Radiographic and clinical outcomes of rooted, platform‐switched, microthreaded implants with a sandblasted, large‐grid, and acid‐etched surface: A 5‐year prospective study
Bibliographic record
Abstract
BACKGROUND: There is no data available on the long-term outcomes of a rooted, platform-switched, microthreaded implant with a sandblasted, large-grid, and acid-etched surface. PURPOSE: This prospective, longitudinal study evaluated the clinical and radiographic outcomes of rooted, platform-switched, microthreaded and sandblasted, large-grid, and acid-etched (SLA) surface implants for 5 years. MATERIALS AND METHODS: Sixty implants were placed in sixty patients with partially edentulous maxillae or mandibles. The permanent prostheses were inserted 2-4 months after implant placement. Clinical and radiographic examinations were performed at follow-up visits scheduled postoperation, prosthesis installation, 1 year, and 5 years after surgery, to assess implant survival and success rates, biological and mechanical complications, and marginal bone loss. RESULTS: After 5 years' follow-up, four patients withdrawn from the study, and 56 implants achieved a 100% survival rate and 98.2% success rate. Three prosthetic complications occurred, resulting in a success rate for prostheses of 94.6%. The incidence of peri-implant mucositis was 9.1% and no peri-implantitis was diagnosed. The average marginal bone loss at the mesial aspect was 0.46 ± 0.27 mm after 1 year and 0.48 ± 0.27 mm after 5 years. The average marginal bone loss at the distal aspect was 0.46 ± 0.32 mm after 1 year and 0.50 ± 0.35 mm after 5 years. CONCLUSION: After 5 years of loading, the rooted, platform-switched, microthreaded, and SLA surface implants showed high survival and success rates, steady crestal bone levels, and excellent long-term clinical outcomes in the soft tissue. Overloading may be related to the marginal bone loss around implants, but the surgical protocol, different sites, and jaw position did not correlate with crestal bone loss.

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.
