The qualifier in getting the dental implants is by having enough bone. When there is not enough bone, then a bone may get rebuilt. When there is not enough gum, this may be added also. The bone loss takes place after losing the tooth or by suffering chronic periodontitis. When someone suffers periodontitis, bacteria eat away the jawbone with the periodontal ligaments which connect a tooth at its bone.
The common reasons for a bone loss are when a tooth loss is not replaced, and it gets worse if the loss involved many teeth. Jawbone will be preserved because of the pressure and the stimulus from the chewing. When the tooth gets lost, the bone will be reabsorbed in the body. Within the first year of a tooth extraction, at least 25 percent of the bone will get lost and the loss will continue.
The bone loss takes place on a bone surrounded and which supported the tooth. This is called alveolar bone. Alveolar bone does form a ridge and this is where the teeth get embedded. Such ridges will atrophy horizontally and vertically.
By replacing the teeth using partial or full dentures, it will not solve this problem since there is no pressure used from the denture to the bone as it happens with natural teeth. If there is a removal of molars at upper jaw, then more resorption may take place because of the expansion of the sinus cavity. If there are no teeth in the place, the air pressure within the sinus cavity may cause the resorption of a bone lining over the sinuses.
The bone loss may also be a result of the misaligned teeth and it creates a situation for which the normal chewing will not take place and this cause the loss of a needed stimulus on a bone. The bone may be lost if there is an infection which damages it. When there is a large tumor at the face, it will require its removal and parts of a jaw.
Bone loss with dentures
Dentures can accelerate the cases of bone loss through wearing the ridges away of a bone where it had been put. Whenever a person bites down or if he clenches at the teeth, there is a pressure at the ridge and it results in resorption. It is the reasons why there is a continual problem when getting the dentures in fitting, difficult and painful chewing and sore spots. A person who has denture may experience a severe consequence of a bone loss and it is called collapse of a lower third of his face.
Because of the financial problems, some people may have lost their tooth and they choose to restore it using removal of particle dentures. This is a tool that helps to restore the function and some degree of the aesthetic appearance. However, it is better to improve the appearance and the function of the tooth using dental implants. When it comes to replacing a tooth, a dental implant is the closest technology that a person may use. However, there can be some roadblock to the implants, and this is mostly when there is too much time that passed between the time a person lost the tooth and the time he wants to get the implant.
Roadblocks to the Implants
Inside the implants, there is a post made in titanium metal and it is embedded into the jawbone surgically. The titanium will attract the bone cells naturally and it grows and adheres to it. So that it can support a porcelain crown or dentures and bridges over it. However, in order to get the natural appearance required. It is good that the implant is put in the best location. To do this, the bone should be enough.
In case the tooth had been missing for some time, forces which are generated while chewing, they will travel to go to the jawbone and it will stimulate the bone growth. When the stimulus is not around, since there is a missing tooth, the new bone cells will not replace the older ones according to a healthy rate so total bone volume will get lost. The denture will not compensate such needed pressure.
If the implants cannot be placed because there is not enough bone, then a bone graft can be used instead. A graft will work like the scaffold of new bone cells where they can grow on. This can produce the right level of bone that can support the implants. When the bone deficiency is not worse. Then the bone graft with the implants will be placed at the same time.
When a person suffers a bone loss. The doctor will determine first the level of bone loss at the missing tooth site. And check if the bone grafting is the right option. The bone grafting will postpone the implant but the delay is required for successful results. When the bone volume is increased, then the implant will be better compared to other restoration methods.
How to prevent bone loss
The bone loss should be prevented through the use of the replacement tooth. And a root which will use the same pressure like natural teeth. This is done at once after the extraction of the tooth. And the placement of a dental implant through the use of a denture or a bridge supported by the implant.
A dental bridge or a single tooth which is supported by the implants, it will offer at least 99 percent of the force found with the normal tooth.
If it is the upper back teeth which had been removed. Then a ridge bone gets reabsorbed so the sinus cavity will expand. This is a bone that separates the sinus cavity with the oral cavity will become too thin. The dental implants are not installed using such thin bone. So the dentist will push up the lining of the membranes away of the jaw. And packs a bone graft material through the sinus cavity. After the bone graft material had integrated fully with a jaw bone, the implants will be placed.
