Jaw Bone Grafting in Ukraine

Jawbone needs load to survive. While a tooth is in place, chewing forces pass through the root into the alveolar bone and maintain its volume; once the tooth is extracted, that load disappears and the bone starts to shrink. Most of the loss happens in the first months: within a year the ridge loses between a quarter and a half of its original width, after which the process slows down but does not stop.

An implant needs a certain amount of bone. At least 1 mm of natural bone must surround it on each side, with a safe distance from its tip to the mandibular canal and the floor of the maxillary sinus. In practice, a standard-diameter implant needs a ridge about 6 mm wide or more; when bone loss leaves only 3–4 mm, there is no room for an implant, and that is when grafting is needed.

Indications include teeth that have been missing for a long time, a traumatic extraction that fractured the socket wall, the after-effects of cysts, granulomas and chronic periodontitis, bone loss from gum disease, jaw injuries and congenital defects. The back of the upper jaw is a special case: the sinus expands downwards over time, leaving 2–5 mm of bone height, and a sinus lift is used there (it has its own page in our catalogue).

The procedure is not suitable for everyone. Planned grafting is postponed or ruled out in the case of untreated gum disease and poor hygiene, uncontrolled diabetes, acute inflammation in the mouth, pregnancy, during chemotherapy, after radiotherapy to the head and neck, and in patients receiving intravenous bisphosphonates or denosumab injections, in whom medication-related osteonecrosis of the jaw is possible. Heavy smoking does not formally rule out the procedure, but it noticeably worsens the outlook, and the surgeon will discuss this with you beforehand.

MediUkraine is a treatment search and coordination service, not a clinic. We choose the clinic and a surgeon with the right specialism, arrange the dates and support you throughout, including if you are travelling from abroad. The scope of the procedure, the technique and the material are decided by the doctor after an in-person examination and a review of the CT scan.

Guided bone regeneration is the core technique: bone material is placed in the deficient area and covered with a barrier membrane. The membrane is there not for strength but to keep tissues apart. Gum epithelium and connective tissue grow several times faster than bone and, without a barrier, would simply fill the space meant for new bone; under the membrane, the clot matures into bone undisturbed over months. That is why an intact membrane and watertight stitches matter as much as the material itself.

Autogenous bone, your own bone, is the only material containing living bone-forming cells. It is taken near the surgical site: from the external oblique ridge or ramus of the lower jaw, the retromolar area or, less often, the chin; small amounts are collected with a bone scraper or a filter trap during drilling. Autogenous bone matures fastest but has two limitations: only a small volume is available, and it resorbs noticeably, so it is usually mixed roughly half and half with a slow-resorbing material rather than used alone.

Xenogeneic granules are bovine or porcine bone with all proteins removed, leaving a naturally porous mineral framework. This material barely resorbs and maintains the gained volume for years, so it is used when the ridge shape needs to be preserved long term. Allogeneic materials are processed human donor bone from a tissue bank. Alloplasts based on beta-tricalcium phosphate and hydroxyapatite are fully synthetic: the body replaces them with its own tissue, but they also lose volume faster.

Membranes are divided into resorbable and non-resorbable. A resorbable collagen membrane dissolves over several weeks or months and does not need removing; it is used for small and medium defects. Non-resorbable PTFE membranes, often titanium-reinforced, and titanium meshes hold their shape even under pressure from the soft tissues, so they are essential for large reconstructions; they are fixed with pins or microscrews and removed in a separate procedure several months later. The trade-off for rigidity is a higher risk of the membrane edge becoming exposed through the stitches.

Alveolar ridge splitting is used when bone height is sufficient but the ridge is narrow, about 3–5 mm. The ridge is cut lengthwise with a piezo scalpel or thin discs, the outer and inner walls are gently spread apart, and the gap between them is filled with graft material. The method gains width immediately, often allows an implant to be placed at the same time and shortens treatment by months. It needs a layer of spongy bone between the cortical plates, so it is not always possible on a thin, knife-edge lower ridge.

