In spite of the word esthetics having been familiar to us during the last twenty odd years, difficulties are still faced nowadays as if new challenges constantly emerge. This is perhaps best interpreted as a tendency to avoid dealing with it owing to the fact we are not quite used to it. It is probably a lack of a basic roadmap for esthetics, not of evolution. Every prosthesis has its own strengths and weaknesses. Expected results would be obtained if and when the patient's adaptation to prosthesis is correctly anticipated, appropriate diagnoses made and optimal pre-operative measures taken. At this stage, communication and patient information sharing between the dentist and dental technician are very important factors in the treatment process, as well as each party's unique specialized role. It would not be an exaggeration to state that the success of a lab made prosthesis would depend on how well these factors have been systemized. Based upon the above treatment procedures, it is now intended to examine esthetic prostheses involving porcelain laminate veneers that enable the most conservative treatment with the most significant favorable characteristics.

생활양식의 변화에 따라 유치 및 유영구치에 대한 traumatic injury가 크게 증가하고 있으며 이는 어린이나 보호자에게 심리적으로 커다란 영향을 미칠 수 있는 것이다. 어린이의 신체중 구강주위에 가장 많은 injury를 받는 것으로 나타나고 있고 하악전치 보다는 상악전치가, 여자 보다는 남자가 더욱 많은 injury를 받는 것으로 알려져 있으며 유전치에 대한 injury가 가장 많은 시기는 걷는 것, 달리는 것을 처음 재우게 되는 1½~2½세 사이이다. 물론 같은 어린이가 수회의 injury를 받을 수 있으며 특히 조심성이 없거나 가정이 파괴된 상태의 어린이에 있어 사고 위험이 높은 것으로 나타나고 있다. 일단 injury가 발생하면 가능한 한 빨리 치료가 이루어져야 하는데 유치는 계승치 맹출에 의하여 정상적인 치근 흡수현상을 나타내고 발육중인 유영구치는 치근이 미완성된 상태이므로 성숙된 영구치와는 처치방법이 다르며 때 고려해야 할 사항으로, ① management of child, ② degree of root resorption (degree of permanent tooth development), ③ space problems, ④ degree of parental concern, ⑤habits, ⑥ speech, ⑦ esthetics등이 있다.

In patient of long standing malunited maxillary fracture, maxillary osteotomy or refracture seems to be justifiable. This is a case of the patient, a 60 year old Korean female patient, presented a long-standing malunited maxillary fracture with dish-type face and functional disturbance in mouth opening. We performed upon her Le Fort I osteotomy only via labial-buccal horizontal incisions in one-stag operation. The result was good in esthetics and function.

Reconstruction of the maxilla is quite a difficult challenge for reconstructive surgeons. The maxilla is the most important part of the midface, which contributes to facial esthetics, mastication, swallowing, speech, supporting orbital contents and sinus function. Free fibular flap is most versatile to reconstruct jaw bone because of its adequate length, containing both soft and bony tissues and acceptance of dental implants. In this case report, a reconstruction of the maxilla using free fibular flap and dental implants is described in which rapid prototype was used before surgery to simulate the final prosthetic results.

Dental clinicians commonly encounter extrusion of the anterior teeth due to localized alveolar bone loss in adult patients with chronic periodontitis. This pathologic migration of the anterior not only may cause loss of functional anterior guidance and continuous periodontal destruction, but also can lead to esthetic disaster. In fact, most frequently reported chief complaint of the patients with extruded anterior teeth is the 'loss of esthetics', not the periodontal problem itself. The utilization of the expertise and skills in the various dental disciplines is thought to be the best treatment modality for the ultimate functional and esthetic attainment. Interdisciplinary therapy, involving periodontics, orthodontics, and restorative dentistry, was performed for the highest levels of patient and provider satisfaction in this case.

The purpose of this study is to report a clinical case of a patient whose vertical dimension of occlusion was lost. There are many reasons for the loss of vertical dimension and one of those can be a tooth wear problem. Thus in this article we will review shortly types of tooth wear: attrition, abrasion, and erosior. And layour the basic philosophy and principles in regaining the esthetics and function of a patient's oral condition with a history of psychological wear, through full mouth restorations.

The availability of high-technology systems that use computer-aided design(CAD) and computer-aided machining(CAM) is on the increase. One such system is the Procera system, which fabricates an all-ceramic crown composed of a densely sintered, high-purity aluminum oxide coping combined with a compatible veneering porcelain. Strength, precision of fit, esthetics, cementation, and biocompatibility are among the many factors that concern clinicians when fabricating all-ceramic restorations with this system. This paper reviews the long history and background development of technical, laboratory and clinical applications and presents, in summary form, the data from the many studies on the Procera system.

We were usually make use of Viggo activator for orthodontic the state prognathous. But, it inconvenient for use because demend of long time until orthodontic use finished for restoration of everybody production and function(esthetic, mastication, phonetic). So, we were enough effect obtained for everybody function with this improve. 1. Improves Viggo activator inconvenience of insertion and remove. 2. It can be set with considering of functional and esthetics. 3. Get a orthodontics effect without lonf period. 4. Have no convenience to mastication at setting with occlusal correction at anytime.

Amelogenesis imperfecta patients suffered common clinical problems of poor esthetics, teeth sensitivity, and loss of occlusal vertical dimension. Amelogenesis imperfecta is a group of inherited disorders primarily affecting dental enamel. Variants of amelogenesis imperfecta generally classified hypoplastic, hypocalcified, or hypomaturation types based on the primary enamel defects. The mildest problems were found in the pitted hypoplastic type whereas the most severe problems were encountered in the hypocalcified type amelogenesis imperfecta. Management stragies include composite resin veneer and jacket crowns for anterior teeth as well as steel crowns for posterior teeth. Knowledge of the clinical features and dental complications of each variants if amelogenesis impecta helps in the diagnosis of the condition and allows institution of early preventive measures. The objective of this paper is to provide a review of the current concepts of the wide spectrum of etiological factors involved in the pathogenesis of this significance clinical entity in the primary dentition.

Dr. Walter Wright first presented the results of his studies on acrylic resins in July, 1937. The use of resins for adaptation in inlay and crown and bridge prosthesis was first reported in June 1940 by Harris. There has been now and acceptable list of several physical and mechanical properties of acrylic resins which have been studied to a considerable extent by various researchers, or determined from clinical experience. They include; pleasant esthetics, taste, odor, cleanliness, compatibility with oral tissue, dimensional stability, water sorption by imbibition, hardness, ease and success of repair, weight, thermal coefficient of expansion and strength to resist functional stress. The author carried a series of experiments forward to check the strength. Specimens which were cured at boiling temperature showed weaker strength than those ones which were cured at 72℃.
