| titleOfInvention | Preloaded Dental Dam and Gingival Contraction Method |
| abstract | Methods and apparatus for achieving cordless contraction of gingival groove tissue include dams shaped to fit on the teeth. The dam has a peripheral wall that forms a well. The peripheral wall may be transmissive or impermeable to light and is open at at least one end. The walls of the dam are prefilled with an amount of flowable shrinkage material having a high viscosity or putty density. The preloaded tooth dam is fitted to the prepared tooth so that when pressure is applied to the tooth dam, the shrinkage material is displaced under pressure and pressed into the groove so that the gingival tissue contracts from the tooth to expand the gingival groove. In one aspect of the invention, the structure of the dam allows the shrink material to be mechanically bonded or bonded to the inner surface of the dam, and allows the shrink material to move simultaneously with the dam to escape behind a clean expanded groove. In another embodiment, the cap is filled with expandable material. In another embodiment, the cap is filled with a saturated compressible porous material. |
