The trepan burs 227A permit safe explantation of all implants with diameters of 2.5, 3.3, 4 and 5 mm and is available in four sizes.

What are the advantages of these trepan burs?

• The laser depth markings at 7, 10, 13 and 16 mm permit precise exposure of the implants to the required depth.

• The openings in the working area of the bur permit a better vision on the surgical site and furthermore facilitate ejection of the bone cylinders.

• The trepan burs made of stainless steel feature a high-efficiency toothing
specially designed for cutting bone and guarantee gentle treatment.

• The indication of the dimensions on the instrument shank enables easy identification of the four sizes.


Recommendations of use:

• Recommended speed: 800 –1000rpm

• To be used in the green contra-angle (reduction at least 10:1) under constant external cooling with sterile physiological saline solution.


1. Opening the mucosa

2. Exposing approx. 1– 2 mm of the upper part of the implant as guiding aid for the trepan bur

3. Explantation of the implant with trepan bur in an intermittent mode
applying constant external cooling

The implant can then be removed with extraction forceps performing a slight rotational movement.
