of functional loading. This occurrence is validated in the intact teeth of older adults, particularly upon trans-illuminated views. (FIG 7.) Lacking awareness of this structurally advantageous non-uniform distribution of enamel/dentin, gives rise to optical integration nuances, frequently puzzling the restorative team due to the fact that traditional dental morphology curriculums focus primarily on external enamel surface characteristics, oversimplifying the subsurface union with dentin, thus assuming uniform distribution. Hence visual correlations between the enamel/dentin elements is deemed of significant value. (Table 1.) Stone replicas (Pearl White, GC Fuji Rock EP, Alsip, IL) were made in order to establish inter- relationships and better assess surface topography and characteristics. (FIG 8.)
DISCUSSION:
The purpose of this endeavor is to facilitate dental clinicians and technicians and students in these disciplines, in the proper visualization and sound understanding of spatial ordering amongst the enamel and dentin structural elements. Once this is mastered, reconstruction of the dentition takes on a proficient and predictable manner. Provided the fact that the divine design of the intact tooth is unrivaled on a micro-structural level, one must be inspired to endeavor towards the macro-structural emulation with the current bio-materials at hand. Armed with this knowledge of the Bio-Emulation model, commencing direct and indirect adhesive dental restorations take on a refined and intuitive manner, rather than an over-simplified automated one. The refinement we mean is not that of simplification, yet one that thrives on thorough understanding of the innate structural complexity of the intact tooth; it relies on powerful yet efficient spatial ordering principles of the analogous dental structures.
