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)
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 purpose of the present study was to compare the clinical and radiographic outcomes of single implants immediately placed and restored with two different implant-abutment connections. MATERIALS AND METHODS Forty subjects requiring single maxillary premolar replacement were consecutively included in this study and prospectively followed for 12(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 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)
PURPOSE To evaluate whether 7-mm-long implants could be a suitable alternative to longer implants placed in vertically augmented bone for the treatment of atrophic posterior mandibles. MATERIALS AND METHODS Sixty partially edentulous patients having 7 to 8 mm of residual crestal height and at least 5.5 mm thickness measured on a computed tomography scan(More)
AIM We present a newly designed, localiser-free, head-mounted system featuring augmented reality as an aid to maxillofacial bone surgery, and assess the potential utility of the device by conducting a feasibility study and validation. METHODS Our head-mounted wearable system facilitating augmented surgery was developed as a stand-alone, video-based,(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)
AIM To evaluate prospectively the clinical and radiographic outcomes after 2 years of loading of 6 mm long moderately rough implants supporting single crowns in the posterior regions. MATERIAL AND METHODS Forty SLActive Straumann short (6 mm) implants were placed in 35 consecutively treated patients. Nineteen implants, 4.1 mm in diameter, and 21 implants,(More)
