The implantation of new teeth is the most effective, state-of-the-art method used for tooth replacement. Patients can acquire new teeth that are similarly-looking and almost as strong as their natural ones. However, even this method cannot be effective if the jaw bones are not suitable to be carriers of the artificial roots. In this case, dental experts apply jaw bone augmentation procedures.

The condition of the jaw bone is crucial in dental implantation . The implant may only be implanted into bones that have adequate height and width. These bones are able to accept, fix and persistently carry the artificial root. In certain cases, the jaw bones have to be treated before the implantation. We are now going to discuss these cases, and list the different jaw bone augmentation procedures.
When is a bone graft in the jaw necessary?
It is recommended that the augmentation of the artificial roots is carried out at or around the same time when the patient loses their natural teeth. In most cases, the sufficient amount of bone is still available in this period. This ideal condition, however, becomes gradually worse in time. In the place of the missing tooth the pressure on the jaw bone disappears, resulting in bone atrophy and the thinning of the bone. In the case of the upper jaw bones, the sinus is “pushing” downwards, in the direction of the oral cavity. After a longer period of time, the jaw bone becomes too thin for an implant to be inserted into it, because of the potential danger that the artificial root’s edge damages the sinus. This is one of the typical cases when a so-called sinus lift – and at the same time, the replacement of the missing bone – is necessary. Bone augmentation may too be necessary when the jaw bones are not wide enough to attach the implant.
There might be several further reasons for the reduction in bone material. For instance, an accident when part of the jaw bone is fractured, gum diseases or bone atrophy caused by other diseases can all be responsible. The size of the sinus increases with age, and its osseous wall becomes thinner, so at a later age bone augmentation could be more frequently necessary before the insertion of the implants.
Methods applied and materials used
The most common augmentation method usually involves sinus lift. The dental surgeon lifts the soft tissues on the sinus base, and fills the space revealed with bone graft material. This way they can lift the upper jaw bone which is then able to accept the implant. This procedure can be performed in two different ways:
In case of a closed sinus lift, the sinus base is accessed through tiny drill-holes from the place of the missing tooth. Bone graft material is placed in the empty space after lifting the soft tissues. This procedure allows for a lower extent of sinus lifting than the open method. In the latter case, the dental surgeon accesses the jaw bone by opening the gums . A window-shaped incision is made on the gum, through which the sinus base can be accessed and the bone graft material can be inserted. The extent of sinus lift reached by this method may be more significant.
Recovery time after jaw bone augmentation is three to nine months. This is the time required for the bone graft material to solidify, and to unite with the existing bone. The duration may depend on:
• types of materials used
• individual condition of the patient
• condition of the immune system
There are a great number of materials that can be used during the procedures, so it is better to classify them by their origin. We distinguish the following bone graft materials:
• Autogenous bone substitute
• Allograft bone substitute
• Xenograft bone substitute
• Alloplastic bone substitute
We are now going to list these materials and explain their production as well as their influence on jaw bone augmentation.
Bone chips required for augmentation is obtained from the patient’s own bone tissues. In most cases, the bone material is harvested from the area of the hips. The autogenous procedure’s main advantage is that an implant rejection is unlikely, that is, the body will not reject the materials that had been implanted. Its disadvantage is that the patient has to undergo two surgeries. One intervention is necessary for obtaining bone material, while this material is inserted into the jaw bone during a second surgery.
Allograft bone, which is bone material obtained from a different donor other than the patient, is available from “bone banks”, similarly to the way blood is available in “blood banks”. Bone material is harvested from human bone released during the process of hip replacement surgeries. This material is cleaned, sterilized and inspected. Then it is reformed into material that is applied, amongst several other uses, in jaw bone augmentation. Beside the autogenous bone, this is considered the most ideal material as there is less of a risk that the implant is rejected by the body. However, the healing and the ossification period may take longer than in the case of the autogenous bone.
This solution is recommended for patients who:
• would like to avoid having to undergo two surgeries
• dislike the idea of bones of animal origin
• dislike the implantation of fully synthetic materials
During Xenografting, bone is harvested from bones of animal origin, usually from cow tissue. Some patients have a strong dislike against such materials, even though the method involves no risk. Animal bone tissues are inspected thoroughly multiple times before they are cleaned and sterilized. The bone graft material is only harvested after this process.
Alloplastic bone materials made from calcium phosphate imitate natural bone tissues very well. Also, they can be applied for the human body safely. Their great advantage is that they are available in the sufficient quantity. Thus, they make the use of animal or human donors unnecessary for the jaw bone augmentation procedure. With the use of alloplastic bone materials, we can exclude human or animal infection completely. However, their great disadvantage is that the human body might be more likely to reject them.
