ABSTRACT:
A device to place osseous implant substances into interdental alveolar bone defects. This device is an osseous implant syringe with an axial lumen of consistent cross-section to allow movement of the granular substance through the lumen. The granular substance is moved through the lumen by use of a syringe plunger member. Barrel caps are provided to prevent spillage of the osseous implant substance when the syringe is not in use. The outlet of the syringe is sufficiently small to effectively enter alveolar bone defects. An extension nozzle member is provided for those areas that cannot be reached by the syringe barrel member alone. An outlet cap can be placed over the extension nozzle member to prevent spillage when it is not in use. Furthermore, a plunger extension lengthens the syringe plunger member to completely dispense the osseous implant substance from the extension member. A curved extension nozzle member can also be attached to the end of the syringe barrel member to reach those areas that cannot be reached with a straight barrel. A filling device is provided for fast and efficient loading of the syringe barrel members.
