Digital scanners, or intraoral scanners, have become a transformative tool in modern dentistry. They replace traditional impressions with quick, accurate, and comfortable alternatives. These devices use optical sensors to capture high-resolution 3D images of teeth and gums, revolutionizing how dental professionals diagnose, plan treatments, and deliver care.
What Are Digital Scanners?
Digital scanners, also known as intraoral scanners, are
advanced devices used in dentistry to capture detailed, high-resolution 3D
images of a patient's teeth, gums, and oral structures. Unlike traditional
dental moulds (or impressions), which can be uncomfortable, messy, and
time-consuming, digital scanners use optical sensors to capture thousands of
data points per second, creating an accurate digital replica of the oral
cavity.
These scanners can capture intricate details of the teeth and surrounding tissues in a matter of minutes. The resulting digital impressions can be used for a wide range of applications, including designing crowns, bridges, dentures, and aligners, and even creating 3D models for surgical planning.
Advantages of Digital Scanners
1. Enhanced Patient Comfort
Traditional impressions often cause discomfort and gagging, but digital scanners use a small wand that scans the teeth and gums without the mess and discomfort of traditional moulds, offering a much more pleasant experience.
2. Increased Accuracy
Digital scans provide highly detailed, precise images, reducing the risk of errors and ensuring that restorations like crowns and bridges fit better, often eliminating the need for adjustments.
3. Faster Treatment
By sending digital data directly to labs, the design and production of restorations can be completed much more quickly. In some cases, same-day restorations are possible, reducing the need for multiple appointments.
4. Efficient Storage
Digital impressions eliminate the need for physical storage of moulds, allowing dental practices to keep digital records of patient scans for easy access and future reference.
5. Environmentally Friendly
With less reliance on disposable materials like alginate, digital scanning is a more sustainable option for dental practices.
Applications in Dentistry
Digital scanners
are versatile tools used across various dental specialties:
·
Restorative Dentistry: For creating precise crowns, bridges, and
veneers.
·
Orthodontics: Diagnosis and treatment planning of orthodontic models, aligners, and
appliances
·
Implantology: Helps plan accurate implant placements.
· Prosthodontics: Optimises the design and fit of dentures and prosthetics.
