In materials science, research focuses on membrane biocompatibility, development of bio/smart composite aligners, and direct printing technology for clear aligners. Although mainstream materials are generally safe, some still harbor cytotoxic risks. Smart composite materials offer novel strategies for monitoring and preventing enamel demineralization and bacterial biofilm formation by integrating sensors or incorporating antimicrobial agents. Directly printed aligner technology demonstrates significant potential due to its customizability and high precision. Regarding clinical efficacy, evidence indicates that clear aligners achieve comparable results with fixed appliances for mild-to-moderate malocclusions, though their efficiency and effectiveness are slightly inferior in complex extraction cases. Regarding specific tooth movement control, arch expansion primarily relies on crown inclination, yielding results below design expectations; molar distalization achievement is also limited. Studies refute the notion that a specific \"bite-ramp effect\" causes mandibular counterclockwise rotation. For skeletal class Ⅱ malocclusions in children, clear aligners combined with functional orthodontic modules show promising applications, though evidence levels require further enhancement. Regarding oral health impacts, multiple studies confirm that clear aligners effectively reduce enamel demineralization risk, decrease plaque accumulation, and improve periodontal health compared with fixed appliances. In summary, clear aligner technology has advanced toward great precision, efficiency, and personalization. However, clinicians must recognize its tool-like nature.

In the preoperative phase, by acquiring the patient's digital information model and integrating data with the assistance of an artificial intelligence-driven planning system, personalized design of implant positions and prosthesis morphologies can be achieved, thereby realizing accurate functional and aesthetic matching. During the surgical procedure, the adoption of static implant guides, dynamic navigation systems, or implant robotic systems can effectively enhance surgical precision and minimize patient trauma to the greatest extent. In the immediate and final restoration phases, digital impression technology based on intraoral and extraoral scanning systems enables accurate acquisition of information regarding implants, as well as hard and soft tissues related to edentulous jaw implantation. Among these technologies, the application of AI-assisted algorithms and modified intraoral scan bodies can further improve patient comfort and chairside work efficiency.

For complex edentulous cases, such as pterygoid implant placement, implant robotic systems based on digital three-dimensional modeling enable high-precision implantation with intraoperative dynamic calibration, thereby improving prosthetic predictability. Although challenges remain in data interoperability and standardization of clinical protocols, the integration of unified data standards, comprehensive intelligent platforms, and standardized workflows may facilitate the standardized and intelligent application of digital technologies in edentulous implant rehabilitation.

It has transformed from a simple tool for tooth alignment to an essential component of multidisciplinary oral treatment. It has shown significant advantages in the orthodontic treatment of periodontal disease, the orthodontic treatment of temporomandibular joint disorder (TMD), integrated approaches with dental implant restoration, and the combined treatment of orthodontics and orthognathic surgery. The objective of orthodontic treatment for periodontal disease is to enhance health and stability. Commencement of clear aligner treatment is advised after the management of periodontal inflammation. The principle of applying gentle and gradual force must be adhered to. The extent of tooth movement should be reduced. The coverage of the aligner should be minimized. The time between aligner replacements should be extended. The objective of orthodontic treatment for TMD is to achieve occlusal-joint coordination, eliminate occlusal trauma, stabilize joint function, align the teeth, and improve occlusion. Clear aligner intervention is only suitable for stable TMD. Emphasis is placed on collaborative multidisciplinary management. Informed consent for orthodontic treatment of patients with TMD is crucial. The goal of combined orthodontic and restorative treatment is to integrate space and aesthetics. The digital design of clear aligners can optimize spacing, expand the area for dental implants, intrude over-erupted opposing teeth, upright tilted abutment teeth, ensure optimal gingival distance and mesiodistal diameter for dental implants, and when combined with smile design, it can significantly improve the pink and white aesthetic score. Precise orthodontic-surgical coordination is achieved for the combined treatment of severe skeletal malocclusion via orthodontics and orthognathic surgery. The digital design of clear aligners facilitates the alignment of the upper and lower dental arches more effectively compared with fixed orthodontic treatment. It effectively reduces chairside operation time and significantly improves treatment efficiency. At present, the application of clear aligners in multidisciplinary fields remains limited, and high-quality studies are lacking.
