Objectives: To examine ridge dimensional changes and histologic parameters of healing when ridge preservation (RP) was performed at molar sites using dense polytetrafluoroethylene (dPTFE) membrane alone, without a bone graft.

Material And Methods: Eighteen patients had molar extraction and RP using dPTFE membrane alone. Ridge dimensions were measured using two standardized cone beam computerized tomography (CBCT) scans taken within 72 h and 3 months following extraction.

Impact of different surgical protocols on dimensional changes of free soft tissue autografts: A randomized controlled trial.

Background: To determine if there is a difference in the amount of shrinkage during healing of free soft tissue autografts (FSTAs) using different surgical techniques-suturing the vestibular flap margin apically to the base of the recipient bed versus leaving the flap margin free and unsutured.

Methods: Twenty-eight patients with mucogingival defects requiring FSTAs were recruited and enrolled in the study. Patients were randomized into test and control groups (14 per group) and received ≥1 FSTAs on non-molar mandibular teeth.

Management of Thick and Thin Periodontal Phenotypes for Immediate Dental Implants in the Esthetic Zone: A Controlled Clinical Trial.

The goal of the study was to compare the outcome of immediate single-implant placement in esthetic sites of patients with thick or thin tissue phenotypes. Forty-one patients underwent implant surgery with guided bone regeneration including peri-implant gap and overcontour grafting. A connective tissue graft was added only for patients with a thin tissue phenotype.

Purpose: The aim of this study was to evaluate the performance of implants placed for 5 years in grafted vs nongrafted sinuses in relation to crown-to-implant ratio. The measurements of crown and implant lengths took into account changes in both endo-sinus and crestal bone levels over 5 years.

Materials And Methods: Enrolled patients required one or two implants in at least one sinus and presented a residual bone height of posterior maxilla ≤ 4 mm.

Healing at Molar Extraction Sites Using Freeze-Dried Bone Allograft and Collagen Wound Dressing: Case Series and Three-Arm Analyses.

Purpose: Ridge preservation limits dimensional changes after tooth extraction. However, it is still unclear if using a membrane may be advantageous over a collagen wound dressing. Therefore, the goal of this report was to evaluate the outcomes of ridge preservation using freeze-dried bone allograft with a collagen wound dressing.

Evaluation of healing at molar extraction sites with and without ridge preservation: A three-arm histologic analysis.

Background: Little evidence is available regarding the benefit of ridge preservation (RP) at molar sites. The primary objective of this three-arm cohort study was to histologically compare the healing outcome between natural healing after molar tooth extraction and two different techniques of RP using freeze-dried bone allograft (FDBA) and a nonresorbable dense polytetrafluoroethylene (dPTFE) membrane, or an absorbable collagen sponge as a barrier.

Methods: Seventy-nine patients requiring extraction and delayed implant placement were placed into three groups: extraction alone (control); ridge preserved using FDBA; and either dPTFE (Test1) or collagen sponge (Test2).

Transferring subgingival contours around implants and the intaglio surface of the pontic to definitive digital casts by using an intraoral scanner: A technique.

The accurate transfer of the subgingival contours of implant-supported restorations and pontics is essential for providing the dental technician with the necessary information to fabricate an optimal definitive fixed dental prosthesis. However, once the interim restoration is removed to make an impression, the subgingival tissue, which is no longer physically supported, tends to collapse. This digital intraoral and extraoral scanning technique offers a way to transfer the subgingival contours and intaglio surface of the interim restoration to the definitive restoration.

Materials And Methods: This multicenter study included 50 patients in need of a single tooth replacement in the anterior (canine to canine) or premolar region of the mandible or maxilla. Patients were included if the site could accommodate a 4.

Immediate loading vs. early/conventional loading of immediately placed implants in partially edentulous patients from the patients' perspective: A systematic review.

Objectives: This systematic review aimed at answering the following PICO question: In patients receiving immediate (Type 1) implant placement, how does immediate compare to early or conventional loading in terms of Patient-Reported Outcome Measures (PROMs)?

All levels of evidence including randomized controlled trials, prospective and retrospective cohort studies, and case series of at least five patients were considered for possible inclusion. An additional manual search was performed by screening the reference lists of relevant studies and systematic reviews published up to May 2017.

Group 3 ITI Consensus Report: Patient-reported outcome measures associated with implant dentistry.

Objectives: The aim of Working Group 3 was to focus on three topics that were assessed using patient-reported outcome measures (PROMs). These topics included the following: (a) the aesthetics of tooth and implant-supported fixed dental prostheses focusing on partially edentulous patients, (b) a comparison of fixed and removable implant-retained prostheses for edentulous populations, and (c) immediate versus early/conventional loading of immediately placed implants in partially edentate patients. PROMs include ratings of satisfaction and oral health-related quality of life (QHRQoL), as well as other indicators, that is, pain, general health-related quality of life (e.

Peri-implant diseases and conditions: Consensus report of workgroup 4 of the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions.

A classification for peri-implant diseases and conditions was presented.

This systematic review considers the evidence from animal studies evaluating the effectiveness of mesenchymal stem cells (MSC) in the treatment of intraoral peri-implant defects. MEDLINE, EMBASE, and LILACS databases were searched for quantitative preclinical controlled animal model studies that evaluated the effect of MSC on bone healing at intraoral peri-implant bone defects. The primary outcome was the amount of (re-)osseointegration reported as bone-to-implant contact in the defect area.

Periodontal Biotype: Gingival Thickness as It Relates to Probe Visibility and Buccal Plate Thickness.

Background: Probe visibility is the clinical gold standard to discriminate thick from thin biotype but is prone to subjective interpretation. The primary objective of this study is to determine at what objective gingival thickness the probe becomes invisible through the tissue. A secondary objective is to compare mean buccal plate thickness between thick and thin biotypes as determined by probe visibility.

Formulating a global prognosis and treatment plan for the periodontally compromised patient: a reconstructive vs. an adaptive approach.

The clinician faces treatment planning challenges when patients present with generalized severe chronic periodontitis that may result in tooth loss. This article provides a treatment planning discussion along with approaches for treating such patients. It presents the clinical question: What is the best means for approaching treatment planning in a patient with severe periodontitis requiring extraction and replacement of some teeth? Two treatment approaches are discussed—a reconstructive approach versus an adaptive one—both of which have an end goal of achieving periodontal health and occlusal stability, and each has its own advantages and disadvantages.
