Wisdom tooth surgery
Third molars, also known as wisdom molars, are the last teeth to erupt and are positioned at the end of the mouth. Sometimes they never erupt due to lack of space to position themselves in the dental arch.
They erupt between 16 and 25 years of age, most people have four wisdom molars, sometimes people do not develop them at all or only the upper or lower two. The function of wisdom molars is considered to be lost in evolution.
Wisdom molars have to be removed with oral surgery when they present a danger of developing cavities due to bacteria that can get trapped between the two teeth and can affect the adjacent tooth, or when it ¨eats¨ the root of the adjacent tooth to take up its space, causing the tooth to lose its function.
A sinus lift is an oral surgery that adds bone to your upper jaw. The bone is added between the jaw and the maxillary sinuses, which are on either side of your nose.
A sinus lift is done when there is not enough bone in the upper jaw, or the sinuses are too close to the jaw, for dental implants to be placed.
This can be due to the following conditions:
- People who have lost teeth in their upper jaw, particularly the back teeth, or molars, do not have enough bone for implants to be placed.
- When gum disease caused bone loss.
- Another reason to bone loss is tooth loss. Once the tooth is gone, the bone begins to be absorbed back into the body. If the tooth wasn’t replaced on time and it has been missing for a long time, there will not be enough bone left to place implants.
Bone augmentation or bone graft is a procedure that involves adding bone or bone like materials to the jaw in order to be able to place dental implants.
If a person does not have enough bone where a tooth has been extracted or has been lost, a dental implant cannot be placed because it will not hold in the jaw.
A patient will need a dental implant to replace a missing tooth, whether it was extracted or it broke some time ago or if it needs to be extracted and replaced immediately. The doctor will determine whether or not there is enough bone to place the implant, however, in most cases, the bone augmentation oral surgery is necessary.
There are four types of bone grafts that are most commonly used:
- First, there are autografts (or autogenous grafts), in which the bone is taken from the patients own body, usually from the chin in dental procedures. This type of bone graft has proven to be the most successful, since there is no other graft as compatible.
- There are also allografts (or allogenous grafts), which are taken from human donors, and are converted by the patients own bone into natural bone. They undergo numerous controls and sterilization processes; they are often chosen to avoid a second surgery procedure other than the implant placement.
- Then, there are xenografts, or bone augmentations taken from animals, most commonly from cows. These go through strict processes in order to become biocompatible and sterile for future use.
- Lastly, there are alloplastic grafts, made from artificial or synthetic materials, either calcium phosphates or hydroxy apatite, that stimulate the patients body to form natural bone. Alloplastic grafts have the least success rates of all the types of bone augmentations; however, it is the one with least probabilities or risk of infections.
- Bone augmentation offer patients who have had extractions the opportunity to create an area filled with bone or bone like materials in order to place in dental implants or to restore defects in the bone. They are very successful and it is an excellent option for being a good candidate for implants or any other dental restoration procedure.
