Placement of implant with improper axial angulation

Surgical placement of the implant improperly can lead to a prosthetic rehabilitation that compromises esthetics and the distribution of loads. In cases when the available bone is less the best way is to graft the site and obtain an ideal biomechanical scenario. The use of implant in an angulated direction (to place the implant as dictated by bone and not the future restoration) leads to the creation of offset loads. Endosseous implants are best suited to distribute occlusal forces in an axial direction and the shear forces are highly damaging to the implant structure and supporting bone and causes implant failure and therefore any offaxial angulation should be limited to about 25 degrees.
