CBCT analysis of mandibular incisor area and feasibility of immediate implant placement. An alveolar housing study.

Background: Immediate implant placement (IIP) has shown predictable outcomes when specific requirements are met. The aim of the present study was to radiographically evaluate the dimensions of mandibular incisors and the alveolar bone to further determine the feasibility of IIP in this area.

Materials And Methods: A total of 404 intact mandibular incisor CBCT images from 101 patients (42 males, 59 females; mean age 49 ± 16.

Transferring emergence profile and position of interim restorative implant fixture. A novel digital technique.

The present technical article describes a protocol to digitally reproduce the emergence profile of an interim implant prosthesis (IP) and to transfer its macrogeometry into the definitive restoration. The purpose of this protocol was to minimize alterations in the gingival architecture developed during the interim restorative phase of a single implant that could potentially jeopardize its esthetic outcome. The process included obtaining an intraoral scan with the interim IP in situ, a duplicate of this intraoral scan that was used to capture the exact position of the implant, and an extraoral scan of the prosthesis.

Guided Bone Regeneration: Novel Use of Fixation Screws as an Alternative to Using the Buccoapical Periosteum for Membrane Stabilization With Sutures-Two Case Reports.

Guided bone regeneration (GBR) requires a stable graft-membrane complex. This article presents a novel technique that uses membrane fixation screws to serve as anchors for membrane stabilization sutures without the need for periosteal dissection and biting of the buccoapical periosteum. This technique may be a viable alternative when there is a preference to avoid the complexities of periosteal suturing and direct membrane fixation using tacks or screws.

Use of a Sugar-Crosslinked Collagen Membrane in Conjunction With a Dehydrated Amnion/Chorion Membrane for Guided Bone Regeneration Around Immediate Implants.

Several bioabsorbable membranes have been proposed to exclude soft-tissue ingrowth and to stabilize the bone graft when guided bone regeneration (GBR) is performed. The properties of the various membranes differ slightly due to variances in composition and manufacturing processes affecting their handling and suitability for specific techniques. The aim of this article is to present a technique to perform GBR with the use of a sugar-crosslinked absorbable collagen membrane in conjunction with a dehydrated amnion/chorion membrane (dHACM).

Flapless Extraction Socket Healing Around an Immediate Implant Placed into a Mandibular Molar Site Without the Use of Regenerative Materials: A Case Report.

The aim of this case report is to expand on previous studies of flapless immediate implant placement in sites with a large gap distance, without the application of regenerative materials. In this case report, an immediate implant was placed in a fresh molar extraction site with a large gap distance from the implant surface to the socket walls without the use of a bone graft, membrane, or coronal flap advancement for primary closure. Clinical healing was consistent with spontaneous extraction socket healing.

A modified ridge Expansion technique in the maxilla.

Localized ridge expansion of a deficient edentulous maxillary alveolar ridge segment is a useful technique when the goal of surgery is to provide an increase in ridge width as a means of establishing an adequate alveolar crest capable of receiving endosseous implants. The purpose of this article is to describe several modifications to the original ridge-splitting technique for deficient maxillary ridges. These modifications include full-thickness flap reflection, elimination of vertical intraosseous incisions, and simultaneous incorporation of guided bone regeneration.

Titanium mesh as an alternative to a membrane for ridge augmentation.

Purpose: The purpose of the present study was to determine the rate and extent of complications associated with using titanium mesh for bone regeneration and to identify which factors might be associated with postoperative complications, such as infection, soft tissue exposure, and graft failure.

Materials And Methods: A retrospective study design was used to analyze the treatment outcomes of 27 consecutive surgical sites in the maxilla and mandible that were treated with bone grafting in conjunction with fixation of titanium mesh. The primary study variable was whether the surgical sites treated with titanium mesh presented with any postoperative complications such as exposure of the titanium mesh and/or graft failure.

Effect of scaling and root planing on alveolar bone as measured by subtraction radiography.

Background: Scaling and root planing of diseased periodontal pockets is fundamental to the treatment of periodontal disease. Although various clinical parameters have been used to assess the efficacy of this therapy, radiographic analysis of changes in bone density following scaling and root planing has not been extensively researched. In this study, digital subtraction radiography was used to analyze changes that occurred in the periodontal hard tissues following scaling and root planing.

Introduction to the SES technique: a composite of surgical modifications which simplify the subepithelial connective tissue graft technique.

The subepithelial connective tissue graft has been a successful procedure when the primary goal of surgery is to obtain root coverage. A multitude of authors have described variations of the original technique that have the potential to decrease morbidity and increase the overall success of the procedure. This article describes the SES modifications, which consist of scooping horizontal incisions, elevating an envelope flap, and closing with a sling suture.
