Peri-implant cell differentiation in delayed and immediately-loaded dental implant: A mechanobiological simulation.

Objective: This study aimed to investigate the effect of immediate versus delayed dental implant placement strategies on cell differentiation in a dental callus.

Design: The implant was placed in the mandible with two nearby teeth using an idealized two-dimensional finite element model. Eight weeks after surgery, the mechanobiological modeling of healing was used to estimate cell differentiation.

Intelligent modeling and optimization of titanium surface etching for dental implant application.

Acid-etching is one of the most popular processes for the surface treatment of dental implants. In this paper, acid-etching of commercially pure titanium (cpTi) in a 48% HSO solution is investigated. The etching process time (0-8 h) and solution temperature (25-90 °C) are assumed to be the most effective operational conditions to affect the surface roughness parameters such as arithmetical mean deviation of the assessed profile on the surface (R) and average of maximum peak to valley height of the surface over considered length profile (R), as well as weight loss (WL) of the dental implants in etching process.
