In my office, the broken implant body was removed successfully. 4 months later, a new implant was placed surgically on tooth #30. Then, another 4 months later, a new crown was fabricated and seated.
When seating crowns, Interproximal Relief (IR) should be restored as it exists in natural dentition. IR is the passive contact or microscopic clearance between teeth when they are in rest position. In my experiments, this clearance cannot be properly detected with floss, because floss is too thick and an inaccurate measuring device.
A 93 year old female patient came in with tooth #25 very loose. X-rays showed #25 had no bony support and 23, 24 and 26 were also loose with minimum bony support. Splinting teeth 23, 24, 25, and 26 was recommended. To make the splinting solid, but to avoid leaving an empty center around the contact point, which weakens the splinting, the ContacEZ White Strip was used to spread composite masonry from facial to lingual.
Before taking crown impressions, any sharp edges on the proximal surfaces of the adjacent teeth are smoothened and polished with ContacEZ Restorative Strips. The proximal surfaces of adjacent teeth are also cleaned, contoured, and polished in anticipation of the new, properly fabricated crown. This procedure helps ensure the replacement crown fits perfectly and comfortably for the patient.
Ensuring ideal contact adjustment on implant-supported crowns is a task that needs to be approached methodically. Tightening the crown too rapidly can make it nearly impossible to access the interproximal space, while adjusting while the crown is too loose is ineffective and potentially inaccurate. With a little patience and a pair of ContacEZ Strips, however, you can consistently achieve the best results simply and easily.
Seating crowns in posterior areas can be exceptionally difficult. In addition to limited accessibility, it is also hard to visually confirm each step of the process. X-rays taken both after proximal contact adjustment and again after cementation can be a vital tool in ensuring both complete marginal seating and the removal of all excess cement.
For composite fillings, the primary retention of your restoration often depends on removing any existing biofilm from the area to ensure a strong micromechanical bond between the prepared tooth and the resin. With the ContacEZ Copper Narrow Strip and Black Diamond Strip, preparing a fresh interproximal surface for fillings has never been easier.
