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

Mastication is the process of mechanically crushing food to form soft particles, facilitating theingestion process in providing nutrients to the body. One of the objectively assessed mastication functions is mastication performance. The number of tooth losses is one factor that affects mastication performance; the more tooth loss, the lower the mastication performance. Posterior teeth play an important role in mastication function, and loss of posterior teeth decreases mastication performance. The research aims to determine the association between the number of bilateral free-end posterior tooth loss and mastication performance. This type of research is descriptive-analytic with a cross-sectional design. The subjects in this research were 17 people. Data were collected by examining the oral cavity and color-changeable chewing gum to assess mastication performance using a colorimeter. Data were analyzed using the Mann-Whitney test. The results showed that all subjects with bilateral free-end posterior teeth loss in one and both arches had poor mastication performance. The statistical test results showed no association between the number of bilateral free-end posterior teeth loss and mastication performance in one and both arches with p = 1,000 (p 0.05). It can occur because this research does not pay attention to the number of occlusion pairs of posterior teeth and the results of the assessment of mastication performance are not quantitative. The number of bilateral free-end posterior tooth loss can be considered in assessing mastication performance as an educational basis for denture care.

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

Edentulism is the condition of losing all permanent teeth in the upper and lower jaws, which can impair masticatory function. Masticatory performance is influenced by various factors, one of which is the salivary flow rate, which is also affected by age. This study aimed to determine the average salivary flow rate and masticatory performance, as well as their correlation based on age in complete denture (CD) wearers at the Dental and Oral Hospital of Universitas Sumatera Utara. This research is a descriptive-analytic study with a cross-sectional design involving 20 respondents, consisting of 10 adults (aged 19–59 years) and 10 elderly individuals (aged ≥60 years). The salivary flow rate was measured using the spitting method with sugar-free chewing gum, and masticatory performance was assessed using the color-changeable chewing gum method and the Visual Analog Scale (VAS). Results showed that the average salivary flow rate in adults was 3.18 ± 0.91 ml/min, and in the elderly was 2.29 ± 1.29 ml/min. The average masticatory performance score in adults was 3.8 ± 1.14, and in the elderly was 3.4 ± 1.17. Spearman correlation test showed a significant correlation between salivary flow rate and masticatory performance in both adults (p=0.014) and the elderly (p=0.049). In conclusion, there is a significant relationship between salivary flow rate and masticatory performance based on age. Adult patients demonstrated better salivary flow rates and masticatory performance than elderly patients.

Abstract

ABSTRACT Background: Disc Displacement with Reduction (DDWR) is one of the most common temporomandibular disorders (TMD), characterized by anterior displacement of the articular disc during mouth opening, typically accompanied by clicking sounds and masticatory muscle pain. DDWR is frequently associated with local myalgia, often worsened by stress and parafunctional habits. Stabilization splints and infrared therapy have demonstrated effectiveness in reducing symptoms. The use of aluminum wax in bite registration helps achieve a stable centric relation, enhancing splint fabrication accuracy. Objective: This case report aims to describe the management of DDWR with local myalgia and arthralgia through bite registration using aluminum wax to support centric relation during stabilization splint fabrication, complemented by infrared therapy. Case Report: A 40-year-old male reported pain in the left cheek and ear, along with clicking during jaw movement for six months. DC/TMD Axis I assessment confirmed DDWR with local myalgia and arthralgia, Axis II revealed psychological stress. Treatment consisted of behavioral counseling, infrared therapy applied to the left masseter, and splint fabrication with bite registration using aluminum wax. Registration was performed using baseplate wax combined with aluminum wax on the occlusal surface to achieve centric relation during articulator mounting. After two weeks, the patient experienced increased mouth opening from 45 mm to 46 mm, reduced muscle tenderness, and improved muscle relaxation. Conclusion: The combination of behavioral counseling, aluminum wax-assisted bite registration for splint fabrication, and infrared therapy proved effective in reducing symptoms and improving mandibular function in a patient with DDWR and local myalgia.

