Strategies to Achieve Passive Implant Frameworks

Current literature tells us that it isn’t possible to achieve a truly “passive” framework that splints multiple implants.  No matter what techniques or materials are used, there will always be some measurable stress or strain created.  It is known that framework misfits can cause screw breakage as well as component fracture but it’s effect on the supporting bone is still something of a mystery.  Some researchers feel that the bone can remodel in response to an ill fitting framework but the amount that can be tolerated isn’t quantifiable. Best practice procedures tell us that we should strive for frames that show no clinical or radiographic marginal opening, so it is important to review some simple ways to control clinical and laboratory generated errors.
