Aesthetic and adhesive cementation for contemporary porcelain crowns.

The evolution of aesthetic restorative materials has led to the development of new preparation designs and cementation protocols. While conventional cements were able to provide mechanical and macromechanical retention for restorations with limited aesthetic expectations, resin cements with micromechanical retention have been formulated as aesthetic alternatives. The objective of the present article is to establish the differences between conventional and adhesive crown cementation techniques, as well as to provide guidelines for reducing postoperative sensitivity and improving aesthetic and functional results.

Aesthetic soft tissue integration and optimized emergence profile: provisionalization and customized impression coping.

In the anterior region, the successful replacement of a single tooth with an implant-supported restoration is one of the most difficult treatment options due to numerous functional and biological requisites. Such prostheses should also satisfy the increasing aesthetic demands of patients who expect the definitive restoration to mimic the natural dentition and their supporting gingival tissues. This article highlights the importance of the provisional restoration as the critical element for aesthetic success and gingival integration. Its perfect replication in the definitive restoration requires the use of optimized transference techniques.

Versatility and aesthetics of the IPS Empress all-ceramic system.

With the reestablishment of function no longer a clinical issue, the aesthetic challenge takes precedence, with patients expecting natural-looking results. Since the late 1980s, a leucite-reinforced pressed-glass ceramic (IPS Empress, Ivoclar Williams, Amherst, NY) has been utilized in the anterior region for full crowns and veneers and in the posterior region for crowns, inlays and onlays. This article presents results achieved with the IPS Empress all-ceramic system, which features a unique combination of strength and natural light transmission qualities that resemble the characteristics of natural teeth.

The evolution of aesthetic restorative materials for inlays and onlays: a review.

Composite and ceramic restorations are well-accepted treatment modalities for anterior as well as posterior regions, and numerous systems are available. This article presents the historical development of tooth-colored restorations from their incipience in 1882 to the second generation laboratory composites of today. The causes of failures in the early ceramics are discussed, and the search to delineate the optimal qualities of ceramics is outlined, listing the improvements of each new generation. The inherent obstacle of ceramic brittleness is reviewed along with the specific requirements of preparation. The learning objective of this article is to present the development of tooth-colored restorations in a concise form and indicate the characteristics of the materials currently available.

Custom-guided tissue healing for improved aesthetics in implant-supported restorations.

Implant dentistry and the latest generation adhesive restorations have been dramatic innovations in dental treatment. In addition to function, aesthetics has emerged as an indispensable prerequisite in the acceptance of the final result, demanded by the patient and the standards of excellence in prosthetic restorations. When replacing a single tooth in the anterior region, this prerequisite presents a particular challenge. The types of implant and healing abutment utilised influence the aesthetics which can be achieved. This article suggests a modification in the sequence of treatment planning, placing the temporary restoration at the second stage. This "custom-guided" tissue healing, along with the incorporation of anatomically shaped components, serves to achieve natural aesthetics in hard and soft tissues.

A pin-assisted retention technique for resin-bonded restorations.

The value of pins for auxiliary retention has been demonstrated many times. The use of pins with resin-bonded restorations allows for improved aesthetics and less tooth reduction while increasing resistance to dislodging forces. Clinical and technical procedures for resin-bonded bridges with pin-assisted retention are presented.

[Ceramic bonded veneers. Toward a minimal prosthesis].

For years, odontology for aesthetic purposes meant significant tissue mutilation. Now, with bonded porcelain veneers, it is possible to achieve both an aesthetic result and a veneer preparation while restoring the function of anterior teeth. The clinical forms of such thin bonded restorations may vary considerably, from a simple veneer to a 3/4 crown. Although after five years of experience, prosthetic "enamelling" appears to be totally reliable, only long-term clinical results will determine the fatigue of thinly applied ceramics.
