Abutments design & selection /orthodontics training courses

  1. 1. Abutment design and selection www.indiandentalacademy.com
  2. 2. After completing second stage surgery and removing the healing collars, start the final restoration. In order to affix a final prosthesis to the implant fixture, abutments must be used as intermediate devices. It is the component which extend through the gingival tissue overlying the implant. www.indiandentalacademy.com
  3. 3. Implant position and angulation may require different abutments to allow optimum esthetics. www.indiandentalacademy.com
  4. 4. ONE PIECE ABUTMENT TWO PIECE ABUTMENT Central screw & outer housing Fits over external hex of implant Abutments may consist of one, two or three constituents which may be separate or unified www.indiandentalacademy.com
  5. 5. Collar with hexagonal base Angled abutment 15,20,25degree Fixation screw www.indiandentalacademy.com
  6. 6. Abutment selection Visual inspection after abutment surgery may give an indication of appropriate abutment selection, www.indiandentalacademy.com
  7. 7. But the proper abutment can only be selected by diagnostic procedures including trial setups or provisional restorations on a diagnostic cast with abutments incorporated in the trial restoration. . Aluminium abutment analogs are available for use in diagnostic procedures to select the proper abutments.www.indiandentalacademy.com
  8. 8. Abutment Analogs www.indiandentalacademy.com
  9. 9. The implant abutment interface must interlock to prevent rotation. The abutment screw must withstand high enough torquing forces to prevent it from becoming loose, yet the force must not be so strong that it will fracture the abutment screw . www.indiandentalacademy.com
  10. 10. Anti rotational features of implant systems Anti rotational features on implant inhibit unwanted movement of their overlying abutments. Anti rotational components in current use include External hex, Internal hex, Spline type interface, Morse taper www.indiandentalacademy.com
  11. 11. External hex Is the most widely available. It offers a great variety of restorative options due to interchangeability of abutments among manufacturers. Abutment must engage the external hex on top of implant. www.indiandentalacademy.com
  12. 12. internal hex It provides more precise implant to abutment interface and allows easier intra oral abutment connection. There is less abutment movement once it is seated and fastened.(Paragon and Frialit). www.indiandentalacademy.com
  13. 13. The spline attachment Are fin to groove anti rotational configurations. Each of the 6 external components which are called tines protrude 1 mm from implant and are matched to a female embedded in the abutment base. (Calcitek) www.indiandentalacademy.com
  14. 14. Morse taper design Angled abutments-15&25degree inclinations. (Bicon) www.indiandentalacademy.com
  15. 15. Abutments can be obtained from manufacture in machined form or can be custom-cast by a laboratory using manufactured gold or plastic components. www.indiandentalacademy.com
  16. 16. www.indiandentalacademy.com
  17. 17. • A preformed plastic pattern is fitted to the abutment in the laboratory www.indiandentalacademy.com
  18. 18. Inlay casting wax is added and entire crown is formed. www.indiandentalacademy.com
  19. 19. • The wax is then cut back so that the correct bulk will be given to the areas in which porcelain is to be added. www.indiandentalacademy.com
  20. 20. The backing is invested and cast in a gold – content gold palladium alloy www.indiandentalacademy.com
  21. 21. After cleaning and polishing an opaque layer is fired onto the backing & Build up the remainder of the neck, body and incisal edge of the crown. www.indiandentalacademy.com
  22. 22. www.indiandentalacademy.com
  23. 23. Infinite position implants are available with a high noblemetal base Suitable for a variety of implants, to which a plastic head is fitted at any direction . After determining the desired position & angulation,it may be cast in gold to the base. These abutments are screw retained. (0 to 20 degrees) www.indiandentalacademy.com
  24. 24. Implant abutment preparation kit Designed to give the clinician the proper tools to correctly prepare titanium stock implant abutments, or modify custom cast implant posts to achieve proper fit and emergence profile to optimize implant prosthetics. www.indiandentalacademy.com
  25. 25. • 1.   Attach the stock titanium post securely to  the appropriate implant analog.  • 2. Then place the analog / post combination  into the optional abutment holder.  The  insulated abutment holder allows the clinician  to secure the abutment for proper preparation,  protecting the fingers from the heat generated  during the process. www.indiandentalacademy.com
  26. 26. • 3. Using the Gross Reduction heatless  stone, occlusal and proximal  surfaces  can be modified. •  .   www.indiandentalacademy.com
  27. 27. • 4.   Once the desired gross reduction has been achieved, use the fine tuning burs to refine the margins to the proper contours. • 5.   The marginal configuration should resemble that of the naturally prepared tooth.   www.indiandentalacademy.com
  28. 28. • 6.   The Abutment Preparation Kit comes with FOUR fine tuning burs.  www.indiandentalacademy.com
  29. 29. • STRAIGHT PREPARATION BUR • There is also a long chamfer bur. www.indiandentalacademy.com
  30. 30. • TITANIUM CUTTING CHAMFER (SHORT) www.indiandentalacademy.com
  31. 31. • TITANIUM CUTING CHAMFER (LONG) www.indiandentalacademy.com
  32. 32. • 8.  The Abutment Preparation Kit comes with THREE polishing wheels. Use these polishing wheels to smooth out any rough spots.  Use from coarse to fine to achieve the best results.  www.indiandentalacademy.com
  33. 33. • BLUE (Coarse)  POLISHING WHEEL www.indiandentalacademy.com
  34. 34. • GREEN (Medium) POLISHING WHEEL www.indiandentalacademy.com
  35. 35. • RED (Fine) POLISHING WHEEL www.indiandentalacademy.com
