Ridge Mapping Double Caliper

The Ridge Mapping Double Caliper is constructed from German-grade surgical stainless steel with a passivated finish that prevents corrosion through repeated sterilization cycles. The instrument measures approximately 16.5 cm (6.5 inches) overall and features a scissor-action double-arm design with two circular finger rings at the base for controlled, one-handed operation. Inward-angled pointed tips at the working end converge symmetrically when the arms close. A fan-shaped sector scale plate, mounted centrally between the crossed arms, displays graduated markings from 0 to 35 mm for direct measurement reading.

The Bone Ridge Mapping Caliper 6.5″ Ring Style incorporates a ratchet-step locking mechanism within the ring handles, securing the jaw opening once bone contact is made and preventing measurement drift. This scissor-action dental caliper withstands full autoclave sterilization at 134°C and is compatible with ultrasonic cleaning and chemical disinfection. The passivated surface resists oxidation, and the instrument passes boil, performance, and shape quality-control tests before dispatch, confirming reliable reuse across multiple procedures.

Oral surgeons and implantologists use the Ridge Mapping Double Caliper during pre-implant alveolar ridge assessment. Under local anesthesia, the surgeon presses the inward-angled tips through mucosal tissue at the planned implant site until they contact the cortical bone bilaterally. The Bone Caliper Ridge Mapping Implant then delivers a direct buccolingual ridge width reading on the sector scale, enabling accurate implant diameter selection and crestal bone volume confirmation before surgical flap elevation or osteotomy begins.

The instruments that define a surgical practice are the ones that work without compromise, session after session. Leader Surgical understands this, which is why every caliper in its catalogue meets verified material, locking, and sterilization standards that implant teams can depend on from the first case to the thousandth.

What is the primary purpose of this caliper?
It is used to measure the buccolingual width and height of the alveolar bone ridge before reflecting a surgical flap. This helps determine if there is sufficient bone volume for a dental implant or if bone grafting is needed.
