Proposed Method for the Standardized Measurement of Marginal Bone Height on Periapical Radiographs with the Brånemark System®
Bibliographic record
Abstract
BACKGROUND: Strict criteria have been stipulated to evaluate success and failure of dental implants. Periapical radiographs are considered an important means of evaluation. However, there is a lack of standardized and reproducible readily available methods to carry this out. PURPOSE: The purpose of this article is to describe the manufacturing and clinical use of a simple device that enables the clinician to take parallel and reproducible periapical radiographs of dental implants. MATERIALS AND METHODS: Commercially available implant prosthetic components and film holder for periapical radiographs were modified and used clinically. RESULTS: Clinically, the device works effectively and does not require significantly more time. CONCLUSIONS: The described device is a simple appliance with an uncomplicated method to overcome problems with taking parallel and reproducible radiographs of dental implants, which is especially important when measuring marginal bone height.

How this classification was reachedexpand
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.
