Dental implants and bar
A type of restoration where two to four implants are commonly placed in the edentulous arches and linked by a bar connector.
An edentulous patient who has problems with the retention of complete dentures due to an inadequate ridge form.
• The prosthetic treatment is straightforward. Therefore there is reduced time and expense when compared to other types of implant reconstruction.
• Fewer implants are required than for fixed implant prostheses and therefore treatment can be performed even if the bone availability is severely reduced.
• A removable prosthesis can compensate for defects in the ridge form as well as providing lip support.
• The patient’s oral hygiene is simpler than for fixed implant prosthesis.
• The load is equally distributed between the implant fixtures.
• Patients may object because the prosthesis is still removable.
• The prosthesis is mucosal borne and therefore regular checks are required for relining.
• The patient is still wearing a removable prosthesis and therefore the biting force and chewing efficiency is not that of a dentate individual.
1. Impressions are taken of the fixtures and then either a direct or indirect technique is used to construct the bar.
2. This is then fabricated and tried in the mouth.
3. The overdenture is constructed in the normal manner and the clip is placed at the processing stage.
