Artificial Intelligence and Mixed Reality in Implant Dentistry
Abstract:
Two emerging technologies promise to radically transform the field of implant surgery: Artificial Intelligence (AI) and Mixed Reality (MR).Artificial Intelligence refers to software or computer systems capable of solving complex problems that would traditionally require human cognition and intervention. In dentistry, AI is now widely used for the automated detection and diagnosis of caries as well as endodontic, cystic, and periodontal lesions on two-dimensional radiographic images, including intraoral and panoramic radiographs. More recently, AI has been applied to the automated identification and segmentation of anatomical structures in three-dimensional imaging modalities, such as cone-beam computed tomography (CBCT). These capabilities are enabled by machine learning, a process through which computers learn from data by identifying intrinsic statistical patterns and structures. Today, AI-powered software can even automatically plan dental implant placement. Mixed Reality, in contrast, is a technology capable of generating high-definition virtual content and three-dimensional models (holograms) that are superimposed onto the real environment, thereby enhancing and augmenting the user’s perception of reality. A hologram is a three-dimensional virtual model generated through advanced projection technologies. The clinician wears a headset with transparent lenses that overlays virtual objects onto the real world, effectively augmenting it. While remaining fully aware of and engaged with the physical environment, the operator can simultaneously interact with these virtual objects. Currently, MR plays a crucial role in presenting treatment plans to patients, facilitating remote collaboration among dental professionals (dentists and dental technicians), and supporting implant surgery planning. The ultimate evolution of these technologies lies in dynamic guided implant surgery, holographically controlled and driven by Artificial Intelligence: the mixed reality based dynamic navigation.
Chairside 3D Printed Definitive Restorations
Abstract:
Additive manufacturing is increasingly reshaping digital dentistry by enabling the chairside fabrication of definitive restorations within a fully digital workflow. The novel DFAB system (RD Printing, Italy) is an innovative chairside 3D printer based on a proprietary laser technology known as Tilted Stereolithography (TSLA), which differs from conventional DLP systems. Tilted Stereolithography employs a laser source and a uniquely inclined printing plane to enhance printing precision, surface quality, and mechanical performance of composite restorations. This technology allows the production of definitive single crowns and small fixed prostheses directly in the dental office within a single appointment. This presentation will describe the complete clinical workflow – from intraoral scanning and CAD design to chairside 3D printing, post-processing, and final delivery – highlighting accuracy, marginal adaptation, material properties, and clinical indications. The integration of laser-based additive manufacturing at chairside represents a significant step toward efficient, high-performance, and patient-centered restorative dentistry.
