Single implants and their restoration
A dental implant is a type of therapy that offers patients an excellent means of replacing a tooth and restore both function and esthetics. However, the process is somewhat complex and, therefore, it requires more advanced planning than many traditional restorative procedures. In the area of esthetics, the following is a list of several factors that can strongly influence, either positively or negatively, the appearance of the final outcome.

Preservation of the peri-implant hard and soft tissues is an important aspect of the final esthetic result achieved with a single implant and its crown. Therefore, it is important to understand the biologic environment and the many factors that can enhance or detract from preservation when an implant is immediately placed into an extraction socket and a provisional crown attached to the implant.

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.
