Surgical Treatment for Jaw Disorders

Normally jaw is made up of a set of bones. It consist of two parts, upper portion of the jaw is maxilla and is immovable and lower portion of the jaw is mandible which is involved in the movement of jaw.

Jaw disorder is the condition in which abnormalities in the jaw position takes place. Minor abnormalities in the jaw can be treated by wearing dental braces and some other appliances. If the abnormalities in the jaw cannot be treated with dental braces, then it can be treated by performing surgeries.

Corrective jaw surgery
Corrective jaw surgery is performed to correct the abnormalities in jaw. It is performed to correct the deformities in the upper or lower jaw or both the jaws. It improves the appearance of face and also improves the chewing and talking ability.

Corrective jaw surgery is performed on candidates who are:

 

  • Experiencing difficulty in chewing or talking
  • Deformities in temporomandibular joint
  • Prognathism and malocclusion
  • Breathing through mouth
  • Receding lower jaw and chin

Surgery can be performed on candidates whose jaw bone has fully developed and there is no growth in the jaw. Surgical procedure involves following steps:

  • Pre operative treatment: In this step, orthodontist takes x-rays to examine the jaw and align your teeth using dental braces. These braces should be fitted to your teeth for several weeks before surgery. This will gradually push your teeth to their normal position.
  • Surgical procedure: Surgical procedure starts initially by giving general anesthesia.
  • ¬†Lower jaw surgery: In this surgery an incision is made inside the mouth to expose the joint potion of the jaw connecting to the front portion that supports teeth. Then deformities are corrected and repositioned the lower jaw to their normal position. Small surgical plate and screws are used to hold the jaw in their normal position.
  • Upper jaw surgery: In this surgery, an incision is made inside the mouth to separate the tooth baring portion of the jaw from its base. Corrections are made by removing or reshaping or adding of jaw tissue to relocate in the normal position. Then tiny surgical plate and screws are used to hold the jaw in new position.
  • Post operative treatment: Recovery time is 4-6 weeks. After completion of surgery, retainers are applied to the jaw to prevent the repositioning of jaw. Orthodontist suggest you to take liquids or soft consistency foods for some weeks.

Side effects of surgery

How Does Smoking Leads to Gum Problems

Smoking and chewing tobacco products causes gum problems. The severity of risk depends on the frequency of these products you use. More you smoke and chew tobacco products, the more will be the risk of gum problems.

Tobacco products contain nicotine and nitrosamines which are harmful and causes dental diseases and some times leads to the risk of oral cancer. In this article we will discuss how smoking and chewing tobacco leads to gum problems.

Affects the bone and soft tissue
Smoking and chewing tobacco interfere with the attachment of bone and soft tissue to the teeth. Formation of pockets between the teeth and gum leads to the build up of plaque and leads to gum problems.

Interfering with functioning of normal cells
Smoking and chewing tobacco products interfere with the normal functioning of gum tissue cells and are susceptible to gum diseases.

Reduces the flow of blood
It reduces the flow of blood to teeth and gum. Therefore the oxygen and nutrients are not supplied to the gum tissue and gums become inflame and swollen. This creates gap between the teeth and gum, and builds plaque which later leads to gingivitis. If it is untreated, condition becomes worse and leads to periodontal diseases.

Reduces saliva secretions
Smoking and chewing tobacco reduces saliva secretions in mouth. Saliva helps to remove the debris in mouth to protect from dental diseases. Decrease in the saliva secretions makes the mouth dry and there is bacteria growth which leads to gum problems.

Irritates gum tissue
Chewing tobacco contains toxic chemicals that irritates the gum tissue and therefore receding of gums takes place. Therefore root becomes exposed and becomes sensitive to hot and cold. This in turn leads to infection to gum tissue.

Smoking and chewing tobacco not only increases risk for gum diseases, but is also responsible for dental problems like tooth decay, discoloration of teeth, sensitivity to hot and cold, and oral cancers.

Many of these problems can be cured, but the best way of treatment is quitting smoking and other tobacco related products.

