“…21 Therefore, recent studies have recommended a multivariate approach for analyzing the relationship between craniofacial structure and class III malocclusion. 22,23 Based on a discriminant analysis (DA), Stellzig-Eisenhauer et al 7 developed a formula to classify class III adults into a group that is treatable solely orthodontically and a group that requires orthog -nathic surgery. DA is a multivariate procedure that has Orthodontic Camouflage in Skeletal Class III Malocclusion: A Contemporary Review JOFR been especially designed to differentiate between 2 groups of subjects from the same population.…”

“…In most patients, there is no single feature responsible for the anomaly. [7][8][9][10][11][12][13][14] Those with class III malocclusion frequently show combinations of skeletal and dentoalveolar components. 15,16 Moreover, there are complex interactions of genetic and environmental factors that can act synergistically, in isolation, or in opposition.…”

Early orthopedic intervention can be effective in normalizing skeletal class III malocclusions if patients are treated in a timely manner. There are a large number of skeletal class III patients that either decline or cannot afford surgical treatment. The only alternative is 'Orthodontic camouflage' through comprehensive treatment with fixed appliances. The ultimate judgment as to whether orthodontic treatment alone, to camouflage a skeletal problem, would be an acceptable result, or whether orthognathic surgery to correct the jaw discrepancy would be required, must be made by the patient and parents. Class III camouflage logically would be the reverse of class II camouflage, based on retracting the lower incisors, advancing the upper incisors, and surgically reducing the prominence of the chin, in addition, rotating the mandible downward and backward, when the chin is prominent, can be considered a form of camouflage. Even though timing of orthodontic treatment has always been somewhat controversial, it is an agreement in the literature that prognosis is still obscure until growth is completed. A cephalometric analysis is needed to quantitatively record the severity of the class III malocclusion and to determine the underlying cause of the deformity. Although it is agreed that camouflage line of treatment is not an ideal line of treatment, but it serves its purpose very well in mild range of skeletal dysplasia's and in conditions where patient is either unwilling for orthognathic surgery or in cases were surgery is contraindicated.

ABSTRAKMaloklusi klas III true skeletal merupakan kasus yang sulit dirawat dan mudah terjadi relaps. Perawatan ideal kasus ini memerlukan tindakan bedah, namun apabila hal tersebut tidak memungkinkan maka dilakukan perawatan kamuflase. Reverse overjet, atau gigitan terbalik, tipikal mempunyai penyimpangan posisi insisivus atas dan bawah akibat malrelasi maksila dan atau mandibula. Tujuan artikel ini adalah menyajikan perawatan ortodontik kamuflase menggunakan teknik Begg pada maloklusi ini. Pasien perempuan umur 24 tahun mengeluhkan gigi depan berjejal dan tidak nyaman untuk mengunyah makanan. Diagnosis kasus adalah maloklusi Angle klas III, hubungan skeletal klas III dengan protrusif bimaksilar, incisivus atas dan bawah retrusif, pergeseran median line rahang atas ke kanan, disertai edge to edge bite anterior, cross bite posterior dan openbite posterior. Pasien dirawat dengan pencabutan gigi premolar kedua atas,dan premolar pertama bawah untuk mengatasi kondisi kasus tersebut. Kesimpulan dua tahun setelah perawatan, tampak sudut interinsisal berkurang, reverse overjet terkoreksi, edge to edge bite, cross bite dan openbite terkoreksi. Maj Ked Gi. Juni 2013; 20 (1) PENDAHULUANMaloklusi yang disebabkan oleh disharmoni skeletal sering kali mengakibatkan disharmoni wajah, keadaan tersebut akan mempengaruhi estetika, menimbulkan masalah pengunyahan dan bicara. Maloklusi klas III atau prognatisme, adalah hubungan tonjol mesiobukal gigi molar pertama rahang atas terletak sebelah posterior cekung mesio bukal gigi molar pertama rahang bawah. Gigi anterior rahang bawah lebih maju terhadap rahang atas. Maloklusi klas III dengan reverse overjet (gigitan terbalik) dapat disebabkan oleh kondisi rahang atas kecil dan rahang bawah normal, atau rahang atas normal dengan rahang bawah besar. Koordinasi yang kurang antara ukuran rahang atas dengan rahang bawah dapat juga mengakibatkan bukal crossbite baik unilateral maupun bilateral. Sudut gonial pada maloklusi klas III bervariasi dari tinggi ke rendah yang berhubungan dengan meningkatnya atau berkurangnya tinggi wajah maupun overbite. Lengkung gigi rahang bawah bervariasi dari rata-rata sampai di atas rata-rata, sedangkan variasi lengkung

“…[1][2][3][4] In adult patients without growing ability, orthognathic surgery is indicated for severe skeletal Class III malocclusion, but moderate Class III cases, so-called borderline cases, can be treated orthodontically if the patient declines surgery. [5][6][7] Several methods have been reported to treat such moderate Class III cases. [8][9][10][11][12][13] Extraction of lower teeth combined with Class III elastics can improve the dental occlusion for Class III patients, although its results are often compromised.…”

Objective: To evaluate the treatment effects of high-pull J-hook headgear on the lower dental arch in nongrowing Class III patients. Materials and Methods: Fourteen nongrowing Class III patients having an Angle Class III malocclusion and ANB angle of less than 1.0 degree, were treated with high-pull J-hook headgear to the lower arch. Using lateral cephalograms and plaster models obtained before treatment (T1), after active treatment (T2), and after the retention period (T3), the treatment outcome was analyzed.Results: The incisal edge of the lower central incisor moved a mean of 1.2 mm to the lingual and 1.7 mm to the occlusal between T1 and T2. The axis of the lower incisor inclined 4.0u to the lingual. The lower first molar cusp moved 1.5 mm to the distal and the root apex moved 2.0 mm to the mesial. Molar angulations were tipped 9.8u to the distal. The occlusal plane showed 4.5u counterclockwise rotation. The mean intermolar width increased 1.5 mm on average. Comparison of the records between T2 and T3 showed minimal changes. Conclusions: Distal movement of the lower dental arch using J-hook headgear was clearly demonstrated, confirming that the application of high-pull J-hook headgear to the lower arch was effective for improvement of the Class III occlusion.
