In-Vitro Investigation of Fatigue and Fracture Behavior of Transmucosal versus Submerged Bone Level Implants Used in Fixed Prosthesis

Applied Sciences, 2021
Background: The present in vitro study aimed to investigate the fatigue performance of different dental fixtures in two different emergence profiles. Biological failures are frequently reported because the problem canonly be solved by replacing a failing

PARABOLIC AND HYPERBOLIC SCREW MOTION SURFACES IN ℍ²×ℝ [PDF]

Journal of the Australian Mathematical Society, 2008
AbstractIn this paper we find many families in the product space ℍ2×ℝ of complete embedded, simply connected, minimal and surfaces with constant mean curvature H such that |H|≤1/2. We study complete surfaces invariant either by parabolic or by hyperbolic screw motions. We study the notion of isometric associate immersions.

THE LOGARITHMIC SPIRAL AND ITS SPHERICAL COUNTERPART

Journal of Industrial Design and Engineering Graphics, 2020
Logarithmic spirals are isogonal trajectories of pencils of lines. From a series of geometric consequences, we pick out a few which are relevant for kinematics: When a logarithmic spiral rolls on a line, its asymptotic point traces a straight line. Hence,

The sub-Riemannian length spectrum for screw motions of constant pitch on flat and hyperbolic 3-manifolds

Geometriae Dedicata
Let M be an oriented three-dimensional Riemannian manifold of constant sectional curvature k = 0,1,-1 and let SO(M) be its direct orthonormal frame bundle (direct refers to positive orientation), which may be thought of as the set of all positions of a small body in M.
