Tindakan Alveolar Bone Grafting (ABG) adalah salah satu prosedur yang paling penting pada penanganan pasien ini. ABG sangat mempengaruhi erupsi dari gigi geligi dan stabilitas rahang atas pada pasien dengan celah bibir dan langit - langit unilateral. Hal ini menimbulkan banyak keluhan pada pasien sendiri maupun keluarganya.Tujuan : Penelitian ini mengevaluasi pengaruh penatalaksanaan alveolar bone grafting sesuai protap di RSAB Harapan Kita Jakarta terhadap besarnya nilai deformitas nasal secara antropometri melalui photogrammetri, serta melihat hasil akhir estetik yang proporsional pasca tindakan alveolar bone grafting sebagai salah satu cara untuk mengevaluasi protokol tata laksana yang tetap terhadap pasien - pasien celah bibir dan langit - langit.Metode : Pasien celah bibir dan langit - langit unilateral pasca alveplar bone grafting dilakukan evaluasi deformitas nasal secara antropometri melalui photogrammetri dari 3 aspek yaitu: anterior,lateral dan basal.Hasil : Pengukuran antropometri secara photogrammetri dari 3 aspek dengan landmark sebanyak 14 titik dan item jarak sebanyak 11. Evaluasi terhadap upper lip length, upper lip projection dan nostril sill elevation pada sisi non cleft dan sisi cleft. Dari uji t-test pengukuran pada upper lip length dan upper lip projection menunjukkan hasil yang bertambah secara signifikan. Dilakukan uji koreksi dengan Fisher Exam Test dengan nilai 1.Diskusi : Hasil penelitian menunjukkan adanya kesesuaian pengukuran antropometri secara photogrammetri hasil operasi pasca bone graft pasien celah bibir dan langit - langit unilateral dan menunjukkan hasil akhir estetik yang proporsional dengan nilai yang kecil.Kesimpulan : Dari penelitian ini dapat disimpulkan bahwa protokol tata laksana pasien celah bibir dan langit - langit di Unit Celah Bibir dan Langitan RSAB Harapan Kita Jakarta memberikan hasil yang memuaskan terhadap pasien dan keluarganya dengan melihat terjadinya deformitas pada nasal dan bibir yang tidak begitu besar serta dihasilkannya estetik yang proporsional.

Background : Rehabilitation of patients with unilateral cleft lip and palate requires multi steps and coordination of multidisciplinary science and connecting to produce an optimal result. Alveolar Bone Grafting (ABG) is an important procedure in the treatment of this patients. ABG extremely to influence of the erupting teeth and the stability of the maxilla in patients with unilateral cleft lip and palate. Many complains appearance about this for patient either the family.

Aims : To evaluated the effect of alveolar bone grafting procedure at Cleft Center Harapan Kita General Hospital in order to see the broad value of nasal deformity from anthropometry with photogrammetry and aesthetic proportional patients with unilateral cleft lip and palate. To make a decision that the correct protocol for the treatment in this case.

Method : Patients with unilateral cleft lip and palate post alveolar bone grafting procedure received evaluating of nasal deformity investigated with anthropometry by photogrammetry from 3 aspect: anteriorly, laterally, and basal.

Result : Anthropometry measurement by 3 aspect of photogrammetry with landmark to consist of 14 point and 11 distance item. Evaluation of upper lip length, upper lip projection, and nostril sill elevation at cleft site and non cleft site. t-test showing that the value of upper lip length and upper lip projection is significantly increase. We do the correction test with Fisher exam test with value is 1.

Discussion : This study is showing an adaption between anthropometry measurement with photogrammetry of patients with unilateral cleft lip and palate with the result after post alveolar bone grafting procedure and aesthetic proportional as final result with small value.

Conclusion : We conclude that treatment protocol the patients with unilateral cleft lip and palate at Cleft Center Harapan Kita General Hospital to give some satisfied to patients itself and the family based on a small of nasal deformity at lip and the final result of aesthetic proporsional."

"[Latar Belakang: Magnesium merupakan biomaterial logam yang berpotensi digunakan sebagai material implan tubuh yang dapat terdegradasi. Syarat magnesium dapat digunakan sebagai material implan biodegradasi adalah laju degradasi magnesium harus memiliki kekuatan mekanis yang cukup dalam jangka waktu tertentu, sampai terjadi penyembuhan tulang, kecepatan resorbsi yang sesuai dengan kecepatan penyembuhan tulang. Aplikasi magnesium sebagai implan yang terdegradasi terhambat karena tingkat tinggi degradasi lingkungan fisiologis. Dengan adanya sifat biodegradasi magnesium maka diperlukan cara bagaimana mencegah atau menekan kecepatan laju biodegradasi sehingga dapat disesuaikan dengan proses penyembuhan tulang. Beberapa penelitian tentang magnesium telah dilakukan untuk mengatasi keterbatasan tersebut, antara lain dengan prosedur Equal Channel Angular Pressing ( ECAP), merupakan salah satu prosedur dari grain refinement yang dapat menurunkan laju degradasi dan meningkatkan sifat mekanis magnesium. Tujuan: Menganalisa sifat mekanis magnesium ECAP dalam perendaman dalam larutan DMEM. Metode: Sifat mekanis magnesium ECAP dianalisis setelah dilakukan perendaman dalam larutan DMEM dengan menggunakan masing-masing sepuluh sampel magnesium ECAP untuk uji bending dan sepuluh sampel magnesium ECAP uji keuletan. Sifat mekanis di analisis menggunakan nilai bending pada uji bending dan nilai keuletan pada uji keuletan. Hasil: Terdapat pengaruh waktu perendaman terhadap nilai bending magnesium ECAP, nilai keuletan magnesium ECAP dan penurunan nilai bending juga nilai keuletan magnesium ECAP pada perendaman dalam larutan fisiologis DMEM., Background: Magnesium is a metal biomaterials that could potentially be used as an implant material which can be decomposed body. Requirement of magnesium can be used as an implant material is the biodegradation rate of degradation must possess sufficient mechanical strenght in a certain period of time until the healing bone resorption speed corresponding to speed bone healing, generally magnesium has a rapid rate of degradation, it is undesirable magnesium deficiency. Application of magnesium as the implant is degraded hampered by high levels of physiological environmental degradation. With the biodegradation rate of speed so it can be adapted to the bone healing process. Several studies on magnesium have been made to overcome these limitations. Among others, the ECAP procedure which is one of the grain refinement procedure that can decrease the rate of degradasi and improve the mechanical properties of magnesium. Objective: To analyze the mechanical properties of magnesium ECAP in DMEM solution immersion. Methods: Mechanical properties of magnesium ECAP analyzed after immersion in DMEM solution by using each of the ten samples of magnesium ECAP for bending test and ten samples of magnesium ECAP for ductility test. Result: There is the effect of immersion time on the value of ECAP bending magnesium, magnesium ECAP ductility value and impairment bending ductility also magnesium ECAP on immersion in physiological solution of DMEM.]"
