Exploring Digital Scanning Tools in Dentistry
Dental digital scanners can be broadly categorized based on their application location and usage: either directly in the clinic with the patient or in dental laboratories, away from direct patient interaction. For in-clinic use, scanners can be distinguished as CBCT and intraoral scanners. Dental Cone Beam CT (CBCT) scanners specialize in capturing X-rays of the oral region. On the other hand, intraoral or 3D dental scanners present a modern alternative to traditional impressions, eliminating the need for patients to uncomfortably sit with a mouthful of viscous impression material. Notably, both scanning methods can be integrated, particularly when comprehensive denture procedures are required.Constructed from polygons, intraoral scans can be seamlessly merged with images captured by an intraoral camera. This synthesis yields a detailed 3D representation of the patient’s dental structure, showcased on a digital screen or tablet. Such precision empowers dentists to identify the minutest of dental imperfections and anomalies, some of which might be indiscernible to the human eye. Remarkably, certain advanced scanners possess the capability to detect early signs of cavities, offering a proactive approach to halting their progression.
Face scanner

A “face scanner” or facial scanning is a type of 3D scanning technology that captures detailed images of the patient’s face, teeth, and sometimes the entire head. This technology can be used for a variety of dental applications:

  • Diagnostic Purposes: Dentists can use 3D facial scans to assess facial symmetry, study the relationships between facial structures, or monitor the effects of certain treatments over time.
  • Treatment Planning: Orthodontists can use facial scans in conjunction with digital dental scans to plan orthodontic treatments that not only align the teeth but also harmonize with the patient’s facial aesthetics.
  • Surgical Planning: Maxillofacial surgeons can use these scans to plan surgeries, visualize outcomes, and create surgical guides.
  • Prosthodontic and Restorative Dentistry: Dentists can integrate facial scans with intraoral scans to design restorations, dentures, or dental implants that are in harmony with the patient’s facial features.
  • Simulation and Patient Education: By having a 3D image of the patient’s face and teeth, dentists can simulate potential treatment outcomes. This can be a powerful tool for patient education, as individuals can see what they might look like after treatment.
  • Integration with Digital Smile Design (DSD): This is a treatment planning protocol that uses both functional and aesthetic considerations. Facial scanning allows dentists to see how proposed changes to the teeth can affect overall facial aesthetics.

The technology behind these scanners often involves structured light or laser scanning to create accurate 3D models. These models can then be manipulated and studied using specialised software.

Face scanners in dentistry are part of the larger movement towards digital dentistry, where traditional methods are being complemented or replaced by digital techniques, allowing for more precision, efficiency, and possibilities in patient care.

MODJAW
MODJAW, a major technological advancement, provides us with a real-time and 4-dimensional view of the movements of the jaw. While traditional techniques are limited to static images in 2D or 3D, MODJAW offers a dynamic understanding of how the jaw functions when the patient speaks, eats, or simply smiles.The process begins with data acquisition. We simply use a sensor that records jaw movements while you perform natural actions, such as opening and closing the mouth or moving the jaw from left to right and front to back.This data is then analysed by specific software, which creates a dynamic 4D simulation of the jaw movements. Here’s where the magic happens: the dentist can view these movements in real-time, from all possible angles, on a screen. This provides the dentist with a deep understanding of the unique anatomy and its functionality.
