As part of our ongoing series, “Solving Common Problems in Bite Scan Alignment,” we’ve previously explored challenges like incomplete bite scans and incorrect bites. This post shifts focus to another prevalent issue faced during dental scanning: intersections. These occur when parts of one dental arch appear to cross through the opposing arch in the digital model, creating a significant challenge in dental diagnostics and treatment planning.
What Causes Intersections in Bite Scans?
Intersections in bite scans primarily result from the dynamic nature of the periodontal ligament and the static nature of the scan. As teeth move slightly under biting pressure due to the flexibility of the periodontal ligaments, static scans may capture these positions inaccurately, leading to intersections in the rendered images.
How to Identify and Address Intersections
Intersections can be visibly identified in a bite scan by rotating and closely inspecting the scan from different angles. Here are steps to effectively manage and correct intersections:
- Inspect Your Scans: After completing a bite scan, rotate the digital model to view it from various angles. Look for areas where the scans of the upper and lower arches improperly overlap or intersect.
- Take Multiple Bite Scans: To enhance the accuracy of the scan alignment, take bite scans from both sides of the mouth. This approach allows the software to compare and reconcile data from multiple perspectives, reducing the likelihood of intersections.
- Medit Occlusion Analyzer: For complex cases or persistent issues with intersections, Medit Occlusion Analyzer can be a valuable tool. This application assesses the bite scans, provides a detailed report of potential issues, and offers tools to manually adjust the alignment if necessary.
- Communicate with Your Lab: If intersections persist despite troubleshooting, consult with your dental lab. Technicians at the lab are often highly skilled in resolving such issues and can adjust the digital model to compensate for any inaccuracies in the bite scan.
