Implants

What are implants?

A dental implant is an artificial tooth root that is placed into your jaw to hold a replacement tooth or bridge. Dental implants may be an option for people who have lost a tooth or teeth due to periodontal disease, an injury, or some other reason.

TYPES OF DENTAL IMPLANTS

  • Endosteal (in the bone): This is the most commonly used type of implant. The various types include screws, cylinders or blades surgically placed into the jawbone. Each implant holds one or more prosthetic teeth. This type of implant is generally used as an alternative for patients with bridges or removable dentures.
  • Subperiosteal (on the bone): These are placed on top of the jaw with the metal framework’s posts protruding through the gum to hold the prosthesis. These types of implants are used for patients who are unable to wear conventional dentures and who have minimal bone height.

    Advantages and Disadvantages of Dental Implant

    ADVANTAGES

    »
    Dental implants reduce the load on the remaining oral structures/teeth by offering independent support and retention to crowns, bridgework and overdentures.
    » Dental implants preserve natural tooth tissue by avoiding the need to cut down adjacent teeth for conventional bridgework.
    » Dental implants will preserve bone and significantly reduce bone resorption and deterioration that results in loss of jawbone height.
    » Dental implants have been shown to reduce the need for subsequent restorative intervention of adjacent teeth.
    » Long-term data on implants suggest that implants last for a much longer time than conventional restorations on teeth.
    » Loose fitting dentures can be replaced with improved support, stability and retention with implant overdentures.
    » Overdentures will help control/improve facial contours that result in minimizing premature wrinkles.
    » Implant overdentures may allow you to chew your food better and speak more clearly. Many studies have shown that overdentures contribute to improved chewing efficiency and speaking, compared to full dentures.

    DISADVANTAGES

    » A surgical procedure for implant placement and a period of healing is necessary before the prosthesis may be completed.
    » Dental implant procedures may entail an increase in cost compared to conventional dentistry.
    » Mechanical fracture of fixtures, bridges, bridge attaching screws or abutment screws and loosening of screws can occur. Reported occurrences are less than 5% of patients. Trauma to the mouth or jaws or stress concentration from the bridge could result in mechanical failure and complications.
    » Porcelain fracture of crowns and bridgework on implants is much more prevalent than on natural teeth due to a lack of shock-absorbency between the implants and the bone.
