Dentists are often faced with extensively resorbed mandibular ridges with shallow buccal vestibule and high insertion of the mentalis muscle in relation to the crest of the ridge, causing the displacement of the prosthesis. Vestibuloplasty techniques aim at eliminating the muscle insertions, reposition the mucosa, and increase the area chapeável, giving more stability to the prosthesis. Among the techniques to deepen the vestibule are submucosal vestibuloplasties by secondary epithelialization and with mucosal and skin grafts. We will discuss vestibuloplasty by secondary epithelialization with emphasis on the so-called modified Kazanjian technique. This technique provides an appropriate result and does not require hospitalization, additional surgery at the donor, or prolonged periods without the use of prosthesis.
牙医常常面临下颌牙槽嵴广泛吸收、颊侧前庭浅以及颏肌相对于牙槽嵴嵴顶高位附着的情况,这会导致义齿移位。前庭成形术旨在消除肌肉附着、重新定位黏膜并增加可塑形区域,从而使义齿更稳定。在加深前庭的技术中,有通过二期上皮化以及使用黏膜和皮肤移植的黏膜下前庭成形术。我们将讨论通过二期上皮化进行的前庭成形术,重点是所谓的改良卡赞吉安技术。该技术能产生合适的效果,且无需住院、在供区进行额外手术或长时间不使用义齿。
