Objectives Dental erosion, which is defined as the gradual but irreversible loss of hard tissue is a major dental issue as it may be linked to systemic diseases such as eating disorders or gastroesophageal reflux (GERD), giving rise to difficulties in diagnosis.
In both pathological forms, the presence of gastric juices in the oral cavity causes the erosion of the palatal surfaces of the upper elements, often associated with variable sensitivity; carious lesions are generally not associated. Erosions associated with gastroesophageal reflux are often associated with mucosal irritation, oral ulcers and altered taste. It may be due to mechanical or chemical causes, which often lead to problems in treatment.
Compared to traditional classifications, the ACE classification sees these lesions divided mainly related to the anterior sector and to the therapeutic intervention strategy. Early diagnosis is crucial to maximize therapeutic alternatives.
The treatment of erosions is closely related to the amount of enamel and dentinal tissue involved as well as to the vertical dimension to be obtained in order to obtain satisfactory aesthetic results for the patient. Best erosion treatment involves a multi-disciplinary team and may range from direct composite reconstructions and fixed prostheses to innovative indirect reconstruction systems that aim at preserving as much tissue as possible. The new CAD/ CAM technology offers important advantages in terms of result forecasting, accuracy, precision and better patient-dentist communication.
The principle aims of treatment are aesthetic rehabilitation, recovery of functional mastication, establishment of the correct vertical dimension and achievement of stable and reproducible outcomes. In this regard, a multidisciplinary treatment that involves various professional figures would seem to guarantee good and predictable results.
Materials and methods The present clinical report describes the treatment of asymptomatic dental erosion in a patient with eating disorders associated with bruxism and cervical myalgia. The patient requested esthetic rehabilitation without invasive interventions. A multi-disciplinary approach included esthetic analysis which was followed by posture assessment using a stabilometric platform and a podoscope.
A modified 3-step rehabilitation technique was supported by digital technology. Composite restorations were inserted in the posterior areas and double veneers in the anterior. The outcome was stable and easy to monitor.
Results and conclusions The main objectives of prosthetic rehabilitation are preserving as much residual dental tissue as possible and achieving stable occlusal rehabilitation with a multidisciplinary approach, involving dentists, physiatrists and posturologists. Treatment depends on careful assessment of postural and temporal-mandibular abnormalities, as well as tooth damage.
A multidisciplinary approach together with the advantages offered by CAD/CAM technology provides acceptable, predictable outcomes when treating dental erosive lesions. It is often particularly problematic to propose invasive therapeutic solutions, in the absence of relevant clinical symptoms.
New technologies, together with adhesive strategies in the prosthetic field, allow the partial overcoming of this problem.
Clinical significance The proposed treatment represents a valid alternative to more invasive prosthetic reconstructions and highlights the importance of the multidisciplinary approach to the treatment of dental erosions.
