Abstract
|
|
|
The purpose of the study was to observe the time serial changes in proximal contact tightness after single crown
restoration. Initial proximal contact tightness before crown preparation and after prosthesis restoration were measured
repeatedly in 12 subjects. In consequence proximal contact tightness of temporary setting on prosthesis was bigger than
contact tightness before initial preparation, contact tightness of the prostheses of 1-2 weeks after the setting was similar
to that before the preparation, tightness of 2-4 weeks after the setting showed little change and maintained constant contact
tightness.
