A portable constant current electrical stimulator with bipolar felt disk electrodes was developed for quantitative assessment of cutaneous sensibility. The new method was used in the measurement of thresholds for perception and pain in healthy volunteers. The mean values of the threshold for perception in different areas of the body varied between 1.0 and(More)
Five food samples have been analysed for a number of polycyclic aromatic hydrocarbons (PAHs) by capillary gas chromatography with flame ionization detection (GC-FID) and high-performance liquid chromatography (HPLC) with fluorescence detection. The methods give similar results and there is no significant difference in their repeatability. The capillary GC(More)
A new, versatile adapter for computed tomography-guided stereotaxis is presented. The instrument consists of a light aluminum frame, which by means of a nasion support and two ear plugs is fixed to the patient's head. Reproducibility of repeated fixations is very high. The adapter is fitted to most stereotactic frames and can be used in all adult patients.(More)
The reproducibility of a noninvasive computed tomography (CT)/magnetic resonance imaging stereoadapter was tested on 12 healthy volunteers. The adapter was easy to mount and detach without discomfort. Two repeated mountings of the adapter showed a good reproducibility in relation to the scalp. When extrapolated to a hypothetical target in the right(More)
Objective The reproducibility of clinical records of the occlusion was assessed in three dimensions using mounted casts. Three distinct areas were examined: 1) mandibular positions (intercuspal position (IP) or retruded contact position (RCP)), 2) materials used in recording the occlusion, 3) clinical variation.Design Interocclusal records were made in a(More)
PURPOSE The purpose of this study was to determine if accuracy and dimensional stability of vinyl polysiloxanes and irreversible hydrocolloids stabilized by a tray used for fixed prosthodontics, removable partial, and complete denture cases are comparable to those of waxes and record rims and if storage time (24 hours or 6 days) affects dimensional(More)
PURPOSE The purpose of this follow-up study was to quantify the change in the peri-implant mucosal level after treatment of edentulous patients with fixed prostheses on osseointegrated endosseous implants. MATERIALS AND METHODS Twenty patients were included in the study: 10 were treated in the maxilla, and 10 were treated in the mandible. Both groups had(More)
PURPOSE The purpose of this follow-up study was to evaluate the stability of the screw joint in edentulous patients 1 year after treatment with implant-supported fixed prostheses (Brånemark system). MATERIALS AND METHODS A total of 20 patients were included, 10 treated in the maxilla and 10 in the mandible. The fixed prostheses were removed approximately(More)
The aim of this study was to estimate whether the survival ratios after 20 years of fixed prosthodontics made of alginate impressions was higher, equivalent or lower, compared to the survival ratios, shown in studies, where different impression materials were used. 151 females and 104 males were screened regarding the condition and age of the restorations(More)
