Pretreatment and post treatment records were evaluated. Correction of malocclusion by changing direction of the mandibular development, adaptive bony development of the condyle, vertical development in posterior region, an increase in ramus length, a decrease in the lower facial height were observed in this report. The results of functional treatment of three appliances had different effect mechanisms.

Bu calismanin amaci tel capinin, materyal ozelliklerinin (yuzey puruzu ve stiffness) ve tel ile braket arasindaki acinin surtunme kuvvetleri uzerine etkisini ortaya koymaktir. Elde edilen sonuclara gore; Surtunme direnci butun tel materyallerinde aci arttikca artmaktadir. Ayni materyalden tellerde ise ince capli teller kalin caplilara oranla daha az surtunme gostermektedir. Yuzey puruzu tel ile braket arasindaki surtunme uzerinde etkin bir faktor olarak gorulmektedir. Iyon implantasyonu metoduyla yuzeyi sertlestirilen ve puruzleri azaltilan Slippery NiTi ayni capli SS, NiTi ve TMA tellerden daha dusuk surtunme degerleri gostermektedir. Cok sarimli teller tum aci degerlerinde SS, NiTi ve TMA tellere gore dusuk surtunme direncine sahiptir.

Zinc polycarboxylate and glass ionomer cements are the primary materials used in band cementing. In this study, we evaluated the re-cementing frequencies, enamel demineralization and the degree of cement remains of the bands cemented with glass ionomer and zinc polycarboxylate cements. We have concluded that given the retentive properties and enamel decalcification degree, the glass ionomer cements are to be preferred by the orthodontist.

SN-Go-Gn, Gonion, ANS-PNS/Go-Gn angles and S-Go, N-Me, S-Go/N-Me measurements from lateral cephalometric films were used as identification parameters. Seven horizontal, five vertical and five angular cephalometric measurements were made in order to determine the position of the hyoid bone. SN plane was used as the reference plane. Results were evaluated through "t" test. No significant relation was found between hyoid bone position and gender. When gender distinction was disregarded, and the group with normal facial development was compared with the hyperdivergent group, statistically significant differences were observed for CVTH distan...

Forty-eight skeletal Class I, 60 Class II, and 44 Class III subjects with similar skeletal characteristics were included in this study. Analysis of variance was performed to compare the mean ratios of Bolton analysis as a function of the Angle classification and sex. To determine the prevalence of tooth size imbalances among the three groups of occlusions and the two sexes, chi-square tests were performed. To determine the correlation of tooth size imbalances with certain dental characteristics, Pearson's correlation coefficients were calculated. No statistically significant differences were determined for the prevalence of tooth size discrepancies and the mean values of Bolton's anterior and overall ratios among the occlusal groups and sexes. Bolton's anterior ratio discrepancies had significant correlations with midline shifts (P &l...

The study group consisted of 109 patients (52 boys, 57 girls) with a mean chronological age of 13.6 years for boys and 14.7 years for girls. Insertion of either a 0.014 or 0.016 inch wire was by random selection. Following insertion of the archwires, a questionnaire comprising a total of 49 questions was given to the patients. They described the time of initial pain in the first question, answered the next 24 questions as 'yes' or 'no', and used a visual analogue scale for the final 24 questions. No significant differences were found in terms of gender, in the perception period of initial pain as regards the areas affected within the mouth or the effect of pain on daily living when the 0.014 and 0.016 inch wire groups were compared at 6 hours, 1, 2, 3, 4, 5, 6 and 7 days. At 24 hours, which was found to be statistically significant, more pain relief was used in the 0.014 inch archwire group. The results show that in both groups, initial pain was perceived at 2 hours, peaked at 24 hours and had decreased by day 3.

Despite the many advantages of pendulum appliances, the maxillary incisors and premolars tend to shift mesially as the maxillary molars move distally. The purpose of this study was to investigate anchorage loss in patients treated with palatal osseointegrated implants combined with pendulum springs. Methods: Pretreatment and posttreatment lateral cephalometric films of 30 consecutively treated patients were examined. One group (n ϭ 15) had been treated with conventional pendulum appliances, and the other group (n ϭ 15) was treated with palatal osseointegrated implants combined with pendulum springs. Results: In the pendulum group, significant distal tipping of the maxillary first molars and mesial tipping of the maxillary premolars were noted. Distalization of the maxillary first molars, mesialization of the maxillary first premolars, and proclination of the maxillary left central incisor were significant in the linear measurements. In the implant group, the distal tipping of the maxillary first molars and first premolars and the increases in SNGoGn, FMA, Na Me, and Na ANS were significant. Intergroup comparisons showed that changes in the maxillary first premolars, maxillary central incisors, and vertical measurements were significant. Conclusions: The use of palatal osseointegrated implants is reliable and provides absolute anchorage.

On acik kapanis anomalisi bulunan ve yas ortalamasi 9.83 olan 25 hasta arastirma kapsamina alinmistir. Hastalarin ilk randevularinda lateral sefalometrik ve el-bilek filmleri alinmistir. Hastalara hicbir ortodontik tedavi uygulanmadan 2 yil boyunca 2 ayda bir kontrole cagrilmislardir. 2 yilin sonunda hastalarin 12'sinde acik kapanis kendiliginden duzelirken 13'unde degisiklik olmamistir. 2. yilin sonunda tekrar sefalometrik filmler alinmistir. Spontan olarak acik kapanisin duzeldigi gruptan elde edilen sonuclar vertikal gelisimin azaldigini ve mandibulanin one ve yukari rotasyonunun saglandigini gostermistir. Hicbir ortodontik mudahalede bulunulmadigi icin bu degisim gelisimin etkisi ile saglanmistir. Diger grupta mandibulanin posterior rotasyonu ve vertikal gelisim devam etmektedir. On acik kapanis olgularinin pubertal donem oncesinde belirli surelerle kontrole alinmasi, anomalinin ortodontik tedavi gerektirmeksizin ge...

Lateral sefalometrik olcumlerde SNA, SNB ve ANB, Go-Gn-SN acilari tanimlayici olcum olarak kullanilmistir. Hyoid konumunu belirlemek icin ise 7 adet horizontal, 5 adet vertikal ve 5 adet acisal olmak uzere toplam 17 adet sefalometrik olcum yapilmistir. SN duzlemi referans duzlemi olarak kullanilmistir.Yapilan olcumlerin istatistiksel olarak degerlendirilmesinde Mann-whitney testi kullanilmistir. Sinif I grubu ile Sinif II D 1 gruplari karsilastirildiginda At-H, H-CVT ve H-OP, A-H, N-H, H-PTR degerleri, Sinif I grubu ile Sinif III gruplari karsilastirildiginda, At-H ve H-OP, A-H, N-H, H-PTR, degerlerinde istatistiksel olarak anlamli farklilik belirlenmistir. Hyoid kemiginin Sinif II D1 anomalisinde normalden daha geride, Sinif III anomalisinde ise daha onde konumlandigi gozlenmistir.
