The purposes of this study were:1) to determine the normal range of CR-CO discrepancy in normal occlusion group ; 2) to evaluate the changes of condylar position and craniofacial morphology between centric relation and centric occlusion before and after stabilization splint therapy in malocclusion group outside the normal range of CR-CO discrepancy. The normal occlusion group consisted of 80 subjects who had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not been treated orthodontically and had no signs or symptoms of temporomandibular joint dysfunction. 71 malocclusion patients enrolled for orthodontic treatment at the Department of Orthodontics, College of Dentistry, Chosun University comprised the malocclusion group, little variation of growth factor by the second molar eruption. They had CR-CO discrepancy beyond normal range and were subdivided into anterior-posteriorly -[25 Class I (0$\geq$4), and 24 Class III (ANB$\leq$0)] : vertically - [20 Normodivergentscy (30$\geq$34), and 18 Hypodivergency (SNGoMe$\leq$30)] ; and sexually - [26 Male and 45 Female]. For malocclusion group, stabilization splint with mutually protected type of occlusal scheme was applied for three months. Panadent articulators, Panadent condylar position indicator (CPI), and lateral headfilm were used to investigate the influence of stabilization splint on condylar position and craniofacial morphology. The results of this study were as follows. 1. The amounts of CR-CO discrepancy in normal occlusion were that the antero-Posterior component (${\bigtriangledown}X$) was $0.56\pm0.46mm$ (Male:$0.63\pm0.42mm$, Female:$0.49\pm0.50mm$) ; the supero-inferior component (${\bigtriangledown}Y$) was $-0.75\pm0.48mm$ (Male:$-0.76\pm0.52mm$, Female:-$0.73\pm0.43mm$) : and the transverse component (${\bigtriangledown}Z$) was $-0.33\pm0.28mm$ (Male : $-0.38\pm0.29mm$, Female:$-0.31\pm0.27mm$). 2. The condylar position was in normal range after stabilization splint therapy. 3. The mandible was always rotated infero-posteriorly after stabilization splint therapy. 4. Antero-posteriorly, Class III malocclusion responded very well to the stabilization splint therapy. 5. Vertically, Hyperdivergency responded very well to the stabilization splint therapy 6. Sexually, Male responded very well to the stabilization splint therapy.

본 연구는 조선대학교 부속 치과병원 교정과에 내원하여 교정치료를 시행하고 있는 환자중 Panadent 교합기 및 condylar position indicator(CPI)를 이용하여 중심위-중심교합 편위양을 측정한 결과, 전후방 및 수직적 편위양이 1.00mm이내, 측방편위양이 0.30mm 이내인 정상범주를 넘는 부정교합 환자 47명을 대상으로 하여 3개월간 교합안정장치를 24시간 장착하고, CPI 및 transcranial projection을 이용하여 교합안정장치 장착전과 장착후의 하악과두의 위치변화를 관찰한 결과 다음과 같은 결론을 얻었다. 1. CPI상의 모든 군에서 중심교합-중심위 사이에 통계적인 유의성이 있었다(p<0.001). 2. transcranial projection상의 superior joint space의 Rt와 Lt+Rt/2에서 중심교합-중심위 사이에 통계적인 유의성이 있었다(p<0.05). 3. CPI상의 모든 superior-inferior components군에서 교합안정장치 사용 전, 후의 중심교합-중심위 사이에 통계적인 유의성이 있었다(p<0.01). 4. transcranial projection상의 superior joint space의 Rt를 제외한 모든 군에서 교합안정장치 사용 전, 후의 중심교합-중심위 사이에 통계적인 유의성이 없었다. 이상의 결론을 종합해 볼 때 중심교합-중심위 사이의 변화를 평가하는데는 transcranial projection보다 CPI가 보다 유용하며, 교합안정장치는 하악과두의 전, 후방적 위치변화보다는 수직적 위치변화에 미치는 영향이 보다 큰 것으로 보인다.

Purpose: The zygomatic arch is a key element which composes the facial contour. In many cases of zygomatic arch fracture, it is difficult to fix rigidly the fractured segments. If reduced bone segments were not fixed rigidly, they are proven to be displaced by mastication or unintentional external forces. So, unfixed zygomatic arch fracture after reduction may require a external device of prevention of collapse. We introduce a new protector which stabilizing the fractured segments to prevent for collapse of the reduced zygomatic arch fracture. Methods: After reduction of zygomatic arch with blind approach(Gillies', Dingman or Keen's approach), bone segments was pulled with percutaneous traction suture in medial aspect of zygomatic arch. Then, the suture was fixed with Aqua $splint^{(R)}$, externally. And intraoperative and postoperative X-ray was done. The splint was removed on 14 days after the operation. Results: 5 patients were treated with this method. 4 patients of total patients had no collapse in zygomatic arch. There was minimal collapse in one patient. Postoperative complications such as facial nerve injury, mouth opening difficulty, contour deformity, infection, scar were not observed. Conclusion: In comparison with other techniques, this technique has several advantages which are simple and easy method, short operation time, no scar, less soft tissue injury, and facilitated removal of splint. Therefore, Aqua $splint^{(R)}$ would be a good alternative to prevent for collapse in unstable zygomatic arch fractures

In this paper, we designed 3D-printed orthopedic splint models for patient-specific external coaptation on fracture healing and analyzed the stability of the models through finite element method (FEM) analysis under compressive load conditions. Polylactic acid (PLA) and acrylonitrile-butadiene-styrene (ABS) based 3D splint models of the thicknesses 1, 3, 5 and 7 mm were designed, and Peak von Mises stress (PVMS) and maximum displacement (MD) of the models were analyzed by FEM under compressive loads of 50, 100, 150, and 200 N. The FEM results indicated that PVMS and MD values, regardless of material, had a negative correlation with the thickness of the models and a positive correlation with the compressive load. There was a risk of splint deformation under conditions more extreme than 100 N with 5 mm thickness. For successful clinical application of 3D-printed orthopedic splints in veterinary medicine, it is recommended that the splint should be produced not less than 5 mm thickness. Also, it is expected to be stable when the splint is applied to situations with a compressive load of 100 N or less. There is an advantage of overcoming the limitations of the existing bandage method through 3D-printing technology as well as verifying the stability through 3D modeling before application. Such 3D printing technology will be widely used in veterinary medicine and various fields as well as orthopedics.

Purpose: To measure the differences of the splint pin angulation and the position of the planned implant site after conventional tomographic analysis. Materials and Methods: The angulation and the location of the metal splint pin retained in acrylic stent were compared with the corrected angulation and the location of the implant fixture on the 331 tomographic images. Results: The stent pins were located buccal in 40%, lingual in 10% to the corrected implant site after analysis of the conventional tomographic image. The angle and the location of the maxillary splint pin were mainly directed buccal on incisor and canine regions. The angle and the location of the splint pins in premolar and molar regions needed less corrections in both maxilla and mandible. Conclusions: This study demonstrated that the use of tomographs was essential for successful dental implant planning.
