Abstract
The present invention relates to a method for retaining a passive post and reinforcing endodontically treated teeth by coating a passive metal post with silicone and then with a resin coating, forming a post canal in a cavity, irrigating the post canal with a solution of Ethylene Diamine Tetracetic Acid, irrigating the post canal with Sodium Hypochloride, evacuating the post canal with a high vacuum suction tip, mixing and adding a cement comprising Bis-GMA and TEGDMA to the post canal, distributing the cement with a Lentulo spiral, inserting the silicoated metal post into the post canal, and holding the metal post under pressure until the cement sets. The invention also relates to vacuum apparatus for evacuating a post channel and dentinal tubules of moisture and to create an empty intertubular zone. The vacuum apparatus includes a vacuum suction tip having an outer diameter less than the inner diameter of the post channel and a high vacuum source connected to the vacuum tip. The invention further relates to a hexagonal shaped, parallel sided passive post. Surprisingly, the body of the remaining tooth structure is reinforced up to 30.3% and retention values similar to active posts are achieved by the method according to the claimed invention.
