Abstract

Defek telinga unilateral ataupun bilateral dapat disebabkan oleh berbagai faktor, diantaranya trauma, kelainan pertumbuhan, atau prosedur pengangkatan kanker. Kondisi ini akan mempengaruhi psikologis pasien karena telinga merupakan organ vital yang membentuk estetika wajah. Salah satu perawatan rehabilitasi pada defek telinga adalah dengan pembuatan protesa telinga. Tahapan penting dari pembuatan protesa telinga adalah mendapatkan cetakan yang akurat untuk membuat pola malam. Teknik pencetakan dalam pembuatan prothesa telinga diantaranya metode reversible hydrocolloid dengan sendok cetak malam, irreversible hydrocolloid dengan sendok cetak kaku dan metode pencetakan tiga lapis. Keunggulan teknik pencetakan tiga lapis adalah mudah di lakukan dan akurasi hasil pencetakan yang baik. Tujuan laporan kasus ini adalah mengaplikasikan teknik pencetakan tiga lapis dalam pembuatan prothesa telinga.Perawatan dilakukan pada seorang pria berusia 14 tahun yang mengalami defek kongenital telinga dextra (unilateral). Langkah pertama dalam pembuatan prothesa yaitu pencetakan telinga normal dan defek, dilanjutkan pembuatan pola malam dan basis protesa, kemudian tahap try in pola malam, processing silikon, dan insersi. Prosedur pencetakan telinga dengan teknik tiga lapis yaitu mengaplikasikan irreversible hidrocolloid pada regio post aurale (lapisan pertama), regio pra aurale, permukaan internal, (lapisan kedua), dan permukaan luar telinga (lapisan ketiga). Hasil pencetakan telinga dengan teknik tiga lapis adalah tiga lapisan irreversible hidrocolloid yang solid dan mudah untuk dipisahkan sehingga menjamin akurasi hasil pengecoran. Kesimpulan laporan kasus ini adalah teknik pencetakan tiga lapis dapat diaplikasikan dalam pembuatan prothesa telinga.ABSTRACTS: Triple Layer Impression Method For Auricular Prosthesis. An unilateral or bilateral auricular defect can be caused by several factors including trauma, congenital malformation or surgical removal of neoplasm. These condition will affect patient psycologic because ear is a vital part of facial aesthetic. One of rehabilitation care of auricular defect is an auricular prosthesis. Important stage of making auricular prosthesis is to obtain accurate impression to make wax pattern. Impression technique including method of reversible hydrocolloid with wax collar, irreversible hydrocolloid with rigid tray and triple layer impression method. The excellence of the triple layer impression technique are easy to do and accuracy of good impression result. The aim of this case report is to apply triple layer impression method in the making of auricular prosthesis. The treatment was done in 14 years old male patient with chief compain of congenitally defect of external dextra ear. First step of making auricular prosthesis is making an impression of defect area and opposite ear, making prothesa basis and wax pattern, try in the wax pattern, sillicone processing, and insertion the prothesa. Triple layer impression method was done in three step, first the impression material was injected to post aurale region (first layer), than injected to internal surface of ear (second layer). Subsequently, the third layer of impression material was partially filled into the tray and external surface of ear.The result of triple layer impression method in the making of auricular prosthesis is triple layer of solid irreversible hydrocolloid but separatable completly. Conclusion of this case report is the triple layer impression method is suitable for making an auricular prosthesis.

Abstract

Temporomandibular Joint Disorder (TMD) is a non-dental musculoskeletal disorder that has a complex and multifactorial etiology. The most frequent symptoms are pain in the masticatory muscles, in front of the ears, and in the temporomandibular joint (TMJ); this disorder can also be accompanied by clicking sounds and locking. This study aimed to present a case report of temporomandibular joint trauma following odontectomy. A 22-year-old patient came with some complaints, namely pain in the TMJ, a clicking sound when opening and closing the mouth, and limited mouth opening. The symptoms started when the patient underwent odontectomy on all the four third molars, causing tightness around the jaw, pain, and clicking. However, she did not seek any treatment for these conditions until the pain became worse and disturbed her activities. The patient had to deal with limited mouth opening and severe migraines up to twice a day. During an examination, the patient was able to open her mouth without pain only 25 mm in width, with a maximum mouth opening of 35 mm. The therapy was done by constructing a 4-mm stabilization splint and educating the patient on how to reduce the pain. In fact, 2 months after the treatment and the use of stabilization splints, her complaints of TMJ pain and clicking sounds decreased, her mouth opening increased, and the migraines never came back. In this case, non-invasive treatment as the first-line therapy in patients with disc displacement with reduction and arthralgia can reduce the joint pain symptoms, and some of the symptoms have even disappeared.

Abstract

Denture cleansing is one clinical parameter of successful denture wearing. This study aims to examine the effect of the type of denture cleanser on porosity and discoloration of acetal resin as a denture base. Twenty-four samples of acetal resin with 10 mm in diameter and 2 mm in thickness were divided into four groups. Porosity was measured using the wet and dry sample measurement method, and color value levels were measured using chroma meter for all samples. All of the samples were soaked into four types of denture cleanser: distilled water, alkaline peroxide tablets, 0.2% chlorhexidine gluconate, and 0.5% sodium hypochlorite for seven days, then the final porosity and color value level were assessed. The results showed that there were significant differences between groups in porosity and in color change of acetal resin (p < 0.05). Pearson’s correlation test showed that there was a positive correlation between the porosity level and discoloration level of acetal resin (p < 0.05). The research discovered that the type of denture cleaner has a significant influence on the porosity and color change of acetal resin. Sodium hypochlorite has the highest porosity and color change when compared to other cleansing agents.
