With the advent of injected “leucite-reinforced” ceramics in the last century’s early 90’s1, something changed in how an indirect restoration was made; however, more than that, there was a change of behavior in a generation. A decade earlier, in the early 80’s, after the classic publications2,3 showing how the etching of porcelains favored the creation of a structural unit and adhered to the dental enamel, a movement was already beginning. The possibility of bonding a metal-free...
Abstract: Gingival lichen planus, lichenoid lesions and gingival pemphigoid are difficult to diagnose because they are confused with chronic inflammatory periodontal disease associated with dentobacterial plaque, especially when there is painful sensitivity that makes oral hygiene difficult. The patient searches, successively, several professionals, in search of a definitive solution. There has to be confidence in the Gingival lichen planus diagnosis and control because it is an autoimmune...
The pattern of dental esthetics has changed. I mean, it has already changed. Not that it is the beginning of a movement or a trend that points to changes, not really. We are receiving in our offices patients who ask for a new esthetic; the beautiful of today is another, very different from the beautiful of a short time ago. What happened?
We started our fourth column of JCDR (third of 2017) with an article that reports a clinical case that deserves reflection. We have published, in other articles, several cases showing our conception and clinical approach in different cases, such as the indication of composite resins in a young patient, mainly in orthodontic finishing, laminates of the ceramic contact lens type with sufficiently invasive preparations, the right moment for the transition from resins to ceramics and, in the...
Abstract: Nowadays, aesthetic requirements of our patients are very high. This is encouraged by media consumption, in which models with perfect white smiles are shown to the public as references of beauty. In cases in which biological reconstruction is no longer possible, in order to achieve a result of excellence, it is necessary to create interdisciplinary alternatives that can solve the treatments. Therefore, the technological evolution guided by scientific researches has brought to...
The fourth “International Symposium on Light Sources in Dentistry” was held at the Dalhousie University School of Dentistry, Halifax, Nova Scotia, Canada, from 4 to 5 November 2016. The organizer of the four editions of this event was Professor and Researcher Dr. Richard Price, who invited approximately 50 participants from different countries. Among the participants, important names that act on the subject, among researchers, clinicians and manufacturers of light curing-equipment were...
Abstract: The aim of this study was to evaluate in vitro the implant-abutment interface misfitting of external hex UCLA abutments used for full-arch implant-supported prostheses, using scanning electron microscopy (SEM). Six aluminium models were used, which were divided into two groups: a) MINI (1-mm mini-abutments); and b) UCLA (UCLA abutments that were fused with a prosthetic bar). The MINI group was used as control. After applying the torque recommended by the manufacturer, the...
Abstract: The immediate implant placement and provisionalization (IIPP) is associated with vestibular recession and decrease or loss of buccal bone plate, in most case series. The search for biomaterials and clinical protocols that minimize this problem is the focus of most current research, but still with no resolution. Thus, the aim of this literature review was to study the behavior of hard and soft peri-implantar tissue in IIPP which used biomaterials and autogenous bone as bone graft...
Abstract: Gingival smile can be defined as a gingival exposure greater than 3 mm of the area located in the cervical third of teeth. The literature reports that its etiology can be isolated or attributed to an association of factors. Among such causes, can be listed: skeletal aspects such as dentoalveolar extrusion and vertical maxillary growth; and even aspects related to hyperactivity of the upper lip levator muscle. Methods: in the present clinical case, gingival smile was diagnosed due...
Abstract: Tooth preparation, when necessary, is one of the most important considerations in the fabrication of porcelain laminate veneers. Bonding to enamel provides strongest bond values when compared to dentin. This way, the focus on tooth preparation is to be conservative in the reduction of sound tooth structure, aiming longevity. At least two different strategies for tooth preparation can be found in the literature. Simplified protocols included the use of depth cutters guided by the...
Abstract: Severe tooth wear treatments demand minimally invasive restorative procedures. The aim of this article was to present and discuss a clinical case of an oral rehabilitation with occlusal vertical dimension (OVD) management and adhesive procedures achieving satisfactory aesthetics and adequate stomatognathic function. Provisional OVD augmentation with composites, anterior “full veneers” and posterior partial restorations were utilized. Comprehensive planning and the correct...
