Prosthodontic Criteria for Maxillary Immediate Occlusal Loading
Now online in the Journal of Prosthodontics, a report of a new classification system for immediate maxillary rehabilitation co-authored by ACP Fellow, Carl Drago, DDS, MS, FACP.
In order to provide patients with immediate full arch fixed implant-supported provisional prostheses, clinicians need to satisfy two broad parameters. One parameter is placing multiple implants throughout the arch with high levels of primary stability. The other is positioning the appropriate number of implants with satisfactory anterior/posterior (A/P) spreads, short posterior cantilevered segments, and fabricating passive fitting rigid prostheses.
Classification systems exist for edentulous maxillae but they do not include specifics regarding posterior implant placement. The available literature regarding current classification systems was reviewed and the benefits and limitations of each system were evaluated.
This article proposes a new classification system where the rationale was to show clinicians that when a certain amount of bone remains in the posterior maxilla, there are specific implants designed to maximize primary stability. High implant primary stability is required for rehabilitation with immediate fixed implant-supported provisional prostheses. The proposed classification system assists clinicians in understanding what implant geometry is available and can be expected to achieve the requisite primary stability for immediate occlusal loading based on the available bone in the posterior maxillary molar zone.
