Fundamental to the esthetic effect is the interplay between the proportions of the face, the contour of the mouth, the lips, and bite harmony. In order to capture this, the esthetic analysi is essential. Starting with the as-is situation, the target situation is defined. The target situation represents the goal of treatment and serves as the planning basis for all further steps. Prosthetic complications may manifest biologically, functionally, esthetically, or technically. Functional analysis aims to determine potential causes of functional complications and define a feasible occlusion and loading concept.
