Clinical use of a novel audio pillow with recorded hypnotherapy instructions and music for anxiolysis during dental implant surgery: a prospective study.

A prospective, comparative study of a novel audio pillow with hypnosis text and relaxation music was conducted in 82 dental-implant surgery patients to relieve anxiety over a 6-month period. Visual analogue scales combined with the Aachen Dental Treatment Fear Inventory (AZI) questionnaire were used to quantify patients' subjective feelings of fear. Blood pressure, heart rate, and capillary oxygen partial pressure were measured before, during, and after surgery. The AZI scores decreased in the hypnotherapy group (n = 44) and increased slightly in the control group; scores were significantly different between the groups (p = .000). During surgery, the average diastolic blood pressure and heart rate decreased in the hypnotherapy group and increased in controls. Thus, this audio pillow with relaxation music showed anxiolytic effects in patients during dental implantation procedures.
