If complication arises after glossectomy which leads to trouble in forming food bolus or transfer of the food, it is possible that either food bolus may block the airway or dysphagia may occur as the food bolus goes down into the airway. To solve the issue, palatal augmentation prosthesis could be used. In this case, the patient with an oral cancer is having difficulties swallowing food after glossectomy. Through taking impressions of polishing surface of his denture referring his tongue movement, the complete denture for the upper jaw was created using the concept of palatal augmentation prosthesis. This new upper denture increases the palatal-tongue contact pressure, allowing the patient to perform better swallowing and better pronunciation.

A subgingival crown-root fracture presents a restorative problem to the clinician because restoration is complicated by the need to maintain the sound tooth structures. Forced eruption offers a method of treatment of teeth fractured close to the alveolar crest. Extrusion of such teeth allows elevating the fracture line above the epitherial attachment and so the proper finishing margins can be prepared. The purpose of this case is to report successful tooth restoration using forced eruption in case of crown-root fractures.

배경: 술 후 통증은 술 후 합병증의 발생가능성을 증가시키며 생체기능의 회복을 방해한다. 술 후 통증을 효과적으로 조절하기 위해선 통증의 정도를 객관적으로 평가하는 것이 필요하다. 술 후 통증은 수술의 침습도와 관련이 높을 가능성이 많다. 본 연구에서는 수술 침습도의 정도와 술 후 통증의 정도 사이의 상관관계를 확인하고자 한다. 방법: 총 153명의 환자를 수술의 침습도에 따라 4개의 그룹으로 나누었다(그룹 1: 악성종양 수술 (malignancy surgery), 그룹 2: 양악수술(bimaxillary surgery), 그룹 3: 양성 종양수술(benign cancer surgery) 그룹 4: 임플란트 & 골절 수술(implant & frature)) 수술이 끝나갈 무렵 fentanyl 700 ${\mu}g$, ketorolac 1,500 mg (총 용적 120 ml)가 포함된 자가통증조절장치를 정맥로에 연결하였다. 술 후 통증의 정도는 시각통증등급(visual analogue scale)을 이용하여 측정하였고 자가통증조절장치의 총 사용시간, 투여된 진통제의 양, bolus 투여 총 횟수를 측정하였다. 결과: 술 후 시각통증등급은 술 후 1일부터 3일까지 그룹 1, 2 군에서 유의하게 높았다. 또한 시각통증등급 3점 이상의 통증을 호소하는 환자의 비율 역시 그룹 1, 2 군에서 유의하게 높았다. 진통제 총 투여용량 및 자가로 주입한 진통제의 양 역시 그룹 1, 2군에서 3, 4 군에 비해 유의하게 높은 것을 확인하였다. 결론: 본 연구결과 외과적 수술의 침습도가 술 후 통증의 정도를 결정하는데 있어 중요한 요소임 을 확인하였다.

구강저를 통한 기관내 삽관은 1986년 Altemir에 의해 처음 소개된 바 있는데 그 후 1993년 Hoenig와 Braun 및 같은 해 Stoll 등에 의해서나, 또는 1996년 Prochno 등에 의해 계속 변형된 방법으로 문헌에서 기술되어 왔다. 이 방법은 치과 영역 특히 구강악안면외과의 외상수술시 이상적인 교합을 얻기 위해 임시 상하악간 고정(intermaxillary fixation)을 할 수 있고 중안모 골절(midface fracture)의 회복을 위한 비관 삽관의 불편함을 피할 수 있는 유리한 점이 있으며, 또한, 정복 및 고정술이 필요한 비골 골절(nasal bone fracture)에서나 두개기저골 골절(skull base fracture)에서 여러 감염 등 합병증을 피하기 위해 추천될 수 있다. 또한, 목 부위에 비심미적인 반흔을 만들게 되며 여러 합병증을 초래할 수 있는 기관절개술(tracheostomy)보다 유용할 수 있다. 본 증례보고에서는 교통사고로 두개기저부 골절을 동반한 심한 중안모 골절 환자에서 적용시킨 경우를 알아보고, 아울러 이러한 악하부 삽관의 장, 단점 및 시술 과정 등에 대해 고찰해보고자 한다.