How Radiation Therapy is Helpful in Oral Cancer

Radiation therapy involves using radiation for curing difficult diseases such as cancer. Radiation therapy involves high energy radiation used to destroy cancer cells. It is effective for treating small tumors where surgery is not required to cure. It is also used in combination with surgery. After surgery, radiation therapy is used to destroy if any cancer cells left in oral cavity. Radiation therapy destroys both normal and cancer cells but normal cells gets repaired by themselves.
Prior to the radiation treatment, CT scanning is done to:

  • Measure the size of tumor to decide the dose of radiation required for treatment.
  • Give the exact position of the the tumor where radiation therapy is needed.

In radiation therapy, the complete dose of radiation is break down into small segments and given in regular intervals. This gives the time to repair normal cells and also prevents discomfort to patient.

Types of radiation therapy
Radiation therapy are classified into following types.

1. Based on the type of radiation given:

  • X-Ray radiation
  • Gamma radiation

2. Based on the position of radiation:

  • Internal radiation
  • External radiation

X-Ray radiation:
In this technique, the source of radiation is X-rays. X-rays are the first form of radiation source. The equipment that produce X-rays as radiations are linear accelerator and betatron. Depending on the amount of energy produced, X-ray radiation is used to destroy cancer tumors. The more energy produced, the deeper will be the penetration of X-rays. This has fewer side effects as the radiation is limited to particular area.

Gamma radiation:
The effect of this radiation is same as x-ray radiation but here gamma rays are used as a source of radiation. In this gamma rays gives radiation spontaneously as they decompose.

Internal radiation:
Internal radiation is also called brachytherapy. It uses radio active materials to deliver radiation directly to the cancer cells. Radio active materials includes tubes or seeds. Radioactive substances are passed into these tubes. In some cases radio active pellets are placed directly on cancer cell. These can be removed after completion of radio therapy.

Prior to this radiation general anesthesia is given to prevent discomfort to patient. Then x-rays are taken to ensure that they are placed in a appropriate position. The advantage of internal radiotherapy is it has less effect on other parts of body as it directly given to tumor.

External radiation:
In this, a beam of radiation is delivered from machine to cancer cells from outside of the body. This is similar to taking x-ray but patient exposed to high radiation. Now a days advanced techniques in external radiations used are 3 dimensional radiation therapy (3-D CRT) and intensity modulated radiation therapy (IMRT).

Prior to these techniques, CT scanning or MRI scanning was done to locate the cancer position. Then, radiation is sent from various angles to the cancer site. This lowers the effect of radiation on other parts of the body.

Radiation therapy is used alone if the tumor is small and can be cured where surgery is not required. Radiation therapy in combination with surgery to destroy if any cancer cells left out after surgery.

Reasons to Remove Wisdom Tooth

The third molars are also known as wisdom tooth and are the last adult teeth to erupt. Some people are not affected by wisdom tooth eruption while some develop painful conditions that require removing (extracting) of tooth. In this article, we will discuss the reasons to remove wisdom tooth.

Reasons to remove wisdom tooth:

  • If the wisdom tooth is erupting in a wrong, tilted or twisted position.
  • If wisdom tooth does not have enough space or room to emerge and are trapped below the gum line.
  • If the wisdom tooth is pushing the front tooth (second molars) and causing pain.
  • The erupted wisdom tooth that has already erupted lacks good oral hygiene as it is difficult to reach the last tooth/teeth resulting in tooth decay.
  • The chance of complications necessitating removal of wisdom teeth increases with age.
  • In very rare condition, the impacted wisdom tooth develops cysts. Removal of such cysts require complicated and extensive procedures.
  • Wisdom tooth sometimes may contribute to crowding of front/nearby teeth.
  • Even if the wisdom tooth appears to be problem free, it remains a breeding ground for the oral infection and inflammation due to lack of proper cleaning. According to research, such infection can contribute to the development of various disease including cardiovascular and stroke.

It is clear that wisdom tooth has erupted even without causing pain but can later cause a problem due to improper oral hygiene. Wisdom tooth removal at an early age is, therefore, associated with fast and easy recovery.
