Resorbable fixation using poly-L-lactic acid/polyglycolic acid copolymer plates and screws is effective for maxillary surgery. This biocompatible alternative offers advantages over traditional metallic devices in orthognathic and preprosthetic procedures.

Area of Science:

  • Craniofacial surgery
  • Biomaterials science
  • Orthognathic surgery

Background:

  • Metallic plates and screws are standard for facial skeleton stabilization but have drawbacks.
  • Biocompatible, absorbable fixation systems offer potential advantages.
  • Resorbable materials have been explored for various osteotomies, but documentation in preprosthetic surgery is limited.

Purpose of the Study:

  • To report a 5-year experience with resorbable fixation in superior maxilla surgery.
  • To evaluate the use of resorbable plates and screws in orthognathic and preprosthetic procedures.
  • To discuss the surgical technique, usefulness, and advantages of resorbable fixation.

Main Methods:

  • Utilized plates and screws made of an 82% poly-L-lactic acid/18% polyglycolic acid copolymer (PLLA-PGA).

  • Included 50 orthognathic and 5 preprosthetic procedures of the upper jaws.
  • All cases involved Le Fort I osteotomies.

    • Main Results:

    • Operations were performed without complications.
    • Follow-up ranged from 6 months to 5 years.
    • One patient experienced a localized infection that resolved with antibiotics.

    Conclusions:

    • Resorbable fixation is adequate for maxillary surgery.
    • The PLLA-PGA copolymer demonstrates efficacy in cranio-maxillofacial applications.
    • This study supports the use of resorbable materials as a viable alternative to metallic fixation.
