Abstract

Objective: Miniscrews are widely used in orthodontic treatment for the purpose of anchorage control. Maximum anchorage can be acquired by the use of miniscrews. Maxillary miniscrew has many clinical advantage for orthodontic treatment. Maxillary sinus, tooth root can be an obstacle for maxillary miniscrew installation. The purpose of this study was to find the safest area and direction of miniscrew insertion in consideration of the maxillary sinus. Methods: The maxillary sinus area of 40 patients (20 male, 20 female) was measured using 3D computed tomography and 3D reconstruction program. Results: The maxillary sinus floor was located most inferiorly between the 1st molar and 2nd molar and located most superiorly between the 1st premolar and 2nd premolar. Buccal bone thickness from the maxillary sinus is significantly thicker between the 1st molar and 2nd molar and significantly thinner between the 1st premolar and 2nd premolar. The area between the 1st premolar and 2nd premolar has a significantly longer vertical distance from CEJ to sinus in consideration of buccal bone thickness. Conclusions: Considering maxillary bone thickness, the posterior area has advantages over the anterior area for installing miniscrews safely and preventing perforation.

본 연구는 전산화 단층촬영 영상으로 상악동의 형태를 파악하여 교정용 미니스크류를 안전하게 식립할 수 있는 위치를 찾고자 시행되었다. 남자 20명, 여자 20명의 3차원 전산화 단층촬영 사진을 촬영한 후 3차원 영상프로그램을 이용하여 상악동의 형태를 계측하여 통계 분석하였으며 다음과 같은 결과를 얻었다. 상악동저에서 백악법랑경계까지의 골두께는 제1대구치와 제2대구치 사이에서 유의하게 얇았고, 제1소구치와 제2소구치 사이에서 유의하게 두꺼웠다. 상악동저에서 협측 상악골 외연까지의 두께는 제1대구치와 제2대구치에서 유의하게 두꺼웠으며, 제1소구치와 제2소구치 사이에서 유의하게 얇았다. 이상의 결과를 바탕으로 안전하게 미니스크류를 식립하여 교정치료의 영역을 넓힐 수 있을 것이다.
