OBJECTIVE The aim of this study was to assess the cost effectiveness of silicone and alginate impressions for complete dentures. METHODS Cost effectiveness analyses were undertaken alongside a UK single centre, double blind, controlled, crossover clinical trial. Taking the perspective of the healthcare sector, effectiveness is measured using the EuroQol (EQ-5D-3L) which provides a single inde...

In their recent paper, Chang and coauthors 1 suggest that silicone lenses should be avoided in phacotrabeculectomy on the basis of their retrospective study of cellular precipitates on intraocular lens (IOL) surfaces. Their finding of statistically increased giant cell precipitates on plate-haptic silicone IOLs (Chiron C10UB) compared with poly(methyl methacrylate) (PMMA) is consistent with the...

Abstract: A novel dust free alginate impression material was formulated and prepared, comprising an alginate polyvinylpyrrolidone and tetraflouroethylene resins, a mixture of liquid paraffin and dimethylpolysiloxane oil as the dust generation controlling agents and processed diatomaceous earth filler which was obtained from Iranian ore. No dusting was detected during the mixing of the powde...

Background: In bilateral partial edentulous condition modified Mc Lean’s Impression technique is most commonly advised, this over impression procedure may be time consuming clinically and possible errors too can be induced while recording. The purpose of this study was to determine the efficacy ofsingle custom tray using medium body elastomeric impression material overmodified Mc Lean’s impress...

BACKGROUND Dimensional accuracy when making impressions is crucial to the quality of fixed prosthodontic treatment, and the impression technique is a critical factor affecting this accuracy. The purpose of this in vitro study was to compare the dimensional accuracy of the casts obtained from one step double mix, two step double mix polyvinyl siloxane putty- wash impression techniques using thre...

OBJECTIVES To develop a novel technique to visualize dentogingival profiles by using cone beam computed tomography (CBCT) and to evaluate the accuracy of mucogingival tissue thickness measurements with CBCT, as compared with direct measurements in vitro. METHODS A silicone matrix loaded with radiopaque impression material was prepared before performing CBCT on a patient. Two dry cadaver mandi...

There are only a few published reports describing the pathology of regional lymph nodes from patients with silicone breast implants. Systematic analytical chemical verification of foreign material has not previously been reported. In this study, biopsies of regional lymph nodes from 96 patients with breast implants were studied using conventional histology as well as laser-Raman microprobe spec...

Figure 1.Maxillary PVS impression demonstrating defect in palatal region. A maxillary complete denture (CD) impression often demonstrates a defect in the palatal region of the edentulous arch. This problem commonly relates to air trapped in the impression material or mishandling of the tray seating; the bubble formed in the impression can compromise the fit of the CD or impair tissue health. On...

Replacement of missing ears is a challenging task in which extensive array of materials and techniques have been employed. This article describes a different and simplified procedure for fabricating auricular prostheses very similar to the intact left ear of the patient. A 65-year-old male patient was referred to the Department of Prosthodontics with the loss of the right ear. In this case, the...
