Excerpt from Research Paper :
According to the study, the clinical evidence does not recommend the application of implanto-prosthetic zirconium abutments in a patient's molar region.Nakumura et al. (2010) conducted a systematic review of Zirconium as a dental implant abutment matter. The focus of their study was to assess the already published data on the concept of concerning zirconia dental implant abutments.
The work was focused on the study of the mechanical properties of zirconium abutments, the peri-implant soft tissues that surround zirconia abutments, plaque accumulation on the zirconia as well as the survival of the zirconia abutments.
The selected studies indicated that the that the zirconium abutments were very reliable in the anterior region from both mechanical and biologic perspectives.The studies also concluded that in comparison with titanium, zirconium abutments may be a material surface that is less attractive for phenomenon of early plaque retention.
The study further indicated that 3 clinical follow-up studies showed that zirconium abutments could as well function without any fracture as well as peri-implant lesions. Nakumura et al. (2010) concluded that on the basis of the literature review, zirconium has a great potential of being used as a perfect dental abutment material but there is a need for further studies on certain issues.
Ekfeldt, Furst and Carlsson (2011) conducted a retrospective as well as a clinical follow-up study aimed at evaluating zirconia abutments for use in single-tooth implant restorations. The objective of the study was to evaluate the outcome of clinical trials of custom-designed zirconia abutments for use in implant-supported single-tooth restorations for a period of up to five years after insertion. Retrospective evaluation was the first pert of the study and it involved the evaluation of a total of one hundred and thirty patients who were treated with one hundred and eighty-five single tooth implant restorations by means of zirconia abutments. The second part of the study involved the clinical examination of a total of twenty five patients who had forty restorations that were placed more than three years ago. The implants were placed by oral surgeons and the prosthodontic treatments were duly provided at clinics that were being ran by prosthodontic specialist. The restoration process was either a screw-retained single piece restoration or all-ceramic crown for the cementation. The results indicated that in for both cases, the zirconium abutments had a good performance in the follow-up period. The biological and technical complication rates were low and most patients were generally satisfied with the process of restoration. The paper concluded that Zirconium abutments for use in single-patient crowns appeared to demonstrate an acceptable level of biological and technical results.
