Abstract

Menggantikan kehilangan gigi anterior membutuhkan pertimbangan estetika yang matang karena terlihatnya servikal gigi dan jaringan lunak sekitarnya saat tersenyum. Ovate pontic merupakan pontik yang dapat memberikan hasil estetika paling baik. Dasar pontik berbentuk cembung untuk mendapatkan emergence profile optimal. Komplikasi pencabutan mengakibatkan resorpsi besar dan masalah estetik sehingga diperlukan tindakan preprostetik bedah augmentasi untuk mempersiapkan ruang bagi gigitiruan. Dilaporkan seorang laki-laki, gigi 11 fraktur 1/3 apikal akar, ingin gigitiruan cekat yang dapat memperbaiki penampilan. Saat pencabutan terjadi kerusakan alveolar ridge akibat ekstraksi sulit sehingga membutuhkan bedah augmentasi untuk mengatasi defeknya. Untuk itu gigitiruan jembatan (GTJ) imidiat sementara dengan ovate pontic disiapkan dengan mengasah duplikat model studi area 11 sedalam 2,5 mm dan 1 mm ke lateral sebagai panduan proses penyembuhan, lalu dilakukan preparasi gigi penyangga 12, 21, dan 22. Saat pencabutan terjadi kerusakan alveolar ridge, direhabilitasi dengan bedah augmentasi menggunakan bone graft. GTJ imidiat sementara dipasang dan dikontrol selama 6 bulan sejalan dengan proses penyembuhan. Dasar pontik disesuaikan hingga didapatkan emergence profile yang optimal. Disimpulkan bahwa pencabutan gigi fraktur di regio anterior disertai komplikasi defek alveolar ridge membutuhkan perawatan preprostetik dengan bedah augmentasi dan GTJ imidiat sementara dengan ovate pontic untuk mendapatkan emergence profile optimal bagi GTJ definitifnya.

Abstract

Introduction: Maxillary defects are probably the most common of all intraoral defects. Moreover, their size and location affect the degree of difficulty in prosthetic rehabilitation. Maxillary defects may be divided into two types: (i) defects resulting from congenital malformations and (ii) acquired defects resulting from surgery for oral neoplasms. Acquired maxillary defects in the form of postsurgical defects can cause conditions such as nasal voice (hypernasal speech), nasal cavity leakage, mastication function deterioration, and considerable facial collapse due to extensive bone loss. Case Report: A 34-year-old male patient with resection—without prior surgical or interim obturator placement—performed in 2018 on the premaxillary segment and anterior maxillary alveolar ridge came to the Department of Prosthodontics, Faculty of Dentistry, Universitas Indonesia (Depok, Indonesia). The prosthetic rehabilitation goals for this case included the separation of oral and nasal cavities to allow adequate deglutition and articulation, possible support of the orbital contents to prevent enophthalmos and diplopia, support of the soft tissue to restore the midfacial contour, and an acceptable aesthetic result. In this clinical report, a maxillary obturator prosthesis framework was used as a definitive treatment. Conclusion: A proper and detailed treatment sequence is critical for successful prosthetic rehabilitation of a dentate maxillectomy patient. A considerably successful maxillary obturator indicator, such as masticatory function and distinct speech, was regained. The nasal cavity leakage problem was solved after sealing the gap between the oral and nasal cavities by providing adequate extensions of the flange.
