심미란 단어가 우리에게 친숙한지 20여년이 흐른 지금도 새로운 것에 도전하듯이 어려움을 가져다주는 것은 아마도 진화라기보다는 기본적인 로드맵이 안 되어 있어서 아직도 서툴고 회피하는 것은 아닌지 싶다. 보철마다 특성상 장점과 단점이 있는 것이기에 그 적응증을 숙지하고 그에 맞는 진단과 적절한 선처치가 될 때 기대할만한 결과를 얻을 것이다. 이 과정에 환자에 대한 정보공유와 치과의사와 치과기공사간의 소통과 전문화된 각자의 역할은 매우 중요한 치료과정이며 이 통로를 얼마큼 잘 제도화 시켰느냐가 심미기공물의 성패가 달려 있다고 보아도 과언 이 아닐 것이다. 위의 서술한 치료과정의 바탕으로 가장 장점이 많고 보존적의미가 있는 라미네이트 심미보철에 관해 살펴보고자 한다.

Background: The present study aimed to analyze which curriculum is the most relevant to dental hygiene students when they participate in clinical practice in order to provide a useful reference for preparing educational guidance in this field. Method: The survey utilized in the present study consisted of six questions about general characteristics, such as grade, satisfaction with major, amount of clinical practice, period of clinical practice, place of clinical practice, and the most interesting are during clinical practice. When evaluating curriculum relevancy, the following were ranked on a 5-point Likert scale, where 5 = very useful, 4 = comparatively useful, 3 = normal, 2 = comparatively unuseful, 1 = very unuseful: difference in requirements in the field of clinical practice, reason for this difference, and question about the utility of each curriculum. On this scale, higher points implied higher relevance. Result: The highest groups of curricula regarding curriculum utility were as follows: operative dentistry (59.6%), pre-clinical practice (55.2%), dental materials and clinical practice (54.4%), and prosthetic dentistry (49.6%). The lowest groups of curricula regarding curriculum utility were as follows: oral physiology (2.0%), oral histology and embryology (1.6%), and oral microbiology (1.2%). These results imply a lack of connection between the curriculum and tasks in clinical practice. Conclusion: Based on the results of the present study, it appears that both theory and practice courses of the clinical curriculum must be conducted systematically, and that there is a need to conduct education for the fundamental curricula, such as oral physiology, oral histology and embryology, and oral microbiology, regarding the relevance of tasks practiced in clinics.

Background: The authors studied the hemodynamic effect influent by using the novel high concentration of lidocaine HCl for surgical removal impacted lower third molar. The objective of this study was to evaluate the hemodynamic change when using different concentrations of lidocaine in impacted lower third molar surgery. Methods: Split mouth single blind study comprising 31 healthy patients with a mean age of 23 years (range 19-33 years). Subjects had symmetrically impacted lower third molars as observed on panoramic radiograph. Each participant required 2 surgical interventions by the same surgeon with a 3-week washout period washout period. The participants were alternately assigned one of two types of local anesthetic (left or right) for the first surgery, then the other type of anesthetic for the second surgery. One solution was 4% lidocaine with 1:100,000 epinephrine and the other was 2% lidocaine with 1:100,000 epinephrine. A standard IANB with 1.8 ml volume was used. Any requirement for additional anesthetic and patient pain intra-operation was recorded. Post-operatively, patient was instructed to fill in the patient report form for any adverse effect and local anesthetic preference in terms of intra-operative pain. This form was collected at the seven day follow up appointment. Results: In the 4% lidocaine group, the heart rate increased during the first minute post-injection (P < 0.05). However, there was no significant change in arterial blood pressure during the operation. In the 2% lidocaine group, there was a significant increase in arterial blood pressure and heart rate in the first minute following injection for every procedure. When the hemodynamic changes in each group were compared, the 4% lidocaine group had significantly lower arterial blood pressure compared to the 2% lidocaine group following injection. Post-operatively, no adverse effects were observed by the operator and patient in either local anesthetic group. Patients reported less pain intra-operation in the 4% lidocaine group compared with the 2% lidocaine group (P < .05). Conclusions: Our results suggest that a 4% concentration of lidocaine HCl with 1:100,000 epinephrine has better clinical efficacy than 2% lidocaine HCl with 1:100,000 epinephrine when used for surgical extraction of lower third molars. Neither drug had any clinical adverse effects.

