“…The interaction between the implant and the adjacent bone immediately after its insertion depends mainly on the macrogeometry of the implant and the topography of its surface [41,42]. However, some studies in the literature still question the influence of surface treatment on the primary stability [12,[43][44][45][46] corroborated the results obtained in the present study, where the two implant designs did not present a statistical difference in the insertion torque values between the treated and non-treated surfaces.…”

The purpose of the present study was to measure and compare the insertion torque, removal torque, and the implant stability quotient by resonance frequency analysis in different polyurethane block densities of two implant macrogeometries. Four different polyurethane synthetic bone blocks were used with three cortical thickness: Bone 1 with a cortical thickness of 1 mm, Bone 2 with a cortical thickness of 2 mm, Bone 3 with a cortical thickness of 3 mm, and Bone 4, which was totally cortical. Four groups were created in accordance with the implant macrogeometry (n = 10 per group) and surface treatment: G1-regular implant design without surface treatment; G2-regular implant design with surface treatment; G3-new implant design without surface treatment; G4-new implant design with surface treatment. All implants used were 4 mm in diameter and 10 mm in length and manufactured in commercially pure titanium (grade IV) by Implacil De Bortoli (São Paulo, Brazil). The implants were installed using a computed torque machine, and following installation of the implant, the stability quotient (implant stability quotient, ISQ) values were measured in two directions using Osstell devices. The data were analyzed by considering the 5% level of significance. All implant groups showed similar mean ISQ values without statistical differences (p > 0.05), for the same synthetic bone block: for Bone 1, the value was 57.7 ± 3.0; for Bone 2, it was 58.6 ± 2.2; for Bone 3, it was 60.6 ± 2.3; and for Bone 4, it was 68.5 ± 2.8. However, the insertion torque showed similar higher values for the regular macrogeometry (G1 and G2 groups) in comparison with the new implant macrogeometry (G3 and G4 groups). The analysis of the results found that primary stability does not simply depend on the insertion torque but also on the bone quality. In comparison with the regular implant macrogeometry, the new implant macrogeometry decreased the insertion torque without affecting the implant stability quotient values.

“…Therefore, Lages et al . concluded, in their systematic review on the relationship between insertion torque (IT) and RFA, that it is important for clinicians to define only one method of evaluation for each implant. Moreover, RFA offers the possibility to measure secondary stability.…”

This study aimed to evaluate the effect of implant size and bone condition on primary stability of orthodontic mini‐implants with a view to predict the primary stability before insertion. Four‐hundred and forty mini‐implants of two different diameters (2.0 and 2.3 mm) and lengths (7 and 12 mm) were inserted at 11 different positions in human cadaver maxillae. Before placement of mini‐implants, cone beam computed tomography (CBCT) scans were performed to measure bone density and cortical thickness and, after mini‐implant placement, implant stability quotient (ISQ) values were determined by resonance frequency analysis and cofactors were analyzed to determine their influence on the primary stability. Additionally, an equation was developed to predict the expected stability based on implant size and bone quality. Bone density varied between 433 (SD 122) and 587 (SD 249) Hounsfield units (HU), and cortical thickness varied between 0.49 (SD 0.42) and 0.98 (SD 0.60) mm. The lowest ISQ value, of 15.50 (SD 7.29) (bone density: 531 (SD 219) HU; cortical thickness: 0.65 (SD 0.58) mm), was found for a mini‐implant of 2.0 × 7 mm and the highest ISQ value, of 46.30 (SD 8.69) (bone density: 587 (SD 249) HU; cortical thickness: 0.98 (SD 0.60) mm), was found for a mini‐implant of 2.3 × 11 mm. Statistically significant influences of the cofactors on primary stability were demonstrated. To visualize the predictive power of the model, the observed values versus the predicted values of primary stability were compared and the model fit was represented by residual plots. The expected primary stability can be estimated by a linear regression model comprising the radiologically determined bone density, cortical thickness, implant length and diameter, and placement position.

“…On the other hand, in the field of dental implantation, the Leckholm and Zerb classification and the Misch classification have been gold standards to clinically evaluate bone quality, and their values are known to correlate with the success rate of implant insertion .

“…26,27 Recently, several objective evaluations, namely, resonance frequency analysis and the perio test, have been reported. 28 In general, when measuring bone structures, cortical and cancellous bones are independently evaluated, because their structure and turnover rates are completely different. 23 However, all these methods for implants do not separate the cortical and cancellous bone, because it has first reported before the modern histomorophological evaluations in the research field of bone metabolism has established.…”

Background Association between long‐term structural changes of grafted bone and outcomes of the implants is not clear. Purpose Morphometrical measurements and implant success were analyzed in subjects of particulate cellular bone and marrow (PCBM) reconstruction of the jawbone. Materials and Methods Subjects were 30 implants in 13 patients from a series of 24 PCBM reconstruction cases. The cortical bone thickness and cancellous computed tomography (CT) radiodensity values were retrospectively analyzed from the CT data of 27 subjects. The cumulative success rate of the implants in the PCBM reconstructed cases (pure graft) was compared with that of 127 implants of 56 native bone cases and 42 implants of 28 bone augmentation (partial graft) cases. Results In areas of PCBM reconstruction, cancellous CT radiodensity values were significantly high immediately after the surgery, and subsequently the values became stable. Cortical thickness was significantly increased, but did not reach that of native bone. Implant success rates were statistically not different (P = 0.783) between the native bone (91.3%), the partially grafted bone (95.2%), and the PCBM reconstructed bone (93.3%). Conclusion Implants in pure grafted bone are mainly supported by cancellous bone, because cortical thickness remained thin for a long period of time.
