Microdamage reduces bone mechanical properties and thus could possibly contribute to implant failure. The objective of this study was to investigate whether the diameter of mini-implants (MI) affects microdamage generation and whether this differs between the mandible and maxilla due to their contrasting cortical thicknesses. Methods: Maxillary and mandibular quadrants of 5 dogs were randomly a...

OBJECTIVES The purpose of this study was to prospectively evaluate the clinical and radiographic outcomes of immediately loaded full-arch fixed prostheses supported by a combination of axially and non-axially positioned implants in a large cohort of patients with completely edentulous jaws, up to 5 years of function. MATERIALS AND METHODS One hundred and seventy-three edentulous patients (80 ...

PURPOSE Loss of alveolar bone in the anterior maxilla may preclude implant placement or compromise positioning and thus diminish the final esthetic result of the restoration. Bone augmentation can overcome such difficulties but may affect osseointegration. The aim of this study was to report the outcome of buccal onlay bone grafting in the anterior maxilla in routine dental implant practice. ...

BACKGROUND Bone density at the interradicular area plays an important role during orthodontic treatment. In view of this fact, the study was designed to quantitatively evaluate the bone density at the interradicular areas of the alveolar and basal bones of maxilla and mandible by computed tomography. METHODS One hundred and nine computed tomographic images were randomly selected, and bone den...

Objective: to investigate the predictive factors of failure in bone grafts for alveolar ridge augmentation and implant surgery. Methods: we reviewed the charts of 166 patients operated between 1995 and 2014. A total of 248 grafting procedures were performed. We submitted the data to the binomial test at 5% significance. Results: grafts to gain width of the alveolar ridge (65.32%) were more freq...

The prosthetic rehabilitation of patients with an edentulous maxilla opposing mandibular anterior natural teeth is one of the most challenging situations that a clinician encounters. Occlusal forces from the opposing natural teeth may cause fractures in the maxillary prosthesis and also result in residual ridge resorption of the edentulous maxilla. Prosthodontists try overcoming this Combinatio...

Purpose: Highly crystalline thin hydroxyapatite (HA) layers deposited on the surface of commercially pure titanium (cpTi) by discharge anodic oxidation and hydrothermal treatment (SA treatment) enhance the value of cpTi as endosseous implants in clinical dentistry. In particular, the SA treatment affects the osteoconductive properties of cpTi. Determining whether this HA layer retains its chemi...

OBJECTIVES The study was aimed to evaluate the pharyngeal airway linear measurements of untreated skeletal class II subjects with normal facial vertical pattern in prognathic maxilla with orthognathic mandible and orthognathic maxilla with retrognathic mandible. MATERIALS AND METHOD the sample comprised of lateral Cephalograms of two groups (30 each) of class II malocclusion variants. Group 1...

A 43-year-old woman with a unilateral cleft lip and palate, presenting a totally edentulous maxilla and mandible with marked maxillomandibular discrepancy, attended the Prosthodontics section of the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo for treatment. She could not close her mouth and was dissatisfied with her complete dentures. Treatment planning compri...

PURPOSE The aim of this study was to investigate dental arch dimensions and to classify arch shape in Korean young adults. MATERIALS AND METHODS The sample included 50 Koreans with age ranging from 24 to 32 years. Maxillary and mandibular casts were fabricated using irreversible hydrocolloid and type III dental stones. Incisor-canine distance, incisor-1st molar distance, incisor-2nd molar dis...
