Multidisciplinary dentistry in management of untreated Fluorosis in an adult using ceramic veneers. Malocclusion treated with Orthodontics and Bone Screws .
The patient was a healthy 22-year-old woman leaving this country to pursue her studies overseas soon. We were given less than 6 months to complete her case. Poor alignment and discolored were her chief complaints. The patient wanted a fuller, more attractive smile. The patient’s heightened awareness of her dental appearance led her to our practice in search of a conservative , digital smile makeover .
Proper case selection is critical in obtaining a natural result when treating the dentition with minimal-preparation veneers. Patients have long welcomed this concept of a long-lasting, minimally invasive procedure that favors the preservation of enamel. It cannot be overemphasized that case selection is critical in the application of this technique. This patient was initially thought to be a simple case but the lower jaw was protrusive and we need to bulk the upper anterior dentition, with no-preparation or minimal-preparation may have undesirable results. Upper teeth look too procline to compensate the lower jaw.
Since we tried to make this case as ideal as possible, orthodontics and bonescrews were required to give a good positive overjet and overbite in this case. The orthodontic treatment gave the position of teeth that were required her dentitions benefited from the minimal- preparation veneers except for the two centrals which had substantial caries were crowns . The rest could be treated in combination with shade change and incisal edge restoration.
Ceramic veneers are considered a conservative solution for patients requiring improvement of the shape, color, or position of their anterior teeth. Ceramic veneers have been extensively and successfully used to mask intrinsic staining, to give the appearance of straightening, and to correct minor malformations of anterior teeth without the removal of substantial amounts of sound tooth substance. There are several methods of attaining the reduction required with the preparation: freehand, use of depth cuts/grooves (the use of depth cutters or grooves and dimples has been recommended to control tooth preparation, as the use of standardized objects allows accurate judgment of depth), and use of silicone putty index or the provisional (use of a silicone index derived from the wax-up allows a visualization of the reduction required to achieve the form and contours of the preplanned shape and length of the final veneers).
Traditionally, composite has been the preferred treatment modality when thin restorative veneering was needed. But today, with the introduction of minimal-preparation veneers and crowns a longer-lasting and more durable result can be provided. Ceramic offers a virtually stain-free surface, permanent high luster and polish, and superior incisal edge strength, which is far greater than the microhybrid composite of today. Fabrication of crowns and veneers involves a laboratory procedure, offers more control than composite because the ceramist has several days to fabricate the restorations.
