An endosseous implant is described as osseointegrated when it is immobile in function. Objective measures of stability testing have been described. The Periotest is a commercially available device that is used for this purpose. This study was designed to measure stability of endosseous implants placed in the mandible. Implants were placed in the mandibular canine or first premolar area to support an overdenture prosthesis. Stability was evaluated through the use of a Periotest device at the time of implant placement and following one year of functional loading. Implant designs were either a screw-shaped titanium alloy or a hydroxyapatite-coated cylinder. A total of 54 implants were placed, 37 were titanium screw-shaped implants, while the remaining 17 were hydroxyapatite cylinders. Initial measurements of stability showed no difference due to implant type. Following one year of functional loading, titanium screw-shaped implants were more stable than hydroxyapatite implants (P < 0.05). The difference in implant rigidity following a period of functional loading may be an indication of a difference in osseointegration between the two implants used in this study.
当骨内种植体在功能上固定不动时，就被描述为骨整合。已经描述了稳定性测试的客观测量方法。Periotest是一种用于此目的的商用设备。本研究旨在测量植入下颌骨的骨内种植体的稳定性。种植体植入下颌尖牙或第一前磨牙区域以支持覆盖义齿修复体。在种植体植入时以及功能负载一年后，使用Periotest设备评估稳定性。种植体设计为螺旋形钛合金或羟基磷灰石涂层圆柱体。总共植入了54颗种植体，其中37颗是钛螺旋形种植体，其余17颗是羟基磷灰石圆柱体。稳定性的初始测量结果显示，不同种植体类型之间没有差异。在功能负载一年后，钛螺旋形种植体比羟基磷灰石种植体更稳定（P < 0.05）。一段时间的功能负载后种植体刚度的差异可能表明本研究中使用的两种种植体在骨整合方面存在差异。
