4) Missing or missing one or more molars (back teeth)
5) The patient's written consent to participate in this study has been obtained.

5) Patients who are or have been alcohol or drug dependent
6) Patients with a QTc greater than 450 ms on the standard 12-lead electrocardiogram at the screening test.
7) Patients with implants in the molar region
8) Patients whose clinical examination (hematology, blood biochemistry, infectious disease test, and urinalysis) is judged to have clinically significant abnormalities by the investigator (subinvestigator)
9) Patients who have participated in other clinical trials and received an investigational drug or study drug within 16 weeks prior to the start of administration of the investigational drug
10) Received or used any drug (prescription or over-the-counter drug) within 1 week prior to the start of administration of the investigational drug. (However, topical antiseptics, eye drops, etc. that are considered to have no impact on the pharmacokinetics or safety of the investigational drug if used, such as no systemic exposure, are acceptable.
11) Patients who have donated 400 mL or more of blood within 12 weeks prior to the start of treatment with the investigational drug, or who have donated component blood or 200 mL or more of blood within 4 weeks prior to the start of treatment with the investigational drug.
12) Patients with a history of infection within 1 week prior to the start of treatment with the investigational drug, or patients with apparent infection at the time of examination on the day prior to the start of treatment with the investigational drug, who are judged to be inappropriate by the investigator (subinvestigator).
13) Patients who have received a live vaccine within 4 weeks prior to the start of administration of the investigational drug or are scheduled to receive a live vaccine during the study period (by the day of visit 57 after administration of the investigational drug)
