Abstract
A novel procedure for symmetric and consistent layer thickness management in esthetic direct restoration of anterior teeth is presented. For the purpose of obtaining a satisfactory final outcome of an esthetic direct restoration, it is crucial to standardize either margin preparation design and dentin and enamel layer thickness. Leaving too much space for the final translucent layer may lead in fact to “low value—gray” restorations if not correctly managed. The most common tool used to check layer thickness is the sagittal silicone index, which is reliable but involves planning; therefore, it requires two stages appointments. In this clinical case, a novel procedure is used to prepare, to model and to check thickness of composite shades in a single appointment, thus providing a symmetric esthetic outcome. A healthy 21-year-old woman referred to our dental office for the esthetic rehabilitation of both maxillary central incisors. The correct composite bilateral and symmetric layer thickness management provided a predictable esthetic outcome of the restorations. The main objective of this case presentation is to describe a novel technique that is able to save chair-time and dental laboratory costs during direct restorations in anterior teeth.
Highlights
Human beings, are bilaterians [1], they have a bilateral symmetry [2] with respect to the sagittal plane
Bilateral symmetry find in the two maxillary central incisors one of its highest expressions. Since these teeth are the most important part of a smile, every clinician should take particular care to the following aspects related to symmetry:
Symmetry and physical attractiveness is strictly related [3]; Central incisors are often very symmetric, while other teeth, like lateral incisors, may present huge asymmetries [4,5]; Central incisors’ asymmetries rarely exceed 0.2 to 0.3 mm in one of the three dimensions [6,7]; In an appealing smile, symmetry is very relevant near the mid-line
Summary
Human beings, are bilaterians [1], they have a bilateral symmetry [2] with respect to the sagittal plane. Some asymmetries can appear pleasant only if far away from it [8] For all these reasons, clinicians shall try to keep central incisors as symmetric as possible during the restorative procedures. Because ofno the young age ofbecause the patient, a noninvasive treat sound tissue, no post was planned for the left central incisor [10,11]. Alyzed the smile-line of the patient (Figure 3), silicone impressio yether material (Impregum Penta + Permadyne Penta L, 3M Esp order to develop a diagnostic wax-up (Figures 4 and 5) [12]. Used to reproduce symmetrically both maxillary incisors (Figure 9) Figure selection of both sound tissuetissue and previous restoration.
