Dental technology is rapidly evolving, with 3D digital scanners replacing traditional impression methods in practices across the country. For example, digital techniques for 3D impressions are increasingly popular within the dental community. This improves the quality of dental work, the economics of dental practice, and the overall experience of patients. This is a method that captures many small images of the teeth and converts them into a 3D model, replacing traditional impressions that utilize a putty-like substance called alginate, which is becoming increasingly outdated. The technology takes the form of a wand-shaped camera that captures thousands of tiny images, revolutionizing impressions altogether.
- How Traditional Dental Impressions Work and the Limitations
Traditional dental impressions suffer from several significant drawbacks. The primary issue is the multi-step approach required for traditional models. The process involves multiple steps: first, dentists take physical impressions and make adjustments. Then, the impressions are complete, they are sent to a dental lab to create models of the patient’s teeth. Next, a wax model is created and used to form a mold that can be filled with dental materials. Finally, the impression is polished and adjusted.
These manual processes lead to longer turnaround times and extended wait times for patients. Additionally, the risk of inaccuracy is higher due to manual adjustments and labor. The use of physical materials can also lead to waste and inefficiencies.
- The Unique Advantages of 3D Digital Scanners
However, 3D digital scanners offer several key advantages over traditional methods. For example, they are highly accurate. 3D imaging allows for extremely detailed capture of the mouth. The process of 3D scanning is as follows:
- Patient information is entered
- Upper and lower arches are scanned
- A bite scan captures alignment
- Digital files are transmitted for processing and treatment planning
Additionally, the process is faster and less invasive for both patients and dental professionals. 3D scanning also allows for easier sharing of information and collaboration among dental teams. Specifically, scans can easily be sent to labs and processed efficiently, they replace the physical and fragile material used in traditional impressions, and replace them with digital files quickly and safely. Communication with patients is also improved, as scans are easily viewable and enhance understanding.
- Benefits for Patients and Dentists
From the patient perspective, the improvements are particularly noticeable. For example, traditional impressions are often uncomfortable and stressful during dental procedures. This is because the alginate or putty-like material used for traditional impressions is thick and can easily trigger gag reflexes. The material also requires patients to hold still for several minutes while the impression cures, with their mouths still uncomfortably full. In turn, the putty-like material (alginate) used for impressions can be difficult to tolerate and may complicate the procedure.
In contrast, 3D scanning improves patient comfort and efficiency. It is also highly beneficial for dentists, as it allows for greater precision while minimizing disruption to the patient. Additionally, dentists are able to easily share and analyze scans in a more efficient and effective way.
- Current Barriers to Adoption of Use
Despite these advantages, 3D scanning technology faces adoption challenges. The equipment is initially very expensive. Additionally, dentists must complete specialized training programs, which can take weeks and cost thousands of dollars. There is also the possibility of hardware malfunctions, which can be unpredictable and less reliable than traditional physical impressions in terms of equipment failure.
3D impression technology allows for less invasive and more accurate and accessible impressions. The future of dental impressions will be defined as the more efficient and less invasive technology. Additionally, dentists and dental students should continue to practice and develop their skills with 3D technology as it becomes more integrated into the field. And soon, patients too should follow suit and opt for the more comfortable impression option.
