Immediately or delayed sinus augmentation after pseudocyst removal: A randomized trial
Bibliographic record
Abstract
PURPOSE: To compare clinical and histological outcomes of sinus augmentation performed immediately or 3 months after pseudocyst removal through a prospective randomized controlled study. MATERIALS AND METHODS: In total, 33 sinus augmentation procedures were performed in 31 patients. Augmentation was performed either immediately after pseudocyst removal (one-stage intervention) or after 3 months (two-stage intervention). Six months postoperatively, bone specimens were harvested, and histomorphometric analysis was performed as primary outcome. Data were recorded and evaluated for implant survival rates, marginal bone resorption, complication rate, and patient-centered outcomes (visual analogue scale [VAS]). RESULTS: There were no baseline differences between groups or dropouts. Twelve biopsies obtained for histomorphometric analysis showed that delayed sinus augmentation, when compared to immediated led to a 1.1% increased mineralized bone ratio (95% confidence interval [CI]: -15.9 to 13.7). Graft leakage and acute sinusitis occurred in one patient in the one-stage group, none in the two-stage group. No pseudocyst recurrence was observed until the end of 1-year follow-up. Median VAS scores for overall acceptance were significantly increase of 1.4 (95% CI: 0.3-2.56) in immediate group. The degree of post-operative discomfort was not significantly different, although an increase of VAS (0.52, 95% CI: -0.32 to 1.37) was observed in delay group. CONCLUSIONS: Both procedures of sinus augmentation immediately and 3 months after pseudocyst removal could obtain comparable histological outcomes and had low complication rates. Patients who underwent the one-stage procedure had a short treatment course and high satisfaction rates, but this procedure is technically challenging to perform. This clinical trial was not registered prior to participant recruitment and randomization. The clinical trial registration number is ChiCTR2200063121.

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.
