INTRODUCTION There is a paucity of data regarding the risk of deep vein thrombosis during hip plaster cast immobilisation. The purpose of this article was to review the available evidence regarding the incidence of symptomatic venous thromboembolism (VTE) during hip plaster cast immobilisation. METHODS AND MATERIALS All papers describing hip plaster cast immobilisation published in the Englis...

The aim of this study is to evaluate the validity of the use of digital models to assess tooth size, arch length, irregularity index, arch width and crowding versus measurements generated on hand-held plaster models with digital callipers in patients with and without malocclusion. Studies comparing linear and angular measurements obtained on digital and standard plaster models were identified b...

AIMS AND OBJECTIVE The aim of the study was to evaluate the reliability of cone beam computed tomography (CBCT) obtained image over plaster model for the assessment of mixed dentition analysis. MATERIALS AND METHODS Thirty CBCT-derived images and thirty plaster models were derived from the dental archives, and Moyer's and Tanaka-Johnston analyses were performed. The data obtained were interpr...

A Portland cement plaster wall system has many positive features, but one of the physical properties that it does not possess is flexural strength. It is because of the inability of the Portland cement plaster membrane to bend or flex that glass fiber strands were used in Portland cementbased plaster. There are various types of synthetic fibers on the market that will provide flexural strength ...

The purpose of this prospective study was to compare three different ways of conservative management of isolated fractures of the ulnar shaft: immediate mobilisation, below-elbow plaster cast and above-elbow plaster cast immobilisation. Over a 24-month period, 102 minimally displaced isolated fractures of the distal two-thirds of the ulnar shaft were treated on an outpatient basis. Thirty-two f...

OBJECTIVES The accuracy and reliability of plaster models and digital models acquired with two different surface laser scanners were tested by means of three methods: measurement with calipers, digital measurement with proper software and superimposition of the digital models. METHODS Thirty plaster models with permanent dentition that met the inclusion criteria were selected and scanned with...

BACKGROUND Reverse flow sural neurocutaneous flap has been utilized more frequently during the past decade to cover vital structures around the foot and ankle area. The potential advantages are the relatively constant blood supply, ease of elevation and preservation of major vascular trunks in the leg. The potential disadvantages remain venous congestion, donor site morbidity and lack of sensat...

PURPOSE Dental measurements have been commonly taken from plaster dental models obtained from alginate impressions can. Through the use of an intraoral scanner, digital impressions now acquire the information directly from the mouth. The purpose of this study was to determine the validity of the intraoral scans compared to plaster models. MATERIALS AND METHODS Two types of dental models (intr...

PURPOSE Plaster casts can cause burns. Synthetic casts do not. Composite plaster-synthetic casts have not been thoroughly evaluated. This study analyzed the temperature from plaster casts compared with composite casts in a variety of in vitro conditions that would simulate clinical practice. METHODS A Pyrex cylinder filled with constant body temperature circulating water simulated a human ext...
