Vertical marginal gap evaluation of PEEK and Zirconia crowns using extra-oral scanner and CAD/CAM systems (An Invitro study).

Erbil Dental Journal, 2022
Background and objective: Selecting a material with lower marginal gap is the key factor for a successful dental prosthesis. With less marginal gap of the crown the aggregation of bacterial plaque at the gingival margins, that result in periodontal ...

To evaluate the marginal adaptation of porcelain fused to metal crown with different base metal alloys

Journal of Pharmacy and Bioallied Sciences, 2021
Introduction: The success of any restoration depends on the marginal seal. The adaptation of castings, luting cement, and the surface structures of the margins are all important factors in achieving marginal seal.

c-axis Optical Conductivity in Cuprates

, 1999
We investigate the c-axis optical conductivity and d.c. resistivity of cuprate superconductors in the normal state. Assuming that the interlayer hopping is incoherent we express the conductivity with planar spectral functions obtained (i) from angle ...

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.
