The surgical kit for Zirconia implants is shown in Figure 22. All of the components in the surgical kit are made of Zirconia, and the surgical steps are very similar to those for any other permanent titanium overdenture implant. (Fig. 23) The prosthetic steps for using Z-Look 3® Lock Ball are very similar to any other permanent titanium male overdenture implant. We strongly recommended that female caps not be retrofitted into the denture until at least 6 weeks after implant placement. During this period the denture should be relined over the ball attachment with tissue conditioner. Note: There should be absolutely no contact between the denture base and the Zirconia ball attachments. CONCLUSIONS Implant surgeons who desire to work with dentists providing implant supported overdenture therapy must have complete understanding of different attachment assembly designs and their correlation with the number of supporting implants. Additionally, surgeons should understand the biomechanical aspects of this treatment modality as well as the relationship between |
height of available bone and the appropriate attachment assembly. ACKNOWLEDGEMENTS The main source for this manuscript Dr. Hamid Shafie, received his certificate of advanced graduate studies in prosthodontics from Boston University Goldman School of Dental Medicine. He was the co-director of the Center for Oral Implantology at Johns Hopkins University where he trained many dentists in different aspects of implant dentistry. Dr. Shafie currently is the President of the American Institute of Implant Dentistry, a not-for-profit teaching institution, in Washington DC. He is the director of postdoctoral implant training at Washington Hospital Center Department of Oral and Maxillofacial Surgery. In addition, Dr. Shafie is the author of a text book, Clinical and Laboratory Manual of Implant Overdenture, published by Wiley-Blackwell in 2007. He lectures nationally and internationally about innovative aspects of implant dentistry. |
