Abstract:
The objective of this study was to evaluate the clinical and radiographic behavior of a novel triangular neck implant configuration in partially edentulous patients. Sixteen patients with a mean age of 58.3 years, were rehabilitated with 25 implants inserted in the healed sites of the maxilla and mandible; implant diameter was Ø3.3 and 3.9 mm. Clinical and radiographic measurements were first performed at prosthesis delivery that served as baseline; they were further evaluated after a mean period of 15.6 months. The interproximal peri-implant bone levels were the primary outcome; the mesial and distal data were recorded and a mean value was calculated. Secondary outcomes included peri-implant probing depth (PPD) and bleeding on probing (BoP). The paired t-test was used to compare the radiographic and clinical outcomes between baseline and follow-up. The mean bone levels at the mesial and distal aspects at baseline were 0.45 (0.47) and 0.57 (0.69), respectively; at follow-up they were 0.59 (0.42) and 0.78 (0.59), respectively. The differences were not statistically significant. Similarly, no significant differences were found for the clinical parameters. Within the limitations of the present study, it could be concluded that this new triangular neck bone level implant macro-design was used successfully to treat partially edentulous patients. Larger controlled clinical studies are warranted to confirm the present radiographic and clinical findings.
摘要:
这项研究的目的是评估新型三角颈植入物配置在部分缺牙患者中的临床和影像学行为。16名患者平均年龄58.3岁,用25个植入物插入上颌骨和下颌骨的愈合部位进行修复;植入物直径为Ø3.3和3.9mm。临床和影像学测量首先在作为基线的假体递送时进行;它们在平均15.6个月后进一步评估。种植体周围骨水平是主要结果;记录近端和远端数据并计算平均值。次要结果包括种植体周围探查深度(PPD)和探查出血(BoP)。使用配对t检验比较基线和随访之间的影像学和临床结果。基线时内侧和远端的平均骨水平分别为0.45(0.47)和0.57(0.69),分别为0.59(0.42)和0.78(0.59),分别。差异无统计学意义。同样,临床参数无显著差异.在本研究的局限性内,可以得出结论,这种新的三角颈骨水平植入物宏观设计已成功用于治疗部分缺牙的患者。需要进行较大的对照临床研究以确认目前的影像学和临床发现。