본 연구는 골격성 III급 개방교합자의 악교정 수술 전, 후 설골과 상기도의 변화를 3D-CT를 이용하여 관찰하고 이를 정상교합자와 비교하기 위하여 시행하였다. 전치부 개방교합을 동반한 골격성 III급 부정교합으로 진단되어 악교정 수술을 받은 환자 중 12명을 선정 후, 3D-CT를 통해 설골과 상기도의 3차원 입체영상을 분석하여, 악교정 수술 전, 후의 설골의 위치 변화 및 상기도의 부피 변화를 살펴보고, 이의 결과를 정상교합자 10명과 비교하였다. 설골은 골격성 III급 개방교합군에서 악교정 수술 전에 정상교합군의 설골에 비해 전방에 위치하고 있었고 악교정 수술 후 설골은 후, 상방으로 변화하였으나 유의성은 관찰되지 않았다. Hyoid plane과 mandibular plane이 이루는 각은 악교정 수술전의 골격성 III급 개방교합군이 정상교합군보다 큰 값을 나타내었고, 악교정 수술 후에는 그 차이가 더욱 증가하였다. 골격성 III급 개방교합군의 상기도 부피는 정상교합자보다 작으며 이는, 악교정수술 후에 더욱 감소하였다. 3차원 영상 분석 결과, 골격성 III급 개방교합자의 상기도는 정상교합자에 비해 좁으며, 하악골 후퇴술 이후 더욱 감소하기 때문에 이는 수술적 개선의 안정성에 영향을 줄 수 있음을 알 수 있었다.

Background: The dimensions and shape of the forehead determine the esthetics of the upper third of the face. Korean young people consider a broad and smooth, rounded forehead more attractive. As a result, frontal augmentation becomes more popular in patients with dentofacial deformities. Various surgical procedures and materials have been used in frontal augmentation surgery, with associated advantages and disadvantages. Silicone is a good candidate for frontal augmentation. The author presents two cases of esthetic frontal augmentation with a prefabricated silicone implant in female patients with dentofacial deformities. Case presentation: In case 1, a 24-year-old female patient underwent frontal augmentation surgery with simultaneous maxillomandibular and zygomatic osteotomies to correct facial asymmetry. A silicone implant was fabricated preoperatively using a positive template stone mold of her forehead. In case 2, a 23-year-old female patient underwent total facial contouring surgery including frontal augmentation for improved facial esthetics. A computed tomography (CT)-guided rapid prototype (RP) model was used to make the silicone implants. The operative procedure was safe and simple, and the silicone implants were reliable for a larger degree of frontal augmentation. Six months later, both patients had recovered from the surgery and were satisfied with their frontal shape and projection. Conclusions: Frontal augmentation with silicone implants can be an effective adjuvant strategy to improve facial esthetics in patients with a flat and narrow forehead who undergo orthognathic reconstruction or total facial contouring surgery.

The traditional orthognathic surgery treatment consists of three steps: preoperative orthodontic treatment, orthognathic surgery, and postoperative orthodontic treatment, and the average treatment period is usually two years. Also, patients with Class III malocclusion should spend more time getting their facial features worse during the decompensation process. However, most of the patients who want orthognathic surgery visit the chief complaints of appearance improvement, and resolve this address as soon as possible. The concept of $^{\circ}{\AE}$Surgery - First 'does not cause a facial imbalance caused by decompensation for the pre - operative correction period, and the patient can obtain an improved facial profile immediately after the operation. In addition, the correction period is shortened by Regional Acceleratory Phenomenon (RAP) after surgery. However, it is not applicable to all patients. Patients with severe crowding, severe curve of spee or reverse curve of spee, severe transverse discrepancy of the maxilla and mandibular arch, and severe incisal angles are less likely to apply the technique. Although it is not yet possible to apply this technique to all patients, it has many advantages over the conventional method. Especially, the patients' preference is increasing due to the rapid appearance improvement and the shortening of the total treatment period.
