In the clinic we often see patients who arrive worried because they have been told they do not have enough bone for dental implants in Alicante.
It is frustrating and discouraging, especially for those who have gone years without teeth or have recently lost some. The good news is that lack of bone is no longer an insurmountable obstacle.
Today’s techniques make it possible to place dental implants even where bone is insufficient or of poor quality.
Why the jawbone shrinks
Many patients wonder how they can be short of bone when they have never had serious problems. The reality is that the jawbone naturally shrinks when we lose teeth.
Bone needs constant stimulation to maintain itself. When we chew, the tooth roots transmit forces that stimulate the bone tissue.
When a tooth is extracted or lost for other reasons, that stimulation disappears and bone resorption begins.
Main causes of bone loss
Bone loss in the jaws can be accelerated by several factors:
- Time without teeth. Every year that passes without replacing a tooth, the bone keeps shrinking. Patients who have worn removable dentures for decades usually have severe bone atrophy.
- Gum disease. Chronic gum infections progressively destroy the bone that supports the teeth. Bone loss is often the final reason for an extraction.
- Trauma and fractures. Heavy blows can permanently damage the bone structure.
- Prolonged dental infections. Abscesses and periapical cysts erode the surrounding bone, leaving significant defects after extraction.
What “dental implants without bone” means
When we talk about “dental implants without bone” we really mean placing implants in patients with little or no bone available, without a large graft (or even avoiding grafts altogether).
The term “implants without bone” can be confusing. In reality we always need some bone to anchor an implant, but there are techniques that let us regenerate bone or make use of alternative bone areas.
When we talk about implants without bone we mean two main approaches:
- Bone regeneration techniques that increase the volume available.
- Special implants, such as zygomatic implants, which are anchored in the cheekbone.
The key is a three-dimensional study with a 3D dental CT scan, which lets us measure the available bone to the millimetre and plan safely.
Techniques available when bone is lacking
There are now many options for placing implants with little bone, and they are increasingly predictable.
Dental bone graft
A dental bone graft involves adding bone material to the deficient area to increase its volume.
It can be:
- Autograft (from the patient’s own body)
- Allograft (from a tissue bank)
- Xenograft (treated animal origin)
- Biocompatible synthetic materials
At our dental clinic in Alicante we mainly use xenografts and latest-generation biomaterials, with excellent success rates and less morbidity.
Sinus lift
A sinus lift solves the lack of bone at the back of the upper jaw. The procedure involves lifting the sinus membrane and filling the space with graft material to gain bone height.
There are two techniques:
- Open or lateral lift, when there is less than 4 to 5 mm of bone.
- Closed or transcrestal lift, when we have 5 to 7 mm and can place the implant in the same procedure.
It is a technique with more than 30 years of scientific evidence and very high predictability.
Guided bone regeneration
Guided bone regeneration (GBR) uses special membranes to protect the space where we want new bone to form.
The membrane stops the gum from invading the defect, allowing bone cells to regenerate the area in a controlled way. It is especially useful for localised defects or after complex extractions.
Angled implants (All-on-4 / All-on-6)
When bone is lacking at the back (especially in the upper jaw or an atrophic lower jaw), a very useful option is to place angled implants to make use of the bone you do have further forward, where it is denser, avoiding anatomical structures such as the maxillary sinus or the dental nerve.
In practice this is widely used in full-arch rehabilitations such as All-on-4 or All-on-6, where we place 4 or 6 implants (some of them tilted) and attach a fixed prosthesis.
In selected cases it can also allow immediate loading (fixed teeth in a short time), provided the implant stability and the planning allow it.
Zygomatic implants: the advanced alternative
Zygomatic implants are a solution for cases of severe atrophy of the upper jaw. Instead of regenerating bone, they are anchored in the zygomatic bone (cheekbone), which does not shrink after tooth loss.
In many cases they allow immediate loading, with fixed teeth fitted within 24 to 48 hours.
Advantages of zygomatic implants
- Drastically shorter treatment time
- They avoid extensive grafts
- Success rate above 95%
Limitations
- They require advanced training
- Not every patient is a candidate
- Slightly more intense recovery
Which technique is best in each case?
There is no one-size-fits-all solution. The best technique always depends on several key factors: the amount and quality of the remaining bone, the exact location of the defect, your general health, your expectations about treatment time and, of course, your budget.
That is why, before deciding, it is essential to carry out a personalised study that lets us weigh up all these variables and choose the safest, most predictable and most suitable option for you.
Process and recovery time
We start with a first consultation including a three-dimensional dental CT scan, where we analyse your case to the millimetre. Then we design a treatment plan tailored to you.
Surgical phase
Surgery is carried out under local anaesthetic, and where needed we offer conscious sedation. Recovery is usually mild to moderate depending on the technique used.
Osseointegration phase
After grafts, the maturation period is between 6 and 9 months. With immediate loading techniques the process is significantly shorter.
Prosthetic phase
Once the implants have integrated, we fit the final prosthesis. With it you get back function, appearance and quality of life.
Having little bone does not mean giving up on implants
Dental bone loss is common but solvable. Thanks to advanced techniques such as bone regeneration, sinus lifts and zygomatic implants, today we can rehabilitate practically any case.
The essential thing is an accurate diagnosis with a 3D CT scan and choosing the most suitable technique for you.
At our dental clinic we combine experience in advanced implantology, latest-generation technology and a personal approach to offer real solutions when you have been told you do not have enough bone.
If you have been told you are not a candidate for implants, do not give up without a second opinion. You can quickly request your full assessment through our website or write to us directly on WhatsApp. Many of our patients come from the UK, where the same treatment costs considerably more.
