摘要:
A dental post removal device having a hollow tubular structure having a sidewall and distal and proximal open ends, an engaging feature positioned on insides of the sidewalls, and a fulcrum positioned on the hollow tubular structure adapted for pulling the hollow tubular structure and a dental post captured therein. The engaging features can be a series of openings formed through the sidewall of the hollow tubular structure, and/or the inner wall surfaces of the sidewall that is one of at least scored, textured, dimpled, coated with a high adhesion material or other type of surface preparation chemical, and/or internally threaded. The tubular structure is of generally constant outside diameter. The inner walls can either be of constant inner diameter, or can have an inner diameter that narrows from the distal end to the proximal end either continuously, or in discrete steps of increasingly smaller diameter.
