Abstract

Background: Dental absences are a worldwide issue, affecting patients both socially and functionally. Implant rehabilitation is the gold standard treatment; however, prior bone reconstructions may be necessary. The Barbell Technique is a guided bone regeneration technique recommended for defects of various morphologies, allowing for vertical and horizontal unidirectional or bidirectional regeneration, that is, both on the buccal and palatal/lingual sides. The objective of this paper is to report a case of bone reconstruction in the posterior maxilla prior to implant rehabilitation, where the Barbell Technique was performed together with a sinus lift. Methods: This study consists of a case report of a 77-year-old male patient with the absence of first and second right bicuspids and a history of implant losses in the area. The initial CT scan showed horizontal and vertical alveolar atrophy, making implant placement impossible. Regeneration was performed using a sinus lift for vertical recovery and the Barbell Technique for horizontal regeneration, using xenogeneic bone covered by a collagen membrane. After 6 months, a new CT scan suggested sufficient bone volume, and two implants were guidedly placed based on digital planning. Results: Comparison of CT scans before and after the grafts showed a horizontal bone gain of 70% and a vertical gain of 33%. Six months after the reconstructive surgery, dental implants were placed, followed by the installation of individual crowns after 45 days. At the 24-month follow-up, no complications related to the implants or prostheses were observed. Conclusion: In this clinical case, for the first time in the literature, the association of the techniques allowed the regeneration of the defect, with the subsequent placement of implants in the ideal position and prosthetic rehabilitation.

杠铃技术联合鼻窦提升用于水平和垂直引导骨再生1例报告。
背景:缺牙是一个世界性的问题,影响患者的社会和功能。种植体康复是金标准治疗;然而,可能需要先进行骨重建。杠铃技术是一种引导骨再生技术,推荐用于各种形态的缺陷,允许垂直和水平单向或双向再生,即在颊侧和腭侧/舌侧。本文的目的是报告一例在种植体康复之前的后上颌骨重建,其中杠铃技术与窦提升一起进行。方法:本研究报告了一名77岁男性患者,其右侧第一和第二双尖缺失,并有种植体丢失的历史。最初的CT扫描显示水平和垂直牙槽萎缩,使种植体无法放置。采用鼻窦提升术进行垂直恢复,Barbell技术进行水平再生,使用胶原膜覆盖的异种骨。6个月后,新的CT扫描显示骨容量足够,并根据数字计划引导放置两个植入物。结果:植骨前后的CT扫描显示水平骨增重70%,垂直骨增重33%。重建手术6个月后,植入牙种植体,45天后安装单个冠。在24个月的随访中,未观察到与种植体或假体相关的并发症。结论:在这个临床病例中,这是文献中第一次,这些技术的结合使缺损再生,随后将植入物放置在理想位置并进行假肢康复。
