GC Lisipress use in Dentistry
GC LiSi Press is a product by GC, a well-known dental products manufacturer. GC LiSi Press is a type of dental ceramic material, specifically a high-strength lithium disilicate glass-ceramic, designed for use in pressable dental restorations. It is utilised in the fabrication of dental prosthetics like crowns, inlays, onlays, and veneers. Here's how it is used in dentistry:
1. Material Properties:
- GC LiSi Press is known for its excellent strength and durability, making it suitable for long-lasting dental restorations.
- It offers high esthetics due to its optical properties, closely mimicking the natural translucency and color of tooth enamel.
2. Pressable Ceramic Technique:
- Dental restorations made from GC LiSi Press are created using a pressable ceramic technique. In this process, a wax model of the restoration is first made based on an impression or digital scan of the patient's teeth.
- The wax model is then used to create a mold into which the lithium disilicate glass-ceramic material is pressed under high heat and pressure.
- The pressing process allows for precise replication of the mold, ensuring a highly accurate and well-fitting restoration.
3. Application in Dental Restorations:
- Once pressed and cooled, the restoration (such as a crown or veneer) is removed from the mold and undergoes additional processing like trimming, staining, glazing, and polishing to achieve the desired esthetic and functional characteristics.
- The finished restoration is then checked for fit and function in the patient's mouth and cemented onto the prepared tooth or teeth.
4. Advantages of Lisi Press:
- GC LiSi Press restorations are favoured for their strength, which is particularly beneficial for back teeth that endure higher biting forces.
- The material's aesthetic qualities make it an excellent choice for front teeth restorations where appearance is critical.
- It also has predictable shade matching and a low reaction layer, which simplifies the post-pressing cleaning process.
5. Considerations:
- As with all dental materials, the success of GC LiSi Press restorations depends on proper case selection, skilled preparation by the dentist, and meticulous laboratory work.
GC LiSi Press represents a combination of strength and esthetics in the field of dental ceramics, reflecting the ongoing advancements in dental materials technology. For patients requiring dental restorations, it offers a durable and visually appealing option.
