Best practices: Restorative complications

Rubber dam challenges
Metal clamps damage tooth structure or porcelain surfaces of crowns
Prevention and management
The use of light cured provisional material can reduce the potential of metal rubber dam clamps to cause iatrogenic damage (Liebenberg, 1995). Prior to clamp placement, a small amount of composite based material may be added to the metal prongs of the clamp. Alternatively instead of metal clamps, the use of plastic rubber dam clamps is less likely to damage tooth structure or existing restorations (Madison, Jordan, and Krell, 1986).
Placing a matrix band on the same tooth as a rubber dam clamp
Prevention and management
One of the methods to solve this complication is to open the clamp with rubber dam forceps and then place the matrix under the prongs and then release the clamp on the band, securing it during the procedure. Another method is to use a sectional matrix secured with a wedge and compound, thus avoiding the clamp entirely.
Poor adaption of rubber dam to partially erupted teeth or a short clinical crown lacking a supragingival undercut is a common challenge leading to clamp instability
Prevention and management
Ford, Ford, and Rhodes (2004) advocate the use of the split dam technique along with a caulking agent to achieve an adequate seal. Morgan and Marshall (1990) recommend that a glass ionomer cement, like Fuji Plus, may be mixed according to the manufacturerâs directions and loaded into a composite syringe. The material is syringed along the gingival margins of the tooth to be prepared to approximate normal tooth contours. A plastic instrument may be used to shape the material to create adequate facial and lingual undercuts. The material provides a circumferential surface against which the rubber dam may seal. After the procedure is completed, the glass ionomer/composite material may be removed with a large spoon excavator or curette.
Wakabayashi et al. (1986) recommend that a small amount of self-curing resin mixture be placed at the gingival margin on the reciprocal surfaces of the tooth and cured well, after which a standard clamp is set apical to the resin spots, as this will facilitate supragingival retention of a rubber dam clamp.
Class V cavity preparation and restoration complications
Lacerating gingival tissue and compromising periodontium due to poor gingival tissue management and isolation
Prevention and management
Isolation of class V cervical lesions for soft tissue displacement, moisture containment, and infection control can utilize several methods, including rubber dam isolation, placing retraction cord in the sulcus, minor gingival surgery using a radio-surgical laser, scalpel gingivectomy prior to rubber dam retainer placement, cotton roll/saliva ejector isolation, and the use of clear matrix systems for anatomical contour.
Rubber dams help prevent operative-site exposure to blood and crevicular and intraoral fluids. In order to isolate a class V lesion, the hole in the rubber dam for the tooth to be restored is positioned approximately 3 mm facial to the normal hole position, slightly larger in size, and with slightly more distance between the adjacent holes. After the dam is placed, a 212-type clamp is engaged on the lingual side of the tooth and rotated into position in the facial, while stretching the dam apically to reveal the lesion. The beak of the 212-type clamp should be positioned at approximately 1 mm apical to the anticipated preparation gingival margin of the cavity preparation. This usually requires stabilization of the retainer with thermoplastic impression compound. In apically extensive lesions, the beaks of the 212-type clamp may be modified by bending the lingal beak coronally (not apically) and rotating the 212-type clamp facially during placement, securing with one hand while the compound is added to the bow of one side until it is hard. The decision to bend the facial beak apically will lead to a more restricted access to the lesion and thus should be avoided. The teeth must be dry for the heated compound to be secure. After one side is placed, the compound is placed on the other side of the bow. A safe alternative way to use heated compound is to take the Monoject syringe and trim back the tip so you have a wider lumen. Then take green stick compound, break it up into smaller pieces, and place it into the Monoject syringe. Immerse the syringe in hot water. The compound melts and you can then inject the compound into the desired area. It is much easier and safer than messing with a flame chairside and is much easier to direct into the desired location, especially if you are using one hand, which you often are in this situation since you are using the other hand to maintain the position of the 212-type clamp. When the restoration had been completed, rubber dam forceps easily break the compound loose upon retainer removal.
