The etiological factors may be mechanical, chemical and psychological, or their combinations. Dental attrision creates serious problems with masticatory and speech functions, and esthetics of the patients. Excessive occlusal wear can also cause loss of vertical dimension. This serious loss of tooth structure, requires a comprehensive restorative treatment. 45 years old female patient was admitted to our clinic with complaints of loss of aesthetics and masticatory function. First of all, the root canal treatment of the upper front teeth -all of which is vital- was performed. Then the crown lengths were extended by prefabricated posts and composite cores. The patient's occlusal vertical dimension increased by restorations of temporary acrylic crowns. The patient has been made to use these acrylic temporary crowns for 3 months to get used to the new vertical dimension. At the end of this period, the patient's upper and lower teeth were restored with metal-ceramic crowns. An occlusal splint was made for protective purposes.trinfo:eu-repo/semantics/closedAccessCrown lengtheningOcclusal vertical dimensionPost-core restorationTooth wearArticle18218018610.7126/cdj.2012.13972-s2.0-84928609012Q4
