Fig. 9. The types of abutment and connection. (A) Abutment margin system for sufficient inter-arch distance. Simple retrievability can be possible due to using upper bevel in TL. (B) Fixture margin system for limited inter-arch distance. Favorable crown shape can be possible. However, the removal of excess cement and perfect seating would be difficult in some cases.
