To achieve long-term success of dental implants, evaluation of the dimensions of the resorbing alveolar process must be accurate because an implant should be surrounded by at least 1 mm of bone. Estimating the thickness of bone is more difficult because the mucosal contour can mask the actual dimension of the residual ridge. With ultrasound, it is possible to analyze and visualize the diameter of maxillary or mandibular residual ridges. Data obtained from ultrasound measurement of residual ridges were compared with the data from ridge mapping with the Wilson bone caliper and the Spoerlein caliper. The ultrasound measurement produced nearly the same data at all measurement points as ridge mapping. Ultrasound also provides exact information about the location of the mental foramen and the maxillary sinus. By using all three methods the initial stage of implant treatment can be planned.
为实现牙种植体的长期成功，对吸收中的牙槽突尺寸进行准确评估至关重要，因为种植体周围至少应有1毫米的骨组织。估计骨厚度更为困难，因为黏膜轮廓可能会掩盖剩余牙槽嵴的实际尺寸。借助超声，可以分析并可视化上颌或下颌剩余牙槽嵴的直径。将超声测量剩余牙槽嵴获得的数据与使用威尔逊骨卡尺和施波尔林卡尺进行牙槽嵴测绘得到的数据进行比较。超声测量在所有测量点产生的数据与牙槽嵴测绘的数据几乎相同。超声还能提供关于颏孔和上颌窦位置的确切信息。通过使用这三种方法，可以规划种植治疗的初始阶段。
