What an oral and maxillofacial surgeon actually does

Oral and maxillofacial surgery is the branch of dentistry concerned with the jaw, the facial skeleton and the tissues around them. It is a surgical specialty: the work is done in bone and soft tissue rather than on the visible surface of a tooth.

For implant patients this matters more than it first appears. An implant is a titanium root placed into the jaw, and whether it holds for decades depends on decisions made before anything cosmetic is fitted — how much bone is available, where the nerve and sinus sit, the angle and depth of placement, and whether the site needs building up first.

That is why the surgical and the cosmetic stages at Dentfix are done by different specialists. The surgeon places the foundation; the prosthodontist designs and fits what sits on top of it.

Frequently asked questions

Who performs the implant surgery at Dentfix?+
The surgical stages — placing implants, All-on-4 or All-on-6, and zygomatic implants — are carried out by our oral and maxillofacial surgeon, Dr. Siavash Abbasgholizadeh. The crowns and bridges fitted on top are prosthetic work, handled by our prosthodontists. Which specialists your case involves is set out in your treatment plan before you travel.
Why does it matter that a surgeon places the implant rather than a general dentist?+
Implant placement is bone surgery. The position, angle and depth determine whether the implant integrates and how the final teeth will load and function, and the site sits close to the sinus and the nerve. A maxillofacial surgeon is trained specifically in operating in that anatomy, including the grafting and sinus procedures needed when bone is insufficient.
I have been told I do not have enough bone for implants. Is that final?+
Often it is not. Insufficient bone can frequently be addressed with grafting or a sinus lift, and where the upper jaw is severely resorbed, zygomatic implants anchor into the cheekbone instead — a route that treats many patients who have been told elsewhere that implants are not possible. It is assessed from your CT scan.
Will Dr. Siavash handle my whole treatment?+
Usually not, and that is deliberate. A full case commonly passes from the surgeon who places the implants to the prosthodontist who designs and fits the teeth, because those are genuinely different specialties. What stays constant is your coordinator, from your first message to your last appointment.
How long after surgery before the final teeth are fitted?+
Implants generally need two to four months to integrate with the bone before the final crown or bridge is fitted, which is why most implant cases involve two visits. Temporary teeth can usually be provided in the meantime so you are not without them.
