Comprehensive treatment addresses the entire masticatory system (ie. muscles, joints, and bite). All too often, dental treatment conforms to the existing patient’s masticatory system regardless of existing pathology.
If there are contributing factors such as malocclusion (a bad bite) or other pathological findings to the patients chief concern, it is often better to treat the cause of the problem prior to addressing the symptoms (the chief concern). That is why we diagnose before we treat.
