OBJECTIVES The aim of this study was to evaluate the effects of scanning parameters on the precision of the data acquired using a facial laser scanner and to assess the reliability of automatic model recording in humans. METHODS Data were acquired using a laser scanner (Cyberware 3030RGB); analysis and measurements were performed with Rapid Form 2004(More)
Immunohistochemical analysis of the extrahypothalamic distribution of vasotocin-like immunoreactive elements within the central nervous system of the domestic fowl and Japanese quail, revealed several mesencephalic, pontine and bulbar target areas topographically identifiable. Extrahypothalamic immunopositive perikarya were observed in diencephalic and(More)
This longitudinal study investigated the 3-D facial soft-tissue response to transverse palatal bone-anchored osteodistraction in 18 adult patients. Laser-scanned facial surface data were obtained for all patients before (T(0)), 6 months (T(1)) and 1 year (T(2)) after transverse palatal distraction. The averaged facial morphologies at T(0), T(1) and T(2)(More)
In this immunocytochemical study we investigated the distribution of nervous structures in the lower lip of adult rats. The region is characterized by a rich cutaneous and mucosal sensory innervation originating from terminal branches of the trigeminal system. Lower lip innervation was investigated by detection of the general neuronal marker protein gene(More)
Neuronal morphology and dendritic architecture of the tuberal and mammillary regions in the hypothalamus of the quail (Coturnix coturnix japonica) were investigated by means of classical neuroanatomical methods (Bodian silver impregnation, Luxol-fast blue, cresyl violet, toluidine blue, rapid Golgi method). The tuberal region is characterized by(More)
Quantifying soft tissue changes after orthognathic surgery is increasingly important in surgical planning, but little is actually known about the changes in facial mobility after surgery. In the current study, we investigated facial mimics in patients before and after orthognathic surgery. Eleven patients with jaw discrepancy requiring maxillary and/or(More)
An immunohistochemical investigation for the neurospecific markers S-100 protein and protein gene product 9.5 was carried out on 12 healthy temporomandibular joint discs and capsules that were taken at autopsy from human adults. Large nerve trunks in the joint capsule and posterior disc ligament, as well as small nerve bundles and single nerves in almost(More)
Unilateral posterior crossbite is a widespread, asymmetric malocclusion characterized by an inverse relationship of the upper and lower buccal dental cusps, in the molar and premolar regions, on one side only of the dental arch. Patients with unilateral posterior crossbite exhibit an altered chewing cycles and the crossbite side masseter results to be less(More)
The objective of this study was to assess the accuracy of displacements of tracing landmarks in standardized facial movements. Forty healthy persons were evaluated in 2 different groups (20 men and 20 women, aged 18-30 years) with optoelectronic motion analyzer and surface laser scanning. The displacements of tracing landmarks in brow lift and smile were(More)