When the defect is large, a bone block is used: a piece of your own bone from the ramus of the lower jaw, or an allogeneic block, is fitted against the ridge and fixed with microscrews, and the gaps are filled with granules and covered with a membrane. A block gives predictable width but is more invasive because of the second surgical site. The most challenging area is vertical augmentation, when the ridge lacks height: titanium mesh, tenting screws and sometimes distraction osteogenesis are used, and surgeons openly acknowledge that vertical gain is less predictable than horizontal gain and more often comes with membrane exposure.

Socket preservation is worth knowing about separately. If bone material is placed in the socket straight after an extraction and covered with a membrane, the ridge loses much less volume than with normal healing. It is a short procedure done at the same visit, and it often avoids the need for full grafting a year later. If you are having a tooth out and plan an implant later, ask about this option before the extraction.

The key planning decision is whether to graft separately or at the same time as placing the implant. If the deficit is small and the implant can go in the correct position with enough primary stability, both are done in one visit. If there is so little bone that the implant will not hold or will sit at the wrong angle, the stages are separated: bone first, then the implant once the graft has matured. Trying to save a visit in this situation usually ends in losing the implant.

Healing times depend on the size and type of the defect. Small horizontal defects and sockets are ready after about 4 months, large horizontal ones after 6, and vertical reconstructions and blocks after 6–9 months. Readiness is judged not by the calendar but by a follow-up CT scan: the doctor checks whether density and width are sufficient for an implant of the required size. Platelet-rich fibrin and membranes made from your own blood help the soft tissues heal, but on their own they do not add volume.

There is no one-size-fits-all method, and it is worth knowing this before you pay. The choice between ridge splitting, granules under a membrane and a block depends on the shape of the defect, gum thickness, the condition of the neighbouring teeth, your habits and the planned restoration; the same millimetre deficit is treated differently in the upper and lower jaw. Only a doctor, after an examination and a review of the CT scan, can predict the outcome in your case, not remotely from a description or a smile photo.

Expect swelling for the first two to three days. It builds for 48–72 hours, then subsides, and by day 5–7 the face usually looks normal again; a bruise on the cheek or under the jaw may appear and fades on its own. Apply cold only on the first day, 15 minutes at a time with breaks; after that it no longer helps.

Take painkillers on the schedule the surgeon gives you, and finish the full course of any antibiotic prescribed. Do not rinse until the next day, so as not to dislodge the clot; after that you will be prescribed gentle chlorhexidine mouth baths, and the stitched area is cleaned carefully with a soft brush so that no plaque builds up. Avoid saunas, hot baths, the gym and straining or bending over for the first week.

After surgery on the upper jaw, do not blow your nose hard, puff out your cheeks, dive or play wind instruments for about two weeks: a change in pressure can shift the graft material. Sneeze with your mouth open. These restrictions are stricter if a sinus lift was done at the same time.

For the first two weeks, eat soft food that is not hot, and do not chew on the treated side. Stitches come out on day 7–14, sometimes later if a non-resorbable membrane was used. Do not wear a removable denture over the treated area until the doctor says so, or have it relined with a soft material so that it does not press on the stitches.

The result is judged not by how you feel but by a follow-up CT scan after 4–6 months, or 6–9 for large defects. There is one criterion: whether there is enough width, height and density to place an implant of the required diameter in the correct position. Some of the graft resorbs in this time; this is expected and allowed for, which is why the surgeon deliberately overbuilds the volume slightly.

To be honest about the method's limits: sometimes the gain is smaller than planned, and then either a smaller implant is placed or a smaller repeat graft is done. This happens mainly with vertical reconstructions and in smokers. It is a limitation of the technique, not necessarily the surgeon's mistake, which is why timelines and likely scenarios are discussed before surgery, not after the follow-up scan.
