Description

<p>Since 1996, the Department of Dental Implant Clinic, Tokyo Medical and Dental University Hospital (former Dental Implant Clinic, Tokyo Medical and Dental University Dental Hospital) has been reporting on the trends in new patients every five years. The total number of new patients, gender distribution, age distribution and reasons for their visit for each five-year span were calculated and analyzed considering the social background. The following results were obtained.</p><p>The number of new patients increased markedly from 275 in 1996 to 1,643 in 2011, then showed a decreasing trend until 2021. The male-female ratio was 1 to 2 almost every year. The most common age brackets of new patients were 40s and 50s in 1996, 50s in 2001, 50s and 60s in 2006, 60s in 2011 and 50s in 2021. About 80% of the reasons for visits were requests for dental implant treatment. The number of patients who had complaints about implant treatments at other clinics increased from 1996 to 2011, in 2016 was almost the same as in 2011, then decreased in 2021.</p><p>We assumed that the number of new patients and the decrease in number of elderly patients were related to the impact of the coronavirus pandemic.</p>
