Conclusions

In summary, Itena Clinical's resin core build up material and fiber posts can provide excellent restoration results if managed properly. Adequate steps for dentine or enamel preparation before and during bonding should be carried out for optimum result. Moreover, the clinician should respect all stages of the adhesive techniques taking special care for the time frame during etching and bonding of the tooth structures.
