Abstract
Marginal openings before and after cementation has been measured on freshly extracted teeth. This study measured marginal openings after cementation on natural teeth in a many teeth treatment case for examining the compensating effect of periodontal ligament in oral cavity.
1. Maximum marginal opening after temporary cementation was 0.26 mm in maximum.
2. Maximum marginal opening after final cementation was 0.16 mm in maximum, that is, 0.08 mm larger than the value on extracted teeth and 0.10 mm smaller than the value after temporary cementation.
3. Decrease of maximum marginal openings from“after temporary”to“after final”cementations can be attributed to the effect of the remount procedure performed between the temporary and final cementations.
