![]() The digital technology captures a coherent and structured impression of the oral tissues that can then be transmitted to computer software. Digital impressions optimize cutting-edge technology that allows dentists to create a computer-generated virtual replica of the hard and soft tissues of the oral cavity using lasers and other optical scanning devices. What are digital impressions?Ī digital impression is a virtual scan that creates a map of the oral cavity. This guarantees the benefits of both the theories the best of both worlds. Another type of impression technique, known as the select pressure technique is focused on delivering relief to stress relief areas and compression to the stress-bearing areas. As a result, a denture most stable at function but not at rest is accomplished. Mucocompressive theory, on the other hand, is related to taking impressions when the mucosa is subject to compression. Although these impressions are generally affiliated with great fit and accuracy, the denture is more likely to pivot around compressive areas such as the torus palatinus, during chewing. ![]() Mucostatic theory follows the impression being taken of the mucosa when in its normal resting position. The principle of impression-taking abides by either of these two theories of denture appliance fabrication- the mucostatic theory and the mucocompressive theory. This impression is then aptly coerced into the fabrication of necessary dental appliances that fulfill a patient’s dental needs. ![]() It is a preliminary step in which a stock or custom dental impression tray is loaded with appropriate material (commonly used hydrocolloids like agar or alginate) that is specially designed to roughly engage the oral structures and fit over the dental arches. What is a dental impression?Ī conventional dental impression is a negative imprint of the hard and soft tissues in the mouth, recording of which can generate a positive reproduction (cast or model). With the rapid integration of technology for prosthetic marketing, dentists have been adopting a high-yielding system of immediate dental restorations based on digital impressions and workflow that prioritizes patient control and convenience. Fabrication of dentures and other prostheses by means of computer-aided design (CAD) and computer-aided manufacture (CAM) has not only proven to be possible but may have readily revolutionized the world of dental prosthetics. Among many biometric systems implemented in the two cardinal fields of prosthodontics and implantology, rehabilitation of partially or fully edentulous patients has become substantially easier and precise. During the past decade, prosthetic dentistry has positively been shaped and impacted by computer-driven technologies that situate a level of desirable comfort and efficacy for the dentist and patients alike.
