Compression Expander Screws Kit

Compression Expander Screws Kit

The Compression Expander Screws Kit (Article# LS9-331) contains four surgical-grade stainless steel screws seated in a compact, hinged perforated sterilization cassette. Three bone compression screws measure 2.5mm, 3.6mm, and 4.1mm in diameter, while one sinus elevation screw measures 3.5mm. Each screw features laser-etched depth markings indicating 8mm, 10mm, and 13mm penetration levels. Color-coded silicone base mounts — white, green, and blue — correspond to an engraved diameter reference chart on the cassette floor for immediate intraoperative identification.

The Bone Compression Screw Set instruments carry self-threading, tapered screw geometry that laterally displaces trabecular bone during insertion rather than removing it. All four screws are universally compatible with any 4.0mm torque wrench, ratchet wrench, or adapter regardless of brand, eliminating compatibility concerns across different surgical setups. The highly polished stainless steel construction resists surface degradation and withstands full autoclave sterilization at 134°C across repeated cycles, while the cassette’s perforated base guarantees unobstructed steam circulation around every instrument.

The Sinus Elevation Expansion Kit is used by oral and maxillofacial surgeons and implantologists during ridge expansion and sinus floor elevation procedures. The surgeon selects the appropriate compression screw diameter using the cassette’s engraved reference chart, inserts it with a 4.0mm torque wrench, and advances to the laser-marked depth to laterally condense bone walls. The 3.5mm sinus elevation screw is then used to carefully elevate the Schneiderian membrane, creating vertical bone height for posterior maxillary implant placement without lateral window entry.

Leader Surgical stands out among implant instrument suppliers for producing kits where every design decision traces directly back to surgical practicality. The engraved diameter chart, universal wrench compatibility, and laser depth markings on this kit collectively remove guesswork at every stage of the procedure, giving surgeons reliable reference points from first screw selection through final depth confirmation.

How many instruments does the Compression Expander Screws Kit contain?
The kit contains four instruments total; three bone compression screws (2.5mm, 3.6mm, and 4.1mm) and one sinus elevation screw (3.5mm), all housed in a single stainless steel sterilization cassette.
