This paper presents a research project aiming at designing a Virtual Articulator in order to simulate and analyze mandibular movements of the human jaw. Its main goal is to improve the design of dental prostheses, adding kinematic analysis to the design process. First, plaster models are scanned. Second, the type of articulator is selected. Third, the prosthesis is statically modelled. Fourth, ...
The aim of the present study is to evaluate results treatment with DENT@LIGN digital aligners by comparative analysis between printed virtual 3D motivational models, obtained from plan, and conventional plaster casts, end orthodontic treatment.
 We measured evaluated 136 (69 upper 67 lower dental arch) casts 72 patients models same patients. data was statistically.

An inner tube was inflated and then surrounded with plaster wool and plaster-of-Paris bandages. The plaster and the wool were next progressively divided. There was no significant reduction of the pressure inside the tube until both the plaster and the wool had been divided and separated from the inner tube along the entire circumference. These findings demonstrated that wool and plaster applied...
The physical properties of plaster bandages are a very important factor in achieving the basic functions of immobilization (maintaining bone fragments in the best possible position), which directly affects the speed and quality of fracture healing. This paper compares the differences between the physical properties of plaster bandages (mass, specific weight, drying rate, elasticity and strength...
Orthopaedic casts are used to treat fractures, provide pain relief and support, and correct deformities (RCN 2000, Larsen 2002, Dandy and Edwards 2003, Nielsen and Ricketts 2005). Several different types of material are available for orthopaedic casts, including plaster of Paris, semi-rigid non-fibreglass (softcast), and a variety of resin-based synthetic materials such as rigid fibreglass. Pla...
OBJECTIVE To compare dental plaster model (DPM) and cone-beam computed tomography (CBCT) in the measurement of the dental arches, and investigate whether CBCT image artifacts compromise the reliability of such measurements. MATERIALS AND METHODS Twenty patients were divided into two groups based on the presence or absence of metallic restorations in the posterior teeth. Both dental arches of ...
Hair and teeth are appendages of ectodermal origin, and there are common molecular backgrounds involved in their formation. To date, it has been revealed that a non-synonymous polymorphism in EDAR has effects on the morphological variation in both hair and teeth. Previous association studies have confirmed that single-nucleotide polymorphisms (SNPs) in/near THADA, FRAS1, WNT10A, NAF1 and FGFR2 ...
