Plumbers Tape & Screw Access Holes

By Lee Ann Brady on 07.08.13Category: Dental Marketing, Implant Dentistry, Restorative Dentistry

One of the challenges I run into with implant dentistry is managing the crew access holes. Now we all hope to fill them once and then never have to get to the head of the screw again, but this is dentistry after all and that would be unrealistic. In the last 6 months I have partnered with two patients to replace implant supported hybrid prostheses, and had to remove and replace the old restoration at every appointment managing the access holes.

Classically I was taught to use a cotton pellet to cover the screw and then fill the top of the hole above that. Placing the cotton is pretty easy, you create long hotdog shaped pieces if cotton and then condense them into the access hole. Removing them however is not so easy, Some people pack the cotton tightly and others place less, but either way we are left trying to grab on to and tease the cotton out with instruments like an explorer or endo file.

On the suggestion of the oral surgeon that I work with i have recently stopped using cotton pellets and started using plumbers tape. This white Teflon tape is available at any hardware store, and I have it in my office as I use it as a matrix when seating veneers and inlays to protect adjacent teeth and preps. I cut off an inch to an inch and a half piece of the plumbers tape. Grab one end with a cotton pliers and using the tips of the pliers pack it in over the screw access hole. It is tacky so it sticks to itself and forms a mass inside the access hole. When it is time to take it back out once you get the tip of the explorer into the end the whole piece feeds right out in an instant.

    Thank you for your blog and information you share. It is hugely valuable.
    The advice that you received is a controversial though.
    Plumber’s tape has not been designed for medical use. Many people question toxicity of Teflon itself, but in case of the tape there is considerable volume of perfluorooctanoic acid (used for Teflon synthesis). Medical grade Teflons get cleansed of it.
    It is one thing to use tape for temporary isolation of adjacent teeth and another when you leave toxin emitting matter in the abutment shaft. Coupled with non-hermetic implant-abutment it may create micro-pump of intra-shaft liquids and leads to chronic exposure.
    In my opinion heated gutta-percha would be a better option.
