上颌骨半切术是一种对功能及容貌造成极大毁损的外科手术,术后遗留的口鼻腔穿通给患者造成极大痛苦。而传统的修复方法对此类问题的解决并不令人满意。同时,传统义齿常由于固位及稳定问题需时常调整。为此,学者们进行了多方努力。如用带颅骨的颞肌瓣及带肋骨的肌皮瓣恢复上颌骨的解剖结构等。1993年,Tideman等人开展了一种新的上颌骨半切术后的功能重建术,并与本文作者合作对患者进行种植义齿修复。其方法如下: 第一步,取患者上、下颌模型上(牙合)架。在模型上划出切除范围,修整模型,制作钛网状支架,以暂基托上的义齿代替将失牙,并在将放种植体位置的假牙上钻孔,以便标记模型。钛网状支架前分开一小窗,以便放入自体髂骨颗粒。下颌之对(牙合)牙上作丙烯酸树脂夹板以帮助钛网状支架于术中获得精确的定位。第二步,手术切除半侧上颌骨并即刻用钛网状支架插入两层带蒂颞肌瓣中,用钛钉固定支架于颧弓,健侧牙槽嵴及腭突之点,通过支架前份小窗填入自体髂骨颗粒,随后用钛
Maxillofacial resection is a surgical and operation of the great damage caused by surgery, postoperative left or right nose and mouth piercing caused great suffering to patients. The traditional method of repair to solve such problems is not satisfactory. At the same time, traditional dentures often need to be adjusted from time to time due to retention and stability issues. To this end, scholars have conducted various efforts. Such as the use of temporal skull flap with ribs and myocutaneous muscle flap to restore the anatomy of the maxillary. In 1993, Tideman et al. Performed a new functional reconstruction of the maxillary hemisection and collaborated with the authors in implant prosthesis repair. The method is as follows: The first step, take the patient, mandibular model (occlusal) frame. Cut out the model, trim the model, make a titanium mesh stent, replace the denture with the denture on the temporary base, and drill the denture at the position of the implant to mark the model. Titanium mesh stent separated by a small window in order to put the iliac bone particles. Mandibular (occlusal) teeth made of acrylic splint to help titanium mesh stent in the surgery to obtain accurate positioning. The second step, the surgical excision of the maxilla and the immediate use of titanium mesh stent inserted into the two temporal pedicle pedicle, with titanium nail bracket in the zygomatic arch, contralateral alveolar crest and the point of the palate, through the stent A small window filled with autologous iliac particles, followed by titanium
