Abstract
Tooth wear is defined as the progressive loss of a tooth’s surface due to actions other than those which cause tooth decay or dental trauma. It is a pathological condition with an increasing prevalence among young people. The aim of this article is to describe an alternative treatment modality to rehabilitate the anterior guidance by a minimally invasive interdisciplinary ortho-restorative treatment. Two patients came to the dental clinic for restorative treatment in order to rehabilitate the worn anterior dentition. Clinical analysis showed tooth surface loss located at the incisal edges by attrition due to an inadequate anterior guidance. In both cases the occlusal vertical dimension was reduced. First, following Dahl’s principle, resin attachments were placed in the upper canines. These attachments allowed the extrusion of posterior teeth in order to increase the occlusal vertical dimension. Furthermore, anterior teeth were intruded in order to create space for the restorative material. In the second phase, the restorative treatment was completed. Due to the characteristics of the case, feldspathic ceramic veneers were indicated. A diagnostic wax-up was performed to assist the treatment planning and a mock-up was prepared. Then, maxillary incisors were prepared through the mock-up to ensure a minimally invasive technique. Afterwards, silicone impressions were taken. Finally, veneers were cemented with a light-cured cement. In the present case, the functional and aesthetic parameters required by the patients were achieved, thus satisfying their needs. Key words:Tooth wear, anterior guidance, feldspathic veneers, Dahl’s principle, minimally invasive.
Highlights
Tooth wear is defined as the loss of tooth substance in the absence of caries and plaque
Tooth surface loss can present in various clinical forms with a wide range of etiological factors [2]
Occlusal wear of teeth due to attrition is the result of friction by functional and parafunctional activities
Summary
Tooth wear is defined as the loss of tooth substance in the absence of caries and plaque It is a normal physiological process and occurs throughout life but is considered pathological when the degree of destruction is excessive or the rate of loss is rapid, causing functional, aesthetic or sensitivity problems [1]. In recent years, there has been an increasing trend towards the restoration of worn dentitions using more conservative approaches with adhesive restorative materials, such as direct composite restorations or veneers [3,4,5] These approaches aim to preserve as much remaining tooth structure as possible [2,3,4,5,6]. The aim of this article is to describe an alternative treatment modality to rehabilitate the anterior guidance by a minimally invasive interdisciplinary ortho-restorative treatment
