Is the postoperative discomfort after connective tissue harvesting from the palate influenced by the use of a bipolar coagulator? A randomized controlled trial.

Objectives: This study aimed to determine the effect of the use of a bipolar coagulator on postoperative pain and complications when used during connective tissue harvesting from the palate.

Material And Methods: A randomized controlled clinical trial was conducted with 57 sequential patients requiring a connective tissue graft for periodontal or implant surgery. All samples were harvested superficially and de-epithelized outside the mouth.

Framework Fracture of Zirconia Supported Full Arch Implant Rehabilitation: A Retrospective Evaluation of Cantilever Length and Distal Cross-Sectional Connection Area in 140 Patients Over an Up-To-7 Year Follow-Up Period.

Purpose: To evaluate the relationship between different dimensional parameters in implant-supported monolithic zirconia fixed complete dental prostheses (IFCDPs) and the incidence of framework fracture in a large sample of cases in vivo.

Materials And Methods: This retrospective observational study evaluated all patients rehabilitated with screw-retained zirconia IFCDPs between January 2013 and April 2019 at a private practice. The minimum follow-up period was 1 year after occlusal loading.

Three-Year Evaluation of the Influence of Implant Surfaces on Implant Failure and Peri-implantitis: A Double-Blind Randomized Controlled Trial with Split-Mouth Design.

Purpose: To compare the onset of peri-implantitis, incidence of failure, and peri-implant marginal bone level changes between implants with a roughened surface and those with a machined/turned surface.

Materials And Methods: All patients needing two dental implants of the same size on the left and right sides of the same arch, and not scheduled for immediate loading, were enrolled between October 2012 and February 2016. The patients were randomly allocated either to Nobel Biocare MKIII or Sweden & Martina Outlink2.

Immediate implant placement and loading in the esthetic area when the buccal socket wall is significantly damaged.

Objectives: Recent clinical recommendations contraindicate immediate implant placement when the socket buccal bone plate is significantly damaged. The connective tissue graft (CTG) is increasingly being used in implant therapy and can replace periodontal defects lacking bone wall in periodontal regenerative surgery. Therefore, CTG could be used to allow immediate implant placement and loading even when the buccal socket wall is damaged, facilitating graft material stability.

Jawbone remodeling: a conceptual study based on Synchrotron High-resolution Tomography.

One of the most important aspects of bone remodeling is the constant turnover mainly driven by the mechanical loading stimulus. The remodeling process produces changes not only in the bone microarchitecture but also in the density distribution of the mineralized matrix - i.e.

Esthetic treatment of alveolar ridge atrophy in the anterior maxilla via connective tissue graft performed simultaneously with implant placement: A three-case series.

Objective: The mere osseointegration of an implant should no longer be considered a satisfactory criterion for success. Tooth extraction itself and, more importantly, possible local comorbidities such as periodontal or endodontic diseases, cause a reduction in the gingival volume of the edentulous site due to bone atrophy. This reduced volume must be treated and resolved to obtain a satisfactory esthetic result, which is an essential factor for successful implant rehabilitation.

Histologic and Radiographic Analysis of Nonhealing Extraction Sockets Treated with Bio-Oss Collagen After a 4-Month Healing Period: A Prospective Descriptive Study in Humans.

Healing of extraction sockets may sometimes result in formation of fibrous tissue instead of bone, even after 4 months, an occurrence that may hinder implant placement. The aim of this preliminary observational study was to histologically evaluate quality and amount of bone regeneration after treating nonhealing sockets with a bovine-derived xenograft enriched with porcine collagen (Bio-Oss Collagen, Geistlich) without barrier membranes. Biopsy specimens were collected during implant placement, 4 months after grafting.

Evidence of earlier thyroid dysfunction in newly diagnosed oral lichen planus patients: a hint for endocrinologists.

The association between oral lichen planus (OLP) and hypothyroidism has been debated with conflicting results: some authors detected a statistically significant association between these two, while others did not confirm it. The aim of this study was to evaluate the thyroid status in patients with newly diagnosed OLP to test the null hypothesis that thyroid disease is not associated with an increased incidence of oral lesions, with a prospective case-control approach. A total of 549 patients have been evaluated, of whom 355 were female.

Adhesive esthetic treatment of non-syndromic maxillary anterior microdontia in young high-demanding patients: a case series.

