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 three groups were loaded and analyzed under the same loading according to the mean value of the bite force of incisors. RESULTS:(1)The maximum stress of dentin in group A was twice higher than that in group B. The maximum primary stress, minimum primary stress and maximum shear stress of group A were respectively 236.35, 228.83 and 218.05 percent of those in group B. The difference of maximum stress values of group B and group C was neglectable.(2) The maximum stress distribution of dentin in group A and group B was quite different (the stress was concentrated in labial and lingual side of the cervical dentin in group A, otherwise in group B it was concentrated in the area around the alveolar and the labial and lingual side of the dentin which was opposite to the tip of the cast metal post and core). The maximum stress distribution of dentin in group A and group B was almost the same.
结果:(1)从牙本质的应力大小来看,A组中牙本质最大应力值比B组中牙本质最大应力值增大了1倍以上(最大主应力、最小主应力和最大剪切应力A组分别是B组的236.35%、228.83%和218.05%),而B组与C组的牙本质最大应力值相差极小;(2)从牙本质的应力分布位置来看,A组与B组的牙本质最大应力分布位置相差甚远(A组主要集中在牙颈部唇舌侧肩台部的牙本质上,B组主要集中于牙槽嵴顶附近及铸造桩核尾端相对应的唇舌侧的牙本质上),而B组与C组的牙本质最大应力分布几乎在同一位置。

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。
