When a patient is interested in having implant therapy to replace any teeth in the esthetic zone (especially in the premaxilla), I get a sudden shiver down my spine. Completing the treatment is never the problem, but attaining an esthetic result is always a challenge. There are many items that must be considered on the … Read more
In the past, treatment planning for implant dentistry was primarily driven by the existing bone volume in the edentulous site. As a consequence, distal cantilevers were often extended from anterior implants to support a full arch implant prosthesis, rather than performing bone augmentation.
