Teeth can be extracted for a number of reasons.
In most cases the teeth are removed when they become movable, in case of infection or trauma. When a tooth is lost, the supporting jaw bone begins to be absorbed (to melt). Usually, the bone melts horizontally by 25% during the first year, and later the pace of bone loss slows down. Over time, the bone melts also vertically.
This bone melting can become a serious problem in tooth reconstruction, as well as the patient’s aesthetic appearance.
Replacement of a tooth requires a thorough examination of the patient and it is necessary to make a comprehensive treatment plan, in order to preserve as much bone material as possible. If the patient has lost the bone in the vertical dimension, tooth replacement with dental implants at this stage may not be possible because there is not enough bone material (not to mention subsequent procedures).
Loss of bone thickness makes it more difficult to perform tooth implant prosthesis because this method requires the bone to be stable.
There are many procedures for successful restructuring of the resorbed bone, but it is always easier to try to maintain your own bone, until this is still possible.
In order to preserve as much bone as possible, and where circumstances are favourable, surgeons of Kaunas Centre Implantology Oral attempt to remove tooth without lifting the gums, which is less damaging to the bone, i.e. using atraumatic extraction technique. However, even with an excellent non-traumatic extraction, the bone will begin to decline over time. There are several ways to help preserve the bone structure during the tooth extraction.
Artificial bone placing in the empty tooth alveolus can help maintain the bone mass. Bone substitutes come in different types. Membrane is often used as a barrier in order to keep the bone substitute in its place, at the beginning of grafting, and for better assurance of bone formation.
It is important to note that the bone preservation is only temporary.
After about 6-9 months they alveolar bone resorption begins, therefore the tooth should be implanted before it.
This technique is most often applied when implantation is planned not immediately or after 1-3 months, but later, after 6-12 months.
This technique is used in order to protect as much of the alveolar bone as possible from resorption.
