    Area of Science:

    • Biomaterials Science
    • Dental Implantology
    • Prosthodontics

    Background:

    • Osseointegrated implants are crucial for replacing missing teeth.
    • Stress accumulation in the bone-fixture-prosthesis system can lead to implant failure.
    • Current prosthetic frameworks may present challenges in precise adaptation and stress distribution.

    Purpose of the Study:

    • To present a novel framework design for osseointegrated implant prostheses.
    • To detail the components and biomechanics of a direct assembly framework.
    • To highlight the advantages of this framework in terms of stress prevention and clinical technique.

    Main Methods:

    • Framework design incorporating components joined intraorally with cement.
    • Methodology allowing for precise framework adaptation to abutments (within 5 microns).
    • Discussion of component integration and biomechanical principles of direct assembly.

    Main Results:

    • The proposed framework design effectively prevents stress incorporation into the bone-fixture-prosthesis system.
    • Intraoral cement joining and precise adaptation (within 5 microns) are achieved.
    • A simplified laboratory and clinical technique is demonstrated.

    Conclusions:

    • The direct assembly framework offers a significant advancement in osseointegrated prosthodontics.
    • This design simplifies the prosthetic procedure, potentially improving clinical outcomes.
    • A streamlined four-appointment treatment protocol is feasible with this framework.