With the evolution of the computer-aided design/computer-aided manufacturing (CAD/CAM) technology, the intraoral scanners are playing an increasingly important role, as they are the first step towards a completely digital workflow. The CAD/CAM double scanning technique has been used to transfer the information from provisional restorations to definitive restorations. In this case, a 67-year-old male with esthetically compromised anterior teeth, generalized severe attrition of teeth, and reduced vertical dimension was treated with full mouth rehabilitation including a re-establishment of the lost vertical dimension of occlusion assisted by the crown lengthening procedure. The provisional restorations were fabricated using an intraoral scanner and the CAD/CAM double scanning technique. After the period of adaption, the definitive monolithic zirconia restorations were delivered. The CAD/CAM double scanning technique successfully transferred the occlusal and morphological characteristics, obtained from the provisional restorations, to the definitive restorations.

Severely worn dentition causes various complications such as loss of tooth structure, discoloration, pulp complications and loss of function and aesthetics. In this case, the patient showed particularly severe attrition in the anterior teeth and lack of space for restoration. The amount of vertical dimension was determined based on the diagnostic wax up, and the patient's adaptation was evaluated by using a removable occlusal splint for 6 weeks. Thereafter, the coordination of the muscular nervous system, aesthetics, temporomandibular joint were re-evaluated for 3 months by restoring the fixed provisional restoration. Through the above treatment process, the final restoration was completed with full mouth fixed prosthesis using monolithic zirconia, and functionally and aesthetically stable results were obtained.

To restore a tooth with a fracture line extending below the marginal bone level, a surgical crown lengthening procedure accompanied by ostectomy could be considered to expose the fracture line and reestablish the biologic width. However, this procedure could lead to esthetic failure, especially in the anterior teeth. Therefore, orthodontic extrusion, which elevates the fracture line from within the alveolar socket without sacrificing the supporting bone and gingiva, is recommended. This technique allows for the proper placement of the crown on a sound tooth structure, with the reestablishment of the biologic width. Alternatively, surgical extrusion is an one-step procedure that is simpler and less time-consuming than orthodontic extrusion; placing and adjusting the orthodontic appliance does not require multiple visits. This study presents successful restoration in 2 cases with a crown-tooth root fracture of the maxillary central incisor treated using a multidisciplinary approach through orthodontic extrusion or surgical extrusion followed by successful restoration.

Based on rapid improvement in digital fields, many advanced digital technologies are utilized in prosthodontic treatment. Especially, intraoral scanners and 3D printing technology are commonly used, and facial scanning technology is recently being attempted to be part of these digital routines. This case report aims to introduce a digital procedure using the intraoral scanner, facial scanner, and 3D printing technology to create definitive restorations, which are esthetic and harmonious with patient's face. From thoroughly evaluated full-mouth provisional restoration which was manufactured and fitted conventionally, definitive prostheses were fabricated using various digital technique. Stable occlusion with functionally and aesthetically satisfying results were achieved.

One of the common complications of dental injury is tooth ankylosis. Unlike adults, when tooth ankylosis occurs in the adolescents, ankylosis interfered the growth of the adjacent alveolar bone, resulting in the developmental failure of the alveolar bone and subsequent open bite. The most common treatment option for ankylosed tooth is extraction. However, when prognosis of ankylosed tooth after extraction is expected to be poor due to severity of infrapositioning or prosthetic replacement cannot be performed immediately, various treatment options should be considered. This report suggests multidisciplinary treatment that might bring functionally and esthetically favorable result included alveolar bone distraction osteogenesis and decoronation of ankylosed maxillary anterior tooth with orthodontic and prosthetic treatments.

Gingival recession could occur after orthodontic or endodontic treatment. This could influence not only functional and aesthetic problem, but also patient's treatment satisfaction. There are a lot of techniques for preventing gingival recession, but laterally positioned flap with subepithelial connective tissue graft could get definite advantages such as increase of keratinized gingival width and harmonious color match between graft tissue and surrounding tissue. Clinician should select a right patient case and diagnosis with clinical and radiography exam. In a surgical procedure, getting enough amounts of subepithelial connective tissue and flap coverage should be taken into consideration. The clinical outcomes in this case report shows laterally positioned flap with subepithelial connective tissue graft could be a treatment with predictive outcome.
