The usefulness of splinting of severely loosened teeth in advanced periodontitis has been discussed extensively, both positively and negatively. Retention of patients' own teeth through the aid of this simple and inexpensive resin composite splint provides a satisfactory solution for many affected patients. The fabrication and placement techniques for splints for the anterior and posterior regions are described, as are additional indications for such splints, which are fabricated from resin composite and glass fiber bundles. Such splinting can be provided even for severely loosened, periodontally diseased teeth without danger of intraoperative tooth loss. Long-term retention of such teeth can be ensured only through a risk-oriented postoperative program of oral hygiene and regular examination of the splint.
