Abstract

Background: Adhesive bridge is a fixed denture with minimal abutment preparation attached with resin cement. Exposure of the dentin during preparation in the posterior region causes frequent detachment of the adhesive bridge. This is due to the presence of fluid and changes in the smear layer on the dentinal tubules, to increase bond strength, the intraoral abrasion method was developed. Intraoral abrasion is a mechanical technique using air and water sprays to produce tooth surface roughness while increasing bond strength without damaging the tooth structure. Objective: One of the intraoral abrasion materials used is aluminum oxide (Al2O3). One of the operating parameters of intraoral abrasion that can affect bond strength between resin cement and the tooth surface is pressure. Optimal intraoral abrasion pressure with Al2O3 and the right type of resin cement aims to create tooth surface roughness while increasing the bond strength of resin cement in adhesive bridge restorations. Conclusions: The success of adhesive bridges, especially in the posterior area, cannot be separated from the role of optimum intraoral abrasion pressure on the tooth surface. The correct use of intraoral abrasion pressure can increase the bond strength of resin cement on the tooth surface while reducing tooth structure damage. Keywords: adhesive bridge, adhesive resin cement, intraoral abrasion, alumunium oxide, water airborne abrasion.

Abstract

Background: One of the successes in making an ocular prosthesis is sufficient eye socket condition, so post-enucleated patient treatment with lower eyelid laxity is a challenge for prosthodontists due to its difficulty in obtaining the retention of an ocular prosthesis. Long-term use of an ill-fitting ocular prosthesis will cause lower eyelid laxity and irritation due to the movement of the prosthesis that is insubordinate with the eye muscles when it is functioning. Objectives: This paper represents the management of lower eyelid laxity in a post-enucleated patient with pressure using conformer and custom ocular prosthesis. Case Report: A twenty-year-old female patient came to Dental Hospital Universitas Sumatera Utara with a red, swollen, and frequent discharge from the eye socket. The custom ocular prosthesis used by the patient often falls out of the socket and she requests a new custom ocular prosthesis. The patient was referred to an ophthalmologist for irritated socket. Then, a definitive impression is made. Two sclera waxes were fabricated in a definitive cast to obtain a conformer and custom ocular prosthesis. Conformer was worn for three weeks to ensure an adequate lower eyelid. Then, a new custom ocular prosthesis was inserted into the socket. Pressing the conformer towards the lower eyelid will stimulate and train the eyelid muscles to move and prevent atrophy, so it can restore the support of the lower eyelid. Conclusion: Lower eyelid laxity can be corrected with a pressure-assisted conformer, resulting in a functionally and aesthetically pleasing custom ocular prosthesis. Keywords: conformer, ocular prosthesis, lower eyelid laxity

Abstract

Background: Denture-bearing areas in edentulism are unable to tolerate masticatory load because of severe alveolar ridge resorption, which decreases masticatory function in the stomatognathic system. Due to the cushioning effect, the use of soft denture liner (SDL) helps reduce the masticatory load placed upon the denture-bearing areas. The physical properties and thickness of SDL have an impact on the stress distribution and cushioning effect. The masticatory load will harm the alveolar ridge and lead to more severe resorption, when modulus elasticity of SDL lower than the mucosa. The stress distribution of the masticatory load can be analyzed more accurately in-silico study using Finite Element Analysis (FEA) method. Objectives: In this paper, the stress distribution in denture-supporting areas with various SDL thicknesses is evaluated using FEA. The thickness of SDL contributes to the distribution of stress upon the denture-bearing areas by minimizing the masticatory load. Conclusion: Through the same modulus elasticity of the mucosa and SDL is able to equally distribute stress on the denture-bearing areas. Keywords: stress distribution, denture-bearing area, soft denture liner thickness, finite element analysis

