Occlusal Veneer Versus Full Crown, Conservative Approach to Cracked Tooth Syndrome

Objectives: This paper aimed to provide a minimally invasive management with Cracked Tooth Syndrome (CTS) which is commonly encountered in dental practice.
Methods: 60 CTS molars were randomly divided into 2 groups, the occlusal veneer group (OV group) and the full crown group (FC group), and each group including 30 molars. The molars in the OV group were rehabilitated with occlusal veneer by lithium disilicate ceramics IPS e.max® CAD (LS2), meanwhile the molars in the FC group were restored with full crown by the same materials. After 1 month, 6months and 1 year the patients were recalled for clinical study.
Results: After 1 month, 6 months and 1 year follow-up, 58 molars were successful, one failed due to pulp complications (full crown group, 3 months), one restoration cracked (occlusal veneer group , 1 year). There was no significant difference between two groups (paired t test).
Conclusions: Occlusal veneers have the same success rate with full crowns in rehabilitation of CTS teeth within a year, though veneers require less preparation.
