About

Intra oral scanning can perform a full digital workflow right on the patient's mouth. Recently an intra-oral photogrammetry scanner has been introduced in the market that can make intra-oral tissue scanning in addition to a built-in photogrammetry technology so that it can capture fixture locations through special intra-oral scan flags.

Full description

Intraoral scanning had several advantages to intraoral direct scanning, including less storage and transportation needs, faster scanning times, and increased patient comfort. The intraoral scan bodies are used as digital fixture locators when using IOSs for implant impressions.

Photogrammetry is the science and technology of obtaining reliable information about physical objects through the process of recording, measuring, and interpreting photographic images and patterns of electromagnetic radiant imagery. The utilization of photogrammetry in the dental field leads to exclusion of intraoral dental and gingival anatomies while scanning the implant coordinates. In addition, no need for stitching during full arch implant scanning which is reflected in the trueness and precision of the scanned object. Exclusion of unstable mucosa during scanning and avoidance of stitching make the passive seating of implant prosthesis a more predictable procedure especially when compared with intra-oral scanning only.

Up to this moment, all photogrammetry systems available in the market are considered extraoral systems that require an additional impression for soft tissue capture whether conventional or digital. Recently an intra-oral photogrammetry scanner (IPS) has been introduced in the market that can make intra-oral tissue scanning in addition to a built-in photogrammetry technology so that it can capture fixture locations through special intra-oral scan flags.
