Extractions trigger the process of bone resorption. In the first year, the body loses around 25% of the initial bone volume, after that the process is slower, but continuous. If we want to insert an implant into the new cavity, bone augmentation is mandatory, because the stability of a dental implant requires a certain height and width of the bone.
ARTIFICIAL BONE – THE BUILDING BLOCK OF AUGMENTATION
Augmentation is done in the same session as implant insertion, if the situation allows it. It can be done as long as there are no local infections, to repair minor defects. If the process is gradual, then we first make the bone augmentation, and after a few months, we can insert the implant.
Bone augmentation is a complex procedure, but has good, predictable results. As with any dental surgical procedure, a local anesthetic is administered. After surgery, the patient must follow a treatment composed of antibiotics, anti-inflammatories and pain killers, and for a faster gum healing, we recommend disinfectant and healings gels.
ARTIFICIAL BONE GRAFT
The augmentation process requires a bone graft. We use the patient’s own bone (autogenous) and/or artificial bone. The bone grafts we use are Bio-OSS, MAXgraft and Cerabone. They are bovine bones and especially treated to remove any organic matter. All that’s left is an inorganic matrix of bone characteristic minerals. They lack specific cells. For this reason, contamination or rejection are impossible. They are a very reliable matrix that the body uses to create new bone where it was missing. The patient’s cells start to populate the artificial bone graft turning it into new and resistant bone. The artificial bone is colonized in stages, growing by around 1mm each month. The newly formed bone needs an additional 2 months for a full mineralization.
