In order to provide longitudinal data for endosteal bladevent implants, a continuing study is being conducted. The present work evaluated 32 bladevent implants in 22 patients for periods of 10 years or more. Two basic patterns were observed 10 years postoperatively: 1) In 14 of 32 implants, there was clinical and radiographic evidence of health; and 2) in 18 of 32 implants, there was a radiolucency 2 to 3 mm square around the neck and shoulder of the implants, sulcular depths capable of being probed and evidence of bleeding on probing. These results indicate that bladevent endosteal implants can be maintained in the mouth for periods of 10 years, although bony breakdown will be seen in approximately 50% of the implants.
为了提供骨内叶状开口种植体的纵向数据，一项持续研究正在进行中。目前的研究评估了22例患者的32枚叶状开口种植体，观察时间长达10年或更长时间。术后10年观察到两种基本模式：1）32枚种植体中的14枚，有临床和影像学健康证据；2）32枚种植体中的18枚，种植体颈部和肩部周围有2至3平方毫米的透射区，能探测到龈沟深度且探诊有出血迹象。这些结果表明，叶状开口骨内种植体可在口腔内保留10年，尽管约50%的种植体会出现骨质吸收。
