Sometimes, cases that look really easy to fix will turn out to be extremely hard due to a lack of bone in the place we are going to insert the implant.
Lacking enough bone in the jawbone can be a real drawback when we try to restore a mouth partially or completely. To avoid this problem, we can try regenerating the bone by either filling the hole left after the extraction or by regenerating the lost bone by means of bone grafting so that it gains enough thickness and depth for us to put the implant in place.
We can put a dental implant back in the same space the tooth was extracted from. This implant will prevent the bone being re-absorbed; if the implant is not placed in the socket, the process of bone re-absorption will continue.
The socket left after the extraction can be filled either at the same moment as the extraction or afterwards. For the bone grafting, we can use either small bones from the same patient or other materials. We also can use semi-permeable membranes to improve the healing process. The body will re-absorb the grafted material and the patient’s bone will take its place. This keeps the vertical and horizontal contours of the bone and produces little to no absorption.
If the implant is not put in place as soon as possible, the grafting will not work as expected and some bone will be lost. This can affect the size of the dental implant that was going to be put in place.
If the dental implants are put in place a long time after extraction, there will still be the problem of working with a smaller bone. The implants which can be put in place will have to be shorter and smaller in diameter. And if the dental implant is not put in place, the bone will keep on being absorbed.
Loss of Bone and Prosthesis
Without the stimulation of the tooth or of the dental implants, the bone will keep on being re-absorbed. 40% of the original bone mass can be lost during the first six months. The process of bone re-absorption can even be made faster if a prosthesis is used to replace the tooth and the gum tissue.
The more bone that is lost, the bigger the prosthesis will have to be to compensate for the loss of bone. And the longer this process goes on, the smaller the ridge will be and the bigger the prosthesis will have to be to make up for this.
