The Directional Rings by Rhein 83 are precision accessories designed for use with Sphero Flex attachments and blocks in implant-retained overdenture systems. These colored rings are engineered to help dental professionals compensate for implant angulation and achieve a more accurate path of insertion during prosthetic rehabilitation.
This product is available in different angulations — 0°, 7°, and 14° — allowing clinicians and dental technicians to correct implant divergence when preparing the prosthetic structure. By selecting the appropriate ring, the technician can adjust the orientation of the attachment system and optimize the alignment of the overdenture.
Designed specifically for the Sphero Flex system, the Directional Rings contribute to the correct positioning of the attachment components and help improve the overall functionality and stability of implant-supported prostheses. Their color-coded design makes identification easy during both clinical and laboratory procedures, simplifying workflow and reducing the risk of errors.
Manufactured to the high precision standards of Rhein 83, these Directional Rings are an essential component for dental laboratories and clinicians working with Sphero Flex attachments, ensuring accurate alignment and predictable prosthetic outcomes.
