FAQ
What is group function occlusion?
A straight answer first, then the context behind it, from the technicians who do the work.
THE SHORT ANSWER
Group function occlusion is a lateral occlusal scheme where multiple teeth on the working side , typically the canine, premolars, and sometimes the first molar , share the load simultaneously during lateral excursions. No single tooth bears the full excursive force. It contrasts with canine guidance, where the canine alone discludesthe posterior teeth. Both schemes are clinically valid; case selection drives the choice.
THE CONTEXT
What sits behind it
For restorative dentists prescribing occlusal schemes on lab cases, the distinction matters at the case-planning stage, not after delivery. Group function is often preferred when canine anatomy is compromised, when existing wear patterns suggest the patient has never functioned on canine guidance, or when implant-supported restorations require broader load distribution. A prosthodontist planning a full-arch case on natural dentition with moderate attrition will frequently specify group function to match the patient's established neuromuscular pattern.
From a lab perspective, the prescribed occlusal scheme directly shapes how the technician articulates the case and designs the lateral ramp geometry on the restorations. At Dani Dental, occlusal scheme is a required field on every crown and bridge Rx , not an afterthought. Cases arrive with the articulation set to the prescribed scheme before any ceramic layering or staining begins. That single step eliminates a common source of remakes.
If you are transitioning a patient from a failing canine guidance to group function , or rebuilding an arch where the canine is being restored simultaneously , the lab needs that context before milling begins. Sending the CBCT, the preop photos, and a brief note on the occlusal history takes under two minutes and cuts adjustment time chairside by a meaningful margin on complex cases.
