Abstract

Introduction: Tumors increasing frequency in maxillo-facial region is the reason for developed of patient’s cases of maxillary resection. Immediately after the operative resection some defects are appeared and provoke patient’s speech, mastication and esthetic damages in different stages. Depending on size and defect location prosthetic and surgery methods are usually applied.
Aim: The main goal of this clinical research is to present treatment approach for solid obturator making for the task of healing patients with a great maxillary defects and to assess its effectiveness on patient’s speech, mastication and swallowing restoration and rehabilitation.
Materials and methods: One clinical case is analyzed. Patient with maxillary defect after the surgery resection is presented. Intraoral examine shows resection of the right part of the alveolar ridge and upper jaw. It is observed that alveolar ridge after 13 is not destroyed and dentition is saved. Because of defect localization and its retentiveness treatment plane is buildet involving solid obturator making. Alginate impressions are taken from the both jaws. Next step is preparing of individual tray from light cured resin used for functional impression in wax lining of the prosthesis borders and silicon cream application. What is followed is preliminary wax modeling of the gypsum master cast for avoiding undercuts and retentive regions. After the model duplicating retentive two wire clasps are fixed on 13 and 26 allowed prosthesis retention and stability. Next step is occlusal centric relation fixation by occlusal rims and checking the artificial teeth arrangement. Finally, high temperature polymerization is processed. Prosthesis is acrilyzed and polished.
Results: Good sealing is achieved. Tight penetration of the obturator part allows fast restoration of the patient’s speech, mastication and swallowing and rehabilitation. Results are very satisfied. Both of them occlusal height and obturator height provide right articulation and normal breathing. Despite the greater obturator weigh a very good retentiveness end stability are observed. Preliminary reduction of the obturator height gave possibility for successful restoration of the destroyed functions.
Conclusion: Prosthetic treatment with a solid obturator is a relatively rarely used method for the treatment of patients with large maxillary defects. However, the presented clinical case showed that the presence of teeth, the favorable location of the defect and the use of an appropriate technique allows the successful restoration of damaged functions.
