Tooth wear - Full-mouth reconstruction
Because the occlusal vertical dimension is related to the teeth, tooth wear is suspected to cause modifications in a dental restoration. Physiological loss of dental enamel structure has been reported as varying from 0.02 to 0.04 mm per year. It is not considered an issue if the patient does not relate discomfort. However, processes such as attrition, abrasion and erosion (especially these combinations) can cause severe tooth wear and generate symptoms categorized as pathological.
Turrell described various methods to assess the occlusal vertical dimension. The phonetic approach, based on correlation of the inter occlusal distances (freeway space), position of the occlusal plane and the position of the tongue relative to the teeth during speech is a widely used and reported method. However, no method is considered completely accurate. The clinical experience of the dental team usually has the major role in treatment processes.
