Abstract
The status of plaque control after placing of endosseous dental implant was investigated.
Seven patients in whom the IMZ implant was placed into the posterior region were selected as the experimental subjects. These patients were instructed on toothbrushing until the O'Leary plaque score became 25% less before implant operation. The plaque score was recorded on day 1, day 3 and day 7 after implant operation.
Plaque score was 31.0% before operation and 45.4% on day 1, 39.5% on day 3 and 28.6% on day 7 after operation. However, the plaque score after operation was not statistically higher than before operation.
The result suggested that the implant operation did not disturb the plaque control in the patients with missing posterior teeth.
