| Aim of the study: To evaluate and compare the influence of the conventional solid-structure (CSS) implants versus the direct metal laser sintering (DMLS) implants regarding primary and secondary stability. Materials and methods: A total of 12 implants of two different designs were tested , six partially edentulous male patients having full set of teeth upper arch opposed by Kennedy class I lower arch with second premolar as last standing abutment bilaterally received twelve implants at the second molar area bilaterally, each patient received two implants of the same size, diameter and implant abutment connection, one conventional solid-structure (CSS) implants (control group) at the right side and one direct metal laser sintering (DMLS) implant (test group) at the left side. Primary and secondary implant stability were measured and compared by resonance frequency analysis using osstell device at time of implant insertion, weeks 1, 4, and 12 after implant insertion. Result: there was a statistically insignificant difference in stability values between direct metal laser sintering (DMLS) implants (test group) and conventional solid-structure (CSS) implants (control group) throughout the follow up periods except at 12 weeks follow up period there was a statistically significant increase in stability values in direct metal laser sintering (DMLS) implant (test group) compared to the conventional solid-structure (CSS) implants (control group). Conclusion: Direct metal laser sintering (DMLS) implants showed higher secondary stability values than conventional solid-structure (CSS) implants. | ||
