研究室紹介
Professor Sung-Bum Kye's research lab specializes in oral and maxillofacial implantology, with a strong focus on clinical and biological aspects of dental implant integration, particularly in challenging anatomical sites such as the posterior maxilla. The lab investigates bone regeneration techniques, including sinus augmentation using xenografts like Bio-Oss®, and evaluates biomaterials—such as bone cements, mineral trioxide aggregate (MTA), and flowable resin-based materials—for their efficacy in root canal retreatment and apical sealing. Additionally, the lab explores infection control in dental settings, examining the impact of preoperative mouthrinses on aerosol-borne pathogens during ultrasonic scaling procedures.

15Purpose: The aims of this study were to measure the distance of the intraosseous vascularanastomosis in the anterolateral wall of the maxillary sinus from different reference points,and to correlate the location of the intraosseous vascular anastomosis with the tooth positionand the residual bone height of the maxilla. Methods: Computed tomography (CT) images were taken from 283 patients undergoingdental implants placement in the posterior maxilla. Three horizontal lines were drawn atthe ridge c
Purpose: Implant beds with an insufficient amount of cortical bone or a loss of corticalbone can result in the initial instability of a dental implant. Thus, the objective of this studywas to evaluate the effect of bone cement grafting on implant initial stability in areas withinsufficient cortical bone. Methods: Two different circumferential defect depths (2.5 mm and 5 mm) and a control(no defect) were prepared in six bovine rib bones. Fourteen implants of the same type andsize (4 mm×10 mm) wer
Purpose: The aim of this report is to investigate the efficacy of anorganic bovine bone xenograft(Bio-Oss®) at maxillary sinus floor augmentation. Materials and methods: Two male patients who missed maxillary posterior teeth were included. They were performed maxillary sinus floor augmentation using anorganic bovine bone xenograft(Bio-Oss®). After 10 or 13 months, the regenerated tissues were harvested using trephine drills with 2 or 4mm diameter and non-decalcified specimens were made. The spe
Purpose: The aerosol generated by ultrasonic scaler can contain bacteria or virus which can penetrate into body through respiratory systems of dentists, dental hygienist or patients. The aim of this study is to evaluate the effect of chlorhexidine digluconate as preoperative mouthrinse or lavage for ultrasonic scaler on the reduction of viable organisms in aerosol produced during periodontal treatment using ultrasonic scaler. Methods: 30 patients with moderate chronic periodontitis were included
본 연구의 목적은 Super-EBA, MTA, Dyract-flow를 근관 역충전재로 사용하였을 때의 근단부 폐쇄 능력을 전기화학적 방법을 통해 알아보고자 하는 것이다. 48개의 단근치를 Profile을 사용하여 근관형성한 후, Gutter-percha cone으로 수직가압 충전을 시행하였다. 근단부에서 3mm 되는 부위를 bur로 절단한 후, ultrasonic device로 3mm 깊이의 역충전 와동을 형성하였다. 각 실험군은 Super-EBA, MTA, 혹은 Dyract-flow로 역충전하고 4주에 걸쳐 전기화학적인 방법으로 치근단 누출의 변화를 측정한 후, Repeated measures of ANOVA로 통계분석하였다. 그 결과 모든 시편에서 시간에 따른 치근단 누출의 증가가 관찰되었으나, 각 실험군 간에 누출의 차이는 나타나지 않았다. 이러한 결과는 Dyract-flow의 치근단 역충전재로써의 사용 가능성을 시사한다.
The effect of PDGF-BB loaded TCP/ chitosanmicrogranules on new bone formation
Purpose: The aim of this study was to compare the number of live and dead bacteria attached to, or within, the stratified squamous epithelium lining the tissue side of the gingival sulcus. Materials and Methods: A total of 50 patients was examined and classified into healthy or diseased sites according to inflammatory status of the gingival tissue. The surface of stratified squamous epithelium was removed by gentle scraping of the gingival sulcus with curettes. The cells were processed in the l
Purpose: Many researches showed loss of alveolar bone in fresh extraction socket and even in case of immediate implant placement. The aim of this study was to evaluate the effect of non-resorbable barrier membrane on the change of buccal and lingual alveolar bone in immediate implant placement into periapically infected extraction sockets. Materials and methods: Immediate implants were placed into artificially induced periapical lesion of mandibular premolars after complete debridement using buc
Purpose: The purpose of this study was to evaluate the soft tissue and bone change around two adjacent implants in onestage implant surgery. Methods: Eleven subjects (7 males, 4 females) who were needed placement of 2 adjacent implants in the molar area were included. The two implants were placed with the platform at the level of the alveolar crest. The interproximal bone between the 2 implants was not covered with gingiva. After surgery, an alginate impression was taken to record the gingival s

본 연구의 목적은 인산칼슘제제인 MBCPⓇ, PolyboneⓇ을 발치와에 이식 후 치유 양상을 조직학적으로 관찰하는 것이다. 비글견의 소구치를 발치 후 발치와에 골이식재를 이식하였으며, 3개월간의 치유기간을 거친 후 조직표본을 제작하여 현미경으로 치유 양상을 관찰하였다. MBCPⓇ, PolyboneⓇ은 조직학적으로 비슷한 치유 양상을 보였으며 이물반응이나 염증 반응 없이 신생골 생성을 유도하여 정상적인 치유를 도모하였다. 치유된 조직의 조직 계측학적 평가에서 신생골 비율은 골이식재를 이식하지 않은 대조군이 34.5%, MBCPⓇ는 28.4%, PolyboneⓇ은 23.8%였으며, 골이식재를 포함한 전체 mineralized tissue의 비율은 각각 34.5%, 42.9%, 37.3% 였다. 이상의 결과에서 MBCPⓇ, PolyboneⓇ은 발치와에 사용할 골이식재로 가치가 있는 것으로 생각된다.
A 3 year-retrospective study of survival rate in single Brnemark TiUniteTM implant
구강 내 단일 치아를 상실한 경우 기존에는 고정성 보철물을 이용하여 수복하는 방법이 일반적이었지만, 최근에 와서는 임플란트를 이용하여 수복하는 것이 보편화되고 있다. 본 연구는 단일 치아 결손 시 TiUnite™ 표면 처리한 임플란트를 이용하여 수복한 경우를 후향적으로 조사하여 그 생존율을 분석한 것이다. 2002년 9월부터 2006년 12월까지 삼성서울병원에서 단일 치아 결손 부위에 식립된 총 269개의 TiUnite™ 표면 처리한 임플란트 중 21개는 인접한 임플란트가 있거나, 기록이 누락되거나 관찰 기간이 짧아 연구에서 제외되었다. 248개의 임플란트 중 상악에는 129개(52.0%) 하악에는 119개(48.0%) 식립되었다. 수술 부위에 치조골 재생술을 시행한 경우는 총 100개(40.3%)였으며, 상악동 거상술이 시행된 증례는 총 36개(14.5%)였다. 수술 당일부터 관찰 기간은 평균 26.0±11.8 개월이었으며, 그 기간 동안 실패한 것으로 간주된 임플란트는 12개로
