Bone Grafting & Sinus Lift for Full-Arch Implants: Do You Need One?
Specialist Prosthodontist · Taki Dent, Antalya
Bone grafting rebuilds missing jawbone and a sinus lift creates room for upper-jaw implants. A key advantage of All-on-4 is that it is specifically designed to avoid these procedures — by angling the rear implants forward, it engages the bone you still have and sidesteps the sinus, so most patients need no graft at all. All-on-6, with more upright posterior implants, occasionally needs minor grafting or a small sinus lift in the upper jaw. When grafting is genuinely required it adds time and cost. Taki Dent plans implant angles on a CT scan to minimise grafting wherever possible.
What are bone grafting and a sinus lift?
When teeth are lost, the jawbone that held them shrinks over time. Bone grafting adds material to rebuild that lost volume so an implant has something solid to anchor into. A sinus lift is a specific upper-jaw graft: the floor of the sinus is gently raised and bone added beneath it, creating height for implants in the back of the upper jaw where bone is often thin.
These are routine, safe procedures — but they add months of healing and cost, so avoiding them when possible is a real benefit.
| All-on-4 | All-on-6 | |
|---|---|---|
| Grafting needed | Rarely | Sometimes (upper jaw) |
| Sinus lift needed | Usually avoided | Occasionally |
| Why | Angled rear implants | More upright implants |
| Effect on timeline | Faster | May add healing time |
Why does All-on-4 often avoid grafting?
This is the clever part of the protocol. Instead of placing rear implants straight down into the thin, sinus-adjacent bone that would need a lift, All-on-4 tilts them forward at an angle. That angle does two things: it lets the implant engage the denser bone further forward, and it routes around the sinus entirely.
The result is that most patients who were told they "did not have enough bone for implants" can in fact have All-on-4 with no graft. It is one of the reasons the technique transformed full-arch treatment.
When is grafting still needed?
Grafting becomes likely when bone loss is severe and even angled implants cannot find enough anchorage, or when a patient specifically wants the more upright six-implant All-on-6 layout in a resorbed upper jaw. In those cases a minor graft or small sinus lift may be planned. The only way to know is a CT scan — it shows the exact bone volume and lets the surgeon design implant angles that minimise or eliminate grafting.

Frequently asked questions
I was told I have no bone for implants — can I still get All-on-4?
Very often, yes. All-on-4 angles the rear implants to use the bone you still have and avoid the sinus, so many patients refused implants elsewhere are suitable. A CT scan confirms it.
Does a sinus lift hurt?
It is done under local anaesthetic, often with sedation, and most patients report mild discomfort and swelling for a few days, controlled with standard painkillers.
Does grafting add a lot to the cost?
It adds some cost and healing time, which is one reason the graft-avoiding All-on-4 design is attractive. Taki Dent plans angles to minimise grafting and quotes any graft transparently up front.
