Dental implant

  1. 1. Vahel Qasim Othman
  2. 2. 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 reasons.
  3. 3. Dental implants have been used since 1970 since that time they have undergone many improvements in design Modern implant come in variety shapes and sizes to suit for different teeth they replace.
  4. 4. Dental implant have three basic parts: The implant "fixture." The fixture is that part of the implant that is embedded in and becomes fused with the jawbone. The implant abutment. The abutment portion of a tooth implant is that part that lies at and above the gum line. It's the part that supports and secures the dental work (crown, bridge, denture) that's placed on it.
  5. 5. The crown. Once the dental implant and the abutment are in place, your dentist fits the crown, the bridge or the prosthesis.
  6. 6. -Endosteal -Subperiosteal -Transosteal
  7. 7. Within the bone)Endosteal Is the most common one ,in this type the gum is opened up then the bone is hole drilled Titanum screw is inserted within the jawbone once the bone is healed the tooth can be screwed in place
  8. 8. On the top of the bone)Subpirosteal Less used, during this implant the screw is placed under the gum on top of bone. This process is used when patient have minimal Bone height and are unable to wear denture
  9. 9. Through the bone)_Transosteal Used less than both previous types, in this method we need to drilling completely through lower jaw then bolting the mental plate in to the bottom of mouthe.The titanium then goes through the bone ,this method also requires opening the skin under the chin ,this method has high failure rate
  10. 10. If you are missing aa SingleToothReplacing single tooth, one implant and a crown can replace it. If you are missingReplacing SeveralTeeth several teeth, implant-supported bridges can replace them. If you are missingReplacing All ofYourTeeth all of your teeth, an implant-supported full bridge or full denture can replace them.
  11. 11. The screw type implant: the most Common used . this can be placed in smaller sockets and transmit biting force efficiently to the bone
  12. 12. The cylinder-form implants: are also a major type of the dental implant These implants have a cylindrical shape without screw threads and can be placed easily in the jawbone.
  13. 13. Hollow implants These implants resemble screw-type implants in their shape. However, they are hollow and the lateral surface has multiple holes. As bone tissue can penetrate into the implant through these holes, the contact area with the bone is increased, and therefore, a high bonding force can be obtained. However, these implants have weak strength characteristics and have a risk of breakage.
  14. 14. Blade implants Blade implants in the form of plates, which had been used before
  15. 15. Improve appearance :it looks like your own teeth and as they fuse in bone they become apartment Improve speech: with poor fitting denture speaking will be more difficult Improve comfort: because they become part of you it reduce discomfort ably of removable denture Improve eating: sliding denture make chewing difficult
  16. 16. Strong and stable Protect bone : stimulate bone growth and prevent bone lose No cavity
  17. 17. More expensive than other alternatives Time consuming as it need surgery It may cause gum diseases
