Precision attachments are retention units milled out of alloy. They have male and female parts that fit together with tolerances of 10 microns.

It is important to consult with the patient about the cost of using precision attachments in both fixed and removable prosthodontics. The patient needs to understand the inherent added costs of crown work required for these cases.


The dentist was approached by a patient for fixed replacement of the missing teeth in the upper right quadrant. Implants or a removable appliance were discussed as options but were rejected.

Preliminary impressions were made and the casts mounted on a semi-adjustable articulator with the pre-established vertical dimension.

A diagnostic wax-up was completed and the bridge designed. For more information on this Case study, please download the document above.
