Abstract:

The dental industry is undergoing rapid digital transformation, driven by innovations that enhance diagnostic precision, treatment planning, and restorative outcomes. Traditional analog methods—such as physical impressions and two-dimensional imaging—are being replaced by digital workflows utilizing intraoral scanning, cone-beam computed tomography (CBCT), and computer-aided design/manufacturing (CAD/CAM) technologies. While intraoral scanners have revolutionized single-tooth and limited-span restorations, they struggle with accuracy in full-arch implant cases due to cumulative stitching errors, poor soft-tissue detail, and limitations in maintaining line-of-sight.

Photogrammetry has emerged as a solution for capturing highly accurate implant positions using coded markers. Extraoral photogrammetry (EPG) devices offer micrometer-level precision but require separate soft-tissue scans, complex workflows, and high costs, limiting widespread use. Intraoral photogrammetry (IPG) addresses these limitations by integrating photogrammetric precision and intraoral scanning into a single device. IPG allows clinicians to capture both hard and soft tissue in one workflow, improving accuracy, reducing chair time, and eliminating the need for data merging.

Report includes case documentation demonstrating how IPG enhances surgical and restorative workflows, maintains vertical dimension of occlusion (VDO), and ensures predictable outcomes. IPG is setting a new standard for accuracy, efficiency, and patient satisfaction in complex implant dentistry.  Full Article
