Intraoral photogrammetry, often abbreviated as IPG, is becoming an important technology in dental implant procedures. At SHINING 3D DENTAL, we are committed to helping clinicians understand and use this method to improve accuracy and efficiency when capturing implant positions. Here, we explain what intraoral photogrammetry is, how it works, and why it is beneficial for dental professionals and patients alike.
What is Intraoral Photogrammetry
Intraoral photogrammetry/IPG is a digital imaging technique that captures multiple high-resolution photographs inside the mouth to create precise three-dimensional models. Unlike traditional scanning methods that rely on surface mapping, IPG uses a process called triangulation based on coded reference points. These reference points are often provided by scanbodies placed on dental implants.
Scanbodies act as fixed markers, allowing the system to calculate the exact spatial location and orientation of each implant. This approach is particularly useful in cases involving multiple implants or full-arch restorations where precise implant relationships are critical.
How the IPG Workflow Works
The process starts with the clinician placing scanbodies onto the implants inside the patient’s mouth. Next, a specialized intraoral scanner, such as the ones developed by SHINING 3D DENTAL, captures a series of detailed images from different angles.
The photogrammetry software then analyzes the images and identifies the coded patterns on each scanbody. Using mathematical triangulation, it reconstructs the exact positions of the implants in three-dimensional space. This creates a digital model that includes both the implant locations and surrounding soft tissues.
Because the process relies on multiple photographs rather than a single continuous scan, it can overcome some common challenges found in traditional intraoral scanning such as stitching errors or difficulty capturing edentulous areas.
Benefits of Using Intraoral Photogrammetry
One of the main advantages of IPG is its high level of accuracy in recording implant positions. This accuracy supports the creation of well-fitting implant restorations, reducing the need for adjustments during the final fitting. A precise fit also helps maintain implant health by minimizing mechanical stress.
Additionally, IPG simplifies the workflow for clinicians. Instead of complex and time-consuming multi-angle scanning, the system quickly identifies scanbodies through coded markers, saving time during data capture. This efficiency can enhance patient comfort by shortening the appointment duration.
From a laboratory perspective, the detailed 3D models generated by IPG improve communication with the clinic and streamline the design of implant-supported prosthetics. Digital files can be shared directly, enabling faster fabrication without compromising accuracy.
Looking Ahead with SHINING 3D DENTAL
As digital dentistry continues to evolve, intraoral photogrammetry offers a practical tool for improving implant workflows. At SHINING 3D DENTAL, we integrate IPG technology into our scanner systems to provide clinicians with reliable, easy-to-use solutions.
By understanding how intraoral photogrammetry works and embracing its advantages, dental professionals can enhance their treatment planning and deliver restorations with confidence. This approach not only benefits clinical outcomes but also contributes to a smoother, more predictable patient experience.
