The survival of loaded implants is critically dependent on their biomechanical stability. We have used a computer-guided navigation technique to evaluate the accuracy of computer-assisted insertion for immediately-loaded implants in minipigs. On the basis of computed tomographical data, the Robodent system was used for preoperative planning and guidance of(More)
PURPOSE The conventional impression technique for manufacturing facial prostheses has the disadvantage of deforming the soft tissues because of the tension caused by the impression material, as well as causing discomfort to the patient. The purpose of this study was to establish a system that allows contact-free reproduction of the facial surface combined(More)
INTRODUCTION Symmetry has been found to play a crucial role in attractiveness assessment and so its restoration is an essential problem in oral maxillofacial surgery. This paper presents an overview of recent 2D asymmetry analysis techniques. These are techniques which are based on the evaluation of two-dimensional data, like photos. The aim of this paper(More)
INTRODUCTION Oral implants placed in the maxilla, especially the posterior region, have a lower success rate than those placed in the mandible. Poor bone quantity and quality have been suggested as a reason for this differential success rate. OBJECTIVE The purpose of this study was, therefore, to evaluate stress and strain distributions around loaded(More)
Regarding the cosmetic results of wound closure using tissue adhesives as opposed to sutured wounds, most published studies are performed on children and with non-standardized lacerations, which makes it difficult to transfer the results to facial incisional wounds in adults. There are also conflicting conclusions about the cosmetic results. The purpose of(More)
AIM OF THE STUDY Cosmetic outcome of surgical treatment in the facial region is influenced by the appearance of the scar. The purpose of this investigation was to evaluate the objectivity and validity of various methods for the assessment of scars. MATERIAL AND METHODS 45 patients undergoing facial surgery were examined three months after surgery. Three(More)
Symmetry is a significant factor, among others, influencing the attractiveness of human faces. Hence its restoration is an essential task in oral and maxillofacial surgery. Until recently, most of the techniques to objectively quantify the facial asymmetry were based on the evaluation of two-dimensional data, i.e. photographs. These techniques are(More)
STATEMENT OF THE PROBLEM Alterations to the oral cavity caused by dental prostheses can affect speech articulation, whereas the influence of dental prostheses on the voice is unknown. For 1 patient, the fundamental frequency rose by up to 5 semitones during speech and his voice range was enlarged by up to 4 semitones when a thin denture was used instead of(More)
A method for the acquisition and evaluation of 3D coordinates from anatomically oriented plaster casts is presented, which is based on optical phase shifting profilometry (a fringe projection technique). With the computer-controlled setup, measurements from different views can be combined to obtain a complete three dimensional reconstruction of the model(More)
