Abstract
Purpose: To evaluate the effect of zirconia and titanium as abutment materials onperi-implant bone height changes and pocket depth in mandibular implant supportedover-denture. Subjects and methods: Ten completely edentulous patients wereselected from the Outpatient Clinic of the Faculty of Dental Medicine for Girls,Al-Azhar University. Two implants were implanted in the inter-foraminal area ofmandibular ridge. Two different abutments were screwed over implants. Right abutmentwas constructed of zirconia and left one was constructed of titanium. Construction ofmaxillary complete denture and mandibular implant supported over-denture for allpatients was performed. Radiographic and clinical evaluation of implants has beenperformed at denture insertion, 6 months, 9 months and 12 months. Results: Theprevious study illustrated that titanium abutments had significantly higher values ofbone height changes and pocket depth measurements than zirconia abutments duringfollow up period. Conclusion: Zirconia abutments had great superiority over titaniumabutments in preservation of peri-implant hard and soft tissues in mandibularimplant-supported over-denture within the follow up period of this study.
