Effect of resin surface sealers on improvement of stain resistance for a composite provisional material.

BACKGROUND: Resistance to staining is desirable to maintain the esthetic appearance of a provisional material. A resin sealant may improve stain resistance. PURPOSE: Color changes of a resin composite provisional material were measured by reflection spectrophotometry after storage in three staining solutions and water to determine stain resistance when treated with three methacrylate or urethane dimethacrylate resin surface sealants and when left untreated. MATERIALS AND METHODS: Specimens of a resin composite provisional material received one of three resin sealants (Fortify Plus, Bisco, Inc., Schaumburg, IL; Jet Seal, Lang Dental Manfacturing, Wheeling, IL; Triad LC, Dentsply International, York, PA, USA) or no surface sealer and then were stored for 72 hours in one of four staining solutions (water [control], black coffee, cranberry juice, red wine). Color was measured by CIE L*a*b* on a reflection spectrophotometer (Color-Eye 7000, Macbeth Division, Kollmorgen Instruments, Newburgh, NY, USA) at baseline and after storage. Color change (deltaE*) was calculated and analyzed statistically by two-factor analysis of variance, with four solutions and four surface treatments as independent variables. RESULTS: deltaE* ranged from 0.7 to 1.7 in water, from 1.1 to 5.5 in cranberry juice, from 1.1 to 6.5 in black coffee, and from 1.5 to 3.9 in red wine. Statistically significant differences were observed (p < .05), with Fortify Plus showing increased staining (deltaE* > 3.3) and Jet Seal and Triad LC showing decreased staining (deltaE* < 2.0) in cranberry juice and coffee compared with staining of the unsealed specimens. Only Jet Seal provided resistance to staining in red wine. CONCLUSIONS: Specimens without a surface sealer had statistically higher (p < .05) and perceptible or nearly perceptible color changes in cranberry juice, black coffee, and red wine than in water. Specimens coated with Jet Seal had statistically lower (p < .05) color changes than uncoated specimens in cranberry juice, black coffee, and red wine. When coated, the color changes of the stained specimens were not perceptible. Specimens coated with Triad LC had statistically lower (p < .05) color changes than unsealed specimens in cranberry juice and black coffee. When sealed, the color changes of the specimens stained with cranberry juice and black coffee were not perceptible. Both unsealed and sealed specimens stained with red wine were nearly perceptible. Specimens coated with Fortify Plus had statistically higher (p < .05) color changes than uncoated specimens in cranberry juice and black coffee but statistically the same (p < .05) color change as uncoated specimens in red wine. These specimens had perceptible color changes in cranberry juice, black coffee, and red wine. CLINICAL SIGNIFICANCE: Surface of methacrylate or dimethacrylate resins can improve resistance of a resin composite provisional material to staining caused by cranberry juice, black coffee, and red wine.

[A case of interdental papillae growth by application of maxillary anterior crowns].

PATIENT: The patient had esthetically unacceptable maxillary anterior crowns. Provisional restorations in consideration of the smile line were used for the maturation of periodontal tissues. Owing to full regeneration of interdental papillae, small black triangles that existed in the gingival embrasure disappeared six months after the luting of final restorations. DISCUSSION: We should not overlook the importance of physiological occlusion for the management of healthy periodontal tissues. CONCLUSION: To create a natural-looking esthetic prosthesis, the dentist should strive to create an ideal environment for the technician to fabricate functional and esthetic restorations.

Predictable periimplant gingival esthetics: use of the natural tooth as a provisional following implant placement.

UNLABELLED: Maintaining the interdental papilla and bone height following implant placement has been a challenge for the restorative dentist. Bone resorption following anterior tooth extraction is common and often compromises the esthetics of the final restoration. The tissue must be maintained during the surgical and healing phases to achieve an esthetic outcome. Using the patient's natural tooth as a provisional can help maintain the volume and support the papilla. This article describes a technique to achieve maximum esthetics and preservation of tissue following tooth extraction and implant placement. CLINICAL SIGNIFICANCE: By using the patient's extracted natural tooth, the tissue should maintain itself with minimal recession. This will allow for a more esthetic outcome.

Prosthetic procedures for optimal aesthetics in single-tooth implant restorations: a case report.

