The use of autogenous materials to promote tissue regeneration has guided the direction of modern dentistry, and platelet-rich fibrin (PRF) is a promising biomaterial for tissue engineering. This in vitro immunohistochemical study aimed to analyze the presence of factors of endothelial growth and cell differentiation in PRF membranes by using the CD31 (endothelial cells) and CD163 (monocytes) markers. Five men and 5 women, aged between 25 and 60 years and without systemic health problems, were enrolled in the study.

- The study investigates how the melting temperatures of cobalt-chromium (Co-Cr) alloys affect the fit of implant cylinders.
- Two groups of Co-Cr cylinders were created: one with high melting temperatures (HMT) and one with low melting temperatures (LMT), alongside a control group.
- Results show that HMT cylinders had a significantly worse marginal fit compared to LMT and control cylinders, though no differences in dimensional stability were found.
Statement Of Problem: The mechanical stability of the implant-abutment connection is of fundamental importance for successful implant-supported restorations. Therefore, understanding removal torque values is essential.
Purpose: The purpose of this study was to evaluate the reverse torque values of indexed and nonindexed abutments of the Morse Taper system.
Statement Of The Problem: The connection between abutments and implants is fundamental to successful prosthetic rehabilitation, and the loosening or fracture of the parts are undesirable outcomes.
Purpose: The purpose of this study was to measure the reverse torque values of 2 different types of Morse taper implants.
Material And Methods: Ten Morse taper implants were used, with their respective abutments.
