Title:
DENTAL GINGIVA EXPANDER HAVING IMPROVED OPERATION CONVENIENCE
Document Type and Number:
WIPO Patent Application WO/2016/052860
Kind Code:
A1
Abstract:
The present invention relates to a dental gingiva expander and, more particularly, to a gingiva expander surrounded with a silicone shell, hydrogel being bonded to both sides of the gingiva expander in the shape of a polygonal post or an elliptical post, which increases the area of contact with the alveolar bone and the gingiva, or in the shape of a streamline, which facilitates insertion into the gingiva using a narrow portion on one side thereof. The gingiva expander is advantageous in that, since the hydrogel is manufactured in the shape of a polygonal post, an elliptical post, or a streamline, the area contact between the hydrogel and the alveolar bone is increased, during insertion beneath the periosteum after gingiva incision, thereby increasing the rate of successful seating; the volume before swelling is decreased, compared with hydrogel included in conventional gingiva expanders, thereby facilitating insertion beneath the gingiva and improving the convenience in operation; and the reduced area of incision quickens recovery after operation.
