Post-Processing Requirements: Many 3D-printed prosthetics need additional steps like curing or polishing after printing ^[19].

Intraoral Scanners in Prosthodontics

Overview of Intraoral Scanning Technology:

Intraoral scanners use optical technology to capture detailed digital impressions of teeth and oral structures, pivotal in modern prosthodontics for non-invasive and accurate dental impressions

Clinical Applications:

Digital Impressions: Intraoral scanners replace traditional impression materials with digital imaging, offering a comfortable and efficient alternative ^[20]

Treatment Planning: Enhanced visualization aids in treatment planning and patient communication ^[21]

Monitoring: Regular scans track dental structure changes over time, aiding in preventive care and early issue detection ^[22]

Benefits:

Patient Comfort: Digital impressions eliminate the need for conventional materials, enhancing patient comfort ^[20]

Accuracy: Intraoral scanners provide highly precise digital impressions ^[23]

Speed: The scanning process is quick, and digital files can be immediately transferred for further processing ^[2]

Impact on Clinical Practice

The integration of these digital technologies into prosthodontic practice has numerous benefits:

• Improved Diagnosis and Treatment Planning: Enhanced imaging and design capabilities facilitate better diagnosis and more precise treatment planning ^[22]
• Enhanced Patient Communication: Digital models and simulations can be used to better communicate treatment plans to patients, improving understanding and acceptance ^[21]
• Predictable Outcomes: The precision & customization offered by digital technologies lead to more predictable clinical outcomes and higher patient satisfaction ^[24]

Future Directions

As digital technology continues to evolve, its applications in prosthodontics will expand. Future advancements may include:

• Artificial Intelligence (AI): Integrating AI in digital dentistry could further enhance diagnostic accuracy and treatment planning ^[25]
• Augmented Reality (AR) and Virtual Reality (VR): These technologies have the potential to revolutionize dental education and patient consultations
• Bioprinting: The development of bioprinting techniques could enable the creation of prosthetic components with biological materials ^[26]

CONCLUSION

The adoption of CAD/CAM systems, 3D printing, and intraoral scanners has brought about a profound transformation in prosthodontic procedures, delivering substantial advantages in accuracy, productivity, and patient convenience. These technological strides have not only elevated the standard of dental restorations but also enriched the overall patient journey. As digital innovations progress, their integration within prosthodontic practices is poised for further growth, promising increasingly inventive and efficient dental therapies.
