A Partial Palatal Coverage Overdenture Retained by Zygomatic Implants

Area of Science:

• Dental Implantology
• Prosthodontics
• Oral Rehabilitation

Background:

• Atrophic edentulous maxilla presents significant challenges for fixed prostheses.
• Fixed implant-supported prostheses require optimal implant placement, often difficult in atrophic ridges.
• Removable prostheses offer alternatives, utilizing fewer implants and anatomical support.

Purpose of the Study:

• To describe the fabrication of a partial palatal coverage overdenture.
• To demonstrate the use of zygomatic implants for retention in atrophic maxillae.
• To present a treatment option for complex cases of edentulism.

Main Methods:

• Fabrication of a partial palatal coverage overdenture.
• Utilizing zygomatic implants for support and retention.
• Clinical treatment protocol for rehabilitation.

Main Results:

• Successful fabrication of the overdenture.
• Stable retention achieved with zygomatic implants.
• Improved function and aesthetics for the patient.

Conclusions:

• Zygomatic implant-retained overdentures are a feasible treatment for atrophic edentulous maxillae.
• This approach simplifies rehabilitation in complex cases.
• Offers a predictable prosthetic solution for challenging implant arrangements.
