CAD/CAM is an acronym that stands for computer-aided design/computer-aided manufacturing.
A sinus lift, also sometimes referred to as sinus augmentation, is performed when there is a need to increase the amount of bone structure in the molar and/or pre-molar section of the upper jawbone. This surgery is usually performed for the purpose of supporting a dental implant, which can be placed once the bone has healed and shows sufficient density and mass to support the implants.
