Flowable wings

Several clinal procedures need rubber dam placements. It is not easy; especially in the situation where the Root canal treatment has been done on a tooth prepared with vertical perparation or feather edge. It is most difficult when the target is in good isolaltion without soft tissue damage.

This tecnique suggests that flowable composite can be used to place temporary wings, (which is good to stabilise the rubber dam) and can be easily removed after treatment.

The temporary wings are also helpful when fixing the Rubber dam in restorative dentistry.

Technique step by step:

Fig. 1

Fig 1.- Clean the tooth by Air polishing with glycine powder for 5 seconds, subsequent use the sonic instrument to reactivate the dentine. If there is a build up reactivate the composite too.

Fig. 2

Fig 2.- By sonic instrument (diamond coated insert), obtain a spot of reactivated dentin. Verities flow (Kerr) (the flowable used in this technique) is self adhering, it needs “fresh” tissue.

Fig 3.- You need a spot of tissue (dentin and/or composite) reactivated to allow the self adhering process.

Fig. 4

Fig 4.- Air dry the tooth’s surface, and place the Vertise flow on the tooth, letting it flow on the gengiva. Wait for 5 to 10 seconds to achieve the specific adhesion required. Light cure for 40 seconds. (If you wait 20 seconds as constructor says, the self adhering process will be completed and you will need to cut with a bur the wings…)

Fig 5.- Fit the dam between gengiva and Flowable wings. This is possible because of gengiva resilience.

Fig 14.- It is good to drive the dam in the good position also using wings on the close teeth.

Fig. 15

Fig 15.- In Edentulous areas rubber dam tends to rise. In this case a wing placed in the mesial 36 can be useful to mantain the Rubber dam in a proper position.
