Immediate implant placement combined with maxillary sinus floor elevation utilizing the transalveolar approach and nonsubmerged healing for failing teeth in the maxillary molar area: A randomized controlled trial clinical study with one‐year follow‐up
Bibliographic record
Abstract
BACKGROUND: In previous studies, immediate implant placement in molar sites has been widely applied. PURPOSE: To study the clinical effect and feasibility of immediate implant placement combined with maxillary sinus floor elevation utilizing the transalveolar approach and nonsubmerged healing for failing teeth in the maxillary molar area. MATERIAL AND METHODS: Patients who required implantation surgry to replace a failing tooth in the maxilla molar region were selected. Patients were randomized into two groups: immediate implant placement combined with maxillary sinus floor elevation utilizing the transalveolar approach and nonsubmerged healing (test group) or delayed implant placement combined with maxillary sinus floor elevation utilizing the transalveolar approach and nonsubmerged healing (control group). The outcome criteria were the success rates of implants, Cone Beam Computer Tomography (CBCT) data and results of the subjective satisfaction survey performed with a visual analog scale (VAS). RESULTS: All implants had good initial stability after implantation. The survival rate of implants was 100% at 1-year follow-up. At the time of permanent restoration, the differences in average horizontal shrinkage of alveolar bone (W1) on the buccal side between the test group (0.65 ± 0.12 mm) and the control group (1.23 ± 0.32 mm) were statistically significant (P < .0001); however, no statistically significant difference (P = .515) was observed on the palatal side (0.3 ± 0.10 mm vs 0.28 ± 0.08 mm). The difference in vertical resorption of alveolar bone (H1) on the buccal side between the test group (0.60 ± 0.18 mm) and the control group (1.53 ± 0.19 mm) was statistically significant (P < .0001), but no statistically significant difference (P = .190) in the reduction of palatal alveolar bone (0.24 ± 0.12 mm vs 0.29 ± 0.13 mm) was observed. After 1-year loading, no statistically significant difference (P > .05) in vertical or horizontal changes (W2, H2) were identified in the test group or control group. Patient satisfaction in both groups was similar (8.36 ± 1.01 vs 8.14 ± 1.35), and the difference between groups was not statistically significant (P = .638). CONCLUSION: Immediate implant placement combined with maxillary sinus floor elevation utilizing the transalveolar approach and nonsubmerged healing is feasible for the maxillary molar area, and the clinical effect is satisfactory.

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.
