Area of Science:

  • Dental Prosthetics
  • Implantology
  • Biomaterials

Background:

  • Implant-supported maxillary anterior fixed-detachable prostheses often include gingival flanges for esthetics and phonetics.
  • These flanges can hinder patient access for effective oral hygiene.
  • Current designs necessitate professional removal, complicating patient maintenance.

Purpose of the Study:

  • To introduce a novel two-piece, fixed-detachable prosthesis design for implant-supported maxillary anterior restorations.
  • To enhance patient accessibility for oral hygiene maintenance.
  • To describe the fabrication procedures for this innovative prosthesis.

Main Methods:

  • Development of a two-piece prosthesis: a substructure and a removable superstructure.
  • Substructure secured with conventional set screws, designed for hygiene access.

Related Experiment Videos

  • Superstructure attached via precision attachments, removable by the patient.

    • Main Results:

    • The two-piece design facilitates patient removal of the superstructure for routine cleaning.
    • The substructure's contouring allows for improved oral hygiene access.
    • The superstructure can be fabricated to meet esthetic and phonetic requirements.

    Conclusions:

    • This precision attachment-retained, implant-supported prosthesis offers a viable solution for improved patient oral hygiene.
    • The design overcomes the cleaning access limitations of traditional fixed-detachable prostheses.
    • It provides a balance between esthetics, phonetics, and patient maintainability.
