ObjectivesTo investigate long‐term alveolar ridge bone changes in patients treated with the split‐crest technique (SCT) with simultaneous implant placement.Materials and MethodsAlveolar ridge width (ARW) was measured with a caliper immediately before (ARW1) and after SCT (ARW2) with a caliper. Existing CBCT scans taken at least 5 years postoperatively were used to assess the healed ARW (ARWF), buccal bone thickness (BBT), and lingual/palatal bone thickness (L/PBT) at 0, 3, and 5 mm apically from implant platform level (IPL). The distance between IPL and buccal bone crest (IPL‐BBC) was also measured. Findings were compared with Wilcoxon and Student's t tests (p < .05).ResultsRecords of thirty patients with 85 implants were included. Eleven patients (31 implants) presented CBCT scans taken in two separate occasions, resulting in 116 measurements. Tomographic follow‐up ranged from 5 to 18 years (11.5 ± 4.18 years). Mean ARW increased from 3.2 ± 0.6 to 6.6 ± 0.48 mm after SCT, but significantly reduced overtime to 4.46 ± 0.83 mm (ARWF) (p < .0001). Mean BBT was 0.5 ± 0.9, 1.3 ± 0.9, and 2.0 ± 1.2 mm, while mean L/PBT was 0.9 ± 0.7, 1.6 ± 0.9, and 2.1 ± 1.0 mm at 0, 3, and 5 mm from IPL, respectively. IPL‐BBC distance varied up to 8.7 mm (1.4 ± 2.0 mm), with 56/116 measurements (51/85 implants) showing IPL‐BBC = 0 mm.ConclusionAlthough SCT with simultaneous implant placement can predictably increase ARW postoperatively, ARW tended to significantly reduce over time, due to reductions in BBT and L/PBT, especially coronally. Nonetheless, 60% of the implants still presented some buccal bone at IPL.

接受劈裂嵴技术同时植入植入物治疗的患者牙槽嵴骨变化:一项回顾性纵向观察研究



目的探讨接受劈裂嵴技术 (SCT) 同时植入种植体治疗的患者的长期牙槽嵴骨变化。材料和方法在紧接 (ARW1) 之前和之后用卡尺测量牙槽嵴宽度 (ARW)。术后至少 5 年采集的现有 CBCT 扫描用于评估种植体平台水平 (IPL) 顶端 0 、 3 和 5 mm 处的愈合 ARW (ARWF) 、颊骨厚度 (BBT) 和舌/腭骨厚度 (L/PBT)。还测量了 IPL 与颊骨嵴 (IPL-BBC) 之间的距离。将结果与 Wilcoxon 和 Student 的 t 检验 (p < .05) 进行比较。结果纳入 30 例患者 85 个种植体的记录。11 名患者 (31 名植入物) 在两个不同的场合进行了 CBCT 扫描,共进行了 116 次测量。断层扫描随访时间为 5 至 18 年 (11.5 ± 4.18 年)。SCT 后平均 ARW 从 3.2 ± 0.6 增加到 6.6 ± 0.48 mm,但随着时间的推移显着降低至 4.46 ± 0.83 mm (ARWF) (p < .0001)。平均 BBT 分别为 0.5 ± 0.9、1.3 ± 0.9 和 2.0 ± 1.2 mm,而平均 L/PBT 分别为 0.9 ± 0.7、1.6 ± 0.9 和 2.1 ± 1.0 mm,距离 IPL 0、3 和 5 mm。IPL-BBC 距离高达 8.7 毫米(1.4 ± 2.0 毫米),56/116 次测量(51/85 个植入物)显示 IPL-BBC = 0 mm.结论尽管 SCT 同时植入种植体可以预测术后 ARW 增加,但由于 BBT 和 L/PBT 的降低,ARW 往往会随着时间的推移而显着降低,尤其是冠状位。尽管如此,60% 的植入物在 IPL 时仍然出现一些颊骨。
