To evaluate radiographic bone level (RxBL) at dental implants and its associated factors in Spain.
This cross-sectional study was performed by a network of sentinel dentists from regions of Spain. RxBL was defined as the distance from the implant shoulder to the first clearly visible contact between the implant surface and the bone. Radiographic measurements were performed by two trained and experienced periodontists. Implant and patient data were also collected. Descriptive, bivariate, discriminative and multivariate analyses were done.
A total of 49 sentinel dentists provided data 275 patients. Mean RxBL from 474 implants (5-13 years) was 1.87 mm (range: 0.00-13.17 mm). Statistically significant associations between RxBL and clinical output variables (bleeding on probing, oedema, plaque, probing depth, suppuration, keratinized tissue) were found. In the multiple regression analysis, statistically significant associations for RxBL were found for smoking habit, implant diameter, years of follow-up and type of prosthesis (p < 0.01).
Peri-implant RxBL ranged from 0 to 13.17 mm. It was significantly associated with clinical output variables and with some potentially predictor variables, at patient- (smoking >10 cigarettes/day) and implant- (diameter, years of follow-up, Toronto bridge) levels.
评估西班牙种植牙的放射骨水平（RxBL）及其相关因素。
本横断面研究由来自西班牙各地区的哨点牙医网络进行。RxBL 定义为从种植体肩到种植体表面与骨之间首次清晰可见接触之间的距离。放射学测量由两名经过培训和经验丰富的牙周病学家进行。还收集了种植体和患者的数据。进行了描述性、双变量、判别和多变量分析。
共有 49 名哨点牙医提供了 275 名患者的数据。474 个种植体（5-13 年）的平均 RxBL 为 1.87mm（范围：0.00-13.17mm）。RxBL 与临床输出变量（探诊出血、水肿、菌斑、探诊深度、溢脓、角化组织）之间存在统计学显著关联。在多元回归分析中，吸烟习惯、种植体直径、随访年限和义齿类型与 RxBL 有统计学显著关联（p<0.01）。
种植体周围的 RxBL 范围为 0 至 13.17mm。它与临床输出变量以及患者（吸烟>10 支/天）和种植体（直径、随访年限、多伦多桥）水平的一些潜在预测变量显著相关。
