METHODS: When esthetic crown lengthening is performed as an adjunct to restorative therapy, the surgical approach must be determined by the anticipated position of the restorative margins. The removal of sufficient bone to achieve the desired clinical crown length and preserve the supracrestal gingival tissue dimensions is facilitated by the use of a surgical guide fabricated according to the design of the restorations. A staged approach allows sequencing the provisional restoration to minimize unesthetic sequelae during the healing period. Inadequate bone resection and/or alteration of the soft tissue dimensions results in delayed healing, leading to coronal gingival rebound and biologic width impingement.
CONCLUSIONS: The identification and preservation of appropriate restorative and biologic landmarks is essential for success in pre-prosthetic esthetic crown lengthening treatment. A staged approach improves the esthetic management during the postsurgical healing and maturation period.
CONCLUSIONS: A restorative driven classification system for sequencing and staging adjunctive esthetic crown lengthening procedures is presented. Technical guidelines to enhance gingival margin predictability are suggested, accompanied by relevant evidence. In addition, wound healing timelines following gingival and osseous resection are provided.
方法:当审美牙冠延长术作为修复治疗的辅助手段时,手术入路必须由修复边缘的预期位置决定.通过使用根据修复体的设计制造的手术引导件,促进了足够的骨的移除以实现期望的临床牙冠长度并保持上牙龈组织尺寸。分阶段的方法可以对临时修复进行排序,以最大程度地减少愈合期间的不美观后遗症。不充分的骨切除和/或软组织尺寸的改变导致延迟愈合。导致冠状牙龈回弹和生物宽度撞击。
结论:确定和保留适当的修复性和生物学标志对于修复前美学牙冠延长治疗的成功至关重要。分阶段方法可改善术后愈合和成熟期的美学管理。
结论:提出了一种恢复性驱动分类系统,用于排序和分期辅助美学牙冠延长程序。提出了提高牙龈边缘可预测性的技术指南,并附有相关证据。此外,提供了牙龈和骨切除后的伤口愈合时间表。
