How to preserve the jawbone after a tooth extraction?
During a tooth extraction procedure, the blood vessels around the tooth rupture and the alveolus (the tooth socket) fills with saliva and blood, from which a blood clot forms.
The bone wound caused by a tooth extraction procedure takes two months to heal. Proper ossification is ensured by a well-preserved height of the alveolar bone and an appropriate density of the newly formed bone.
Clinical studies show that:
- after a tooth extraction procedure, a severe alveolar bone volume reduction occurs due to the bone and soft tissue resorption,
- two-thirds of the affected tissues undergo some degree of resorption during the first three months.
It is primarily the bone facing the cheek which resorbs very quickly, which may cause several problems.
If we replace the missing tooth with a bridge restoration procedure, a gap can form between the bridge and the underlying gums, since the gums are attached to the jawbone and recede as the bone resorbs.
The formed gap does not look attractive and makes dental hygiene difficult as food particles can accumulate in the gap causing inflammation of the gums.
Placing an implant may stop the bone loss, but an extensive bone augmentation procedure must be carried out first to ensure that the implant is completely surrounded by bone.
Failing to build up the bone can lead to poor aesthetic results. It is, therefore, worth the effort to ensure that the contour of the jawbone is retained as much as possible when teeth are extracted. Bone augmentation can be achieved by using special bone substitute materials, such as Geistlich Bio-Gide, to fill the alveolus.
If necessary, the protective membrane is also used, such as Geistlich Bio-Gide, to protect the wall of the alveolus, which is often damaged during the tooth extraction procedure. The protective membrane protects the damaged area, promotes undisturbed bone regeneration and supports wound healing.
The natural structure of the Geistlich Bio-Oss serves as a scaffold for new bone formation. After four to six months, Geistlich Bio-Oss is intermingled with new bone and is then included in the natural remodelling process of the bone.
The natural contour of the jawbone can therefore be retained and with that a beautiful aesthetic appearance, as, consequently, the gums do not recede either.
The bone augmentation procedure can be observed in the following video:
In our dental office, we use both Geistlich Bio-Gide and Geistlich Bio-Oss, which are the most widely used bone regeneration materials worldwide. The products are scientifically documented in several hundred studies and have been used in millions of patients.
