What are the current trends and challenges in CAD/CAM dentistry?

1 Digital impressions

One of the key trends in CAD/CAM dentistry is the adoption of digital impressions, which are images of the teeth and gums captured by a scanner. Digital impressions eliminate the need for conventional impression materials, trays, and models, which can be uncomfortable, messy, and time-consuming. They also allow for faster and more accurate communication and collaboration between the dentist and the lab technician. However, digital impressions require proper training, maintenance, and calibration of the scanners, as well as adequate storage and security of the data.

2 Chairside milling

Another trend in CAD/CAM dentistry is the use of chairside milling, which is the fabrication of dental restorations in the dental office using a milling machine. Chairside milling enables the dentist to deliver the restoration in a single visit, saving time and costs for both the dentist and the patient. It also allows for more customization and control over the design and quality of the restoration. However, chairside milling involves high initial investment, ongoing maintenance, and materials costs, as well as technical skills and quality assurance.

3 Materials and aesthetics

A third trend in CAD/CAM dentistry is the development and use of new materials and techniques to enhance the aesthetics and durability of dental restorations. Some of the materials used in CAD/CAM dentistry include ceramics, composites, metals, and hybrid materials, each with their own advantages and disadvantages. Some of the techniques used to improve the aesthetics of CAD/CAM restorations include staining, glazing, polishing, and layering. However, materials and aesthetics also depend on the patient's preferences, expectations, and oral conditions, as well as the dentist's experience and judgment.

4 Integration and interoperability

A fourth trend in CAD/CAM dentistry is the integration and interoperability of different systems and software to facilitate the workflow and communication of CAD/CAM dentistry. For example, some systems and software can integrate digital impressions, CAD software, milling machines, 3D printers, and intraoral cameras to create a seamless and efficient process. However, integration and interoperability also pose some challenges, such as compatibility issues, data transfer errors, and software updates.

5 Education and research

A fifth trend in CAD/CAM dentistry is the advancement and dissemination of education and research in this field. For example, some dental schools and associations offer courses, workshops, webinars, and certifications on CAD/CAM dentistry to train and update dental professionals on the latest technologies and techniques. Some also conduct and publish research on the clinical outcomes, patient satisfaction, cost-effectiveness, and ethical implications of CAD/CAM dentistry. However, education and research also require resources, funding, and collaboration among various stakeholders.

6 Ethics and regulation

A sixth trend in CAD/CAM dentistry is the emergence and discussion of ethical and regulatory issues related to this field. For example, some ethical and regulatory issues include the ownership, privacy, and security of patient data; the quality and safety of CAD/CAM restorations; the responsibility and liability of dental professionals; the informed consent and autonomy of patients; and the social and environmental impact of CAD/CAM dentistry. However, ethics and regulation also require awareness, dialogue, and consensus among different parties.
