Final Answer:
To fabricate a dental model, dental stone or dental plaster is commonly selected as the dental material.
Explanation:
Dental models, also known as study models or casts, are essential tools in dentistry for diagnosis, treatment planning, and patient education. They are used to replicate a patient's oral cavity for various purposes, such as orthodontic treatment, prosthodontics, and restorative dentistry. When selecting a material for fabricating dental models, dental professionals typically choose between dental stone and dental plaster.
Dental stone, also called gypsum or die stone, is a preferred choice for fabricating dental models due to its durability and precision. It is available in different types with varying levels of hardness, allowing for customization depending on the specific requirements of the case. Dental stone is ideal for creating detailed and accurate models, making it suitable for procedures like crown and bridge work.
Dental plaster, on the other hand, is less durable and more porous compared to dental stone. It is often used for preliminary study models and for applications where precision is not as critical. Dental plaster is more cost-effective and easier to work with, making it a suitable choice for educational purposes and initial impressions.
In summary, the selection between dental stone and dental plaster depends on the specific needs of the dental procedure and the level of accuracy required. Dental stone is the preferred choice for precise and detailed models, while dental plaster is more commonly used for less critical applications.
