BACKGROUND: Magnetic attachments can provide a long-term reliable retention force and significantly improve the retention and stability of complete overdentures to reduce the alveolar ridge absorption availably as well as improve masticatory efficiency and repairing effect.
OBJECTIVE: To observe the clinical effect of Magfit magnetic attachment on the complete overdenture retention and its effects on the health of abutment teeth.
METHODS: Thirty-six patients with tooth loss were included, and 1-3 abutment teeth on one jaw were selected and treated with Magfit EX magnetic attachment in overdentures. Fifty-seven overdentures were made, including maxillary 27 and mandibular 30,  totally 96 magnetic attachments in number.
RESULTS AND CONCLUSION: All cases were followed up for 6 to 36 months. Thirty-four cases felt comfortable for overdentures, two cases who felt unwell at the beginning received regulation and adaption, then they felt well. Thirty-three cases had better masticatory function recovery, among whom, three cases recovered better in the masticatory function, but had a decrease in the retention force that was improved after regulation. One case felt abutment tooth painful that relieved after jaw regulation. Five cases of abutment tooth mobility were improved. Two cases of gingival redness and hyperemia had a relief after symptomatic treatment. One case’s moving attachment was fractured partly. These suggest that the magnetic attachment can provide a long-term reliable retention force and contribute to the health of abutment teeth.
