Dental implant crowns are the final ‘tooth’ that the implant supports.

This will often be the last step in the implant process. As with crowns on natural teeth, there are a range of options and need to be assessed for the individual case.

Firstly, there are screw retained and cemented crowns.

For a screw retained crown, the crown is made with the implant abutment (the precision attachment that fits the implant) integrated into the crown.  The crown is then screwed to the top of the implant and the hole sealed with a temporary filling material.  For this to be achieved, the implant must be in a position that allows a favourable ‘screw hole’, in the occlusal surface for posterior teeth or on the palatal surface of anterior teeth.

A cement retrained crown, as the name implies is cemented into place.  In this case, the abutment is screwed onto the implant and the crown is cemented into place on the abutment.  While this can allow crowns to be placed on implants with non-ideal alignment, it is more difficult to remove the crown in cases where repairs to the crown are needed.
