The Castroviejo Round Caliper is a precise dental instrument primarily used for measuring distances and sizes during various dental procedures, such as ridge mapping. Here's a breakdown of the key features of the 17cm Ridge Mapping Castroviejo Round Caliper with a 0-40mm Scale:

1. Length: The caliper measures 17 cm in length, which is a common size for tools used in delicate dental procedures.

2. Round Tips: The caliper has round tips that allow for precise, gentle measurement without damaging delicate tissues, which is especially useful in ridge mapping to assess the available bone ridge width.

3. Scale (0-40mm): The scale is typically calibrated from 0 to 40 mm, providing a range suitable for measuring anatomical structures, such as bone width, and other important features during dental assessments.

4. Material: Typically made of stainless steel, which ensures durability, resistance to corrosion, and ease of sterilization.

5. Function: Castroviejo calipers are designed for precision and are often used in procedures like implantology, oral surgery, and prosthetics, where accurate measurement is critical. Ridge mapping involves evaluating the bone structure of a patient's jaw to determine if it's suitable for dental implants, and this caliper provides precise measurements for this task.
