Role of Clinician's Experience and Implant Design on Implant Stability. An Ex Vivo Study in Artificial Soft Bones

摘要: Objectives: Clinical experience in implant placement is important order to prevent failures. However, the design affects primary stability (PS) especially poor quality bones. Therefore, aim of this study was compare effect clinician surgical on PS, when placing different type designs. Methods: A total 180 implants (90 parallel walled-P and 90 tapered-T) were placed freshly slaughtered cow ribs. Bone evaluated by two examiners during surgery considered as ‘type IV’ bone. Implants (o 5 mm, length: 15 mm, Osseotite, BIOMET 3i, Palm Beach Gardens, FL, USA) three clinicians (master/I, good/II, non-experienced/III, under direct supervision a manufacturer representative; 30 implants/group). An independent observer assessed accuracy resonance frequency analysis (RFA) with quotient (ISQ) values. Two-way variance (ANOVA) Tukey's post hoc test used detect their interaction effects PS. Results: All mechanically stable. The mean ISQ values were: 49.57(± 18.49) for P-implants 67.07(± 8.79) T-implants. two-way ANOVA showed significant (p < .0001), (p < .0001). multiple comparison differences RFA group I/II (p = .015) highly (p < .0001) between I/III II/III. presented (for I, II, III) 31.25/49.18/68.17 T-implants higher values, 70.15/62.08/68.98, respectively. Clinicians I II did not show extreme (p = .016). In contrast, III achieved high using P- following exact protocol based guidelines. provided experienced compared P-implants. Conclusion: greater PS than P-implants. consistently PS; however,
