Late development of a mandibular second premolar
Bicakci, Ali Altug,Doruk, Cenk,Babacan, Hasan The Korean Association Of Orthodontists 2012 대한치과교정학회지 Vol.42 No.2
In this report, we present the case of a girl with delayed odontogenesis of a lower second premolar for which she was followed up for 8.5 years. Congenital absence of permanent mandibular second premolars was observed at the initial radiographic examination at 8 years and 1 month. One year later, during the treatment period, an unexpected odontogenesis of a right second premolar was diagnosed on follow-up radiography. The original treatment plan was revised and a new plan was successfully implemented. This unusual case showed that the orthodontist's clinical philosophy must be flexible because unexpected situations can arise, especially when treating growing patients.

Noncompliance screw supported maxillary molar distalization in a parallel manner
Nalcaci, Ruhi,Bicakci, Ali Altug,Ozan, Fatih The Korean Association Of Orthodontists 2010 대한치과교정학회지 Vol.40 No.4
상악 구치의 후방이동을 위한 구강 내 장치 중 환자의 협조를 필요로 하지 않는 방법은 제II급 부정교합의 개선에 성공적으로 널리 사용되고 있다. 본 연구는 스크류에 의해 지지되는 구강 내 후방이동 장치를 소개하고 그 효율성을 조사하고자 하였다. Angle Class II 부정교합으로 진단된 21명의 환자(여자 11명, 남자 10명; 평균 연령 14.9세)를 대상으로 하였다. 2개의 스크류를 incisive foramen 후방에 식립하고, 식립한 즉시 힘을 주어 상악 제1대구치의 후방이동에 사용하였다. 상악 구치를 후방이동시켜 제I급 구치관계를 얻기 위해 스크류에 의해 지지되는 구강 내 후방이동 장치를 사용하였다. 치료 전후 측모두부 방사선 사진과 3차원 모델 분석을 통해 골격 및 치아의 변화를 평가하였다. 연구결과 상악 구치는 평균 3.95 mm 후방이동하였고, 추가적인 고정원 소실 없이 제I급 구치관계를 확립하였다. 상악 대구치는 $1.49^{\circ}$ 후방경사 되었고, 회전된 정도는 좌우 각각 $0.74^{\circ}$, $0.54^{\circ}$으로 통계적으로 유의성 있는 변화를 보이지 않았다 (p > 0.05). 새롭게 고안된 장치는 스크류에 의해 지지되어 환자의 협조도를 요하지 않으며 특별한 고정원 소실 없이 구치의 치체이동을 통한 후방이동을 얻는 데 효과적인 것으로 판단된다. Objective: Intraoral noncompliance upper molar distalization techniques have gained in popularity and have subsequently found to be successful in Class II correction. The aim of the present study was to introduce a screw supported intraoral distalization appliance and investigate its efficiency. Methods: Twenty-one subjects (11 females, 10 males; average age of 14.9 years) with Angle Class II malocclusion participated in this study. Two screws were inserted behind the incisive foramen and immediately loaded to distalize the upper first molars. An intraoral screw supported distalization appliance was used to distalize the upper molars in order to achieve a Class I molar relationship. Skeletal and dental changes were evaluated using cephalometric and three-dimensional (3D) model analysis. Results: Upper molars were distalized 3.95 mm on average and a Class I molar relationship was achieved without any anchorage loss. The upper molars were tipped only $1.49^{\circ}$ and the upper right and left molars were rotated only $0.54^{\circ}$ and $0.74^{\circ}$ respectively which were statistically non-significant (p > 0.05). Conclusions: The newly designed screw supported noncompliance distalization appliance was found to be an effective device for achieving bodily molar distalization without any anchorage loss.

Objective: The purpose of this study was to evaluate the effects of chewing gum and low-level laser therapy in alleviating orthodontic pain induced by the initial archwire. Methods: Patients with 3–6 mm maxillary crowding who planned to receive non-extraction orthodontic treatment were recruited for the study. Sixty-three participants (33 females and 30 males) were randomly allocated into three groups: laser, chewing gum, and control. In the laser group, a gallium aluminum arsenide (GaAlAs) diode laser with a wavelength of 820 nm was used to apply a single dose immediately after orthodontic treatment began. In the chewing gum group, sugar-free gum was chewed three times for 20 minutes— immediately after starting treatment, and at the twenty-fourth and forty-eighth hours of treatment. Pain perception was measured using a visual analog scale at the second, sixth, and twenty-fourth hours, and on the second, third, and seventh days. Results: There were no statistically significant differences between the groups at any measured time point (p > 0.05). The highest pain scores were detected at the twenty-fourth hour of treatment in all groups. Conclusions: Within the limitations of the study, we could not detect whether low-level laser therapy and chewing gum had any clinically significant effect on orthodontic pain. Different results may be obtained with a higher number of participants or using lasers with different wavelengths and specifications. Although the study had a sufficient number of participants according to statistical analysis, higher number of participants could have provided more definitive outcomes.

A reliable method for evaluating upper molar distalization
Ruhi Nalcaci,Ayse Burcu Kocoglu-Altan,Ali Altug Bicakci,Firat Ozturk,Hasan Babacan 대한치과교정학회 2015 대한치과교정학회지 Vol.45 No.2
Objective: The aim of this study was to evaluate the reliability of measurements obtained after the superimposition of three-dimensional (3D) digital models by comparing them with those obtained from lateral cephalometric radiographs and photocopies of plaster models for the evaluation of upper molar distalization. Methods: Data were collected from plaster models and lateral cephalometric radiographs of 20 Class II patients whose maxillary first molars were distalized with an intraoral distalizer. The posterior movements of the maxillary first molars were evaluated using lateral cephalometric radiographs (group CP), photocopies of plaster models (group PH), and digitized 3D models (group TD). Additionally, distalization and expansion of the other teeth and the degrees of molar rotation were measured in group PH and group TD and compared between the two groups. Results: No significant difference was observed regarding the amount of molar distalization among the three groups. A comparison of the aforementioned parameters between group PH and group TD did not reveal any significant difference. Conclusions: 3D digital models are reliable to assess the results of upper molar distalization and can be considered a valid alternative to conventional measurement methods.
