    Recently, implant treatment has become common. We must consider how to let implant prostheses be stable for long : ion dissolution may take place, because metal used for implants is different from the superstructure. To settle this problem, you can use the same metal as the implant for the superstructure, or use no metal. We introduce the superstructure made of pure titanium or the glass fiber frame in these cases. These cases are doing well after treatment.

    Although electric, ultrasonic and acoustic toothbrushes are now becoming available in shops, the effects and functions of those toothbrushes are not fully understood and consumer information is limited. Therefore, in order to improve the efficiency of plaque control, we examined and compared the characters, functions and effects of one hand toothbrush, two types of electric toothbrushes, one ultrasonic toothbrush and three types of acoustic toothbrushes.
    As a result, it showed that each type of toothbrush has its own characteristic features which affects its degree of efficiency in removing plaque. This shows that the training in the use of acoustic toothbrushes is needed, as well as the training with hand toothbrushes.

    Two sorts of un-absorption barrier membrane are currently used in GBR around a dental implant. They show different clinical outcome though they are made from the same ingredient. The one is popular and has high reliability. But many clinicians have worry about the exposure of barrier membrane. The other tends to keep off the exposure, which covers the disadvantage of the one. Why do two kinds of barrier membrane have different clinical result, which are consisted of the same polytetrafluoroethylene (PTFE) ? Tow sorts of PTFE. e-PTFE and n-PTFE, are observed by the electron microscope to find the difference in their structure. Consequently, we confirm a clear difference in their structure between them, which explain scientifically the difference in a clinical condition between two sorts of PTFE.

    Dentistry has been developed with the benefit of general science, especially medical science and biology, and changed the basic concepts of dental treatment. Endodontology can contribute to comprehensive clinical and basic research areas in which other studies including periodontology, oral surgery, operative dentistry, pedodontics and prosthodontics are also related. However, from the standpoint of evidence-based dentistry, development of Endodontology is not so fruit except root canal preparation and obturation technology. Then we will introduce multidisciplinary study areas and discuss the future direction in which Endodontology will be involved.

    In the 1920s, electric scalpel was developed by W.T.Bovie. From then on it is indispensable to medical Surgery for 90 years. Now we applied new type electric scalpel to dental treatment and locate (call) it high frequency treatment. Applying the weak current, narrow point causes the highest heat by electrical resistance ; the other point diffuses electrical current. Then we can use it safely in a way that turn on high-frequency current of clotted wave pattern fitfully to teeth and gingival. I report using this Joule heat is useful to pulpectomy and root casual treatment and periodontal treatment.

    To control the occlusal force, we emphasized the importance of actual mandibular movement of the habitual first stroke of mastication in our previous study. From the viewpoint of the actual mandibular movement, it is very important to clarify the mechanism of healthy stomatognathic system.
    In this study, some clinical markers of the mandibular movement were investigated to compare the etiology of the clinical symptoms in the patients with intact dentition, The results indicated that sliding movement had the most important co-relation with the clinical symptoms, while canine guidance, anterior guidance or tooth crowding had not. As it is well known, the force to the retrosuperior direction for the stomatognathic system is destructive for the stomatognathic system. It is cleared that making use of the mandible with side movement, not with hinge movement is utmost important to exclude this retro-superior force.

    It is difficult for the occlusal reconstruction of the groundless occlusal position, for example, not being the intercuspal position, or being questionable it. I think, in this case, it is necessary that it makes the appropriate intercuspal position on the basic of the appropriate mandibular position. It is necessary, say in other words, the establishment ofthe occlusal position on the basis of it of condylar and mucle position. But the mandibular position with the unphysiological condition extend over the long time is not appropriate always. Because it may be with the hypertension of muscles, or the strain of temporomandibular joint area. Usually we are not able to approach them direct. But we are able to guide the appropriate mandibular position with the relaxation of muscles related to masticatory movement, if we make temporary occlusal position and take advantage of the questionable it. I am sure that the occlusal splint, as the important part, is the indispensable mechanism for occlusal reconstruction.