Abstract

ABSTRACT: Background: Temporomandibular joint disorder (TMD) is a multifactorial condition involving the masticatory muscles and temporomandibular joint. Temporomandibular joint osteoarthritis (TMJ OA), is a degenerative joint disorder marked by articular surface erosion, crepitus, and joint pain. Parafunctional habits such as bruxism can exacerbate OA by increasing biomechanical load on the TMJ, accelerating joint degeneration, and worsening symptoms. Conservative treatments such as stabilization splints are commonly used in TMD management. Recently, botulinum toxin (BTX) type A has gained attention as an adjunct therapy for reducing excessive masticatory muscle activity. Objective: This report aims to describe the multidisciplinary management of a complex TMD case using 3D-printed stabilization splints combined with BTX type A injections. Case Report: A 24-year-old female presented with jaw pain and crepitation sounds upon mouth opening. She reported a history of bruxism and unilateral mastication. Cone-beam computed tomography (CBCT) revealed condylar erosion, osteophyte formation, and flattening. Clinical and radiographic findings confirmed myofascial pain and arthralgia with TMJ OA exacerbated by bruxism. Treatment included a custom 3D-printed stabilization splint and BTX type A injection into the masseter muscle. After 1 week, mouth opening improved from 34 mm to 35 mm, and to 38 mm after 1 month. The patient reported decreased pain during mastication and waking, along with reduced bruxism frequency. Conclusion: A multidisciplinary approach involving 3D-printed stabilization splints and BTX type A injections is effective in alleviating pain and improving function in complex TMD cases associated with bruxism.

Abstract

Background: An unfavorable jaw relationship, such as Class III, contributes to uneven masticatory stress distribution, accelerating alveolar bone resorption and potentially resulting in a flattened ridge morphology. This condition directly impacts denture stability and retention. Therefore, selecting an appropriate occlusal scheme is essential to guide and balance masticatory forces, enabling more even and physiological stress distribution. However, there is currently no clear consensus on the most effective occlusal scheme for Class III jaw relationships with flat ridges. Objective:This systematic review aims to evaluate and synthesize current scientific evidence regarding the influence of different occlusal schemes on stress distribution in patients with Class III jaw relationships accompanied by flat alveolar ridges. Methods: Following the PRISMA guidelines. A comprehensive electronic search was conducted through PubMed, Cochrane, and ScienceDirect databases to identify relevant studies published between 2015 and 2025. The search strategy included keywords such as: (“alveolar ridge” AND “occlusal schemes”) AND (“stress distribution”), as well as (“alveolar ridge” OR “occlusal schemes”) AND (“stress distribution”). Results: Out of 1061 articles screened, five studies met the inclusion criteria. Lingualized and balanced occlusion demonstrated a more uniform stress distribution compared to monoplane occlusion, particularly in patients with Class III jaw relationships and flat ridges. Conclusions: Occlusal schemes play a crucial role in reducing masticatory stress, especially in patients with Class III jaw relationships and flattened alveolar ridges. Further research is recommended, particularly in vitro biomechanical studies using masticatory simulation models that better represent the clinical conditions of Class III patients with flat ridges. Keywords: occlusal schemes, stress distribution, alveolar ridges, Class III.

Abstract

Background: Severe mandibular alveolar ridge atrophy, common in geriatric patients, compromises the functional success of complete dentures due to a reduced denture-bearing area and the proximity of muscle attachments to the ridge crest. This condition increases denture displacement during function in both horizontal and vertical movements, leading to poor retention and stability of the denture. Accurate impression techniques are critical to overcoming these challenges. The closed-mouth functional impression technique allows for the recording of denture-bearing areas and peripheral seal under functional pressure, potentially enhancing retention.Objective: This case report aims to describe the procedure for fabricating a complete denture using a modified custom tray with a closed-mouth impression on a fully edentulous, compromised mandibular flat ridge.Case Report: A 52-year-old woman presented with a loose and poorly fitting lower denture. Clinical examination revealed complete edentulism with a severely resorbed mandibular ridge. A custom tray was fabricated with a detachable handle to support the closed-mouth impression technique without interfering with occlusion during border molding and impression-making. The closed-mouth approach allowed for better muscle molding, recording of functional borders, and a more accurate reflection of the patient’s oral dynamics. As a result, the final denture exhibited significantly improved retention and comfort during function. This case highlights the clinical advantage of the closed-mouth impression technique in managing challenging ridge conditions and emphasizes the practical benefit of modifying tray design to ease the procedure for both clinician and patient. Such adaptation is especially relevant in geriatric care, where functional and anatomical limitations are common.Conclusion: The use of a modified custom tray with the closed-mouth functional impression technique proved effective in managing a severely resorbed mandibular ridge. It resulted in a stable, retentive, and comfortable complete denture, contributing to enhanced patient satisfaction.
