Evaluation and comparison of dimensional stability of four interocclusal recording materials commonly available in India-An In-Vitro Study
Bibliographic record
Abstract
An interocclusal record is a precise recording of a maxillo-mandibular position. Interocclusal recording materials are used to record the patient's maxillomandibular relationship in correct position. The dimensional stability of interocclusal recording materials is of utmost importance. But several materials are available commercially. Various studies have shown controversy over interocclusal recording material of choice. The study was conducted to evaluate and compare the dimensional stability of four commonly used interocclusal recording materials after one hour. Poly vinyl siloxane, polyether, zinc oxide eugenol and eugenol free zinc oxide were poured on a steel die of internal diameter of 3cm and the dimensional stability was measured using travelling microscope after 1hour and the data obtained were statistically analyzed. Eugenol free zinc oxide proved to be dimensionally stable with mean values of 2.487 after 1hour of time interval which was followed by polyether, polyvinyl siloxane and zinc oxide eugenol. Eugenol-free zinc-oxide paste was the most dimensionally stable interocclusal recording material as compared to polyether, polyvinyl siloxane and zinc oxide eugenol exhibiting no statistically significant difference between die scribes and those of the samples.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
