Tissue dilation during multiple cast restorative techniques.
The advantages and disadvantages of three tissue dilation methods are discussed. There are distinct, identifiable advantages in selecting electrosurgery as the method, since the disadvantages to each method are essentially equal. Electrode use and type are recommended for tissue dilation for the anterior and posterior areas of the mouth. The fully rectified surgical current is suggested since it provides a clean excision of the tissue and controls hemorrhage with a thin layer of coagulum. Illustrations demonstrate electrosurgical techniques with specific electrodes for both anterior teeth and posterior teeth. The margins for full coverage preparation can be finished to the crest of the tissue and a subgingival tissue trough established to the desired depth. This provides a space to refine the preparation margins to the desired sulcular depth prior to making the elastic impression. A number of clinical examples demonstrate effective and safe electrosurgical tissue dilation. Several cases illustrate the combination of tissue recontouring along with tissue dilation. Discipline application of electrosurgery for tissue removal is safe and provides excellent results. This benefits both the patient and the dentist.
