摘要： A sealing attachment for connection of a static mixer to a dual chamber cartridge dispenser containing separate, different materials. There is an outer sleeve (12) with a rotatable connection to a center plug (14) positioned inside a collar (20) of the outer sleeve (12). The center plug includes hollow male prongs (32, 34) which engage outlets (108, 110) of the cartridge(s) (100) to form a seal therewith. The outer sleeve has tabs (24, 26) on the outside of the collar (20) for engagement with locking arms (126, 128) on a discharge end of the cartridge(s) (100) when the hollow male prongs (32, 34) are placed within the outlets (108, 110) of the cartridge(s) (100).

摘要： A device (10) for dispensing a predetermined amount of fluid material from chambers within a cartridge (148). This device includes a housing, a trigger pivotably connected to the housing (12) and a plunger (18) having teeth (108) on a top side thereof entering the housing and passing through an upper part of the trigger (46). A ratchet (110) is attached to the upper part of the trigger and engaged between the plunger teeth. When force is applied to the trigger, the ratchet is pushed forward. When the trigger is released, the ratchet moves backward causing the plunger to move with the ratchet. The plunger moves backward a short distance until the force applied by the ratchet is overcome through frictional engagement between the plunger and a frictional brake (104, 106) mounted on the housing, at that point the ratchet slides over the next tooth behind it on top of the plunger.

摘要： The modulus of elasticity and yield strength of a rigid core rod (24) are set within predetermined limits as to limit the elastic deformation and prevent plastic deformation of a dental tray (20) during multiple impression taking, bite registration, and subsequent handling. The tray (20) is formed with a frame (22) which provides a positive recovery force when it is flexed. The cross section of the core rod (24) may be optimized to further limit deflection in a predetermined plane. Various preferred materials including non-woven spun bonded filaments are selected for supporting impression material (30) on the tray (20) while minimizing the likelihood of obstructing a patient's teeth during full occlusion.

摘要： A dispensing and mixing apparatus (10) for simultaneously dispensing from a cartridge (12) into a static mixing element (14) components which harden when mixed. The components exit the cartridge into the mixing element without intermixing as the components leave the cartridge. The initial intermixing of the components takes place within the mixing element. The cartridge is reusable since the components do not become mixed and harden as they come out of the cartridge. The chambers (22, 24) in the cartridge are of semi-cylindrical configuration and have rounded corners (36, 38, 40, 42). Ribs (100) can be provided on the cartridge for stiffening the cartridge from deforming under extrusion.

摘要： An impression tray (10) for making impressions of the upper and lower teeth. The tray includes a mouthpiece (13) and a handle (12). The mouthpiece (13) includes an outer wall (14), inner wall (16) and a base (18) connected between the walls (14, 16) at a bottom thereof. The walls (14, 16) each have vertical slits (54, 68) spaced along their length. Each slit (54, 68) has a shoulder (60, 73) therein providing an interlock for the impression material displaced therethrough. The base (18) includes ribs (88) on its top, each rib (88) extending between the walls (14, 16) and alternating with the slits (54, 68) on the walls. Between each adjacent pair of ribs (88) are two holes (90) extending through the base (18). The base (18) is also attached, on its bottom, to a platform structure. The platform structure provides a flat surface for the tray and forms reservoirs (102) around the base holes (90). The combination of the ribs (88) and the platform structure provides a rigid structure, thereby producing an impression with a minimal possibility of deformation.
