EFFICACY OF MAGNETOTHERAPY IN SOFT TISSUE MANAGEMENT AFTER DENTAL IMPLANTATION: RESULTS OF A RANDOMIZED PLACEBO-CONTROLLED TRIAL

Abstract

Aim.  To evaluate the efficacy of low-frequency magnetotherapy on soft tissues around installed implants in the postoperative period.

Material and methods. A double-blind, placebo-controlled, randomized trial was conducted. Fifty patients were divided into a main group (n=25) and a control group (n=25). The main group received a course of magnetotherapy for 10 days after surgery. The control group underwent identical procedures using a switched-off device. Efficacy assessment included the dynamics of the bleeding index, mucosal thickness, microcirculation parameters, severity of pain syndrome, assessment of the gingival level relative to the cementoenamel junction of the adjacent tooth, and measurement of the width of keratinized gingiva.

Result. The main group showed a significant increase in microcirculation parameters (p≤0.05), a reduction in bleeding indices after 14 days (65% - main group, 25% - control, p≤0.05) and after 3 months (12% - main group, 28% - control, p≤0.05). A greater mucosal thickness was observed (2.8±0.3 mm - main group, 2.1±0.4 mm - control, p≤0.05), along with faster relieving of pain syndrome (need for analgesics: 2±3 days in the main group vs. 4±5 days in the control group, p≤0.05), a lower level of recession after 3 months (0.2±0.1 mm vs. 0.5±0.2 mm, p≤0.05), and an increase in the width of keratinized gingiva.

Conclusion. Low-frequency magnetotherapy significantly accelerates healing, promotes the formation of a more stable and dense mucosal lining, and improves patient comfort after dental implantation, allowing it to be recommended as an effective adjuvant method.
