Esthetic Outcomes of Implant-Supported Single Crowns Related to Abutment Type and Material: A Systematic Review.

Int J Prosthodont 2021 Mar-Apr;34(2):229-249

Purpose: To systematically review the influence of abutment material and configuration on the soft tissue esthetic outcomes of implant-supported single crowns (iSCs) after 3 years.

Materials And Methods: An electronic search on MEDLINE (PubMed) from January 2000 to July 2019 was conducted for clinical trials with no language restrictions. The focus question was: In partially edentulous patients with iSCs, does the abutment material (metal vs ceramic) or the configuration (standardized vs customized) have an effect on the soft tissue esthetic outcomes? Randomized controlled trials, controlled clinical trials, and prospective or retrospective case series with at least 10 patients and a minimum of 3 years of follow-up were included. Read More

Phys Med Biol 2021 Apr 21. Epub 2021 Apr 21.

KU Leuven, Leuven, Flanders, BELGIUM.

Patient movement affects image quality in oral and maxillofacial cone-beam CT imaging.

Genetics of HLA peptide presentation, and impact on outcomes in HLA-matched allo-HCT.

Transplant Cell Ther 2021 Apr 18. Epub 2021 Apr 18.

Internal Medicine, University of North Carolina, Chapel Hill, NC, USA. Electronic address:

Background: Minor histocompatibility antigens (mHA), which are recipient derived peptide epitopes presented on the cell surface, are known to mediate GVHD; however, there are no current methods to associate mHA features with GVHD risk. This deficiency is due in part to the lack of technological means to accurately predict, let alone confirm, the tremendous number of potential mHA in each individual transplant. Prior studies have shown that different HLA molecules present varying fractions of candidate peptide epitopes; however, the genetic "distance" between HLA matched donors and recipients is relatively constrained.
