Excessive alveolar bone resorption is commonly found when teeth are extracted. This is a problem in anterior part of mouth because it will result in an unaesthetic pontic on a narrow hollowed out alveolar ridge. Yet, another problem is gingival recession and root exposure in adjacent teeth which represent a therapeutic problem to the clinician.Use of acellular dermal matrix graft is an appropriate solution to obtain root coverage in areas with localized or generalized soft tissue recessions, particularly if the recessions create aesthetic concern or root sensitivity or shallow root caries lesions. This case report describes a surgical technique using acellular dermal matrix graft on a class III ridge defect and Millers grade II gingival recessions.There was a gain in both bucco-lingual and apico-coronal dimensions of the ridge, in both height and width directions, when compared to baseline and after 3 months. Recession was also covered compared to the baseline condition.
拔牙时常见牙槽骨过度吸收。这在口腔前部是个问题，因为它会导致在狭窄凹陷的牙槽嵴上出现不美观的桥体。然而，另一个问题是相邻牙齿的牙龈退缩和牙根暴露，这给临床医生带来了治疗难题。使用脱细胞真皮基质移植物是在局部或广泛性软组织退缩区域实现牙根覆盖的合适解决方案，特别是当退缩引起美观问题、牙根敏感或浅根龋病变时。本病例报告描述了一种在III类牙槽嵴缺损和Miller II级牙龈退缩上使用脱细胞真皮基质移植物的手术技术。与基线相比以及在3个月后，牙槽嵴在颊舌向和根尖 - 冠向尺寸上，在高度和宽度方向上均有增加。与基线情况相比，退缩也得到了覆盖。
