Castroviejo Round Caliper

Castroviejo Round Caliper

The Castroviejo Round Caliper is manufactured from German-grade surgical stainless steel with a passivated satin finish that actively resists corrosion under repeated sterilization. The instrument spans 18 cm in overall length with two crossed straight shafts joined at a central ball-joint pivot. Its defining structural feature is the fully rounded, teardrop-shaped oval loop bone caliper head, the most elongated loop design within the Castroviejo Fig. series forming a smooth closed working end. A curved V-shaped base carries the graduated 0–40 mm scale etched in 1 mm increments.

A knurled thumb-screw on the lateral shaft locks jaw separation firmly once the target measurement is obtained, eliminating positional drift before the reading is recorded. This Rounded Castroviejo Caliper tolerates full autoclave sterilization at 134°C and is compatible with ultrasonic cleaning and chemical disinfection protocols. The passivated finish guards against oxidation between sterilization cycles, and standard boil, performance, and shape quality-control tests are completed before dispatch, confirming reliable reusability across procedures.

Oral surgeons and implantologists use the Castroviejo Round Caliper during dental implant pre-surgical bone assessment. After mucoperiosteal flap reflection, the surgeon places the oval loop ends across the exposed alveolar crest. This dental implant measurement caliper delivers a direct buccolingual bone width reading on the graduated base, guiding the surgeon in confirming available crestal bone volume and selecting the correct implant diameter before osteotomy preparation begins.

There are instruments that merely measure, and then there are instruments that surgical teams reach for without hesitation. Leader Surgical stocks this caliper because it earns that second category: built to German material standards, verified through quality testing, and designed to deliver consistent readings across every implant case it supports.

What is the difference between a “Round” and a “Standard” Castroviejo Caliper?
Handle Style: The “Round” refers to the ergonomic round body style. While standard calipers often have flat, pen-style handles, the rounded handle provides a more substantial grip, helps distribute pressure evenly across the palm, and reduces hand fatigue during extended use.
