Everything you want to know about All-on-4 dental implants

All-on-4 implants are placed on the upper and lower jaw of your mouth. These are prosthetics that act as a replacement for a full row of teeth just using four dental implants. The implants are made of titanium and are screwed into the upper and lower jaw.

Implants restore the function of the teeth. It is a modern and convenient method of replacing lost teeth. A patient could lose teeth due to various reasons like, an injury, an unfortunate accident or a simple case of tooth decay. Whatever the cause, all-on-4 can help replace even the most severe tooth tosses.

Many people prefer all-on-4s over dentures. There are many reasons for that – for example the adhesive used in dentures can loosen prematurely, dentures force the wearer to avoid certain foods, dentures affect speech, etc. There is also one more major drawback to dental dentures. Dentures decrease the bone density of the jaw. It is due to the absence of teeth which have been removed. When dentures are fitted into the teeth, the jaw slowly loses its bone density.

Whereas, with all-on-4 implants, it has a very secure attachment to the jaw because the implants are directly embedded into the jawbone. They provide the same structure as teeth and keeps stimulating the jawbone, in turn giving it strength. Implants provide stability to the jaw bone just like real teeth. This means the patient does not have to stop eating any type of food or consume any special diet.

Benefits of All-on-4 implants

Let’s start with the benefits of using All-on-4 implants. As compared to other dental implants, these implants have the following benefits:

  • It is safe
  • It is convenient and the procedure is short
  • Easy to maintain
  • No need to alter diet
  • No pain experienced between teeth and gums
  • Shorter healing time

The implant procedure

Before heading into treatment, it helps to know exactly what goes on during the procedure. The procedure is performed under local anaesthesia or sedation. The teeth are scanned to determine the placement of the implants. The dentist then removes any damaged teeth and rotten/affected tissue. Next, an incision is made in the gums to expose the jaw bone. A small hole is drilled and the implant is screwed in.

For the implants, posts are set in such a way that stability of teeth is increased and tension is reduced while biting and chewing. The posts are then connected to the abutments, which connect the denture plates to the implants.

Once all the implants are completely fitted, denture plates have to be fitted. After the plates are fitted nicely, there is no need to remove it again as it will act like the natural teeth.

The patient may be called one last time, to replace the temporary prosthesis and replaced by permanent ones. For this, impressions are taken of the fully healed gums. Then according to the impressions, a permanent prosthesis is crafted and then fit into the mouth. After this, the procedure officially ends.

How it works

These implants are carefully placed in four places inside the mouth on the upper and lower jaw. The purpose of these implants is to support the fixed dentures and eliminates the need to get an implant for each and every tooth. The implants are made of titanium material and easily mix with the jawbone. Tooth implants feel just like natural teeth. They also function just like natural teeth. They can also chew normally and have a natural appearance.

Suitable candidates

This treatment is not suitable for people suffering from serious health conditions as this can have a serious impact on the health of the patient. Patients with autoimmune diseases like diabetes, lupus, etc. or are immunocompromised, they cannot receive this treatment. A shaky immune system will not help the implants heal quickly. This will only hurt the patient further.

The implants will infuse with jawbone in the same time. Patients will be given proper advice to look after and care for their teeth. Pain relievers will also be provided. You may also be advised to visit the dentist a few more times just to make sure that the implants are working just fine. For the following few months, the patient may be advised to eat soft foods but it is not necessary.

The implants are maintained easily. To heal faster and to maintain them properly, gargle and rinse your mouth with salt water. After doing this, you just have to look after your implants just the same way you would look after your natural teeth. Brush them twice a day and floss once.
