 note = {In the last two decades, the Shortened Dental Arch (SDA) concept has been introduced as a treatment strategy for posterior edentulous patients; i.e. there is no need to restore the missing part of the molar region. However, clinical experience suggests various possibilities for functional disturbance starting from instability of occlusion. This study investigated whether the SDA concept applies to all posterior edentulous patients. Fifteen patients with unilaterally posterior missing teeth were enrolled in this study, and multiple evaluations of SDA were performed in these patients. This evaluation consisted of an objective evaluation (radiographic evaluation for temporomandibular joint and measurement of condylar displacement during maximal voluntary contraction) and a subjective evaluation (questionnaires about satisfaction with several oral functions). Abnormal condylar appearances were observed in eleven subjects by radiographic evaluation and these phenomena coincided with edentulous-side in six subjects. Condylar displacement during clenching was significantly larger on the edentulous-side compared to that in the dentulous-side. Regarding the subjective evaluation, masticatory problems were the most serious complaint in patients with SDA. These findings indicated the potential risks for oral functions. We propose that clinical guidelines should be developed for determining whether to adopt a "Wait and See" approach for SDA patients without any proactive treatment, or to start prosthetic intervention immediately., application/pdf},
