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)
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)
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)
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)
PURPOSE The aim of the study was to measure the influence of the maxillary central incisors free from adaptation phenomena using spectral analysis. MATERIALS AND METHODS The maxillary dentures of 18 subjects were duplicated. The central incisors were fixed in a pivoting appliance so that their position could be changed from labial to palatal direction. A(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)
STATEMENT OF PROBLEM The insertion of prosthodontic restorations often leads to speech defects, most of which are transient but nevertheless a source of concern to the patient. For the dental practitioner, there are few guidelines on designing a prosthetic restoration with maximum phonetic success. PURPOSE This study investigated the effect of different(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)
Many factors are thought to be responsible for misarticulation. Maxillomandibular or dental irregularities play an important role as one of these factors. Correlations between morphological changes in dental status and speech disorders are well known, but different opinions are discussed in the literature. A reciprocal relationship between dysfunction and(More)
