Facial balance is the primary detevminant of good facial esthetics and is expressed externally by the shape of facial soft tissues. Balance of the facial skeleton is most important in prediction of orthognathic surgery, however, it is not alwags coincided to soft tissue balance because the soft tissue drapes overlying hard tissue varies in thickness and tones from case to case. So, soft tissue facial balance and esthetics also should always be considered in prediction of hard tissue changes preoperatively. The chin has a paramount importance in the overall appearance of the face and facial profile because it may express individual charactor or image. Therefore positional change of the chin must be considered in any cases as the last and important option to give an overall soft tissue balance. Two cases were referred from orthodontists only for anterior segmental of teortomuy of the chin. Pre-operative evaluation showed poor soft tissue chin profiles which were not coincided to hard tissue chin balance. We altered surgical plans to fulfill balancing soft tissue profile and then could improve overall esthetics after surgery.

Background: The dimensions and shape of the forehead determine the esthetics of the upper third of the face. Korean young people consider a broad and smooth, rounded forehead more attractive. As a result, frontal augmentation becomes more popular in patients with dentofacial deformities. Various surgical procedures and materials have been used in frontal augmentation surgery, with associated advantages and disadvantages. Silicone is a good candidate for frontal augmentation. The author presents two cases of esthetic frontal augmentation with a prefabricated silicone implant in female patients with dentofacial deformities. Case presentation: In case 1, a 24-year-old female patient underwent frontal augmentation surgery with simultaneous maxillomandibular and zygomatic osteotomies to correct facial asymmetry. A silicone implant was fabricated preoperatively using a positive template stone mold of her forehead. In case 2, a 23-year-old female patient underwent total facial contouring surgery including frontal augmentation for improved facial esthetics. A computed tomography (CT)-guided rapid prototype (RP) model was used to make the silicone implants. The operative procedure was safe and simple, and the silicone implants were reliable for a larger degree of frontal augmentation. Six months later, both patients had recovered from the surgery and were satisfied with their frontal shape and projection. Conclusions: Frontal augmentation with silicone implants can be an effective adjuvant strategy to improve facial esthetics in patients with a flat and narrow forehead who undergo orthognathic reconstruction or total facial contouring surgery.

To improve esthetics and gain beautiful smile, the maxillary anterior dentition is crucial. Through alteration of height, arrangement or color of the maxillary incisor, we can rehabilitate the esthetic smile. The perception of dental esthetics is highly subjective. Personal perceptions or judgement of dental esthetics is highly related with each individual's experience and social and cultural environment. However, there have been many efforts to establish the criteria for generally accepted esthetic norm, in order to increase the predictability of restorative treatment. For maxillary anterior restoration, not only a single tooth, but also the compositions around tooth such as facial form, lips and gum and their relationships have to be considered to create harmonious smile. It can be determined as esthetic restorations when in consonance with facial form and structures that frame the restorations. In this review article, several guidelines that are generally accepted and useful to assess the esthetics and communicate with patients and technicians will be discussed.

Periodontal disease, trauma, deformity of tooth can jeopardize the esthetics of oral and maxillo-facial region. Moreover, increasing the demand and concern about the esthetics, clinicians should place high value on esthetics during periodontal treatment. Analysis of various anatomical considerations; lip line, shape and location of marginal gingiva, and biologic width; and diagnosis should be performed prior to periodontal plastic surgery.

The aim of this clinical report is to describe the complex treatment of an adult Class III malocclusion patient who was disappointed with the outcome of a previous oral rehabilitation. Interdisciplinary treatment planning was performed with a primary indication for implant removal because of marginal bone loss and gingival recession, followed by orthodontic and surgical procedures to correct the esthetics and skeletal malocclusion. The comprehensive treatment approach included: (1) implant removal in the area of the central incisors; (2) combined orthodontic decompensation with mesial displacement and forced extrusion of the lateral incisors; (3) extraction of the lateral incisors and placement of new implants corresponding to the central incisors, which received provisional crowns; (4) orthognathic surgery for maxillary advancement to improve occlusal and facial relationships; and finally, (5) orthodontic refinement followed by definitive prosthetic rehabilitation of the maxillary central incisors and reshaping of the adjacent teeth. At the three-year follow-up, clinical and radiographic examinations showed successful replacement of the central incisors and improved skeletal and esthetic appearances. Moreover, a Class II molar relationship was obtained with an ideal overbite, overjet, and intercuspation. In conclusion, we report the successful esthetic anterior rehabilitation of a complex case in which interdisciplinary treatment planning improved facial harmony, provided gingival architecture with sufficient width and thickness, and improved smile esthetics, resulting in enhanced patient comfort and satisfaction. This clinical case report might be useful to improve facial esthetics and occlusion in patients with dentoalveolar and skeletal defects.

Facial esthetics is one of the most important goal of the orthodontic treatment and main concern of many patients. Facial esthetics should be considered in orthodontic diagnosis and treatment planning. Prediction of soft tissue profile changes after orthodontic tooth movement should be considered as well. The purpose of this study was to find out the effect of orthodontic treatment on lip profile in adult patient. The pre and post treatment cephalometric roentgenograms of 87 female adult with bimaxillary protrusion were used to analyze lip profile change. All subjects were treated with four bicuspids extraction. Obtained results were as follows . 1. Lip thickness changes after incisor retraction showed different patterns according to areas of the lip. The thickness of the red lip area showed 2.78 mm increase in average. In contrast the thickness of the cutaneous area showed 0.65 - 0.7 mm decrease according to the different cutaneous areas. 2. The length of the red lip area decreased(1.3mm) after incisor retraction. 3. The length of the cutaneous lip area increased(2.9mm) after incisor retraction.

Fibrous dysplasia(FD) is a disorder in which normal bone is replaced with pathologic tissue. When occurring in craniofacial regions, the zygomaticomaxillary complex is most commonly affected and this pathologic lesion results in facial asymmetry. and By using computer-assisted virtual simulation, precise maxillofacial contouring was achieved for harmonious facial morphology and the surgical procedure was simplified and the surgery brought satisfactory results in terms of both esthetics and functionality.
