Ribbond splinted bridge with 5 year follow up
Posted on March 02 2019
As per patient, bonded composite bridge is 12 years old. It was done intraoral using Ribbond as a fiber reinforcement. Bridge was holding strong until her grandchild bumped the pontic with his head.
Pontic is loose, but held in place by the intact Ribbond.
Look closely and you can see the Ribbond fibers at the mesial lingual of #8. Composite has chipped away, but the Ribbond is holding strong.
All caries removed from #7. Left with an apple core prep.
Wide band in place
Greater Curve "Wide" placed over #7.
Matrix cut back
Matrix has been cut back for access, and retainer secured with Triad Gel to provide stability.
Matrix in place
Matrix was held in place at the distal while my assistant light cured the first increment of flowable. This was necessary because the matrix at the contact opening would not lie up against the mesial of #6.
Look closely and you can see the blade indent of the composite instrument. Matrix is now sealed against the mesial of #6.
Filtek supreme Ultra dentin shade 3.5 provides the base.
A2 body is placed over the incisal 2/3's.
Initial cut back
Leave the matrix in place while doing the initial cut back. Cutting both stainless and composite will prevent accidental gouging.
Setup similar to tooth #7 with matrix cut back to provide access to the prep.
Alginate impression poured up with a polyvinyl model material. Gingiva and teeth poured with Mach-Slo and base made with Mega bite.
I use Mach-Slo (Parkell) to pour the teeth and gingiva. MegaBite (DenMat) for the base. MegaBite is hard like plaster and makes a solid base for the more flexible Mach-Slo.
Ribond fiber in place
Ribond fiber coated with flowable composite then light cured.
Dentin shade 3.5 placed against the Ribbond on the cervical 2/3's and sloped toward the palate.
A2 Body was placed over the incisal 2/3's. A stain line was painted into the depth of a groove made within the A2 body.
A2 Body was pushed together burying the stain line within the A2 composite.
Bridge try in
Don't obsess making the bridge perfect on the model. Make adjustments after the bridge is bonded. You can see that the incisal of the pontic is too long and some contouring will be needed.
Final Ribbond bonded bridge
I made this bridge over my lunch hour so patient could have bridge the same day. Sorry, forgot to take an incisal view.
5 years later
Case holding up well in spite of the patient's poor home care. This is how she presented to the office 5 years later. Wanted everyone to see photo before my hygienist cleaned her teeth.
I use this technique frequently for lower anteriors opposed by an upper denture. Much better than the patient dealing with a removable partial.
