Stud attachments

Definition

A system where the patrix component is attached to the implant and the matrix is housed within the denture base.

Indications

The placement of a stud attachment is one of personal choice. The indications for its use are the same as for that of bars and magnets.

Advantages

The size of the attachment is smaller than a bar and therefore less room is required in the denture base. This may be of great benefit in a case where interocclusal clearance is limited.

Disadvantages

• The resilient ‘washers’ or ‘O’ rings perish with time and need to be replaced.

• They provide less retention than that of a bar.

Procedure

The patrix is attached to the implant and the matrix is placed within the denture base either at the processing stage or by using a direct technique at the chairside.
