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.

Recently, all-ceramic restoration, representive for zirconia, has been focused based on the development of CAD/CAM technique and its biocompatibility. However, the application of all ceramic restoration was limited to single tooth originally, and it was diffi cult to use it for full-mouth reconstruction by its physical properties for the cases in which both tooth and implant exist. In this study, we considered how we use all-ceramic restoration for full-mouth reconstruction through some cases in which both teeth and implants exist. We concluded that adequate selection of application, laboratory techniques based on understanding the property of materials, correct clinical processes in the determination of relationship of maxilla and mandibullar and the management of the changes of occulusion are crucial for all-ceramic restoration.

Several bone augmentation techniques have been developed to enlarge implant recipient sites in the cases that the bone mass was insuffi cient to place implants. They could accomplish adequate implant placement and also offer good esthetical outcomes as a result. Of them, cortical bone block graft using autologous bone is reported to increase bone width over the wide area especially in the severely resorbed anterior maxillary region, and to bring a good clinical outcome. However, there are few reports concerning detailed evaluation of grafted bone in the long-term observation. In this case, the cortical bone block graft from the mandibular symphysis as a donor site was applied to atrophic anterior maxillary region for implant restoration, and we had a good outcome for a long period. In addition, we evaluated the situation of the grafted bone around implants by cone beam CT after implant treatment for 7 years, and we could confi rm the steadiness of grafted bone. We concluded that bone augmentation using cortical bone block graft was useful for implant treatment at severely atrophic anterior maxilla region, and might bring a stable result. Furthermore, the steadiness of grafted bone around implants in the long-term observation was confi rmed by using cone-beam CT.

Nowadays implant treatment is expected to provide the suffi cient outcomes both in esthetical and functional aspects within a shortened healing period. We have experienced a 59-year female patient because of a long distance resident from our offi ce who demanded the fewer treatment time In order to meet the demand prior to the treatment we decided to use the conventional full denture on the maxilla Regarding to the mandible we planned to perform the simultaneous implant installation at the time of teeth extraction and immediate loading. In a usual method differences of the implant position which were from pretreatment planning caused us diffi cult to get the satisfi ed esthetical outcomes And now application of a surgical template fabricated by NobelGuide enabled us to install implants precisely matched to the predesigned positions then immediate loading Furthermore precise implants positioning provided excellent laboratory work which lead to the highly esthetical prosthodontic outcome. This method such as guided surgery not only minimized the surgical stress and treatment period but also provided the remarkable esthetical and functional outcomes.

What is the best state of balance of teeth (periodontal tissues) and TMJ? To answer this question, at fi rst, the mandible position, which is harmonized with the living body, needs to be determined with many data, such as the facial photographs, the oral cavity photographs, study cast analysis, cephalogram analysis, and TMJ functional movement examination. Then, reconstruction of the occlusal pattern is reflected in order to make that TMJ movement smooth. When we make the full-mouth reconstruction, we consider that the best balance of the upper and lower teeth contact, and the best TMJ position and movement need to be obtained in the oral cavity. Here, the diagnosis and technology are reported.
