A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : The aim of this study was to compare the treatment efficiencies and root resorption amounts of two different incisor intrusion mechanics. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Thirty-two patients with deep bite and elongated maxillary incisors were randomly allocated two treatment groups: Connecticut intrusion arch group (CG) or Mini-implant group (MG). In both groups approximately 60 g of force applied between central and lateral incisors. Dentoalveolar effects were studied via cephalograms taken before and after 5 months of intrusion while root resorption was assessed using periapical roentgens. Paired t-test was used to evaluate differences within groups. The changes observed in both groups were compared by using independent t-test. R Re es su ul lt ts s: : While the overbite reduced significantly in both groups (p<0.001), this amount was greater in MG (p<0.01). The center of resistance (CR) of incisors showed significant apical movement (p<0.001) in both groups with greater values observed in MG (P<0.05). The labial tipping and sagittal advancement of the incisor edge was significant in the treatment groups (p<0.001); these changes were greater in MG. Apex of the central incisor displayed significant backwards movement (p<0.05) with no intergroup difference (p>0.05). Incisors in both groups showed significant root resorption (P<0.000) which was significantly greater in MG compared to CG (P<0.05). C Co on nc cl lu us si io on n: : Mini-implants were more efficient in bite-opening. However they also led to more root resorption and labial tipping compared with the Connecticut intrusion arch.K Ke ey y W Wo or rd ds s: : Tooth movement; Connecticut; orthodontic anchorage procedures Ö ÖZ ZE ET T A Am ma aç ç: : Bu çalışmanın amacı farklı iki keser intruzyon mekaniğinin tedavi etkinliği ve kök rezorpsiyonu miktarı yönünden karşılaştırılmasıdır. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Derin kapanış ve uzamış maksiller kesicilere sahip 32 hasta rastgele iki tedavi grubuna ayrıldı: Connecticut intrüzyon arkı grubu (CG) veya mini-implant grubu (MG). Her iki grupta santral ve lateral kesiciler arasından yaklaşık 60 g kuvvet uygulandı. Dentoalveolar etkiler keser intruzyonundan önce ve 5 ay sonra alınan sefalometriler ile değerlendirilirken kök rezorpsiyonu periapikal filmlerle değerlendirildi. Eşle-ştirilmiş t-testi ile grup içindeki farklar analiz edildi. Her iki gruptaki değişimler bağımsız ttesti ile karşılaştırıldı. B Bu ul lg gu ul la ar r: : Her iki grupta overbite anlamlı miktarda düşerken (p<0.001), bu miktar mini-implant grubunda daha fazla idi (p<0.01). Keserlerin direnç merkezi (CR) miniimplant grubunda daha fazla değerde olmakla birlikte her iki grupta da önemli düzeyde apikale yer değiştirdi (p<0.001). Labial devrilme ve kesici kenarının sagittal ilerlemesi tedavi gruplarında önemli bulunurken (p<0.001), bu değişiklikler miniimplant grubunda daha fazla idi. Santral kesicilerin apeksleri gruplar arası fark olmaksızın...
Although the severity of GOSLON scores might predetermine the extent of which the airways are affected from the cleft, a larger sample size is needed in future studies.
