Manipulasi basis gigi tiruan nilon termo plastic dengan teknik injection moulding akan menghasilkan nilon sisa (spru) dan nilon sisa dapat dimanfaatkan kembali dengan cara daur ulang dikarenakan ikatan linear dari nilon sehingga material ini dapat dipanaskan kembali. Namun, daur ulang pada nilon sisa akan menyebabkan penyerapan air semakin bertambah dan hal ini akan berdampak pada nilon sebagai basis gigi tiruan. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan nilon murni pada nilon daur ulang terhadap penyerapan air basis gigi tiruan nilon termoplastik. Rancangan penelitian ini adalah eksperimental laboratoris. Sampel pada penelitian ini adalah nilon termoplastik berbentuk silindris berukuran diameter 15 ± 1 mm dan ketebalan 0,5 + 0,1 mm dengan jumlah sebanyak 27 sampel untuk 3 kelompok. Hasil uji nilai penyerapan air di analisis dengan uji ANOVA serta uji LSD. Hasil penelitian ini menunjukkan adanya perbedaan yang bermakna antara nilon murni dengan nilon daur ulang (p = 0,001) dan juga antara nilon daur ulang dengan kombinasi 60% nilon murni dengan 40% nilon daur ulang (p = 0,004), tetapi tidak ada perbedaan antara nilon murni dengan kombinasi 60% nilon murni dengan 40% nilon daur ulang dengan nilai (p = 0,629). Sebagai kesimpulan, penambahan 60% nilon murni pada 40% nilon daur ulang menghasilkan nilai penyerapan air yang sama baiknya dengan nilai penyerapan air pada nilon murni.

Loss of eye have physiologic and social impact on patients, especially in pediatric patients. To overcome this problem ocular prosthesis can be made similar with the color, shape, size and movement of the patient’s eye, so the ocular prosthesis can look like natural eye. The various methods, techniques and concepts documented in this case re-port with modifications to the physiologic impression and making of iris buttons aim to get the better movement of the prosthesis and 3D profile of the iris. A 6-years-old female patient came to the USU Dental Hospital to fabricate a new eye prosthesis. The patient had a medical history of retinoblastoma at the age of 2 years and had enucleation surgery. The eye is rehabilitated with fabrication of a custom ocular prosthesis with modifications on physiologic im-pression and iris button making. Modifications to physiologic impression and modifications to the fabrication of iris buttons will provide movement, shape and 3D effects of iris that are better than stock eye prosthesis. It is concluded that custom ocular prosthesis with modification on physiologic impression provide a better and more natural move-ment. While modification on making iris button using customized iris button cuvette will facilitate the process of ma-king iris button.

Enucleation leads to contracture of orbital tissue accompanied by reduction in volume and forniceal depth, which results in an inability to sustain a prosthesis. Shallow inferior fornix in contracted eye socket compromises adaptati-on, retention, stabilization and duplication of palpebral opening similar to natural eye in terms of size, support, con-tour and convexity make fabrication of custom ocular prosthesis become challenging. Hence, the present article describes the use of ocular prosthesis as conformer to obtain better appearance and enlarge orbital dimension in contracted socket. A 21-year-old male came to Dental Hospital Universitas Sumatera Utara with a complaint of un-aesthetic face appearance due to enucleation of left eye in the last 5 years old subsequent to trauma by sharp blades. The patient had already used an ocular prosthesis but lost it 6 years ago and didn’t used it until now. In cli-nical examination, the anopthalmic socket had good posterior wall mobility and absence of infection but, mild con-tracted socket (Grade 1) with shallow inferior fornix depth was examined. In this case, ocular prosthesis provides aesthetics as well as expanding the lid anteriorly, conjunctiva and fornix posteriorly that were successfully obtain-ed by performing functional impression using imprinted waxed up. This results in a favorable peripheral eye seal.

Loss of eye does not only affect facial esthetics but also psychological health of the patient and leads to social disa-bility. A custom-made ocular prosthesis is a good alternative to promote physical, psychological and esthetically plea-sing appearance that can improve social acceptance of the patient. A 5-years-old female patient and 18-years old male patient were reported to Dental Hospital USU with the chief complaint of loss of an eye, making them often in-sulted by schoolmates, while the male patient lost confidence on socializing around. In these cases, ocular prosthe-ses with modification of custom tray was made by using a putty index obtained from wax pattern to produce a better fitting ocular prosthesis so it expected to be retentive as to produce comfort and increase patient confidence. Con-tact between ocular prosthesis and tissue bed is necessary to evenly distribute the pressure obtained with proper im-pression technique. This technique ensures a good fit of the custom tray thereby produce accurate adaptation to the tissue surface can increase the movement of the prosthesis and provide a good natural esthetic outcome. Post evi-sceration patients need psychological support to restore confidence and self-esteem in today's cosmetics challenging world. For these cases, patients’ self-confidence was restored and socializing as before without any embarrassment.

Ocular prosthesis for post evisceration socket often has feeble adaptation to the surrounding tissue due to high sensi-tivity. Excessive pressure given by impression technique would lead to irritably intaglio and bulky palpebral contour of the prosthesis. This article describes a modified method of functional impression which made it easier not only to record the tissue bed surface of the defect but also to get the right contour of the palpebral surface at the same time. A 60-year-old male came to Dental Hospital Universitas Sumatera Utara with evisceration defect as a result of traumatic injury 40 years ago. He complained a facial disfigurement that made him formidable with social interacti-on. Pressureless impression combined with calibrated tray was planned for the patient. Light body PVS material was injected into the socket under slight pressure and the conformer made from visible light cure acrylic resin was in position as a tray. Vertical and horizontal lines marked in the conformer calibrate with the facial marking as a gui-dance for 3-D position. The method is intended to get the fast, accurate position offering the patient ocular prosthesis with great comfort as well as to provide facial contours that improve the patient's psychological and physical outlook.

Patient with loss of eye demands natural ocular prosthesis for self-esteem and social intercourse. Iris texture and coloring technique are crucial procedure to recreate natural iris like the remaining eye. The purpose of this paper is to explain sculpting method using composite-resin to achieve natural iris pattern. A 29-year-old male came to Dental Hospital Universitas Sumatera Utara with chief complaint of demanding new ocular prosthesis because old ocular prosthesis had been used for 12 years, iris position was not good and not aesthetically pleasing. The modification is the use of a 12 mm diameter iris base made from light-cured composite resin then a thin layer of composite resin is placed evenly and texture of iris is sculpted directly on composite resin according to the designed pattern and then being light-cured again. Then coloring with acrylic paint according to the color of patient's left iris. The technique for du-plicating iris is highly dependent on the operator's ability, both in color selection and iris patterning. The use of com-posite resin make it easier to get a good texture of iris pattern so as to facilitate coloring process with the ultimate goal of achieving an aesthetically pleasing ocular prosthesis. Patient was satisfied with his new ocular prosthesis.

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

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.
