Bite force is created by the force of adjacent teeth accompanied with tension of masticatory muscle. The bite force value is greater in male than in female and ha maximum value at first molar. Masseter muscle is associated with bite force and during muscle contraction the electric signal is expressed in EMG form. The aim of the study is to assess recovery time for masseter muscle activity and according to each part of bite force after open reduction with internal fixation when mandibular angle fracture and subcondyle fracture occurred. And to determine the appropriate period for mandibular fracture patients to have normal masticatory activity. 30 patients with normal bite condition was selected for control group and from April, 2007 to September, 2007, 20 patients who visited our department of oral and maxillofacial surgery of Dankook University, were selected for the study and were diagnosed as mandibular angle fracture and subcondyle fracture. For control group, the bite force for incisors, canine, premolars and molars and activity of the masseter muscle was measured and compared for 1, 2, 3, 4, 6 and 8 weeks. That was divided as fracture side and normal side. Mann-Whitney U test was performed for significant difference and the following result was obtained. 1. The maximum voluntary bite force for incisors, canine, premolars and molars portion were 0.113 kN, 0.182kN, 0.295kN and 0.486kN and the masseter muscle activity was 0.192 volts in the control group. 2. The maximum bite force at fracture side was recovered by 4th weeks for incisors, 6th weeks for canine and premolars and 8th weeks for molars and the masseter muscle activity was recovered by 6th weeks in the experimental group. 2. The maximum bite force at normal side was recovered by 4th weeks for incisors, 6th weeks for canine, premolars and molars and the masseter muscle activity was recovered by 3rd weeks in the experimental group. 3. The method for internal fixation by 2.0mm miniplates at both superior and inferior border had no complications according for twenty patients and had a satisfactory recovery. According to the result, patient with mandibular angle fracture and subcondyle fracture, 8 weeks was required for bite force recovery. Therefore, patients with open reduction and internal fixation under general anesthesis, it can be assumed that 8 weeks was needed after operation in order to have normal bite force and masseter muscle recovery.

BSSRO is most frequently operated among orthognathic surgery techniques for repairment of maxillofacial deformities. In case of patients with maxillofacial asymmetry accompanying mandibular protrusion who are operated by BSSRO, this study considers the recovering time for masticatory force of each tooth and Masseteric EMG and the adequate time enabling normal occlusion. The patients who are operated with BSSRO under general anesthesia in Dankook Dental Hospital, Department of OMS are selected for this study. The control group is devided into 2. 26 patients with facial asymmetry accompanying mandibular protrusion are selected for group 1 and their maximum voluntary bite force and masseteric EMG are measured. Group 2 is formed by volunteers with healthy dentition who are measured maximum bite force and masseteric EMG on both sides of the mouth. At the week of 3rd, 5th, 7th, 9th and 11th, Mann-Whitney U test is carried on for statistical analysis and the result is as follows. 1. Patients with mandibular protrusion showed apparently low maximum bite force and masseteric EMG than patients with normal occlusion. 2. In comparison with control group 1, Occlusal force is regained in incisors and canines at the 9th week and in premolars and molars, 11th week and masseteric EMG is regained at 11th week. 3. Comparing to normal occlusal patients, no recovery could be found in experimental group in every parts of the mouth.

