This study presents an open protocol for evaluating dental implant deviation using digital casts. The method easily integrates with guided surgery and digital prosthodontics workflows, improving accuracy.
Area of Science:
- Dentistry
- Biomedical Engineering
- Digital Health
Background:
- Accurate dental implant placement is crucial for successful prosthodontic outcomes.
- Current methods for evaluating implant deviation can be limited by closed-loop software workflows.
- Digital workflows in dentistry offer potential for improved precision and efficiency.
Purpose of the Study:
- To describe an open protocol for evaluating dental implant deviation using digital casts.
- To provide a method that is easily integrated into existing clinical and digital prosthodontic workflows.
- To overcome the limitations of proprietary software in assessing implant accuracy.
Main Methods:
- Utilizing reverse engineering software to analyze digital surgical planning and definitive casts.
- Creating simplified cylindrical representations of implants within the software.
- Superimposing digital casts to calculate implant deviations based on cylinder coordinates.
Main Results:
- The protocol allows for the calculation of implant deviations by comparing digital cast data.
- The method relies on routine clinical data from guided implant surgery.
- The protocol is adaptable to various dental software programs that provide implant coordinates.
Conclusions:
- An open and adaptable protocol for evaluating dental implant deviation has been established.
- This method facilitates the integration of implant accuracy assessment into standard digital dental workflows.
- The protocol offers a solution to the limitations imposed by closed-loop software systems in dental implantology.
