Overlay on non-vital tooth
The protection of the cusps on a non-vital tooth is very important to reduce the risk of fracture
Initial occlusal aspect
Initial x-ray, you can see the D4 lesion in the mesial part of 15.
Isolation with the rubber dam.
Pulp exposure during decay removing.
Aspect of the tooth after endodontic treatment and the post space preparation on palatal root canal.
Adhesive phases for the fiber post cementation and build-up stratification, etching for non-vital tooth is from 30 to 60 seconds, aspect after washing out of the etching agent.
Digluconate solution of chlorhexidine at 0,2% to inhibit metal-proteinases, primer, drying primer on the canal with a paper point and the last picture with the adhesive application.
Fiber post conditioning with silane and a thin layer of bonding agent.
Fiber post cementation with dual cure composite cement and the stratification of a micro hybrid composite to complete the build-up.
Composite overlay conditioning, the etching agent is only used to clean the internal surface of the restoration.
Composite conditioning: alumina sandblasting, silane and bond.
Overlay check before rubber dam positioning, isolation and adhesive steps: etching, chlorhexidine, primer and bond (without curing it).
Heated micro hybrid composite used for cementation, proximal floss to remove the excess, sonic tip for cementation, glicerine air-block for the last cure, different final point of view.
Buccal aspect and final x-ray aspect.
Partial indirect restorations with adhesive cementation are, today, the first choice to restore single non-vital tooth, with this kind of restoration we can protect the tooth from the occlusal strength and we can ensure to the patient a good esthetic result and a biologically conservative kind of restoration.
