Bone grafting and sinus elevation are the two procedures most responsible for the difference between a quoted total and a final invoice. Both are frequently necessary, and both are frequently omitted from initial estimates.
Why bone volume determines feasibility
An implant requires sufficient bone in three dimensions to achieve primary stability and long-term support. Following tooth loss, alveolar bone resorbs progressively, with the greatest loss occurring in the first year.
Patients who lost teeth years or decades earlier therefore present far more frequently with insufficient volume, which is why grafting features so prominently in treatment planning for older patients.
Typical cost contribution
Bone grafting commonly adds $500 to $2,000 per site. Sinus elevation, required when pneumatisation of the maxillary sinus has reduced available height in the posterior maxilla, commonly adds $1,500 to $5,000 depending on whether a lateral or crestal approach is indicated.
Block grafting and more extensive reconstructive procedures exceed these ranges substantially.
Why this cannot be determined from a photograph
Panoramic radiography does not permit reliable assessment of bone width. Cone beam computed tomography is required to establish whether grafting is necessary and, if so, of what extent.
Any estimate provided without cross-sectional imaging is provisional by definition, and should be presented as such.
Planning implications
Where grafting is required, healing intervals of four to nine months are typical before implant placement or loading, which affects scheduling considerably for patients travelling for treatment.
Obtain cross-sectional imaging before accepting any implant quotation as final. It is the only basis on which grafting requirements, and therefore true cost and timeline, can be established.
