本试验设计将2.0×2.0×4.0mm长力体磁体外包一层厚0.5mm金属钛,制成3.0×3.0×5.0mm长方体钛衣磁体,置于犬拔牙创内,恢复牙槽嵴外形,牙龈缝合。两周后检查:拔牙创完全愈合,拔牙创部位牙槽嵴丰满,拍牙片示:钛衣磁体周围无骨质吸收及感染。三月后拍牙X片示:钛衣磁体与颌骨融合。前后测磁力强度无明显变化。一年后拍片示钛衣磁体与骨融合生长,测磁力强度稍减弱。本试验共做4只家犬8个牙位,均获得成功,无一牙失败。结论为:①拔牙创内有钛金属支架利于牙龈爬行生长。②磁体产生的磁场对骨生长愈合有促进作用。③颌骨保持原有高度和宽度,有利于义齿修复并有足够的支承力。④义齿基托内放置相应磁体增加其固位,有利于义齿功能。
In this experiment, a 2.0 × 2.0 × 4.0mm long-body magnet was outsourced with a layer of 0.5mm titanium metal to form a 3.0 × 3.0 × 5.0mm cuboid titanium-coated magnet placed in a canine tooth to restore the shape of the alveolar ridge. The gums Stitched. Two weeks after the examination: Tooth extraction completely healed, tooth extraction site alveolar ridge fullness, filming teeth show: titanium clothing around the magnet without bone absorption and infection. March after filming X film shows: titanium clothing magnet fusion with the jaw. Before and after testing the magnetic strength no significant change. A year after the film shows the titanium magnet and bone fusion growth, the measured magnetic intensity slightly weakened. This experiment a total of 4 dogs 8 teeth, were successful, without a tooth failure. The conclusions are as follows: (1) There is a titanium stent in the tooth extraction to promote the growth of the gums. ② magnetic field generated by the magnet to promote bone growth and healing. ③ keep the original height and width of the jaw, which is conducive to the prosthesis repair and have sufficient support force. ④ Denture base placed within the appropriate magnets to increase its retention, is conducive to denture function.
