Clinical evaluations of a new porous-surfaced implant concept (Endopore) in a large population of fully and partially edentulous patients are reported, and a technique of spreading buccal and lingual plates with osteotomes to place these implants in proximity to the sinus of the posterior maxilla is described. Three-dimensional, interconnecting pores on this implant's bone interface surface give a great surface area for bone engagement. When the maxilla is prepared by this spreading procedure, these implants can be successfully placed in areas having limited available bone. Our success rates are 97.0% for implants stabilizing a mandibular overdenture and 94.8% for implants placed in partially edentulous patients. Many times, sinus lift or other augmentation procedures can be avoided in the maxilla and mandible, allowing for less patient morbidity and for an implant reconstruction that is more affordable for the patient.
报告了一种新型多孔表面种植体概念（Endopore）在大量全口和部分无牙患者中的临床评估情况，并描述了一种用骨凿撑开颊侧和舌侧板以便将这些种植体放置在上颌后部窦附近的技术。该种植体骨界面表面的三维互连孔隙为骨结合提供了很大的表面积。当通过这种撑开程序对上颌进行制备时，这些种植体能够成功植入可用骨有限的区域。我们在下颌覆盖义齿种植体的成功率为97.0%，在部分无牙患者中种植体的成功率为94.8%。很多时候，在上颌和下颌可以避免进行窦提升或其他增骨程序，从而降低患者的发病率，并使患者能够负担得起种植体修复。