Background: Microdontia of the maxillary anterior teeth occurs quite frequently but is poorly documented. The literature describes several treatment choices, which are often focused on an orthodontic approach rather than a restorative one. The latest trends in restorative dentistry and the new ceramic materials, such as lithium disilicate, allow clinicians to perform esthetic rehabilitations based on microinvasive approaches that are most appropriate for younger patients.

Is a high level of total cholesterol a risk factor for dental implants or bone grafting failure? A retrospective cohort study on 227 patients.

Purpose: This study aims to verify the effect of hypercholeresterolaemia on implant and bone augmentation failures.

Materials And Methods: A retrospective cohort study was conducted on 268 sequential patients scheduled for implant and bone augmentation surgery under conscious sedation in a private practice. Total serum cholesterol (TC) levels were assessed via blood tests before surgery.

Clinical attachment level gain and three-year maintenance of a maxillary incisor with 100% bone loss: A case report.

This case report discusses a patient suffering from chronic periodontal disease and diagnosed with a hopeless central incisor. The intention was to show the possibility of gaining new clinical attachment via regenerative surgery in a tooth with 100% bone loss around the root. Treatment of hopeless and questionable teeth in periodontal patients has become an ideological matter.

Treatment of a case of serious occlusal instability associated with TMDs through a modern mini-invasive approach.

Background: The latest trends in restorative dentistry are guided both by esthetic and mini-invasive procedures. New ceramic materials, such as lithium disilicate, allow the clinician to obtain invisible restorations with a minimum preparation thickness.

Summary: A young female patient presented at our practice with left temporomandibular closed locking and uncomfortable occlusal instability.

Conservative Nonsurgical Treatment of Class 4 Invasive Cervical Resorption: A Case Series.

External cervical resorption, also called invasive cervical resorption (ICR), is a pathological process difficult to diagnose that causes a progressive replacement of dentin by granulation tissue and results in complete tooth destruction. According to the literature, class 4 ICR can be expected to have success rates of 12.5% if treated.

Single preoperative dose of prophylactic amoxicillin versus a 2-day postoperative course in dental implant surgery: A two-centre randomised controlled trial.

Purpose: To evaluate the difference between a single preoperative dose versus an additional two-day postoperative course of oral amoxicillin in patients undergoing conventional dental implant placement.

Materials And Methods: Two dentists in two different private practices conducted this study. One hour prior to surgery, patients had to take a single prophylactic antibiotic dose, consisting of 2 g of amoxicillin orally; after implant placement, patients were randomly allocated to two different groups: protocol A (no other antibiotic administration) and protocol B, (1 g of amoxicillin in the evening of the day of surgery and 1 g twice a day for the 2 days after).

The connective tissue graft wall technique and enamel matrix derivative to improve root coverage and clinical attachment levels in Miller Class IV gingival recession.

The case reports in this article describe a surgical approach for improving root coverage and clinical attachment levels in Miller Class IV gingival recessions. Two gingival recessions affecting maxillary and mandibular lateral incisors associated with severe interdental hard and soft tissue loss were treated. The surgical technique consisted of a connective tissue graft (CTG) that was placed below a coronally advanced envelope flap and acted as a buccal soft tissue wall of the bony defect treated with enamel matrix derivative (EMD).

Clinical and histopathologic independent prognostic factors in oral squamous cell carcinoma: a retrospective study of 334 cases.

Purpose: This retrospective hospital-based study reviewed and evaluated the outcome of patients with oral squamous cell carcinoma (OSCC) with the aim of identifying factors affecting the clinical course and survival rate.

Patients And Methods: Patients with a follow-up of at least 12 months were included. The data collected were statistically analyzed for the presence of factors valuable for prognosis; survival curves were processed in accordance with the Kaplan-Meier method.

Oral pemphigoid autoantibodies preferentially target BP180 ectodomain.

Mucous membrane pemphigoid (MMP) comprises a heterogenous group of autoimmune subepithelial bullous diseases very frequently having oral involvement. Very few studies have investigated the immunological status of a subset of MMP, termed oral pemphigoid (OP), presenting with exclusive oral lesions. In this study we show that 75% of 20 OP patients without scarring phenotype possessed circulating autoantibodies against the BP180 molecule, indicating a prominent role of this protein as a target antigen in OP.
