Dental osteotomes are surgical instruments used primarily in dental implantology and oral surgery. They are designed to cut or reshape bone, particularly in procedures involving sinus lifts or bone grafting. The term "offset concave" refers to the specific shape and design of the osteotome, which allows for precision in certain surgical maneuvers. A 5-piece set of offset concave dental osteotomes typically includes instruments of varying diameters to suit different surgical needs. Here’s a general breakdown of what such a set might include: Key Features: Offset Design: This helps improve access to difficult-to-reach areas, such as the posterior maxilla. Concave Tip: The concave shape at the tip helps in controlled bone compaction and shaping, minimizing trauma to surrounding tissues. Material: Usually made of high-quality surgical-grade stainless steel for durability and sterilization purposes. Sizes: The set typically includes 5 osteotomes with increasing diameters (e.g., 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, and 5.0 mm). Applications: Sinus Lift Procedures: Used for elevating the sinus membrane and placing bone graft material. Bone Condensation: Helps prepare the implant site in soft bone by compacting the bone rather than removing it. Precise Bone Shaping: Ideal for reshaping and preparing the bone for dental implants.
