Use of the Occlusal Device for Prosthetic Rehabilitation in a Patient with the Absence of the Right Mandible Branch

Flaws in the control of dental caries and periodontal disease, possibility of root fractures and the difficulty in understand and reproduce the bilaterally balanced occlusion, takes many professionals to be reluctant to indicates this technique, preferring to remove remaining teeth and install implants [3,4,6]. However, the use of natural tooth roots to support overdentures brings benefits to the patient, assisting the proprioception, eliminating the osseointegration period and reducing the final cost of the prosthesis, because it eliminates the need for the acquisition of prosthetic components, and clinical and laboratory procedures related to installation of implants. Maintaining compliance with oral hygiene and specific care with the natural supports and prosthesis, the time life justifies the indication of this technique. In addition, an appropriate treatment plan for the making of overdentures on natural roots is a mandatory choice for patients who have underwent radiotherapy as a complementary treatment of cancerous lesions. Several authors are unanimous in stating that the radiation is a factor associated with the loss of implants and the decrease in its survival rate [7–16]. The effects of the radiotherapy appear to be more severe in the jaw due the less blood supply in the newly formed bone. So the benefit of the indication of the overdenture on natural roots in these cases, when compared to the overdenture on implant must overcome risk [7].
