Intraoral scanners utilize either laser or optical technology to capture images of the teeth and surrounding tissues, creating accurate 3D models. These scanners are particularly beneficial for chairside restorations, ensuring quick turnaround times and reducing patient discomfort compared to traditional impressions.

2. Desktop Scanners: Desktop scanners, as the name suggests, are larger in size and are typically used in dental laboratories. They are capable of scanning a wide range of dental impressions, including stone models, wax patterns, and gypsum casts. Desktop scanners utilize advanced laser or structured light technologies to capture highly detailed 3D images, offering excellent precision and versatility. These scanners are ideal for complex restorative cases that require extensive planning and meticulous fabrication.

3. Hybrid Scanners: Hybrid scanners combine the advantages of both intraoral and desktop scanners, offering a versatile solution for dental professionals. These scanners can be used intraorally or as a desktop unit, providing flexibility and convenience. Hybrid scanners offer the ability to quickly capture patient impressions chairside and seamlessly transition to the dental laboratory for further design and fabrication. This versatility makes hybrid scanners suitable for both chairside restorations and complex prosthodontic procedures.

The Working Principles of Dental Laboratory Scanners:

Dental laboratory scanners employ advanced imaging technologies to capture precise digital impressions. Depending on the type of scanner, different working principles are utilized. Here, we explore the working principles of three common dental laboratory scanners:

1. Laser Technology: Laser scanners use a laser beam to scan the surface of the dental impression, measuring the distance between the scanner and the object. This scanning process produces a cloud of data points, which are then used to construct a 3D model. By scanning the impression from multiple angles, laser scanners capture the intricate details of the teeth, gingival tissues, and surrounding structures with high accuracy.

2. Optical Technology: Optical scanners use a combination of cameras and projectors to capture digital impressions. The object is illuminated with fringe patterns, which are captured by multiple cameras from different angles. Based on the distortion of these patterns, the scanner calculates the shape and depth of the object's surface, generating a precise 3D model. Optical scanners are known for their excellent color reproduction and ability to capture highly detailed impressions.

3. Structured Light Technology: Structured light scanners project a series of light patterns onto the dental impression, which are then captured by cameras. These patterns create a unique surface texture and depth that allows for accurate measurement and reconstruction of the object. Structured light scanners are popular for their speed and high-resolution capabilities, making them ideal for time-sensitive cases and complex restorations.

The Applications of Dental Laboratory Scanners:

Dental laboratory scanners find a multitude of applications in modern dentistry, revolutionizing various aspects of patient care and treatment planning. Here are some key applications:

1. Restorative Dentistry: Dental laboratory scanners play a vital role in the fabrication of crowns, bridges, veneers, and other restorative dental prosthetics. By capturing precise digital impressions, scanners ensure optimal fit, function, and aesthetics of the restorations, eliminating the inaccuracies of traditional impressions. Additionally, the digital workflow allows for seamless communication between the dental clinician and the dental laboratory, enhancing collaboration and ensuring patient satisfaction.

2. Orthodontics: Dental laboratory scanners have transformed the field of orthodontics by enabling the creation of accurate digital models for orthodontic treatment planning. Instead of taking cumbersome physical impressions, scanners capture digital impressions of the patient's teeth, allowing orthodontists to visualize tooth movements and plan treatment more precisely. This technology has revolutionized the field of clear aligner therapy, such as Invisalign, by providing a digital workflow for designing and fabricating aligners.

3. Implant Dentistry: Precise implant placement is critical for successful implant dentistry. Dental laboratory scanners aid in accurately capturing the patient's oral anatomy for planning implant surgeries. By overlaying digital impressions onto cone-beam computed tomography (CBCT) scans, scanners assist in virtual implant placement and creating surgical guides. This seamless integration between scanners and CBCT allows for safe and efficient implant surgeries with optimal esthetic and functional outcomes.

4. Prosthetic Fabrication: Dental laboratory scanners are widely used in the fabrication of custom removable prosthetics, including complete dentures, partial dentures, and implant-supported removable prostheses.
