SUBPERIOSTEAL IMPLANTS

Patient-Specific Maxillary and Mandibular Subperiosteal Implants

Subperiosteal prostheses are a type of dental implant that, unlike conventional endosteal implants, are not placed inside the jawbone. Instead, they are positioned on top of the jawbone and beneath the gum tissue using a custom-designed frame. These prostheses are secured with small screws at different points of the jaw and gradually become stable as new bone forms around and over the frame. They are typically recommended for patients who, due to severe jawbone resorption or other conditions, are not suitable candidates for traditional intraosseous dental implants.

◀ Placement of multiple abutments within a very short time
◀ Faster dental restoration compared to bone augmentation and grafting methods
◀ Geometric adaptation to the bone surface with uniform load distribution
◀ Roughened surfaces at the bone–implant interface to accelerate the process of osseointegration

Despite being introduced several decades ago, subperiosteal prostheses were only used in specific cases due to the complexity of their fabrication.

In the past decade, with the advent of 3D printing technology and the ability to manufacture medical prostheses from Grade 23 titanium alloy, the use of these prostheses has become more widespread.

Bonash Medical subperiosteal prostheses are custom-designed and manufactured for each patient according to the unique anatomy of their jawbone. The prosthesis is placed directly on the bone without the need for manual shaping, making the placement process easier and faster.

Furthermore, the positioning of the abutments—including their location, height, geometry, and angulation—is designed according to the prosthodontist’s requirements. As a result, the final outcome is far more precise, durable, and stable.
