Surgical Management of a Severe Early Implant Complication: A 19‐Year Follow‐Up Case Report
Bibliographic record
Abstract
INTRODUCTION: Reports on long-term response to treatment of different implant complications with a span of more than 15 years are scarce. This case report presents a patient with early severe bone loss around an unloaded dental implant, with treatment and 19-year follow up. CASE PRESENTATION: A 60-year-old male non-smoker with no known systemic contributory history presented for replacement of the mandibular right first molar. The tooth was replaced with a titanium plasma-sprayed (TPS) implant using a non-submerged healing approach. Eight weeks post-surgery the patient reported discomfort in the area, followed by swelling, suppuration, and deep probing depths (PDs). A full-thickness flap revealed a bone defect that was thoroughly debrided until its deepest extension. The implant surface was scaled and subjected to air-powder treatment, followed by rubbing the TPS surface with a cotton pellet soaked in HCl-tetracycline. Guided bone regeneration was accomplished with use of an allograft followed by placement of a non-resorbable membrane. Follow-up after 19 years showed stability of the bone gain and reduction of PDs. CONCLUSION: The 19-year successful long-term result calls attention to the potential benefit of the combined anti-infective/regenerative approach and lasting effects of surgical management of early implant complications.

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.
