CAD/CAM-fabricated implant-supported single crowns made from lithium disilicate and paired with zirconia implants have proved to be successful in clinical studies. But how well do they hold up over the longer term and compare with other options? A new study reports results over a five-year follow-up period. Researchers followed up annually with patients who received this treatment to determine implant survival rates and patient satisfaction, as well as how this

Although laser fluorescence has been readily studied, the results have been mixed. Therefore, a team of international researchers decided to use a new method to test the technology’s effectiveness. They published their findings in Lasers in Medical Science

Screw-retained implants fracture sooner than cement-retained ones, and fractures are more likely to occur in the premolars and molars, according to a new study on implant fractures. Although implant fracture is rare, it can have serious consequences for both clinicians and patients. Therefore, the study authors wanted to find associations between failed implants to identify potential trends and warning signs of failure. They reported their findings in the Journal of
