All About Sinus Lift - What is a Sinus Lift?

A sinus-lift is a surgical procedure, performed by trained dentist or dental specialist, to enhance bone mass in the top jaw (maxilla), which increases the chances of successful placement of dental implants. Bone from another part of the body, such as the iliac crest, or artificial bone grafting material is grafted into the bone (endosseous) below the floor of the maxillary sinus. In the upper jaw the amount of bone is condensed by the existence of the sinus. It is also known as sinus augmentation.

A sinus lift is needed 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.

Many people who have lost teeth in their upper jaw predominantly the back teeth, or molars and do not have sufficient bone for implants to be placed. This is mainly due to the anatomy of the skull; the back of the upper jaw has less bone than the lower jaw. In many people bone may have been missing because of periodontal or gum disease.

Many a times tooth loss leads to a bone loss as well. Once teeth are gone, bone begins to be reabsorbed, that is the bone is absorbed back into the body. After the teeth have been missing for a long time, there is not enough bone left to place implants.

Another reason why people go in for sinus lift is that the maxillary sinus may be too close to the upper jaw for implants to be placed. The shape and the size of this sinus vary among persons. Besides, the sinus can get larger as you age.

The bone used for the lift can come from ones own body. The doctors remove bone from your hip or tibia to use for the sinus lift.

There are a number of ways to augment the bone height: such as On lay grafts, Interpositional (Lefort I) grafts, Inlay grafts for nasal floor, Sinus-lift and grafting.

Sinus Infection Medication

A sinus is a cavity in the bones near the nose. The function of these sinuses is to evacuate mucus and air from the nasal membrane. An inflammation of the sinuses leads to trapping of this mucus and dry air inside the sinuses. This causes excruciating pain. Sinus infection medication provides a relief from this pain.

The sinus infections are classified into three categories on the basis of the duration of the illness. Acute sinus infection lasts for approximately three weeks. Chronic sinus infection is the one that lasts from anywhere between three to eight weeks. Recurring sinus infections are the ones occurring frequently over time.

The sinus infection medication depends on the category or type of infection. Acute sinus infections can be cured with home remedies whereas chronic infections demand a prolonged treatment as the symptoms last for a longer duration of time.

The home remedies for treating sinus infection, though do not cure the disease, but are effective in relieving the pain. Inhaling the steam from a vaporizer is perhaps one of the best home medication for sinus infections. Placing a hot cloth over the inflamed area of the face also provides relief.

In addition to these, intake of jalapeño peppers and ripe grapes' juice is also effective. Relief can also be obtained by applying a paste of cinnamon with water, or ginger with milk or water. The steam of eucalyptus oil, hen inhaled, proves an effective treatment for sinus infection. Intake of warm fluids should be increased to allow the trappings in sinuses to open.

Sinus infection medication is prescribed on the basis of the root cause of the infection. At times, diseases like asthma, HIV, cystic fibrosis and certain allergies cause sinusitis. In these cases, before treating the sinusitis, these ailments need to be treated.

Other treatments for sinus infection include decongestants, nasal sprays, antibiotics and pain killers. Because of the side effects, steroids are not prescribed. If the infection is not cured by any of the above mentioned treatments, an endoscopic surgery is resorted to for widening the openings of sinuses.
