If not only controlling progression of disease but also restoration of damaged or lost tissues was possible, periodontal treatment would come close to its ideal. Presented here is a case of 56 year-old female patient with a chief complaint of swollen gums in the upper right region. Probing depth was greater than 6mm at multiple sites, and the patient was diagnosed with generalized moderate-severe chronic periodontitis. For the vertical bone loss at 3 2 and 7 , after thorough basic periodontal treatment, various methods such as natural movement of teeth, enamel matrix derivative for periodontal tissue regeneration, and limited orthodontic treatment were employed to achieve long term stability. X-ray examination at 3 year follow up presented improved, stable periodontal tissues.
Functionally discluded occlusion (FDO) is based on group functioned occlusion theory. FDO is focusing on the physiologically harmonized occlusion. Diagnostic wax up and planning wax up to give a patientʼs own four inches spherical surface was done to treat with this FDO based restoration. Then, provisional restoration was made. The patient with FDO prosthesis was able to gain physiologically harmonized occlusion without occlusal adjustment. He feel very comfortable with it. So I assume that provisional restorations considered FDO has huge advantage. This report is the clinical case of this method.
In the previous report (the first report) reported was the outcome of splint therapy with a simplified bite-taking splint for patients with toothache, hypersensitivity, and temporomandibular joint disorders, etc, in short, functional disorders perchance due to excessive occlusal force (1st report). The logic of this therapy is supplemented by long-term follow up as over the time course there are many factors involved in the incidence of functional disorders including biological reactions. The age of 10 long-term follow-up patients at the initial visit ranges from 4 to 58 years old. A case of splint therapy involving suspension of an old splint therapy is included. The outcome strongly suggests ①effectivity for early mild symptoms and ② occlusal care in the development period.
In a case of posterior bite-collapse, the digital jaw motion measuring device was employed to assess functional movements of the mandible, aiming to acquire objective information from provisional restorations and provide a diagnosis based on scientific evidence. Based on the analysis by the jaw motion measuring device, provisional restorations were assessed again, and the occlusion was reconstructed. In the process of this occlusal reconstruction, provisional restorations are replaced by final restorations, and this is where the dentistʼs intuition and experience are called upon. Presented here is a satisfactory result of such case.
In clinical dental practice, we often stumble upon on a case where the patientʼs chief complaint is concerned with a certain part of the mouth, yet a comprehensive care plan based on “the entire mouth as a functioning unit” is required in order to provide treatment aiming for stable stomatognathic system. Presented in this paper is a clinical case of a patient with a complaint of deep subgingival caries and tooth mobility. Preservation of the relevant tooth deemed unrealistic after the detailed examination. On the entire mouth, malpositioning of some teeth, malfunctional occlusion, and some periodontal problems were detected. As such, comprehensive treatment plan was drawn taking into account specialistsʼ advice on each problem. Along with this master plan, the carious teeth were restored; periodontal therapy and orthodontic treatment were provided; and finally, implant treatment was carried out upon completion of bone augmentation with tooth extrusion. Adequate occlusal relation and periodontal environment were maintained, and the patient was satisfied with the result.
Proper denture treatment for edentulous patients—provision of retention of mandibular complete denture in particular—requires long clinical experience. The authors believe that it is important to include maxillary and mandibular landmarks in the impression, determine mandibular position based on anatomical and physiological grounds, and then arrange the prosthetic teeth and gingival shape with consideration for occlusion, speaking ability, esthetics, and preservation of tongue space. In order to properly take functional impression, irrespective of clinical experience, dynamic impression is taken with a duplicate denture fabricated based on the old mandibular denture and relevant landmarks. The vertical dimension is determined with interocclusal distance, facial features, speech function while the horizontal position—in other words centric relation—is determined based on Gothic arch tracing; and the artificial teeth were arranged with consideration of incisive papillae and external appearance for the anterior region while those in the molar region were arranged in accordance with the Poundʼs and Payneʼs line.
More than half a century ago, the konus telescope crown (hereinafter referred to as konus) was developed by Körber. The konus is applicable to a wide variety of cases including before and after prosthetic treatment. In my opinion the konus is completely different from many other prosthetic methods. Other treatment methods cannot be carried out in a seamless manner, but the konus can. In Japan, however, the konus has not found a definitive role in the general and comprehensive dental care system, albeit its maintainability and predictability over the course of life after the treatment. In this paper, I rethink the essential clinical significance and value of the konus that had not been before discussed thoroughly in Japan. I would like to report my conclusion that the konus can be used as a general, inclusive, concrete and practical dental treatment system in comprehensive prosthetic treatment including before and after the prosthetic treatment.
The complete dentures were adjusted with remounting procedure for the 82 year-old female bedridden blind patient at a special nursing home. This procedure did not only restore the patient's chewing ability and cephalic presentation, but also motivation for eating and rehabilitation. Two months after the denture adjustment, the patient started trotting about with help of a walker. Restoration of chewing ability might have been the catalyst for restoration of walking ability.
In this paper, the concept of temporomandibular disorders (TMD) was outlined. TMD is a collective term embracing all the problems relating to the temporomandibular joint and related musculoskeletal structures. The patients who have masticatory muscle and/or joint pain, joint noise, or problems in jaw movement without well-known etiology are exclusively diagnosed as TMD. Therefore, TMD contains multifactorial nature of conditions, including masticatory muscle pain disorders, joint pain disorders, disc derangement, and osteoarthritis/osteoarthrosis.
