No more distorted impressions! Try the revolutionary solution!
Has it ever happened to you that an impression was distorted or collapsed during the impression-taking procedure? If so, it is time to discover the angled impression transfer copings that are indispensable for ideal impression taking — making your work simpler, faster, and more accurate. Learn the secret to precise, exact impression taking in the article below.
Impression-Taking Techniques
Impressions are taken using either the open-tray or the closed-tray technique. In the open-tray (direct) technique, the custom tray is removed from the mouth together with the impression transfer copings at the time of impression taking. By contrast, with the closed-tray (indirect) technique, the impression transfer copings placed into the implants remain in the mouth during the impression procedure.
The closed-tray technique is applicable in cases of partial edentulism, while the open-tray approach can be used for both partial and complete edentulism. Silicone- or polyether-based materials are typically used as impression materials.
Challenges in Using Impression Transfer Copings
Implants are generally not parallel to one another. With closed-tray impression transfer copings, it is common for the impression to become distorted or to collapse. Another significant problem arises when an open-tray impression transfer coping cannot be removed from the implant without distortion. Reinserting the three-piece impression transfer coping also frequently poses difficulties for clinicians. Experience shows that simultaneous single-phase and two-phase impression taking is not the most ideal solution either.
What Makes an Ideal Impression Transfer Coping?
The ideal impression transfer coping is parallelisable — meaning it does not distort the impression. It is also repositionable, making it suitable for two-stage, two-phase impressioning of natural teeth. The BIONIKA impression transfer copings, developed in collaboration with Dr. Áron Becsky, are considered ideal transfer copings: their 15°, 25°, and straight geometric configurations allow for a perfectly parallel axis alignment from which a closed-tray impression tray can be removed with ease. The end of the closed-tray impression transfer coping and the groove on it provide stable retention. The impression transfer copings have a depth of 13 mm, which is ideal — with sufficient care, they can be reinserted into the tray. Clinicians who have experienced the BIONIKA impression transfer copings exclusively use these, as they enable considerably simpler, faster, and more accurate work.
Size Range of BIONIKA Ideal Impression Transfer Copings
BIONIKA angle-correction impression transfer copings are available for all implant systems, including narrow, standard, and wide implant diameters. The angle-correction copings are available in 0°, 15°, and 25° angular offsets; however, a denser range of angular offsets can be provided upon request.
