A three-dimensional soft tissue study of the results of surgery in a group of 15 women with Class II, Division I malocclusions after orthognathic surgery was performed with laser scans. A group of 30 women with Class I malocclusions ages between 19 and 25 years were used as controls. Laser scans were taken before surgery, 3 months after surgery, and at(More)
OBJECTIVES The primary objective of this study was to assess the inter-day reproducibility of cutaneous thermal hyperaemia, as assessed using integrating-probe laser Doppler flowmetry (LDF), in young and older men. A secondary objective was to identify the most reproducible form of data expression. METHODS Cutaneous thermal hyperaemia was assessed on the(More)
Optical surface scanning technologies produce dense three-dimensional (3D) data sets, which allow detailed analysis of surface morphology. This paper describes a method of analysing change in facial shape independently of change in size. The 3D data from three male subjects from the age of 6-21 years were recorded using an optical surface scanner. A series(More)
The ability to increase skin blood flow (SkBF) rapidly in response to local heating is diminished with advanced age; however, the mechanisms are unclear. The primary aim of this study was to investigate the role of sensory nerves in this age-related change. A secondary aim was to investigate the effect of aerobic fitness on sensory nerve-mediated(More)
The purpose of this prospective study was to help distinguish the relative contributions of heredity and environment to the external facial features and to assess the relative strength of the genetic influence on anteroposterior and vertical facial parameters, by using 3-dimensional optical surface scanning and the inferential twin method. The subject group(More)
One of the problems of patients with facial asymmetry is that two dimensional analysis of such patients does not give a satisfactory picture of the underlying problem. Various methods have been suggested to overcome this problem, such as stereophotogrammetry (Burke et al. 1983) and Moire fringes (Takasaki 1970, Xenofos and Jones 1979). These methods are(More)
A system has been developed for the three-dimensional (3D) visualization of the face and skull using data obtained from a purpose-built no-contact laser scanning system and from a series of scans produced by X-ray computerized tomography. Features developed allow the simulation, planning and prediction of maxillo-facial surgery. Realistic skeletal and(More)
A computer system has been developed for the simulation of facial surgery with interactive three-dimensional graphic techniques and data derived from computed tomographic scans and a purpose-built laser scanning system. The simulation includes the surgery on the hard tissues, and modeling of the soft tissue for prediction of the postoperative facial(More)
The possibility of using computer-aided design as a tool for the planning and simulation of facial reconstruction surgery is discussed and has been shown to be feasible. Methods of acquiring the essential measurements on the facial surface and the underlying bone structure in a computer-compatible form are described, including a new approach which has been(More)
