Background: Guidelines for antibiotics prior to dental procedures for patients with specific cardiac conditions and prosthetic joints have changed, reducing indications for antibiotic prophylaxis. In addition to guidelines focused on patient comorbidities, systematic reviews specific to dental extractions and implants support preprocedure antibiotics for all patients. However, data on dentist adherence to these recommendations are scarce. Methods: This was a cross-sectional study of veterans undergoing tooth extractions, dental implants, and periodontal procedures...

For the regeneration of small osseous defects, dental membranes are commonly used in oral and maxillofacial surgery. A new synthetic resorbable membrane has recently demonstrated its biocompatibility and bone regeneration capacity in preclinical studies. This membrane is made of poly-D,L-lactic/glycolic acid 85/15 (PLGA), has a bi-layered structure with a dense film to prevent gingival epithelial cell invasion and a micro-fibrous layer to support osteogenic cells and bone healing. This membrane completely degrades by hydrolysis in 4 to 6 months without signs of inflammation...

The implant-prosthetic rehabilitation of edentulous upper jaws has always been complex for surgeons and dentists. The lack of bone in both vertical and horizontal dimension does not allow the correct insertion of dental implants. In addition, patients with edentulous upper and lower arch have a loss of vertical dimension of the face and an aged expression. Many surgical techniques have been proposed to increase the bone volume, height and thickness, such as the Le Fort I osteotomy, the bone grafts and the placement of dental implants...

Spiral dental implant (SDI) is an implant with a conical internal helix that confers the characteristic of self-drilling, self-tapping, and self-bone condensing. These proprieties offer better control during insertion of SDI giving a high primary stabilization, even in poor quality bone. A shorter diameter of SDI results in reduced drilling during insertion and consequently less trauma and minimal bone loss. To address the research purpose, the investigators designed a retrospective cohort study. The study population was composed of 25 patients, 11 males and 14 females that have been treated by Dr...

Diagnostic imaging acts as a distinctive method in analyzing and drawing in the appropriate treatment protocol for any procedure. Pertaining to immediate implant placement, determining the bone width and height plays a vital role in the success of the implant therapy. This visualization of the measurements done preoperatively will enhance the treatment by reducing the overall time span of the procedure. Currently, cone beam computed tomography (CBCT) plays a significant role in the preoperative determination of the measurements of the tooth and the bone...

BACKGROUND: Fixed prosthodontic treatment (crowns, fixed dental prostheses (FDPs), complete arch prostheses) involves the use of several different materials to replace missing tooth structure. Traditionally full metal or metal frameworks veneered with ceramic (metal-ceramic (MC)) have been used. In recent years several different metal-free systems have become available to clinicians and patients. In general, metal-free restorations should allow practitioners to better reproduce natural tooth colour, avoiding shortcomings of MC restorations...

Given the popularity of dental implants, determining their prognosis is an integral component of dental practice. An accurate prognosis is crucial to development of an appropriate treatment plan and may require alterations as overall status or the status of implants or natural teeth change. The importance of an established set of factors for determining implant prognosis would be highlighted in dentist-patient communication and in interdisciplinary collaboration. The main objective of the proposed prognostication system is short- and long-term success of dental implants...

INTRODUCTION: Osteosarcoma is an aggressive primary bone tumor composed of connective tissue cells directly producing osteoid and bone. Prosthetic rehabilitations in post-oncological patients after bone reconstruction are not substantially different than those of patients affected by severe atrophy of upper or lower jaw after bone reconstruction. The treatment for patients with a malignant neoplasia of the oral cavity requires multidisciplinary approach by a team of different specialists that follow the patient through the phases of diagnosis, therapy and oral rehabilitation...
