Achieving symmetry is no longer a mystery - Iris Postioning Device: A case report

The Journal of Indian Prosthodontic Society | Volume 20 | Supplement 1 | December 2020 S27 prosthetic methods like maxillomandibular fixation, implant supported prosthesis, removable mandibular guide flange prosthesis and palatal ramp restoration. In order to achieve normal maxilla-mandibular relationship a provisional appliance either mandibular guide flange or palatal ramp prosthesis can be fabricated. Once the patient is able to achieve the proper mediolateral position of the mandible for occlusion of the natural teeth but is unable to repeat this position consistently for mastication, guide-flange prosthesis can be considered. Methodology: Intially a palatal ramp appliance was fabricated for retraining of mandibular musculature in order to functionally reposition the residual mandibular segment and then treated with definite mandibular prostheses with a guide flange to restore the function and esthetics. Conclusion: Mandibular guide flange or palatal ramps are normally utilized as training device. However, in a longstanding case, definitive mandibular prosthesis with a guiding flange and acrylic teeth on the resected side to stabilize the occlusion and to restore the esthetics can be used successfully to correct the deviation and achieve acceptable occlusion for normal mandibular function.
