摘要
The invention relates to a series of rubber dam retaining devices which use cervically directed forces to cervically retract and retain a rubber dam below the gum line in the mouth of a patient during dental treatment. The series includes two classifications of cervical retraction and retaining devices; intra-arch clamping devices which utilize inwardly directed reciprocal force to attach directly to a tooth for retention and inter-arch retaining devices which utilize the reciprocal forces of the upper and lower alveolar arches to retract and retain a rubber dam in the mouth of a patient during treatment. The invention has implications for general field isolation in dentistry, conventional isolation, and a hybrid type of isolation which involves both conventional isolation and general field isolation simultaneously.
