Implant Scanoguide technique

  1. 1. Laboratory Fabrication of Implant Scanoguides Gold Standard for Implant Placement
  2. 2. Presented by
  3. 3. effectdental@comcast.net 219-310-8296
  4. 4. A new service to offer for Removable Laboratories • Fixed laboratories hate to work with acrylic. • Dentists hate to work with acrylic. • Dental assistants hate to work with acrylic. • Removable technicians love acrylic.
  5. 5. Planning Tool for implant placement
  6. 6. Single Gradient using clear acrylic
  7. 7. Dual Gradient style for placing implants used for bar retained denture.
  8. 8. Single or Multiple Tooth Guides
  9. 9. Single or Multiple Tooth Guides
  10. 10. CT Scanning
  11. 11. Radiographic Stents used with CT Scan discern angle of placement in relation to restoration to bone.
  12. 12. Aids in selection of fixture style based on bone shape, bone availabilty and restoration position placement.
  13. 13. Provides Closer approximation to placement of implant fixture at bone height.
  14. 14. Evaluate Bone Quality
  15. 15. Radiographic Stent/ Guide Fabrication
  16. 16. Positioning
  17. 17. Approximate restoration position
  18. 18. Emergence Profile • Waxed in ridge contact. • Follow contour of emergence.
  19. 19. Duplication • If using hydrocolloid, wax tooth positions in sticky wax or hard wax to avoid change in position. • Duplication silicone works better.
  20. 20. Duplication complete
  21. 21. Pontic fabrication using laboratory putty
  22. 22. PVS Putty
  23. 23. Injection Holes
  24. 24. Injection Holes
  25. 25. Mix 30% Scanocryl with self cure monomer.
  26. 26. Load monoject syringe with Scanocryl
  27. 27. Inject Scanocryl into mold while on model until scanocryl extrudes from adjacent hole
  28. 28. Cure on model using convention self cure method.
  29. 29. • Trim and fit to ridge to evaluate the placement. • Pontics should fit on ridge and rest in place.
  30. 30. Create occlusal /incisal retention • Thin out duplicate model to allow for good vacuum forming. • Pro-form .120 or .100 splint material. (P.E.Thalate) acrylic needs to stick to it.
  31. 31. Trim index and check fit
  32. 32. Affix • Affix pontics to index with either light cure clear, cyanoacrylate, or some clear self cure. Do not use Scanocryl or any radiopaque product.
  33. 33. Duplicate approved diagnostic arrangement in PVS lab putty
  34. 34. • For dual gradiant guides • For single gradiant fill tooth intaglios with guides fill tooth 30% Scanocryl and fill intaglios with 30% the base with 10% Scanocryl and base with clear self curing acrylic.
  35. 35. Dual Single
  36. 36. Want More? Besides fabrication for dental practices, Matrix Dental Laboratory offers education for groups, associations, departments, and individual labs. 219-310-8296 630-531-8197 matrixdental@comcast.net www.matrixdentallab.com
