Bone assessment around the delayed dental implant with and without preformed anatomical caps: A 1-year retrospective case-control study.

Purposes: To investigate the amount of first-year peri‑implant bone loss and the development of the papillae when delayed dental implants loaded with anatomic cover screw and those underwent conventional healing protocol were compared.

Methods: Edentulous healed sites had undergone delayed implants placement. In the anatomical cap group, patients were treated with a guided tissue healing, tooth-like cross-linkable acrylic resin caps had been immediately screwed on dental implants.

The New Generation of Subperiosteal Implants for Patient-Specific Treatment of Atrophic Dental Arches: Literature Review and Two Case Reports.

Subperiosteal implants were first introduced in the early 1940s for the treatment of edentulous maxillary and mandibular arches with severe bone atrophy. After achieving widespread popularity in the 80s and 90s, this denture therapy was progressively abandoned due to significant technique limitations, including high rates of infection and the complications and difficulties with positioning implants and obtaining sufficiently extensive bone impressions. In the last two decades, digital technology has dramatically changed the world of implant dentistry.

Clinical and radiographic evaluation of transalveolar two-step osteotome-mediated sinus floor elevation versus sinus augmentation with displacement of the palatal wall in lateral direction coupled to alveolar ridge split technique: A 3-year retrospective study.

Introduction: The present study aimed to examine the middle-term effects of transcrestal double-sinus elevation (TSFE) versus alveolar/palatal split expansion technique (APS) and simultaneous implant placement in the augmented sinus.

Null Hypothesis: there were no differences between groups.

Material & Methods: Magnetoelectric device was used for bone augmentation and expansion techniques in long-standing edentulous patients with a deficiency in vertical height in the posterior maxilla (3mm to 4mm residual bone height): TSFE group, or two-stage process with a first transcrestal sinus floor augmentation and a second sinus floor elevation with immediate implant placement; APS group, or "dual split and dislocation" of the two cortical bony plates towards the sinus and palatal side.

Volume assessment of the external contour around immediate implant with or without immediate tooth-like crown provisionalization: A digital intraoral scans study.

Purposes: To examine differences between immediate and delayed dental implant loading in maxillary aesthetic areas.

Methods: In this retrospective controlled analysis, 43 subjects who underwent immediate placement of the dental implant in a post-extraction socket were ranked into either immediate (24 implants loaded with non-occlusal tooth-like profile provisional prostheses fabricated by virtual diagnostic impressions and an in-office dental milling machine) or delayed group (19 implants loaded with conventional cover screws and secondary intention healing). Intraoperatively and then four months later, scans of the external layers were acquired with an optical scanner.

Effectiveness of a Water Disinfection Method Based on Osmosis and Chlorine Dioxide for the Prevention of Microbial Contamination in Dental Practices.

In dental clinics, the infections may be acquired through contaminated devices, air, and water. Aerosolized water may contain bacteria, grown into the biofilm of dental unit waterlines (DUWLs). We evaluated a disinfection method based on water osmosis and chlorination with chlorine dioxide (O-CD), applied to DUWL of five dental clinics.

A Retrospective Digital Analysis of Contour Changing after Tooth Extraction with or without Using Less Traumatic Surgical Procedures.

Background: The present retrospective analysis aimed to compare two different single tooth extraction surgical approaches in both premolar and molar areas: less traumatic magneto-electrical versus conventional tooth extraction in minimizing the edentulous ridge volume loss.

Methods: In the present retrospective control trial, 48 patients who underwent one-tooth extraction, were allocated either to control (28 sites treated with conventional tooth extraction procedures) or test group (20 subjects treated with less traumatic tooth extraction procedures by tooth sectioning and magnetoelectric roots subluxation). Intraoperatively (during tooth extraction surgery just after the subsequent filling of the alveolar socket with the sterile fast re-absorbable gelatin sponge), and then four months later, contours of the sockets were acquired through a laser intra-oral scanner.

Effectiveness of Disinfection with Chlorine Dioxide on Respiratory Transmitted, Enteric, and Bloodborne Viruses: A Narrative Synthesis.

A viral spread occurrence such as the SARS-CoV-2 pandemic has prompted the evaluation of different disinfectants suitable for a wide range of environmental matrices. Chlorine dioxide (ClO) represents one of the most-used virucidal agents in different settings effective against both enveloped and nonenveloped viruses. This narrative synthesis is focused on the effectiveness of ClO applied in healthcare and community settings in order to eliminate respiratory transmitted, enteric, and bloodborne viruses.

Distal Displacement of Maxillary Sinus Anterior Wall Versus Conventional Sinus Lift with Lateral Access: A 3-Year Retrospective Computerized Tomography Study.

Background: The present study is designed to compare the outcomes of two sinus augmentation procedures: distal displacement of the anterior wall versus standard sinus lifting and grafting with a lateral window approach.

Methods: In the displacement group, a localized surgical fracture of the sinus floor achieved through an electromagnetic device results in the distal displacement of the anterior wall. In the filling group, sinus lifting (with lateral access) and grafting with particulate xenogeneic bone substitute was performed.

