Abstract
The total resection of the superior maxillary bone is mainly indicated in tumours of the infra- and mesostructure.
The wide endo-oral defect residual at the surgical operation causes a number of troubles which are characterized by retraction with sinking of the facial skin flap, rhinolalia, dysphagia with nasal backflow. In most of the cases reported the standardized technique of the operation and its good long-term results allowed a prosthetic reconstruction. The prosthetic reconstruction not only favoured the cicatricial evolution of the endo-oral defect, but also risulted in the rilief of troubles and deficiencies following the surgical demolition, For this purpose, the authors have employed a temporary teeth-free prosthesis, applied 10 to 20 days after the operation and left in position during the first two months, and, later, a permanent prosthesis with teeth. Results were highly sotisfactory both fram a functional and aesthetic standpoint.
The prosthesis was of varying type according to the size of the endo-oral defect as well as to the condition of the remaining teeth. In some cases the prosthesis was supported by steel hooks whereas in other ones Witallium-melted ferrules were anchored to the contralateral teeth. In teeth-free patients the preference has been given to a complete higher and lower prosthesis, with the magnetic system.
