Before dental implants, a bone examination is important as the implant needs stable long-term funds – bones need. In some cases, the bone of the patient’s jawbone may not be suitable for the implantation due to individual reasons.
The question arises, how should I know, if I need bone grafting? First, we take a panorama X-ray, which our dentists examine and tell what kind of treatment is suggested for the patient. If the bone tissue is not suitable for implantation, dentists may recommend bone grafting.
The bone grafting is an oral surgical intervention when existing bone mass is filled with bone grafting material, which incorporates over time, and this could safely be implanted with the artificial tooth root.
How could be my bone inappropriate?
There are two types when bones are not suitable for implantation:
1. cause: bone-loss
2. cause: chronic periodontitis
Due to the formation and spread of inflammation bacteria slowly digest the bone and spread to the focal point. This leads to thinning the bone, which has consequences on the jaw and the adjacent teeth.
However, the most common cause is tooth loss itself. The jaw needs to be continuously stimulated by chewing.
If a tooth drops and does not get replaced, the bone tissue on that territory begins to absorb over time as it’s no longer under pressure and has nothing to hold. This absorption happens every time, but level of bone loss is determined only by time. The later you replenish your teeth, the greater the chance will be for an osteoporosis.
Bone loss affects the environment of the missing tooth too. Due to bone thinning, adjacent teeth may loose, move, or even shape the visual appearance of the person (due to jaw bone mass change).
Steps of bone grafting
After the preliminary examination, the bone grafting could begin. This can be done in the majority of cases in local anesthesia. Anesthesia may be required if bone absorption is significant in the area of the buckle and the bone has to be replaced by bone tissue removed from the other part of the jaw.
Bone grafting requires a period of 30 to 90 minutes, depending on the local anesthesia or the type of material.
The bone grafting can be performed with three different types of material. During the process, oral surgeons lift the bones with artificial or natural materials.
Bone Grafting with Special Bone Grafting Materials
Artificial bone grafting material
The artificial bone replacer is synthetic, is made of alloplast, which contains mainly hydroxyapatite, which is completely biocompatible as it is a natural component of the tooth itself. This material is injected into the desired area. Over a short period of time, it becomes healed and becomes a solid bone in which our oral surgeons can safely implant.
Natural bone grafting material
The natural bone substitute material contains disinfected bones of animals, enriched with appropriate minerals. Thanks to the added ingredients, the material adapts to the patient’s bone and grows in the hole until it finally fills it.
The third type of bone replacement differs significantly from the previous two. In case of bone grafting, oral surgeons would remove a single part of the patient’s own bone (eg from the hip, tibia, skull or jaw) and supplement the missing part. We do not recommend it at the MDental Clinic Hungary.
In most cases, an absorbent membrane is used to cover the bone substitute material to create the best possible environment for tissue regeneration.
The bone replacement substance becomes part of the surrounding area and becomes part of the body during 6-8 months.
Is the material used for bone grafting safe?
We use premium quality Geistlich bone grafting material at our dental clinic. This is very similar to the human bone, thus ensuring perfect integration, bone formation, and the wished quantity. 100% biocompatible, non-toxic, does not harm the body and does not provoke any tissue reaction
Bone grafting, like any other surgical procedure, may have a health risk. A possible infection may be responsible for the replacement of the replacement material and the implantation should not occur.
Replacement of the jaw by surgical bone surgery allows the bone to be repaired in large areas. Thanks to the modern bone grafting methods, nowadays almost any jaw bone can be replaced to provide the basis for one or more implants.
First image: the bone is too thin by the reason of its resorption to support a dental implant.
Second image: bone grafting material is added to the bone and needs 6-8 months to heal.
Third image: the graft integrated with the bone and it is ready to implant.
A special type of bone grafting: sinus lift
A special case of bone grafting is the so-called sinus lift. We can talk about this case if the bone is not suitable in the upper jaw to support a dental implant by reason of its inadequate thickness. In this case, our dental surgeons fill the area (between the upper jaw and sinus) with the bone substitute material.
In order to have enough space for the bone, the sinus should be raised inside. Although it sounds horrible, it is now a routine intervention in the field of oral surgery.
The cost of bone grafting
In the case of bone implantation when bone grafting is needed, it definitely adds an additional cost to the treatment. The cost of bone grafting can be found here.
