BACKGROUND/AIMS It was the aim of this study to carry out a comparative evaluation in vitro on standardized color charts and in vivo on healthy subjects using the Visi-Chroma VC-100, a new imaging tristimulus colorimeter and the Minolta Chromameter CR-200 as a reference instrument. The Visi-Chroma combines tristimulus color analysis with full color(More)
Conventional devices used for surgically assisted rapid palatal expansion are tooth-borne. Dental fixation entails a number of possible drawbacks such as loss of anchorage, skeletal relapse during and after the expansion period, cortical fenestration and buccal root resorption. A bone-borne titanium device with interchangeable expansion modules, used with a(More)
PURPOSE Frequency and severity of complications have a profound impact on referral patterns for facial orthopedic surgery. Therefore, a retrospective study was undertaken to determine the incidence of such problems in a large series of patients, with the intent to use these data to make possible changes in the perioperative protocol used in our clinic.

Cone-beam computed tomography (CBCT) is used for maxillofacial imaging. 3D virtual planning of orthognathic and facial orthomorphic surgery requires detailed visualisation of the interocclusal relationship. This study aimed to introduce and evaluate the use of a double CBCT scan procedure with a modified wax bite wafer to augment the 3D virtual skull model(More)
Clinical photography is an essential facility to support the work of cranio-maxillo-facial surgical departments. This paper highlights the requirements to ensure the highest quality and consistency of photographs taken and provides a standardized set of both facial and intra-oral views that fit the needs of accurate digital photo-documentation in(More)
BACKGROUND Non-syndromic Tessier no. 2 and 3 facial clefts primarily affect the nasal complex. The anatomy of such clefts is such that the ala of the nose has a cleft. Repairing the ala presents some challenges to the surgeon, especially to correct the shape and missing tissue. Various techniques have been considered to repair these cleft defects. AIM We(More)
A retrospective study was performed to examine the occurrence of condylar atrophy in connection with orthognathic surgery. Patients with high-angle mandibular deficiency (n = 29) were selected from among those who underwent bimaxillary osteotomy (n = 93) during the period from January 1987 through December 1990. This group of 29 was examined for shortening(More)
A detailed visualization of the interocclusal relationship is essential in a three-dimensional virtual planning setup for orthognathic and facial orthomorphic surgery. The purpose of this study was to introduce and evaluate the use of a wax bite wafer in combination with a double computed tomography (CT) scan procedure to augment the three-dimensional(More)
AIM To assess the three dimensional (3D) surface accuracy of a phantom's face acquired from a cone-beam computed tomography (CBCT) scan and to determine the reliability of selected cephalometric measurements performed with Maxilim software (Medicim N.V., Mechelen, Belgium). MATERIAL AND METHODS A mannequin head was imaged with a CBCT (I-CAT, Imaging(More)
