INTRAORAL SCANNER

Optical impressions reduce patient discomfort; IOS are time-efficient and simplify clinical procedures for the dentist eliminating plaster models and allowing better communication with the dental technician and with patients; however with IOS it can be difficult to detect deep margin lines in prepared teeth and/or in case of bleeding there is a learning curve and there are purchasing and managing costs. The current IOS are sufficiently accurate for capturing impressions for fabricating a whole series of prosthetic restorations (inlays/onlays copings and frameworks single crowns and fixed partial dentures) on both natural teeth and implants; in addition they can be used for smile design and to fabricate posts and cores removable partial prostheses and obturators. The literature to date does not support the use of IOS in long-span restorations with natural teeth or implants. Finally IOS can be integrated in implant dentistry for guided surgery and in orthodontics for fabricating aligners and custom-made devices.Intraoral scanners have eliminated issues with precision and accuracy by allowing the dentist to take and retake highly efficient 3D images of the patient's teeth.
