When delivering a full-arch zirconia implant-supported prosthesis, an infrequent but possible complication is the fracture of the zirconia framework. This complication can be seen more commonly on patients who exhibit parafunctional habits.
This visual essay walks through the basic steps of temporarily repairing a fractured implant-supported zirconia prosthesis.
As you will see in Figure 7, I provide a step-by-step reparation protocol:
- Sandblast two bars of A102 (110 microns)
- Silane one minute per surface
- Allow five minutes to evaporate
- Apply bonding agent
- Cementation utilizing dual curing resin cement
This is a step-by-step technique on how to repair a fractured zirconia implant-supported framework. It is important to clearly communicate to the patient that this is a temporary repair while a new zirconia prosthesis is fabricated, but it allows to address the emergency in a relatively easy and inexpensive way.
