Abstract

Abstract: Purpose: The study aims to evaluate the long‐term clinical outcome of immediate loading of implants in the edentulous mandible. Materials and Methods: Patients were treated at least 1 year prior to evaluation, with four to five implants and an immediate provisional bridge in the edentulous mandible. They were invited for a clinical examination, which included the removal of the bridge, probing, perio‐testing, clinical photographs, and a new radiograph to determine the bone level. Also, patients were requested to answer the OHIP‐14 questionnaire to rate their satisfaction with the treatment. Results: Forty‐six patients (21 men, 25 women), mean age 60 years (SD 8.5, range 43–77), were treated with 211 implants. One implant failed to integrate, resulting in a survival rate of 99.5%. After a mean follow‐up of 90 months (SD 45, range 17–143), the mean bone level was 1.17 mm (SD 0.49, range 0.36–4.88). The mean Periotest value was −5.48 (SD 0.883, range −2 to −7). The mean probing depth was 2.04 mm (SD 0.71, range 1.00–8.25). There were 83.3% of the implants that demonstrated no bleeding at probing. Calculus was observed at 13.9% of the abutments. Around one implant (0.5%), suppuration was seen after probing. There was a highly significant correlation between bone loss and probing depth ( p < .001). Overall, patients were very satisfied, with 69.6% scoring their treatment as excellent. Conclusion: Immediate loading of surface‐enhanced implants is a highly predictable and successful treatment modality in the edentulous mandible.
