The objective of this study was to evaluate the accumulation ions in blood and organs caused by titanium (Ti) metal particles a mandibular defect rats, together with description local reaction oral tissues Ti alloy debris.Twenty Sprague-Dawley rats were randomly distributed into three groups: an experimental group bone filled metallic debris obtained implantoplasty; positive control group; negative group. Thirty days after surgery, euthanized perilesional tissue surrounding removed, lungs,...

This study aimed to evaluate the efficacy and safety of a digitally guided dual technique during esthetic crown lengthening surgery. In addition, patient satisfaction patient-reported outcomes were assessed. A prospective case series was conducted. Cone-beam computed tomography intraoral scans used design surgical guides, which manufactured via 3D printing. The primary outcome accuracy, assessed by measuring distance between planned final gingival margin positions using overlapping scans....

In the field of implant dentistry there are several mechanisms by which metal particles can be released into peri-implant tissues, such as insertion, corrosion, wear, or surface decontamination techniques. The aim this study was to evaluate corrosion behavior Ti6Al4V during implantoplasty dental implants treated due periimplantitis. A standardized protocol used obtain produced polishing implants. Physicochemical and biological characterization were described in Part I, while mechanical...

This work studies the presence of Ti, Al and V metal ions Ti nanoparticles released from debris produced by implantoplasty, a surgical procedure used in clinic, rat organs.The sample preparation for total determination was carefully optimized using microsampling inserts to minimize dilution during acid attack lyophilized tissues microwave-assisted digestion method. An enzymatic method applied different tissue samples order extract titanium single-particle ICP-MS analysis.A statistically...

Implantoplasty is a mechanical decontamination technique that consists of polishing the supra-osseous component dental implant with peri-implantitis. This releases metal particles in form swarf and dust into peri-implant environment. In present vitro study, following physicochemical characterization tests were carried out: specific surface area, granulometry, contact angle, crystalline structure, morphology, ion release. Besides, cytotoxicity was turn evaluated by determining fibroblastic...

Abstract Implantoplasty is a mechanical decontamination technique that consists of removing the threads and polishing smoothing dental implant surface. During implantoplasty there large release titanium metal particles might provoke proinflammatory response reduce viability osteogenic cells. We analyze inflammatory induced by Ti6Al4V released during as-received commercially pure Ti particles. Macrophages stimulated with obtained showed an increased expression TNF-α decreased TGF-β CD206....

Background: The aim was to describe the recurrence rates of Oral Squamous Cell Papilloma (OSCP) following surgical treatment with scalpel and two different lasers (CO 2 or Er,Cr;YSGG) determine clinical histopathologic features these lesions.Material Methods: A retrospective cohort study covering a period 12 years (1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009) that included patients diagnosed OSCP treated excision performed.Data processed using SPSS 22.0 (SPPS...

Florid cemento-osseous dysplasia is a non-neoplastic fibro-osseous lesion which often has an asymptomatic slow growth. Unfortunately, these lesions are usually diagnosed through routine radiographic examination. The aim of this study was to describe the main clinical, radiological and histological characteristics two case reports with florid dysplasia.Two cases different clinical features were presented. Panoramic radiographs showed multiple radiopacities compatible in distinct areas...

The aims of this study were to describe the clinical findings patients that suffered teeth displacement into maxillary sinus, and report surgical technique used solve complication.A retrospective observational was conducted involving a sinus. Demographic data recorded from affected descriptive statistical analysis made variables.A total nine enrolled, six males (66.7%) three females (33.3%), with mean age 36.0 years (range 22-54). In five (55.5%) displaced remained asymptomatic; however,...

Implantoplasty (IP) is used in dental implants with peri-implantitis and aims to remove threads polish rough surfaces order prevent bacterial colonization. As a result of this procedure, implant strength might be compromised. We tested 20 tapered screw-shaped Ti6Al4V simulated bone loss 50%. Ten underwent IP 10 served as controls. Surface topography (Sa, Sz, Ssk, Sdr) was analyzed confocal optical microscope. Subsequently, minimum four series cyclic loads were applied servo-hydraulic...

The removal of third molars (3Ms) is the most frequent surgical procedure in field Oral Surgery. As a result, Spanish Society Surgery (SECIB) aims to create Clinical Practice Guideline (CPG) that offers evidence-based recommendations for optimal clinical practice. Specifically, CPG will focus on providing guidance regarding indications and criteria radiological diagnosis patients with 3Ms.

Background: This prospective cohort study aimed to assess the predictability and survival rates of dental implant treatment in edentulous patients while identifying potential factors contributing failure.Material Methods: A total 80 outpatients, receiving 166 implants between September 2015 November 2017 two private clinics, were included this study.Patient characteristics, surgical procedures, primary stability, prosthetic rehabilitation, failure analysis, analyzed.Results: The majority...

Background: The decision-making process about how to rehabilitate edentulous osseous defects in patients with head and neck cancer history can be complex.Even though, endosseous dental implants could considered the first choice for treating these patients, it is highly important aware of complications that might occur.The aim this report was describe clinical features mandibular fracture after placement on a irradiated patient update available information event.Case report: case describes...

To determine changes in anxiety perceived students during their first experience injecting local anaesthetic and assess the variability perception teaching/learning as surgeons patients relation to gender.This cross-sectional study was carried out on enrolled Anaesthesia Resuscitation course at University of Barcelona. A descriptive bivariate analysis using McNemar Fisher tests. The level significance set a P-value <.05.Out 85 students, total 71 responses were obtained. Overall, significant...
