Background: Chucks typically use a friction fit design to grip the circular shank of the bur. ProDrive Systems Inc. developed a triangular chuck locked bur.
Objective: To compare speed, smoothness of cut, bur jams or breaks between the original circular(OEM) or ProDrive(PD) turbine assemblies.
Materials and Methods: Kavo 635B, Star 430, and Midwest Tradition handpiece designs were tested on an Engineering Test Platform using Macor blocks. Sixty cuts were performed per handpiece, for a total of one hundred and eighty cuts per handpiece design. The cuts were photographed using a dissecting microscope. Statistical analysis was performed using ANOVA and Chi-squared tests.
Results: No overall improvement in speed was seen, however individual handpiece variation was observed. The Kavo-PD broke less often than Kavo-OEM combination. No differences were noted from a bur jam standpoint.
Conclusion: Our results do not support the claims made by ProDrive of being superior to the OEM chuck.
