Biomedical engineering (BME) in dentistry integrates engineering principles and technologies with dental science to improve the diagnosis, treatment, and prevention of oral diseases. Many modern dental diagnostic and treatment tools have emerged directly or indirectly from biomedical engineering. Among its most important contributions are digital technologies, advanced materials, and precision equipment that enhance the quality, safety, and efficiency of dental care.
Biomaterials are essential in treating, repairing, or replacing damaged oral tissues. These include biodegradable polymers for targeted drug delivery, metals and alloys for dental implants, and ceramics and composites for restorations. Dental biomaterials are designed to withstand challenging oral conditions, including acidity, moisture, temperature changes, and repeated chewing forces. Some also possess antimicrobial properties that may reduce bacterial growth, lower the risk of secondary caries, and extend the service life of restorations. In addition to improving the appearance of restored teeth, biomaterials support oral function and patients’ overall well-being.
Dental implants are medical devices surgically placed into the jawbone to replace missing teeth and support crowns, bridges, or dentures. Tooth loss caused by injury or disease may lead to bone loss, speech difficulties, altered chewing patterns, and discomfort. Dental implants offer a durable solution that closely resembles the appearance and function of natural teeth. They can help preserve the jawbone and facial structure, restore normal chewing, support healthier food choices, and improve patients’ confidence and quality of life. However, their long-term success depends on proper clinical assessment, surgical placement, oral hygiene, and regular dental care.
Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) have also transformed restorative dentistry. These technologies allow dental professionals to digitally design and manufacture customized crowns, bridges, inlays, onlays, and veneers. In some cases, restorations can be completed within hours instead of requiring several days. Because CAD/CAM systems use digital scans, they can produce highly precise restorations with improved fit, comfort, durability, and natural appearance. They also streamline clinical workflows and reduce patients’ waiting time.
Similarly, three-dimensional (3D) printing has become a valuable tool in dentistry and orthodontics. Through additive manufacturing, dental professionals can rapidly produce customized models, surgical guides, aligners, denture frameworks, and other dental appliances without relying entirely on conventional molds. Its high level of precision can result in better-fitting devices and more individualized treatment. On-demand production may also reduce material waste, shorten manufacturing time, and minimize the need to maintain large inventories, contributing to more economical and sustainable dental practice.
Tissue engineering represents another promising field in dental regeneration. It aims to repair or replace damaged structures—including dentin, dental pulp, periodontal ligament, and alveolar bone—through the coordinated use of cells, scaffolds, biomaterials, and bioactive molecules. Researchers are also exploring approaches for regenerating enamel and more complex dental structures. In the future, these developments may allow clinicians to restore damaged tissues more naturally, preserve oral function, and provide less invasive treatments with better long-term outcomes. Biomedical engineering has brought transformative changes to dentistry. Innovations in biomaterials, dental implants, CAD/CAM systems, 3D printing, and tissue engineering have improved the precision, efficiency, and quality of dental treatment while enhancing patient comfort and clinical outcomes. As biomedical engineering continues to advance, it is expected to expand treatment possibilities, make dental services more personalized and accessible, and further improve oral health and patients’ quality of life.
