Articulator Plane Line (Hinge Type) is a mechanical dental device designed to simulate the movement of the mandible in relation to the maxilla, ensuring accurate positioning of dental casts. It helps in diagnosing occlusal discrepancies, fabricating dental prosthetics, and performing restorative procedures. The hinge-type design allows easy opening and closing movements, replicating the jaw's natural motion. This articulator ensures precision in recording and transferring maxillomandibular relationships, aiding in the creation of accurate dental restorations. Lightweight, durable, and easy to handle, it is an essential tool for dental laboratories and clinics, facilitating high-quality treatment planning and prosthetic fabrication.
