    Quincke's Edeama is of intrest for dentists in clinical practice. It was first discribed in 1882 as a transitory and a localized edeama in the skin or in the subcutaneous tissue. It is known to angioneuroedema. Since it was first reported by Quincke, several articles have reported it.
    We report that we experienced a case of Quincke's Edeama. A case is reported to present the dentist's role in diagnosis of Quincke's Edeama.

    Occlusion, together with the morphology and position of the teeth, changes throughout a person's life. It also seems quite natural that deviation of the mandible occurs in conjunction with these changes. Observation of this phenomenon in mature adults over a period of ten years clearly shows that this is an aspect of physical health that can readily be confirmed by anyone. The extent of these changes is generally small in dentate individuals.
    In order to determine whether the situation should be considered a disease state, it is important to carefully investigate whether the oral tissues and function deviate from normal human physiological limits. However, when we carry out the same observations on an oral cavity where several teeth have been lost, it becomes obvious that these changes have accelerated. These effects are often seen in cases where treatment was done without a thorough evaluation and diagnosis of the dentition with missing teeth, and can be considered the result of the long-term use of a poor prosthesis that was provided. This can occur because the most important task of the oral cavity as an organ is mastication, and the surrounding tissues attempt to adapt to accomplish this task even though there is malocclusion. Maintenance of masticatory movements in this way result in deviation of the mandibular position owing to training of the muscles of mastication, and often creates establishment of a pathologic mandibular position.
    Although it is necessary to return the mandible to its normal physiologic position and movements, the methodology for this is in no way simple. In this particular case, I searched out the reasons for the patient's mandibular deviation, and using the evaluation and diagnosis of a dentition with missing teeth as a basis, present here in detail the thought process involved in the treatment and selection of the necessary target mandibular position for establishment of a physiologic occlusion.

    Clinical dental prostheses utilizing magnets have been reported since the 1950's. Nonetheless, the devices of that time had various problems and did not achieve widespread use. However, their use in the oral cavity became practical with the invention of samarium cobalt magnets, which possessed excellent magnetic properties. In recent years small, high quality magnetic attachments have been developed as denture support apparatuses. Among these, magnetic attachments that others and I use were made practical by Takanobu Tanaka in 1992.
    Unlike conventional retainers, magnetic attachments are special devices that support the denture by the force of magnetic attraction. Therefore, although they have several advantageous points, they have various problems depending on how they are used. While touching on their construction and characteristics, we would like to discuss overdentures, where the authors and others have often used magnetic attachments.

    About two years have passed since prosthetic treatment using osseointegrated implants have been introduced as a method of functionally and esthetically restoring edentulous patients. The introduction of the bone anchored bridge making use of osseointegrated implants has been good news for edentulous patients. However, although maintenance, which is a determining factor in the prognosis of implant prosthetics, is Just as important as it is for natural teeth, the problem arises that highly developed brushing techniques are required of the patient depending on the location and direction of placement of the implants. In addition, although bone anchored bridges have been fabricated using the conventional combination of artificial teeth and base resin that have been used for traditional dentures, there has recently been an increase in patients requesting a higher level of esthetics.
    The problems of function and esthetics of implant prosthetics have recently become a more important theme than they were in the past. Because we have again become aware of the importance of diagnosis and treatment planning that fulfills the requirements of both, there have recently been a large number of papers on this subject. Although the techniques and methods of these reports differ, they all express a common view that the location and direction of placement of the implant is an important factor in satisfying function and esthetics.
    In this case of an edentulous patient where a full denture was indicated for the maxilla and a bone anchored bridge with ITI implants was indicated in the mandible, a more esthetic superstructure design was selected by making use of provisional restorations and a surgical splint of twin tube steel. It should also be noted that greater esthetics were attained through build up of hard resin on the framework.

    Operations of the guidance apparatus are quick, it has many beneficial aspects, and is easy to use. The mandible is placed 30 to 60° with respect to the occlusal plane, it is supported at three points, and the device has a contact plane that is both strong and narrow in width with respect to the mandibular incisal region. In this way it is possible to isolate training and the habitual closing path. It is effective when used in conjunction with leaf wafers, and is thought useful in confirming a diagnosis of mandibular dysfunction. An apparatus for use with edentulous patients is currently under development.
    I would like a greater number of dentists to truly understand that the contact relationship of the maxilla and mandible that appears in the posterior closing path can be incorporated as a routine item for examination, and that it is possible to incorporate their removal in the treatment. It is important that the decision regarding removal of these contacts that interfere with this closing path should be made based on such factors as the degree of malocclusion, the necessity for restoration, and the condition of the temporomandibular joint, as well as the patient's physical condition and attitude and experience concerning previous dental treatment.
