TRI-NEX Co-Axis Dental Implants

TRI-NEX Co-Axis Implants offer clinicians a unique blend of implant and connection design features for simplified treatment with aesthetic outcomes. The innovative, first of its kind, Co-Axis Implant features 12° Subcrestal Angle Correction allowing clinicians to use the patients’ existing bone while maintaining the restorative platform at an angle that ensures optimal aesthetics.


The anatomic limitations of the anterior maxilla often require either tilting of the implant or a grafting procedure. This is also true when vital structures such as the maxillary sinus or the mental foramen limit accessibility. The resulting implant angulation often necessitates a severe angle correction at the prosthetic level with either a cement-retained restoration or using angled abutments. This can lead to potential esthetic and/or soft tissue complications.

The Southern Innovation

The TRI-NEX Co-Axis Implant interface features a tri-lobe hex drive connection with an additional internal hexagon. These features place the primary driving forces for implant insertion onto the hex, protecting the integrity of the lobes for prosthetic fit during restorative procedures. The coronal walls are also reinforced and beveled which further strengthens the walls of the implant and provides forced “platform switching” for prosthetic components. With the TRI-NEX Co-Axis Implant interface you can be sure of: Tactile sensibility/rigidity, up to 100Ncm torque values, and primary implant stability with an implant thread design suitable for high insertion torque while potentially limiting bone necrosis.

The TRI-NEX Co-Axis Implant Design also exhibits a 12° Subcrestal Angle Correction feature where optimal use of the patients’ available bone is achieved, while simultaneously allowing the restorative platform to emerge at the correct aesthetic angle without the use of an angled abutment, freeing up valuable restorative space. The implant body is tapered for better primary stability with immediate placement in extraction sockets and the implant surface is roughened along the entire length of the implant.

With TRI-NEX Co-Axis Implants clinicians can be confident in their implant choice by successfully negotiating problematic anatomical constraints, without sacrificing the ease, quality and appearance of prosthetic restorations.
