Block bone graft in Turkey: what it is and what it is for
A block bone graft is a dental surgical procedure in which a solid piece of bone is fixed onto a jaw that is too thin or too short to hold a dental implant. The block is shaped to fit the defect and held in place with small titanium screws. Over the following months your own bone grows into the graft and gradually replaces it, leaving a ridge wide and tall enough for an implant. Dental departments and oral surgery clinics in Turkey use block grafts mainly for large or complex defects, and often as the first stage of a full implant treatment.
It is not a cosmetic procedure and not a treatment in itself: it prepares the jaw. This guide explains how a block bone graft works, where the bone comes from, what it costs compared with the UK, US and Germany, how long healing takes and how to choose a clinic. For the wider picture see our dental treatments in Turkey.
Why do some people need a block bone graft?
Jaw bone shrinks when a tooth is lost. The outer wall of the socket is thin and is absorbed first, so after months or years the ridge becomes narrow, or lower in height, or both. Other causes are gum disease, an injury, a cyst or tumour removed from the jaw, an old infection, and teeth that have been missing since childhood. An implant needs a certain amount of bone around it for stability; a dentist measures this on a 3D cone-beam CT scan and may recommend a graft when the ridge is too narrow or too low.
A block is chosen when the defect is large or when the bone has to be rebuilt in a defined shape: a missing front tooth with a collapsed ridge, a wide gap where several teeth were lost, or a vertical deficiency.
Where does the bone for a block graft come from?
There are four common sources, and the surgeon chooses according to the size and site of the defect.
- Your own bone from the chin (symphysis). A small block from the front of the lower jaw suits defects of one to three teeth. It heals well but can leave temporary numbness of the lower teeth or chin skin.
- Your own bone from the back of the lower jaw (ramus). The block is taken from the area near the wisdom teeth; if a wisdom tooth is removed at the same time, see wisdom tooth removal. It is a common choice for larger defects and has a lower risk of chin numbness.
- Your own bone from the hip (iliac crest). Used for very large defects and needs a second surgical site and often general anaesthesia and a hospital stay.
- Donor bone (allograft) or animal-derived bone (xenograft). Processed, sterilised bone blocks avoid a second wound in the mouth. They are slower to be replaced by your own bone, and some patients prefer your own bone for that reason.
Your own bone contains living cells that help form new bone, but the choice is a surgical decision: ask why a particular source is proposed for you.
How is a block bone graft done step by step?
The operation is usually done under local anaesthesia, with sedation if you are anxious, and takes between one and two and a half hours depending on the donor site. The surgeon opens the gum over the defect, prepares the receiving area and, if your own bone is used, harvests the block through a second incision in the mouth. The block is shaped, fixed with screws, and any gaps are filled with bone granules. A thin collagen membrane is often placed over the graft to protect it, and the gum is closed without tension with stitches. The screws are taken out later, usually when the implants are placed.
Because the graft must be completely covered by gum while it heals, gum closure is the most technically demanding part. A graft that is exposed early may become infected or be absorbed.
Block bone graft or particulate graft for a thin ridge?
Both rebuild bone; they differ in how much they can rebuild and how predictable the shape is. A particulate graft uses granules of bone held in place by a membrane (guided bone regeneration). It is less invasive, usually needs no second wound and is widely used. A block provides a rigid shape and can rebuild more volume, especially width, but the harvesting adds a surgical site. A third option, sinus lifting, is a different procedure for the upper back jaw; see sinus lifting.
| Method | Best suited to | Typical limits |
|---|---|---|
| Block bone graft | Large width or height defects, several missing teeth | Second surgical site if own bone is used; longer healing |
| Particulate graft with membrane | Small and medium defects, around implants | Less volume, less rigid shape |
| Sinus lift | Upper back jaw lacking height | Only for the sinus area |
| Short or narrow implants | Moderate bone loss in some sites | Not suitable for severe loss |
When large jaw discrepancies are the cause, the problem may need a different treatment altogether, such as orthognathic surgery. The surgeon should explain why a block is recommended over simpler options.
Does a block bone graft work? What the evidence says
Yes, in appropriate cases. Reviews of dental research show that block grafts from your own jaw rebuild enough bone for implants in most patients, and implants placed in grafted bone can survive well over time. Evidence also shows that some of the graft is absorbed during healing, so surgeons often build the ridge slightly larger than needed. The graft is less predictable when the gum is thin, in smokers, in people with poorly controlled diabetes and in very large vertical defects. No clinic can guarantee a particular outcome; a trustworthy one will explain the failure risk and what happens if the graft does not integrate.
