种植修复是恢复牙列缺损和缺失的重要手段,但需要植入区的牙槽骨骨量相对充分,以容纳有足够长度和直径,且有植入方向和深度要求的种植体。后牙区是咬力的主要承受区,牙齿缺失后,下颌骨向下向外吸收,使得剩余牙槽嵴宽度在1年内可减少约25%,再加上下颌神经管的存在,给下后牙的种植 Implant repair is an important means of restoring the defect and loss of dentition. However, the alveolar bone in the implanted area needs to be relatively adequate in bone mass to accommodate implants of sufficient length and diameter, with implant orientation and depth requirements. Posterior teeth area is the main bearing area of ​​bite force, the loss of teeth, the mandible down outward absorption, making the remaining alveolar ridge width can be reduced by about 25% within 1 year, coupled with the presence of mandibular neural tube, to the next Tooth cultivation
