This report describes the efficacy of a guiding flange appliance in correcting mandibular deviation in the hemi-mandibulectomy patient and correlates the time elapsed between surgery and placement of the appliance and the extent of initial mandibular deviation to the success rate of a guiding flange appliance in correcting the deviation.
A total of 15 hemi-mandibulectomy patients participated in the study. All had various degree of mandibular shift consequent to surgery. The patients were given a guiding flange prosthesis for about 4 months, and the efficacy of the guiding flange prosthesis was calculated in terms of percentage deviation corrected after 4 months.
Time elapsed between surgery and prosthetic rehabilitation was in inverse relation to the percentage correction in mandibular deviation at 4 months (B = -7.668; p = 0.002). The less the initial deviation postsurgery, the better the correction (B = 9.798; p = 0.008).
Percentage correction of mandibular deviation is dependent on the timing of prosthetic rehabilitation. The less the initial deviation, the better the correction.
本报告描述了一种导向凸缘矫治器在纠正半侧下颌骨切除患者下颌偏斜方面的疗效,并将手术与矫治器放置之间的时间间隔以及初始下颌偏斜程度与导向凸缘矫治器纠正偏斜的成功率相关联。
共有15例半侧下颌骨切除患者参与了本研究。所有患者术后均有不同程度的下颌移位。为患者佩戴导向凸缘修复体约4个月,并根据4个月后纠正的偏斜百分比计算导向凸缘修复体的疗效。
手术与修复性康复之间的时间间隔与4个月时下颌偏斜的纠正百分比呈负相关(B = -7.668;p = 0.002)。术后初始偏斜越小,纠正效果越好(B = 9.798;p = 0.008)。
下颌偏斜的纠正百分比取决于修复性康复的时机。初始偏斜越小,纠正效果越好。
