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

Authors:

ABSTRACT

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.

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.
