Bone addition is a procedure designed to help the body to produce bone tissue in the areas where the cheek bone has worn down due to old edentulous areas or infections.
This procedure is often used when preparing the implant insertion. The bone grafts are used when there is not enough original bone mass. They can be achieved through an autograft, using the bone material sampled from the patient or using artificial bone.
The bone addition procedure implies several stages: the dental surgeon lifts the gum to reach the cheek bone, where the addition material is place. After placing the bone material, it is covered with a protective membrane.
The graft area if left to heal for several months, then an X-ray is made to verify the success of the procedure. The bone addition can be successfully used for periodontitis, too.
The persons suffering from this disease have sustained severe losses at the gum tissue level and also at the level of the bone structure. Through regenerative surgery, the restoration of both the gum and the alveolar bone can be stimulated.
Bone additions and membranes
After losing a tooth, the alveolar bone, which supports the tooth, starts to wear down. Unfortunately, this process continues during the entire life if no interventions are made to consolidate it by means of bone graft(s).
What is bone augmentation (addition)?
This is a surgical procedure designed the increase the volume of bone substance by adding certain replacement materials. These materials are biocompatible from a biological, mechanical and functional point of view, so that bone regeneration can be fully guaranteed.
There are two types of biomaterials: additions materials and membranes.
These are differentiated according to their composition:
Autogenous or autologous materials – are bone fragments sampled from the patient.
Alogenous – bone fragments obtained from the bone tissue banks.
Heterologous or xenogeneic – bone fragments obtained from other species than the human one.
Aloplastic – synthetic material
Regeneration membranes are absorbable or non-absorbable protection barriers that protect the bone defect which has been rebuilt through addition.
