牙种植体受到不同程度的咀嚼负荷。种植体性能与骨-种植体界面处的载荷传递密切相关，在该界面处，骨质量将高度可变。已知骨的类型和结构会影响其承载能力，并且已经证明，较差的骨质量与较高的失败率相关。到目前为止，骨分类仅提供粗略的主观方法用于术前评估，这可能被证明是不可靠的。使用Sinplant（TM）软件（哥伦比亚科学公司，哥伦比亚，MD，USA）证明，可以建立基于Houndsfield量表的骨密度客观量表，并且骨密度值与主观质量评分之间（P=0.002）以及骨密度评分与口腔区域之间（P
Dental implants are subject to masticatory loads of varying magnitude. Implant performance is closely related to load transmission at the bone-to-implant interface where bone quality will be highly variable. The type and architecture of bone is known to influence its load bearing capacity and it has been demonstrated that poorer quality bone is associated with higher failure rate. To date, bone classifications have only provide rough subjective methods for pre-operative assessment, which can prove unreliable. The results of an extensive analysis of computerized tomography scans using Simplant(TM) software (Columbia Scientific Inc., Columbia, MD, USA) demonstrate that an objective scale of bone density based on the Houndsfield scale, can be established and that there is a strong correlation between bone density value and subjective quality score (P=0.002) as well as between the bone density score and the region of the mouth (P
