Abstract
We dental technicians is not versatile at clinical by the dentist's instruction if neither the form, the row of teeth nor the engagement of teeth from an anatomy viewpoint that is basic to produce the mending device are understood. The purpose of this is to consider the functionality that appropriately harmonizes with an individual patient because various bite voice exists at the living body in clinical. However, it is perplexed though it doesn't know it only has to train the technology what being aimed because the basic model of ideal normal occlusion still along the anatomy that was able to be defi ned clearly doesn't exist. At that I made tooth carving that I refer to the average of individual japanese teeth and I try to arrangement and carry out inspection with searching the position that engaged most aiming to make a embody the normal occlusion model that was basic from an anatomy viewpoint that became an index to correspond to variety of clinical. As a result, the following were able to be confi rmed though it was rough. 1:The incisal embrasure showed the extension from the front to the side in a constant law. 2: As for the dental arch of occlusal view the maxillary second molar and mandible second molar tended to become the outside opening. 3: The occlusal surface of the sgide showed the curve of SPEE in same hight as which the adjoined near the marginal ridge. 4: The upper jaw molar tooth axis of the sagittal view tended to cause the mesial inclination. 5:At the maxillary fi rst molar of the sagittal view, distobuccal cusp was excel. 6: The maxillary fi rst molar of the sagittal view and the marginal ridge of the maxillary second molar especially, the difference attached. 7: It was not a relation of cusp to fossa though the opposing relation became one tooth to one tooth.
