Peri-Implant Mucosal Fenestration and Histologic Observation of Bone Xenograft Material 7-Years After Implant Installation: A Case Report.

Bone augmentation is often required before the installation of dental implants. Here, we report a case for a patient who previously received bone augmentation at the upper right jaw using a xenogenic graft, followed by successful implant installation. Seven years later, the patient presented with mucosal fenestration with bone exposure at the area and gave a history of a recent diagnosis of cutaneous lichen planus.

Long-term predictability of allogenic dermal matrix for root coverage: Three years observation period on 15 consecutive cases.

Gingival recession is an apical migration of gingival margin that is a common finding on patients with meticulous oral hygiene and periodontitis patients. Several surgical treatment techniques of gingival recession have been described. The most challenging situation is the presence of multiple adjacent recession defects.

The Osteogenetic Potential of Chitosan Coated Implant: An Study.

: Chitosan is a promising polymer that has been used for coating dental implants. However, research concerning coatings with implant surfaces other than commercially pure titanium is limited. Therefore, this study aims to clarify the chitosan material's effect with two degrees of deacetylation (DDA) as coatings for laser surface microtopographic implants.

Eighteen female Sprague-Dawley rats aged 6 weeks and weighing 300 g were used.

Histomorphometric analysis of bone regeneration using a dual layer of membranes (dPTFE placed over collagen) in fresh extraction sites: a canine model.

In untreated extraction sockets, buccal bone remodeling compromises the alveolar ridge width. The aim of this study was to histologically assess the efficacy of using a dual layer of membranes (high-density polytetrafluoroethylene [dPTFE] placed over collagen) for ridge preservation in fresh extraction sites. Eight beagle dogs were used.

Efficacy of acellular dermal matrix and coronally advanced flaps for the treatment of induced gingival recession defects: a histomorphometric study in dogs.

Background: Gingival recession (GR) defects can be treated by various methods, including acellular dermal matrix (ADM) or coronally advanced flaps (CAFs). The aim of this histomorphometric experiment is to compare the efficacy of ADM and CAF for treating GR defects in dogs.

Methods: In eight beagle dogs, a critical-size labial GR defect was surgically induced on bilateral maxillary cuspids under general anesthesia.

Efficacy of using a dual layer of membrane (dPTFE placed over collagen) for ridge preservation in fresh extraction sites: a micro-computed tomographic study in dogs.

Objective: To assess if overbuilding the buccal plate or using a dual-layer socket grafting technique prevents alveolar bone resorption and enhances final ridge width, height, and volume after tooth loss in an animal model.

Material And Methods: In eight beagle dogs bilateral second (P2)-, third (P3)-, and fourth (P4) premolars were endodontically treated. All bilateral mandibular first premolars and distal roots of P2, P3, and P4 were hemisectioned and atraumatically extracted.

Microcomputed tomographic analysis of the alveolar ridge alteration around extraction sites with and without immediate implants placement: in vivo study.

Background: The aim was to assess the alveolar ridge alteration around extraction sites with and without immediate implants according to extraction socket classification (ESC) using microcomputed tomography (micro-CT).

Material And Methods: Ten beagle dogs (mean age and weight: 24 ± 0.83 months and 13.

Efficacy of using PDGF and xenograft with or without collagen membrane for bone regeneration around immediate implants with induced dehiscence-type defects: a microcomputed tomographic study in dogs.

Background: Use of collagen membrane (CM) with xenograft and recombinant human platelet-derived growth factor (rhPDGF) in guided bone regeneration (GBR) is debatable. The aim of this microcomputed tomographic experiment was to assess the efficacy of using PDGF and xenograft (with or without CM) for GBR around immediate implants with dehiscence defects.

Methods: Ten beagle dogs underwent atraumatic bilateral second and fourth premolar extractions from both arches.

Effect of implant surface properties on peri-implant bone healing: implant stability and microcomputed tomographic analysis.

Purpose: The present study aimed to evaluate and compare two types of implants: grit-blasted and acidetched implants (SLActive) and nanometer-scale hydroxyapatite-modified implants (NanoTite).

Materials And Methods: Twenty-two SLActive and 22 NanoTite implants were inserted into the mandibles of 11 beagle dogs. The animals were divided into three groups according to healing time (group A, 2 weeks; group B, 4 weeks; group C, 8 weeks).

Surgical and implant-supported fixed prosthetic treatment of a patient with ectodermal dysplasia: a case report.

Ectodermal dysplasia (ED) is a hereditary disorder that affects ectodermal structures. The main clinical oral manifestations of ED include oligodontia and deficient alveolar ridges. This case report presents the oral rehabilitation of a 15-year-old female patient who never received an accurate diagnosis or appropriate dental care.

Esthetic soft tissue ridge augmentation around dental implant: Case report.

The aim of this case report is to present a method to correct soft tissue ridge deformity around dental implant using acellular dermal matrix (ADM). A 25-year-old female patient presented with a missing maxillary first left premolar, which had class I soft tissue defect. The missing tooth was replaced with single implant supported prosthesis and the soft tissue defect was corrected using ADM utilizing the envelop technique.

The antifungal action of different concentrations of white-colored mineral trioxide aggregate (MTA) against Candida albicans was assessed in vitro. Fresh mix of MTA was prepared at concentrations varying from 0.78 mg/ml to 50 mg/ml by dilution with 10 ml molten agar at 45 degrees C.

Guided tissue regeneration-based root coverage: meta-analysis.

Background: The goal of guided tissue regeneration-based root coverage (GTRC) is to repair gingival recession via new attachment formation. Numerous clinical trials have been conducted utilizing the concept of GTR to promote root coverage. Most GTRC studies have had relatively small sample sizes and have not utilized power calculations to determine appropriate sample size; therefore, it is difficult to draw strong conclusions from them.
