Photogrammetry in Dentistry: A Case Study from Bristol CADCAM

In the first case, the implant scan was submitted using a traditional intraoral scanner (IOS) and scan bodies. As you can see the images, we couldn’t confirm the true orientation of the scan bodies because the IOS data was unreliable.

Unfortunately, this led us to the tough decision of rejecting the case from Bristol Crown. Given the lack of accurate information, we felt it was essential to prioritise the bar’s fit and functionality, so we opted for caution in this instance.

On the other hand, we had a second case using an IOS paired with photogrammetry technology. This allowed us to capture the implants’ orientation and position accurately, making the case processing smooth and efficient. The outcome was a first fit without needing a verification jig, adjustments, or remakes.

This comparison underscores the exciting potential of photogrammetry in modern dentistry. Taking the guesswork out of the equation equips labs and clinicians with the accuracy essential for navigating complex restorations, leading to better outcomes for everyone involved.
