Immediate Load Implant Prosthesis - Hybrid

Full arch implant dentistry is being marketed heavily in todays dental world.  When properly planned and executed by highly trained dentists full arch implant dentistry can provide an exceptional alternative to dentures.   The example below illustrates the concept marketed as "teeth in a day", "all on four" or "all on five."   This concept is best described as the process of receiving a esthetic replacement of one's teeth with a temporary set of teeth that attaches to implants the same day they are surgically inserted in one's jaw bone.

Full Arch Implant Prostheses

Zurick Bridge (Zirconia substructure with pressed eMax crowns)

Description: Full arch or partial arch implant prosthesis.  Allows for a very esthetic replacement of both teeth and gingival tissue.  Requires 4 or more implants.  Requires about 10 mm of interocclusal space (top of the implant platform to the occlusal plane).  Fulfills a need to replace missing gingival height.

Advantages: esthetics tooth replacement, full arch tooth replacement, correction of implant angulation discrepancy, excellent function, replacement of lost gingival tissue, force distribution, implant splinting, ease of crown replacement if damaged in the future

Disadvantages: cost, possible future maintenance or repair costs, more difficult access to implant screws if needed in the future
