The purpose is to evaluate the clinical and biological behavior of full coverage restorations on teeth prepared without finish line.
This prospective study included 149 teeth treated using biologically oriented preparation technique (BOPT). The sample (149 teeth) was divided into two groups: Seventy
Project title: Platelet rich fibrin (PRF) membranes in lateral alveolar ridge augmentation.
Background Tooth loss induce extensive resorption of the alveolar ridge, thereby compromising implant placement in a correct anatomical position. Therefore, various procedures for alveolar ridge augmentation
Feasibility, descriptive single arm open-label interventional trial lasting 6 weeks. The study will recruit 36 CKD patients at the outpatient clinic with: age between 18 to 85 years; glomerular filtration rate < 29 ml/min/1.73 m2 and not on dialysis; serum K > 5.1 mmol/L or in previous use of sodium
As secondary objectives, the study aims:
- to establish the norms of concentrations of free TE and nanoparticles for some forty of elements (in particular Chrome, Cobalt, Nickel, Titanium, Tantalum, Zirconium, Tungsten, Gold, Silver, Mercury, Molybdenum, Strontium ...) in different materials (blood,
Dental implants are anchored in jawbone through a direct bonding between bone and the implant. Success and survival of an implant do, however, not depend solely on osseointegration. A soft tissue, which surrounds the transmucosal part of a dental implant, separates the peri-implant bone from the
The Programmed cell death protein 1 (PD1)/Programmed death-ligand 1 (PD-L1) axis is an important immune checkpoint for T cell activation that is used by tumors to evade the host immune response. Blocking signaling with the PD-L1 antibody MPDL3280A results in ongoing T cell activity and can induce
Many of these tests and procedures are likely to be part of regular cancer care and may be done even if it turns out that you do not take part in the research study. If you have had some of these tests or procedures recently, they may or may not have to be repeated.
- A medical history, which
The aim of this cross-sectional study is to utilize the paper strip-based peri-implant crevicular fluid (PICF) sampling technique to evaluate the influence that transmucosal abutment biomaterials of either titanium or zirconium oxide, which have been in situ for greater than six months, have in the
Introduction
Long-term prospective studies demonstrate a high success rate of Straumann implants in partially or fully edentulous patients both with early and conventional loading (Salvi et al. 2004, Lambrecht et al. 2003, Cochran et al. 2002, Weber et al. 2000, Buser et al. 1997). Before the
