Evaluation of Ricketts' long-range growth prediction in Turkish children.

This study was conducted to evaluate Ricketts' long-range growth prediction in Turkish children. Cephalometric analysis was conducted at baseline and 7 years for 40 children (20 girls, 20 boys) who received no orthodontic treatment. Ricketts' long-range prediction was performed from baseline cephalograms and compared with actual growth 7 years later. Twenty-one cephalometric (12 angular and 9 linear) parameters were measured on actual and predicted tracings. The Pearson correlation coefficient was used to evaluate relationships between the "predicted" and "actual" measurements. Analysis was conducted on pooled data (males and females) and data by sex. There was a higher level of correlation for growth prediction in girls. Data indicate predictability in boys was greater for maxillary mandibular growth parameters. It was concluded that Ricketts' long-range growth prediction may be helpful in improving treatment planning. Further work on accurate soft tissue and hard tissue growth prediction is indicated.

[Orthodontic treatment in a cleft palate-cleft lip case with severe maxillary collapse].

The cleft lip and palate cases are the most frequently seen congenital deformities. Retardation of the maxillary development and collapse are the most significant characteristics in these cases. It is aimed to correct the functions like mastication, deglutition and speech which were disturbed due to anatomic deficiency and to obtain an acceptable occlusion and esthetics, by means of the therapy. As much as the preoperative orthopedic procedures applied just after the birth, the orthopedic and orthodontic appliances used in mixed and permanent dentition periods affect the prognosis in these cases. The purpose of the treatment in permanent dentition is to correct the malocclusion and to prepare the dentition to prosthetic restorations. In this article the orthodontic treatment of a case in permanent dentition, with cleft palate and lip characterized with severe maxillary collapse will be presented.

[Begg mechanics in treatment of congenitally missing lateral incisor].

The maxillary lateral incisors are the most frequently missing teeth after the third molars. The cases with congenitally missing lateral incisors are treated either by orthodontically closing the spaces or by space regaining for prosthetic restorations. Malocclusion is the most effective factor for selecting the treatment method. Besides the characteristics of the malocclusion and interdigitation, the colour, the shape, the size and the position of the canines effect the treatment planning. In particular, Class II Div. 1 and Cl. I anterior crowding cases are the most convenient cases for orthodontically closing the missing lateral spaces. In these cases besides the treatment of the present malocclusion the reshaping of the canines is aimed and these teeth are moved to lateral spaces. In this article the treatment of a Cl. II Div. 1 malocclusion case with congenitally maxillary missing lateral incisor with Begg technique will be presented. The changes and variations of the Begg mechanics applied for this case will be discussed.

[Alopecia areata is an idiopathic disorder in which there is a rapidly developing loss of hair that usually begins on the scalp].

In this article a case of alopecia areata which developed due to combined headgear is presented. It is aimed to warn the orthodontists about this rarely seen adverse effect of the extraoral orthodontic appliances.

[Long-term evaluation of the periodontal status in extraction treatment].

In this article the periodontal status of the 30 patients which were treated with Edgewise mechanics, by extraction of four first bicuspids is evaluated approximately 5 years later the active treatment. Comparison of the pocket depths between the teeth moved into extraction areas and the other teeth, is made. And also the pocket depths of the parallel and non-parallel teeth in the extraction area are compared. It is found that orthodontic treatment had no adverse effect on periodontal status in long term. But non-parallel teeth in the extraction area showed much higher values of pocket depth when compared to parallel teeth.

[Comparison of lower incisor positions after treatment and in postretention period, in Cl. I cases treated with Begg and Edgewise techniques].

The lower incisor positions have an important role in obtaining optimum occlusion and esthetics with orthodontic therapy. The aim of this study is to evaluate in longterm, the lower incisor positions of class I anterior crowding cases which were treated with Begg and Edge wise techniques. For this purpose lateral cephalometric radiographs of 20 Edge wise and 11 Begg cases which were treated by extraction of the four first bicuspids are evaluated. In all the cases T to NB (mm) T to NB (angle) and IMPA parameters examined before treatment, just after active therapy and in an average of 5 years postretention period. In cases which were treated with Begg mechanics, statistically important improvement is found in IMPA values after treatment. Lower incisors were stable in postretention period and there were no statistically significant differences when we compared the "after treatment" and "postretention" incisor positions in both treatment groups.

[Changes in the dental arch due to obligatory early extraction of first permanent molars].

The first permanent molars are the mo frequently extracted teeth due to caries. Early loss of these teeth which are known as "the ke of the occlusion" may lead to rotations, migrations, and elongations of the other teeth in the dental arches, and finally may cause occlusal disorders. This research is conducted on the patient whose first permanent molars need to be extracted due to profound caries and unrestorab material loss. By means of the lateral and panoramic radiographs taken just before the extraction and one year later, the local changes in the extraction and non-extraction segments are compared.

[Frankel III appliance].

FR III is a functional regulator appliance developed by Professor Rolf Frankel. This appliance is used in the treatment of Class III malocclusions. Optimum treatment results can be achieved when the appliance is used in the early mixed dentition period. The restricting effect of the buccinator and orbicularis oris muscles on maxillary skeletal development is prevented by means of lip pads and vestibular shields, thus maxillary development is stimulated. In this article philosophy, construction and clinical management of the FR III appliance will be described and two of our patients which are treated with this appliance will be presented.