Abstract

Background Adhesive Bridge is a fixed denture that is attached to the tooth structure, especially the enamel, which has been etched to achieve micromechanical retention. Among other things, adhesive bridge attachment depends on, one important factor is the adhesive bond between the etched enamel and the retained metal. To increase the retention of adhesive bridges, variations of micromechanical surface treatment on metal can be carried out in the form of chemical or electrical etching, air particle abrasion (sandblasting), primary metal, tin plating, silica coating, and lasers. Objective Lasers with different energies, strengths, frequencies, wavelengths, durations and distances can create a thin layer of porous oxide which increases the bonding strength of resin cement for adhesive bridges. The role of laser power and frequency as well as the selection of the right type of resin on the metal surface of the adhesive bridge can increase the bonding strength of the resin cement on the adhesive bridge. Conclusion The selection of the type of surface treatment such as laser and the right type of resin cement can affect the bond strength of the resin cement on the adhesive bridge.

Abstract

Denture stomatitis (DS) is a pathological change in the oral mucosa that commonly occurs in denture users, which is characterized by an inflammatory reaction and erythema in the oral mucosa that is in contact with the denture. Cli-nical manifestations often include red lesions due to excessive occlusal trauma, frequently occurring in the palatal mucosa region. Loose and unstable prosthesis use can also be a predisposing factor for DS. This paper discusses cases of DS in patients with complete dentures (CD) and partial complex dentures. Chronic irritation due to heavy traumatic occlusion results in reduced stability of dentures. The fabrication of CD with proper vertical dimension set-ting and selection of smaller teeth elements can reduce progressive alveolar bone resorption. The use of topical gel medication like Oxyfresh can be an alternative in the clinical management of DS cases. Control of systemic conditi-ons, especially in the presence of comorbidities, is crucial to minimize the risk of DS occurrence and expedite the healing process if it does occur. Maintaining oral hygiene and denture cleanliness are also key factors for the suc-cess of optimal denture care.

Abstract

Treatment for the patient with cleft lip and palate (CLP) requires an interdisciplinary team concerned with improving the patient’s quality of life. This case evaluates the influence of comprehensive therapy on unilateral CLP complete dextra within a 4-year follow-up. A  4-days-old female patient visited a government hospital in Bandung after being referred to a pediatric clinic in the same hospital. The patient was born at 3.2 kg weight with no underlying medical conditions or syndromes. Intraoral examination revealed cleft soft and hard palate and separated alveolar segment. Extraoral examination revealed cleft lip unilateral dextra and shortened columella. The patient underwent compre-hensive therapy including presurgical NAM (PNAM), labioplasty, nasoalveolar molding (NAM), veloplasty, speech therapy, and palatoplasty. It is concluded that early treatment of PNAM reduces the severity of the orofacial deformi-ty, induced the reposition of soft & hard tissue and there’s an improvement in intelligibility and production of pharyng-eal sounds and velopharyngeal closure when using intravelar veloplasty in palatal repair along with NAM. In the fourth year of life, the patient has capable on communicates with intelligibility pronounce with relative adequate arch.

Abstract

The aging process causes changes in the anatomical structures of the oral cavity and pharynx that are closely re-lated to the ability to chew and swallow. The use of a complete denture may prevent this to happen, but a lower mastication pressure is visible in complete dentures compared to natural teeth. This may have an impact on swal-lowing ability. In general, a complete denture improves the swallowing process and prevents oral cavity and pha-rynx changes. Several factors, such as denture thickness, the interaction of oral musculatures with the denture, and occlusal contacts will affect the effectiveness of the swallowing process. A proper and stable denture will improve the pharyngeal movement involved in swallowing, thus avoiding airway obstructions. It is concluded that the use of a proper complete denture is important as all four phases of the normal swallowing process are affected by the den-ture. Untreated edentulous jaws may cause oropharyngeal expansion which increases the risk of food bolus pene-tration into the hypopharynx and ultimately delay the pharyngeal swallowing process

