Not Enough Bone

I was told I don't have enough bone: can I have implants?

Adding bone and waiting for months is not the only route

If a dentist has told you that your bone will not hold an implant, that sentence is not about your whole jaw; it is about the volume of bone a conventional implant looks for. On this page we explain the two layers of the jawbone and which of them resorbs after a tooth is taken out. Send us your images and we will write to you within one working day about where you stand.

Short answer

That sentence does not mean the door has closed. 'Not enough bone' means that the volume a conventional implant looks for is no longer there. Yet the hard outer layer of the jawbone (the cortical bone) is the part most resistant to resorption, and the strategic implant uses exactly that layer for its anchorage. This is why grafting and months of waiting do not come into it. If the outer layer is damaged as well, or if there is inflammation in your mouth that has not been brought under control, the method is not suitable. The decision is made by a 3D CBCT scan.

What decides it: A 3D CBCT scan

The two layers of the jawbone, and what happens when a tooth comes out

The jawbone is not a block of the same density throughout. On the outside there is a hard, dense layer that surrounds the whole jaw like an eggshell; this is called the cortical bone. On the inside there is a softer, porous tissue that looks like a sponge, which is where its name comes from: spongy bone. The roots of the teeth sit mainly in this inner tissue, while the hard outer layer is the load-bearing frame of the jaw.

When a tooth is taken out, the two layers do not behave in the same way. The job of the spongy bone was to surround the tooth root and take the force of chewing; once the tooth has gone, that area carries no load and it shrinks over time. This is largely what people mean when they talk about bone loss. The loss moves quickly in the first months, then slows down, but it does not stop. The hard outer layer, dense and tightly packed, is far more resistant to resorption; even years later it is largely still in place. In jaws where the loss is advanced, this layer thins as well.

A conventional implant sits on the side of this picture that resorbs. It is screwed into the bone, and then, for months, the spongy tissue around it is left to fuse with the implant surface. For that, a certain height and width of bone is needed around the implant. If the bone that is left falls short of that measurement, two routes remain: either volume is added with a graft and you wait for months, or the patient is told 'implants cannot be done for you'.

'You don't have enough bone' is the result of that measurement. It is not a wrong sentence, but an incomplete one. What it says is that the volume a conventional implant looks for is no longer there. What it does not say is whether your hard outer layer is still in place, because the conventional method does not target that layer and therefore has no reason to measure it either.

The strategic implant uses precisely this layer. Instead of looking for volume in the spongy bone, it is placed so that it reaches the hard outer layer, at an angle that locks into it mechanically. What provides the anchorage is not months of waiting for fusion, but this mechanical locking, which is there from the first day. That is why the final fixed teeth are fitted in three clinical days and why grafting does not come into it.

If the hard outer layer itself is damaged, or if there is inflammation in your mouth that has not been brought under control, the method is not suitable for you. That distinction is made by the examination and the 3D CBCT scan. Nobody can make the decision without looking at the images, and we do not either.

Who it can be done for, and who it cannot

The two lists below become clear after the CBCT scan. Seeing yourself in the second list does not mean the door has closed; some items do not mean 'no' but 'let's sort this out first'.

The tooth can be saved

Many missing teethThis protocol is for full-mouth cases and people missing many teeth. Dealing with the whole jaw in one plan is the most efficient way of using the bone you have left.
A jaw that has been without teeth for a long timeIf you have worn a denture for years, there is marked loss in the spongy bone. That does not mean the hard outer layer has gone as well; many of the cases the conventional method rules out come back onto the table here.
A graft has been recommended and you do not want onePlenty of patients put treatment off when faced with the idea of adding bone and waiting for months. We look at your images and tell you whether this step is needed in your case; and if it is, we say so just as plainly.
Diabetes that is being monitoredDiabetes is not a barrier. What matters is that your blood sugar is monitored and that there is no active inflammation in your mouth. We would like to see your medication and your most recent test results from the start.

