Abstract (2. Language): 
Objective: The aim of this study is to evaluate the thicknesses of the upper and lower alveolar regions after extraction and nonextraction fixed treatment. Method: For this purpose, cephalometric films of 61 patients treated with four premolar extraction (n=31) and nonextraction (n=30) were evaluated. Palatal and labial alveolar thicknesses of the incisor teeth were measured at the level of the apical and coronal third of the roots. The differences between the groups were assessed by Mann-Whitney tests or student‟s t test and intragroup differences were calculated by Wilcoxon signed rank test or paired t test considering whether normal or abnormal distributed data. palatal side of the alveolar bone thickness in both groups. The alveolar bone palatal to the upper incisors were decreased, while the lingual side of the lower incisors did not change in nonextraction group. Results: The bone thickness labial to the upper anterior incisors did not change while the palatal side of the incisors were decreased significantly at the coronal and apical levels after both treatment procedures. Maxillary bone thickness decreased significantly in only nonextraction group. The alveolar bone thickness lingual to the lower incisor teeth decreased significantly at the coronal and apical levels in extraction group, while lingual bone decreased at the apical level in nonextraction group. The alveolar bone thickness labial to the lower incisors did not change in both extraction and nonextraction groups. B-B' width which is the narrowest region of the symphysis region decreased in only extraction group. Discussion: All anterior alveolar thicknesses decreased or remained stable after extraction and nonextraction treatment. Similar changes were observed in especially

Amaç: Bu çalışmanın amacı dört premolar çekimli ve çekimsiz olarak tedavi edilmiş vakalarda alt ve üst anterior alveoler bölge kalınlıklarını değerlendirmektir. Yöntem: Bu amaçla dört premolar çekimli olarak (n=31) ve çekimsiz olarak tedavi edilmiş (n=30) 61 hastanın sefalometrik filmleri değerlendirilmiştir. Keser dişlerin köklerinin palatal ve labial alveoler kalınlıkları koronal ve apikal üçte birlik kısım hizasından ölçüldü. Verilerin normal dağılım gösterip göstermemesine göre gruplar arası farklılıklar Mann-Whitney veya bağımsız t testi ile, grup içi farklılıklar da Wilcoxon işaret testi veya eşleştirilmiş t testi ile değerlendirildi.Sonuçlar: Her iki tedaviden sonra da üst keserlerin labial tarafındaki kemik kalınlığı değişmezken, palatal taraftaki kalınlık hem koronal hem de apikal seviyede önemli ölçüde azalma göstermiştir. Maksiller kemik kalınlığı sadece çekimsiz grupta önemli bir azalma göstermiştir. Alt keserlerin lingual tarafındaki alveoler kemik kalınlığı çekimli grupta koronal ve apikal seviyelerde azalırken, çekimsiz grupta sadece lingual tarafta kök seviyesinde önemli ölçüde azalmıştır. Alt keserlerin labial tarafındaki kemik kalınlığı hem çekimli hem de çekimsiz grupta değişmemiştir. Simfiz bölgesinin en dar yeri olan B-B' genişliği sadece çekimli grupta azalmıştır. Tartışma: Çekimli ve çekimsiz tedaviler sonrasında tüm anterior alveoler kalınlıklar azalmıştır veya değişmemiştir. Her iki grupta da özellikle palatinal tarafta benzer değişiklikler görülmüştür. Çekimsiz grupta üst keserlerin palatinal tarafındaki alveoler kemik azalırken, alt keserlerin lingual tarafındaki kemik değişmemiştir.
