Individual grinding of the Mini gold bar abutment

Check

The abutment is customised using the denture set-up. Caution: The connecting interfaces with the implant must not be sandblasted or finished. The fit is predetermined according to industrial specifications.

Check that the construction is seated without any gaps and free of stresses (Sheffield test).

Bars

Trial fitting of frame

Fit the bar straight and flush between the Mini gold bar abutments using a parallel retainer if necessary. A minimum distance of approx. 2 – 3 mm from the gingiva must be maintained. Align the bar parallel to the occlusal plane in the physiologically most favourable position in accordance with the abutments and the contour of the alveolar ridge.

Trial fitting of the frame on the model and in situ with the set-up denture is recommended. For trial fitting of the prosthesis cut out the bar in the denture base.

Welding / soldering the connection

Completion / Integration

Follow the instructions of the laser supplier and the solder manufacturer. Laser welding is the option which should be preferred here. Incorrect welding / soldering can lead to mechanical failure, which may pose a health risk to the patient.

The denture is completed on the model after blocking out any undercuts around the female / male part. The dental technician completes the work as usual. The Mini prosthesis screw is used for final placement of the restoration in the patient’s mouth (torque: 25 Ncm) (tool: hexagon screwdriver 1.25 mm).
