Some clinically obvious phenomena are difficult to explain using this model system, for example, the phenomenon traditionally referred to as the "row-boat effect", where uprighting of the canines excessively tipped into an extraction site results in protraction of the molars and "anchorage loss".

一些临床上明显的现象是难以解释利用该模型系统，例如，传统的现象称为"行船效应"，在扶正的犬齿过分倒进萃取结果冗长的网站的臼齿和"锚固损失"。

The patient has a radiolucent lesion below the molar teeth in the right mandible.

Ex2：病人在右下颌的大臼齿，有一放射透过性的病变。

The radiolucent around the implant was found in dental CT. Probing depth was around 6-7 mm. We tried to solve the problem with open debridement.

当对侧需要植牙拍摄牙科电脑断层时才发现右上第一大臼齿植体周围有radiolucent的现象，临床检查除近远心有6-7mm的探测深度外并无任何不适。

Gum disease can affect the first and second molars and the bone surrounding the tooth, as well as the impacted wisdom tooth.

牙龈疾病可能会影响第一和第二大臼齿和骨周围的牙齿，以及作为影响智齿冠。

Using stereomicroscope, we observed the fracture line direction and location as well as the angle between the fracture line and the attrite plane. The data was compiled into statistics and analyzed. The results revealed that most of the vertical root fractures occurred in teeth with severe attrite crown and flat root. Numerous bucco-lingual oriented fractures occurred in the mesial root of molars, and we found three non-endodontically treated cases with mesio-distal oriented fractures in the palatal roots.

结果发现，两组的垂直牙根断裂均好发於牙冠严重磨耗（77.4-88.2%）且扁平的牙根（61.8-75.8%）上，以大臼齿的近心牙根发生率最高（64-85.7%），多为颊舌侧走向（91.2-91.9%），且於未根管治疗组别亦发现三例腭侧根断裂，走向为较宽的近远心方向，显示牙根断裂会沿著牙根较宽的方向发生；同时，未经根管治疗而产生垂直牙根断裂的牙齿具有根叉位置较低的现象（61.8%），牙根於比例上有较短小的特徵。