Saving it is unlikely to hold

A single missing toothFor a single tooth, other solutions are more appropriate. The logic here is built on planning the whole jaw in one go; for one gap it is more extensive than it needs to be.
Gum inflammation that has not been brought under controlIf there is active inflammation in your mouth, we deal with that first. We do not place implants into inflamed ground. This item changes the order of things; it does not close the door.
Jaws where the hard outer layer is damaged tooA large cyst, previous jaw surgery or serious trauma can damage the cortical layer as well. Whether there is still a sound surface to anchor into is something the CBCT scan shows.
Uncontrolled general health conditions and certain medicationsA general health condition that is not under control, or certain medications that affect bone metabolism, will change the plan. We ask for the full list of the medicines you take at the first consultation; leaving this information out works against you.

How we reach the decision

This sequence is not the treatment; it is how the decision is made. At the end of it you know what is possible in your own jaw, and what that is based on.

1
Send us your images
If you have a panoramic X-ray or a CBCT scan, send it through the form. The images are read by the dentist who would carry out the treatment; the first reply is written by the dentist, not an assistant. You do not need to come in, and we get back to you within one working day.
2
The 3D CBCT scan
A panoramic X-ray is two-dimensional; it gives an idea of the height of the bone, but not of its thickness or the state of the hard outer layer. The decision in this method rests directly on where the cortical layer is, how thick it is and how sound it is, so we make no promises before we have seen a CBCT scan.
3
The rest of the mouth
Gum health, the state of the remaining teeth, roots that need taking out and the bite of the opposing jaw are all part of the plan. A plan built on bone measurements alone is an incomplete plan.
4
General health and medication
We would like to see your general health conditions, the medicines you take regularly and your most recent test results. Diabetes is not a barrier; it affects the planning and the order of things.
5
You get the plan in writing
How many implants, in which jaw, with what bridgework, and whether a graft is needed, are all shared in writing. If the method is not right for you, we write that just as plainly.
6
Three clinical days
If we agree on the plan, the surgery and the fitting of your final fixed teeth are spread over three clinical days. You know what will be done on which day before you come.

The routes on the table when you are told there is not enough bone

There is more than one route, and none of them is absolutely better than the others. Which one is right for you is decided by the picture in your own jaw.

A bone graft and waiting

The missing volume is made up with your own bone or with a bone substitute material, and it is left to heal before the implant; the wait is measured in months. If this is the right route, we say so; the price of it is an extra operation and a longer timeline.

A sinus lift

When the height of bone at the back of the upper jaw is reduced, the floor of the sinus cavity is pushed upwards to make room. It is often used in conventional implant planning; it means a separate operation and a separate healing period.

A strategic implant

Instead of looking for volume in the spongy bone, the implant is placed so that it locks into the hard outer layer. Grafting and months of waiting do not come into it, and the final fixed teeth are fitted in three clinical days. It is for mouths with a sound cortical layer and many missing teeth.

A removable denture

Still a valid option for patients who do not want surgery, or whose health does not allow it. But because there is no tooth root underneath, the bone carries no load; the loss carries on and the denture loosens over time.

What you need to know when making the decision

We are not writing this to frighten you, but so that you can ask the right questions, whichever clinic you go to.

A panoramic X-ray does not show thickness

A two-dimensional X-ray gives an idea of the height of the bone, but not of its thickness or the state of the hard outer layer. An answer given by looking at a panoramic X-ray alone rests on incomplete data; that holds for a 'no' just as much as for a 'yes'.

The loss does not stop by itself

In the area where a tooth was taken out, the bone keeps shrinking for as long as it carries no load. This does not mean you have to rush; it means the images you make your decision on need to be up to date.

The cortical layer is not the same in every mouth

The thickness and soundness of the hard layer this method relies on differ from jaw to jaw, and even between different areas of the same jaw. Two patients who come to us saying 'I was told I don't have enough bone' do not get the same answer.

An implant can be lost

As with every implant method, there is a chance of failure with this one too, and we tell you so from the start. Smoking, uncontrolled diabetes and neglected oral care are known to increase the risk.

Fixed teeth do not mean care is over

The gum around an implant can become inflamed too, and if that inflammation progresses, the bone around it is lost. Having fixed teeth does not exempt you from regular cleaning and check-ups; quite the opposite.

What to expect afterwards

The sequence below applies to patients treated with strategic implants. In a plan that includes a graft, healing takes longer.

