Treating of fully edentulous mandible using four compressive implants immediately loaded with overdenture: case report

Introduction: The treatment of fully edentulous lower jaw is truly challenging among the dentists. Using contemporary acrylic denture is conventional method in those situations. However, this solution has several disadvantages: insufficient retention, stabilization, lack of comfort, difficulties for patients in mastication, speech and swallowing. Aim: The main goal is to hightlight the benefits of usage compressive implants immediately loaded with overdenture. Case description: We are presenting a female patient at the age of 62 without any medical issues. Intraorally, we diagnosed fully edentulous mandible, treated with conventional acrylic denture. All clinical and paraclinical examinations such as 3D CBCT and anatomical studio models were made. After discussion about the available treatment options, we decided to insert four compressive implants with multi-unit platform in the anterior part of the mandible between the mental foramens. Inserted implants are immediately loaded with overdenture. Implants were inserted using full thickness flap with mid-crestal incision. During the implantation, we achieved implant torque between 35N/cm and 45N/cm. The final impression was taken after 72 hours, with the close-tray method by using specially designed transfers for compressive MS implants. On the final cast with implant analogs, dental technician used burnout abutments for producing milled bar. The bar and the implant platform are connected by the screw-retention method. The milled bar is used for enhancing the retention and stability of the acrylic denture. After 48 hours throughout the principle of occlusal rims, vertical dimension was registered. In the next phase the wax try-in of the denture was performed and when the denture was finished, it was delivered to the patient. Conclusion: With this treatment option, we are preventing bone resorption in the anterior part of the mandible. Denture achieves better retention and stability. Patients are getting better oral health related quality of life as a result of improvements in mastication, speech and swallowing. The dental hygiene is easily maintained due to the screw-retention.
