Design concepts of a removable partial dental prosthesis with implant-supported abutments

Area of Science:

• Dentistry
• Prosthodontics
• Dental Implantology

Background:

• Severe anterior maxillary ridge defects and pneumatized sinuses pose significant restorative challenges.
• Patient preference for minimally invasive procedures limited traditional surgical interventions.
• Integrating fixed and removable prosthodontic principles offers a viable alternative for complex cases.

Observation:

• A rotation-path partial removable dental prosthesis combined with implant-supported abutments was employed.
• Standard clasp designs required modification due to direct bone-to-implant contact with abutments.
• Patient-specific limitations and preferences guided treatment modality selection.

Findings:

• The modified prosthesis design successfully addressed the severe anterior maxillary ridge defect and pneumatized sinuses.
• Integration of removable prosthesis elements with implant abutments yielded a stable and functional restoration.
• Direct bone-to-implant contact necessitated specific adjustments to the prosthetic clasp design.

Implications:

• This case demonstrates a successful, less invasive approach to restoring complex maxillary defects.
• Modified prosthetic designs can overcome challenges posed by implant abutments in removable partial dentures.
• Minimally invasive prosthodontic solutions can achieve favorable esthetic and functional outcomes for patients.
