This discussion will delve further into the specific components of these systems, exploring the various scanning technologies, design software capabilities, and manufacturing processes employed. Subsequent sections will also address the clinical applications, material options, and economic considerations associated with this technology.
1. Digital Impression Accuracy
Digital impression accuracy represents a foundational element in the effective application of systems. The initial digital scan serves as the blueprint for all subsequent design and manufacturing processes. An inaccurate digital impression, characterized by distortions, incomplete data capture, or artifacts, directly translates into a flawed virtual model. This flawed model then compromises the fit, function, and aesthetics of the final restoration or appliance fabricated using this process. Consider, for example, a crown designed from a scan with marginal discrepancies. The resultant crown will likely exhibit poor marginal adaptation, potentially leading to microleakage, recurrent decay, and ultimately, restoration failure. The precision of the system is therefore entirely dependent on the fidelity of the initial digital impression.
Furthermore, the accuracy of digital impressions impacts the efficiency of the entire workflow. Inaccurate impressions necessitate repeated scanning, adjustments to the digital design, and potentially, remakes of the restoration. These iterative steps increase chair time, laboratory costs, and patient inconvenience. Conversely, a highly accurate digital impression streamlines the process, minimizing the need for adjustments and ensuring a more predictable outcome. Examples include implants restoration and full arch restoration, where initial misfit results expensive and long time remakes
In conclusion, the accuracy of the digital impression is not merely a desirable feature but a critical determinant of success.
