In Office Soft Relines

By Lee Ann Brady on 08.06.13Category: Dental Materials, Restorative Dentistry

Removable has not always been my favorite of the procedures that I offer to my patients. In light of that over the years I am always looking for better techniques and better materials that improve the predictability and ease of removable prosthodontics. Recently I have found a new material and technique for in office soft relines. Sofreliner Tough by Tokuyama does not have any odor or taste. It sets in 5 minutes intraorally and does not require mixing. The instant I realized it wad mixed and dispensed with a gun I knew it would be an improvement over the materials that come as a powder and liquid.

The material is an addition silicone and comes in two viscosities depending on your preference.  Soft reline material is designed to be no more than 2mm in thickness, but not less than 1mm. If you have more than 2mm of space the denture or partial should have a hard reline. If the patient prefers a soft liner, you can then add a soft reline over the new hard acrylic reline for comfort. The denture base should be relieved to allow 1-2mm of space, and the borders beveled out onto the labial side of the flange several millimeters.

As with all relines, adding adequate material to the inside and borders of the denture is imperative. Once the prosthesis is seated the patient should be asked to close into ICP,and visual verification that the occlusion looks appropriate. While the material sets border molding should be accomplished to make sure that the denture will not be displaced during speaking, chewing or swallowing, Once the material has reached a full set the denture or partial is removed, the excess liner material removed and the borders smoothed. In addition to being patient friendly, easy to handle and quick to set this material is easy to clean off the areas of the denture you did not reline. The kit comes with special burs that trim and feather the reline material beautifully.

    Hi Lee! Do you use this for relining immediate dentures over the 3-6 months that the tissues are remodelling? Its cheaper than doing a lab reline for the patient? Thank you!!

      Sharon,

      Yes this is how I do the relines following immediate dentures. they have two types of spft, and they have a hard material that you can use once the ridges are more stable.

    Lee Ann,

    Have you noticed if the inoffice hard reline material that you mention can damage the gingiva due to an exothermic reaction?

    Thanks,

    Lemond

      Lemond,

      There is some heat generated, but this material seems to produce less than a more traditional powder liquid acrylic, and I have not noticed anything more than a transient redness.
