Monolithic CAD/CAM Implant-Retained Overdentures: A Solution for Limited Restorative Space

Area of Science:

• Dental prosthetics
• Digital dentistry
• Biomaterials engineering

Background:

• Conventional implant-retained overdentures typically require 9-12 mm of vertical restorative space.
• Limited vertical restorative space presents a significant challenge in prosthetic rehabilitation.
• Patient-specific anatomical constraints necessitate innovative treatment approaches.

Observation:

• A patient presented with a severe limitation in vertical restorative space, measuring only 6 mm.
• Traditional prosthetic solutions were deemed unsuitable due to the restricted space.
• The need for a functional and esthetically pleasing overdenture was paramount.

Findings:

• Computer-aided design and computer-aided manufacturing (CAD/CAM) technology was employed to fabricate an implant-retained monolithic overdenture.
• The CAD/CAM workflow enabled precise design and manufacturing of the prosthesis within the limited vertical space.
• The fabricated monolithic overdenture successfully addressed both functional and esthetic requirements.

Implications:

• CAD/CAM technology offers a viable solution for complex prosthetic cases with limited vertical restorative space.
• This approach expands treatment possibilities for patients previously considered challenging for implant overdentures.
• The integration of digital dentistry enhances predictability and patient outcomes in restorative dentistry.
