GDT Ball Attachments offer a reliable solution for securing partial or full overdentures in edentulous cases. They provide a secure and stable connection between dentures and dental implants, featuring a Ø2.5mm ball-shaped connection. Available in straight, 18°, 30°, and 40° angulations, they help correct implant divergences of up to 90°, supporting ideal parallelism and long-term prosthetic success.

GDT Ball Attachments offer a trusted, practical solution for securing overdentures, for partial or full restorations. This system has proven its reliability, ease of use, and patient comfort over time. The ball attachments are inserted directly into dental implants and connect to the dentures through a silicone caps system. The caps absorb natural movements during daily function, improving denture stability and patient satisfaction while maintaining a secure, long-lasting fit.

Featuring a universal Ø2.5mm ball diameter, these attachments deliver excellent pivoting capabilities. This is especially beneficial for supporting natural chewing motions and for managing minor implant divergence. In cases where dental implants are placed at challenging angles, we recommend our specially engineered angulated ball attachments.

Angulated Design Ball Attachments

Our angulated ball attachments are engineered to meet the needs of challenging clinical procedures. Available in 18°, 30°, and 40° angles, they allow for the correction of implant divergences of up to 90° in all directions, helping to achieve ideal parallelism for prosthetic success. This range expands the possibilities for overdenture treatment planning, offering a high degree of flexibility.

Biocompatible and Aesthetic Solution for Overdentures

GDT ball attachments are manufactured from Titanium Grade 5 (Ti-6Al-4V ELI), ensuring outstanding biocompatibility and long-term durability. Thanks to their self-positioning mechanism, they help maintain denture stability with minimal maintenance over extended periods. Our ball attachment’s body design enables it to remain hidden within the gingiva, supporting a highly aesthetic and discreet restoration outcome.

Reliable Long-Term Performance

GDT ball attachments offer convenience for patients and dental professionals. After denture placement, ongoing maintenance is straightforward and can often be managed independently by the patient, reducing the need for frequent dental visits. Available with internal hex 2.42mm and slim platform internal hex 2.0mm connections, our ball attachments are compatible with a wide range of leading implant systems on the market today.

Silicone Caps for Customized Retention

Silicone caps are a critical component of the ball attachment system, determining the denture’s retention strength. With regular use, these caps may gradually wear out and should be replaced periodically to maintain optimal performance and stability.

At GDT Dental Implants, we offer a full range of silicone caps designed to accommodate varying patient needs and clinical requirements. Our options include Extra Soft, Soft, Standard, and No Retention Lab silicone caps, each providing a specific retention force: Extra Soft offers 0.5 kg (1.1 lbs) of retention, Soft provides 0.9 kg (2.0 lbs), and Standard provides 1.3 kg (2.9 lbs) of retention force.

This wide selection allows for retention control, offering the flexibility to customize retention levels for maximum comfort and functionality.

GDT ball attachments continue to offer a reliable, efficient, and aesthetic solution for modern overdenture restorations, supported by a decade of proven clinical success and continuous innovation.
