Wrap-around caries

1 Jun 2016 - 39191

Wrap-around cases are twice as difficult to manage and restore: it is not an easy procedure, therefore the treatment should be as conservative as possible. In this case a modified class two is combined with cervical decay.

Cervical non carious lesions are very hard in isolation, finishing and polishing. In this case the decay only was removed and the intimate contact preserved. In addition, part of it had been restored via injection over molding technique, which is very beneficial in unaccessible areas and where you need perfect adaptation.

Frontal view for the Bioclear matrix band showing its various merits: it is a clear one that allows the penetration of the light to accurate depth and does not affect the curing depth of the restoration, plus it is pre-curved so that it takes the normal shape of the tooth eliminating the need for ring or wedges and for pre-burnishing effect.

Preserving tooth structure by removing the decay only increases the integrity of the tooth structure. Injection over molding technique is very useful in unaccessible areas with the merit of perfect adaptation.
Three steps of polishing influence the final result of the restoration and improve its durability.
