Lab Required Parts - Fixture Level Impression - Closed or Open Tray
Posted on 07/26/2011
While the implant systems may vary, the parts necessary for the lab complete a case are actually pretty standard. Here is a list of parts based on technique:
Implant Fixture Level Impression - Closed or Open Tray - 5 Required Parts
1. Impression Transfer Coping
2. Impression Transfer Coping Screw
3. Implant Replica (Analog)
4. Abutment (either metal, plastic with gold base, or zirconia)
5. Abutment Screw
These five parts are always required. There are some systems where the abutment is the impression coping (Bio Horizons) or the impression coping is attached to the final abutment (Implant Direct Replant), but the parts remain the same. If you can identify all these parts, the lab can proceed with the case.
Here is an explanation of the purpose of each part:
1. Impression Transfer Coping - used to transfer the position of the implant fixture in the mouth to the implant analog in the model.
2. Impression Coping Screw - used to secure the impression coping to the implant fixture in the mouth and to secure the impression coping to the implant analog in the impression (prior to pouring the model)
3. Implant Analog - A replica of the implant fixture from the mouth. After attaching the implant analog to the impression coping, the lab can pour a model which will secure the implant analog in stone to replicate the position of the implant fixture that is in the mouth.
4. Abutment - the final abutment that will be placed in the mouth to support the crown. If a cement retained crown is requested, a metal or zirconia abutment may be provided to the lab - which will be modified by the lab. If the doctor requests to make a custom abutment, or if the doctor wants to do a screw retained single crown, it is ideal to use a UCLA Plastic Abutment with a Gold Base.
5. Abutment Screw - This screw secures the abutment to the implant analog in the model. Some doctors may use this screw as the final screw to secure the abutment to the implant. However, it is recommended that doctors use a new virgin screw for the final screw.
