New techniques for producing aesthetic, direct full-crown composite resin restorations for primary molars: a 24-month follow-up study of eight cases.

AIM Although the demand for aesthetic restoration of primary molars has increased, techniques for producing aesthetic, direct full-crown restorations using light-cured composite resin for primary molars and the associated clinical outcome are not well established. The aim of this study was to describe the use of new techniques to produce aesthetic, direct full-crown restorations using light-cured composite resin for primary molars. The authors evaluate the clinical outcomes of the restoration method and investigate whether this technique could be used as an alternative to conventional methods. MATERIALS AND METHODS Two new techniques, the resin block and the clear matrix, were studied by treating 8 teeth. The occlusal surface of stainless steel crowns was used for impression-taking to facilitate accurate reproduction of the anatomic structure, and the aesthetic restoration was obtained simply and consistently. RESULTS At the 24-month follow-up evaluation, these new direct techniques were completely satisfactory. Marginal discoloration was observed in one tooth treated with the clear matrix technique, and a small partial wear was observed in another tooth treated with the resin block. CONCLUSION The new techniques for restoration resulted in functional and aesthetic reproduction of occlusal morphology. Therefore, these techniques could be considered a practical alternative to conventional methods.
