| Abstract | ||||
| Objective: The aim of the present study was to evaluate the primary stability of immediate, custom made zirconium root analogue implant. Our 2ry outcome was to evaluate Marginal bone changes at the day of implantation, & after 3 months. Patients and methods: This study included 8 immediate implant placements in fresh sockets in esthetic zones using custom made zirconium implants. A Pre-operative CBCT was obtained for each patient to get the measurements & dimensions of the un-restorable teeth. Patients were prepped for the procedure under LA. Extraction of teeth was done atraumatically. The extracted remaining roots were disinfected then mounted on the laser scanner to produce an stl.file of the remaining roots. Then using the CAD software to modify the root analogue by adding macro retentive “blebs” on the lateral surfaces of custom made zirconium implant. Transferring the design to the milling machine using zirconium blocks. The implants were subjected to surface treatment using sand blasting method, & then sterilized. Patients were recalled after 3 days for insertion; and implantation using tapping technique, to achieve primary stability. The primary stability was measured using periotestM device as a primary outcome. Standardized paralleling technique was used to assure the seating of the implant inside the socket after insertion, & for evaluation of the marginal bone changes as a 2ry outcome. Results: All custom made zirconium implants failed to osseointegrate Conclusion:Within the limitations of this study, the authors could not measure the stability nor the marginal bone changes of custom made zirconium implants | ||||
