  • When making crown and bridges on anterior regions, many practitioners consider the esthetics the most. For this reason functional aspect are not considered as much as the esthetics. If the occlusion on the anterior region are not formed correctly, movement of the temporomandibular joint can be disturbed and excessive stress can be occur that pathologic condition can be under lied. On this case presentation will show the importance of the anterior guidance and suggest the appropriate protocol of using customized anterior guide table. A 45years old male had to remake both of the upper central and lateral PFM because of the porcelain fracture. The new PFM crowns were made conventional methods without considering the anterior guidance. After the temporary setting, the patient complained of discomfort and short looking upper anteriors. To solve these problems we had to restore the palatal contour and length of the new crowns by making customized anterior guide table using temporary crowns that contains patient's old anterior guidance. This procedure which is copying the pt's comfortable anterior guidance to the final prosthesis made them to be esthetic and patients to feel comfortable.

  • Introduction : The purpose is a retrospective evaluation of the clinical results of the radial forearm flap transfer for foot reconstruction. Materials and methods : We evaluated 21 cases with medical records including etiology, wound dimension, presence of infection, associated fracture, ischemic time of free flap, complication of donor and recipient site. The final results were evaluated with our clinical score (walking, shoe-in, cosmetic). Results : Defects were located on the heel (12 cases), dorsum of foot (4 cases) and sole (5 cases). Mean wound dimension was $7.56{\times}6.0cm$, and mean ischemic time of free flap was 94.5minute. There were superficial skin necrosis (1 case), recurrent ulceration (2 cases) in recipient site, and no complication in donor site but complaint about cosmetic problem (3 cases). The clinical score showed excellent in 14 cases, good in 4 cases, fair in 1 case and poor in 2 cases. Conclusion : We consider the radial forearm flap could provid the stable and durable restoration of normal foot contour without debulking in the foot reconstruction and achieved normal ambulation and cosmetic satisfaction.

  • Since the implant became the important treatment modality in dentistry, the research and clinical effort to mimic natural tooth appearance have been pursued. While the rehabilitation of mastication and occlusal appearance was focused in the past, more esthetic and functional restoration was preferred recently. To fulfill this demand, the clinicians should consider the axial contour, papilla space, subgingival appearance, as well as the shape of occlusal surface. In the surgery part, there have been significant advances in the adequate formation of bone and soft tissue through the careful reflection on the surgery time and incision. When the dentist has good knowledge about this aspect and passion for the final product, he or she can acquire better results.

  • Skull or facial bone defect causes cosmetic and functional problems. On going efforts were taken to reconstruct the craniofacial bone defect with autogenous bone or alloplastic materials. Between 2001 and 2003, we reconstructed 15 cases with small to large craniofacial bone defect using Hydroxyapatite paste($BoneSource^{(R)}$, Leibinger Corp., Dallas, TX, U.S.A) and calvarial bone graft. All patients were followed up by clinical examination and periodic radiographic studies for an average of 1.6 years (range, 6 months to 2 years and 6 months). One complication case was noted with $BoneSource^{(R)}$ exposure. Otherwise, there was no evidence of adverse healing, wound infection, foreign body reaction and seroma collection in other patients. Adequate 3-dimensional aesthetic restoration of calvarial contour was noted in each case. In conclusion, $Bonesource^{(R)}$ is relatively safe and rigid material for craniofacial bone defect and reasonable method for the reconstruction of craniofacial bone defects.

  • The goals of lip reconstruction are to provide oral competence, adequate support for the lower lip, contour restoration, adequate lip sulcus, and adequate oral aperture. The composite radial forearm palmaris longus free flap is thin enough that it can be folded onto itself without a significant increase in bulk. The flap is easy to dissect, the pedicle contains long vessels of large diameter, and the skin is a good color and texture match for the perioral region. Moreover, the vascularized tendon can be used for lower lip reconstruction. This makes the flap ideally suited for total lower lip reconstruction. We experienced the case of total lower lip excision and reconstruction with the radial forearm free flap including palmaris longus tendon, so we reported that case with literature. The patient has a lower lip squamous carcinoma(T3NIM0), and performed a total lower lip excision with right modified radical neck dissection and left extended supraomohyoid neck dissection, and a reconstruction with radial forearm free flap includng palmaris longus tendon. The oral competence and masticatory function were nearly normalized and cosmetical result was very acceptable.

