目的统计分析上颌骨严重萎缩无牙颌患者的鼻旁梨状孔边缘骨的厚度与鼻底牙槽骨厚度,为严重萎缩无牙颌患者上颌骨前牙区的种植提供数据支持。方法 26例严重上颌骨萎缩无牙颌患者进行计算机断层扫描(CT)的三维测量,对鼻旁梨状孔边缘骨的厚度及鼻底牙槽骨的厚度进行统计分析。结果鼻底区域的剩余牙槽骨的厚度平均值约为5.5mm,鼻底区域的剩余牙槽骨的高度平均值约为6.1mm,需要进行鼻底提升术进行骨增量。梨状孔区域的鼻旁骨在鼻底水平以上3mm与6mm水平的厚度平均值分别为4.6mm和3.6mm,可以进行骨劈开手术进行骨增量。结论严重萎缩无牙颌患者鼻旁剩余骨量满足骨劈开和鼻底提升术的要求,鼻旁骨劈开复合鼻底提升术可有效用于严重上颌骨萎缩无牙颌患者的种植体植入。
Objective To analyze and analyze the thickness of the marginal bone of the nasal piriform foramina and the thickness of the alveolar bone in the maxillary atrophic edentulous patients with maxillary atrophy, providing data support for the atrophy of maxillary anterior teeth in edentulous jaw patients. Methods Twenty-six patients with severe maxillary atrophy and edentulous jaw were measured by computerized tomography (CT). The thickness of the marginal bone of the nasal piriform hole and the thickness of the nasal alveolar bone were statistically analyzed. Results The average thickness of the remaining alveolar bone in the nasal floor area was about 5.5 mm. The average height of the remaining alveolar bone in the nasal floor area was about 6.1 mm. Nasal floor elevation was required for bone augmentation. The average thickness of the nasal parasagittal bone in the piriform hole region at the level of 3 mm and 6 mm above the level of the nasal floor is 4.6 mm and 3.6 mm, respectively. Bone splitting can be performed for bone augmentation. Conclusion The severe residual atrophy of maxillary atrophy in maxillary atrophy patients with maxillary atrophy and edentulous patients can meet the requirements of bone splitting and nasal ascending surgery.
