“…[ 26 ] The areas of the condylar cartilage involved in the chewing function are thicker and the condyle growth direction is posteriosuperior. [ 27 , 28 ] The treatment of condylar fractures depends on the age of the patient, the coexistence of other mandibular or maxillary fractures, whether the condylar fracture is unilateral or bilateral, the level and displacement of the fracture, and the status of dentition and dental occlusion. Therefore, it is considerable to evaluate the patient’s signs and symptoms of trauma and identify the most appropriate treatment modality.…”

BACKGROUND: Mandibular condyle fractures can be treated conservatively by intermaxillary fixation (IMF) or by open reposition and internal fixation. Although many studies have discussed for the optimal treatment method, the issue remains controversial. In this study, we aimed to compare conservative techniques in the mandibular condyle fractures. METHODS:Twenty four unilateral condyle fracture patients aged between 18 and 48 years were treated according to one of three different modalities. Bracketing, arch bar or mini screw was applied to all non-surgery patients to obtain IMF. Eight patients were treated with only IMF meanwhile eleven patients were treated with one or double-sided amplifier occlusal splint according to the status of fractured segments, in addition to IMF. Remaining five patients have undergone open reduction and fractured segments immobilized with mini plates. Pre-and post-operative images were recorded with a computerized tomography device. Clinical and radiological examinations were performed by orthodontists and surgeons at baseline and at 6 months of treatment. RESULTS:The condyle lengths of the patients with unilateral fracture after recovery were compared with the unaffected side. The length between the most protruding point of the condyle and the mandible was measured and the length difference was only 5.94 mm in patients who were treated by IMF. The length difference of patients who used brackets and splints was 3.36 mm (p<0.05). The length difference of patients who were repaired by plate screws was 1.80 mm (p>0.05). However, there was no statistically significant difference (p>0.05) between the groups in the IMF, occlusal splint and IMF and mini plate groups, between the trauma side and the opposite side. None of the patients developed ankylosis, open mouth, limitation of mouth opening, facial asymmetry, laterognathia, and retrognathia. The occlusion of the patients who were not known to have pre-trauma occlusions were directed, repositioned and provided an appropriate occlusion. CONCLUSION:The use of IMF with an occlusal splint is a more conservative and acceptable treatment modality than open reduction in selected cases.

Bentuk tulang pada komponen temporal dipengaruhi oleh faktor gizi, hormon dan fungsional karena adanya proses pergantian tulang secara terus menerus selama kehidupan yang disebut remodelling tulang.…”

Perubahan bentuk, ukuran eminensia artikularis dan fossa glenoidalis selama masa pertumbuhan perlu diketahui karena berperan penting dalam pergerakan sendi temporomandibular, sehingga membantu menegakkan diagnosa ada tidaknya kelainan pada tumbuh kembang. Variasi serta perubahan dapat dilihat dan diukur melalui radiograf panoramik. Tujuan penelitian ini untuk meneliti bentuk dan inklinasi eminensia artikularis serta kedalaman fossa glenoidalis berdasarkan usia ditinjau dari radiograf panoramik. Metode: Jenis penelitian deskriptif dengan teknik pengambilan sampel purposive sampling. Jumlah sampel didapat dengan menggunakan rumus Slovin, sebanyak 60 radiograf panoramik pasien RSGM Unpad, bulan Januari-Mei 2018 dengan rentang usia 5-30 tahun dibagi kedalam tiga kelompok usia berdasarkan usia pertumbuhan komponen temporal. Bentuk eminensia, inklinasi eminensia dan kedalaman fossa diukur menggunakan software ImageJ. Data diolah menggunakan Microsoft Excel ® untuk mengetahui nilai minimum, maksimum, nilai rerata, dan standar deviasi. Hasil: Mayoritas bentuk eminensia artikularis pada tiap kelompok usia adalah sigmoid. Rerata inklinasi eminensia artikularis adalah 42°, rentang usia 5-10 tahun, 44° pada rentang usia 11-20 tahun, dan 58° pada rentang usia 21-30 tahun. Rerata kedalaman fossa glenoidalis adalah 4,62 mm pada rentang usia 5-10 tahun, 5,71 mm pada rentang usia 11-20 tahun, dan 7,52 mm pada rentang usia 21-30 tahun. Simpulan: Bentuk mayoritas eminensia artikularis selama masa pertumbuhan adalah sigmoid, serta inklinasi eminensia artikularis dan kedalaman fossa glenoidalis nilai reratanya semakin meningkat seiring dengan pertambahan usia selama masa pertumbuhan. Eminensia artikularis dan fossa glenoidalis mengalami fase pertumbuhan aktif pada rentang usia 5-10 tahun, berjalan lambat pada rentang usia 11-20 tahun, dan mengalami penyempurnaan serta perkembangan pada rentang usia 21-30 tahun.Kata kunci: sendi temporomandibular; eminensia artikularis; fossa glenoidalis; usia; radiograf panoramik Morphology and inclination of articular eminence and glenoid fossa depth based on age observed in panoramic radiographABSTRACT Introduction: Changes in the morphology and size of the articular eminence and the glenoid fossa during the growth period need to be known because it plays an essential role in the movement of the temporomandibular joint, thus helping to diagnose the presence or absence of abnormalities in the growth and development. These variations and changes can be seen and measured through panoramic radiographs. The purpose of this study was to examine the morphology and inclination of the articular eminence and the depth of the glenoid fossa based on age observed from a panoramic radiograph. Methods: This research was descriptive with a purposive sampling technique. The number of samples obtained using the Slovin formula, which resulted in 60 panoramic radiographs of the patients from Universitas Padjadjaran Dental Hospital (RSGM Unpad), during the period of January-May 2018, with an age range of 5-30 years, di...

Biological Treatments for Temporomandibular Joint Disc Disorders: Strategies in Tissue Engineering

The temporomandibular joint (TMJ) is an important structure for the masticatory system and the pathologies associated with it affect a large part of the population and impair people’s lifestyle. It comprises an articular disc, that presents low regeneration capacities and the existing clinical options for repairing it are not effective. This way, it is imperative to achieve a permanent solution to guarantee a good quality of life for people who suffer from these pathologies. Complete knowledge of the unique characteristics of the disc will make it easier to achieve a successful tissue engineering (TE) construct. Thus, the search for an effective, safe and lasting solution has already started, including materials that replace the disc, is currently growing. The search for a solution based on TE approaches, which involve regenerating the disc. The present work revises the TMJ disc characteristics and its associated diseases. The different materials used for a total disc replacement are presented, highlighting the TE area. A special focus on future trends in the field and part of the solution for the TMJ problems described in this review will involve the development of a promising engineered disc approach through the use of decellularized extracellular matrices.
