Establishing ideal occlusion to achieve esthetic and functional excellence: an interdisciplinary approach to functional esthetics.

When diagnosing and treating occlusal problems, a thorough evaluation of occlusal planes is essential. Studies have shown internal derangement may cause minimal morphologic changes in one patient. In another patient, severe condylar changes with the same level of internal derangement severity may occur. The factors may include contraceptive use and systemic conditions, such as arthritis. The following two case reports feature females who presented with nonfunctional open bite malocclusions, displaying distorted curve of Wilson and curve of Spee with minimal tooth contacts and histories of temporomandibular joints symptoms of varying degrees.
