ABSTRACT:OBJECTIVETo study the correlation between anatomic structure of the inferior alveolar nerve canal and dental implantation by measuring mandible innervation esemplarsMETHODSThe intramandibular course of mandibular canal and its dimendion were measured in 15 mandibles with teeth; the relationship between blood vessel and nerve was observed in 5 fresh samples in which the artery was filled; and then the data were analyzed by statisticsRESULTSThe mandibular canal was close to the lingual side and the inferior margin of the mandible, the mandibular canal and the 10mm underside of mandible were parallel in the region of the first and the second molars, it runned outboard to genal aperture when it was hereabout genal aperture, and the blood vessel lay above nerve in the mandibular canalCONCLUSIONIn implant operation performed according to normal anatomy, injury to inferior alveolar nerve may be avoided.

［目的］探讨下颌管的解剖结构与牙种植的关系［方法］选取15具牙列完整的成人离体下颌骨标本和5具经过动脉血管内灌注的新鲜标本，测量下颌骨在每个牙位截面上有关牙槽嵴及下颌管的相关数据，进行统计学分析［结果］牙槽嵴顶以及下方10mm宽度由前向后逐渐增宽；牙槽嵴由上向下逐渐增宽；下颌管位于下颌骨体内下方走行中偏舌侧，并近下颌骨下缘，在下颌第1，2磨牙区下颌管走行与下颌下缘成平行状，在近颏孔处转向外和向颊侧出颏孔；下颌管内血管位于下牙槽神经之上［结论］牙种植术中按正常解剖部位并且侧重颊侧骨板操作，可避免损伤下牙槽神经；如果术中下颌管内突然涌出大量新鲜血液，则提示若继续手术可能损伤下牙槽神经。

The two kinds of clefts are: unoperated isolate cleft palate and unilateral cleft lip and palate with lip only operated. Considering the effect of age on the results, The samples were divided into two age groups: mixed dentition stage and adult permanent dentition stage. The cases of these two groups of unoperated isolate cleft palate patients are 16 and 25 respectively, and those of unilateral cleft lip and palate with lip only operated are 15 all.

考虑到青春期生长发育对研究结果的影响，又分别将这两种类型的患者按年龄分成混合牙列期和成人恒牙列期两个年龄段，与相应年龄段的单纯腭裂术后患者、单侧完全性唇腭裂术后患者及非唇腭裂正常者进行比较，单纯腭裂未手术的患者混合牙列期和成人恒牙列期例数分别为16例和25例，单侧完全性唇腭裂仅修复唇裂患者混合牙列期和成人恒牙列期例数均为15例。

The using of cephalogram is limited because of the structure overlapping of the skull, jaw and teeth, for example the overlapping of the right side teeth and the left side make it difficult to distinguish the landmarks of posterior teeth.

颅颌骨牙齿之间影像的重叠使头颅定位x线片的应用受到了限制，比如牙列的重叠使后牙区的标志点难以辨认，所以对牙列的研究要借助牙〓模型。

The restoration of dentition meant not only to fill the missing teeth and increase the efficiency of mastication, but also to maintain the integrity of dentition and the health of residual teeth, especially loosen teeth that could be reserved. Bone resorption might lead to teeth mobility and the change of occlusal pattern and proximal relationship. Also, the endurant threshold to bite force decreased. Occlusal loads within the normal range to loosen teeth would lead to broken down of periodontal tissues.

Results: After 6~7 months the dentures in crowded patients were arranged neatly, the upper first molars were moved 0.31mm mesially evenly, and the upper incisors were moved 0.20mm labially evenly.

结果：成人牙列拥挤患者6～7个月后牙列排齐整平，上颌第一磨牙向近中整体前移，其冠部平均前移了0.31mm，上颌切牙冠部向唇侧平均倾斜移动约0.20mm。

The clinical characters of oligodontia concluded from this study are following:(1) There is significant difference that more teeth absent and more existent teeth anomalies in patients of oligodontia/S group than in patients of oligodontia/I group, and the peg-shaped upper lateral incisor is the most frequently affected teeth with shape anomaly.(2) Both of the two groups have no significant differences in number of teeth missing between maxilla and mandible as well as that between left and right side.(3) The distribution of teeth missing is bilateral symmetry in both groups, but the frequency of teeth lost are different: excluding the third molar, in oligodontia/I group, the lower second premolar is the most frequently congenitally missing tooth followed by the upper lateral incisor, while in oligodontia/S group, the most frequently missing teeth are mandibular canine and maxillary lateral incisor. Nevertheless, the first molars are the most stable teeth in both groups.(4) In oligodonita/I group, the mean mesiodistal dimensions of all type of existent teeth are significantly smaller than normal value. It is implied that oligodontia is not an isolated phenomenon, but is related to a complex of other dental changes.

对于口腔多个恒牙先天缺失的临床特点有以下初步结论：(1)综合征型先天缺牙患者较单纯型先天缺牙患者恒牙缺失数目更多，平均分别为23.9个和14.9个，且现存牙齿有更多的形态异常，分别为7／10例（70％）和6／22例（27.3％），其中最常见的是上颌侧切牙畸形；(2)两种类型的多个恒牙先天缺失患者的缺牙数目在上下颌及左右侧之间均无差别；(3)两种类型的多个恒牙先天缺失患者在缺失牙位上均呈对称分布，但在具体牙位上有所差异：不计第三磨牙，单纯型先天缺牙最常缺失的牙位是下颌第二双尖牙、其次为上颌侧切牙；而综合征型先天缺牙最常缺失的牙位是下颌尖牙和上颌侧切牙；无论何种情况，第一磨牙均为牙列中最稳定的牙齿；(4)在单纯型先天缺牙患者中，现存恒牙的牙冠宽度较国人正常值偏小，差异显著，提示牙齿形态与多个牙先天缺失有一定相关性。

Result: During this period the length of dental arch decreased evidently, the width enlarged remarkably and the height tended to increase slightly.
