  • Aesthetics means differ from cultures and times and also differ from each person's own thinking. But as a restorative dentist who works for esthetic areas, we need to have certain principles and rationale. Some functions in CAD/CAM looks very useful to match harmonious shape to adjacent teeth and also very effective and efficient when compare to the traditional laboratory technics. Also we will discuss about link abutment (Titanium-Zirconia abutment) which we need for dental implant placed anterior area where the soft tissue is thin.

  • Anterior diastemas are common esthetic problems. One of the challenges in clinical esthetic dentistry is closing anterior diastemas without creating "black triangles" between the teeth. The success of a restorative treatment in anterior teeth depends on the esthetic integration between soft tissues and hard tissues. This report describes the successfully accomplished diastema closure case by producing the emergence profile with natural contours at the gingival-tooth interface and then generating of gingival recontouring process.

  • Recently, the demand for esthetic improvement by a treatment neither time consuming nor invasive is increasing. The patient wanted the maxillary anterior teeth appearance to be improved by prosthetic treatment, not other treatments such as orthodontic, periodontal, and endodontic treatments, despite the limit of esthetic improvement. In this case, among the recent variety of all ceramic systems for the aesthetic prosthetic restoration, we selected the zirconia-based system as a method of restoration in order to conceal the discoloration of teeth. The patient was satisfied with the esthetic results.

  • In recent years, perhaps the biggest driver in new material development is the desire to improve crown and bridge esthetics compared to the traditional PFM or all-metal restorations. As such, zirconia, leucite-containing glass ceramic and lithium disilicate glass ceramic have become prominent in the dental practice. Each material type performs differently regarding strength, toughness, ease of machining and the final preparation of the material prior to placement. For example, glass ceramic are typically weaker materials which limits its use to single-unit restorations. On the other hand, zirconia has a high fracture toughness which enables multi-unit restorations. This material requires a long sintering procedure which excludes its use for fast chair side production. Developed hybrid material of CAD/CAM is contained nano ceramic elements. This new material, called a Resin Nano Ceramic is unique in durability and function. The material is not a resin or composite. It is also not a pure ceramic. The material is a mixture of both and consists of ceramic. Like a composite, the material is not brittle and is fracture resistant. Like a glass ceramic, the material has excellent polish retention for lasting esthetics. The material is easily machined chair side or in a dental lab, polishes quickly to an esthetic finish and if necessary, can be useful restoratives.

  • I think the following conditions should be met for a successful anterior aesthetic restorations. They include the patient's facial and dental harmony, the coordination between the tooth and periodontal tissue, and the continuity with the adjacent teeth. However, in the laboratory process of making restorations, the dental technician works on the model without meeting the patient in person, so he or she has to rely on his or her knowledge and skills to make restoration within limited information. In this article, I discuss the biological criteria that I think as a dental technician and the forms of restorations and how to grant them to the sound periodontal condition.

  • Digital dentistry is becoming a mainstream of dental practice. We are already used to intraoral scan, guided implant surgery, manufacture of prosthesis (CAD-CAM) in our daily practice; those are not sensational anymore. However, treatment planning with digital simulations is not spotlighted enough. In this report, a digital mockup was utilized to visualize the final goal of maxillary rehabilitation including all anterior and posterior teeth, and persuade a patient who wanted restoration of only anterior teeth. We will also discuss the use of digital mockup and its actual copy as the guide of altered vertical dimension through the clinical process.

  • Recently, esthetic dentistry has been developed because beauty is pursued by both dentists and patients. A scope of esthetic treatment has been expanded and the roles of hygienists in dental treatment have also become of importance. Generally, we make use of the ultra-sonic scaler to remove the stains attached to teeth surfaces, but when we utilize the rubber cup and pumice in prophylaxis, this increases the hypersensitivity, patient's anxiety, and chairtime. So, we substitute Air-polishing that increases patient's satisfaction and decreases chairtime for above method, Here, I would like to explain indications and contraindications, advantages and disadvantages, and usages of Air-polilshing briefly.

  • In dental esthetics, soft tissue plays an important part, probably very large portion of it. A clear understanding of the periodontal tissues and its management around teeth and implants help us to develop concepts for a modern dental treatment that addresses the needs of demanding patients in regard of esthetics and durability. When we talk about esthetic, we can say that one of the most important element is a harmonization with gingiva (soft tissue) called 'Pink Esthetic' As for the pink esthetics, gingival line(contour) takes most of the influence on esthetic result; it consists of labial gingival level, interproximal papilla height, and a line that connects them. In the gingival recession, labial gingival level and gingival contour move to the apical portion, and the root area is exposed. It leads to the unesthetic result. Root coverage technique is classically used to treat gingival recession (marginal tissue recession) of natural teeth. It is an essential technique on periodontal plastic surgery part. It is also a very useful technique to recover soft tissue problems in implant dentistry. So, root coverage technique must be mastered for a good implant esthetic result. The general overview of root coverage procedures will be discussed with step by step explanation to get more esthetic result.

  • With the increase of esthetic demands, most patients want to have restorations which are not only functional but also esthetic. For the esthetic restoration, many ceramic systems have been introduced and applied in dentistry. Among those ceramic restorations, IPS e.max system composed of lithium disilicate glass ceramic is one of the most commonly used systems because it has strength and esthetic characteristics. IPS e.max system is divided into IPS e.max Press and IPS e.max CAD according to the manufacturing methods. IPS e.max Press is fabricated through heat-pressed technique with ceramic ingot, which is very simple. The restorations which are made using IPS e.max system can apply to 3 units restoration for the anterior teeth and premolar, and single posterior tooth restoration. Cementation is one of the most important clinic procedure for the longevity of the restorations. All ceramics are bonded by resin cements, it is classified into three groups including adhesive, self-adhesive, and conventional. Variolink N, which is an adhesive resin cement and manufactured by same company with IPS e.max, is recommended for the bonding of IPS e.max restoration. Conventional and self-adhesive resin cement is also available. The aim of this review article is to provide the understanding of material properties, production procedure and clinical application of IPS e.max system.