Block bone graft cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for one graft site, not hospital quotes. They exclude the implants and crowns. Each hospital confirms its own price in a written quote.
| Country | Approximate cost range per site |
|---|---|
| Turkey | €400 – €1,500 |
| United Kingdom | €1,200 – €3,500 |
| United States | €1,500 – €4,500 |
| Germany | €900 – €3,000 |
What changes the price: the donor source (a hip graft costs far more than a chin graft), the size of the defect, the material and membrane, the type of anaesthesia, and the pre-operative CT scan. A block bone graft price should be read alongside the whole plan, because the graft is only the first step: implants and crowns are charged separately. Ask the clinic to list what is included, such as the scan, medication, follow-up and screw removal.
Who is a good candidate for a block bone graft, and who is not?
Good candidates are adults in reasonable general health who want an implant and whose scan shows insufficient bone. You need healthy gums, good oral hygiene and a willingness to wait for healing. A graft is riskier if you smoke heavily and cannot stop, have uncontrolled diabetes, take bisphosphonate or similar bone medicines, have had radiotherapy to the jaw, or have active gum disease or infection. The surgeon may ask for a medical report and will treat any infection first.
Block bone graft recovery: swelling, healing and how long to wait for implants
Expect swelling, bruising and soreness for several days, worst on the second and third days. Cold compresses, prescribed painkillers and antibiotics help. A soft diet is needed for one to two weeks, and you should not brush the graft site until the surgeon allows it. Stitches come out after about ten to fourteen days. Bone needs time to unite with the graft: implants are usually placed after four to six months for your own bone and sometimes longer for donor or animal bone. Chin donor sites can feel numb or tingly for weeks or months.
For travellers this usually means two trips: one for the graft, a few days to a week long, and a second months later for the implants, with screw removal at that point. Our page on how it works explains how the stages are coordinated.
Risks and complications of a block bone graft
Common effects are swelling, bruising, pain and a tight feeling in the gum. Less common problems include infection, exposure of the graft through the gum, partial loss of the graft, numbness or altered sensation in the lip, chin or teeth from nerve irritation, bleeding, and damage to neighbouring teeth at the donor site. For hip grafts there can be pain when walking for some days or weeks. Rarely, the graft fails completely and must be removed, and the procedure repeated later. The NHS and professional bodies such as the British Society of Periodontology and Implant Dentistry advise discussing these risks, and stopping smoking, before surgery. Ask what the clinic does if a problem appears after you have flown home.
How to choose a surgeon and clinic, and what to ask
Check that the surgeon is a dentist or maxillofacial surgeon trained in bone grafting and implant surgery, that the clinic has its own 3D CT scanner and a sterile surgical room, and that you receive a written treatment plan with a price and timetable before paying a deposit. Red flags include a firm price without a scan, promises that the graft will "always take", pressure to book quickly, no named surgeon and no plan for complications. Request a plan through our free quote page and send your scan; the hospital reviews it and replies with a written plan.
Questions to ask the clinic:
- Which donor source do you propose and why?
- How much bone is missing on my scan, and how much will be rebuilt?
- How long do I wait before implants, and how many trips are needed?
- What happens if the graft is lost or exposed?
- Who looks after me after I return home?

Frequently asked questions
A block bone graft is a dental procedure that fixes a solid piece of bone onto a thin or short part of the jaw. Over several months your own bone replaces it, leaving a ridge strong enough to hold a dental implant.
Usually your own chin or the back of your lower jaw. For very large defects the hip may be used, and some clinics use sterilised donor or animal-derived bone blocks instead, which avoids a second wound.
Approximate ranges are €400 to €1,500 per site in Turkey, against about €1,200 to €3,500 in the UK. Implants and crowns are charged separately, and the hospital confirms its price in a written quote.
In suitable patients it rebuilds enough bone for implants in most cases, though some of the graft is absorbed during healing. Smoking, thin gums and poorly controlled diabetes lower the chance of success.
The area is numbed during surgery. Afterwards soreness and swelling are common for several days and are usually controlled with prescribed painkillers. A donor site in the chin can feel numb or tingly for a while.
Implants are usually placed after four to six months for your own bone, and sometimes longer for donor or animal bone. Your surgeon confirms timing with a follow-up scan.
Granules with a membrane are less invasive and suit small or medium defects. A block gives a rigid shape and more volume, but may need a second surgical site. The surgeon decides from your scan.
The commonest problems are swelling and bruising. Less often the gum opens and exposes the graft, infection develops, part of the graft is lost or a nerve is irritated, causing numbness in the lip or chin.
The graft stage usually needs about four to seven days, including a check and stitch plan. Implants are placed on a second visit some months later, so plan for two trips.
Yes, a 3D cone-beam CT scan is the standard way to measure how much bone is missing and to plan the graft. A reliable clinic will not give a firm plan or price without one.
