Temporaries Over Implants
Posted on 10/06/2011
Among the more popular indications for lab fabricated temporaries is for use over implants. Many large implant cases require long term provisionalization (six months to a year) to allow for tissue healing.
The implant supported temporary is different from the standard temporary because it requires implant parts. Most implant companies make temporary abutments either out of plastic or low grade titanium. These parts are less expensive than final abutments, but still add a significant cost to the case. As a result, some doctors decide to fabricate the final abutments with the temporary bridge. The danger with using final abutments is that as the tissue heals from the surgery, it tends often to grow over the abutment margin requiring further tissue reconstruction. Additionally, if the final working model is made using a direct impression of the abutments (so the stone cast is a replica of what is in the mouth rather than the original abutments), restoration fit will not be as snug.
We recommend to use low grade titanium temporary abutments rather than plastic temporary abutments - as the plastic are prone to breakage with deep bites or excesssive lateral excursions.
