The Randomized Shortened Dental Arch Study: Tooth Loss [PDF]
, 2010 The evidence concerning the management of shortened dental arch (SDA) cases is sparse. This multi-center study was aimed at generating data on outcomes and survival rates for two common treatments, removable dental prostheses (RDP) for molar replacement ...

Vanishing line for the descent spectral sequence [PDF]
arXiv, 2001 For a surjective and proper map f: X -> Y there is a spectral sequence, called descent spectral sequence, abutting to the cohomology of Y with coefficients in a sheaf F. We prove that if the fibers of the map f satisfy some connectivity condition then the spectral sequence has a vanishing line.

Effect of CAD/CAM Abutment Height and Cement Type on the Retention of Zirconia Crowns
Implant Dentistry, 2018 Purpose: To evaluate Ti-Base abutment height and cement type on the retentiveness of zirconia-based restorations. Material and methods: Four millimeter (tall) and 2.5-mm-height (short) abutments along with temporary (provisional), glass ionomer (Meron ...

Evaluation of contiguous implants with cement-retained implant-abutment connections. A minipig study [PDF]
Journal of Osseointegration, 2014 Aim: The presence of a microgap at the implant-abutment interface may permit bacterial contamination and lead to bone resorption, interfering with papillae formation.

Effects of abutment-implant combinations with different elastic moduli on osteogenic performance
工程科学学报, 2019 Many factors affect the success of dental implant surgery, such as surgical trauma, excessive chewing pressure, material performance mismatch, and improper abutment-implant connection.

Cohomology of the Grothendieck construction [PDF]
Manuscripta Math. 120 (2006), no. 2, 151-162, 2005 We consider cohomology of small categories with coefficients in a natural system in the sense of Baues and Wirsching. For any funtor L: K -> CAT, we construct a spectral sequence abutting to the cohomology of the Grothendieck construction of L in terms of the cohomology of K and of L(k), for k an object in K.

BioMed Research International, 2018 Purpose Instead of original abutments, compatible abutments are often selected for financial reasons. The present study aimed to evaluate mechanical outcomes, microleakage, and marginal accuracy at the implant-abutment interface of original versus ...

Filtrations on instanton homology [PDF]
arXiv, 2011 In earlier work of the authors, the Khovanov complex of a knot or link appeared as the first page in a spectral sequence abutting to the instanton homology. The quantum and (co)homological gradings on Khovanov homology do not survive as gradings, but we show that they survive as filtrations.
