During clinical practice, when performing prosthetic rehabilitation with single crowns, improper reproduction of the dental contour by the dental laboratory is a common occurrence. Therefore, the present study evaluated the fidelity of the reproduction of the buccal contour in an upper left canine performed by three Dental Prosthesis Technicians (DPT) using the indirect laminate veneer techniqu...

The analysis of palatal vault morphology and maxillary dental arch shape was carried out in the sample of 42 Down syndrome (DS) patients with trisomy 21. The data were compared to those of healthy controls from the same population matched for age and sex. Palatal morphology and upper dental arch shape were studied on hard plaster casts of the patients and controls. No sexual dimorphism in palat...

UNLABELLED There is controversy in the literature about possible interaction of the respiratory mode with the facial and dental structures. OBJECTIVES The aim of this study was to perform a longitudinal assessment of the changes in facial and dental structures in Angle's Class II, division 1 malocclusion individuals, divided according to the respiratory pattern (predominantly nasal or mouth),...

ABSTRACT The purpose of this study was to analyze the overjet and overbite behavior during eruption of the upper permanent incisors. Fourth-eight plaster casts of 16 patients from ages 6-13 years were appraised longitudinally. It was found that the overjet remains constant, starting at the eruption of the upper permanent central incisors until eruption of the upper permanent canine teeth, while...

The architecture of the subterranean nests of the ant Odontomachus brunneus (Patton) (Hymenoptera: Formicidae) was studied by means of casts with dental plaster or molten metal. The entombed ants were later recovered by dissolution of plaster casts in hot running water. O. brunneus excavates simple nests, each consisting of a single, vertical shaft connecting more or less horizontal, simple cha...

OBJECTIVE The use of stone and plaster study models is an integral part of any dental practice and is required for research. Storage of study models is problematic in terms of space and cost. Ayoub et al.(1) introduced a new technique based on the recent advances in stereophotogrammetry for archiving dental study models in a digital format. However, assessment of the accuracy of the generated t...

Cleft lip and palate is the most common asymmetric congenital condition of orofacial region, which also finds its reflection in dental anomalies. The aim study was to present asymmetries front region maxilla cleft patients. Materials Methods: We analyzed plaster casts panoramic X-rays 154 patients with total clefts 151 healthy individuals. patients’ age ranged between 7.1 20 years (mean 13.18)....

Background: The present study was conducted for assessing and comparing flexural strength in two types of denture base resins. Materials & methods: A total 20 acrylic specimens were made. Stainless steel dies Twenty fabricated using these stainless dies. metal flasked dental plaster to complete the flasking procedure. retrieved create mold space specimen. All randomly divided into groups as...

The design of bioactive plasters is major interest for the amelioration dental and bone cements. In this article, a one pot environmentally friendly strategy based on addition cheap polyphenol-tannic acid (TA) or main phenolic constituent TA, namely pyrogallol (PY)- able to interact with calcium sulfate proposed. Tannic not only modify morphology obtained plaster+TA/PY composites but part it re...

BACKGROUND The influence of surgery on growth and stability after treatment in patients with cleft lip and palate are topics still under discussion. The aim of the present study was to investigate the influence of early lip closure on the width of the alveolar cleft using dental casts. METHODS A total of 44 clefts were investigated using plaster casts, 30 unilateral and 7 bilateral clefts. Al...
