The aim of this study was to compare two different types of surgical approaches, intrasinus and extramaxillary, for the placement of zygomatic implants to treat atrophic maxillae. A computational finite element simulation was used to analyze the strength of implant anchorage for both approaches in various occlusal loading locations. Three-dimensional models of the craniofacial structures surrou...

The aim of this work was to present a novel minimally invasive surgical stabilization technique for canine atlanto-occipital dislocation and to report the associated magnetic resonance imaging (MRI) findings. All 5 dogs in this case series underwent 1.5 T MRI of the head and neck and 3 underwent both MRI and computed tomography (CT). Atlanto-occipital dislocations were diagnosed based on the in...

Authors report their experience in the treatment of midfacial fractures in 201 patients, 177 of whom underwent surgery for reduction and fixation of the fracture. Since no functional or aesthetic deficits were present, surgery was not performed in the remaining 24 cases. Of the 177 patients, the maxillary complex was involved in 70 (classified as central and centro-lateral fractures), the zygom...

The geographic variation in skull size and shape of the swamp rat Scapteromys tumidus was examined in samples from eight geographic clusters in almost of its distribution in southern Brazil and Uruguay. For analysis we used two-dimensional geometric morphometric methods for dorsal, ventral and lateral views of the skull. The geometric descriptors showed no significant differences in skull size ...

Hypotheses regarding patterns of stress, strain and deformation in the craniofacial skeleton are central to adaptive explanations for the evolution of primate craniofacial form. The complexity of craniofacial skeletal morphology makes it difficult to evaluate these hypotheses with in vivo bone strain data. In this paper, new in vivo bone strain data from the intraorbital surfaces of the supraor...

Although a rarely encountered clinical entity, hyperplasia of the coronoid process is a condition that dental practitioners should consider when encountering patients with limited mandibular movements. The condition was first described by von Langenbeck in 1853, though currently the actual incidence is unknown. Coronoid hyperplasia may occur bilaterally or unilaterally, and is defined as an inc...

A previous Overview described suitable sites for vestibular miniscrew insertion.1 Although these locations are commonly used in orthodontic applications because of their ease of access, the interradicular spaces are limited by the proximity of neighboring roots (Fig. 1), presenting the following problems: • Risk of damaging the roots or the periodontium. • Possibility of miniscrew-root contact ...
