Bone Grafts & Sinus Lifts Explained

You sent your X-rays to a Turkish clinic expecting a straightforward implant quote. Instead, the treatment plan includes "bone graft" and "sinus lift" — procedures you've never heard of, adding £400-1,000 to the bill.

Don't panic. These are routine procedures. Around 50% of implant patients need some form of bone augmentation. The clinic isn't upselling you — they're being thorough.

Why You Might Need Bone Work

Dental implants need bone to anchor into. A standard implant is 8-13mm long and 3.5-5mm wide. If your jawbone is thinner or shallower than this, the implant won't have enough support.

Common reasons for insufficient bone:

If you've been missing teeth for more than a year, there's a good chance bone has resorbed. The longer the gap, the more bone loss.

Bone Grafts Explained

A bone graft adds volume to your jawbone so it can support an implant.

Types of Bone Graft

Most Turkish clinics use xenograft (bovine bone) — it's the global standard for dental bone grafting. The material is completely sterilised and processed; it serves as a scaffold for your body to grow new bone into.

The Procedure

1. Local anaesthesia (or IV sedation for anxious patients)
2. Small incision in the gum to expose the bone
3. Bone graft material packed into the deficient area
4. A collagen membrane placed over the graft to protect it
5. Gum stitched closed
6. Healing: 4-6 months before the implant can be placed

Duration: 30-60 minutes per site Pain level: Mild to moderate soreness for 3-5 days. Less painful than extraction.

Sinus Lifts Explained

A sinus lift is specific to the upper back jaw. Your maxillary sinuses — the air-filled cavities behind your cheekbones — sit directly above your upper molars. When upper back teeth are lost, the sinus floor drops and bone thins, leaving too little bone for implants.

A sinus lift raises the sinus membrane and packs bone graft material underneath it, creating enough depth for implant placement.

Types of Sinus Lift

Internal sinus lift is simpler: the surgeon drills the implant hole, gently pushes the sinus membrane up, and packs a small amount of bone graft. The implant is often placed at the same time.

External sinus lift is needed when bone is very thin (less than 5mm). A small window is cut in the side of the upper jaw, the membrane is lifted, and a larger volume of graft material is placed. Implants are placed 6-9 months later after the graft has matured.

The Procedure

1. Local anaesthesia or IV sedation
2. For external: incision in gum, small window created in bone with piezoelectric surgery (ultrasonic — precise, no damage to membrane)
3. Sinus membrane gently lifted
4. Bone graft material packed into the space
5. For external: window covered with membrane, gum stitched closed
6. For internal: implant placed immediately through the same access hole

Duration: 45-90 minutes per side Pain level: Moderate soreness for 5-7 days. More swelling than a bone graft because of the sinus involvement.

How This Affects Your Travel Plans

The big question: does bone work mean two trips?

If your clinic says one trip: They're likely doing an internal sinus lift or a small graft with simultaneous implant placement. This is standard practice when existing bone provides enough initial stability.

If your clinic says two trips: They're being conservative — the graft or sinus lift needs to heal before loading it with an implant. This is the safer approach for complex cases. Budget an extra £300-600 for the second trip (flights + 3-4 nights hotel).

Do You Actually Need It?

Some patients question whether bone work is necessary. Here's how to verify:

Get a CBCT scan. A panoramic X-ray (OPG) gives a 2D view. A CBCT scan shows bone in 3D with exact measurements. The CBCT tells the surgeon precisely how much bone exists at each implant site.

Get a second opinion. Send your CBCT to 2-3 clinics. If all agree you need a bone graft, you need one. If one says you don't, ask why — they may be planning a shorter implant, a different angle, or a zygomatic implant that bypasses the bone entirely.

Ask about alternatives:

• Short implants (6-8mm) — may work without grafting in moderately thin bone
• Tilted implants — angled to engage existing bone (used in All-on-4 protocol)
• Zygomatic implants — anchor into the cheekbone, bypassing the upper jaw entirely (complex, specialist procedure)

Post-Procedure Care

After bone grafts or sinus lifts:

• Don't blow your nose for 2-3 weeks (sinus lift) — pressure can dislodge the graft
• Sneeze with your mouth open — same reason
• Don't fly for 7-14 days after a sinus lift (cabin pressure affects the sinus cavity)
• No strenuous exercise for 1-2 weeks
• Sleep with head elevated for the first week
• Soft food for 1-2 weeks
• Take antibiotics exactly as prescribed — graft infection is the main risk

Getting an Assessment

Not sure if you need bone work? Our dental assessment helps identify what's needed. Upload your X-rays and clinics can assess bone levels before you fly — no surprises on arrival.
