Ball Head Abutments are a proven, low-profile attachment system for implant-supported overdentures. The spherical ball design, combined with the included metal housing and replaceable black O-rings, allows for rotational and hinge movement while providing strong, consistent retention. The Aqua (3.5/4.0mm) platform is commonly used for 2–4 implant overdenture cases, delivering excellent stability, patient comfort, and simplified prosthetics.

• Compatible with Astra Tech OsseoSpeed TX implants – specifically the 3.5mm and 4.0mm diameters (Aqua color-coded Small connection)
• Ball Head Abutment design with standard 2.25mm ball diameter for secure overdenture retention using the included nylon-compatible matrices
• Complete kit includes: One Ball Head Abutment, one metal housing, and two black rubber O-rings – ready for immediate clinical use
• Medical-grade titanium construction provides excellent biocompatibility, strength, and long-term corrosion resistance for the abutment
• Available collar heights (1.0mm, 2.0mm, 3.0mm, 4.0mm, 5.5mm) for optimal soft tissue adaptation and emergence profile
• Precision machined for a tight, stable fit that minimizes micro-movement and supports reliable daily function
• Ideal for implant-retained overdentures – simple, cost-effective solution for edentulous patients seeking improved stability and comfort
• Cost-effective high-performance alternative to original Astra Tech overdenture abutments while maintaining full compatibility
• Easy maintenance – black rubber O-rings can be replaced chairside for consistent retention and patient satisfaction

2. How To Do An Overdenture Restoration Of Astra Compatible Implants Using Ball Head Abutments (Chairside Technique) 

Ball head abutment is a one piece abutment with a superior ball projection that is used with two or more implants to fixate dentures to implants in a fully edentulous arch. It comes with a metal housing and retentive rubber o-rings. Ball head abutments can be processed into the denture using pick-up chairside technique or laboratory technique.

• Ball head abutment comes as a kit which includes Metal Housing & Two Rubber O-Rings

• Requires additional purchase of BALL HEAD WRENCH for first time orders.
• Ball Head Wrench must be purchased separately.

Technical Considerations :

• A minimum inter-occlusal clearance of 6mm and cuff height is required.
• Implants must be relatively parallel to one another with less than 10 degree total divergence.
