implant supported fixed restorations

  1. 1. Prepared by: Byadr idrees supervised by: Taban SH. Ameen Dr.Abdulkarim Almzori
  2. 2. Dental Implant Introduction: Dental implant is a device inserted into the jaw bone to support a dental prostheses which penetrate oral mucosa to replace the natural tooth.
  3. 3.  In 1952 Per-Ingvar Brånemark used a titanium implant chamber to study blood flow in rabbit bone and noted that the chambers could not be removed at the end of the experiment. He called the discovery
  4. 4. • Severe morphologic compromise of denture supporting areas • Poor oral muscular coordination • Low tolerance of mucosal tissues • Parafunctional habits • Active or hyperactive gag reflexes • Psychological inability to wear removable prosthesis • Single tooth loss • Unfavorable number and location of abutments in a residual dentition
  5. 5. Contraindications for Dental Implant 1. Acute illness. 2. Terminal illness. 3. Pregnancy. 4. Uncontrolled metabolic disease. 5. Tumoricidal radiation to the implant site. 6. Unrealistic expectation. 7. Improper motivation. 8. Lake of operator experience. 9. Unable to prosthodotically restore.
  6. 6. 1. Preservation of bone 2. Improved function 3. Aesthetics 4. Stability and support
  7. 7. 1. Can’t be used in medically compromised patients who can’t undergo surgery 2. Longer duration of treatment 3. Need of patient cooperation 4. expensive

  11. 11. Osteo integration is a direct structural and functional connection between living bone • and the surface of load carrying implant ,which mean that there is no progressive motion between the living bone and the implant under functional test for entire life of the patient providing mechanical stability with out distortion at the interface area
  12. 12. 1. Replacement of dentition and supporting tissues to restore function and appearance 2. Alveolar bone preservation.

  14. 14. • The impression materials used in dental implantology should have the following criteria : 1. Accurate 2. Viscosity 3. Stiffness
  15. 15. Type I (Condensation reaction) Type II (Addition reaction) PolysulphidesSiliconesPolyethers
  16. 16. A-abutment level We have two types of abutment: 1-titanium 2- zirconium And screwed to fixture, the abutment is prepared intraorally and the impression is taken like that of the ordinary crown and bridges technique B- implant(fixture level)
  17. 17. there are two impression techniques are used in dental implantology : 1- indirect (close-tray) technique. 2- direct (open-tray) technique. IMPRESSION TECHNIQUES
  18. 18. The analogs are inserted into impression post & secured using the sure-grip screws.
  19. 19. A flexible gingival mask should be fabricated for all implant work. It ensures optimal contouring of the crown. When removed , it allows unhindered view of the neck of the implant fixture.
  20. 20. The stone model with the flexible gingival mask & analogs for the restoration is now complete. The stone with the gingival mask removed.
  21. 21. Surgical procedure
  22. 22. Treatment option
  23. 23. Dental implant-supported prosthesis (single crown, fixed bridge, full arch implant)
  24. 24. Dental Implants treatment option 1-Replacing a Single Missing Tooth • A crown is used to replace one missing tooth – each crown attaches to its own implant.
  25. 25. 2-implant supported crown1- tooth supported bridge
  26. 26. This method of tooth replacement can be very esthetic and functional for a period of time. But?? 1- tooth supported bridge
  27. 27. advantages to replacing a single missing tooth with an implant-supported crown: 1. It looks, feels, and functions like a natural tooth 2. It is much more esthetic long term 3. It does not decay 4. There is no need to grind down the adjacent natural teeth 5. The bone is preserved, preventing a visible bony defect 6. It is more hygienic than a tooth-supported bridge
  28. 28. 2-Replacing Multiple Missing Teeth
  29. 29. there are three common treatment options: 1-the traditional tooth supported bridge, 2-a removable partial denture and 3-an implant supported bridge. In this situation the benefits of implant-supported teeth are even more obvious because comfort and stability are also concerns.
  30. 30. The advantages of replacing multiple missing teeth with implant-supported bridges include the following: 1. They look, feel, and function like natural teeth 2. They are much more comfortable and stable than partial dentures 3. Natural biting and chewing capacity is restored 4. They virtually stop the bone resorption (deterioration) process 5. The integrity of the facial structures is maintained 6. Adjacent natural teeth are not compromised by grinding them down into peg shapes or slowing loosening them with pressure
  31. 31. 3-full arch Replacement
  32. 32. Some of the many advantages of implant supported replacement teeth include the following: 1. They are more comfortable and stable than traditional dentures 2. They virtually stop the bone resorption (deterioration) process 3. Integrity of the facial structures is maintained 4. Appearance is improved 5. It is not necessary to cover the roof of the mouth, so food can be tasted 6. Relines and repairs are infrequent compared to traditional dentures 7. Natural biting and chewing capacity is restored
  33. 33. Free-End Distal Extension ( 1 ) a single implant placed distal to the most posterior natural abutment and (2) A fixed prosthesis made to connect the implant and a natural tooth abutment. The implant dentist has two options in treating the patient missing terminal posterior abutments:
  34. 34. Esthetic Zone • Anterior region The implant must have 1- proper position, 2- angulation, 3-and depth for esthetic restoration SPECIAL SITUATIONS:-
  35. 35. Posterior region problems….. 1 - Presence of the inferior alveolar nerve limits implant length. 2 -increased occlusal load is one reason for the higher implant failure rate in this region
  36. 36. Overview of Steps in Replacing Missing Teeth with Dental Implants: i. Examination and preliminary X-rays and/or C.T. scan ii. Extraction of tooth/teeth as needed iii. Soft tissue grafts and/or bone grafts as needed iv. Placement of the dental implants v. Delivery and installation of the prosthesis: crown, fixed bridge, or removable prosthesis
