Nowadays, the modern dentistry wants to restore the mouth of the patient to achieve to the normal aesthetics, comfort, and function after atrophy, injury, and disease that take place in the oral environment. If a patient is missing many teeth, then this goal will not be achieved easily by using the traditional dentistry. However, with the use of advanced implant technique, it is easy to avoid bone loss and achieve predictable success with rehabilitation even if the situation is challenging.
Tooth loss effects
Body bones work in the same way as the muscle. If you exercise the muscle, then it will grow to become larger and stronger. If you stimulate and also exercise the bone, it will become even stronger. When the bone is not working as it generally does, it will become weaker and not that dense. This is why a bone jaw should be stimulated with implants or a natural tooth. An implant and the tooth are meant to create and to preserve the shape and the size of a bone. The bone has to be stimulated in order to preserve strength, density, and its form. The studies had found out those normal chewing forces which have to be transmitted from one tooth to another. It will preserve the bone and it keeps it even stronger.
Such close relationship found between the bone and the tooth, it will continue for the entire life. In case the tooth gets lost, such lack of the stimulation on a surrounding bone, it will read to decreased density and the dimension of a bone. It means the loss of the height and width of a bone. This is why the tooth is important for the stimulation of the bone in order to maintain the strength, shape, and density.
Losing the bone after tooth loss takes place slowly but in the end, it will also affect the bone and it can lead to the complete bone loss. You can find the lower jaw on two inches in its height. And it may be reduced to achieve one-quarter of an inch because of atrophy. This is one of the reasons why the modern dentistry had become excited to the dental implants in order to stay in the place of missing teeth.
Bone loss risk after a tooth loss
Patients who wear the dentures, they will not realize that they do lose the bone after some time, such poor function and poor fit of dentures; many people believe it to be the results of weight loss or age of a patient or a wear of teeth on the dentures. The amount and the rate of the bone loss can be influenced by parafunction such as grinding the teeth, medication, metabolism, hormones or lack of the estrogen which causes the bone loss, hormones, and gender since females tend to lose more bone compared to men.
In past most people ignored the problem of the bone loss because of the tooth loss. And traditional dentistry did not care too much about it. However, the reason for this is because the dentists had no option of preventing the problem of the bone loss with the consequences. This is why the dentist was ignoring anything about tooth loss and the bone loss that takes place afterward. By now, the dentists are aware of bone loss and how implants may stop the bone loss. Since they will stimulate bone, in the same way, it happens with a tooth before the extraction.
How to deal with bone loss
Jaws and bone loss are known to be associated with many problems. And also for they impair predictable results for the traditional dentures. Loss of a bone will result in the decreased bone width. There is at least 25% of the decrease of the width with the bone in the first year of the tooth loss. And in general, there is a decrease in the height in the first year after the extraction of many teeth.
The leftover narrow bone will cause the discomfort if there is a thin overlying tissue loaded under partial or complete dentures. There is nothing that may prevent the denture against moving against lower lip while speaking or doing other functions. This problem can also increase by the upward movement at the back of a denture if there is a contraction of a muscle during function or speech. The slope found on a lower jaw when compared to that of the upper jaw. It will create instability with the movement of the lower denture.
You cannot limit Loss of bone at the lower and upper jaw to the teeth area only. There are portions of a skeletal bone which a patient may loose mostly at the back parts of a lower jaw. And this is where the patient can lose at least 80 percent of their bone. Nerves at the lower jaw that surround the bone and the bone in return protect them. They will expose and they will sit at the top of a ridge under the denture.
This will lead to permanent or temporary loss of area sensation and acute pain. Bone loss at the upper jaw can lead to the pain and it will increase upper denture movement while eating. If a person uses too much force while using ill-fitting denture, this force happens only at the root surface and not at the internal structure of a bone because there is no root in it. Such force will not stimulate or maintain the bone. But it will decrease the blood supply which will increase bone loss rate.
Bone loss effect on the appearance
The facial changes take place naturally because of the aging process. When a patient loose a tooth, then such process will accelerate and the face will age faster. When someone loses a tooth, then this will add at least 10 years to his face. There is a decrease in face height which takes place if a patient loose his bone height. It will lead to many facial changes. There is also a decrease of an angle at the lips. And deepening of the vertical lines at the lips which can create an even harsher appearance.
