Can an increase in abutment screw length enable biomechanical advantages for implants with increased crown height space?

Journal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this finite element analysis (FEA) study was to investigate how screw length and crown height affect the stresses generated in the implant‐abutment complex and alveolar bone for anterior single implants and whether the use of longer abutment screw would compensate for increased stresses originated from increased crown ...

RESULTS OF EDGE ADAPTATION OF MONOLITHIC ZIRCONIA CROWNS

Actual problems in dentistry, 2019
Subject. Edge clearance and mechanical strength are important factors for selecting all-ceramic zirconia crowns. The article presents the results of evaluating the regional adaptation of single monolithic zirconia crowns mounted on premolars and molars made using the CAD/CAM system. Objectives — a clinical assessment of the edge conformity and absolute

Optical stability of 3D‐printed and milled zirconia after artificial aging and immersion in liquids: An in vitro study

Journal of Prosthodontics, EarlyView.
ABSTRACT Purpose To assess the impact of artificial aging and immersion in common liquids on the optical properties of 3D‐printed and milled zirconia. Materials and Methods Monolithic zirconia discs (N = 100) were fabricated using two methods: 3Y‐TZP for milling (e.max ZirCAD LT BL, Ivoclar Vivadent) and printable 3Y‐TZP material (LithaCon 3Y 230) for ...

Deterministic coupling of a single silicon-vacancy color center to a photonic crystal cavity in diamond

, 2014
Deterministic coupling of single solid-state emitters to nanocavities is the key for integrated quantum information devices. We here fabricate a photonic crystal cavity around a preselected single silicon-vacancy color center in diamond and demonstrate ...
