The research aims were to find out further intraosseous mandible organization indications and to structure it systematically.

Material and methods

: in our research 400 mandibles were used: for the intraosseous examinations in total 300 mandibles of persons aged 20–65 were used. For all corpses cephalic index was measured. Segmentation of the mandibles were made by Jigley saw between medial root of the first molar at one side and central and second incisor of the opposite one. After that segments were stained with Schiff's reagent with following preparation. Dry preparations (n = 100) were used in exploration of mental foramen macroanatomy.

Results

: mental foramen cavity depth was divided into three types: low, n = 33 (depth 269 ± 081 mm), medium, n = 36 (depth 358 ± 092 mm) and deep, n = 31 (depth 417 ± 036 mm); transverse size of the cavity is 3109 ± 041 mm and longitudinal size is 397 ± 055 mm. According to the mandible anterior intraosseous organization research it is possible to make a mental nerve intraosseous canal types systematization: semi-oval; straight; s-shaped type, formed by two opposite and transient bends. The S-shaped type (49%) is more common in persons with a dolichocephalic skull type, especially (57.55%) in mesocephalic type and semi-oval (66.36%) in brachycephalic type.

Conclusion

: nerve in the eponymous mental foramen, (which we would like to call a cavity), is branched into two large branches: the extraosseous branch, which innervates the soft tissues (such as Rr. mentales, Rr. labiales and Rr. gingivales), and the intraosseous branch, which runs from the mental foramen to the symphysis, from the latter branch to the first premolar, to the canine and to the incisors.

下颌骨前区的结构特征。

研究的目的是找出进一步的骨内下颌骨组织适应症并对其进行系统构建。

材料与方法

：在我们的研究中使用了 400 个下颌骨：对于 20-65 岁人群的 300 个下颌骨进行骨内检查。测量所有尸体的头指数。下颌骨的分割是通过 Jigley 锯在一侧第一磨牙的内侧根与对侧的中切牙和第二切牙之间进行的。之后，片段用希夫试剂染色，制备如下。干制剂 (n = 100) 用于探索颏孔大体解剖。

结果

：颏孔深度分为三种：低，n=33（深度269±081mm），中，n=36（深度358±092mm）和深，n=31（深度417±036mm）；腔体横向尺寸为3109±041mm，纵向尺寸为397±055mm。根据下颌骨前骨内组织的研究，可以使颏神经骨内管类型系统化：半椭圆形；直的; S 形类型，由两个相对的瞬态弯曲形成。S型（49%）多见于长头颅型，尤其是中头型（57.55%）和短头型的半椭圆型（66.36%）。

结论

：同名的颏孔中的神经（我们想称之为腔），分为两个大分支：骨外分支，支配软组织（如颏骨、唇缘和牙龈）和骨内分支，从颏孔到联合，从后一个分支到第一前磨牙，到犬齿和门牙。
