Retrievable cemented crown options on implant-supported angled abutments: a case report.

Nonaxial implant alignment often predicates the use of cemented of screw-retained angled abutments with inherent disadvantages, including reduced retrievability on screw loosening. The purposes of this article are to review the relative merits of cemented and screw-retained angled abutments and to present a method of ensuring retrievability of cemented angled abutments.
