This webinar will also show some hints, tips and tricks how to get around most of the limitations mentioned above, using additional materials and digital equipment.ĭigital and traditional impressions offer unique benefits and challenges. Other digital impressions limitations are because of the scanner size, the ability to capture only what the scanner can see, and decreased effectiveness when blood, saliva, or contamination are present in the oral cavity. ![]() ![]() Unstable soft tissue or insufficient hard tissue amount, especially taking impressions of long-span bridges or large/fullarch implant impressions. The more scans that are added, the more accurate the virtual model this is exactly the opposite of a traditional physical impression.įrom the other hand, there are some limitations in some clinical situations that still keep us doing analog impression procedures. Only the previously missing data is added to the model. Additional scans can be layered onto the inaccurate, voided image parts for enhanced visual representation. If an area is missed in the initial digital scan, digital impression systems allow the operator to “patch” the scan without retaking the entire impression. If necessary, additional partial scans can easily be made, creating better quality, artefact-less impression. The result obtained is far quicker, and it is possible to analyze the results of the scan immediately, during the same appointment. ![]() If there are errors, it is quick and easy to re-scan and correct the problem before sending the final impression. It creates a positive impression when the scan is complete, and with the ability to magnify the image, it is much easier to spot errors. The dentist will check for errors in the negative impression, but as it is inverted, unmagnified, spotting errors is more difficult, and if errors are detected, the patient will have to undergo the unpleasant procedure again. All of this makes it more likely that errors will occur. It involves many more steps than its digital counterpart, and utilizes multiple materials. The traditional method of taking dental impressions is a delicate process, requiring a lot of skill. These digital impressions are highly accurate and can be completed in minutes, with minimum discomfort for the patient. Modern advances in technology mean that dentists can now create virtual impressions of the hard and soft tissues in the mouth using scanning devices. This webinar will also show some hints, tips and tricks how to get around most of the limitations of the scanners, using additional materials, methods and digital equipment. When the scan is complete, and with the ability to magnify the image, it is much easier to spot errors. If detected, the patient will have to undergo the unpleasant procedure again.
