Purpose: Due to the presence of various muscles around lips, variety of facial expression can be made and changes from aging process such as wrinkles can develop on the facial skin by the action of multiple muscles. In animals, skin and muscles are developed in the entire body. On contrast, they are well developed only in the face and just one is present in the neck and the palm. Alar band was defined as outer wrinkle formed by zygomaticus minor muscle, which is common in Koreans. This study aimed to investigate clinical prevalence of alar band. Materials & Methods: Subjects were chosen from 780 new patients who visited private clinic in Gyeonggi province for orthodontic treatment. Presence of alar band was examined from the smile extraoral photos. Correlation among skeletal form, lip protrusion, gender, and age were evaluated. Results: Prevalence of alar band was higher in women (27.9%) than in men (18.5%) with statistical significance (p<0.05). With respect to age, prevalence of alar band was 19.4% in age 0-9 y, 16.9% in age 10-19 y, 31.2% in age 20-29 y, 39.5% in age 30-39, 56.5% in age 40-49. Prevalence was gradually increased from patients in their 20s to patients in their 40s and statistical significance was found (p<0.001). Concerning SN_NP, prevalence was 26.2% in normodivergent facial type, 22.0% in hyperdivergent facial type, and 32.2% in hypodivergent facial type. Hypodivergent facial group had higher prevalence but statistical significance was not observed. Statistically significant difference was not found regarding upper lip. However, prevalence of the alar band was 26% in patients with normal lower lip, 14.7% in patients with pretruded lower lip, and 33.3% in retruded lower lip. The prevalence was higher in patients with retruded lower lip with statistical significance (p<0.05). Conclusions: 27.8% on previous anatomical study and this study showed 27.8% prevalence of alar band in clinical smile photographs. Clinical photograph study showed that alar band was more prominent in women, older people, and people with retruded lips with statistical significance. This will provide valuable diagnostic information for esthetic consideration.

With the development of treatment of hard and soft tissue around the implants, the implant restoration is increasingly used in the maxillary anterior region which is very important aesthetically. However, the aesthetic reconstruction of the maxillary anterior region is still challenged. Three following conditions should be fully satisfied for aesthetic prosthesis restoration; reconstruction of hard tissue, soft tissue and harmonic prosthesis. In this case report, hard and soft tissue augmentations were performed at atrophied maxillary incisor. Additionally, customized impression coping and provisional restoration were used to make the final restoration.
Digital Dentistry; Yesterday, Today, and the Future

Since its introduction to the dentistry, the CAD/CAM technology has been used over fifteen years. The application of CAD/CAM started from coping fabrication, expanded to the posterior full crown, and anterior restoration manufacture has also become widespread recently. While the development of machine was rapid, the advance of zirconia block was the fastest. Although some differences exist among individuals, the various natural tooth color can be expressed through the zirconia coloring itself without porcelain build up. And the texture characteristics can be reproduced just by CAD design. In this article, the development history of digital dentistry was summarized.
Consideration on the esthetic problems from implant cases

The critical factors affecting the esthetics of anterior implants can be summarized as following: 1) Correct positioning of implant fixture, 2) Enough amount of alveolar bone, 3) Optimum volume of soft tissue. The position of implant is probably the most important factor in obtaining esthetic treatment outcome. The 3-dimensional orientation of implant is determined by the position on the alveolar ridge and its direction. Clinicians often try to mimic natural teeth when fabricating restorations. During the course of esthetic diagnosis and treatment, however, one should not forget to consider the correlation between facial pattern, lips, gingiva, alveolar ridge, as well as remaining dentition. Since anterior region is biologically unfavorable when compared with posterior region, one minor discrepancy in positioning of implant can cause esthetically undesirable treatment outcome. If one understands the biological and prosthetic meaning of implant' s 3-dimensional position, he or she can achieve superior esthetic outcome in anterior region.
What would we meet for the implant dentistry: A Case Report

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.
Esthetic complete denture fabrication utilizing Biofunctional Prosthetic System (BPS)

The growing of healthy aged edentulous peoples in these days increases the demands of denture which is excellent in function and aesthetic. The Biofunctional Prosthetic System(BPS) is being introduced as a curriculum in a large number of schools in the United States, Europe and Japan. Each stages of BPS are standardized and systematized, on this account BPS is the system that even less experienced clinicians is able to produce highly satisfactory denture for patients. Additionally, the combination of BPS and suction mechanism of mandibular complete denture would make it possible to produce stabilized mandibular denture during oral function. The purpose of this article is to describe a process of producing fuctionally and aesthetically outstanding denture by using BPS combined with mandibular suction mechanism.
