RESUMEN
Introduction: The invention of dental implants has replaced the fixed partial dentures for the replacement of the teeth. Hence, in the present study, we compared the surface characteristics of various zirconia dental implant systems. Materials and Methods: We conducted an in vitro comparative study of 50 implants of the dental implant systems "Straumann pure ceramic implants (SC) and Bredent dent whiteSKY™ (BW)." Scanning electron microscopy (SEM) was used to compare the groups for the surface characters at the different regions of the implant surface. Results: SC showed deep markings on the surface and droplets, and BW showed smoother surface and bigger droplets under the SEM. Conclusion: SC may perform better in the clinical conditions as the surface characters are better than the BW.
RESUMEN
Introduction: The implants have brought a paradigm shift in the replacement of lost teeth. The complete dentures that are implant fixed have increased acceptance among patients. Since these are recently introduced, we aim to evaluate the prosthetic complications and the survival of the implant-fixed complete dental prostheses. Materials and Methods: We piloted a retrospective study among subjects who received "implant-fixed complete dental prostheses (IPs)." We included 100 subjects with different IPs from the department records who complied with the follow-up. Prosthodontic complications and the survival of the IP were noted and presented as percentages. Results: Of the 100 subjects finalized in our study, 78 had metal acrylic (MA) and 22 metal ceramic (MC). The mean survival of the MC and MA was 5.2 and 5.1 years, respectively. The most common minor and major complications were "loss of screw access hole material, chipping of the veneering material, and chipping events." Parafunctional habits affected the survival of the IP along with the reluctance to wear the night guard. Conclusions: Good survival and only a few prosthetic complications are associated with the IP and showed good patient satisfaction.
