Are digital scans more accurate than traditional impressions?

Introduction

When it comes to getting dentures, one of the first steps is taking an impression of your mouth. This impression is then used to create dentures that fit your mouth perfectly. Traditionally, this has been done using a physical mould, but with the advent of advanced technology, digital scans are becoming increasingly popular. So, the question arises: are digital scans more accurate than traditional impressions?

Understanding Traditional Impressions

Traditional impressions involve using a tray filled with a soft material that takes the shape of your mouth when pressed against your teeth and gums. This impression is then used to create a model of your mouth, which is used to make your dentures. There are different types of dentures such as acrylic, chrome, flexible (Valplast), injection moulded, and 3D printed options. The lifespan of these dentures can vary. Standard acrylic dentures last 1–3 years, high-impact acrylic can last 3–5 years, chrome can last 8–12 years, and flexible dentures can last 3–5 years. The cost of these dentures can also vary depending on the type and provider, and you can find more information about this here.

Understanding Digital Scans

Digital scans, on the other hand, involve using a handheld device that takes thousands of photos of your mouth in a matter of minutes. These images are then stitched together to create a 3D model of your mouth. This model is then used to create your dentures.

The Accuracy of Digital Scans versus Traditional Impressions

So, are digital scans more accurate than traditional impressions? In general, digital scans are considered to be more accurate than traditional impressions. This is because digital scans can capture every tiny detail of your mouth, including the smallest crevices and contours, which can often be missed by traditional impressions. This leads to dentures that fit more accurately and comfortably.

The Advantages of Digital Scans

Beyond accuracy, there are several other advantages to using digital scans. For one, digital scans are faster and more convenient. They can be completed in a matter of minutes, and there’s no need for you to sit with a tray in your mouth. Digital scans are also more comfortable, as there’s no need for physical contact with your mouth. Furthermore, digital scans are more environmentally friendly, as they don’t require the use of physical materials.

The Limitations of Digital Scans

However, digital scans do have their limitations. For one, not all dental practices have the necessary equipment to perform digital scans. Furthermore, while digital scans are generally more accurate, this does not necessarily mean they will lead to better fitting dentures. The fit of your dentures also depends on the skill and experience of the dental technician who creates them. Therefore, it’s important to choose a dental practice that has experience with both traditional impressions and digital scans, such as the Smiles Centre.

Conclusion

In conclusion, while digital scans are generally more accurate than traditional impressions, the best method for you will depend on your individual needs and circumstances. It’s important to discuss your options with a dental professional, such as a dentist or a Clinical Dental Technician, to ensure you get the best possible results. Remember, regardless of the method used to create your dentures, regular denture care, including relines and adjustments, is crucial to maintaining their comfort and longevity.
