Saving an Integrated Implant by Treating it as a Cast Post and Core by Combining Medit i700 Intra-Oral Scan with a Physical Impression of fixture’s Internal Shape

This implant was initially placed at the crest of the ridge in 2012.  its placement did not allow proper emergence profile and subsequently lost bone around the head of the implant by 2015.  The lack of blood flow to the crest of the bone at the cortical plate certainly could have contributed to its demise.  By 2015, the bacteria trap forced a new restoration to be placed which also ultimately lead to chronic inflammation due to improper contours.  The implant itself was well integrated and the decision was made to remove the top 3-5 mm of the implant and treat it as a cast post and core.

You can see how the Medit i700 was used to mix intra-oral scans with a PVS impression to capture the fixture.  Advanced users can utilize the stl of the implant itself to fabricate a post and core digitally.

The designed restoration was then sent to Burbank Dental Lab and it was milled out of wax and then cast to metal