Three clinical days
The examination, planning, surgery and the fitting of your final fixed teeth all fall within these three days. You leave the clinic with your final fixed teeth. Some swelling and tenderness during these days is normal.
The first week
The swelling goes down. We ask you to eat soft foods, keep away from hard and hot foods and brush the area gently. Any stitches are taken out during this period.
The first few weeks
We increase the chewing load gradually. Hard, crusty foods and habits such as chewing ice are put off during this period. Your gums settle into their new shape over these weeks.
Check-ups and the long term
We give you the check-up schedule and instructions for caring for the bridgework in writing. Interdental cleaning, regular professional cleaning and yearly imaging are what make this treatment last.

Message us right away if

The swelling increases after the third day. Swelling goes down as you heal. If it is increasing, we need to assess it.
A high temperature. A high temperature is a warning sign of infection. Call us without waiting.
Numbness that does not go away. Tell us about numbness in your lip, jaw or tongue that continues.

What determines the cost

We do not give figures on this page, because an accurate figure can only be given once the CBCT scan has been seen. Send us your images and we will set out the scope in writing, item by item. These are the items that determine the total:

Number of implants and which jaw: Whether it is one jaw or both, how many implants are planned and which areas they will be placed in determine the total directly.
Whether additional surgery is needed: If a graft or a sinus lift is needed, the scope widens. When this item does not apply, both the timeline and the total are smaller; we tell you whether it applies in your case after the CBCT scan.
Preparing the mouth: If there are teeth that need taking out, gum inflammation that needs treating or roots that need removing, these are added to the plan, and they affect the timeline too.
Bridgework: The material of the fixed teeth and the laboratory work have a direct effect on the total. We tell you the brand of the material we use in writing, from the outset.

Frequently asked questions

Another clinic told me 'let's graft first and wait for months'. Is that dentist wrong?

No. Looked at through the conventional implant method, that dentist is saying what is right within their own method. What we look at is different: whether the hard outer layer is suitable for anchorage. That measurement is not made in conventional planning anyway. Both opinions need to be discussed over the same CBCT scan; send us your images and we will give you our own assessment in writing.

I have worn a full denture for years and my jaw has resorbed a great deal. Can it be done for me too?

Yes. In jaws that have been without teeth for a long time, the side that resorbs is the spongy bone; the hard outer layer resists resorption and stays in place. In some jaws where the loss is advanced there is no surface left to anchor into; the CBCT scan shows that.

I have a panoramic X-ray. Do I have to have a CBCT scan?

It is enough for a first assessment; we will look at it and write to you about which possibilities are on the table. It is not enough for a treatment decision. A panoramic X-ray does not show the thickness of the bone or the state of the hard outer layer, and because this method rests directly on that layer, we do not draw up a plan without a CBCT scan.

I have diabetes, and I was told implants cannot be done for me.

Diabetes is not a barrier, and we carry out this protocol in patients with diabetes. What matters is whether your blood sugar is monitored and whether there is active inflammation in your mouth. If your blood sugar is unsteady, we get that in order first; skipping that step does nobody any favours.

I am missing one tooth. Can this method be used for me too?

There is a solution that suits you better. This protocol is for full-mouth cases and people missing many teeth; it is not an approach built for a single gap. When one tooth is missing, a conventional implant or, depending on the case, a bridge is more appropriate. Telling you that what suits you is not our route is part of our job too.

Do I really leave with fixed teeth in three days?

Yes. The protocol is built on three clinical days, and your final fixed teeth are fitted within those days. The examination and CBCT scan take place on the first of those days. You will also have some restrictions on chewing in the early period.

What happens if an implant does not take?

Losing an implant is a possible outcome, and we tell you so from the start. If it happens early on, we let the area heal and then assess it again. What would be done in such a situation is set out in writing in the treatment plan; we do not leave it to a verbal promise.

Why is there no price on this page?

Because two patients who arrive with the same sentence end up with very different plans: for one, a graft never comes into it, while for the other, preparing the mouth is a whole piece of work in itself. Any figure we wrote would either frighten you unnecessarily or change at the clinic.
