  • This is to investigate the difference between craniofacial correlation of Angle's class III malocclusion and that of normal occlusion. For this investigation, 28 adult males and famales, who have class III malocclusion, and 35 adult males and 46 adult famals., who have normal occlusion were selected to measure actual dimension of cranial base and to investigate ratio of various parts of maxillofacial skeleton against cranial base. Class III malocclusion were, also , classified based on SNA and SNB angle in normal range. Results were as follows. 1. In class III malocclusion, actual dimension of cranial base were appeared to be less than normal occlusion in both sex. 2. In class III malocclusion, values were less than normal occlusion in BN/ptm-A in both sex, but had no significance between two. 3. In class III malocclusion, ramal inclination, mandible inclination, BN/Go-Pog, lower genial angle were appeared to be greater. Thus, characteristic mandibular protrusive appearance of class III malocclusion was due to relative ratio and morphologic characteristic of mandibular body dimension against cranial base. 4. In class III malocclusion, upper incisors were labially tilted and lower incisors were lingually tilted compared to normal occlusion. 5. In typing of class III malocclusion, the most common type was found to be one which maxillas were in normal range, while mandibles were in protrusive tendency.

  • The preclinical and clinical studies reviewed herein show that rhBMP-2 induces normal physiologic bone in relevant defects in the craniofacial skeleton. The newly formed bone assumes characteristics of the adjacent resident bone, and allows placement and osseointegration of dental implants. Clearly, the bone inducing capacity of rhBMP-2 is carrier and site dependent. rhBMP-2 in an absorbable collagen sponge carrier induces relevant bone formation in space providing defects. Space providing carries extends this possibility to non-space providing sites. Notably, some ceramic and polymeric biomaterials may substantially interfere with rhBMP-2 induced osteogenesis.

  • Facial skeletal remodeling was revolutionized more than 30 years ago, by the work of Tessier and other craniofacial surgeons. However, the need to correct the skeleton in the upper third of the face is not frequently diagnosed or treated in aesthetic facial surgery. Here, we report on the aesthetic correction of a protrusive forehead. A patient visited our hospital for aesthetic contouring with a prominent forehead. The anterior wall of the frontal sinus was removed with a craniotome via the bicoronal approach. After the excised bone was repositioned, it was fixed with a titanium mesh plate and screws. An electric burr was used to contour the supraorbital rim and frontal bone. Once the desired shape was achieved, the periosteum was replaced, and the wound was closed in layers. When performed properly, frontal sinus contouring could significantly improve the appearance in patients with a prominent forehead. Plastic surgeons must carefully evaluate patients with a prominent forehead for skeletal remodeling that involves the accurate and safe repositioning of the anterior wall of the frontal sinus.

  • The author measured the right and left craniofacial skeleton using posteroanterior cephalography of 124 male and 97 female subjects of ages ranging 2-6 years, 7-13 years and adult group on Korean. Statstical parameters were calculated by computer from the data. The results of the study were as follows. 1. In the male and female group of deciduous dentition, the right side measurements were slightly greater than the left side measurements, and generally male measurements were greater than female measurements. 2. In the both sex group of mixed dentition, the right side measurements were greater than the left side measurements, and in comparision of sex, the female recognized more growth, and development than male, especially on the cranial base, lateral maxilla, lower maxilla and dental region. 3. In the permanent dentition group, regardless of sex, the right side measurements were greater than the left side measurements, and in the sex difference, male was conspicuously greater than female on both sides measurements. 4. In the permanent dentition group, the asymmetry of the face was striking than deciduous dentition and mixed dentition group.

