Good Scans
- Upper and lower occlusal surfaces have no missing data, no lifted scans, and good markings all over the surface.
- Upper and lower intaglio surfaces have no missing data, no lifted scans, and good markings all over the surface.
- Scan traces from the 2nd molar to the 2nd molar area and captures identifiable markings to use for alignment.
- Proper alignment with the bite shows an accurate relationship between the two arches.
Bad Scans
- The intaglio surface does not align with the buccal surface. The result is a misaligned bite.
- Misalignment between the occlusal and buccal surfaces, as well as missing data on the intaglio portion, results in an inaccurate bite and will affect the denture fit.
- Misalignment on the occlusal surface of the wax bite rim results in an inaccurate bite.
