A difference between intraoral scanning and traditional impression taking is an essential topic for anyone looking to understand the options available in modern dentistry. While intraoral scanning uses advanced technology to capture digital images of the mouth, traditional impression taking involves the use of materials that can be uncomfortable. In this article, we will explore these differences and help you decide which method is best suited for your dental treatment.
What is Intraoral Scanning?
O intraoral scanning is a modern technique used in dentistry to create accurate digital impressions of the dental arch. This method uses a intraoral scanner, a camera-like device that captures 3D images of your teeth and gums.
During the procedure, the dentist moves the scanner around the patient’s mouth, capturing a series of images that are compiled into a digital model. This approach eliminates the need for physical molds, which can cause discomfort and anxiety.
One of the main advantages of intraoral scanning is the precision. Digital models are highly detailed, allowing more effective planning for treatments such as crowns, implants and orthodontic aligners.
Furthermore, scanning is a process fast and efficient. Capturing images usually takes just a few minutes, and the results can be viewed instantly, facilitating communication between the dentist and the patient.
Advantages of Intraoral Scanning
O intraoral scanning offers several significant advantages compared to traditional molding techniques. One of the main advantages is the patient comfort. By eliminating the use of impression materials that can be uncomfortable and cause nausea, scanning provides a more pleasant experience during the appointment.
Another important advantage is the accuracy of images. Intraoral scanning produces highly detailed digital models, which are essential for planning dental treatments. This precision contributes to more effective and long-lasting results.
Furthermore, scanning is a process fast. Capturing images takes just a few minutes, which reduces the total consultation time. This means less time in the dental chair and greater efficiency in care.
Scanning also allows a instant preview of the results. Dentists can show patients the images in real time, facilitating communication and understanding of the treatment plan to be carried out.
Finally, the use of digital technology simplifies the storage and sharing of impressions. Digital models can be easily stored in management systems, shared with other professionals and accessed at any time, increasing collaboration between dentists and specialists.
Disadvantages of Intraoral Scanning
Although the intraoral scanning present several advantages, there are also some disadvantages that patients and dentists should consider. One of the main disadvantages is the cost of the equipment. Intraoral scanners are advanced technologies and therefore can be quite expensive for dental clinics, which can be reflected in the prices of treatments.
Another disadvantage is the learning curve necessary for professionals. Although most dentists adapt quickly to the use of intraoral scanners, there may be an initial learning period in which the scanning efficiency may not be as high as that of traditional techniques.
Furthermore, patients with sensitive gums or who have difficulty opening their mouth may have difficulty during the procedure. Although the scan is generally more comfortable, some people may still experience discomfort during the process.
A dependence on technology is also a concern. In the event of equipment failures or technical problems, the procedure may be interrupted, which may cause delays in treatment and the need to revert to traditional methods temporarily.
Finally, the patient acceptance can be a barrier. Some patients may be more accustomed to traditional molding and may be hesitant to try new technologies, even if they offer benefits.
Traditional Molding: How Does It Work?
A traditional molding is a widely used method in dentistry to capture the shape of patients' teeth and gums. The process usually begins with the dentist applying an impression material, which can be a paste, gel, or silicone, to a tray, which is a frame that fits into the patient's mouth.
Once the tray is placed in the mouth, the dentist presses the material against the teeth and gums, allowing it to capture the exact shape of the dental arch. The patient needs to hold the position for a few minutes while the material hardens and takes the desired shape.
After hardening, the tray is carefully removed, resulting in a physical impression of the patient's mouth. This impression is then used to create plaster models or to be scanned for use in treatments such as crowns, dentures and orthodontic appliances.
While traditional molding is a proven and effective method, it can present some disadvantages, such as the discomfort the patient may feel during the procedure and the time needed for the material to harden.
Furthermore, the accuracy of the impression depends on the skill of the dentist and the quality of the material used. Imperfections in the impression can lead to problems with the fit of restorations or appliances, which may require new impressions and increase treatment time.
Accuracy Comparison Between Methods
A accuracy comparison between intraoral scanning and traditional impression taking is a crucial aspect in determining which method is most suitable for different dental treatments. Intraoral scanning, through advanced technology, produces highly detailed and accurate digital models, allowing a 3D visualization of the dental arch.
Studies have shown that intraoral scanning can offer a better accuracy compared to traditional impressions, especially in complex cases. The ability to capture fine details and the absence of distortions common in physical impressions are significant advantages of the digital method.
On the other hand, traditional molding can present variations in accuracy due to factors such as the dentist's technique, the time it takes for the material to set, and the patient's ability to maintain the position. Imperfections in the impression can result in inadequate adjustments of restorations, which can prolong treatment and increase costs.
Furthermore, the accuracy of intraoral scanning is often complemented by planning software, which help optimize and personalize treatment based on the data collected. These digital tools can further improve outcomes and patient satisfaction.
In short, while traditional impression taking is still a valid option, intraoral scanning tends to offer a superior accuracy, becoming the preferred choice for many dentists and patients seeking more effective and comfortable treatments.
