Keywords: resection of the mandible, resection implant, endoprosthesis.


Partial arthroplasty of the lower jaw at the present stage is one of the alternative methods of rehabilitation of patients with tumors or traumatic injury maxillofacial area. Project resection implant automatically using special CAD / CAM software.

The aim of our study was to design the resection implant (endoprosthesis) of chin areas of the mandible.

The challenge was to design a computer endoprosthesis that most accurately reproduce the shape and size of bones, shattered pathological process and allowed to carry out effective dental prosthetics based on dental implants.

For information on the exact geometry of the lower jaw and place of destruction carried out scanning the patient's face and Cone-beam CT scanner on the unit PAX-Zenit 3D slice thickness of 0.1 mm, followed by an analysis of the data in the program Mimics.

For the design of the implant resection of chin areas of mandible an analysis of CT scans of the patient B., 26 years old was used. The front of the lower jaw, including the area chin torus, began to collapse as a result of a benign tumor. An analysis of the received set of image format DICOM was performed. For processing images and create 3D-models continue to use the system of processing medical data Materialise Mimics (Belgium, 1992-2014). After creating a project import it image CT. On the basis of built 3D-model. It was created solid models applications Cad-system Delcam Powershape. It was determined the limits of resection, they pass no closer than 2 mm to the affected tissue. It was build internal and external surfaces of the prosthesis. Then the lateral and upper and lower surfaces. It was created fasteners prosthesis to the jaw and a smooth transition from their bases to the outer surface of the prosthesis.

The next step is adding surface that correspond to the installation site abutments. In this case, the size used for two-stage implant Vitaplant V2Km 400 (d = 4 mm, l = 10 mm). Build appropriate surface carving part, hexagon and conical surfaces. Based on the model established pattern, the edge of which resect jaw. Template during surgery is applied to the front part of the bone and fastened in places where the prosthesis in order to accurately passed resection. All models are tested after creating the required " doctor body" to ensure that no defects such as holes are invisible, overlay surfaces, defective points, gaps and others.
