vitro study was to perform a comparative analysis of 3 extraoral cementation techniques to reduce excess extruded cementation material around implant-supported crowns.

Material And Methods: Forty-four internal connection implant replicas were embedded in acrylic resin to form the experimental model.

A decade of the socket-shield technique: a step-by-step partial extraction therapy protocol.

Ten years have passed since Hürzeler and coworkers first introduced the socket-shield technique. Much has developed and evolved with regard to partial extraction therapy, a collective concept of utilizing the patient's own tooth root to preserve the periodontium and peri-implant tissue. The specifications, steps, instrumentation, and procedures discussed in this article are the result of extensive experience in refining the socket-shield technique as we know it today.

Hyperplastic Response Following Soft Tissue Augmentation in the Esthetic Zone.

Introduction: The indications for augmentation of gingival tissue by connective tissue graft (CTG) are numerous. The techniques are widely adopted with extensive literature reporting high success. Harvest techniques include the mid to anterior palate, versus the posterior palate and tuberosity.

The socket-shield technique at molar sites: A proof-of-principle technique report.

The socket-shield technique for avoiding postextraction tissue alteration was first described in 2010. The technique was developed for hopeless teeth in anterior esthetic sites but has not yet been described for molar sites. Managing postextractive ridge changes in the posterior region by prevention or regeneration remains a challenge.

Prosthetic management of implants placed with the socket-shield technique.

Partial extraction therapies, such as the socket-shield technique, use the patient's tooth tissues and periodontium to preserve the alveolar ridge and limit postextraction resorption. Internal exposure through the overlying peri-implant mucosa has been reported as the most common complication, suggesting that the preparation technique requires modification. This technique report describes the prosthetic management of the socket-shield technique, emphasizing preparation of the socket-shield to the bone crest, and the creation of an S-shape prosthetic emergence profile to support maximal soft tissue infill.

Esthetic tunnel exposure: A combination technique for peri-implant soft tissue development at second-stage surgery.

An esthetically pleasing result is the product of both prosthetic excellence and the health and quality of the soft tissue that frames the restoration. Management of the peri-implant coronal soft tissue is key to the ultimate success of treatment. This technique report describes an alternative, novel approach, combining established concepts and methods into a single technique to improve esthetic results.

Human Histologic Evidence of New Bone Formation and Osseointegration Between Root Dentin (Unplanned Socket-Shield) and Dental Implant: Case Report.

The socket-shield technique described 7 years ago has since grown in its reporting in the literature as a valid method of ridge preservation at immediate implant placement. To date, large clinical cohorts with up-to-4-year follow-up have been reported. Additionally, evidence of tissue histology at the dental implant and socket-shield has been demonstrated in the animal model.

Radial plane tooth position and bone wall dimensions in the anterior maxilla: A CBCT classification for immediate implant placement.

Statement Of Problem: The biological and esthetic challenge of the post-extraction ridge is relevant to restorative implant dentistry, most significantly in the anterior esthetic zone. Previous authors have discussed facial bone wall dimensions and classified their variations. A reclassification may be pertinent.

A retrospective evaluation of 128 socket-shield cases in the esthetic zone and posterior sites: Partial extraction therapy with up to 4 years follow-up.

Objectives: Tooth loss results in an inevitable alveolar ridge reduction. This has established a cautionary approach to extract, wait, augment, and insert the implant, in lieu of immediate placement. However, saving the tooth or part of it whenever possible is more conservative and supports the vital periodontal tissue buccofacial to an implant.

Partial Extraction Therapies (PET) Part 2: Procedures and Technical Aspects.

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.

Partial Extraction Therapies (PET) Part 1: Maintaining Alveolar Ridge Contour at Pontic and Immediate Implant Sites.

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.

The Palatal Bone Block Graft for Onlay Grafting Combined with Maxillary Implant Placement: A Case Series.

The aim of this study was to introduce an intraoral bone block harvesting technique--the palatal bone block graft (PBBG)--as an alternative harvest site for autogenous bone blocks. The PBBG technique was used to onlay graft esthetic zone defects simultaneous to implant placement in five patients. Measurable objectives were used to evaluate outcomes, and treatment was reassessed at up to 6 years.

The Pontic-Shield: Partial Extraction Therapy for Ridge Preservation and Pontic Site Development.

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.

Choukroun Platelet-Rich Fibrin as an Autogenous Graft Biomaterial in Preimplant Surgery: Results of a Preliminary Randomized, Human Histomorphometric, Split-Mouth Study.

This study aimed to test the null hypothesis that platelet-rich fibrin (PRF), as an immediate postextraction graft material, produces bone that is histomorphometrically no different than bone derived from healing without intervention. The authors compared split-mouth human bone biopsy specimens derived from PRF with bone that had healed without intervention. Eight human bone biopsies were successfully harvested from four patients.

Implant Injury Case Series and Review of the Literature Part 1: Inferior Alveolar Nerve Injury.

Injury to adjacent structures is an unfortunate and avoidable outcome of oral implant placement surgery. Paramount among these is perforation into paranasal sinus; into neighboring tooth root; through cortical plate; and into vessels, canals, and, most importantly, nerves. In most cases, injudicious oral implant placement can be attributed to poor treatment planning.

Dental students' motivations for their career choice: an international investigative report.

This study's aim was to investigate on an international scale the reasons why individuals are currently choosing dentistry as a career. An observational, descriptive, cross-sectional study was conducted on a cohort of first-year dental students from thirteen countries on six continents in 2011-12 (n=711). Participants completed the Du Toit Questionnaire for Health Workers and Students, designed for this study, to disclose the reason(s) why they chose a career in dentistry.
