. AbstrAct The aim of the present study was to evaluate both ZAAG and OT REVERSE / 3 attachments retaining complete mandibular overdentures supported by two Legacy implants regarding both periimplant bone and residual ridge resorpotion and maintenance complications in patients with limited interarch space during a 2 year followup period. The two implants were placed in the canine region. Mandib...

PURPOSE The aim of this study was to compare the retention and stability of the Nobel Biocare standard ball (NBS), Nobel Biocare 2.25-mm-diameter ball (NB2), Zest Anchor (ZA), Zest Anchor Advanced Generation (ZAAG), Sterngold ERA orange (SEO), and Sterngold ERA white (SEW) attachments on an implant-retained overdenture model. MATERIALS AND METHODS The attachments were tested using 2 permanent...

STATEMENT OF PROBLEM The specific degree of retention for overdenture attachments is unknown in relation to design, location, and alignment to supporting dental implants. PURPOSE The purpose of this study was to evaluate the initial retention characteristics of 5 implant maxillary overdenture designs under in vitro dislodging forces. MATERIAL AND METHODS A simulated edentulous maxilla was f...

We prove a local version of a (global) result of Merle and Zaag about ODE behavior of solutions near blowup points for subcritical nonlinear heat equations. As an application, for the equation ut = ∆u+V (x)f(u), we rule out the possibility of blowup at zero points of the potential V for monotone in time solutions when f(u) ∼ u for large u, both in the Sobolev subcritical case and in the radial ...

In this paper, we provide a thorough investigation of the blowing up behavior induced via diffusion solution following non-local problem: [Formula: see text] where is bounded domain in with smooth boundary such problem derived as shadow limit singular Gierer–Meinhardt system, Kavallaris and Suzuki [On dynamics parabolic equation arising from Nonlinearity (2017) 1734–1761; Non-Local Partial Diff...
