The aim of this research was to evaluate the reliability and validity of measurements obtained from clinical standardized occlusal photographs compared with dental cast measurements. This study comprised a consecutive sample of 16 patients (eight males and eight females, aged 15-24 years) in the permanent dentition without agenesis and/or tooth loss. A paired t-test and intraclass correlation c...

We study the domain of existence of a solution to a Riemann problem for the pressure gradient equation in two space dimensions. The Riemann problem is the expansion of a quadrant of gas of constant state into the other three vacuum quadrants. The global existence of a smooth solution was established in Dai and Zhang [Arch. Rational Mech. Anal., 155(2000), 277-298] up to the free boundary of vac...

We present an asymptotic analysis of a mesoscale energy for bilayer membranes that has been introduced and analyzed in two space dimensions by the second and third author (Arch. Ration. Mech. Anal. 193, 2009). The energy is both non-local and nonconvex. It combines a surface area and a Monge–Kantorovich-distance term, leading to a competition between preferences for maximally concentrated and m...

There are numerous intra-oral appliances that are used for many purposes in orthodontic practice. Some popular instances include those for anchorage preservation, distalizing plates, and expansion appliances. In maximum anchorage extraction cases, which are serious challenges for orthodontists, none of intra-oral devices can preserve the anchorage precisely. Butterfly arch with its unique desig...
