对于松动牙齿(松牙)一般均采用结扎、覆盖树脂等方式予以固定,可概称之为外固定。牙根管一骨内种植术则为内固定,其特点是用组织相容性良好的金属种植体(制成符合需要的桩)通过根管植入牙槽骨内,与口腔隔绝,既不借助邻牙支持而增加邻牙负担,而牙面又无任何附加物,可保持牙齿天然的外形美观和自洁作用。种植体植入骨内有一定长度(10mm左右,视固定需要而定),起到延长牙根的作用,并由于调整了牙齿的牙槽内臂(有牙槽骨支持的牙根部分)与牙槽外臂(牙冠加上失去骨支持的牙根部分)的比例,从而使松牙得以稳固。
For loose teeth (loose teeth) are generally used ligation, covering resin, etc. to be fixed, can be described as external fixation. Endodontic canal implantation is internal fixation, which is characterized by good tissue compatibility of metal implants (made to meet the needs of the pile) through the root canal implantation of alveolar bone, isolated from the mouth, neither Orthodontic support with the increase of adjacent teeth burden, while the tooth surface and without any additional materials, to maintain the natural appearance of the teeth beautiful and self-cleaning role. The implants are implanted into the bone for a certain length (about 10 mm, depending on the need of fixation), which serves to prolong the effect of the root. Due to the fact that the internal alveolar arm (the root part with alveolar bone support) The ratio of the outer arm (crown plus the root of the bone that has lost bone support) allows the callus to stabilize.
