Abstract
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.
