PURPOSE The aim was to evaluate the outcome of a short wide-body implant in the atrophic posterior jaw without a grafting procedure. MATERIALS AND METHODS Patients treated with a tapered wide-body implant measuring 8 to 9 mm in width and 7 to 9 mm in length (Max implant; Southern Implants, Irene, South Africa) were recalled to scrutinize implant survival.(More)
Autologous buccal mucosa as a substitute for urethral epithelium was studied in 2 dogs and used in 6 patients with difficult urethral reconstruction problems. The indications for an operation in these patients were failed hypospadias repairs with limited skin in 3, severe structure disease after hypospadias repair in 1, a short urethra in 1 and epispadias(More)
Recent studies have identified a subpopulation of craniosynostotic individuals who exhibit progressive or delayed-onset synostosis and mild craniofacial growth abnormalities. These individuals may be good candidates for nonextirpation, distraction osteogenesis therapy. The present study was designed to test this hypothesis by using internal calvarial bone(More)
Recent studies have identified a subpopulation of persons with craniosynostosis who exhibit progressive or delayed-onset synostosis and mild cranial vault deformities. These persons may be good candidates for nonextirpation distraction osteogenesis. The present studies were designed to determine force-displacement parameters and assess the effects of(More)
This study was designed to assess the effects of overdistraction of an experimentally immobilized coronal suture using an internal appliance on craniofacial growth in rabbits. Fifty-three, 1.5-week-old rabbits were used. Markers were placed on either side of the calvarial sutures. Thirty-nine rabbits had bilateral coronal suture immobilization using methyl(More)
Experience with the use of cytotoxic drugs in the first trimester of pregnancy is limited. We report on the clinical phenotype and infantile development of a girl born to a 36-year-old mother. Before recognition of pregnancy, the latter had been treated for acute myelocytic leukaemia receiving cytarabine, daunorubicin and doxorubicin at conception and(More)
The preoperative manufacturing of individual skull implants, developed by an interdisciplinary research group at Ruhr-University Bochum, is based on the use of titanium as the most common material for implants at present. Using the existing technology for materials that can be milled or moulded, customized implants may be manufactured as well. The goal of(More)
A series of studies were designed to assess the potential of biodegradable DL-polylactic acid (DL-PLA) plates and screws for use in craniofacial surgery. We report on computed tomography (CT) scanning for visualization and postoperative follow-up and the short-term degradation sequelae of a biodegradable plate and screw system in an experimental animal(More)
A recently developed biodegradable system made of DL-polylactic acid (DL-PLA) for internal fixation of non-weight-bearing bones of the craniofacial skeleton was investigated. The plates were used for rigid fixation of experimental nasal bone fractures in 20 New Zealand white rabbits. In addition, prebent plates were placed in subcutaneous pockets in the(More)
Experimental rabbit models of postnatal coronal suture (CS) synostosis have helped make significant contributions towards the understanding and surgical management of human congenital craniosynostosis. The present study compares craniofacial growth patterns in animals with experimental CS immobilization and in a rabbit born in our laboratory with congenital(More)
