We present BIONIKA’s innovation, the new generation of abutments, the BIOPOZ bite registration heads, which have been created based on the idea of Rátonyi József dental technician. The latest product of BIONIKA Medline Orvostechnikai Kft., which is a novelty worldwide. This solution has filled the gap and created the possibility of precise bite registration also for implant dentures.
Bite registration heads on implant level
Bite registration tools are needed so that we can determine the meeting plane of the occlusal surface of the lower and upper teeth. In the case of a toothless mouth, multiple solutions can be found in dental practice. However, there was no adequate solution for cases regarding implants. Based on the idea of the dental technician, József Rátonyi, BIONIKA Medline Orvostechnikai Kft. has developed a simple, globally unique method and toolset aimed at this pivotal problem, for accurate bite adjustment in implant-based dentures. The essence of this solution is that the implants are equipped with a structure containing matching parts, which ensures the implant’s parallelism within broad boundaries. For the system to work even in the case of significant angular deviation (e.g. 60°/90°), we prefer the use of conical geometry. As a solution, we use an external conic abutment and a magnetic insert within the implant, and a cap part connected by a magnet with appropriate force. The magnetic connection ensures the simple movement, but safe position of the matching parts.
Selection of bite registration
The bite registration heads are available for any implantation system at BIONIKA. The head design is the same with every system in the cap area and differs only in its features with relation to the implant. That is, the head design is usually similar to a 60° Multi-Unit conical solution (also available in a 90° design), in which the upper Multi-Unit screw is replaced with a magnet. This ensures the secure positioning of the bite registration cap, and its simple removability at the same time. The bite registration heads are available to be either fastened directly into the implant (implant level) or placed on Multi-Unit heads (Multi-Unit level) appropriately to the usual applied dentures.
Process of bite registration
The bite registration heads are screwed into the implants. The bite registration caps are then placed on the bite registration heads. The caps are fixed magnetically.
1. In the consulting room, the doctor takes a precision imprint from the implants located in the jawbone and records the physiological bite height (centric tray).
2. In the lab, the samples are articulated on a mean, based on the centric tray register. This is followed by the placement of the bite registration heads and caps, where the registrant plate is built into the latter.
3. In the consulting room, the doctor screws the bite registration heads into the implant and the registrant plate is also attached. Registration is carried out (with a support pin), then the registrational plates are attached to each other.
4. The samples are articulated in the lab, which are based on the central relational position of the registrational plates.
