Anterior Guidance OCCLUSION Robert L. Lee John Wright * PSG Inc. Boston Bristol London 1982 Harry C. Lundeen Charles H. Gibbs “Occlusion” by dictionary definition refers to the act of closure or the state of being closed. The literal definition of occlusion is 'the act of closure or state of being closed or shut off'. 2. Smooth anterior guidance from anterior teeth contact and posterior teeth disclusion has been described as a component of a therapeutic occlusion. The guidance provided by anterior teeth can be recorded in acrylic resin on the incisal guide block. In addition, to following and practicing the 3 golden rules! Second to a stable, seated condylar position (CR), a correct anterior guidance is the single most important factor in an optimal occlusion—one that will be steep enough to disclude the posterior teeth in any excursive movement while being concave enough to be in harmony with the envelope of function. From this position an interference-free occlusion can be developed, derived from a stable and repeatable anatomic position. Occlusion according to The Glossary of Prosthodontic Terms Ninth Edition is defined as 'the static relationship between the incising or masticating surfaces of the maxillary or mandibular teeth or tooth analogues'.. Anterior guidance for protrusive movements. In a perfected stable occlusion, protrusive movements will be guided evenly on the central and lateral incisors. Occlusion aspects in orthodontics treatment completion 79 must occlude with the lower anterior teeth and the first premolar or the second premolar (in extraction cases), aiming at disoccluding all posterior teeth (immediate anterior guidance); 5. By creating a dental bite that is free of interferences, muscle hyperactivity and posterior non-working contacts. The 3 golden rules of occlusion design (anterior guidance) are vitally important to ensure that you experience fewer dental emergencies, headaches and stress. Anterior guidance can, in effect, be transferred from the teeth to the incisal guide block of the articulator.If crowns restoring the lingual contours of the anterior teeth … Even with a bruxer, a perfected occlusion is not going to create a lot of problems with the wear if the anterior guidance is proper because there's not going to be any tendency to push or rub against a correct anterior guidance. Most importantly, the cusps of the posterior teeth will never contact during this movement. Clinical research on the effects of occlusal devices is extensive, but documentation about the actual occlusion studied is lacking. The mandibular and maxillary teeth interact and must do so in a passive manner. 1. If the joint on the side the mandible is moving away from experiences pain, it may be necessary to create non-working contacts in the occlusion of the appliance to support the joint. This often means removing any anterior guidance from the appliance if the pain is in the joint on the same side the mandible is moving towards. No interference must be present on the balancing side. 3. In human anatomy, denoting the front surface of the body; often used to indicate the position of one structure relative to another, that is, situated nearer the front part of the body.
