Five-year clinical results of immediately loaded dental implants using mandibular overdentures.
Bibliographic record
Abstract
PURPOSE: The aim of this report is to present the clinical and patient-based outcomes of an immediate-loading protocol of TiUnite implants with mandibular overdentures in edentulous patients 5 years following initial placement. MATERIALS AND METHODS: The study comprised two groups of edentulous patients. In the experimental group, 35 consecutively treated patients received 70 TiUnite implants that were loaded immediately, as well as 69 Branemark machined implants as a backup treatment. One patient received one Branemark implant. The control group comprised patients who were treated previously with conventional two-stage implant procedures, but were all case matched to the intervention group and served as a historical cohort. This group included 42 patients who received 111 Branemark implants. Both groups of patients were treated with overdentures that were supported with a standardized resilient bar mechanism. Clinical and patient-based outcomes in the immediate group were recorded for the first 5 years following the initial placement of implants and were measured at various stages of treatment using two questionnaires: the Denture Satisfaction Scale and the Oral Health Impact Profile (OHIP-20). RESULTS: Just over 98% of implants were found to be successful in both groups (Fisher exact test: P = 1.000). A statistically significant improvement in patients' total, mandibular, and functional satisfaction scores was found when comparing baseline data to the data obtained 5 years following loading in the experimental group (P < .001). There were no significant differences between the 1- and 5-year total, mandibular, and functional satisfaction scores, or between baseline and 5-year maxillary denture satisfaction scores. A statistically significant and positive correlation was found between baseline and 1-year maxillary satisfaction scores (P = .002). Any improvement in the patients' quality of life (QoL) was maintained during the first 5 years of loading. CONCLUSION: The results of this longitudinal study suggest that immediate loading of two dental implants by means of bar-retained mandibular overdentures is a predictable treatment option and leads to substantial improvement in patients' satisfaction and QoL. Importantly, this mirrors the outcomes found for patients subjected to the more commonly accepted two-stage implant procedure.

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.
