An update on CAD-CAM usage for removable partial denture fabrication: A systematic review.

Area of Science:

• Dental Technology
• Prosthodontics
• Biomaterials Engineering

Background:

• Removable partial denture (RPD) framework fabrication traditionally relies on manual techniques.
• Assessing the accuracy and clinical efficacy of Computer-Aided Design and Computer-Aided Manufacturing (CAD-CAM) systems for RPDs is crucial for dental practitioners.
• Existing data suggest potential benefits of CAD-CAM in RPD fabrication, including improved fit and patient outcomes.

Purpose of the Study:

• To evaluate the accuracy of CAD-CAM systems in fabricating RPD frameworks in comparison to conventional methods.
• To highlight the key components and technologies influencing the success of CAD-CAM fabricated RPD frameworks.
• To identify areas for future research regarding the long-term clinical performance of CAD-CAM in RPD fabrication.

Main Methods:

• Comparative analysis of RPD frameworks fabricated using CAD-CAM versus conventional methods.
• Review of literature on digital impression techniques, CAD software, and additive manufacturing (milling/3D printing) for RPDs.
• Synthesis of current data on fit, adaptation, and clinical outcomes.

Main Results:

• CAD-CAM systems demonstrate superior fit and adaptation of RPD frameworks compared to conventional fabrication.
• Successful CAD-CAM fabrication depends on accurate digital impressions, advanced CAD software, and precise milling or 3D printing.
• Improved fit may lead to fewer post-insertion adjustments and enhanced patient satisfaction.

Conclusions:

• CAD-CAM technology presents a promising advancement for the fabrication of RPD frameworks.
• Further clinical research is necessary to validate the long-term efficacy and address limitations of CAD-CAM systems in RPD production.
• The integration of digital workflows in prosthodontics holds significant potential for improving treatment outcomes.
