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)
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)
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)

Obstructive sleep apnoea syndrome is the periodic reduction or cessation of airflow during sleep together with daytime sleepiness. Its diagnosis requires polysomnographic evidence of 5 or more episodes of apnoea or hypopnoea/hour of sleep (apnoea/hypopnoea index, AHI). Volumetric 3-dimensional computed tomographic (CT) reconstruction enables the accurate(More)
BACKGROUND Juvenile paradental cysts typically occur on the buccal aspect of mandibular first and second molars in children aged 6 to 11 years. The cysts may be treated by enucleation, with or without extraction of the involved teeth, or by marsupialization. This report demonstrates the success of a conservative surgical technique (marsupialization) and(More)
Because of the recent development of three-dimensional technology, computer software is increasingly being used for diagnosis, analysis, data documentation, and surgical planning for orthognathic surgery. Currently, the typical method to reposition jaws in the correct and planned location is based on the use of surgical splints, which have a quite high(More)
Qualitative/quantitative phytochemical variations were observed in dried flowering tops of cultivated Hypericum perforatum L. cv. Zorzi infected by phytoplasmas of the "ash yellows" class, identified by direct and nested polymerase chain reaction (PCR); this is the first report of ribosomial group 16SrVII phytoplasmas in St. John's Wort. Methanolic extracts(More)
PURPOSE Facial soft tissue prediction in orthognathic surgery could be a valuable aid to preview the results and determine the best surgical treatment. After many years, considerable difficulties are still present in the prediction of the clinical final aspect. The object of the present study was to validate new soft tissue simulation software (SurgiCase(More)
BACKGROUND The aim of oromandibular reconstruction following a partially or fully extended resection is to recreate the normal morphology with a mandibular profile as similar as possible to the original and to restore oral function. Oromandibular reconstruction can be performed with fibula osteocutaneous free flaps combined with the preplating technique.(More)
