Peri‐implant radiographic bone level and associated factors in Spain
Bibliographic record
Abstract
OBJECTIVES: To evaluate radiographic bone level (RxBL) at dental implants and its associated factors in Spain. MATERIAL AND METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
