Omophroninae is a distinctive monogeneric group of Carabidae, presumably placed relatively close to the root megadiverse adephagan family. In present study we describe larva belonging from mid-Cretaceous Burmese amber and erect new genus † Cretomophron . Several features support placement in this small but subfamily, such as wedge-shaped head, large triangular nasale, elevated antennae with api...

Severe vertical ridge deficiency in the anterior maxilla represents one of the most challenging clinical scenarios in the bone regeneration arena. As such, a combination of vertical bone augmentation using various biomaterials and soft tissue manipulation is needed to obtain successful outcomes. The present case series describes a novel approach to overcome vertical deficiencies in the anterior...

Odontogenic myxomas (OMs) are benign mesenchymal locally aggressive neoplasms of the jaw bone. Although OMs predominantly involve the mandible, maxillary tumors are usually more aggressive than mandibular tumors. The present study describes the case of a 37-year-old male with a large odontogenic myxoma of the bilateral maxillae, which caused a defect in the right skull base bone. The tumor was ...

The aim of this study was to investigate the possible use and ultimate fate of anorganic xenogenic bone for the restoration of defects in the maxillae and mandibles of adult rabbits. Furthermore, anorganic xenogenic bone was compared with implanted autogenous bone particles with regard to the response of the surrounding connective tissue and possible resorption of these implants by multinucleat...

A surgical procedure for the rehabilitation of severely resorbed maxillae is described. Twenty-five patients, made up of a development group of 5 and a routine group of 20, were treated with Le Fort I osteotomy using interpositional bone grafts from the iliac crest and, in a second stage, titanium implants. Altogether, 181 Brånemark implants were placed, and the patients were followed for up to...

The objective of this study is to analyze the biomechanical effects of sinuses in the skull on the facial impact response. Two models were built, where one had sinuses and the other had none. The models were verified using cadaver test data, including impacts to frontal bone, zygomatic bone, and maxillae. In the maxilla and zygoma impact, sinuses were found to have no significant effect on the ...
