Digital innovations like intraoral scanners have changed the face of dentistry and enhanced patient care quality. While obtaining an intraoral scanner may make intuitive sense, clinicians might consider carefully how it impacts best practices and how well they can incorporate it with other aspects of their practices.

This article briefly explains what intraoral scanners are and how they enhance patient care and clinical best practices. We also discuss the factors dental professionals should consider when choosing and incorporating an intraoral scanner into their practices.

Benefits of an Intraoral Scanner in Modern Dentistry

An intraoral scanner is a handheld tool dental professionals use to capture images of a tooth’s asperities or imperfections to create a three-dimensional (3D) model through software processing. This technique replaces more traditional vinyl polysiloxane impressions. For example, a scanner can produce a 3D impression of a tooth with a cavity that a provider or patient can see from multiple angles.

The intraoral scanner represents the most innovative development in dentistry in recent years. Digital dentistry, with the help of scanning technology, makes three-dimensional printing or reproductions of prostheses possible. It also helps users better understand the nature and causes of various severities, which can inform proper treatment. Other benefits of intraoral scanning include:

• More comfortable for patients with gag reflexes
• Better infection control and increased hygiene
• More precise digital impressions that are easier to transmit to colleagues and labs for smoother collaborations and better workflows
• The ability to transmit images digitally without the use of stone models, which take more time to create
• Reduced time commitment by patients
• Increased image accuracy
• Cost savings due to eliminating the need for impression material and shipping expenses

When in the market for an intraoral scanner, a clinician should consider how well a particular device will fit into their unique practice, given the services they offer and the types and numbers of patients they serve. Several factors should be examined when choosing a scanner.

Intraoral Scanner Accuracy

Despite their use of the latest technology, most intraoral scanners vary in their accuracy levels, more specifically, the accuracy of the digital impression a scanner yields. When inquiring about a product, a provider might ask for measures on two elements:

• Trueness is the capacity of a tool to capture the validity or value of the thing it attempts to measure.
• Precision refers to consistently producing the same image with repeatable results.

Scanners also produce images using different formats. Wavefront object (OBJ) and polygon (PLY) files typically generate higher-quality and accurate models, making a precise mesh. In contrast, stereolithography (STL) file formats create 3D models with approximate mesh structures of the object. These approximations can diminish trueness, which is essential to consider for images used to make prostheses. However, clinical practices that treat many patients needing minor bridges or single-unit crowns may achieve adequate results with STL files.

Calibration of Intraoral Scanners

Intraoral scanners vary in how much calibration they need to be functional over multiple uses. If a dentist anticipates using the scanner relatively frequently or moving it from room to room, they may choose an instrument requiring minimal calibration or one with autocalibration.

Calibrating a 3D mouth scanner ensures accuracy by comparing measurements to a known reference object or points. The goal is to ensure that the scanner accurately measures the actual size of the object it is scanning.

You can do this by comparing the measurements to a known reference object or set of points. They call this process 3D calibration for an intraoral scanner. The objective is to synchronize the scanner’s data with the actual physical measurements of the object it is scanning.

Calibrating an intraoral scanner involves these steps:

1. Prepare the scanner and a calibration object following the manufacturer’s instructions.
2. Scan the object to create a 3D image using its shape, size, and pattern as a guide.
3. Compare the scanned data with the known dimensions of the object to find any differences.
4. Adjust the scanner’s settings based on the differences to improve accuracy.

Cost of Intraoral Scanners

A high-quality intraoral scanner is a significant investment, ranging from $19,000 to over $70,000. In addition to the initial scanner, some extra features and tools integrate with it and ongoing expenses. For example, most clinicians need a high-performing laptop that requires continual upgrades in addition to monthly or annual software subscriptions.

Also, most scanners are designed to accommodate supplemental features like orthodontic simulators. It’s always beneficial to consider the opportunity cost of such tools.

Factors Influencing Cost

1. Brand and Model: Various brands provide different degrees of technology, speed, and integration abilities. Top brands like 3Shape, iTero, and CEREC are more expensive because they have better features and are more reliable.
2. Features and Technology: Sophisticated features like high-resolution scanning, AI integration, color scanning abilities, and ergonomic design lead to increased costs. Scanners like iTero Element 5D, which can detect cavities using NIRI technology, usually cost more than basic models.
3. Scanners compatible with CAD/CAM systems for fabricating dental crowns and treatment plans might be more expensive. These scanners enhance the process’s efficiency and fluidity.
4. Software and Updates: Regular software updates and support services are crucial for better scanner performance. These recurring costs can affect the total investment.
5. Training and Support are crucial for dental staff to utilize the scanner effectively. Although they might be more expensive, they help maximize the scanner’s potential and efficiency.

Integrating Intraoral Scanners with Other Tools

An intraoral scanner’s capacity to integrate with other tools and systems in practice makes it more cost-efficient. In contrast, some scanners have a proprietary framework that prevents them from syncing with tools and software from other manufacturers or suppliers. Practitioners considering a particular intraoral scanner should check to see if it will interface with their current devices and frameworks, providing more flexibility and streamlined workflows.

Intraoral Scanner Design

Clinicians should pay attention to a scanner’s ergonomic design and its impact on the user and patient. Design features like tip size, the weight of the handheld scanner, and the ability to detach the tip can enhance or hinder the comfort of the scanning experience and affect the streamlining of the imaging process. Other design elements include wireless functioning, portability, and anti-fog capabilities.

Scanner Tip Sterilization

Health and hygiene should be a priority for all practices, regardless of patient volume. Providers should understand the sterilization methods that a scanner requires. For example, some scanners do not have detachable tips, requiring extra disinfection steps, such as cold sterilization or surface disinfectant wipes. Other scanners feature removable tips, allowing for more efficient sterilization and repeated use.

Scanner Speed

In an age of balancing speed of service and quality care, quickness in obtaining scans can save costs over time. Intraoral scanners vary in how quickly they capture a digital impression, and this difference is based on the following factors, all of which are necessary for a faster and smoother scan:

• The algorithm contributes to the speed of model stitching and fusion.
• Frame rate is the number of images a scanner’s built-in camera can take per second. However, taking more images increases the time necessary for point-cloud extraction.
• Image format is an aspect ratio issue or the number of extracted point clouds contributing to scan speed.

Software for Intraoral Scanners

Intraoral scanners come with software packages that help convert an initial scan to a 3D image. The ideal software system balances technological innovation and ease of use. The software interface should be intuitive, with the features on the portal being easy to navigate and manage. With the proper software design, clinicians can be more efficient in scanning and case management.

Customer Service and Support

No matter how well-designed or intuitive, an intraoral scanner should come from a manufacturer that backs up its product with excellent customer service, technical support, and repairs. Practitioners might ask manufacturers about virtual or on-site training included in the price.

Software and hardware issues are always possible, and it is essential to know what support a company offers, its customer service hours, and who is responsible for servicing the device and ancillary products.
