In cases of severe horizontal atrophy, implant placement requires bone reconstruction procedures. The aim of this randomized controlled trial is to compare the outcomes of bone augmentation with simultaneous implant placement using the shell technique to the outcomes of guided bone regeneration (GBR) in cases of severely horizontal bone atrophy. This study was designed as a monocentric, parallel-group, randomized controlled trial with a six-month follow-up. Among the primary outcomes of this study, peri-implant bone regeneration and peri-implant bone defect closure were selected. Forty-four patients were recruited and equally divided between two groups. In the GRB group, a horizontal regeneration of 2.31 ± 0.23 mm was observed opposed to a horizontal regeneration of 2.36 ± 0.17 mm in the shell group ( = 0.87). A volumetric increase was observed in both groups, with an increase of 0.30 ± 0.12 cm in the GBR group and an increase of 0.39 ± 0.09 cm in the shell group, highlighting a significant difference between the two groups ( = 0.02) In conclusion, bone augmentation with simultaneous implant placement using the shell technique or guided bone regeneration in horizontal bone atrophy are both predictable therapeutic options.
在严重水平骨萎缩的病例中，种植体植入需要进行骨重建手术。本随机对照试验的目的是比较在严重水平骨萎缩病例中，使用外壳技术同时进行种植体植入的骨增量结果与引导骨再生（GBR）的结果。本研究设计为单中心、平行组、随机对照试验，随访6个月。在本研究的主要结果中，选择了种植体周围骨再生和种植体周围骨缺损闭合情况。招募了44名患者，并将其平均分为两组。在GBR组中，观察到水平骨再生为2.31±0.23毫米，而外壳组为2.36±0.17毫米（P=0.87）。两组均观察到体积增加，GBR组增加0.30±0.12立方厘米，外壳组增加0.39±0.09立方厘米，突出显示两组之间存在显著差异（P=0.02）。总之，在水平骨萎缩中使用外壳技术同时进行种植体植入的骨增量或引导骨再生都是可预测的治疗选择。