    Each day, patients come into my office with their dental problems. When I studied gnathology several years ago, I treated patients with the use of articulators. But this procedure could not be implemented in all cases. There are several reasons for this.
    The primary reason is due to the difference between the patients' varied masticatory processes and the rigid function of the articulator. The movements of the mandible serve several functions such as; swallowing, pronunciation, and mastication. These movements of human being are different from the border jaw movement of the articulator. The masticatory movements are mostly related to the occlusal pattern.
    The second reason is due to the mandible position being affected by different personal habits (resting one's chin, sleeping on one side, chewing on one side, etc) and parafunction (mouth movements without purpose or conscious such as; grinding, clenching, tapping, tongue habit or lip habit.)
    The following case report describe the success of treatment caused by considering function and parafunction such as examinations, diagnosis and actual treatment. I regard these cases would have failed according to former principles of gnathology.

    It is being important when you understand occlusion is considering a 2-pair-of-shoes walk of human beings and the process of evolution of a life. because, probably malocclusion and the concept of TMD exist only in people, and they are unrelated to other animals. The meaning of this paper is to explain a 2-pair-of-shoes walk, cerebral growth, stress management, the distortion of the whole body that comes from malposition of the lower jaw from human existence. Furthermore, by considering a Japanese root in the second half, malocclusion and a frame pattern are considered and the state of occlusal is reconfirmed. I think that it changes into physiological gnathology and occlusion which took into consideration anthropology, and growth and adaptation of people for the first time from mechanism--by this gnathology.

    To examine the relationship between masticatory disability and mortality in a communityresiding elderly population, 1, 245. randomly selected people aged 65 years and older were following over 9 year period (398 deceased and 847 alive) . Data on health status as indicated by disability scores, history of health management, psychosocial conditions were collected at the time of enrollment. As for the association between masticatory disability and mortality, the estimated survival rate for those with masticatory disability was lower than that for those without for each group stratified by sex and age groups and the equality of survival curves according to masticatory disability was significant for each group. After controlling for potential predictors of mortality, masticatory disability remained as a significant predictor for mortality.

    POI 2 Piece Implant ®having been applied to the Implant therapy clinically since 1991 has hitherto raised a successful result for the young through old broadly.
    We herewith report this time of our clinically examination made for eldery patient having been kept under Implant therapy for a long period.
    The patient was an old man of 78 years old whose alveolar ridge was found absorbed remarkably, resulting in unfitness of full denture. So he wanted to receive the Implant therapy for him. He was treated of anterior mandible by inserting 4 of POI 2 Piece Implant ®32-14F in March, 1992. But I of 4 Implants had failed during healing period. Bioceram ®Implant had been inserted at the positions 32 and 42 each additionally. After the healing period had passed, the cement-fixing type of prosthesis had been loaded there. Although having been kept preferable of his condition for prognosis after setting prosthesis, he visited our dental office, chief complaint of pain in the base of cantilever on the both sides in 1998. Therefore, we removed the cantilever and set end-free denture. He visited our clinic again in April, 2002, appealing for him to become hard to remove the end-free denture on account of abnormal shrinking of the muscle of his right arm. As I also found his super structure unstable due to loosing of its straight post, I removed the super structure, repaired the used end-free denture by adding tooth thereto, and modified it into the overlay denture using the ball attachment on June 10, 2002. After setting new overlay denture to the patient October 5 2002, no such troubles as swelling and pain bade been eliminated completely, and the denture has been kept good stably since then, keeping good condition.
    As shown above in a case, I think it would be necessary to take into consideration modification of design of prosthesis for improvement of cleaning efficiency as well as simplification of prosthesis and easier recoverability of denture as the edge of patients is becoming higher and higher in these years.

    In order to offer better medical services and enrich people's lives, those employed in medical services need to consider not just technical aspects but also how to offer customer-friendly services. Therefore, to gain a better understanding of patients' view, we have conducted a questionnaire-based survey of 80 patients in our clinic.
    The survey showed that although patients take great interest in dental services, they have insufficient experience of oral health education; therefore we examined the results with this in mind.
