Inclusion criteria
Inclusion criteria: • Patients = 18 years of age • Patients that reveal extensive erosive lesions (Basic Erosive Wear Examination/BEWE Index 14-18) due to exogenous (former excessive consumption of acidic drinks) or endogenous factors (exposure to gastric juice due to gastro oesophageal reflux disease (GERD) or eating disorders such as bulimia and anorexia nervosa) • Patients with severe loss (> 2 mm) of the vertical dimension of occlusion • Patients with hypersensitivity of the teeth • Patients with reduced chewing ability • Patients with impaired aesthetics • Patients compliant to fill out questionnaires on food behaviour forms • Patients that will be in need of a full-mouth rehabilitation (n=14-28 teeth per patient); Cessation of erosion progression is mandatory • Favourable and stable occlusal relationship • Sufficient height of abutment teeth (4.5 mm) • Vital and non-vital abutment teeth, which are free of any radiologic diagnosable pathological changes and which are clinically acceptable, or which exhibit a lege artis endodontic treatment • Pocket depth at the abutment teeth < 4 mm • Tooth mobility < II • Multi-root teeth furcation < 2 • Sufficient treated dentition or planned treatment in the course of the therapy (in this case, the costs are supported by the patient)
Exclusion criteria
Exclusion criteria: • Patients that reveal erosive lesions due to a history of alcohol or drug (methamphetamine/ecstasy) abuse, missing teeth, poor oral hygiene (pocket depths > 3mm, Papillary Bleeding Index > 35% or pronounced parafunctions) • Patients with allergies to any of the materials applied during the study • Patients with diseases whose general status falls into the category IV of the American Society of Anaesthesiologists/ASA classification (patients with live-threatening severe general diseases and obvious limitation of their activity) • Patients with psychiatric problems • Severe bruxism, malocclusion (deep bite, non-occlusion, cross bite) or other destructive habits • Patients without opposing dentition • Patients with acute symptoms of a functional disorder, which requires a functional pre-treatment prior to the prosthetic therapy
