After months of lockdown due to the pandemic, dental offices are starting to reopen and patients are returning. It’s likely many of them will have emergencies and broken restorations that will need to be repaired. Having an intraoral repair protocol and the proper materials handy will prepare your office for these incoming cases. Restorative dentistry is one of the first steps towards getting patients back to their healthy lives.
In this post, we’ll cover the basics of intraoral repair.
Gather Your Materials
First, you’ll need to gather your products and materials. Intraoral repair will require a few key products:
You can gather these materials from what you already have in your office and create a DIY kit using a tackle box or something similar.
BISCO also offers a dedicated Intraoral Repair Kit.
Understanding The Process
The process for repairing porcelain and metal restorations will be the same, however the protocols will be different depending upon the substrate.
Step 1: Mechanical retention
For metal/zirconia substrates: sandblast or bur roughening
For glass ceramic substrates: HF etch (make sure to read the instructions for etching times)
Refer to the IFU for etching times
Step 2: Chemical priming
For metal/zirconia substrates: organophosphate (MDP) containing primers
For glass ceramic substrates: Pure silane
Follow the correct protocol for the restoration substrate.
Isolation with a rubber dam
Prophylaxis of the restorative area
Metal/Zirconia = sandblast or bur roughening
Glass Ceramics = HF etch
Glass Ceramics = silane first
Metal/Zirconia = MDP containing primer
Apply a D/C opaquer to mask metal (if metal is exposed)
Note: This step not necessary for Zirconia
Apply a porcelain bonding resin or dental adhesive
Apply final restorative composite
