A gum can look completely healed after a tooth is removed. Underneath, the bony ridge may already be thinner than it was before. That difference matters when an implant is planned: the new root needs bone in the right place, not merely somewhere inside the gap.
The alveolar ridge is the raised section of jawbone that once held the tooth roots. Tooth loss changes it. The cheek-side wall commonly becomes thinner first; height can reduce as well.
Sometimes there was little bone to begin with. In other cases, an old infection, difficult extraction or long-empty space has left a local defect.
Alveolar ridge augmentation rebuilds that tooth-bearing area. It is a focused procedure, usually connected with future implant treatment. Restoring the border or continuity of the jaw is a much larger reconstructive task and belongs on another service page.
This catches patients by surprise. The gum may appear broad enough while the bone beneath it is little more than a narrow plate.
A visual examination still matters, but it cannot provide the full measurement. CT shows the ridge in three dimensions and answers the useful questions: how much width remains, where is the defect, and what lies close to the intended implant position?
The future crown sets the target. The surgeon plans where the implant ought to sit for a natural shape and practical cleaning, then checks the bone around that position. If the implant has to be moved simply to chase the remaining bone, the final tooth may become awkward.
That is when a dental bone graft before implant enters the plan.
No one requests “more bone” in the abstract. The missing volume has an address.
A horizontal defect leaves the ridge too narrow. A vertical one lacks height. Some sites have both problems, although vertical rebuilding tends to demand more control because the graft must keep its form above the existing bone.
An alveolar bone graft is designed around that exact deficit. Extra material placed outside the useful zone does not improve the implant plan. It may only make closure and later cleaning more difficult.
Bone and gum tissue do not rebuild at the same speed. Gum wins the race.
During guided bone regeneration, graft particles are placed where extra bone is required. A barrier is then positioned over them. Think of it as a temporary roof: it protects the space while bone develops underneath instead of letting faster-growing soft tissue move in first.
The guided bone regeneration membrane may be resorbable, meaning the body gradually breaks it down. A non-resorbable version stays longer and can require a later removal appointment. Defect shape and the amount of support needed guide that choice.
GBR is the name of the technique, not a particular commercial kit. The membrane, graft and fixation are selected separately.
A small outer-wall defect can sometimes be corrected when the implant is placed. The existing ridge holds the implant firmly; the graft restores the missing contour around it.
A larger deficit changes the order. Alveolar bone graft surgery is carried out first, followed by a healing period. The implant appointment comes later, once the ridge has been reassessed.
Patients naturally like the sound of one operation. Still, combining two stages only makes sense when the implant can gain dependable stability from the bone already present. Convenience cannot replace that requirement.
A block graft or controlled ridge-expansion method may suit certain narrow sites. The surgeon chooses by looking at the full shape, not one thickness measurement taken from the scan.
The graft can include the patient’s own bone, processed human donor material, an animal-derived material, a synthetic substitute or a mixture.
These materials do not all behave identically. The graft mainly creates a framework. The patient’s bone then grows into that framework and changes it over time.
Origin should never be a last-minute surprise. Anyone who wishes to avoid an animal-derived product should raise the point during planning. That leaves time to discuss whether a suitable alternative exists for this particular defect.
The area is usually numbed with local anaesthetic. The gum is moved aside carefully, the recipient site is prepared and the planned volume is built.
Now comes a less obvious issue: nothing should wobble. Graft particles and the membrane may be secured with small pins, screws or another fixation method. The gum is then brought back over the site.
A relaxed closure is the aim. If the tissue has to be stretched tightly, the edges are more likely to separate during early healing. For that reason, the surgeon studies the gum as closely as the missing bone.
Some swelling and tenderness are expected early on. Swelling may feel more pronounced around the second day before beginning to settle. A donor area, when the patient’s own bone has been collected, brings its own short recovery.
Leave the site alone. Repeated checks with a tongue or finger add nothing useful. Cleaning, mouthwash and food advice will reflect the exact method used.
A temporary removable tooth can also matter. If it presses against the graft, it may need adjustment before being worn again. Bring it to the clinic instead of deciding by feel.
Smoking makes the local blood supply less reliable and raises the risk of graft complications. This is one of those occasions when “cutting down” and stopping are not quite the same promise to the tissues.
Contact UKRMED if swelling settles and then returns, a persistent unpleasant taste develops, discharge appears or part of the membrane can be seen.
A dental bone graft cost depends on how much volume is missing and what is needed to rebuild it. Graft source, membrane, fixation and simultaneous implant placement can all change the estimate.
A maxillofacial surgeon consultation at UKRMED costs UAH 1,000. CT of one jaw with a report costs UAH 930 when included in the diagnostic plan. The grafting fee is confirmed after the scan has been reviewed.
The procedure may also be listed as guided bone regeneration Kyiv or alveolar ridge augmentation UKRMED.
No. Ridge augmentation repairs a local tooth-bearing site, generally for a planned implant. Full jaw reconstruction may involve the outer border, contour or continuity of the jaw. Same word — bone — but a very different scale.
Not definitely. A membrane belongs to the GBR approach. A block graft or another ridge technique can use a different method of stabilisation. The shape of the defect decides more than the name of the procedure.
Possibly. The remaining bone must grip the implant securely before any graft is added. If it cannot do that, the sensible order is graft first, implant later.
Time gives only a rough guide. Graft type, size and the patient’s healing all change the pace. The surgeon checks the site clinically and uses new imaging when it will help decide the next step.
Occasionally. A different implant size, angle or prosthetic solution may work. But moving an implant into a poor position simply to avoid grafting can create a crown that looks wrong, cleans badly or carries load poorly.
Book a review instead of testing or covering it at home. A small exposed area and a larger opening are managed differently, and the membrane type matters too. The surgeon needs to see the tissue before deciding what comes next.
