Twenty-eight osteosarcomas (OS) of the jaw were reported. There were 15 male and 13 female patients (age range, 9 to 68 years; mean, 36.9 years); 57.1% of the patients were older than 30 years of age. Swelling was the most frequent symptom; it was reported on an average of 6 months before diagnosis. Most of the tumors of the maxilla (eight patients)(More)
The frequent spread of oral squamous cell carcinoma (OSCC) has been explained by the persistence of genetically altered mucosa after surgery. This study examined whether clinically and histologically 'normal' mucosa distant from the primary tumour (from the opposite cheek) has an abnormal proliferative status, and whether this is associated with poor(More)
BACKGROUND The present study evaluated the efficacy of a treatment consisting of placing and immediately loading implants with a bar-retained overdenture in edentulous maxillae. METHODS Twenty-two consecutive patients were treated with four or five implants rigidly connected with a bar, which were then loaded with a maxillary overdenture within 48 hours(More)
Metastases to cervical lymph nodes (LNs) are an important independent adverse indicator in the prognosis of oral squamous cell carcinoma (OSCC). An accurate evaluation of molecular patterns favoring the metastatic process can be helpful in predicting cases of OSCC with elevated probability of early or late metastases and, moreover, in planning the proper(More)
OBJECTIVE The 'retromolar' nerve is a collateral branch of the inferior alveolar nerve. Cone-beam computed tomography (CBCT) provides higher resolution images. This CBCT study reports the frequency of the retromolar nerve. MATERIALS AND METHODS From 2007-2010 the CBCT study of 233 hemi-mandibles have been examined. The CBCT study was obtained from an(More)
Computer-based surgery simulation is a rapidly emerging and increasingly important area of research that combines a number of disciplines for the common purpose of improving healthcare. The objective of this paper is to provide a virtual surgery (VISU) tool for accurately planning the aesthetic impact of hard and soft tissue movements in dento-skeletal(More)
OBJECTIVES To compare two different techniques for vertical bone augmentation of the posterior mandible: bone blocs from the iliac crest vs. anorganic bovine bone blocs used as inlays. MATERIALS AND METHODS Ten partially edentulous patients having 5-7 mm of residual crestal height above the mandibular canal had their posterior mandibles randomly allocated(More)
The purpose of this study was to evaluate treatment of resorbed posterior mandibles with interpositional bone grafts (the "sandwich" technique) and implant-supported prostheses. Six consecutive patients with resorbed posterior mandibles (seven sites) were 4reated by the sandwich osteotomy technique with an interpositional bone graft harvested from the iliac(More)
OBJECTIVE The objective of this study was to compare bone gain, implant survival, implant success, bone resorption, and complication rate in groups of patients who underwent distraction osteogenesis (DO) and inlay bone grafting (Inlay) for preprosthetic issues in the atrophic posterior mandible. STUDY DESIGN Twelve surgical sites were randomly assigned to(More)
PURPOSE The objectives of this study were to (1) evaluate the survival of implants placed in maxillary sinuses augmented with a 70:30 mixture of autogenous bone and anorganic bovine hydroxyapatite (Bio-Oss) at 1 and 5 years, (2) observe the difference in survival rate between 1-stage and 2-stage procedures, and (3) compare the survival rate of(More)
