The following review investigates the term and concept of the globulomaxillary cyst as a correct clinico-pathological diagnosis to describe a so-called fissural cyst said to be caused by epithelial entrapment between the nasal and maxillary process. After analyzing the available literature it has to be concluded that neither from an embryologic nor from a(More)
In the present study, dose measurements have been conducted following examination of the maxilla and mandible with spiral computed tomography (CT). The measurements were carried out with 2 phantoms, a head and neck phantom and a full body phantom. The analysis of applied thermoluminescent dosimeters yielded radiation doses for organs and tissues in the head(More)
Cone beam computed tomography allows high quality 3D images of cranio-facial structures. Although detail resolution is increased, x-ray exposition is reduced compared to classic computer tomography. The volume is analysed in three orthogonal plains, which can be rotated independently without quality loss. Cone beam computed tomography seems to be a less(More)
A retrospective analysis of sinusfloor elevation and implantation should evaluate in a sense of quality control the clinical results and complications during or after sinusfloor elevation. In our institution we performed 98 sinusfloor elevations in 80 patients (44 women, 36 men) between August 9, 1995 and November 18, 2002. In those elevated sinuses, 201(More)
The odontogenic keratocyst is the third most common cyst of the jaws, after the follicular and radicular cyst. Keratocysts most commonly occur as single lesions in the jaw of otherwise healthy persons. Multiple odontogenic keratocysts are a well-recognized feature of the nevoid basal cell carcinoma syndrome. The mandible, especially the third molar region,(More)
Radiation dose delivered from the SCANORA radiography unit during the cross-sectional mode for dentotangential projections was determined. With regard to oral implantology, patient situations of an edentulous maxilla and mandible as well as a single tooth gap in regions 16 and 46 were simulated. Radiation doses were measured between 0.2 and 22.5 mGy to(More)
BACKGROUND Printing of templates for guided surgery represents an alternative to laboratory manufactured templates. PURPOSE To determine the technical accuracy of a virtually designed and printed surgical template for guided implant surgery based on a surface scan of a cast model using the coDiagnostiX™ software. MATERIALS AND METHODS Cast models and(More)
Cone-Beam Computed Tomography (CBCT) has been introduced in 1998. This radiological imaging procedure has been provided for dentistry and is comparable to computed tomography (CT) in medicine. It is expected that CBCT will have the same success in dental diagnostic imaging as computed tomography had in medicine. Just as CT is responsible for a significant(More)
A retrospective analysis of intra- and postoperative complications with special regard to infections should give information about the success rate of our antiseptic treatment procedure when removing third molars. 3,980 third molars were surgically removed between July 1, 1992 and June 30, 1999. Dates were sampled from the patient medical histories (963(More)
OBJECTIVE Higher life expectancy has lead to an increase of elderly patients in dental practices, thus also causing an increase in high-risk cardiovascular patients. STUDY DESIGN In all, 3012 patients had oral surgery with local anesthesia at the Department of Oral Surgery, Oral Radiology and Oral Medicine at the University of Basel. The Colin BP 306(More)
