背景：本研究的目的是提出并验证一种新的基于软硬组织参数的上颌前牙拔出窝分类系统。方法：以25名受试者(男15名，女10名；年龄18~51岁；平均年龄32.4岁)为研究对象，对新的分类系统进行验证。两位独立的外科医生根据建议的分类推荐了一种治疗方法。这些建议在手术时得到了证实。采用加权Cohen‘s kappa法计算观察者间可信度。结果：观察者间符合率为96%，加权Cohen‘s K值为0.94。这表明拟议的分类系统具有很高的可靠性。当新开发的分类被用于推荐治疗时，没有种植体周围软组织被归类为缺陷。总体而言，80%的牙槽窝根据软组织参数被分级为适当的(P
Background: The aim of this study was to present and validate a new classification system for the maxillary anterior extraction socket based upon soft and hard tissue parameters.Methods: Twenty-five maxillary anterior teeth from 25 subjects (15 men and 10 women; aged 18 to 51 years; mean age = 32.4 years) were used to validate the new proposed classification system. Two independent surgeons recommended a treatment approach based upon the classification proposed. These suggestions were verified at the time of surgery. Weighted Cohen's kappa Was used to calculate interobserver reliability. Statistical analysis was performed using the paired t, Kolmagorov-Smimov, and marginal homogeneity tests.Results: Interobserver agreement and weighted Cohen's K were 96% and 0.94, respectively. This indicated a high reliability for the proposed classification system. No peri-implant soft tissues were classified as deficient when the newly developed classification was used to recommend treatment. Overall, 80% of sockets were graded as adequate based on soft tissue parameters (P
