accurate prediction of the surgical outcome is important in treating dentofacial deformities. visualized treatment objectives usually involve manual surgical simulation based on tracing of cephalometric radiographs. recent technical advancements have led to the use of computer assisted imaging systems in treatment planning for orthognathic surgical cases. the purpose of this study was to examin...

BACKGROUND Dolphin® visual treatment objective (VTO) prediction software is routinely utilized by orthodontists during the treatment planning of orthognathic cases to help predict post-surgical soft tissue changes. Although surgical soft tissue prediction is considered to be a vital tool, its accuracy is not well understood in tow-jaw surgical procedures. The objective of this study was to quan...

The purpose of this retrospective study was to evaluate the treatment effects of the variable anchorage straightwire technique (VAST) in Angle Class II patients using Ricketts' growth prediction analysis. The subjects belonged to two groups: a control, consisting of 30 untreated Class II Swedish individuals (20 girls, 10 boys) with a mean age of 11.2 years, and the other 29 Swedish patients (14...

Using fMRI, we showed that an area in the ventral temporo-occipital cortex (area vTO), which is part of the human homolog of the ventral stream of visual processing, exhibited priming for both identical and depth-rotated images of objects. This pattern of activation in area vTO corresponded to performance in a behavioral matching task. An area in the caudal part of the intraparietal sulcus (are...

BACKGROUND A hierarchical taxonomy of organisms is a prerequisite for semantic integration of biodiversity data. Ideally, there would be a single, expansive, authoritative taxonomy that includes extinct and extant taxa, information on synonyms and common names, and monophyletic supraspecific taxa that reflect our current understanding of phylogenetic relationships. DESCRIPTION As a step towar...

This paper presents the conceptual CAD system VCAD that supports construction of Virtual Technical Objects (VTO) in a three-dimensional stereoscopic environment using pre-defined virtual construction elements. From the newly created VTO, the CAD system automatically produces the drafts needed for the production of the real technical object. This approach contrasts considerably from the traditio...

Aim The aim of this study was to assess the accuracy Dolphin VTO prediction in patients requiring extraction treatment by comparing VTO-predicted values and post-treatment values. Method Digital pre lateral cephalograms 52 having Class I bimaxillary protrusion were taken transferred Imaging software for analysis prediction. A composite made containing 17 dental soft tissue parameters (Holdaway,...

We studied the K(+)-selective conductances in primary cultures of rat renal inner medullary collecting duct (IMCD) using perforated-patch and conventional whole cell techniques. Depolarizations above -20 mV induced a time-dependent outward K(+) current (I(vto)) similar to a delayed rectifier. I(vto) showed a half-maximal activation around 5.6 mV with a slope factor of 6.8 mV. Its K(+)/Na(+) sel...
