Simplified trimming and finishing of glass-polyalkenoate (ionomer) cement restorations

Shaping and fine working of restorations necessitated by cervical lesions, abrasions at the necks of teeth, or root surface caries can often be arduous to complete. As an example of a facilitated trimming and simplified finishing technique for cervical restorations, the use of tissue-protective finishing diamonds to adapt a Class V Type II glass-polyalkenoate (ionomer) cement restoration is demonstrated. Because of their noncutting guiding tips, these safe-ended diamond instruments can ehlp prevent discontinuous and nonanatomic contouring of restorations. In additiion, these special instruments allow a less traumatic working procedure in areas of marginal gingiva.