산모의 다중예측 인자를 이용한 임신 합병증 예후에 관한 다변량분석 목적: Maternal serum markers(AFP, uE3, hCG ), Unexplained down syndrome screen positive에 의한 태아예후를 비교하기위함. 연구방법: 1994년 3월부터 1996년 2월까지 임신 2기에 삼성제일병원을 방문하여 Triple marker test를 시행하고 본원에서 분만 기록이 있는 단태아 5,284례를 대 상으로 하였다. 각 산모 혈청 표지물질들은 radioimmunoassay kit를 이용하여 측정하였고 다운 증후군 스크린 양성은 α-software(Ver. 4.0)를 이용하여 산출하였다. 임신과 관련된 임신 합병증 예후의 기준은 조기태반 박리는 분만시 태반 소견을 기준으로 하였으며, 저체중아는 2500gm 미만, 만삭전 파수는 임신 37주 이전에 조기 양막 파수되는 경우로 하였다. 결과: 검사를 받은 산모의 평균 연령은 30±4.8세이며, 임신횟수는 평균 2.27, 출산횟수는 0.46이며, 검사를 시행한 평균 임신주수는 17.1주이었다. 저체중아는 357례(6.8%), 미숙아는 253례(4.8%), 전치태반은 108례(2.0%), 만삭전 파수는 68례(1.3%), 임신중독증은 66례(1.3%), 조기태반박리 24례(0.5%),자궁내 태아사망은 20례(0.4%)이었다. 이러한 임신 합병증 예후와 산모의 연령 AFP,hCG,uE3,그리고 Unexplained Down syndrome screen positive의 통계적 연관성에 관한 분석에서 35세 이상군은 조기태반 박리, 미숙아, 전치태반에서, AFP 2.0 이상군은 자궁내 태아사망, 저체중아, 임신중독증, 미성숙 조기 양수 파막, 미숙아에서, hCG 3.0 이상군은 자궁내 태아사망, 저체중아, 임신중독증, 미숙아, 전치태반에서, uE3 0.75 미만군에서는 자궁내 태아사망, 저체중아, 미숙아에서만, 그리고 unexplained Down syndrome screen positive에서는 조기태반 박리 , 자궁내 태아사망, 저체중아, 미숙아에서 통계적인 의미가 있었다. 또한 임신 합병증 예후와 관련된 혼란 변수를 조절하고 가장 영향력 있는 인자를 알기위해 multivariate logistic regression을 시행하였다. 자궁내 태아사망은 AFP 2.0 MoM이상, 저체중아는 AFP 2.0 MoM이상, hCG 3.0MoM이상, uE3 0.75 MoM 미만, 임신 중독증은 AFP 2.0 MoM이상, 미성숙 조기 양수 파막은 AFP 2.0 MoM이상, 미숙아는 AFP 2.0 MoM이상, 전치 태반은 35세 이상의 산모군과 hCG 3.0 MoM 이상군에서 P value 0.05 미만으로 통계적으로 의미있는 결과가 나왔으며, 조기태반 박리의 경우 35세 이상의 산모군에서만 P value 0.07이었다. 결론: 임신 합병증 예후를 예측하기위한 예측인자로서 산모의 고령 나이를 비롯해 산모혈청의 AFP, hCG, uE3과 Unexplained Down syndrome screen positive는 모두 다변량 분석에서 통계학적으로 의미가 있으며, 또한 다변량 분석에서는 증가된 AFP이 임신 합병증을 예측하는데 가장 신뢰성 있는 인자임을 알 수 있었다. Purpose : To evaluate a role as over 35 years, maternal serum markers, and a false positive screen for Down syndrome were the predictor of adverse pregnancy outcome. Materials and Methods : From Mar.1994, through Feb.1996, 5284 women were screened triple test to detect Down syndrome in the second trimester and were delivered Samsung Cheil hospital. The values of each maternal serum markers were measured with radioimmunoassay. And then, the screen positive of Down syndrome was calculated using α-software Version 4.0. The adverse outcome of the fetus and the mother included low birth weight(LBW) ( <2500gm), prematurity( <37 gestational weeks), placenta previa, preterm premature rupture of membranes(PPROM), pregnancy induced hypertension(PIH),abruptio placenta, and intrauterine fetal death(IUFD). The predictor markers included over 35years, elevated α-fetoprotein (AFP), elevated human chorionic gonadotropin(hCG), lowered unconjugated estriol (uE3), and a false positive screen for Down syndrome. Results : Mean age and mean gestational weeks in the study were 30±4.8 years and 17.1 weeks respectively. The adverse pregnancy outcomes were 357 LBW(6.8%), 253 prematurity(4.8%), 108 placenta previa(2.0%), 68 PPROM(1.3%), 66 PIH(1.3%), 24 abruptio placenta(0.5%), and 20 IUFD(0.4%). In univariate analysis, over 35 years was significantly associated with abruptio placenta, prematurity, and placenta previa, elevated MS-AFP( >2.0 MoM) associated with IUFD, LBW, PIH, prematurity, and PPROM , elevated MS-hCG (>3.0 MoM) associated with IUFD, LBW, PIH, prematurity, and placenta previa, lowered uE3 (<0.75) associated with IUFD, abruptio placenta, LBW, and prematurity.(P <0.05). In multivariate logistic regression analysis, IUFD was significantly associated with only elevated MS-AFP, LBW associated with elevated MS-AFP, elevated MS-hCG, and lowered uE3, PIH associated with only elevated MS-AFP, PPROM only elevated MS-AFP, prematurity only elevated MS-AFP, and placenta previa over 35 years, elevated MS-hCG.(P <0.05). However, abruptio placenta was not significantly associated with predictor markers.(P >0.05) Conclusions : Some predictors such as over 35 year, elevated hCG, lowered uE3, a false positive screen for Down syndrome were significantly associated with adverse pregnancy outcome. Also in multivariate analysis, we identified especially elevated AFP to be the most reliable predictor for adverse pregnancy outcome.
