To Study the Influence of Digital Dentistry on the Accuracy of Implant Positioning and Prosthesis Creation

Aims and background: To study the influence of digital dentistry on the accuracy of implant positioning and prosthesis creation.Materials and methods: This in vitro study was conducted to assess the impact of digital dentistry on the precision of implant placement and the accuracy of prosthesis fabrication.For this study, 50 partially edentulous maxillaries and mandibular typodont models were selected.These models were randomly divided into two groups: The digital dentistry group (n = 25) and the conventional group (n = 25).In the digital dentistry group, cone-beam computed tomography (CBCT) scans and intraoral scans were performed on the typodont models.The data from these scans were imported into specialized dental implant planning software to facilitate virtual implant planning.Implant positioning, angulation, and depth were determined by considering optimal prosthetic outcomes alongside anatomical constraints.Results: The digital dentistry group showed significantly lower mean deviations in all parameters coronal, apical, global, angulation, and depth compared to the conventional group.For example, the mean coronal deviation in the digital dentistry group was 0.30 mm compared to 0.60 mm in the conventional group (p = 0.001).Similarly, the apical deviation was 0.40 mm in the digital group vs 0.70 mm in the Conventional group (p = 0.002).These results indicate that the digital approach provided more precise implant placement.The digital dentistry group exhibited significantly better fit, with a mean marginal discrepancy of 25 m compared to 40 m in the conventional group (p = 0.004).Similarly, the internal fit discrepancy was 30 m in the digital group vs 45 m in the conventional group (p = 0.005).These findings suggest that digital methods not only improve the accuracy of implant placement but also enhance the fit of the prosthesis.A better fit reduces the likelihood of complications such as microleakage, peri-implantitis, and long-term mechanical failures, thereby improving the longevity and success of the implant-supported prosthesis. Conclusion:The digital approach resulted in more precise implant placement, better prosthesis fit, and shorter procedure times, all of which contribute to improved patient outcomes and higher clinical efficiency.The statistical analysis supports these findings, confirming the significance of the observed differences.These results suggest that digital workflows should be considered a preferred method in implant dentistry for achieving optimal results.
