Abstract

Objectives

To analyze the effects of occlusal laser appliance when used by newly-graduated dentists, by measuring the occlusal rim namely the intersection angle between reference plane and occlusal plane, and comparing the results with Fox plane-guide.

Methods

The wax occlusal rims were fabricated on manikins by 15 newly-graduated dentists with Fox plane-guide and occlusal laser appliance respectively, and the occlusal rims were measured and compared.

Results

There was no statistically significant differences (t = 0.618, P = 0.542) between Fox plane-guide group (0.7 ± 0.3)° and occlusal laser appliance group (0.6 ± 0.4)° in the anterior area, while it was statistically significant (t = 3.302, P = 0.007) between Fox plane-guide group (3.1 ± 2.1)° and occlusal laser appliance group (1.4 ± 0.8)° in the posterior area. The intersection angles in occlusal laser appliance group were smaller than that in Fox plane-guide group.

Conclusion

It is effective to make occlusal rims with Fox plane-guide or occlusal laser appliance by newly-graduated dentists, and it is more efficient to use occlusal laser appliance for the posterior occlusal rims.
