A Technique to Obtain and Transfer Jaw Relation Records from Conventional Complete Denture to Implant-Supported Complete Denture.
Implant-supported or retained complete dentures are increasingly accepted as an alternative to conventional dentures for the oral rehabilitation of edentulous patients.1-4 In most
clinical situations, there exists a transitional period when patients need to wear conventional
complete dentures while waiting for the osseointegration of dental implants. These transitional
complete dentures can greatly facilitate the establishment of optimized jaw relation. However,
it remains a challenge for clinicians to accurately and efficiently transfer the established jaw
relation obtained with these conventional complete dentures to implant-supported prostheses.
Several reports have described the use of duplicate dentures to transfer vertical dimension of
occlusion at the centric relation position to fabricate the final implant-supported prostheses.
In all these reports, an additional duplication step is required, during which inaccuracy might
be introduced. A technique was recently reported to transfer jaw relation with an existing denture.9 In this technique, the intaglio surface of the denture must be relieved to accommodate the
autopolymerization of acrylic resin or a rigid vinyl polysiloxane impression material around the
healing abutments. However, the success of this approach relies heavily on the accurate seating
of the denture on the cast as in patient’s mouth, which is soft and resilient. Thus, precise seating
and transfer of dimensions is not always easily achievable.
The technique described below can aid clinicians to accurately and conveniently transfer the established jaw relation information from the conventional complete denture to the implant-supported complete denture. With this technique, no duplication of denture or mounting
the existing denture is necessary. However, this technique does require proper distribution of
implants to achieve desirable stability.
