Occulsion and Malocclusion
Occlusion
What is Occlusion?
Occlusion is the contact of the upper and lower teeth in any jaw position.
What Proper Occlusion?
Proper Occlusion is when every tooth is perfectly fitting and straightened, from the top to the lower dental appliance. The ideal interdigitation of the teeth, in which there is no cuspal interference in lateral excursions of the mandible.
In prosthetic dentistry the simultaneous contact of all occlusal areas to prevent the tipping or rotating of the dental appliance base. The relationship of the upper and lower dental appliances, are when the teeth are brought into contact from centric relation.
Malocclusion
What is Malocclusion?
Malocclusion is any deviation from the normal occlusion of the teeth, resulting in impaired or incorrect function.
What types of Malocclusions are there?
Class 1: Relative positioning of the dental appliance are mesiodistally, normal, with malocclusions usual confined to the anterior teeth
Class 2: Retrusion of the lower jaw, with distal occlusion of the lower teeth.
Class 3. Protrusion of the lower jaw, with mesial occlusion of the lower teeth; lower incisors and cuspids lingually inclined.
How does Malocclusion Occur?
Malocclusion can occurs when there is interference and or a lack of balance between the upper and lower teeth. It can also occur after the loss of a tooth and or the addition of a filling, which in hindsight has the potential to create tremendous strain and pressure points in and around the mouth making it quite uncomfortable for the patient.
