1) WHAT ARE DENTAL IMPLANTS?

A natural tooth consists of a crown (the part you see above the gum), and a root (the part hidden under the gum). It is the root in the jawbone that actually holds the natural tooth in place.

A dental implant is a small man-made titanium fixture that serves as a replacement for the root portion of a missing natural tooth. Titanium is used because it is the most compatible with our human body.

After the bone has grown around the implant, implants can hold a crown, bridge or over-dentures just like roots that hold natural teeth in place.

2) WHY IMPLANTS?

When natural teeth are removed, many complications will result.

• The remaining teeth shift, rotate and become crooked.

• An improper bite will develop, making it very difficult to chew food properly

• Spaces and gaps between teeth may cause embarrassment, problems with speech, and lack of self confidence

• The bone that previously supported those teeth melts away, or deteriorates, which in case of complete tooth loss results in collapsed facial profiles, lost lip support, increased wrinkles around the mouth and the appearance of a pointed nose and chin that are too close together.

Dental implants, when properly placed, can restore missing teeth, thereby eliminating these potential complications. 

 

3) IMPLANTS ADVANTAGES

• Implants look, feel and function like a natural tooth.

• Implants do not decay under their crowns, bridges or removable dentures.

• Implants are more hygienic (easier to clean).

• Implants are much more comfortable and stable, increasing the sense of security that teeth will not fall out when eating, laughing or sneezing.

• Implants stop the bone shrinkage process (Resorption), preventing a visible bony defect, maintaining the integrity of the facial structure and improving the appearance.

• Adjacent natural teeth are not endangered (neither ground down nor loosened).

• It is not necessary to cover the roof of the mouth, thus improving the ability to taste foods.

• Relines and repairs are infrequent compared to traditional dentures.

• Denture adhesives are completely eliminated.
   

4) IMPLANTS INDICATIONS

• To restore missing teeth.

• To immobilize loose teeth.

• To stabilize dentures that slip or cause sore spots when chewing or those need to be relined frequently because of bone resorption.

• Substitute existing bad crowns or bridges, either functionally or cosmetically.
   

5) IMPLANTS CONTRAINDICATIONS

General Contraindications

• Alcoholism, drug abuse or hypersensitivity to Titanium (rare)

• During pregnancy and breast feeding

• Children until bone maturity

• Diseases as:

  • Immunodeficiency (AIDS).

  • Uncontrolled Diabetes (insulin-dependent).

  • Cancers and radiotherapy (Face and/or Neck).

  • Hyperthyroidism and other endocrinal disorders.

  • Cardiovascular, blood, bone and Neurological disorders.

  • Coronary insufficiency (Angina pectoris and myocardial infarctions within the last 12 months).

Local Contraindications

• Oral infections.

• Poor oral hygiene.

• Insufficient bone volume.

• Tumors (benign or malignant) around the implant site.

• Uncontrolled Para functional habits as Bruxing, Clenching and Gnawing.
   

6) IMPLANTATION STEPS

Medical Examination

Before any implant treatment the patient’s general health must be clearly established
using medical history and full blood analysis to assure no General contraindication.

Dental Examination

This usually involves x-rays, clinical examination and may include taking impressions formodels of your teeth to assure no Local contraindications.

Procedures

• The implant is placed in the bone using a gentle surgical techniqueand local anesthesia. Each implant takes from half an hour to one hour.

• The implant is left undisturbed for a period of 2-6 months so that
  bone can form a strong biological bond to it.

• During this bone “remodeling” phase, you may have some type oftemporary replacement tooth, so that you never have to be without teeth during treatment.

• After the bone remodeling period, a small post called an abutment is attached to the implant.

• Impressions are made for your teeth and the implant abutments,appropriate color for your replacement teeth is confirmed and replacement teeth are then placed and cemented to the abutment.
   

7) PRECAUTIONS AND MEDICATIONS FOLLOWING IMPLANT SURGERY.

Precautions and medication following implant surgery

 

Bone Grafting

Sometimes, it is necessary to build up the bone in the area of implants to insure success. This is called Bone Grafting, which is a very common procedure in dentistry. In such a procedure we need a source of bone.

• The best bone is the bone taken from the patient. This bone can be taken from other areas of the mouth or is taken from areas outside the mouth, such as the hip.

• Another very common source of bone is bone taken from cadavers. This bone is harvested under very strict supervision at several bone banks. There has never been a case of a transmitted disease with this type of bone. It is very safe and very useful in our work to help patients.

• A third type of bone is a synthetic type of bone. This has some use in dentistry but it does not seem to be as useful as the first two types of bone.
