Conical Ball Attachments

GDT conical connection ball attachment aligned above the implant platform, showing the screw retained overdenture interface.

GDT Conical Ball Attachments provide a reliable, implant-retained overdenture solution based on a proven ball and cap retention mechanism. Designed to support daily function with controlled resilience, they help maintain stable prosthetic seating while allowing natural movement under load for improved patient comfort. With replaceable silicone caps that allow retention to be adjusted over time, this system supports predictable long-term performance in both partial and fully edentulous cases.

GDT Conical Ball Attachments are engineered to deliver predictable retention and stability for overdenture restorations, offering a reliable solution for partial and full edentulous cases. By incorporating a proven ball-and-cap retention mechanism, this system supports long-term function and improves patient satisfaction. The ball attachments connect directly to dental implants and utilize replaceable silicone caps to provide controlled flexibility, absorb functional movements, and maintain a secure prosthetic connection throughout daily wear.

Each GDT Conical Ball Attachment features a standardized Ø2.5mm ball head, engineered to offer multidirectional resilience and optimal pivoting under occlusal load. This allows the prosthesis to accommodate natural chewing dynamics while minimizing strain on the dental implants.

Compatible with NobelActive® conical connection, GDT Conical Ball Attachments are available in two platform sizes: Narrow Platform (NP) 3.5mm and Regular Platform (RP) 4.3-5.0mm, ensuring compatibility with a wide range of implant systems that follow this conical connection.

Engineered for Long-Term Clinical Performance

GDT Conical Ball Attachments are precision-engineered from Titanium Grade 5 (Ti-6Al-4V ELI), a medical-grade alloy known for its strength, biocompatibility, and resistance to corrosion. The Bal Attachment’s monoblock construction delivers structural integrity and reduces component fatigue over time. Each attachment is manufactured to tight tolerances, ensuring a reliable fit with implant fixtures and consistent performance under functional loads.

The system is designed for simplicity and durability, making it a practical choice in high-use cases where long-term retention and patient comfort are essential. The single-piece ball design eliminates weak points and helps streamline both placement and maintenance procedures.

Silicone Caps for Adjustable Retention

Retention strength within the GDT Conical Ball Attachment system is controlled by color-coded silicone caps, which are available in multiple retention levels to accommodate patient-specific requirements. These silicone caps serve as the primary retention interface, engaging the ball head of the attachment and securing the overdenture in place. Over time, as the caps experience wear, they can be easily replaced to maintain optimal retention force.

The available cap options include:

  • Yellow – Extra Soft – 0.5 kg (1.1 lbs) of retention
  • Pink – Soft – 0.9 kg (2.0 lbs) of retention
  • Clear – Standard – 1.3 kg (2.9 lbs) of retention
  • Black – No Retention Lab Cap – for laboratory use or non-retentive applications

This range allows dentists to customize prosthetic retention to individual functional needs and comfort thresholds, supporting a more patient-centered restorative outcome.

Prosthetic Adaptability Across Clinical Scenarios

GDT Conical Ball Attachments are ideal for supporting overdentures in a wide variety of clinical conditions, particularly where removable solutions are preferred due to anatomical, hygienic, or economic factors. The system is also highly effective in cases involving limited vertical restorative space, where alternative attachment systems may not be feasible. The conical geometry of the base ensures a tight fit within compatible implant platforms, minimizing micro-movement and ensuring a reliable connection.

Supporting Predictable Retention and Patient Comfort

GDT Conical Ball Attachments are designed to provide dentists with a reliable solution for securing overdentures in standard and challenging implant clinical cases. Their precision engineering, and flexible retention options make them a strong choice for maintaining long-term stability and patient comfort. Used in conventional overdenture workflows and complex restorative cases, our Conical Ball Attachments deliver lasting results supported by proven material integrity and thoughtful design.
