Do I need a bone graft or sinus lift for dental implants?
Specialist Prosthodontist · Taki Dent, Antalya
Quick answer
Whether you need a bone graft or sinus lift depends on the quality and volume of your jawbone. After tooth loss, bone resorbs, often leaving insufficient depth or width for an implant. A sinus lift is required when the maxillary sinuses are too close to the implant site. These procedures are routine and add 3–6 months healing. Costs in Turkey: bone graft £300–£600, sinus lift £600–£1,200, often included in package prices.
Bone grafting and sinus lifts are common, predictable procedures that create a solid foundation for dental implants. If you've been told you lack enough bone, don't worry — these techniques have been refined over decades and are performed routinely in modern implant dentistry.
Why is bone lost after tooth extraction?
When a tooth is removed, the bundle of nerves and blood vessels that once nourished it is also lost. The surrounding jawbone no longer receives the stimulation that chewing provided, so it begins to resorb (shrink). In the first year after extraction, up to 25% of bone width can be lost. Over time, this can leave insufficient bone volume to securely hold an implant.
This resorption is especially pronounced in the upper jaw, where the maxillary sinuses can expand into the space left by missing teeth. That's why a sinus lift is often needed for upper back teeth.
When exactly do you need a bone graft?
Your implant dentist will assess bone volume using a 3D CT scan. You typically need a graft if:
- The jawbone is too narrow (< 5 mm wide) to encase the implant.
- The bone height is insufficient (especially in the upper jaw near the sinus).
- There is a defect from previous infection, trauma, or cyst removal.
- You have been without teeth for many years, leading to advanced resorption.
Even mild deficiency can be managed with a small graft at the time of implant placement, adding little extra time.
What is a sinus lift and when is it needed?
A sinus lift (or sinus augmentation) is a procedure that elevates the sinus membrane and places bone graft material in the floor of the maxillary sinus. This creates enough bone height to place implants in the upper premolar and molar region. It is required when the sinus is too close to the ridge — often the case after upper tooth loss.
The procedure is performed under local anaesthesia or sedation. There are two approaches:
- Lateral window technique: a small window is cut in the bone of the sinus wall, the membrane is lifted, and graft is placed.
- Transcrestal (osteotome) technique: a less invasive approach used when minimal height is needed (e.g., 2–4 mm).
Both are well-tolerated and have high success rates.
What types of bone graft are used?
Several graft materials are available, each with pros and cons:
| Type | Source | Key features |
|---|---|---|
| Autograft | Your own bone (chin, hip, tibia) | Gold standard for healing, but requires second surgical site. |
| Allograft | Donor bone (processed, sterile) | No second site; good osteoconductivity; very safe. |
| Xenograft | Bovine or porcine bone | Slowly resorbs, provides scaffold; very common. |
| Alloplast | Synthetic (TCP, HA, bioactive glass) | No biological risks; predictable; often used alone or mixed. |
At Taki Dent, we typically use a combination of xenograft and alloplast for predictable, long-lasting results. Your surgeon will choose the best option for your case.
How much extra healing time is needed?
Healing time depends on the size of the graft and the technique used:
- Minor graft placed with implant: no extra waiting — the implant heals as the graft integrates.
- Moderate graft (1–2 tooth site): 3–4 months before implant placement.
- Large graft or sinus lift: 4–6 months for the graft to mature before implant placement.
- After implant placement: additional 3–4 months for osseointegration before fitting the crown.
While this extends overall treatment time, the result is a stable, long-lasting implant that feels and functions like a natural tooth.
What are the costs in Turkey compared to the UK?
Bone grafting and sinus lifts are often included in the implant package price at Turkish clinics. As a guide:
- Bone graft (per site): £300–£600 in Turkey; £600–£1,500 in the UK.
- Sinus lift (per side): £600–£1,200 in Turkey; £1,500–£3,000 in the UK.
- Single implant with crown: £750–£1,400 in Turkey; £2,000–£2,500 in the UK.
- All-on-4 per arch: £4,500–£7,500 in Turkey; £10,000–£15,000 in the UK.
These savings (often 50–70%) reflect lower overheads, not lower quality. Many Turkish clinics, including Dr. Sadık Taki's practice, use premium implant systems (Straumann, Nobel Biocare) and advanced technology.
Is the procedure painful or risky?
Both bone grafting and sinus lifts are performed under effective local anaesthesia, so you won't feel pain during the procedure. Post-operative discomfort is usually mild and managed with over-the-counter painkillers. Swelling and bruising may occur but subside within a week. Complications such as infection or graft failure are rare (around 1–3%) and less common when performed by an experienced specialist.
How can I know if I need these procedures?
The only way to know is through a clinical examination and 3D imaging. Many patients are surprised to learn they have adequate bone without grafting. Conversely, some with seemingly good bone may need a small graft for long-term stability.

Frequently asked questions
Does a bone graft hurt?
The procedure is performed under local anaesthetic, so you won't feel pain. Afterward, mild discomfort is normal and easily managed with over-the-counter pain relief. Most patients report less pain than a tooth extraction.
Can I have a sinus lift and implants at the same time?
Yes, if the bone height is sufficient for initial implant stability. When minimal lift is needed, the implant can be placed simultaneously. For larger lifts, a separate 4–6 month healing period is required before implant placement.
How long does a bone graft last?
Bone graft material is gradually replaced by your own living bone over 6–12 months. Once integrated, it becomes part of your jaw and lasts a lifetime, provided you maintain good oral hygiene and regular dental check-ups.
Are there alternatives to bone grafting?
In some cases, shorter implants (6–8 mm) or tilted implants (All-on-4 technique) can avoid the need for grafting. However, if bone volume is severely lacking, grafting is the most predictable solution for long-term success.
What is the success rate of sinus lifts?
Sinus lift procedures have a success rate of over 95% when performed by an experienced specialist. The subsequent implants also have high survival rates, similar to implants placed in natural bone.
Can I fly after a sinus lift?
It's advisable to wait at least 2–3 weeks before flying, as pressure changes can affect the sinus. Your dentist will give you specific advice based on the extent of your procedure.
