Hubungan Variasi Morfologi Sella Tursika Dengan Maloklusi Klas III Skeletal Di RSGMP FKG USU

ABSTRAK

LatarBelakang:Sella tursika merupakan struktur anatomi yang umum digunakan
dalam bidang ortodonti untuk pengukuran sefalometri, evaluasi morfologi
kraniofasial, relasi hubungan rahang dengan kraniumdan superimposisi serial
sefalometri.Tujuanpenelitianiniadalahuntukmengetahuihubungan

khususnya di RSGMP FKG USU Medan.Bahandan Cara: Penelitian ini dilakukan
pada 104 sampel dimana terdiri dari dua kelompok sampel yang masing-masing
berjumlah 52 sampeldengan rentangusia17-35 tahun. Kelompok pertama yaitu foto
rontgen sefalometri lateral dengan maloklusi Klas I skeletal dan kelompok kedua
yaitu foto rontgen sefalometri lateral dengan maloklusi Klas III skeletal.Untuk

ABSTRACT

Background: The sella turcica is one of the commonly used orthodontic landmarks
in determining and diagnosing various problems of the facial skeleton. The purpose
of this study was to determine relationship between the morphology of sella turcica
and Class III malocclusion in Indonesia specially in RSGMP FKG USU Medan.
Materials and Methods: The sample in this study 104 lateral lateral cephalograms

with range age 17-35 years old and were divided into two groups. First group
consisted of 52lateral cephalograms with Class I malocclusion and the second
groupconsisted of 52 lateral cephalograms with Class III malocclusion.The
morphology of sella turcica was analysed based on theory Axelsson et al.Result:
Sellaturcica with normal morpholoy with greater found in Class I malocclusion (67,3
% of the subjects) and inClass III maloclusion only 17,3 % of the subjects with
normalmorphology.Bridging of the sellaturcica with greater found in Class III
malocclusion (30,8 % of the subjects) and inClass Imaloclusion only found 13,5
%.Conclusion: There was a significant difference between morphology of sella
turcica in Class III malocclusion and morphology of sella turcica in Class I
malocclusion. There was relationship between morphology of sella turcica and Class
III malocclusion
Key words: morphology of sella turcica, bridging of sella turcica, Class III
malocclusion.
