Investigation was performed on the effects of removing the inferior alveolar neurovascular structures on the permanent dentition and mandibular growth. Five puppies with erupted deciduous teeth had the inferior alveolar neurovascular structures removed unilaterally. When the test animals were 28 weeks old, examination revealed that the deciduous teeth on the side operated had exfoliated but permanent teeth did not replace them. On the other hand, the permanent teeth on the side not operated on replaced the exfoliated deciduous teeth. After a second period of 28 weeks, the germs of the permanent teeth on the side operated on were still buried in the mandibular bone, and the permanent teeth on the side not operated on erupted normally. Mandibular measurements demonstrated that translative and transformative growth and developmental processes were normal in both the sides operated on and the sides not operated on.
研究了去除下牙槽神经血管结构对恒牙列和下颌骨生长的影响。五只乳牙已萌出的幼犬单侧去除下牙槽神经血管结构。当实验动物28周龄时，检查发现手术侧的乳牙已脱落，但恒牙未替换它们。另一方面，未手术侧的恒牙替换了脱落的乳牙。再过28周后，手术侧恒牙胚仍埋在下颌骨中，未手术侧的恒牙正常萌出。下颌测量表明，手术侧和未手术侧的平移和转化生长发育过程均正常。