  • It will be a real good news for the people who were lost their hometown by the construction of a large dam to be restored to the former state. Focused on Cheung-Pyung around where most part were flooded by the Chungju large Dam founded in early 1980s, we used Remote Sensing Technique in this study in order to restore topographical features before the flood with 3 dimensional effects. We gathered comparatively good satellite photos and remotely sensed digital images, then we made a new color image from these and the topographical map which had been made before the flood. This task was putting together two kinds of different timed images. And then, we generated DEM including the outskirts of that area as harmonizing current contour lines with the map. That could be a perfect 3D image of Cheung-Pyung around before when it had been flood by making perspective images from all directions, north, south, east and west, for showing there in three dimensions. Also, flying simulation we made for close visiting can bring us to experience their real space at that time.

  • Objectives: The use of fat grafts in maxillofacial sculpturing is currently a common technique. Unlike fillers, autologous fats unite with facial tissues, but long-term results may still be unsatisfactory. Sharing long-term follow-ups can be helpful in making outcomes more predictable. Materials and Methods: The data from patients who were admitted from 2014 to 2016 for fat augmentation were collected. In all cases, fat grafts were injected by blunt cannula using a tunneling technique in different planes. A fan shape order for the malar, periorbital, nasolabial fold, mandibular angle and body, and perioral area was established. Results: Autologous fat was used for different sites of the maxillofacial regions. Of 15 patients, two patients were not satisfied due to fat graft resorption. For this, further injections were performed six months after the first injection using preserved fat grafts. One patient continued to be dissatisfied. There were no other complications related to fat transplants. Conclusion: Fat transplantation is a safe, reliable, and non-invasive method for facial contour and facial soft tissue defect restoration. Additional methods such as mesenchymal stem cells along with fat injection increase the survival rate of transferred fat.

  • The treatment of areas demanding esthetic requirements, such as maxillary anterior teeth, should take into account the achievement of a healthy, harmonious to the surrounding tissue, and an attractive smile line. In this case report, smile line, soft tissue and hard tissue morphology, and the anatomy and proportion of the tooth, must be considered. In patients with unesthetic maxillary anterior ratio due to inadequate gingival contour and diastema caused by peg lateralis, it would be challenging to achieve an esthetic restoration by orthodontic treatment alone. In such case, after orthodontic treatment, dento-gingivo-facial compositional diagnosis and analysis, followed by gingivectomy and prosthodontic restoration is needed to improve the interdental mesial/distal, width/length ratio to achieve a satisfactory esthetic result. In addition, when improving the tooth proportion of peg lateralis by prosthodontic treatment, Porcelain laminate veneer (PLV), which results in less tooth structure loss, reproduction of similar shade to that of the proximal tooth and high transparency, is recommended. This case report demonstrates esthetic improvements by prosthodontic restoration through systematic diagnosis and treatment procedure in patients with unesthetic maxillary anterior proportion after orthodontic treatment due to peg lateralis by means of two female patients aged twenty years old.

  • With the introduction of dental implants, restoration of missing teeth with conventional fixed or removable partial dentures is being replaced with implants. Especially, with young patients, not only longevity but also esthetic factors need to be considered. Implant restorations provide long-term success functionally but, esthetic complications such as, marginal exposure due to gingival recession, loss of the papilla and dark color of metal abutments may occur. Recently, zirconia restorations with CAD/CAM technology provide functional, biocompatible and esthetic restorations possible. All-ceramic restorations using the pressed ceramic technique show better fracture toughness values than those of the conventional porcelain veneering technique. Pressed ceramic technique creates the veneer design in wax and the lost wax technique is used to create the restoration. The final contour of the restoration may be controlled during wax-up. A 22-year old female patient was restored with dental implants and zirconia restorations using the pressed ceramic technique presenting short-term but optimistic prognosis.

  • Developing of digital technique, it is possible to fabricate implant prostheses for edentulous area using intraoral 3-dimentional information throughout implant diagnosis and treatment process. It is being changed that from the method using CAD/CAM, producing prostheses by model scanning after conventional impression and model processing, to the method of fabricating implant provisional restorations and customized abutments by digital impression after connecting digital impression copings (scanbody) and implant fixtures without models. But, this digital method has not been actively used for implant prostheses not yet. Specially, it is short of intraoral digital impression cases for immediate provisional restorations of the maxillary anterior implants. The gingival contour impression of maxillary anterior area is very important for esthetic restorations. Accordingly, in this case report, the using a digital impression coping (scanbody) and digital impression by CEREC Omnicam (Sirona, Bensheim, Germany) or Trios (3shape, Copenhagen, Denmark) were introduced for immediate provisional restorations in 3 cases needed a single implant restoration in maxillary anterior area. The clinical results were satisfactory on the convenience and accuracy of digital impression technique and the good esthetics of final restorations.
