ORTHODONTIC TREATMENT WITH SKELETAL ANCHORAGE SYSTEM

The correction of Class I malocclusion with bimaxillary dental protrusion and unilateral free end right upper ridge in adult patient is one of difficult biomechanical case in orthodontics. Because this case needs proper anchorage for upper incisor retraction with missing teeth in the right posterior segment Purpose: This article presented a case of an adult patient with severe bimaxillary protrusion treated with Skeletal Anchorage System (SAS). Case: A female patient, 36 year old complaining for the difficulty of lip closure due to severe bimaxillary protrusion with incompetence lip. Case Management: Firstly correction of the maxillary and mandibular incisor proclination were done by extraction of the mandibular first premolar, the maxillary second premolar on left side and finally placement of miniplates implant in the zygomatic process on right side as an absolut anchorage. Conclusion: The results of this treatment indicated that Skeletal Anchorage System (SAS) can be considered as an effective therapy choice for corection bimaxillary protrusion with unilateral free end ridge.

MINI SCREW AS TEMPORARY ANCHORAGE DEVICES IN BIMAXILLARY PROTRUSION AND FREE END MANDIBULAR POSTERIOR TEETH

Orthodontic treatment on the bimaxillary dental protrusion is to reduce the proclination of the mandibular and maxillary anterior teeth. Lost of posterior teeth (free end) often occured in adult cases and required additional skeletal anchorage. Purpose : This article is to present a case of an adult with bimaxillary protrusion and free end on mandibular treated with mini screw implant orthodontic as temporary anchorage.Case : A female patient, age 38 years old cmnplaining about the difficulty of lip closure due to severe bimaxillary protrusion Case Management: The patient was treated using standart edgewise orthodontic appliance with mini screw implant as temporary anchorage devices to help this movement without worried about loss anchorage. Concluison : The result of this treatment indicated that mini screw can be considered an effective therapy choice .

ORTHODONTIC TREATMENT OF CLASS I MALOCLUSION WITH SEVERE BMAXILLARY PROTRUSION

The correction of Class I malocclusion with bimaxillary dental protrusion in adult patient is one of difficult biomechanical in orthodontics.Convexity of the face is resulting from protruded and proclined upper and lower incisor caused poor facial aesthetic. Purpose :This article is to present a case of an adult patient with severe bimaxillary dental protrusion who was treated with standart edgewise technique. Case :A female patient, age 26 complained about the difficulty of lip closure due to severe bimaxillary dental protrusion with incompetence lip. Case Management :Correction of the maxillary and mandibular incisor proclination is corrected by extraction of the bilateral maxillary and mandibular first premolar.Conclusion :The results of this treatment indicated that ectraction of four first premolars and retraction of the anterior teeth using standart edgewise technique can be considered an effective therapy choice for corection bimaxillary dental protrusion.

ORTHODONTIC CAMOUFLAGE TREATMENT OF SKELETAL CLASS III MALOCCLUSION

Class III malooclusion can be defined as a skeletal facial deformity characterized by a forward mandibular position with respect to the cranial base and or the maxilla. There are three main treatment options for skeletal class III malocclusion : growth modification, orthodontic camouflage and orthognathic surgery. This article presented a case of an adult patient with skeletal class III malocclusion treated with orthodontic camouflage treatment. A female patient, 21 year old with concave facial profile complaining for the difficulty of occlusion due to anterior crossbite and openbite. Case Management : Extraction of the poor conditioned mandibular first molars to gain space for anterior segment retraction, placement of lingual arch bar to prevent anchorage loss and class III intermaxillary elastics for dentoalveolar compensation by proclining maxillary incisor and retroclining mandibular incisors (orthodontic camouflage). Conclusion: The results of this treatment indicated that orthodontic camouflage can be considered an effective therapy for corection of skeletal class III malocclusion.

