The search for a standard light-curing protocol.

The selection of a curing light protocol is a multifactorial decision that will undoubtedly provide thought-provoking debate in the near future. While each method of polymerization presents unique clinical benefits, the optimal light-curing technique remains to be determined.

Functional versus aesthetic articulation of maxillary anterior restorations.

The correct orientation of the master model is a frequently overlooked aspect of communication between the clinician and the ceramist. The master model must provide the ceramist with the same perspective of the patient as is seen by the clinician--facing the viewer. Unless precise information is transferred to the laboratory, the ceramist can only estimate horizontal and vertical alignment of the working cast from landmarks taken from the cast itself. It is unwise to leave such appraisal to chance, especially when restoring multiple anterior preparations, where the potential for misalignment of the cast increases with the number of restorations involved. The learning objective of this article is to discuss communication techniques between the clinician and the ceramist for achieving precise and predictable orientation in the treatment of aesthetic anterior restorations.

Smile rejuvenation: a methodic approach.

The innovations in dental restoration materials during the last decade have enabled the clinician to achieve improved aesthetic results. However, dependence on the materials alone does not necessarily produce predictable aesthetic results. As the learning objective, the author discusses the need for a methodic approach, the observation of the intact smile, the dominant position of the maxillary central incisors, and the art of aesthetic integration of the maxillary incisors in proper proportion with the face and stature, thereby producing pleasing sensations in the observer.

[Morphology of implant restorations in the cuspid area].

Implant supported posterior restorations must be constructed following established prosthetic principles. The need for screw-retained abutments and the narrow diameter of root form implants dictate additional treatment protocols that fail beyond the scope of conventional prosthetics. Cemented restorations offer simplicity and good control of morphology, but can only be considered if no reservicing and removal of the restoration are anticipated. Screw retained restorations allow for reservicing on remediation but necessitate centering of the fastening screw within the occlusal anatomy. In case of implant misalignment, axis problems are solved with preangled or customized copings, or double frameworks. The diameter of root form implants is significantly smaller than posterior natural teeth and the emergence of the restorations must be progressively flared to achieve proper anatomy. Limited interocclusal space and implant placement may dictate restoring posterior teeth as premolars selecting a short abutment or a UCLA abutment, or overlapping the crowns over the soft tissues. The final selection is best assisted with a diagnostic waxing and with provisional restorations anticipating the completed treatment.

Implant surgical template for partially edentulous patients.

A stable and dimensionally accurate surgical template provides a precise and stable reference for implant placement in the partially edentulous patient. Implant location and axis can be rigidly controlled with calibrated channels incorporated into the template.

Laminated single impression technique for cast posts and cores.

A laminated single impression technique for cast post and core has been described. Its advantages are the ease and versatility with prefabricated or customized post techniques (Fig. 14) and the one-step registration of single or multiple divergent canals. Its disadvantage is the necessity for additional laboratory procedures.
