Aim: This clinical research designed to estimate Patient Satisfaction and Oral Health Related quality of Life in Partial Maxillectomy Patients receiving Definitive Obturators Fabricated from Combination of Polyetherether Ketone, Heat Cure PMMA, and Silicone-Based Soft Liners. Materials and Methods: 12 individuals with acquired maxillary defects were selected to undergo prosthetic rehabilitation with obturator fabricated from combination of PEEK framework, heat cured PMMA lined with silicone. Clinical Evaluation determined the classification and extension of maxillary defects. A grading method was used to assess how the definitive obturator is retentive and stabile. The self-described effectiveness of definitive obturator was assessed using Obturator Functioning Scale and visual analogue scale. Results: Clinical results revealed that most of participants were classified as Class III Aramany classification and many of them expressed that their obturators were appropriately retentive and stable. There were close correlations in between the Aramany classification and the retention. The Obturator Functioning Scale expressed acceptable satisfying results regarding mastication, speech, and appearance. These results were improved during the follow-up periods after 3 and 9 months. The patients exhibited an average VAS score of 59.99 mm. (SD +19.46 mm, medium 65.00 mm, (0-100 mm). Conclusion: A combination of PEEK framework and heat cure PMMA lined with silicone proved to be a successful and well-tolerated material for obturator fabrication with several advantages in terms of weight, biocompatibility, good retention and stability and patient's positive response and satisfaction.
