Final answer:
The surgical stent used as a guide for the placement of implant screws in dental implantology is typically made of clear acrylic resin. This material is chosen for its ease of fabrication, visibility, and compatibility with imaging techniques.
Step-by-step explanation:
A surgical stent is a device used in dental implantology as a guide for the accurate placement of implant screws. The material typically used for such stents is C. Clear acrylic resin. This material is chosen because it offers several benefits: it's relatively easy to fabricate, offers clear visibility during placement, and it's compatible with various imaging techniques.
Clear acrylic resin allows the surgeon to have a precise guide while positioning the implant screws, which is crucial for the success of the implant procedure. While materials like stainless steel and titanium are known for their strength and are commonly used in the implants themselves, clear acrylic resin is preferred for the stent due to its radiolucent property and ability to be easily shaped to fit the patient's anatomy.
