This paper investigates the functions and biomechanical properites of the viscerocranium from the perspective of phylogenic evolution. A new concept of the mechanical skeletal masticatory apparatus is proposed. Combines trilateral research in morphology (phylogeny-ontogeny), molecular genetics, and biomechanics, was reviewed in order to answer the question“What is the viscerocranium, i. e. face ?” For this purpose consideration of the basic construction of vertebrates and evolution in vertebrate was studied. For an insight into the basic skeletal construction in the viscerocranium, especially in the masticatory structure, the biological and biomechanical properties of the tooth were also investigated.Establishment of basic construction of the vertebrates was carried out during neoteny (larval form evolution) of the hemicordata, which integrated the respiration, nutrients, and excretion system into only one tube of the gut. Through evolution of the vertebrate, mammals evolved after four kinds of vertebrate-revolution. These evolutional phenomena can be seen as revolutionary transformation of morphology in biomechanical responses to environmental changes. Through these evolutional transitions, various kinds of concerns develop between morphology and the function of organs in the human body from the standpoint of basement construction of the vertebrates. Through this study immune system was studied and a new concept for immunology as cytological digestion system was also proposed.

In the case of maxillary protrusion, the bone resorption of maxillary alveolar bone is not observed after tooth extraction. In this case report, a denture base of the anterior shape in the maxillary denture was made the none denture base form to improve a protrusive feeling of a maxillary denture. And the magnetic attachment was used to stability of overdenture. As a result, it was provided clinically good condition in esthetic and functional.

I have already discussed my opinions on how occlusal disturbances affect people's lives. Delivery using forceps may cause abnormalities in the temporomandibular joint, and the pressure from a twin's buttocks while in the womb may make the sibling's head rhomboid in shape, disturbing its symmetry. These people often have“hearts”and“bodies”which are nervous and sensitive. Marital problems promote thumb sucking resulting in an open bite and stiff neck in children, as well as making them susceptible to children's diseases. The problems of missing teeth become worse with age leading to dentures, proceeding to stiff necks, headaches, hip pain, numbness in the extremities, heart disease, high blood pressure, and senility, with life ending in a early, unhappy death. Dentists will have a very bright future when we contribute to people's health through their teeth, give them a prosperous and happy life, become needed by all, as well as being loved and respected.

The Bi-Digital O-ring test is a diagnostic method in which the patient's physical condition is judged by his/her finger stregth. The patient is made to form a Bi-Digital ring using the thumb and any other finger on the same hand. The doctor then forms two of the same rings with his/her own hands, interlocking them with the patient's ring and then, While the patient using his own finger strength resists, the doctor attempts to pull open the ring from both sides using his own bi-digital o-rings. Diagnosis is made based on the patient's ability to maintain closure of the ring.We apply this test to make diagnosis in the areas of conservative dentistry, prosthetic dentistry and oral surgery. It is a very useful method for occlusal diagnosis, determination of mandibular position and teatment and diagnosis of temporomandibular joint porblems. We would like to report on our objective observations and clinical cases.
