It is recognized that regular maintenance has control over tooth loss. But, when patients are analyzed in detail, it is found that there are some cases of multiple tooth loss regardless of dental maintenance. 268 patients of the middlescence with reliable clinical records among the patients having visited for more than 15 years were analyzed revealing that 27 patients (about 10% of the total) lost about half of their teeth (218 teeth out of a total 414 lost teeth). The samples were divided in two groups, those who received more than three maintenance sessions as the 'maintenance group' and those who received no maintenance as the 'non-maintenance group'. These groups were examined from 20 years of-clinical records to reveal that: the maintenance group lost an average of 1.4 teeth while the non-maintenance group lost an average of 3.3 teeth. This is more than double the difference between them. It verified the importance of maintenance. Among the maintenance group, there were 18 samples who lost more than 5 teeth mainly due to severe periodontitis or restoration.
