Digital Technologies, Materials and Telemedicine in Dentistry

As we delve into this Special Issue on prosthesis, it is evident that digital dentistry continues to revolutionize the field, offering improved precision, efficiency, and patient satisfaction. This editorial aims to provide an overview of the key findings presented in this issue, focusing on the advances in digital impression techniques, computer-guided surgeries, and the integration of CAD/CAM technologies.

One of the significant advancements highlighted is the precision of intraoral scanners (IOS) compared to conventional impression methods [1,2]. Studies have demonstrated that digital impressions, when performed correctly, offer comparable, if not superior, accuracy to traditional methods. For instance, the research by Mangano et al. [3] investigated the accuracy of digital versus conventional impressions and found that, despite notable angulation and distance errors in partially edentulous cases, digital technology still proved to be a viable option in numerous situations [4,5].

Additionally, utilizing open-source software for 3D model superimposition has demonstrated promising outcomes in enhancing workflow efficiency in dental practices [6]. This is particularly evident in the study on the Medit i500 intraoral scanner, which demonstrated high precision in full-arch scans, with deviations well within clinically acceptable limits [7]. The ability to capture detailed digital impressions quickly and accurately not only streamlines the clinical workflow but also enhances the patient experience by reducing the discomfort associated with traditional impression materials [7,8].

Computer-guided surgery has become a cornerstone in implantology, reducing intraoperative complications and enhancing the accuracy of implant placement. The integration of cone-beam computed tomography (CBCT) with digital planning software allows for meticulous pre-surgical planning, which is crucial for avoiding anatomical structures and ensuring optimal implant positioning [9,10,11].

A study illustrated in this issue highlights the benefits of merging digital and freehand techniques [12]. The mixed approach, combining initial digital planning with manual adjustments, was shown to increase the accuracy and predictability of implant placement, especially in challenging anatomical regions like the maxillary sinus. This hybrid approach allows clinicians to leverage the precision of digital planning while maintaining the flexibility to make intraoperative adjustments based on real-time observations and patient-specific anatomical variations [13,14]. The use of CAD/CAM technologies has significantly streamlined the prosthetic fabrication process. Digital workflows allow for precise design and manufacturing of prosthetic components, reducing the time and potential errors associated with manual techniques [15]. A study comparing the fit accuracy of CAD/CAM frameworks to traditionally manufactured ones found that digitally produced frameworks exhibited superior precision, particularly when all screws were fastened [16]. The digital production and customization of facial orthopedic devices, such as chin cups, have shown promising results in terms of patient comfort and appliance accuracy. Digital workflows, including facial scanning and 3D printing, provide a higher degree of customization, which is crucial for patient compliance and treatment efficacy [17]. The use of non-invasive 3D face scanning technology allows for the creation of prosthetic components that are tailored to the patient’s unique anatomical features, further enhancing the fit and comfort of the final product [17]. Additionally, these technologies have the potential to reduce costs and improve the overall patient experience compared to traditional analog methods.

Furthermore, the complete digital workflow, from intraoral scanning to the creation of a three-element fixed partial prosthesis, showcases how traditional concepts can be seamlessly adapted to modern technologies. This approach not only enhances the accuracy and esthetics of the final prosthetic product but also improves patient comfort and satisfaction. Integrating digital tools throughout the treatment process allows dental professionals to achieve higher precision and consistency, crucial for long-term success and patient satisfaction [18,19].

The progress in CAD/CAM technology also underscores the necessity of ongoing education and training for dental professionals. As digital tools become more sophisticated, staying updated with the latest techniques and software capabilities is essential for maximizing their benefits in clinical practice [19,20]. This ongoing professional development ensures that clinicians can effectively utilize these technologies to enhance patient care and outcomes. Patient satisfaction remains a critical factor in the adoption of digital technologies. Studies included in this issue consistently show a preference for digital impressions over conventional methods, primarily due to reduced discomfort and faster procedure times.

Nevertheless, it is important to recognize the limitations and variability in study designs that can affect outcomes. Variations in scanners, study settings, and patient demographics need to be taken into account when interpreting these results. Despite these challenges, the overall trend indicates a positive shift toward digital solutions in prosthetic dentistry [21]. Understanding patient preferences and experiences with digital technologies can assist clinicians in selecting the most appropriate tools and techniques for their practice, thus enhancing patient care and satisfaction [21,22].

Although the benefits of digital dentistry are clear, several challenges must still be addressed to fully realize its potential. One significant issue is the integration of various digital tools and systems within dental practices [18]. Achieving compatibility and smooth data transfer between various software and hardware components are crucial for establishing an efficient and effective digital workflow [23].

Furthermore, the expense of purchasing and maintaining advanced digital equipment can pose a significant challenge for many dental practices [24,25]. Investments in intraoral scanners, CAD/CAM systems, and computer-guided surgery tools require significant financial resources. As the technology becomes more prevalent and competition increases, costs are anticipated to drop, thereby becoming more affordable for a wider array of practitioners [26].

Another critical factor is the need for rigorous training and education for dental professionals. The swift progression of digital technologies demands ongoing education to stay abreast of new advancements and to ensure that clinicians can proficiently use these tools in their practice [27,28]. Dental schools and professional organizations need to prioritize integrating digital dentistry into their curricula and continuing education programs to provide practitioners with the essential skills and knowledge [29,30].

The articles in this Special Issue collectively underscore the transformative impact of digital technologies in prosthetic dentistry. The shift toward digital workflows not only enhances clinical accuracy and efficiency but also improves patient experiences. As these technologies advance, ongoing research and clinical trials will be crucial to perfect their use and unlock their full potential in dental practice. By adopting the innovations in digital dentistry and tackling the related challenges, the dental community can anticipate a future where patient care becomes more accurate, efficient, and fulfilling.
