READ ABSTRACT Human dental anatomy has not changed significantly in hundreds of years. Dental students and students of dental laboratory technology learn human dental anatomy as fundamental to their didactic work. Yet, so often we see dental restorations that do not follow the accepted basic design criteria of natural teeth. A possible conclusion is that the information was correctly presented as a basic science, but not completely carried over into clinical practice. When visually essential aspects of dental anatomy and composition are not accurately incorporated into esthetic restorations, patients are not completely served, and practitioners may be frustrated as well. This article reviews four essential aspects of anterior dental morphology—anterior tooth width/length proportions, bilateral symmetry, incisal edges, and incisal embrasures—that often are not accurately incorporated into dental restorations, and positions them in an easy to remember format: opposites.

READ LEARNING OBJECTIVES

• recognize the impact of natural width/length proportions, bilateral symmetry, incisal edge display, and incisal embrasure form on the dental composition.
• use the tools of the “opposites” lessons to predictably fabricate maxillary and mandibular anterior teeth that present as natural replicas.
• gain greater insight into the significance of the observer’s perspective in esthetic dentistry and learn to harness its power.

READ ABSTRACT Technology that encompasses computed tomography, cone-beam computed tomography, and interactive software applications has slowly progressed and evolved into a necessary tool for diagnosis, treatment planning, and delivery of dental implant and associated restorative and surgical procedures. The integration of these innovative tools is helping to define new methods for appreciating anatomy, improving accuracy, and enhancing presurgical prosthetic planning to achieve true restorative-driven implant dentistry. This article will demonstrate how computed tomography combined with interactive virtual treatment-planning software applications can empower clinicians with enhanced diagnostic capabilities for implant receptor-site assessment, generating new paradigms that eventually may supersede older methods of presurgical planning for dental implant reconstruction.

READ LEARNING OBJECTIVES

• understand the enhanced diagnostic information gained from computed tomography/cone-beam computed tomography imaging technology.
• appreciate how interactive treatment planning software can be an effective tool for assessing patient anatomy.
• understand how to recognize the “zone” as defined by the Triangle of Bone and how to apply the associated decision tree.
• appreciate how this technology can aid clinicians in achieving true restorative-driven implant reconstruction.
