Influence of Abutment Screw-Tightening Methods on the Screw Joint : Immediate and Long-Term Stability
Copyright © 2024 Manlin Sun et al..
Objective: To evaluate the influence of screw-tightening methods on the immediate and long-term stability of dental implant screw joints. Methodology. A total of 150 implants of three different implant systems with different diameters were used in this study. Each group was divided into three subgroups (n = 5), according to the tightening methods (A-tightening with recommended torque and retorque after 10 min; B-tightening with recommended torque, then loosening and immediate retorque; C-tightening with recommended torque only once). The operating time of tightening the assemblies was recorded. Ten minutes later, the immediate removal torque (IRT) (Ncm) was measured. After retightening the assemblies, a dynamic load between 20 and 200 N was applied for 105 cycles, and the postloading removal torque (PRT) (Ncm) was measured. Scanning electron microscopy (SEM) was used to observe the surface topography of the screws.
Results: For different types of implants, the IRTs were 11.92 ± 1.04-34.12 ± 0.36 Ncm for method A, 11.64 ± 0.57-33.96 ± 0.29 Ncm for method B, and 10.30 ± 0.41-31.62 ± 0.52 Ncm for method C, and the IRTs of methods A and B were 6.28%-21.58% higher than that of method C (P ≤ 0.046). The PRTs were 4.08 ± 0.77-29.86 ± 0.65 Ncm for method A, 4.04 ± 0.40-29.60 ± 0.36 Ncm for method B, and 2.98 ± 0.26-26.38 ± 0.59 Ncm for method C, and the PRTs of methods A and B were 11.77%-44.87% higher than that of method C (P ≤ 0.016). The removal torque loss rates of methods A (12.49% ± 0.99%-65.88% ± 4.83%) and B (12.84% ± 0.96%-65.35% ± 1.95%) were 3.04%-7.74% lower than that of method C (16.58% ± 0.56%-71.10% ± 1.58%) (P ≤ 0.017). The operating time of method A was much longer than those of methods B and C (P < 0.001). The structural integrity disruption of the screw thread was observed according to the SEM results in all postloading groups.
Conclusions: Method B (torquing and then loosening and immediate retorquing) increases the screw joint immediate stability by 6.28%-21.58% and the long-term stability by 11.77%-44.87% compared with method C (torquing only once), has comparable screw joint stability compared with method A (retorquing after 10 min), saves time and is recommended in clinical settings.
