feldspar and Dental-Caries

A differential diagnosis of excessive gingival display is critical in determining appropriate treatment options and sequence. Anterior tooth malposition for patients with deep vertical overlap has been suggested as one of the 3 main causes of excessive gingival display. Specifically, patients with Angle class II, division 2 malocclusions show an occlusal scheme that might be responsible for additional anterior tooth wear when compared with individuals without malocclusion. In the long term, this condition can cause dentoalveolar compensation and overeruption of maxillary incisors with concomitant coronal movement of the gingival margin with excessive gingival display. A combined orthodontic and restorative treatment was proposed as a conservative treatment to reposition maxillary anterior teeth and their gingival margins to a more ideal position and create the necessary interocclusal restorative space to restore worn teeth with ceramic restorations, enhance dental and facial esthetics, and reestablish anterior guidance.

This article describes a multidisciplinary approach to a functional and aesthetic rehabilitation. In this case study, we successfully corrected an anterior open bite and an exaggerated curve of Spee using restorative modalities while still maintaining a highly aesthetic outcome. The maxillary anterior teeth no longer appear to have a disproportional width/length ratio and are now in harmony with the mandibular veneers. Posterior function was re-established, mostly with implant-retained crowns. Occlusal harmony and stability are maintained through cuspid guidance and anterior disclusion. Proper selection of final restorative materials is imperative for the long-term survival of the restorations.

Ceramic inlays offer a good alternative to posterior composites, which still show a high polymerization shrinkage. The thin cement layer will reduce the total amount of shrinkage and probably result in a better marginal adaptation and decreased marginal leakage. Fired feldspathic ceramic inlays cemented with either a glass ionomer cement or a dual-cured composite resin luting cement were compared intraindividually. During a 3-year period 118 inlays, 59 in each group, were examined. Eleven inlays were evaluated as non-acceptable during the period: two (3.4%) in the composite resin group and nine (15.3%) in the glass ionomer cement group. In the composite group one inlay fractured partially and one inlay was replaced because of postoperative sensitivity. In the glass ionomer group four inlays were totally lost, and partial fractures occurred in five inlays. In the fractured glass ionomer cemented inlays the cement was still in place in the cavities. Eight patients reported post-operative sensitivity. No secondary caries was detected around the inlays even though 46% of the patients were considered high caries risk patients.
