Abstract

Heat-cured acrylic resin is commonly used as denture base materials. The time needed for its polymerization makes the process less efficient. The salt solution has a higher boiling point and more stable molecular bonding, which is expected to shorten the curing time of HCAR. This article determines the influence of salt solution as curing media on curing time and compressive strength of HCAR. This experimental laboratory study used 25 samples of HCAR with 25.4x12.7x12.7 mm by dimension. Samples were boiled in water at 74oC for 120 minutes as a control, in 35% salt solution at 74oC for 30, 60, 90, and 120 minutes as treatment groups, and then all groups were boiled at 100oC for 60 minutes. The compressive strength of each sample was tested using an Autograph AG-10TE. The highest com-pressive strength and fastest setting time were shown in samples boiled in a salt solution for 60 minutes. One-way Anova followed by a post hoc Tukey-HSD test showed no significant compressive strength differences in each group (p>0.05). It is concluded that salt solution usage as curing media fastens the curing time and results in the same compressive strength within all groups.

Abstract

Background : Porcelain fused to metal (PFM) restoration is one of the most common restorations for fixed dentures because of its high strength, durability, biocompatibility, and satisfactory esthetics. The brittle nature of ceramic makes it easily fractured. Porcelain fracture is the second largest failure after caries. Repairing porcelain directly using composite resin becomes an option because it is cost-effective and easy to apply. The repair process requires chemical and mechanical bonding to create a strong resin bond. Hydrofluoric acid (HF) can be used as a surface treatment material to achieve good bonding. Concentration and etching time affect the bond strength. However, HF becomes harmful when in contact with soft tissues. Strict protocols in its application are observed and prolonged use in the mouth is avoided. Objective: To describe the effect of HF as a surface treatment material on bonding strength between porcelain and composite resin. Knowing the HF bonding strength changes to time and concentration as a surface treatment material for direct repair. Conclusion : Minimizing the contact of HF on soft tissues, applying HF in the mouth for a short time without reducing its function to achieve good bonding strength. Keywords : porcelain fused to metal, surface treatment, hydrofluoric acid

Abstract

Retentive force (RF) on the telescopic crown (TC) retainer will be distributed to the abutment teeth. The optimal load distribution measured by RF on the abutment is 5-9 N. If the force is applied excessively, it will damage the tooth's supporting tissue, causing periapical lesions, bone resorption, and mobility. However, if the RF is minimal, the dent-ure will not retentive. This paper will go through how RF will vary based on the chosen design and material. The cy-lindrical, conical, and resilient TC design are affected by the taper angle and the distance between the primary crown (PC) and secondary crown (SC). Resilience design can be modified by Marburg, Hofmann, and Yalisove. To create the precise taper angle and space in telescopic dentures (TD), CAD/CAM can now be used for the manufacture of TD using metal and non-metal materials. It is concluded that cylindrical TC design is rarely used because it is diffi-cult to get tight contact between PC and SC, therefore conus or resilience design is more recommended. The smal-ler the taper angle, the greater the RF, but this depends on the material used. While the space between PC and SC, which is less than 50 μm, can also affect RF

Abstract

Background : Determination of the correct Occlusion vertical dimension (OVD) is one of the factors that dentists need to pay attention to in important dental procedures. One of the most important strategies of restorative care is the assessment andre-establishment of the occlusal vertical dimension. Tooth attrition causes changes in facial morphology dimensions and OVD decreases. Discussion: The occlusion vertical dimension (OVD) was the height of the lower third of the face as measured from the point of subnation to gnathion at the maximum intercuspation position. One of the factors that affect a person's occlusion vertical dimension is the presence of tooth abrasion, attrition and tooth loss. One way to improve a patient's occlusion vertical dimension is by rehabilitative action with restorative treatment by making crowns for teeth experiencing anterior attrition. Conclusion: Tooth attrition causes changes in facial morphology dimensions and occlusion vertical dimension decreases. Determination of the correct occlusal vertical dimension is one of the success factors in rehabilitation treatment, because if it is not restored properly, the guard teeth will decrease, damage to the teeth, muscles, TMJ, swallowing and can occur speech disorders.