Abstract

Digital impression of partial edentulous in removable partial denture requires special attention, based on Kennedy's classification, amount of tooth loss and position will affect the accuracy of digital impression. Factors affecting accuracy of intra oral scanner are handling and learning, powdering, lighting, scanning distance, and scanning strategy. The scanning strategy is a certain movement when scanning to improve the accuracy of the virtual model. The accuracy of the scanning strategy in digital impression can be assessed based on trueness and precision. This literature review aims to explain the various scanning strategies on partial edentulous on digital impression accuracy. Most IOS manufacturers recommend specific scanning strategies. In removable partial dentures, it was found that modified scanning strategies were more accurate than the manufacturer's recommended scanning strategies in some clinical situations. For cases in Kennedy Class IV and Class III maxillae the scanning strategy from occlusal to palatal and then to buccal proved to be more accurate. In Kennedy's Class I maxilla, the T-R (Teeth-Ridge) strategy was more accurate than the M (Manufactured) and R-T (Ridge-Teeth) strategies with reduced seesaw effect and high stabilization of the partial removable denture framework. This requires special strategies that depend on the IOS system. The scanning strategy affects the accuracy of digital impression, where the manufacturer's recommended scanning strategy is not necessarily better than the modified scanning strategy. In addition, the location and case of tooth loss also affect the scanning strategy. Key word: strategy scanning, digital impression, trueness, precision, intra oral scanner

Abstract

Eyes are one of the most important organs of the body which are set inside the protective orbital bone. Loss of an eye can be caused by congenital defects, trauma, or tumors. The removal of the eyeball (enucleation) may cause a massive impact on the self-image, confidence, and personality of an individual. Acceptable cosmetic results usually can be obtained with an ocular prosthesis which is an artificial maxillofacial prosthesis to replace the lost eye. This paper describes the prosthetic rehabilitation of a 71-year-old male patient with a left ocular defect accompanied by a contracted socket caused by the poorly fitting old prosthesis which results in subpar cosmesis. The soft tissue around the eye is normal, but the palpebral conjunctiva forms an abnormal adhesion to the eye socket. An impression was made using a custom tray and alginate in the defect area, followed by filling the impression with gypsum type 3 to get a working model, from which a wax model was made and adjusted to the patient. Sclera and ocular acrylic prostheses were made on the basis of an adjusted wax model. The prosthesis was then polished and colored according to the contralateral eye, followed by the manufacturing of an artificial palpebra made of silicone for a more aesthetic result. The custom-made eye prosthesis with silicone palpebra is an artistic solution for the treatment of ocular defects with contracted sockets. This technique was able to improve the patient’s psychological and emotional status.

Abstract

Ceramic materials are among the materials used in restorative dentistry. They are widely used for restoration in esthetically demanding areas. Consequently, this material requires excellent color stability on top of adequate strength and good biocompatibility to achieve prosthodontic treatment success, especially in the aesthetic aspect. Lithium disilicate and zirconia are two popular ceramic materials used in dentistry mainly due to their translucency and strength. This scoping review aims to evaluate the potential for ceramic materials, mainly lithium disilicate and zirconia, to change colors after thermocycling with or without the staining process. Thermocycling is a laboratory method used to simulate daily oral use in relatively short periods. Twelve (12) articles extracted from 172 articles in 3 database resources based on the inclusion and exclusion criteria (journal articles in English from 2017-2021 that evaluate the color change in ceramic materials after thermocycling with or without staining process) are reviewed for the color change of several ceramic restoration materials. All materials generally show color change; lithium disilicate and zirconia-reinforced lithium silicate show the slightest color change compared to zirconia, feldspathic, or hybrid ceramic materials. Glazed materials offer better color stability compared to polished materials. Several staining solutions significantly contribute to the color change: coffee, tea, and wine. The thickness of materials and adhesive cement may also contribute to the color change of ceramic materials. In conclusion, all materials show color change after the thermocycling process; however, only hybrid ceramics show a level of color change that is above the tolerated limit. Keywords: ceramics, color change, lithium disilicate, thermocycling, zirconia
