PURPOSE To evaluate the soft tissue changes after correction of Class III dentoskeletal deformity with orthognathic surgery using the optical surface scanner as a 3-dimensional imaging tool and thin-plate splines as a morphometric analysis. PATIENTS AND METHODS Forty-six patients with Class III dentoskeletal relationship who underwent a bimaxillary(More)
Pressure therapy using custom-made pressure clips or splints is widely used for the treatment of ear keloid scars; however, it is often difficult to control the amount and direction of pressure applied. One of the most common complications of this therapy is ulceration due to excessive soft tissue pressure, resulting in delays and prolonged treatment time.(More)
PURPOSE This study investigated the differences in centric occlusion (intercuspal-CO) and centric relation contact position (CR) in patients in an upright and supine posture when conscious and when supine under general anesthesia to rationalize planning for complex bimaxillary osteotomies. PATIENTS AND METHODS Twenty-four men and 37 women, with a mean age(More)
A novel device for a bite force measurement system in a porcine model is described. A single polyethylene layer was vacuum-formed into a splint, and a force sensor was fitted on to the splint occlusal surface and seated with a silicone layer. This design enabled the measurement of bite forces on selected teeth in a large animal model with either natural(More)
The aim of this study was to compare two types of osteotomy wafers, derived from model surgery on a semi-adjustable anatomical articulator. The thick wafer was fabricated before autorotation of the mandibular cast and the thin after the autorotation. Twenty-five patients, 19 female and 6 male, who had osteotomies with a maxillary impaction as part of a(More)
The aim of this study was to compare cephalographs and optical surface scanner images (lasergraphs) by measuring the lipincisor relationship, the nasolabial angle, nasal tip projection, the nasofacial angle, the nasomental angle, and the labiomental angle in pre- and postoperative orthognathic surgery patients. The results showed that the methods were(More)
In order to create an evidence-based orthognathic surgery planning protocol, an investigation of two popular model surgery techniques, the Lockwood keyspacer and the Eastman anatomically-orientated system was carried. This determined (a) the accuracy of positioning of the maxillary cast according to the prescribed treatment plan and (b) the relocation of(More)
The relative reproducibility of two widely used arbitrary face-bow transfer systems, the Denar Slidematic and the Dentatus type AEB, was assessed for use in orthognathic surgery planning. A novel method was also developed to determine any variation in three-dimensional spatial position and orientation of the maxillary cast. This envelope of movement enabled(More)
PURPOSE The aims of the study were to assess the degree of accuracy of model surgery performed manually using the Eastman technique and to compare it with model surgery performed with the aid of a robot arm. PATIENTS AND METHODS Twenty-one patients undergoing orthognathic surgery gave consent for this study. They were divided into 2 groups based on the(More)
