We have a patient we have treatment planned for an All-on-4 in the maxilla. He is retaining his teeth in the mandible where he has second premolar to second premolar and one second molar. In designing the occlusion, I am going to use canine guidance and have the maxillary anterior teeth not make contact in CR/MI. The patient currently has canine guidance. In CR/MI, the posterior teeth will support the occlusion. Is this a sound design of the occlusion? One paper recommends occlusion only on the anterior teeth, but this does not sound right to me. Also what kind of occlusal design should I use for the transitional implant appliance?
