Why you might not have enough bone for implants
An implant needs enough healthy bone around it, in height and width, to hold firmly while it heals and for years afterwards. Jawbone that no longer has a tooth to support gradually shrinks. That’s why bone is often thin after:
- Teeth that were taken out years ago, especially if the gap was never filled
- Long-term denture wearing, which slowly wears the ridge down
- Gum disease (periodontitis), infections or injury
- In the back of the upper jaw, the sinus enlarging downwards into space where roots used to be
A bone graft rebuilds the missing bone. A sinus lift is a specific kind of graft for the back of the upper jaw.
Types of dental bone graft
Socket preservation
- Graft placed straight after an extraction
- Limits the shrinkage that follows
- The smallest and quickest to heal
Ridge augmentation
- Builds up a narrow or low jaw ridge
- Granules under a membrane, or a block of bone
- Sometimes done at the same time as the implant
Sinus lift
- Adds bone under the sinus floor
- Back of the upper jaw only
- Internal or lateral technique (see below)
Larger reconstruction
- For severe bone loss
- May use bone from elsewhere in the body
- Often done in hospital, with longer healing
The graft material can be your own bone, donated human bone, animal-derived bone (most often bovine) or a synthetic substitute, usually covered by a membrane. Your own bone is often described as the gold standard, but taking it means a second surgical site. Cochrane reviews have not found that any one material or technique clearly leads to fewer implant failures than the others.
What a sinus lift is: internal vs lateral
The maxillary sinuses sit just above the roots of the upper back teeth. A sinus lift gently raises the thin lining of the sinus floor and places graft material underneath, creating height for an implant.
Internal (crestal) lift
- Done through the hole prepared for the implant
- Needs some existing bone; gains a few millimetres
- Implant usually placed in the same operation
- Smaller procedure, fewer reported complications
Lateral (external) lift
- A small window is made in the side of the jaw
- Used when more height is needed
- Implant placed at the same time or months later
- More swelling and a longer recovery
When do you need a bone graft or sinus lift?
Only a 3D cone beam CT (CBCT) scan can show how much bone you have, where it is, and how close the sinus and nerves are. A panoramic X-ray or a photo isn’t enough to decide. If you’ve had a CT scan in the UK, ask for a copy to send with your quote request.
Be cautious if grafting appears on every plan, or on none
Alternatives to bone grafting
- Short implants. A Cochrane review compared short implants (5–8.5 mm) with sinus lifts where there was 4–9 mm of bone. It found too little evidence to say either had fewer failures after a year, but more complications at sites treated with a sinus lift.
- Angled implants. Full-arch techniques like All-on-4 tilt the back implants to use the bone that’s left, which can avoid grafting.
- Zygomatic or pterygoid implants. For severe upper-jaw bone loss, long implants anchored in the cheekbone can replace grafting. See zygomatic implants in Turkey.
- Fewer implants, or a different restoration. A bridge, an implant-retained denture or a conventional denture may suit some people better.
Not every alternative suits every mouth. A good surgeon will explain why they’re recommending a graft over these options, using your scan.
Healing times and how many trips to Turkey
Grafted bone needs time to mature before it can hold an implant. Published guidance gives a range: around 3–9 months for most grafts, and an NHS trust leaflet puts bone healing after a lateral sinus lift at about 4–9 months, with 6–12 months or longer from surgery to final teeth.
Trip 1
About 7–10 days
CT scan, then the graft or sinus lift. Stay long enough for a review and stitch check.
Trip 2
About 5–7 days
Around 4–9 months later, once a scan shows the bone is ready: implant surgery.
Trip 3
About 5–7 days
Around 3–6 months after that: final crowns or bridge fitted.
That’s a staged plan. If the graft can be done at the same time as the implants, which is common with smaller grafts and internal sinus lifts, it’s usually two trips, with a longer gap before the final teeth. More in our implant timeline guide.
Bone graft and sinus lift cost: UK vs Turkey
Typical published ranges, October 2026. Turkish grafting prices are less consistent than implant prices, and many “from” implant prices exclude grafting entirely. Your quote from us will be in GBP and will list the graft, the material and the membrane separately.

The risks, honestly
Grafting is routine for implant surgeons, but it’s still surgery. One NHS trust gives these figures for sinus lifts in its patient information:
- A tear in the sinus lining during surgery: about 19% with the lateral technique and 3.8% with the internal one. It’s often repaired at the time, or the lift is paused and retried after healing.
- Infection: about 2.9% (lateral) and 0.8% (internal).
- Graft exposure through the gum (about 3%), or the graft failing to form bone (about 1.9% with the lateral technique), with a higher risk in smokers.
- Swelling, bruising and a blocked-sinus feeling for days to weeks; nosebleeds are common early on.
- Numbness of the cheek, gum or teeth, usually temporary and very rarely permanent.
When things go wrong after a sinus lift, they can be hard to fix, especially from another country. It’s why surgeon experience, a proper scan and enough healing time matter more here than price.
Smoking matters
Questions to ask any clinic
- Who will do the graft, and how many sinus lifts and grafts do they do a year?
- What does my CT scan show, and why is a graft needed rather than short or angled implants?
- Which technique, and will the implant go in at the same time?
- Which graft and membrane material, and is any of it animal-derived?
- How will you confirm the bone is ready before placing implants?
- How long should I wait before flying home?
- If the graft fails, who pays for the repeat surgery, flights and hotel?

Aftercare in the UK
Most of the healing happens at home, in the months between trips. Before you leave Turkey, make sure you have your CT scans, the operation notes, the graft and membrane products used, and a written aftercare plan.
- Follow the instructions you're given: usually no nose blowing for about two weeks after a sinus lift
- Take any prescribed antibiotics or decongestants as directed
- Get help if swelling or pain gets worse after the first couple of days, bleeding won't stop, you have a fever, or graft granules come out of your nose
- Tell your UK dentist what's been done, and book a check during the healing months
