Computer‐aided design of anterior guidance with a modified patient‐specific motion technique in anterior implant‐supported single crowns: A multicenter crossover trial
Randomized trial compares CAD anterior guidance to digital articulator in implant-supported crowns, indicating improved outcomes.
Key Points
This research aims to evaluate the clinical effectiveness of CAD anterior guidance using a modified patient-specific motion technique compared to traditional methods.
Randomized crossover design involving 63 patients at three hospitals
Two crowns per participant designed with modified PSM and a digital articulator
Statistical analysis using paired t-test and Wilcoxon signed-rank test
Test group had significantly lower maximum occlusal adjustment distance (263.4 µm vs. 362.2 µm, p = 0.001)
Reduced adjustment time and area with improved satisfaction levels for patients and dentists (p < 0.050)
42 test group crowns selected vs. 21 control crowns (p = 0.008)
