Presentation Transcript

  1. 人工植牙 高醫牙科 吳逸民

  2. Osseointegration: direct bone-to-implant interface

  3. 兩階段植牙手術 2 staged implant surgery

  4. 第一階段 牙根植入 Implant installation

  5. L L B B

  6. 6 months 上顎 經過 ........... 以後 3 months 下顎

  7. 第二階段 Abutment connection 橋基接著 及 假牙製作 Implant prosthesis

  8. L L B B

  9. 親和性 骨整合 Cell friendly Osseointegration

  10. 骨整合 • The Standard Goal of Implant Healing: Osseointegration

  11. Osseointegration Failed Implant Failing Implant

  12. Osseointegration Fully Osseointegration Failed Osseointegration

  13. 穩定度 Stability

  14. 穩定度Primary And Secondary Stability

  15. Primary Stability: • Created At The Time of Implant Placement • By Press-Fit • Mechanical Stability

  16. Primary Stability: • Implant Length And Shape • Bone Quality And Quantity • Implant Bed Preparation Technique

  17. Primary Stability: • The Amount Decreased Proportionally With The Time

  18. Secondary Stability: • Created By Deposition of New Bone • Remodeling of Bone • Biological Stability

  19. Secondary Stability: • Increased Gradually During Healing Process

  20. Implant Stability

  21. Implant Stability • Total Stability: • The Sum of Primary Stability And Secondary Stability

  22. Implant Stability • Stability Dip: • Transition Period Between Primary And Secondary Stability In The Bone Formation Process • Most Implant Failure Occur In The Critical Early Period Between Week 2 And 4 • “Pivotal Dip”

  23. Elimination of Stability Dip Moved The Stability Dip Curve Upward By Increased Implant Stability

  24. Elimination of Stability Dip Shift The Curve To Left By Increasing Primary Stability

  25. 植體形狀Straight Implant

  26. Taper Implant

  27. Rough surface

  28. Progressive thread

  29. Elimination of Stability Dip Shift The Curve To Left By Reducing Implant Healing Time

  30. Elimination of Stability Dip • Speed Up The Process of Osseointegration • Improve The Bone-to-Implant Contact (BIC) • Improve Removal Torque Values (RTV) 促進骨生長

  31. Elimination of Stability Dip TPS : 8 To 12 Weeks SLA : 6 To 8 Weeks

  32. Conclusion of Implants Healing • Achieving Faster Osseointegration • Shorter Healing Periods Prior To Restoration

  33. 植體表面 粗糙面   促進 骨/植體 接合  親水特性  促進 骨癒合

  34. Macro-roughness

  35. 最簡單、最能預期的治療就是最好、最成功的治療方法最簡單、最能預期的治療就是最好、最成功的治療方法

  36. 順應時代潮流 – 植牙 傳統 跟不上時代 ! 固定牙橋 ? 不夠炫 ! 不夠科技 ! 活動假牙 ? 落伍啦 !

  37. Who Are Candidates For Implant Therapy?

  38. Patient selection

  39. 穩定活動假牙

  40. 取代活動假牙

  41. 不想破壞鄰牙
