下颌阻生第三磨牙拔除术,除高位阻生与牙冠完全萌出之外,先要在粘膜上施行切口与翻瓣,使手术区得以暴露,以便手术顺利进行。早在四十年代日本远藤的著作已提及阻生牙的切口,他是先做远中切口,位置偏向远中颊侧,长约15～17毫米,后者系水平阻生的切口长度(图1)。切开后的粘膜分成A瓣与B瓣,两瓣均须剥离。其次再做颊侧切口,即在第二磨牙的颊侧龈缘上做一个垂直切口,然后剥开整个龈瓣阻生牙拔除后将两处切口分别缝合。 Gores认为拔除未完全萌出的牙齿对 Implantation of the mandibular third molar extraction, in addition to the high resistance and crown full of eruption, the first mucosa incision and flap should be implemented so that the surgical area can be exposed for the surgery to proceed smoothly. As early as the forties in Japan Endo's work has referred to incisional implants, he is the first to do far incision, the location is far from the buccal side, about 15 to 17 mm, the latter is the level of incision length incision (figure 1). After the incision mucosa is divided into A and B flap, both must be stripped. Followed by the buccal incision, which is in the second molars buccal gingival margin made a vertical incision, and then peel the entire gingival flap impacted tooth removal after the two incisions were sutured. Gores thinks it's not enough to erode the teeth that have not completely erupted
