  • Objectives: The quadrant theorem is a theorem proposed by C. M. Guzay in the field of functional, holistic dentistry. There are not much of scientific literature on the quadrant theorem. This study briefly reviewed basic concepts of quadrant theorem. Methods: A publication by Guzay and research articles were searched and reviewed. The quadrant theorem is depicted as a series of illustrations and accompanied explanations. Results: The primary concept of the quadrant theorem was presented in 1952. Based on geometric biophysics of the occlusion and related anatomical functions, physiological pivotal axis of the mandible is analyzed to occurs at the dens (the sub-atlas area). Composite muscular activity links the mandibular posture with C1-C2, which is then linked with the spinal posture. Twenty illustrations are progressively presented on the physiognomy, occlusion, and analysis of anatomical functions. The balanced distribution of the forces gives the durability of the functions in life. Conclusions: The quadrant theorem provides a functional linkage between the mandibular posture and the upper cervical vertebrae.

  • This is the third series of article on dental occlusion and relationship to TMD and systemic symptoms. In this part of the series, it will overview the theory, treatment methods, criteria, their limitation of Chirodontics, Dental Distress Syndrome (DDS) and quadrant theorem(QT). Chirodontics has its root on Chiropractic and to maintain the 'healthy status' of TMJ with stable occlusion via dental treatment. Dental distress syndrome on the other hand believes that all the TMD has originated from reduced or collapse of posterior support and incorrect posterior vertical support had caused imbalance of the head and neck structure which eventually affect the whole body symptoms. The analysis and treatment is planned using quadrant theorem where the position of head, rotatory pivot point and occlusal plane is analyzed.

  • The relationship between dental occlusion to temporomandibular Joint (TMJ), systemic symptoms and health has been discussed and theoretical reasons have been the foundation for treatments performed by various areas of alternative treatments. It has been noted that there have been increase in the available methods and treatments for the general public regarding these areas of treatment modality. Korean Academy of Stomatognathic function and Occlusion have carried out literature review of five of those treatment theories available; they are Craniosacral mechanism, Osteopathy, Myodontics, Chirodontics, Dental distress syndrome and Quadrant theorem. Each of these modalities will be introduced and brief summary of their efficacy and efficiency will be discussed.

  • A growing interest in management and treatment for patients with temporomandibular disorder(TMD) by many health workers, including oriental medicine doctors, physical therapists as well as dentists, have been noted in South Korea. Some of these health workers claim correlation between dental occlusion, TMD, and systemic symptoms such as tinnitus, dizziness, neck pain, myalgia, low back pain, posture and many other systemic symptoms and many controversial treatments are being carried out on bases of theories and reasons with no strong scientific evidence. This article is a result of preliminary study by authors in gathering scientific data on few of these various treatment modalities for TMD using MEDLINE data, internet and tutorials given by those who are using these TMD treatment methods. The modalities that had been searched are as follows; (1) Craniosacral mechanism (2) Osteopathy (3) Myodontics (4) Chirodontics (5) Dental Distress Syndrome and Quadrant Theorem. An outline of those theories will be introduced, and the contents in detail for respective theory will be reported in the following articles.
