Precision Analysis of Prosthetic Abutment Couplings on Megagen® Dental Implants Using MicroCT

Dental implants have revolutionized dental restoration, offering unparalleled functionality and aesthetics. However, the longevity and success of these implants are critically dependent on the precision of prosthetic abutment couplings. Micro-computed tomography (microCT) has emerged as a vital tool in assessing these parameters, providing detailed insights into the structural integrity and fit of dental components. This study aims to evaluate the precision of the couplings between prosthetic abutments and healing screws on Megagen® AnyOne® dental implants using microCT.

The investigation utilized the microCT technique with specific parameters: an optical axis of 502, an object-to-source distance of 226.60 mm, a camera-to-source distance of 266.50 mm, a source voltage of 50 kV, a source current of 800 µA, and an image pixel size of 18.20 µm. The samples analyzed included Megagen® AnyOne® implants with dimensions of 4x10 mm and 4x5 mm, tightened at 5-8 Ncm using a digital torque gauge. This study focused on identifying the presence of air gaps and the precision of the couplings through detailed three-dimensional reconstructions and radiographic evaluations.

The microCT analysis revealed no presence of air gaps or radiographic discrepancies in the couplings between the prosthetic abutments and the healing screws. The fixture dimensions were consistent with the expected standards, with a length of 9.347 mm and a radiographic width of 3.914 mm. The three-dimensional reconstructions confirmed the absence of communication between the external and internal environments of the implant connection, underscoring the precision and reliability of the Megagen® AnyOne® implants.

This study confirms the high precision and reliability of the Megagen® AnyOne® dental implants in the coupling of prosthetic abutments and healing screws. The absence of air gaps and the congruence of fixture dimensions with expected standards highlight the exceptional quality of these implants. Future research should focus on longitudinal studies to assess the long-term clinical outcomes and potential improvements in microCT technology to further enhance diagnostic capabilities.