THE TREATMENT OF ANTERIOR OPEN BITE WITH EXTRACTION OF FIRST PREMOLARS

The anterior open bite malocclusion is one of the most difficult dentofacial deformities to treat. Open bite is an occlusal characteristic where the upper and lower teeth are not in contact and vertical overlap does not exist. A major etiologic factor that reportedly contributes is various habits such as tongue thrust. These factor affecting the development of the anterior dentoalveolar complex, inhibting the normal eruption of teeth and flaring of the upper anterior teeth. Extraction of the first premolar are the most commonly considered procedures for the treatment of anterior open bite associated with crowding. A 30 years old female presented class I dental and class III skeletal malocclusion with retrognathic maxillary, anterior open bite, crowding and tongue thrust habit. In these patients the anterior open bite is closed with the extrusion of the anterior segment by extracting the first premolars. This treatment alternative works very well in patients with occlusal planes that diverge anteriorly from the first premolar. The mechanics are easier when the anterior teeth are flared than retraction of the incisors will produce lingual tipping of the incisor crowns to close the bite. After 2 years treatment anterior open bite had been corrected to normal position and profile view shows facial change with mandibular autorotation and reduction of the anterior facial height

EVALUATION OF CLASS II DIV 1 MALOCCLUSION USING ICON AND IT'S RELATIONSHIP TO THE TREATMENT DURATION AND THE APPOINMENT FREQUENCY

Class II Angle division 1 malocclusion is type of malocclusion with difficult complexity to handle. ICON (Index of Complexity, Outcome and Need) is an occlusal index that can be used to determine treatment needs, complexity, outcome acceptance and degree of improvement of malocclusion class II division 1. The aims of this study is to evaluate assessment standards for the treatment outcome and its relation with the treatment need, appointment frequency and duration of treatment in the case of class II division 1 malocclusion. The sample of this study are study model before and after patients class II division 1 malocclusion treated at the Orthodontic Specialist Clinic Faculty of Dentistry Airlangga University in 2005 - 2010. The study models before treatment were assessed by ICON for treatment needs and complexity of the case. Further progress model after treatment were then assessed by ICON for outcome acceptance and degree of improvements. This study calculated the duration of treatment and the frequency of appointment as well.
The results of the study showed that all of the samples, need the orthodontic treatment and 40% of them categories as difficult cases. The treatment results showed that the acceptable and degree of improvement are almost 100%. There is a relationship between the treatment needs, and frequency of appoinment compared to the outcome of treatment with significance different on both results (p<0.05).

THE EFFECT OF BODY MASS INDEX TO THE MAXILLA ARCH HEIGHT AND WIDTH

The dental arch form is of prime importance to the dentists. It is useful in orthodontic procedures for predicting succesfully treatment and knowing evolutionary changes in arch and their variation. Body mass index is defined as the ratio of weight to squared height, has been popularly used as a nutrision parameter and growth. The aim of this study was to examine the effect of body mass index to the maxilla arch height and width.
This experimental study was held in Orthodontic laboratory. Children were examined at age 8-14 years, standardized heights and weights were obtained to calculate body mass index. The maxilla arch height and width measurements used the first treatment cast (study model) with Raberin Technique. The measurements were made after noting certain reference points on the study models and measure by using calipers. Manova were used to assess the effect of body mass index to the maxilla arch height and width .
The maxilla arch height and width were significantly (p< 0.05) different in different body mass index and the measurements for maxilla arch height and width in normal weights was the greatest.
The findings suggest that body mass index has effect to the maxilla arch height and width.

A COMPARISON OF THE IOTN AND ICON

The demand of orthodontic treatment for malocclusion is increasing in Indonesia. Malocclusions describe a spectrum of a deviation from the ideal to very severe anomalies. Dentist may have differing views of what should be. The IOTN is a useful tool for those interested in research into epidemiology of malocclusion. IOTN has two parts: the Aesthetic (AC) and Dental Health (DHC) components. The ICON index has been developed recently and claims among other things, to evaluate orthodontic treatment complexity. The index comprises five weighted measurements, and some of its structure to IOTN. The sum of the weighted scores is interpreted using cut-off values and score ranges to indicate the treatment need, complexity and degree of improvement. It is claimed that using ICON to make these assessments is more efficient than IOTN because it requires only a single measurement protocol. This literature study explain that the ICON provides an acceptable alternative to IOTN.
