Anterior guidance: group function/canine guidance. A literature review

Anterior guidance, which can be categorized as group function or canine guidance, is essential for esthetics, phonetics, and mastication. This article reviews the historical development and philosophies of both occlusal schemes. There is no scientific evidence that supports one occlusal scheme over the other. Where anterior guidance must be reestablished or where it changes, there currently appear to be more authorities who favor canine guidance over group function.
