Muh shield（ YC3） was developed to improve the overjet and overbite in the primary dentition. However， there have been no reports on an annual growth amount evaluation using Muh shield in young anterior cross bite patients. As such， we have applied on Muh shield in 12 young patients with anterior cross bite. The aim of this study was to examine the treatment effects of the Muh shield in correcting a young anterior cross bite patient. The average values of an annual growth amount in 12 anterior crossbite patients show skeletal improvement. Specifically， mandible bone growth amount has controlled under the treatment period. The use of Muh shield might be effective because it has a function of tongue-up. As results indicate that the use of the Muh shield improves functional effects on the skeletal system.We will progress further study in the near future.

Anatomical landmarks in edentulous casts provide references and essential information for denture manufacturing to the dental technicians at the laboratory. This research is to investigate desirable denture manufacturing methods and process for dentists through questionnaires regarding the landmarks of edentulous their casts and actualns of casts we receive using the landmark chart (which for s as reference upon configuration of denture plate). Objective: to investigate complete denture manufacturing dentists set out for and to optimize quality and process process of denture manufacturing incorporating dentists' voice. Method: questionnaires on full denture manufacturing process and anatomical landmarks as well as observation of the casts sent to the lab using the landmark chart. Result: the most popular manufacturing process was <preliminary impression → custom tray → bite taking → trial insertion/placement → finish> (51%). There was a considerable gap in appreciation of-hence, articulation in the cast of-the mandibular landmarks. Discussion: from the result of the attitude survey, it is clear that many dentists hopefor complete attachment of complete denture (all around baseplate), but actual approach in impression taking of edentulous jaws and articulation of the anatomical landmarks on the casts show large variations.

Given the individuality and specificity of each patient's conditions and background, oral hygiene instructions, if uniformly prescribed to every patient, may not serve their purposes. In the current trend of dental practice personalized care as to meet each patient's need is becoming increasingly important. Discussed in the present paper are cases of patients with different symptoms and chief complaints such as tooth erosion and dentin hyperesthesia and also different methods for different gingival conditions. Introduction of a new tooth cleaning method—with glycine powder—is also included.

Although implants have been recently used in treatment for various cases， partial dentures have also been frequently used in prosthetic cases for missing teeth in daily dental practice. However，patients with distal-extension missing often experience many adverse symptoms or complaints，including appearance of pain due to denture settling and vertical displacement due to rotation of the denture. Therefore， I believe that use of implants is essential for establishment of vertical stop in the multiple posterior defects case. In contrast， implant treatment involves a relatively high level of surgical stress and a heavy economic burden on patients due to expensive treatment costs. Thus， treatment was performed with the implant-supported overdenture， which can induce the rest effect for obtainment of denture stability in this case， resulting in excellent results.

The occlusal plane is normally evaluated for occlusal reconstruction in prosthetic treatment. It has a major effect on the anteroposterior position of the mandible and mandibular opening and is an important factor in deciding the skeletal pattern. The upper occlusal plane（ UOP） is a reference plane used for occlusal reconstruction and its evaluation and diagnosis are key points in prosthodontic therapy. The patient with high angle class II open bite presented with a v-shaped occlusal plane（ consisting of a flat maxillary anterior occlusal plane and steep maxillary posterior occlusal plane） and a steep mandibular plane. The deficiency of the occlusal vertical dimension in the molars caused the mandible to be rotated in a posterior direction（ rotated clockwise and expanded）， resulting in open bite. In such patients， active occlusal plane reconstruction and anterior repositioning of the retruded mandible are important. The therapeutic steps taken in this patient are described here.

In daily clinical practice of dentistry， comfortable chewing is the ultimate goal shared by patients and dentists， and， hence， occlusion is of great importance. There are a wide variety of methods and devices employed in occlusal examinations and analyses such as: study cast， dental X-rays， and electronic registration of mandibular movements，but the importance of the simplest method，namely，physical examinationwithout any special device，which imposes little stress on patients，should not be discounted. Though proper anatomical knowledge and just observations are imperative， the physical examinations should be considered as a basis for occlusal diagnoses. This is a report of successful case of treatment (including orthodontic procedure and correction of mandibular position) based on the relational analysis of mimic muscles， masseters， gnathofacial structures， and mandibular deviation.

Enamel is the hardest tissue in the human body and is considered to be valuable because it cannot be regenerated if damaged. Therefore， the benefits and risks of removal of sound tooth structures should be carefully examined before prosthetic treatment. Over 20 years have passed since the introduction of prostheses using bonding bases for retention following orthodontic treatment. These can be applied in bounded edentulous spaces to replace a small number of teeth， and may prevent secondary occlusal trauma in teeth with moderate to severe periodontitis. Given that the metal is exposed， which confers an unaesthetic appearance even for a prosthesis applied on the lingual side， it is surprising that these prostheses have remained in use for such a long time. Connected crowns and bridges should be considered only if necessary. If cutting the teeth and not cutting the teeth at all are compared， which method should be selected if there is no major difference in effects? The answer is clear in light of the concept of minimal intervention（ MI）.

The patient with concern for cosmetic dissatisfaction was referred by a general dentist to our clinic for orthodontic treatment. My task was to create space required for prosthetics. Based on various assessments and analyses， this was diagnosed as a borderline case falling between surgical orthodontic and normal orthodontic treatment. After discussing the details of the case with the prosthodontist， we decided to avoid surgical procedure and to adjust occlusal relationship by prosthetic treatment after orthodontic treatment. Dental implant treatment was needed after orthodontic treatment， and space for the maxillary central incisor implant was acquired as planned at the time of diagnosis. A detailed treatment plan is required for a treatment that involves orthodontic and prosthodontic interventions. Treatment plan was set based on limit of tooth movement by orthodontics and simulation by VTO. This is a case where interdisciplinary approach was taken to achieve occlusal stability and aesthetic improvement.

Today, there are three kinds of energies which are overlooked in medicine, viz: 1) environmental energies, 2) energy metabolism of organella mitochondria, and 3) biomechanical energies, evoked by animal movement and behavior. For these reasons, the mechanisms of evolution of vertebrates as well as the development of the tissue immune system, and the mechanisms of an attack of intractable maladies, are completely unknown. Introducing these three kinds of energy into modern medicine the author has established Stomato-facial and Neuro-cranial medicine. Thereafter, he investigated the unified simple system of ultra-multicellular animals, from the standpoint of organella mitochondria which control them from inside cells. After that he established mitochondria-based pathology where by seven kinds of causes of mitochondrial deterioration can induce intractable maladies.Not only immune diseases but also carcinoma and mental diseases are induced by means of improper environmental energy, during which enteromicrobes are incorporated into leukocytes, which in turn change into granulocytes circulating in blood vessels in the whole body, which disseminate enteromicrobes into cells in various organs giving rise to intracellular infection. He disclosed via clinical research that by drastic change of recent lifestyles, the symptoms of opportunistic infections change into fulminant as if the symptoms appear to be quite different maladies. Mental illness, Intractable immune diseases and Carcinoma are all the same maladies. Therefore, the therapeutic methods of three kinds of major intractable maladies are all the same. The author has surveyed these patients via the Bi-Digital O-ring Test detecting intracellular infections of the organs as well as effective antibiotics and/or antiviral agents. After that, he has developed mitochondria activating therapeutic methods (abbr. M.A.T.M) and applied them to these diseases. Five clinical cases are presented. Via these administrations concomitant with remedy of improper energy of lifestyle maladies can be cured, if treated in time.
