Longevity of Indirect and Direct Restorations in Anterior Teeth

Abstract

It is the aim of this paper to present data on the survival of direct and indirect restorations in anterior teeth. Two sources of information are used: previously-published analysis of data from 1990 to 2006 from a 13 million restoration dataset from England and Wales; and evidence from published literature from 2011 to the time of writing (March 2022). The findings suggest that: (1) directly-placed resin composite materials may provide satisfactory survival of restorations in anterior teeth; (2) crowns provide better survival to re-intervention: however, crowning an incisor or canine tooth, as opposed to placement of a direct restoration, will lead to an earlier time to extraction of the restored tooth; (3) veneers perform more favourably than other restorations in terms of time to extraction of the restored tooth, but may have a less favourable time to re-intervention than crowns; (4) lithium disilicate crowns may be considered to perform satisfactorily with regard to time to re-intervention when placed in anterior teeth, but less satisfactorily in posterior teeth; and (5) operator factors influence survival of restorations.
