An evaluation of 50 years of reconstructive dentistry. Part I: Jaw relations and occlusion.

Many concepts and theories have been propounded to enhance reconstruction of the dentition. Some have been put to practice; others have been rejected. All reconstructive procedures must be acceptable to the TMJ, the neuromuscular complex, and the periodontium. A correct centric relation and vertical dimension are critical to success. A major objective is to provide adequate function. The concept of occlusion and related articulation seems to play a secondary role. The best result occurs when the patient is unaware of the oral cavity and enjoys the esthetic result. A usable articulator should accept the face-bow and wax interocclusal records as well as provide for adjustable condyle paths, incisal tale, and a form of Bennett movement. Once adjusted, it should retain the position.
