[Use of post-core retained full crown].
In the recent three years, 60 posterior teeth with large defects have been restored by the author with the post-core retained full crown. The methods used in restoration included spiral-shifted post, spiral pin, light-curing resin core and amalgam core. This technique has the advantage of manipulating simply and mastering easily. All of the cases were followed up for a period of 9-19 months. The results show that loosening and dislocation of the crown and secondary decay of the teeth have not been revealed. There was one case in which the crown had caused irritation to the gingiva. The success rate of restoration is 97%. The masticatory force after restoration ranges from 15.9-26.9 kg in average which is much more than 10-23 kg in most individuals. This force may satisfy the requirement of masticatory functions. For the preservation of residual roots or crown, this method of restoration is of value both theoretically and practically.
