In this study, cone beam computed tomography (CBCT) and three dimensional (3D) stereophotogrammetry are used to compare the 3D skeletal and soft tissue changes caused by a bilateral sagittal split osteotomy (BSSO) 1 year after a mandibular advancement. Eighteen consecutive patients with a hypoplastic mandible were treated with a BSSO according to the(More)
PURPOSE To design a relevant method to compare the virtual planned implant position to the ultimately achieved implant position and to evaluate, in case of discrepancy, the cause for this. MATERIALS AND METHODS Five consecutive edentulous patients with retention problems of the upper denture received four implants in the maxilla. Preoperatively, first a(More)
PURPOSE The purpose of the study is to determine the clinically relevant accuracy of implant placement in the edentulous maxilla using computer planning and a mucosa-supported surgical template. MATERIALS AND METHODS In each of in total 30 consecutive edentulous patients suffering from retention problems of their upper denture, two or four Brånemark MkIII(More)
PURPOSE The purpose of this study was to determine the clinically relevant accuracy of implant placement in the augmented maxilla using computer planning and a mucosa-supported surgical template. MATERIALS AND METHODS Twenty-five consecutive edentulous patients with an extreme maxillar alveolar ridge resorption were treated with a bone augmentation(More)
To evaluate treatment outcomes following oral and maxillofacial surgery, pre- and post-treatment three-dimensional (3D) photographs of the patient's face can assessed, but this procedure is accurate only if the face is captured with the same facial expression every time. The purpose of this prospective study was to determine variations in the face at rest;(More)
Previous research on the accuracy of flapless implant placement of virtually planned implants in the augmented maxilla revealed unfavourable discrepancies between implant planning and placement. By using the osteosynthesis screws placed during the augmentation procedure, the surgical template could be optimally stabilized. The purpose of this study was to(More)
A healthy 72-year-old man presented with retention problems concerning the dentures in his maxilla. On account of extreme resorption, placement of implants without prior bone augmentation was not an option. The proposal was to use autologous bone harvested from the iliac crest. After a healing period of 4 months, a cone beam computed tomography scan was(More)
In the period 1 January 2008 to 1 January 2012, an implant was installed in 186 patients immediately after the removal of a maxillary incisor. Subsequent to the placement of the implant, the 2 mm gap between implant and buccal plate was filled with a bone substitute. In the case of 16 patients, in addition to a preoperative and immediately postoperative(More)
AIM To assess the feasibility of a new method to augment the three-dimensional virtual skull model with a detailed surface model of the dentition produced by intra-oral scanning, compared to the conventional triple scan procedure. MATERIALS & METHODS In four patients who were planned for bimaxillary orthognathic surgery, the conventional triple scan(More)
Orthognathic surgery has an influence on the overlying soft tissues of the translated bony maxillomandibular complex. Improvements in both function and facial appearance are the goals of surgery. However, unwanted changes to the soft tissues, especially in the nose region, frequently occur. The most common secondary change in the nasolabial region is(More)