Restoration of a single-tooth implant in the anterior maxilla requires a multidisciplinary approach throughout the treatment and proper communication between the clinician and laboratory technician. Although surgical procedures have an important role in the manipulation of the soft tissues, it is often necessary to perform final contouring of the soft tissue through the provisionalization stage. Unless the soft tissue contour supports the definitive restoration, the treatment is considered a failure. This article reviews various prosthetic procedures that influence the soft tissue contour and establish aesthetics for implant-supported restorations.

Achieving aesthetic excellence through an outcome-based restorative treatment rationale.

The conceptual basis of restorative-driven implant dentistry is well established among clinicians. Its implementation includes the development of a prosthetic blue-print that will serve as a guide throughout therapy. While these concepts may be applied to prosthetic dentistry in general, their benefits are most compelling in the treatment of the aesthetic zone. This article demonstrates a systematic multidimensional approach for the establishment and incorporation of definitive aesthetic objectives throughout the diagnostic, adjunctive, and restorative treatment phases.

Flapless anterior implant surgery: a surgical and prosthodontic rationale.

Full-thickness periosteal flap surgery is often accompanied by potential marginal bone loss and/or soft tissue recession. This is critical, particularly for the single-unit implant-supported restoration in the anterior maxilla, where the harmony of the soft and hard tissue architecture is of paramount importance to the development of natural aesthetics and function. This article demonstrates a flapless implant surgery technique in the anterior maxilla for optimal aesthetic results. The indications and limitations of this procedure are also discussed.

The management of gingival and esthetic problems: a clinical case.

The coordinated management of gingival and esthetic problems is important in dentistry. In addition, the most difficult variable to control in the treatment of anterior esthetics is the soft tissue. This article discusses the relationship between the surrounding soft tissue and the emerging crown form. The authors introduce a soft-tissue index model technique that will help the technician in fabricating the final crown with a form similar to the provisional. In this case report, provisional crowns are fabricated with enough tissue support to provide for an optimal crown-gingival interface. The present case demonstrates how to manage the gingival margin in the provisional stage and how to transfer the provisional and soft tissue to the laboratory model.

Success with inlays/onlays: the seven essentials.

Direct restorative materials have revolutionized the industry over the last several years. They offer the convenience to the patient of a one-visit procedure and they decrease overhead in the dental practice. However, it is essential to remember that direct procedures are not always the treatment of choice. For this reason, we should not discount the need for--or the value of--indirect techniques and laboratory-based procedures, such as inlays and onlays. Fit, form, and function can be more predictable when a procedure involves the ultraprecise workings of the dental laboratory--if the impression-making and other focus areas are given their due significance. This article provides key information about and clinical tips for the seven main facets of inlay/onlay fabrications that will lead to clinical success: diagnosis, tooth preparation, tissue management, impression making, temporization, laboratory communications, and final fit/occlusion.

Controlled orthodontic extrusion to create gingival papilla: a case report.

Prosthetic dental restorations alone do not produce esthetics. They must be in harmony with the surrounding gingiva, especially the gingival papilla. This case report describes the enhancement of the gingival papilla between an implant replacing the maxillary left central incisor and a provisional crown on the maxillary left lateral incisor. Esthetic harmony was disrupted by the absence of an interproximal papilla. First, provisional crowns on the implant and adjacent tooth were used in an attempt to remodel the interproximal gingival tissue, but the esthetic result was not satisfactory. The second attempt involved orthodontic extrusion of the lateral incisor in an incisal direction. The gingival tissue migrated incisally, thus restoring the deficient papilla and establishing restorative and gingival harmony. Both the implant and the lateral incisor were restored with ceramic crowns.

Aesthetic design preservation in multidisciplinary therapy: philosophy and clinical execution.

Complex perio-prosthetic cases that require multidisciplinary therapy often result in compromised aesthetics. Traditional treatment planning philosophies, as well as existing interdisciplinary relational patterns, do not promote the achievement of predictable aesthetic results. Implementation of a restorative-driven approach requires the development of an aesthetic blueprint that will serve as a guide through treatment. This article illustrates the clinical techniques and sequence for an outcome-based protocol that enhances therapeutic cohesiveness and ensures the sequential transfer of design objectives for the preservation of aesthetics in multidisciplinary therapy.
