Statement of problem: Conventional mandibular complete denture lacks in support and stability for edentulous patients to use.
Purpose: To enhance support and stability of mandibular complete denture, 2 implants were inserted on the inter-mental foramina space of edentulous patients. With 2 magnetic attachments on the inner side of the overdenture, we gave immediate loads and evaluated the stability of the implants, the responses of the supporting tissues, and the satisfaction of the patients.
Material & methods: 6 edentulous patients (5 male, 1 female) each recieved 2 SLA implants in the inter-mental foramina region and implants were immediately loaded with overdenture with magnet attachments. To evaluate the implants stability and the peri-implant tissues, clinical exams, RFA tests and radiographic exams were preformed at the 1 week, 2wks, 6wks, 12wks, and 24wks. post- surgery.
Results: The mean surgery time was 45.7{pm}7.7mins. while the denture delivery time was 45.5{pm}12.6mins. Only 2 of 14 implants were failed. Survived implants that remained were clincally and radiographically stable. Mean ISQ values were relatively stable, showing 69.71{pm}5.55, 69.00{pm}9.48, 67.92{pm}7.86, 67.92{pm}9.58, 70.08{pm}7.61, 71.92{pm}6.43 at the 1 wk, 2 wks, 6 wks, 12 wks, 24 wks. follow up check. Crestal bone changes were -1.18mm{pm}0.68mm, -1.35{pm}0.69mm, -1.47{pm}0.68mm at the 6wks, 12wks, 24wks. follow up check. Bleeding on probing(BOP index) was not significant.
Conclusion: Mandibular ovedentures with 2 magnetic attachments over two interforaminal implants on edentulous patients for immediate function is a recommendable novel treatment for edentulous patients which shows stability on the implants and supporting tissue.
