Brief summary
Prospective observational study with 7-year follow up. 55 patients are included with moderate to severe tooth wear, whereby through informed consent the decision was taking to monitor the patients. At the baseline and 1, 3 5, and the 7-year recall digital 3D scans will be made, which will be compared and subtracted.
Detailed description
Prospective observational study with 7-year follow up. 55 patients are included with moderate to severe tooth wear, whereby through informed consent the decision was taking to monitor the patients. At the baseline and the 5-year recall digital 3D scans will be made, which will be compared and subtracted. Per tooth the loss of material is measured in maximum loss in height (µm) and volume (mm3) per year, using best fit alignment and 3D subtraction. The loss of tooth material will be analyzed using descriptive statistics and possible effects of jaw type, tooth type and cusp type will be analyzed using multi level regression models. The use of index teeth will be analyzed.
