The objective of this study was to investigate the adhesion, spreading and extracellular matrix synthesis of temporomandibular joint (TMJ) derived cells on non-absorbable scaffold materials to ultimately provide a durable stress-absorbent framework within tissue-engineered disc transplants. Scaffolds were prepared by polyamide monofilaments, expanded(More)
In this study, we investigated the growth and extracellular matrix synthesis of human osteoblast-like cells on highly porous natural bone mineral. Human bone cells were isolated from trabecular bone during routine iliac crest biopsies. Under conventional culture conditions, trabecular bone cells were able to assume the organization of a three-dimensional(More)
It was the aim of the present study to investigate the induction of dentin formation by recombinant human osteogenic protein-1 (hOP-1). In 4 adult miniature pigs a total of 16 teeth with artificially exposed dental pulps were capped with 3 mg of a complex of recombinant hOP-1 in collagen matrix (2.5 micrograms/mg), collagen matrix alone, or calcium(More)
We investigated the possibilities of sonographic diagnostics of bone fractures in a clinical study. 18 patients with fractures of the lower jaw were examined. The technical procedure and typical symptoms are described. The sonographic analysis shows fractures with dislocations greater than 1 mm. Today it is not possible yet to exclude a fracture by(More)
The effect of occlusal support during primary dentition on the mandibular condyle remains controversial. We sought to determine whether unilateral loss of occlusal support leads to quantifiable adaptive changes of the condyle. Quantitative analysis of condylar growth and spongy bone volume after unilateral removal of teeth on the left side in adolescent(More)
39 condylar mandibular fractures were examined by magnetic resonance imaging (MRI) within the first 12 hours after trauma prior to therapy. A new classification has been applied on the traumatic disc displacements. Three types A, B, C can be distinguished. Type A means no displacement in relation to the condylar fragment and the fossa. Type B means a(More)
There is a difference in the vascular architecture of myocutaneous flaps and jejunal free flaps both available to replace resected mucosal tissue of the oral cavity after surgical treatment of oral cancer. The question in whether the mobilization of jejunal free flaps is possible without respect to the anastomized vessels in particular in secondary(More)