Abstract

Background: Midline facial cleft is extremely rare congenital malformation. It may be associated with other syndromes, including West syndrome (WS), a severe form of epilepsy in infancy. Objective: This report presents modified Presurgical Nasoalveolar Molding (PNAM) treatment of midline facial cleft in WS patient. Case Report: An infant girl born with midline facial cleft, characterized by flat nose due to complete absence of nasal cartilage, columella, and premaxilla. She was also diagnosed with WS, hydrocephalus, and cerebral palsy. PNAM treatment was performed, consisting of feeding plate and extraoral nasal hook. The feeding plate prevented tongue protrusion which could interfere the airway during multiple spasms and trained her to place the tongue in its normal position. The extraoral strapping was retracted across the upper lip and feeding plate was grinded selectively to approximate the lip and alveolar segment concurrently. An elastic band was paired on nasal hook and attached to the forehead to elevate nasal dome and maintain the airway during retraction. After 1 year follow-up, alveolar gap was reduced by 4,5mm, lip segment moved closer to the midline, and bodyweight increased sufficiently. Conclusion: Modified PNAM can help infant with WS breath, increase nutritional intake and mold the alveolar tissue properly. Keywords: midline facial cleft, West syndrome, modified PNAM

Abstract

The maxillary defect can interfere a patient’s speech, masticatory, aesthetic and psychologic. To overcome this problem, an obturator prosthesis is needed. This case report focuses on prosthetic rehabilitation for Aramany’s class II patient. In January 2022, a woman, 46 years old, was diagnosed with recurrent cavum nasi cancer. She got a subtotal maxillectomy at RSUP Dr. Sardjito. After maxillectomy, the patient was assigned a surgical obturator with vacuum formed retainer material to close the palate gap. One month after the operation, the patient came to Oral Clinic RSUP Dr. Sardjito for evaluation. On the intraoral examination, there was a maxillary defect in Aramany’s class II. Resin acrylic obturator with hollow bulb was made as an obturator interim. The obturator insertion showed that the palate gap was tightly closed by the acrylic plate. In this case, the obturator interim successfully helps the patient bring back the function of speech, masticatory, and aesthetics

Abstract

Background: One of the success criteria in occular prosthesis is providing a prosthetic that is similar with the natural eye. Several methods for creating artificial iris are the use of iris from stock eyes, photo paper printing, painting with oil paints, and by implanting electronic components (dynamic iris). The oil painting method can produce an aesthetic 3D iris. However, when utilizing heat-cured acrylic resin to integrate the iris into the sclera, the use of a pressing machine when packing can distort the oil paint. Objectivess: The use of UV-resin material for iris fabrication can reduce the risk of distortion, reduce laboratory procedures, and produce an aesthetic iris. Case Report: A 28-year-old male came to Universitas Sumatera Utara dental hospital with complaint of the previous occular prosthesis felt loose and unaesthetic. Patient has been wearing the prosthesis for ±10 years. The patient wants a new occular prosthesis to replace the old prosthesis. Iris coloring is done with painting paper and oil paint, iris button is made with UV-resin using a pre-fabricated mold, then the iris is implanted into the sclera. The use of UV-resin for creating an iris requires only a few basic equipment and materials, has a quick-curing period, and facilitates iris position determination. Conclusion: Fabricating occular prosthetic with iris buttons made from UV-resin reduces the risk of laboratory failure and produces better esthetics.

Abstract

Background: The parameters for the long-term success of fixed dentures are retention and resistance. Fixed denture treatment for short abutments requires modification of tooth preparation to increase retention and resistance. The proximal area of the preparation can be modified to increase retention by adding grooves, boxes, and frustums. To increase resistance, proximal modifications in the form of adding grooves and boxes, and cervical angle of convergence modification can be used. Objectives: To analyze retention and resistance based on convergence angle and tooth preparation modification on short abutment. In abutment with ideal convergence angle, addition of grooves and boxes will causes the cement-restoration interface to increase. The frustrum-shaped preparation will convert the retention value from the shear strength of the cement material into the compressive strength of the cement material. In abutment with compromised convergence angle, proksimal modification in the form of grooves and boxes, as well as reducing the convergence angles in the cervical region will result in paralleling of axial walls and increase the resistance. Conclusion: In cases of a short abutment with an ideal convergence angle, the highest retention is obtained by modifying the proximal area with a frustum shape. Meanwhile, if the convergence angles are compromised, reducing the convergence angle in the cervical region would be the most effective method to improve the resistance.

Abstract

ABSTRACT Background: Loss of teeth and supporting tissues, which are functional components of the stomatognathic system, significantly affects masticatory function. Flabby ridges are one of the soft tissue anomalies in the edentulous. The main choice of treatment for edentulous patients with flabby ridges issues is a complete denture (CD). Flabby ridges cause problems with the retention and stabilization of the CD which causes displacement of the denture base during function. Lingualized and linear occlusion schemes were used to overcome the stabilization of CD by reducing stress distribution in the flabby ridge area when obtaining masticatory load. Assessment of stress distribution and displacement of CD can be analyzed using Finite Element Analysis (FEA). Objectives: This paper describes the use of FEA to assess the stress distribution and displacement of CD on flabby ridges by simulating axial and oblique forces in lingualized and linear occlusion schemes. Conclusion: The use of FEA for assessing stress distribution and displacement of CD in flabby ridges with multiple occlusion schemes has advantages in terms of accuracy and flexibility. Keywords: finite element analysis, occlusion schemes, flabby ridges, stress distribution, displacement of complete denture
