Abstract

The alveolar ridge consists of denture bearing mucosa, sub-mucosa and periosteum, and residual alveolar bone. After tooth extraction, the remaining alveolar bone undergoes a remodeling process that leads to morphological reduction and alteration, which results in the change in alveolar ridge forms. However, it does not change alveolar arch shapes. This literature review aimed to analyze the relationship of alveolar arch shapes with complete denture retention. According to House (1958), alveolar arch shapes classified into three classes: Class I-square, Class II-tapering, Class III-ovoid. Those three alveolar arch shapes have a difference in the denture bearing area, with the largest denture bearing site on Class I-Square alveolar arch shape. Some factors that influence complete denture retention are adhesion, cohesion, interfacial force, oral and facial musculature, atmospheric pressure, undercut, rotational insertion path, parallel walls, and gravity. The alveolar arch shapes can affect retention regarding the size of the denture bearing area.The alveolar arch forms with a wider denture bearing area provide more considerable surface contact between the denture and mucous membranes. The forces resulting from those factors of retention might produce more excellent complete denture retention. The square arch shape is the alveolar arch shape with the largest denture bearing area. Hence, the square arch shape is believed to have the best complete denture retention.KEYWORDS: arch shape; retention; complete denture; denture bearing area

Abstract

Introduction: Flabby ridge compromise support, retention and stability of complete dentures. Thepresence of flabby ridge tends to create a difficulty while making complete dentures. Many impressiontechniques have been proposed to overcome these difficulties. Objectives: This paper aims to explainan impression technique on flabby ridge anterior mandibular using modified final impression tray withtwo tunnels. Case Description: An 80-years-old female patient using complete dentures. She wasconcerned that her lower complete denture was loose. On clinical examination there was anteriorflabby ridge from canine to canine of the mandibular arch. The technique described in this case wasusing clear swapolimerized acrylic resin with two tunnels for final impression tray, using polivynilsiloxane light body impression was injected around the flabby ridge using a dispensing gun from oneside of the tunnel, taking care that the flow to the opposite side was controlled by the clear custom tray,to ensure minimal distortion on flabby tissue and coverage of impression material on all edentulousarea. Discussion: Flabby ridge is a challenge in prosthodontics to achieve stability and retention ofcomplete dentures. Provision of complete dentures in patient with flabby ridge can be managed bycorrect impression method. By using this modified final tray, it will not displace the flabby tissue thatcan dislodge the denture, simple custom tray, easy to practice and less time. Conclusion: Choosingappropriate impression technique and used the right final impression tray may increase patient’sprosthesis stability and retention.Keywords: Flabby Ridge, Modified Impression Tray, Clear Swapolimerized Acrylic Resin

Abstract

Resorpsi tulang alveolar dipengaruhi berbagai faktor yang menyebabkan perubahan bentuk tulang alveolus. Pada pembuatan gigi tiruan penuh, dukungan tulang alveolus diperlukan karena mempengaruhi retensi dan stabilisasi. Tujuan penulisan ini untuk mengetahui hubungan bentuk tulang alveolus dengan retensi gigi tiruan penuh. Klasifikasi bentuk tulang alveolus terus mengalami penyempurnaan. Faktor-faktor retensi pada gigi tiruan penuh adalah adhesi, kohesi, tekanan atmosfer, muskular, tegangan permukaan, gravitasi, daerah gerong, rotasi arah pasang, dan kesejajaran dinding. Bentuk tulang alveolus yang membulat, rata, dan lereng yang sejajar memberikan retensi yang baik karena kemampuannya menahan gaya vertikal dan lateral yang terjadi serta menambah luas permukaan antara gigi tiruan dan mukosa sehingga dapat menambah faktor fisika retensi gigi tiruan. Terdapat hubungan antara bentuk tulang alveolus dengan retensi gigi tiruan penuh.

Abstract

Edentulus merupakan kehilangan seluruh gigi permanen pada maksila dan mandibula yang mengganggu mastikasi, namun dapat dihindari dengan menggunakan GTL. Tujuan GTL adalah tercapainya performa mastikasi yang baik. Keberhasilan GTL disebabkan oleh GTL yang retentif dan stabil yang sebagian besar tergantung pada saliva. Laju aliran saliva penting dalam pembentukan adhesi dan kohesi antara basis GTL dan mukosa. Penelitian ini bertujuan mengetahui hubungan laju aliran saliva dengan performa mastikasi berdasarkan jenis kelamin pada pemakai gigi tiruan lengkap. Jenis penelitian ini adalah deskriptif analitik dengan rancangan penelitian cross sectional menggunakan sampel penelitian pemakai GTL dengan oklusi klas I sebanyak 38 orang, dengan kriteria selalu memakai GTL selama siang hari dan ketika makan serta pemakaian minimal 6 bulan pasca pemasangan di RSGM USU. Setiap pasien dilakukan pengumpulan saliva untuk mengukur laju aliran saliva dan pengunyahan Color Changeable Chewing Gum untuk menilai performa mastikasi, kemudian hasil dianalisis dengan uji Chi-Square. Pada hasil penelitian ini laju aliran saliva memiliki hubungan signifikan dengan performa mastikasi pada laki-laki, namun tidak pada perempuan. Laju aliran saliva dapat dijadikan pertimbangan penilaian performa mastikasi pada jenis kelamin laki-laki sehingga dapat digunakan sebagai dasar edukasi hasil evaluasi mastikasi pemakai gigi tiruan lengkap.

Abstract

Background: Edentulism is an oral health problem that affects the quality of life because of the loss of equilibrium in the stomatognathic system with impaired mastication. This problem can be more deteriorating in the condition of flat ridges, which increases the stress distribution in the mucosa under masticatory load. Stress distributions that exceed the pressure-pain threshold will result in poor masticatory performance, making it critical to choose the ideal occlusal scheme for such ridge conditions. However, the measurement of stress distribution in the mucosa with various occlusal schemes is challenging for in vivo and in vitro testing because of the inability to represent the complex stomatognathic system. In silico testing using finite element analysis (FEA) can be the solution since the modeling simulation is acquired from CT-scan or digital designs and feasible experimental treatments.Objectives: This paper discusses the use of FEA in the measurement of stress distribution in the mucosa, particularly the flat ridges to different occlusal schemes in complete dentures, and its association with pain. Conclusion: The advantages of FEA in obtaining accurate modeling and testing flexibility allow the measurement of stress distribution and its association with pain on flat ridges with different occlusal schemes in complete dentures.
