Patient-reported Outcome Measures Comparing Static Computer-aided Implant Surgery and Conventional Implant Surgery

MDAS was used to measure the patients' anxiety toward dental treatment before implant surgery (Humphris, Dyer, \&Robinson, 2009). Originally, the MDAS questionnaire included five questions answered with a 5-category Likert scale. The original MDAS questionnaire does not cover anxiety toward implant surgery. Therefore, a question enquiring about patients' feelings towards implant surgery was added.

Patients were asked to describe the worst pain feeling using a standard 10 cm Visual Analog Scale (VAS) and the proportion of time spent in severe pain using a 5 category Likert scale. The number of analgesics taken per day was also asked.

The OHRQoL comprises 14 questions covering problems the patient may in three main categories: oral function, daily activity, and post-operative symptoms (Chaushu, Becker, Zeltser, Vasker, \& Chaushu, 2004). Patients answered using a 5-category Likert scale.
