Do you find bites to be more of a problem with implant cases than traditional crown and bridge? We sure do! This is due to a few factors. First, when taking a bite registration that utilizes the soft tissue or ridge as a stop, the inaccuracy can be quite large. This is caused by compression of the ridge during the impression procedure. This can displace the tissue by a millimeter or more. As a result, subsequent bite registrations do not fit the casts adequately.
In comparison, when taking a crown and bridge bite registration the registration and mounting is performed with bite material placed between the opposing teeth and the tooth preps. NO SOFT TISSUE CONTACT. As a result, the problems of proper vertical are reduced.
A friend of mine, Dene LeBeau, has developed the Implant Bite Post (IBP). The IBP is available in a long and short version and is compatible with many of the most common implant interfaces. This small but insightful innovation has dramatically reduced the problem of obtaining proper vertical for implant supported restorations. In addition, the IBP reduces the need to fabricate base plates and bite rims that require patients to return for an additional appointment just to obtain a bite registration (that is likely not as accurate). The bite procedure can routinely be accomplished on the same visit as the final impression. As a result of all the many advantages of the IBP, CAP now has a complete inventory of Implant Bite Posts for anyone looking to solve the common problems of bite registrations on implants.
You can see both maxillary and mandibular implants have been placed and there is no way to articulate this cases by hand.
