With the continuous development of science and technology, biomaterials are more and more widely used in the medical field, especially in dental care, such as dental restoration, dental cosmetology, dental implantation, etc. Biomaterials can mimic the structure and function of natural tooth tissue, have good biocompatibility and biodegradability, and can effectively replace traditional dental materials, improve the best effect and the quality of life of patients.
Learn about dental biomedical materials
Dental biomedical materials are currently mainly used to repair, replace, reconstruct or enhance the function and structure of teeth and oral tissues, with good biocompatibility, mechanical properties and durability, and can interact with the oral environment to achieve better results.
Dental biomedical materials can be divided into the following types according to their function.
Filling materials are used to repair tooth decay and chips, such as resin composites, glass ionic cement and amalgam.
Artificial tooth materials are used to make full dentures and partial dentures, common ceramics, metal alloys, etc.
Bone repair materials are used to enhance the stability and volume of alveolar bone and repair bone tissue defects, such as autologous bone blocks, bone substitute materials and bioactive membranes.
Catheter materials are used in root canals**, including root canal filling materials (e.g., calcium silicate, glass ionic cement) and apical filling materials (e.g., amalgam, sodium stearate), etc.
Anchorage tensile materials are used to hold and support teeth, such as dental glue, wire, elastic bands, and support materials.
Soft tissue repair materials are used to repair gum and soft tissue injuries, such as gum repair materials, articulation agents, and artificial soft palates.
The development of dental biomedical materials
The application of dental biomedical materials can be traced back to ancient times, and in the past few decades, with the progress of science and technology and the increase of clinical needs, significant progress has been made in the research and development and application of dental biomedical materials.
Use of Early Materials In ancient times, people used natural materials such as ivory, bone, and metal for dental restoration. In the late 19th and early 20th centuries, amalgam began to be widely used as a filling material, but it had problems such as toxicity and poor aesthetics.
The introduction of synthetic materials In the middle of the 20th century, synthetic materials such as resin composite materials began to be used in the field of dental restoration, which has good biocompatibility and aesthetics, and gradually replaced the use of amalgam.
Biologically active materials In the late 20th century, researchers began to explore biologically active dental materials. At this stage, a breakthrough has been made in the application of zirconia ceramic materials in dental implant technologyCalcium and phosphorus bone cement is also used for bone defect repair and implantation to promote bone tissue regeneration.
Diversification and improvement of biomaterials With the advancement of science and technology, the types and properties of dental biomedical materials continue to develop and improve. For example, the application of all-ceramic materials has been widely promoted in the field of dental restorations and dental implants, and its white appearance and excellent biocompatibility make it an ideal restorative material. In terms of bone regeneration, important breakthroughs have also been made in the research of bioactive bone substitutes and growth factors.
Research on biomimetic materials and nanomaterials In recent years, the research of biomimetic materials and nanomaterials has gradually attracted attention. By mimicking the structure and function of natural organisms, researchers have developed a variety of dental biomedical materials with excellent properties. At the same time, the application of nanotechnology has further improved the mechanical properties, biocompatibility and bioactivity of materials.
Market development for dental biomedical materials
In recent years, the global dental biomaterials market has grown rapidly. Among them, the field of dental implants is the "main battlefield" of dental biomaterials, and the global implant material market accounts for about half of the entire dental materials market.
In recent years, with the increase of public attention to self-health and the increase of oral and dental consumption budgets, China's oral and dental industry has developed rapidly, and the scale of the dental implant market has been growing. According to the "Research and Development Strategy Evaluation Report on the Operation Status of China's Dental Implant Market (2023-2030)", the market size of dental implants in China in 2021 will increase from 8900 million yuan increased to 40700 million yuan, and it is expected to reach 5.5 billion yuan in 2022.
From the perspective of material type, resin composite materials have gradually replaced traditional metal alloy materials in the field of caries repair and cosmetic restorationCeramic and all-ceramic prosthetic materials are also evolving and refining to provide patients with better aesthetic outcomes and biocompatibility.
In addition, dental bone restoration materials (bone meal) and oral prosthetic membranes used in dental implant surgery and maxillofacial restoration surgery have also developed rapidly in recent years. The role of bone repair materials in surgery is to fill the bone mass and repair bone loss, and oral prosthetic membranes are usually used in combination with the former for superficial repair of soft tissues in the mouth.
With the upgrading of consumption, the rapid expansion of the domestic oral market, there are a large number of unmet medical needs, and the market size of dental biomedical materials such as dental implants will maintain rapid growth. The use of dental biomedical materials can reduce the discomfort and pain of patients in the process, and improve the efficiency and accuracy of dental restoration, but some advanced dental biomaterials are still relatively expensive and may affect patient acceptance. It is believed that in the future, with the continuous efforts of domestic brands in material science, surface treatment technology, brand channel construction, etc., more high-quality products will be promoted to enter the market and better meet the needs of patients.
