DENTAL DEVICE FOR RIDGE PRESERVATION AND PROMOTION OF JAW BONE REGENERATION IN AN EXTRACTION SITE

The invention relates to a dental device (1) for ridge preservation around the socket (2) of an extracted tooth and for promoting jaw bone regeneration inside the socket (2) of the extracted tooth, the dental device (1) comprising: a screw (3) which is entirely made of a biodegradable material to eliminate the need for a removal surgery, wherein the screw (3) is adapted for tight fixation within the jaw bone (4) in the socket (2) to prevent micromovements during bone-tissue regeneration, wherein the screw (2) has a length such that its top is, in the inserted state, flush with the alveolar ridge (5) around the socket (2) to promote full bone regeneration inside the socket (2), and wherein the screw (3) has a hollow (6) and pores (7), wherein the diameters of the pore (7) is substantially equal to or larger than 20 micrometers. 本发明涉及一种牙科设备(1)，用于在拔掉的牙齿的牙槽窝(2)周围保留牙槽嵴并促进拔掉的牙齿的牙槽窝(2)内的颌骨再生，牙科设备(1)包括：螺钉(3)，所述螺钉完全由可生物降解材料制成，以消除移除手术的需要，其中螺钉(3)适于牢固固定在牙槽窝(2)中的颌骨(4)内，以防止骨组织再生期间的微运动，其中螺钉(2)的长度使得其顶部在插入状态下与牙槽窝(2)周围的牙槽嵴(5)齐
