Application of lithium disilicate in dentistry

Lithium disilicate (Li2Si2O5) has a wide range of applications in the dental field, the following is a detailed analysis of its application:

First, dental repair materials

Lithium disilicate glass ceramics is a kind of high quality dental restorative material with good mechanical properties, semi-permeability and biocompatibility. These properties make it the material of choice for aesthetic restoration of front teeth. After heat treatment of lithium disilicate glass ceramics, a part of the glass phase in the matrix glass is transformed into a crystalline phase, which improves the strength of the material, while retaining the good semi-light transmittance of the glass phase, so that it can well simulate the luster and light transmittance of natural teeth. Therefore, lithium disilicate glass ceramics are often used in dental restorations to make all-porcelain veneers, all-porcelain crown Bridges and implant superstructures.

Second, specific application cases

Crown and bridge restoration: Lithium disilicate is widely used in the manufacture of restorations such as crowns and Bridges due to its excellent durability and aesthetics. These restorations maintain their natural beauty and functionality in the mouth.

Dental implants: In dental implants, lithium disilicate is often used for root filling in the implant system. Due to its high biocompatibility and stability, it can effectively promote the healing of the plant and the surrounding bone tissue, thereby improving the success rate and long-term effect of planting.

Orthodontic field: lithium disilicate is also widely used in the field of oral orthodontics at home and abroad, mainly used in the substrate material in the production of invisible appliances. Its good transparency and plasticity provide a high-quality substrate for the invisible appliance, making the appliance more comfortable and natural when worn.

Third, research and application prospects

The application of lithium disilicate in dental field has been studied deeply at home and abroad. For example, some studies have investigated the mechanical properties, aesthetic properties and clinical application of lithium disilicate glass ceramics in dental restorations. In addition, there are also studies to improve the performance of lithium disilicate glass ceramics by optimizing the preparation process and modifying treatment to meet different dental restoration needs.

With the continuous development of material science and dental technology, the application prospect of lithium disilicate in the dental field will be more broad. In the future, lithium disilicate materials are expected to play a greater role in improving the aesthetics, durability and biocompatibility of dental restorations, bringing better treatment results and experiences to patients.

Fourth, market and commercialization

After nearly 20 years of research abroad, Ivoclar-Vivadent's IPS series and other lithium disilicate glass ceramic products have been put on the market, and achieved good clinical results. At present, there are relatively few researches on lithium disilicate glass-ceramics in China, and there are some problems such as single preparation method, unknown crystallization mechanism and poor product performance. Therefore, the research and development of lithium disilicate glass-ceramics materials with independent intellectual property rights is of great significance for breaking through technological monopoly and barriers, promoting all-porcelain restoration applications and reducing restoration costs.

In summary, lithium disilicate has a wide range of application value and development prospects in the dental field. With the continuous progress of material science and dental technology, it is believed that lithium disilicate materials will play an increasingly important role in dental restoration in the future.
