Prosthetic rehabilitation of partially edentulous bruxing patients using dental implants

الملخص EN

Bruxism is a potential risk factor for implants and superstructures.

It increases the magnitude and duration of the force, changes its direction, and often increases its shear component.

In this study 31 root form implants were installed in the lower jaws of 4 partially edentulous bruxing patients according to the 2-stage surgical protocol to support ceramometal crowns.

Implants size, number, and distribution as well as occlusal design and night guards were considered in an attempt to keep stress factors within physiologic limits.

Maxillary arches were restored with overlay removable partial dentures.

Patients were followed-up for two years.

Each time, the restorations were retrieved, abutments checked and refastened if needed, and then standard periapical radiographs were made.

During the follow-up period, no component fracture was recorded.

Fixtures showed normal radiographic marginal bone reaction compared to that recorded in literature for non bruxer patients.
