Single implants and their restoration
Osseointegrated implants not only have become routinely recommended for replacing single missing teeth but the preferred treatment modality. This treatment planning choice is due, in part, to the high 5-year survival rate1 of single implants (96.8%) and their associated single crowns (94.5%). However, some mechanical and biologic complications can arise with dental implants. For example, a 2011 systematic review of implant single crowns determined that abutment screw loosening ranged from 1-10% in the nine included studies and occurred with both external and internal connection implants. Other reported complications have included esthetic deficits, mucosal inflammation, fistulas, abutment screw fracture, implant loss, and implant fracture. While such complications have typically been relatively infrequent, every effort should be made to minimize complications as much as possible.
