Abstract
Purpose : Dental implant treatment has become established as an effective method with a good prognosis. However, prob lems of complications are spreading with the growing availability of implant treatment. Especially, complications in maxillary implant treatment can be severe due to the specific histological and anatomical properties. On the other hand, the recent progress and spread of diagnostic equipment is expected to help reduce complications. In this study, a questionnaire survey was conducted to clarify the current status of complications, treatment techniques, and the spread of equipment.
Method : A questionnaire survey of complications in maxillary implant treatment and medical equipment was conducted, targeted 51 certifying and supervisory doctors of the Japanese Society of Oral Implantology in Hokkaido for three years (April 1, 2012 to the end of March 2015).
Results : The complication rate of maxillary sinusitis was 57% in supervisory doctors and 36% in certifying doctors. Perfo ration of the maxillary sinus floor mucosa was 57% in supervisory doctors and 33% in certifying doctors. 93% of supervisory doctors and certifying doctors perform a CT-scan examination before surgery. 79% of supervisory doctors and certifying doc tors perform diagnosis using simulation software. 49% of supervisory doctors and certifying doctors perform computer-guided surgery.
Discussion and Conclusion : Many complications of maxillary implant treatment were related to the maxillary sinus. The introduction of digital equipment was found to be progressing rapidly. The progress and spread of digital diagnostic equip ment is expected to reduce the incidence of complications, but complications of maxillary implant treatment are still experi enced with a high probability by supervisory doctors and certifying doctors.
