과학 기술의 발전으로 인류의 각종 질병을 이해하고그에 따른 새로운 수술방법, 의료기기 및 의약품과 같은 신의료기술의 개발이 증가하고 있다. 우리는 최근의 치의학 분야 신의료기술의 등록 및 허가와 인식 현황을 알아보기 위해 2012년부터 2016년 7월까지의신의료기술 등록과 허가 현황을 연도, 기술구분, 진행현황, 주요 시술 의료인으로 분류하여 분석하였으며, 그 중 치과의사 활용기술에 대한 사항을 추가적으로분석하였다. 또한 의료계 종사자의 신의료기술 인식현황을 알아보기 위해 2016년 7월에 서울대학교치과병원 치과의료기기 중개임상시험센터에서 개최한‘신의료기술 신청에 관한 워크숍’에 참가한 25명이 회신한 설문지와 대한구강악안면외과학회 회원 중 11명의설문지를 취합하여 결과를 도출하였다. 설문조사에 참여한 응답자들은 신의료기술의 신청절차에 관해서는 잘 모른다는 응답이 많았으며, 신의료기술 등록 및 허가 현황에 대해서는, 전체 1092건의 등록 건수 중 치과의사 활용기술은 19건이었으며, 그 중 신의료기술로 채택된 항목은 단 2건이었다. 치의학의 발전을 위해서는 신의료기술에 대한 정부의적극적인 홍보와 치의학계의 관심이 필요하다 판단되었다.
The purpose of this case report is to present a case of free gingival graft for treatment of mandibular incisor labial gingival recession relapsed after laterally positioned flap surgery. A 22 year-old female patient with discomfort and labial gingival recession on left mandibular central incisor was treated. The patient had been treated root coverage on same site by laterally positioned flap surgery, but treated site had relapsed in one month. Exposed root surface was covered by free gingiva from left palatal area. Although gingival color did not completely match with adjacent gingiva, more than 5mm keratinized gingiva was attained. The patient showed no further recurring pain and recession on gingiva after 5 months from the surgery. In conclusion, the root coverage with gain of keratinized gingiva could be achieved through free gingival graft from palate on relapsed gingival recession.
In the case of failed fixed implant prosthesis accompanied by abutment screw fracture, fractured screw fragment must be removed to use the existing implant fixtures. A 61-year-old male patient, who had a failed maxillary fixed implant prosthesis accompanied by three abutment screw fracture, hoped to reconstruct the maxillary implant prosthesis, while maintaining the existing implant fixtures. To use the existing implant fixtures, fractured screw fragments were removed. A maxillary implant overdenture using available existing implants was planned. Bar-attachment with Locator was used for implant splinting, denture stability, and retention. Final impression was taken after treatment of peri-implantitis. Jaw relation registration was taken to evaluate available interarch space for bar-attachment. After fabricating bar-attachment, centric relation was taken. Implant overdenture using bar-attachment with Locator was delivered after wax-denture evaluation. This case report showed that a satisfactory clinical result was achieved by implant overdenture using existing implant fixtures in a maxillary edentulous patient.
A wide variety of benign and malignant lesions and other diseases can develop on oral mucosa. Oral mucosal lesions can also be associated with an underlying systemic disease, so their correct diagnosis, which may even share similar clinical and demographic features, is always a challenge for a dentist. Common oral mucosal lesions include candidiasis, herpes viral infection, leukoplakia, recurrent aphthous stomatitis, pemphigus, lichen planus and benign migratory glossitis. The differential diagnosis of these lesions are based on a thorough review of the patient’s past medical and dental history and a complete oral examination. The knowledge of clinical features such as size, location, morphology, color, and pain is helpful in establishing a diagnosis. In addition, diagnostic tests, including microbiologic and laboratory tests and biopsies are usually required for establishing a proper diagnosis.
The aim of this study is to examine the incidence of odontogenic tumors and to review the clinical and radiological findings for the most frequent three types in Korea. Odontoma, ameloblastoma and keratocystic odontogenic tumors are the most frequent odontogenic tumors in Korea. We provide an overview of these tumors based on clinical and radiographic findings.
Oral and maxillofacial cyst is defined as an pathogenic cavity with an lining epithelium and connective tissue wall. Cysts of the jaws and periapical regions vary in histogenesis, treatment and prognosis. Cysts with similar clinical and radiographic can be shown different histopathologic features. Cysts are classified into odontogenic cysts and nonodontogenic cysts. Cysts are also divied into true cysts and pseudocyst. True cysts are lined with an epithelium, however pseudocysts are not lined with epithelium. A periapical cyst, dentigerous cyst and odontogenic keratocyst is clinically common and important lesions at dental clinic.
