The health of teeth is crucial to human quality of life. With the advancement of science and technology, dental restoration technology has also undergone tremendous changes. From early natural materials to modern high-tech synthetic materials, the development of dental restorations is not only the advancement of medical technology, but also reflects mankind's continuous pursuit of aesthetics and health.
The history of tooth restoration can be traced back to ancient times. In Italy, there is evidence that ancient humans used pitch to repair teeth as early as 13,000 years ago, while in Neolithic Slovenia, ancient people used beeswax to fill cracks in their teeth.
In ancient Roman documents, such as Pliny's "Natural History", there are mentions of tooth filling materials, showing the history of human exploration of tooth restoration.
To effectively repair a tooth, you first need to prepare it. This process typically involves using rotating handheld dental tools and drills to remove cavities and damaged parts of the tooth. At this stage, if a permanent restoration is not immediately possible, temporary restorative materials may be used to protect the tooth.
The choice of restorative material depends on the extent and location of the tooth decay. These materials can include gold, amalgam, resin dental materials, glass ionomer cement, etc.
Direct restoration technology involves placing a soft filling material into a prepared tooth for reconstruction. After these materials are cured, the function of the tooth is restored. This repair can usually be completed in one visit, and the type of material used depends on the severity of the tooth decay.
Indirect restoration is to make a restoration outside the mouth first and then fix it on the tooth. These restorations may be crowns, bridges, or veneers, etc., and are often made by a dental technician based on the dentist's impression.
With the rapid development of 3D printing and CAD/CAM technology, dentists can now quickly produce high-definition dental restorations in the clinic, thereby shortening patient visit time.
Dental restorations use a wide variety of materials, including traditional amalgam, resin materials that have become popular in recent years, and glass ionomer cement.
Amalgam is a time-honored restorative material that remains somewhat popular for its durability and availability, although its safety has been questioned by some.
Resin filling materials are also widely used because they are similar in color to teeth and can better meet patients’ aesthetic needs.
Today, many patients prefer to use resin materials in order to achieve higher aesthetic results, but these materials are still not as durable as metal materials.
The future of dental restorative technology will be accompanied by the continued development of new materials and the accelerated application of digital technology. Whether it is the selection of materials or the improvement of repair technology, focusing on improving patient comfort and results seems to be the main trend in the future.
With the increasing demand for beauty and health, we can’t help but ask: How will dental restoration technology be innovated again in the future to meet the changing needs of patients?
