Users of dental zirconia are really spoilt for choice these days. Countless manufacturers offer zirconia materials that differ in their mechanical and optical properties and indication range. What is not apparent at first sight is that the available products also differ with respect to the quality of the CAD/CAM blanks offered. Blank quality is highly dependent on the quality of the raw materials and is affected by different aspects during raw material processing, pressing and pre-sintering. This has a huge impact on the surface quality, edge stability, fit and processing requirements of milled restorations.
GUANGZHOU, China: Immediate loading of dental implants has become a popular option because it shortens treatment time, improves aesthetics and increases patient acceptance. Yet, up until now, it has remained unclear whether immediate loading can achieve equal clinical outcomes to early or conventional loading. In a review, researchers from Sun Yat-sen University in Guangzhou have compared the efficacy of immediate loading versus early or conventional loading of dental implants in patients treated with fixed prostheses. They found that immediate and conventional loading show a difference in implant survival rates.