  • 조선대학교 치과대학 학생 중 안모형태와 교합상태가 양호하고, 교정치료의 경험이 없는 정상교합자 74명 (남자 38명, 여자 36명)을 대조군으로 하였고 조선대학교 부속 치과병원 교정과에 내원하여 악교정 수술을 통한 교정치료가 필요하다가 진단된 골격성 III급 부정교합자 성인 45명 (남자 23명, 여자 22명)을 실험군으로 하여 두부규격방사선 사진을 촬영하고 Burstone & Legan방법에 의해 각각의 계측항목별로 남여를 비교 분석하여 악교정 수술이 필요한 골격성 III급 부정교합환자의 악안면 골격 특성에 대해 다음과 같은 결론을 얻었다. 1. 골격성 III급 부정교합 환자는 함몰된 안모를 지니고 있었고 (P<0.001), 여자에서 뚜렷한 상악골 열성장 (P<0.nt)과 하악골 과성장 (P<0.01)을 보인 반면, 남자에서는 통계학적인 유의성이 존재하지 않았고 상,하악골 연조직의 전,후방적인 비교에서는 특징적으로 남자는 하악골 연조직의 과다한 전방돌출 (P<0.001), 여자는 상악골 연조직의 과다한 후퇴 (P<0.001)을 보였는데 이는 골격성 III급 부정교합이 남자는 하악골 과성장, 여자는 상악골 열성장에 의해 주로 기인됨을 알 수 있다. 2. 골격성 III급 부정 교합을 지닌 남여 모두에서 특징적으로 MP-HP 각과 genial angle이 커서 하악골의 전하방 과성장을 보인 반면, ramus height는 남여 모두에서 아무런 영향도 미치지 않았으며, 상악중절치는 순측경사, 하악전치는 설측경사 되어 있었는데 이는 악교정 수술을 위한 술전교정 치료시 이러한 치성보상을 정상으로 회복시켜 각 골격구조내에서 치아들이 적절하게 위치되도록 하는 것이 중요하다고 것을 의미한다. 3. 여자에서 상안면고경에 비해 하안면고경이 특징적으로 짧았고, 남자의 lower facial throat angle이 특징적으로 작았다. 이는 골격성 III급 부정교합이 남자에서는 하악골의 과다한 하방 성장및 긴 목, 여자에서는 하악골의 전방으로의 과다성장및 짧은 목에 기인하는 것으로 보인다.

  • The surgical treatment of craniofacial disorders, using metallic internal osteofixation system has inspired an evolution with advanced operative technique and fixation devices over past two decades. As any other surgical procedures, this procedure also associates problems such as infection, palpability, loosening, and restrict craniofacial skeleton growth, which lead to undue secondary operations for removal. These problems are improved by using bioabsorbable osteofixation system. We compared the patient's subjective symptoms using bioaborbable system versus metallic osteofixation system in zygomatic bone fracture. we should take the individual steps (postoperative 2 weeks, and 1 year) in treating fractured zygoma. From August, 2001 to August, 2003, we used bioabsorbable osteofixation system in 28 patients in zygomatic fracture ($Biosorb^{TM}FX^{(R)}$) and compared 23 patients who were treated with metallic osteofixation system. There was no significant difference in the both groups in subjective symptoms and postoperative result.

  • This study intended to calculate the cephalometric norms of Korean adult and to compare those with norms of the North American Caucasian by Moyers. Cephalometric headplates of 41 males and 31 females ranged in age from eighteen to twenty-six with normal occlusion and pleasing face were employed for this investigation. The tracings of the standard lateral cephalograms were analyzed by Moyers' method. As a result of this study, the following conclusion can be made. 1. Norms of Korean adult male and female were calculated. 2. There was no significant sexual difference in the basic craniofacial morphology. 3. The size of craniofacial skeleton was larger in male than in female. 4. The Korean male showed lower value of mandibular plane angle to craial base than that of the Caucasian male. 5. There was no significant difference in the anterior total facial height, however, in the posterior facial height the Korean male was larger than the Caucasian male, which manifested that the Korean male held more square-shaped profile. 6. The anteroposterior length of anterior and posterior cranial base, maxillary and mandibular skeletal and dentoalveolar effective length of the Korean male were shorter than those of the Caucasian male, and this suggested that the craniofacial profile depth of the Korean male was shorter than that of the Caucasian male.
