Enhanced resilience and esthetics in a Class IV restoration.
The purpose of this article is to give the reader a better understanding of the complex restorative challenge in achieving true harmonization of the primary parameters in esthetics (i.e., color, shape, and texture) represented by the replacement of a single anterior tooth. The case presented demonstrates the restoration of a Class IV fracture taking esthetic consideration of the anatomic variations of the adjacent teeth to produce a direct composite resin in harmony with the surrounding dentition. The basic procedure includes tooth preparation, development of the body layer, internal characterization with tints, development of the artificial enamel layers, shaping and contouring, and polishing. In understanding the total morphology of a tooth and using natural teeth as the basis for morphological thinking, the clinician possesses the knowledge to create restorations with a more natural appearance. Use of a recently developed optimized-particle composite and this morphological thinking allowed the author to achieve a restoration in harmony with the surrounding dentition. Continuing technological breakthroughs allow the clinician to implement and maximize new products to attain more predictable and esthetic results as demonstrated by this methodological protocol of incremental application of composite resins and modifiers to transform the Class IV fracture into a final restoration that mimics nature.
