The objective of this paper is to analyze people's consciousness toward medical treatment at dentist and clarify the strategic market segmentation based on the influencing factors on the decision of receiving medical treatment. Through the survey of 2000 people in Shizuoka prefecture, it is clarified that there are ten segments based on five most-influencing factors. It is possible to raise the ratio of receiving medical treatment by implementing effective marketing measures which fit to the characteristics of each segment.

Observation of a maxillomandibular model, standardized and fabricated according to an occlusion plate based on anatomical mean values, allows for clarifying the opposing relation and the degree of ridge resorption in edentulous patients. Analyzing the standardized model serves as a preliminary examination of complete denture treatment, resulting in correct positioning and goal setting. Therefore, impression taking technique with anatomical indices and little shape deformation is necessary.

We have already explained in Part 1 and Part 2 from the view point of Kamiguse (habitual first stroke of mastication) concept that the TMD is caused by restriction of temporomandibular movement and release of this restriction is quite effective for trismus and TMJ pain. Not only the release technique but also the concept that TMJ pain and sounds are due to the restriction of temporomandibular movement were shown in part 1. And clinical case treatments for TMJ pain standing on this Kamiguse concept were illustrated in part 2. In this part 3 article, we show that our treatment method standing on this Kamiguse concept is extremely effective for TMJ sounds, especially for TMJ clicks that are assumed to be uncured and neglected, along with clinical cases.

The purpose of this article is to introduce the simple procedure that is used for recording the facial midline and horizontal line and in turn communicating this data to the dental laboratory. This procedure is carried out by using a small resin plate at the time of restoring the anterior teeth.

To obtain longevity of oral rehabilitations successfully, evidence-based examination and careful treatment planning are required. If standards of diagnosis and treatment planning are not firmly established the risk of treatment done in haphazard ways increases, making long term success of the cases difficult to achieve.
Among many treatment criteria for full mouth re-construction, this case report is focused on the criteria of occlusal section.

Even if it says that root canal treatment is the most frequent measures in our clinical measures every day, it will not be exaggeration. We tend not to be able to proceed the treatment when I avoid root canal treatment in the treatment of the old and middle age in particular. If there is deficiency for root canal treatment, it will be a castle in the air so that the prosthetic restoration which no matter how is splendid is attached to the upper part. In the dental treatment of full mouth reconstruction, there is even that an error of one root canal treatment has an influence on the whole treatment plan. I have wrestled with root canal treatment while wanting to avoid only the situation that re-treatment was necessary for the root canal measures that I gave. Because we clean the root canal which is the part we cannot see, the doubt stays in the certainty whether it is possible for complete cleaning with my ability. However, I think that I can increase the success rate even as for 1% by learning a correct diagnosis and skill and evaluating the convalescence of the tooth which I gave root canal treatment for objectively.
I show my action to increase certainty of the root canal treatment this time.

In clinical situations, it is common to treat teeth that have been treated several times before. Further, teeth with their biological width invaded by caries from the CK margin are often encountered. Those are usually not extracted, however, cannot be preserved as they are. Meanwhile, prosthetic pretreatment that moves teeth slightly can often expand the range of choices for treatment. Partial MTM orthodontic treatment in a few teeth with aesthetic and functional problems after specification of the therapeutic objectives can be a very effective treatment option. Herein, we present our approach and the results of some cases treated in daily clinical practice.

In implant treatment, GBR (guided bone regeneration) is frequently used in cases of severe alveolar bone resorption. However, there are few reports about bone quality at the GBR site replaced with bone. In the present study, inhomogeneous clinical mandibular posterior teeth defective models were created based on CT values. Bone quality at the GBR site was changed from D1 to D4 in the Misch's bone quality classification, and the diameter of the fixture to be placed was also changed. Finite element analysis was performed to examine the mechanical effect of bone quality at the GBR site on the peri-implant bones.
Results, discussion and conclusion: The harder the bone quality at the GBR site, the lower the maximum Mises stress was. Particularly, for bone quality greater than D2, a constant trend was observed regardless of the diameter of the fixture. Also, the thicker the fixture to be placed, the lower the maximum Mises stress was. Particularly, when the diameter of the fixture was thicker than a certain level, the maximum Mises stress showed a constant trend regardless of the bone quality at the GBR site. For bone quality D1 and D2, the position of the generated maximum Mises stress was located at the peri-implant superficial alveolar bone; for bone quality D3 and D4, the position moved to near the boundary region between the GBR site and the original mandibular bone. It is not that the harder the bone quality at the BGR site, the better. Rather, it is suggested that the harmony with the original mandibular bone is important.

At the turn of the twentieth century, periodontal regeneration has gain much attention due to its ability to restore the lost periodontium once was thought difficult to regain. In doing so, periodontal regenerative therapy has even contributed to the retention of severe periodontally involved hopeless teeth. However, this treatment modality had soon met great resistance by the emergence and steady growth of dental implant which claimed to have the ability to replace poor diseased natural roots with a better future.
It is the purpose of this paper, from the therapeutic perspective of a clinical periodontal practitioner, to develop a judging principle utilizing cross matching of prognosis and strategic value of the severely involved teeth with periodontitis to determine the optimal choice for periodontal regeneration or dental implant. In addition, the clinical significance and limitation of various periodontal regenerative procedures will also be discussed in terms of quality and quantity.
Careful evaluation must be exercised as a periodontist providing the best capability in preserving natural dentition for the maximum benefit of the patient.

The widely established regenerative procedures have recently begun to be applied to implant therapy and the treatment of periodontal diseases. In these cases, although a variety of materials are used for bone augmentation, the use of appropriate bone replacement materials is important. The authors are currently using three bone replacement materials, β-TCP (absorbable beta-tricalcium phosphate) (trade name: OSferion), Bio-oss, and autogenous bone. In this paper the authors introduce their views with regard to the proper use of β-TCP by employing knowledge of the characteristics of β-TCP, the selection of therapeutic uses, as well as the details of actual cases.

In spite of its high esthetic and biocompatible properties of the all ceramics restorations, it was not applicable for the clinical usage with molars, especially fixed partial dentures, due to its mechanical weakness. It is reported in the recent studies that zirconia has high bending and ultimate breaking strength, thus is more durable to the fracture in comparison with the other ceramic systems. All ceramics restorations with zirconia copings now can be used for the posteriors fixed bridges.
In this report, prosthetic procedures for fabricating all ceramics restorations with zirconia copings on both sides of the mandibular molars are described.
