Impression Coping Transfer For Multi Unit 1.6 Abutment - Open Tray

The Impression Coping Transfer for Multi Unit 1.6 Abutment is used during open-tray impression procedures to accurately replicate the position, angulation, and height of the abutment in the working model. It is screwed into the abutment intraorally and remains fixed within the impression tray upon removal. This ensures a precise transfer of spatial data to the laboratory, enabling technicians to place the analog correctly and fabricate a well-fitting prosthetic restoration. Its role is especially important in complex or multi-unit restorations where accuracy is critical for long-term success.

We use stainless steel for this transfer due to its excellent strength, corrosion resistance, and dimensional stability. These properties make it ideal for enduring the mechanical stress and handling throughout impression taking and laboratory procedures. Stainless steel resists deformation during tray removal and model pouring, ensuring that the coping preserves its exact geometry. This reliability is essential for maintaining the accuracy of the prosthetic workflow and reducing potential errors during fabrication.

The open-tray, or pick-up, design allows the coping to remain locked inside the impression material when the tray is removed. This prevents any movement or repositioning of the coping post-removal, which is a common source of error in closed-tray techniques. By preserving the precise alignment of the coping, the open-tray method ensures an accurate and predictable transfer of the intraoral situation to the dental lab, leading to prosthetics that fit with minimal adjustment.

Before selecting the GDT Implants Impression Coping Transfer for Multi Unit 1.6 Abutment, clinicians should assess implant parallelism, arch span, multi unit type and soft tissue thickness. The open-tray design is particularly effective when implants are non-parallel or when visibility and access are limited. If vertical space is constrained or the angulation exceeds typical restorative allowances, using this coping can reduce the risk of impression distortion. Additionally, when high precision is required, such as in full-arch reconstructions, this coping provides a predictable and stable reference for prosthetic planning.
