    This paper is to present a case of a patient with moderate periodontal disease and dual bite and discuss importance of assessment and diagnosis and how to utilize splint to achieve stable occlusion.<Clinical Summary> At the time of the first visit the female patient was 60 years old; probing pocket depth exceeded 6mm in some areas; in the occlusal examination lack of occlusal contact was observed in the molar region at the habitual closure position; and cuspal interference occurred on the left and right second molars during lateral movement and group function were seen on both sides. Premature contact occurred between 7 and 7 upon the closure with the jaw muscles relaxed. <Therapeutic Process> The patient was instructed to wear stabilization splint at all time, and mandibular position was check every 3-4 weeks along with adjustment of the splint. Over the course of this treatment provisional restoration stayed intact, and neither washout of temporary cement nor temporomandibular disorder occurred. Determination of mandibular position by stabilization splint does not only avail accurate diagnosis, but also help realizing patient specific and stable condylar position, which greatly merited the subsequent prosthetic procedures and helped keeping mandibular position stable.

    Patients who have lost occlusion support in the molar region are vulnerable to problems such as decreased sensory input from the periodontal membrane due to tooth loss, reduced vertical dimension of occlusion, and displacement of the mandibular position. Given these problems, consideration of factors involved in function and facial form balance, such as recovery of mouth volume, correction of the mandibular position, and rejuvenation of the muscles around the oral cavity, is important when planning prosthodontic treatment for missing teeth. In the treatment described here, treatment dentures were placed in the maxilla and mandible of a patient with few remaining teeth, who had the symptoms described above, in order to reconstruct a functional masticatory system (sensory input system, central processing system, motor output system and peripheral effector system). Following placement of the dentures, the patient underwent rehabilitation and training. Six months after the start of treatment, the mandibular position was stable, and there was improvement in the mastication disorder that had been the patient's chief complaint; thus, permanent dentures were placed in the maxilla and mandible.

    When facing a patient with malocclusion and malalignment, in the course of the therapy it is imperative to look into patient's past and ask yourself, “Why and how did this patient's occlusion reach this pathological state?” Narrowed arches, difficult and ineffective orthodontic treatments, and post-operative regression of the condition are may be at least partly caused by tongue, labial, postural habits of the patients. Here are presented three cases—an orthodontic treatment which saw post-orthodontic regression of the condition, malalignment caused by nail biting habit, and malalignment at least partly due to postural habit—where improvement was brought by instructions on tongue, labial, and postural habit.

    In this case the patient first visited my dental clinic with a chief complaint of mastication difficulty, seeking a third opinion. The patient's occlusion prima facie did not seem pathological and in such case the patient's complaint tends to be interpreted by a clinician as an indefinite complaint. In the present case, seeking an indication of a functional aberration in exchange with the patient, I started to notice some morphological abnormality and was eventually able to share understanding of pathological and clinical conditions with the patient. After some trials and errors I was able to truck down the cause of abnormality, namely, ill-fitting prostheses, which were then replaced with provisional restoration. At this stage, inconformity problems were mostly alleviated. The immediate post-operative outcome was agreeable; this still needs a long-term follow-up.

  • Recovery of the severely resorbed condylar by conservative treatment —a case report of degenerative joint disease

    This paper is to report a case of a patient with condylar resorption, control of which lead to continuous repair reaction and amelioration of degenerative joint disease. The 22 year-old female patient first came to the clinic with a chief complaint of lockjaw and joint paint. Orthodontic treatment had finished 3 years before; at that time molar intercuspation and open bite in the anterior region were apparent. Based on the x-ray image, the patient was diagnosed with temporomandibular joint osteoarthritis and provided conservative therapy. As occlusion stabilized, condylar resorption ceased and continuous repair reaction followed. In this case occlusal stability was the key to improvement of the pathological condition.

  • Application of mini-screws to improve positional reproducibility of the diagnostic stent in surgical guide placement—in an edentulous implant case

    In an edentulous implant case the poor reproducibility of positioning of the diagnostic stent for dental CT scan and surgical guide often poses a challenge, resulting in placement of implants in a position differing from the treatment plan. In this paper is presented a case in which miniscrews were employed in order to improve reproducibility in positioning of diagnostic stents and surgical guides. As a result, placement of mini-screws did not only improve positional consistency between diagnostic stents at CT taking and surgical guides, but also stabilized the surgical guide in the implant surgery. Also mini-screws proved effective in supporting treatment dentures and protecting the wound surface.

    Traditional dentistry provided restorative treatments for carious teeth, periodontal therapy for mild-moderate periodontal disease, periodontal prosthesis for severe periodontal disease, and dentures for missing teeth. Now the implant is added to the list of treatment options, and patients' demand for aesthetic outcomes have become more apparent—in short now patient's opinion weigh in selecting a treatment option more than ever. Whatever the treatment option the patient and dentist may end up choosing, stable occlusion remains important for the maintenance of oral health. In a case where occlusal reconstruction is necessary, stable centric occlusion, vertical stop, and anterior guidance along with resultant disclusion and anterior coupling continue to be the primary therapeutic targets regardless of a variety of treatment options. This report is to present a case of a patient with pathologically displaced mandibular due to a long-term chewing habit. The treatment arrived at an agreeable outcome as a result of prioritization of the occlusal treatment, continuous and careful adjustment of the mandibular position based on the principle of minimal intervention onto tooth structure, and remedy of compromised aesthetics, which was the patient's chief complaint.
