Bone is assessed in three dimensions
Height alone is not enough. Width, density and the volume required around the implant matter, as do the positions of the sinus and nerve canal. Imaging helps the clinician select a safe position and restorative direction.
Augmentation may or may not be required
Local grafting may be considered for smaller deficiencies, while larger defects can require staged augmentation. In the posterior upper jaw, sinus elevation may also be discussed. The appropriate technique and timing vary by case.
Alternative plans are possible
The solution is not always a large graft. Implant position, number, dimensions, prosthetic design and the condition of remaining teeth can create different options. The aim is a maintainable restoration supported by a biologically sound plan.
