Soft Tissue Contours at Pontic Sites With or Without Soft Tissue Grafting-A 15-Year Follow-Up of a Controlled Clinical Study.

Objectives: To report on soft tissue contour changes at pontic sites with or without soft tissue grafting over an observation period of 15 years.

Methods: Fourteen patients received a fixed dental prosthesis (FDP) in the posterior zone in a controlled clinical study and were available at the 15-year follow-up. Eight patients received a subepithelial connective tissue graft in the pontic area (test) while six received the FDP without soft tissue grafting (control).

Early implant placement in sites with ridge preservation or spontaneous healing: histologic, profilometric, and CBCT analyses of an exploratory RCT.

Purpose: The aim of this study was to compare changes in soft and hard tissue and the histologic composition following early implant placement in sites with alveolar ridge preservation or spontaneous healing (SH), as well as implant performance up to 1 year after crown insertion.

Methods: Thirty-five patients with either intact buccal bone plates or dehiscence of up to 50% following single-tooth extraction of incisors, canines, or premolars were included in the study. They were randomly assigned to undergo one of three procedures: deproteinized bovine bone mineral with 10% collagen (DBBM-C) covered by a collagen matrix (DBBM-C/CM), DBBM-C alone, or SH.

Polydioxanone Dome Technique for Guided Bone Regeneration: Surgical Technique and Results up to 72 Months of Follow-up.

This study aimed to describe the step-by-step procedure of the polydioxanone dome technique associated with guided bone regeneration (GBR) and to report the results up to 72 months after implant loading. Patients with maxillary horizontal bone defects (< 5 mm residual width, confirmed by CBCT scan) were treated with the proposed intervention. During the GBR procedure, four bone perforations were strategically prepared in a roughly square configuration.

Soft tissue contour changes at implant sites with or without soft tissue grafting in the esthetic zone: A retrospective case-control study with a 12-year follow-up.

Objectives: To evaluate the volumetric changes and peri-implant health at implant sites with and without previous soft tissue grafting over a 12-year observation period.

Materials And Methods: Eighteen patients received dental implants and simultaneously guided bone regeneration in the esthetic zone (15-25) for dental rehabilitation. Three months following implant placement, 8 patients (test) received an additional subepithelial connective tissue graft, whereas 10 patients (control) did not receive any additional treatment.

Minimal invasiveness at dental implant placement: A systematic review with meta-analyses on flapless fully guided surgery.

Flapless and fully guided implant placement has the potential to maximize efficacy outcomes and at the same time to minimize surgical invasiveness. The aim of the current systematic review was to answer the following PICO question: "In adult human subjects undergoing dental implant placement (P), is minimally invasive flapless computer-aided fully guided (either dynamic or static computer-aided implant placement (sCAIP)) (I) superior to flapped conventional (free-handed implant placement (FHIP) or cast-based/drill partially guided implant placement (dPGIP)) surgery (C), in terms of efficacy, patient morbidity, long-term prognosis, and costs (O)?" Randomized clinical trials (RCTs) fulfilling specific inclusion criteria established to answer the PICO question were included. Two review authors independently searched for eligible studies, screened the titles and abstracts, performed full-text analysis, extracted the data from the published reports, and performed the risk of bias assessment.

Clinical performance of short versus standard dental implants in vertically augmented bone: an overview of systematic reviews.

Objective: To answer the question: What do we know so far about the clinical performance of short implants (≤ 7 mm) when compared to standard length implants in vertically augmented bone, as well as which is the overall confidence of the systematic reviews (SRs) about this topic?

Materials And Methods: An overview of SRs was conducted. The searches were performed in six electronic databases and grey literature. SRs about short (≤ 7 mm) versus standard dental implants performance in vertically augmented bone were included.

Optical Behavior of Zirconia-Based Restorations Over Teeth and Implants in the Esthetic Zone: A Clinical Report.

While various zirconia-based alternatives are available today for the restoration of teeth and implants in the esthetic zone, each treatment approach could result in different optical behavior. To clinically demonstrate these differences, this case report describes a rehabilitation in the esthetic zone using several options of teeth- and implant-supported restorations. Conventional veneered zirconia crowns, high-translucent monolithic zirconia crowns, and minimally veneered high-translucent zirconia crowns were proposed and assessed under different light sources before cementation.

Employment of U-Shape Technique at Reentry Surgery for Papillae Coronal Migration on the Rehabilitation of Anterior Single Implant: 3-Year Follow-Up Case Report.

Introduction: The rehabilitation of a maxillary single dental implant represents a great challenge at clinical practice. Harmony among the implant-supported crown and adjacent teeth is required in which concerns pink and white esthetics. The aim of the present case report is to depict a multidisciplinary treatment in which the U-shape flap technique for papillae preservation at second stage surgery was used.

Peri-implant tissue management after immediate implant placement using a customized healing abutment.

Objective: The unavoidable extraction of teeth in the esthetic area can be overcome through different treatment modalities. Recently, immediate implants appeared as a minimally invasive approach to resolving these cases; however, immediate implant loading is not always possible or indicated. In these cases, an innovative approach through customized healing abutments could be used to preserve the soft tissue contour, eliminating the need for reopening surgery and the use of provisional restorations to condition the mucosal contour.

Adhesion behavior of conventional and high-translucent zirconia: Effect of surface conditioning methods and aging using an experimental methodology.

Objective: Evaluate the adhesive behavior of conventional and high-translucent zirconia after surface conditioning and hydrothermal aging.

Materials And Methods: Conventional (ZrC) and high-translucent zirconia (ZrT) specimens were divided into six groups: without surface treatment (ZrC and ZrT), air-borne particle abrasion with 50-μm Al O sized particles (ZrC-AO and ZrT-AO), and tribochemical treatment with 30-μm silica modified Al O sized particles (ZrC-T and ZrT-T). Zirconia specimens were treated using an MDP-containing universal adhesive and bonded to two resins blocks with an adhesive luting cement.

Fixed and Removable Full-Arch Restorations Supported by Short (≤ 8-mm) Dental Implants In the Mandible: A Systematic Review and Meta-Analysis.

Purpose: To evaluate, through a systematic review of the literature, the published data regarding marginal bone loss, implant failure proportion, biologic and prosthetic complications, and risk factors associated with short (≤ 8-mm) implants supporting fixed or removable full-arch restorations in the edentulous mandible.

Materials And Methods: Two reviewers performed a search of five databases, with handsearching through the reference lists and grey literature. Controlled clinical trials and prospective cohort studies were selected in a two-phase process.

Esthetic and functional rehabilitation of bilateral congenital absence of maxillary lateral incisors: Minimally invasive surgical and prosthetic approach.

Objective: Congenital absence of maxillary lateral incisors is a frequent clinical challenge which must be solved by a multidisciplinary approach in order to obtain an esthetic and functional restorative treatment. Noninvasive treatments, that are in accordance with the patients' expectations, should be the first therapeutic alternative. If the deciduous tooth is present, minimally invasive dental extraction followed by immediate dental implant placement and provisional restoration is indicated.

Background: Different disinfectant solutions or medications are indicated prior fiber post bonding procedures.The aim was to evaluate the effect of different pretreatments of root canal on the bond strength of a fiber post luted to dentin with self-adhesive resin cement.

Material And Methods: Forty-eight single-rooted mandibular premolars were endodontically treated and prepared to receive fiber posts.
