Esthetic considerations in anterior single-tooth replacement.

Anterior single-tooth replacement is the ultimate challenge facing the prosthodontist or the restorative dentist. Use of dental implants as a modality of treatment has overcome the disadvantages of conventional restorative techniques. Implantologists aim at creating an implant-supported restoration that replicates natural teeth.

In addition, it discusses one of the problems in esthetic implant dentistry, prosthetic-driven implant placement versus available-bone-driven implant placement.
