Summary
Operator experience significantly impacts digital implant impression accuracy. While angulation and depth had minor effects, training is crucial for optimal results with these advanced dental technologies.
Area of Science:
- Dental Technology
- Digital Dentistry
- Implantology
Background:
- Limited data exists on the accuracy of intraoral digital impression systems for dental implants.
- Evaluating the precision of digital impressions is critical for successful implant restorations.
Purpose of the Study:
- To assess the accuracy of a specific digital impression system under various clinical conditions.
- To investigate the influence of operator experience, implant angulation, and depth on impression accuracy.
Main Methods:
- A master model with six implants, including angulated and varying depths, was used.
- Scans were performed by experienced and inexperienced operators using a Lava Chairside Oral Scanner in standard and high accuracy modes.
- Measurements were compared against a high-accuracy coordinate measuring machine (CMM) for true values.
Main Results:
- Operator experience was a significant factor influencing the accuracy of digital impressions (p=.000).
- Implant angulation (p=.195) and depth (p=.399) did not show statistically significant deviations from true values.
- The average difference between standard and high accuracy modes was 90 μm.
Conclusions:
- Training on technology-based digital impression systems is recommended for optimal performance.
- While angulated implants may potentially reduce accuracy, this study found no significant impact.
