This is a premium fixed-removable combined dental restoration, composed of a fixed bridge with male ball attachments and a removable cast metal framework fitted with female cap inserts. It relies on concealed ball-cap interlocking for retention, avoiding visible clasps, delivering both stable chewing performance and easy cleaning for complex partially edentulous cases.

• Superior Aesthetics: No exposed metal clasps. The retention mechanism is concealed internally for a natural smile, ideal for anterior restorations.
• Stable Retention & High Masticatory Efficiency: Mechanical locking of ball-cap attachments prevents wobbling or lifting during chewing, with well-distributed occlusal force and far better chewing performance than ordinary acrylic dentures.
• Abutment Protection: Vertical insertion and removal generate minimal lateral torque on abutments, lowering the risk of loosening and damage. Gaps around the ball facilitate cleaning and reduce secondary caries.
• Thin & Comfortable Framework: High-strength cast metal allows slim framework design, less bulk and fewer foreign-body sensations compared to full acrylic bases.
• Adjustable Retention & Easy Repair: Retention force can be adjusted by replacing nylon caps of different retention grades. Worn caps can be replaced separately without remaking the whole prosthesis, controlling long-term maintenance cost.
• Excellent Biocompatibility: Made of medical-grade cobalt-chromium alloy or pure titanium, corrosion-resistant with low oral allergy risk.

Customized digitally via CAD/CAM according to individual patient impressions.

1. For patients with a small number of healthy remaining abutments and multiple missing teeth, who refuse full dentures and cannot receive implant treatment.
2. Anterior edentulous cases with high aesthetic demand and rejection of visible clasps.
3. Complex partially edentulous restorations requiring fixed-removable combined design to distribute occlusal load.
4. Also compatible with implant abutment version: implant-supported fixed bridge paired with ball-cap metal framework overdenture.
