<![CDATA[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.]]>

<![CDATA[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 The extraoral strapping was retracted across the upper lip and feeding plate was grinded selectively to approximate the lip and alveolar segment concurrently.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]]>

<![CDATA[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]]>

<![CDATA[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.]]>

<![CDATA[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]]>

<![CDATA[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.]]>

<![CDATA[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]]>

<![CDATA[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.]]>

<![CDATA[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]]>

<![CDATA[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.]]>