Radiological Outcomes of Bone-Level and Tissue-Level Dental Implants: Systematic Review.

: to assess the radiological marginal bone loss between bone-level or tissue-level dental implants through a systematic review of literature until September 2019. : MEDLINE, Embase and other database were searched by two independent authors including only English articles. : The search provided 1028 records and, after removing the duplicates through titles and abstracts screening, 45 full-text articles were assessed for eligibility.

Effect of Different Timings of Implant Insertion on the Bone Remodeling Volume around Patients' Maxillary Single Implants: A 2-3 Years Follow-Up.

: To investigate the middle-term effect on bone remodeling of different timings for different implant placement (immediate versus delayed). : Patients with an anterior maxillary failing tooth were treated by single-crown supported by dental implant. Subjects were retrospectively analyzed for 3 years and assigned to one of two predictor groups: nine immediate versus 10 delayed implant placement (1-2 months after tooth extraction).

Extension implants in the atrophic posterior maxilla: 1-year results of a retrospective case-series.

Background/purpose: Blade implants account for one of the most debated dental implants design in scientific literature. They have been reconsidered by clinicians since their re-classification by Food and Drug Administration in 2014.

Materials And Methods: The present study aimed to evaluate the outcome of newly manufactured extension implants in the treatment of moderate atrophic posterior maxillae.

A methodological approach to standardize and control the quality of the position and alignment of lamina implants on two-dimensional radiographs.

Objectives: We sought to validate a new method to detect the degree of correlation between simulated and real tilted blade implants as they appear on a single two-dimensional radiograph.

Methods: The angular correction factor (CF^) was defined as the coupling of two subsequent angle transformations, a set of five angular values describing the theoretical radiographic appearance of the blade implant: (1) three consecutive rotations about the axes of the blade ([Formula: see text], θ, and ψ, standing for pitch, roll, and yaw, respectively) to represent the polarization directions; (2) a two-dimensional projection defined by two angles (λ and [Formula: see text], respectively, longitude and latitude) to represent the vector of the X-ray beam intersecting the detector plate. Data of patients who received fixed prostheses supported by blade-form implants were employed to calculate a dimensional correction factor (CF°), a specific length through the major axis.

Nonsurgical Treatment of Peri-implantitis Without Eliminating Granulation Tissue: A 3-Year Study.

Objectives: The purpose of this study was to evaluate a nonsurgical approach toward peri-implantitis by means of mechanical debridement and local detoxification leaving granulation tissue into the peri-implant pockets.

Materials And Methods: An analysis was performed on the outcomes of 2 nonsurgical protocols: mechanical debridement plus chemical detoxification with 0.2% chlorhexidine and chlortetracycline hydrochloride (test), and mechanical debridement alone (control).

Pose determination of a blade implant in three dimensions from a single two-dimensional radiograph.

The aim of the study was to introduce a mathematical method to estimate the correct pose of a blade by evaluating the radiographic features obtained from a single two-dimensional image. Blade-form implant bed preparation was performed using the piezosurgery device, and placement was attained with the use of magnetic mallet. The pose determination of the blade was described by means of three consecutive rotations defined by three angles of orientation (triplet φ, θ and ψ).

Surgical techniques used in the rehabilitation of partially edentulous patients with atrophic posterior mandibles: A systematic review and meta-analysis of randomized controlled clinical trials.

Purpose: Given the lack of general consensus in the literature regarding the best method to rehabilitate partially edentulous patients with extended atrophic edentulous sites in the posterior zone of the mandible, and with a residual ridge height less than 8 mm (with or without bone augmentation procedures), the aim of this systematic review was to analyze all the relevant randomized clinical trials (RCT), and, by means of a meta-analysis of the collected data, draw some conclusions regarding the best available treatments for the rehabilitation of posterior edentulism in partially dentate mandible.

Materials And Methods: An electronic search was conducted in the MEDLINE and Cochrane Oral Health Group databases for studies published between January 2000 and September 2015 with the use of relevant keywords and hand-searching. All identified publications were screened by the authors according to the Cochrane Data Collection Form for Intervention Reviews.

Surgical Treatment of Oroantral Communications.

Background: Oroantral communication (OAC) can be defined as a pathologic space created between the maxillary sinus and the oral cavity.This communication and subsequent formation of a chronic oroantral fistula is a common complication often encountered by oral and maxillofacial surgeons.Although various techniques have been proposed in published studies, long-term successful closure of oroantral fistulas is still one of the most difficult problems confronting the surgeon working in the oral and maxillofacial region.

Langerhans' cell histiocytosis: a case report of an eosinophilic granuloma of the mandible treated with bone graft surgery and endosseous titanium implants.

Eosinophilic granuloma is the localized and most benign form of Langerhans' cell histiocytosis. The disease shows a particular predilection for the head and neck region and usually involves the skull bones, where it manifests as well-defined lytic lesions on standard radiographs. The case of an extensive lesion involving the body of the mandible in a 52-year-old man is reported.
