Comparative Evaluation of the Accuracy of Dynamic Navigation and Free Hand Methods During Zygomatic Implant Placement: A Randomized Controlled Trial.

To assess and compare the precision and predictability of zygomatic implants in atrophic maxilla using conventional and dynamic navigation methods. This study was a randomized controlled clinical trial conducted in patients requiring zygomatic implant placements in the atrophic maxilla. Forty zygomatic implants were placed in systemically healthy individuals.

Hydrolytically Degradable Microgels with Tunable Mechanical Properties Modulate the Host Immune Response.

Hydrogel microparticles (microgels) are an attractive approach for therapeutic delivery because of their modularity, injectability, and enhanced integration with the host tissue. Multiple microgel fabrication strategies and chemistries have been implemented, yet manipulation of microgel degradability and its effect on in vivo tissue responses remains underexplored. Here, the authors report a facile method to synthesize microgels crosslinked with ester-containing junctions to afford tunable degradation kinetics.
