4.Molar relation changed from class II to class I relationship;Anterior overjet and overbite are normal;Good occlusal intercuspation is also achieved.
矫治完成后均达到理想的侧貌外形,牙关系由II类改正为I类关系,前牙覆覆盖正常,尖窝关系良好。
5.Using a simple semi-fixed lingual arch combined with the edgewise technology to correct 8 cases with linguoclination or buccoclination of the mandibular molars.
对8例下颌牙颊向或舌向倾斜错位的患者,采用简易半固定舌弓配合方丝弓矫治技术在矫治初期进行矫治。
6.Results indicate interestingly that the double bond of GMA polymerized with polystyryl carbanion and the molar ratio of epoxy end group and polystyrene oligomer can be adjusted.
7.Tooth implants were generated from pig third molar tooth bud cells seeded onto polyglycolide (PGA) and polyglycolide-colactide (PLGA) scaffolds, and grown for 4 weeks in the omenta of adult rat hosts.
8.Firstly, p-methylacetophenone was obtained in the presence of alchlor as the catalyst, and the optimum condition was 4:1:2 in molar ratio for toluene, acetic anhydride and alchlor with yield of 86.2%.
