Pterygoid Implant as Abutment of Partial Fixed Dental Prosthesis

Supporting Patients with Defective Dental Bridges

Luis, a 52-year-old patient, came to us seeking replacement of a failing bridge #1-5. He had multiple previous dental restorations that had failed. Luis had become desperate to find a solution that would allow him to confidence to eat and speak properly as well as improve his comfort and appearance. He had maxillary sinus pneumatization and did not want to have a graft.

This challenging scenario was resolved by using some of the latest prosthodontic advancements: 

  • Utilization of pterygoid implants
  • Digital and castless workflow
  • Photogrammetry extraoral implant impressions
  • Design and manufacturing of monolithic zirconia component-less prostheses

Luis’s diagnosis included a complete prosthodontic evaluation involving CBCT scan, x-rays, photographic analysis, Intraoral Optical scanning, and a full oral examination. Luis’s was diagnosed as having a defective long-span bridge and failing abutment tooth #5 with pneumatization of his right maxillary sinus, making him an excellent candidate for a pterygoid implant.

  • Extraction of teeth #1 and 5 and the immediate placement of implants in positions: 1, 4, and 5.
  • Soft tissue contouring using a provisional fixed prosthesis.

Pterygoid Implant Treatment Outcome

The patient was pleased with the treatment outcome. During the procedure, minimal occlusal adjustments restricted to lateral movements were performed. Luis can finally eat and speak with confidence and comfort.

This case demonstrates the use of recent technological advances in the field of implant prosthodontics that allows for expedited treatment and improved treatment outcomes for patient and providers.

As a Prosthodontist, I often coordinate with a patient’s general dentist and other dental specialists that they’ve seen.

If you have a patient in a similar situation and would like to team up for either the surgical or surgical and restorative planning of a similar case we would be happy to assist you.

How can a Certified Prosthodontist assist you and your dental team?

We specialize in the treatment of complex cases, usually involving several procedures over months of care. The next time you see a challenging case, please feel free to call us and we can discuss treatment planning or help you with any part of the treatment. Our goal is to be a resource for your office by helping manage difficult and time-consuming procedures, restoring the function and esthetics that each patient desires, then referring them back to your office for their ongoing care.

If you have a patient with several missing, broken, or severely worn teeth — or patients that are unhappy with their defective bridge — they may be a candidate for oral rehabilitation with the assistance of a Prosthodontist.
