Restoration of missing oral tissues by using implant therapy is one of viable options in prosthodontic treatment. The purpose of oral rehabilitation are function, esthetics and phonetics. Recently, with the increasing esthetic demand of the patient, dentists and laboratory technicians are more concern ed about natural appearance of implant prostheses. There are so many factors which affect final esthetic results of treatment such a shape, color, proportion, gingival contour etc. To provide natural and vivid looking artificial prostheses to a patient, the careful diagnosis, treatment plan and laboratory Support is crucial. Several cases will be reviewed and discussed in terms of material, gingival shape, contour, speech and connection mode etc. to fabricate natural looking implant prostheses.

With the explosive increase of esthetic demands by patients, many dental materials for the esthetic restoration have been introduced. Recently, zirconia based restorations are using for the cases of single crown, bridges, implant prostheses etc. Zirconia have superior mechanical properties and biocompatibility. Owing to the properties of high strength, zirconia has to be manufactured by CAD/CAM system. Dental CAD/CAM system is a futuristic treatment and technical system which makes it possible to produce the precision and uniform prosthesis and also standardize the treatments. This article introduces the characteristics of zirconia, fabrication procedure using CAD/CAM system and procedure for the cementation of zirconia based restoration.

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.

Purpose: Pink gingival esthetic especially on the anterior teeth has been an important success criterion in implant-supported restoration. Inter-implant papillae are a critical factor for implant esthetics, and various techniques for inter-implant papilla reconstruction have been introduced. The aim of this study is to suggest and evaluate a surgical technique for reconstructing inter-implant papillae. Methods: A 28-year-old man had an implant placed on the #13 and #14 area. Four months after implant placement, a second stage surgery was planned for inter-implant papilla reconstruction. At the time of the abutment connection, I-type incisions were performed on the #13i & #14i area followed by full-thickness flap elevation and connection of a healing abutment on underlying fixtures without suture. Results: Two weeks after the second stage implant surgery, soft tissue augmentation between the two implants was achieved. Conclusions: I-shaped incisions for papilla reconstruction performed during the second stage implant surgery were useful for inter-implant papilla reconstruction and showed a good esthetic result.

To be successful in aesthetic prosthetic treatment, the crown part aesthetic (White Esthetic) and the tissue part aesthetic (Pink Esthetic) must be well controlled. Clinically, white esthetics are the area of dental technicians and pink esthetics are the area of dentists, but a deeper understanding of counterparts can produce more successful results. In this paper, I will briefly describe this process.

No one really doubts that the hottest area of dentistry in 21st century would most likely be 'implant'. With the support of a vast amount of research, implant has been successfully and rapidly absorbed into the field of general dentistry including private practitioners. For teeth with hopeless(or refractory) periodontitis or periapical pathosis, with no hesitation most dentists would think extraction as the sole treatment option followed by prosthodontic replacement possibly including implant. Not many dentists would take Trasplantation/Replantation as another treatment option for a particular condition. Dentistry is often more focused on 'Restoration' than 'Preservation' of natural dentition. 'Biologic Implant' is obviously much closer to the concept of 'Preservation'. Many different types of biologic implant system have been introduced to clinical dentistry so far. Many of those have failed to earn reasonable acknowledgement despite of the clinical success they brought. For some reason biologic implant has rather been alienated for long time. RPI(Ring Pin Implant) is designed to improve the prognosis and success rate of transplanted/replanted teeth. RPI is a Ti-based custom made implant system. It is fabricated either by electric casting or milling process. The major feature RPI gas is the 'ring & hole' structure. The hole should be no less than 1mm diameter to allow bone bridge formation thru it. The ring structure and bone bridge formation creates anti-torque activity, which largely increases the 'initial stability' of the transplanted/replanted teeth. It is also reported that RPI is beneficial in the aspect of resisting root resorption following replantation/transplantation procedure.

It is challenging to produce esthetic implant restoration in the narrow anterior maxilla region where insufficient volume of alveolar bone could limit the angle and position of implant fixture, if preceding bone augmentation is not considered. Ideal angle and position of implant fixture placement should be established to reproduce harmonious emergence profile with marginal gingiva of implant prosthesis, bone augmentation considered to be preceded before implant placement occasionally. In this case, preceding bone augmentation has been operated before esthetic implant prosthesis in narrow anterior maxilla region. Preceded excessive bone augmentation in buccal area allowed proper angulation of implantation, which compensates unfavorable implant position. Provisional restorations were corrected during sufficient period to make harmonious level of marginal gingiva and interdental papilla. The definite restoration was fabricated using zirconia core based glass ceramic. Functionally and esthetically satisfactory results were obtained.

In the case of an extraction in the maxillary anterior region, immediate placement of implant-supported fixed prosthesis can be considered as a treatment option. Fewer surgical operations, reduced treatment time, and optimal availability of existing bone are obvious advantages of the method; however, when applied in the continuous maxillary anterior region, inter-implant distance must be carefully considered, as well as accurate diagnosis and treatment planning for predictable outcome. In this case report, immediate placement of two implants in the continuous maxillary anterior along with bone graft following the extraction of root rests, and the restoration of provisional and implant-supported fixed prosthesis on a 63-year-old patient had resulted in both esthetically and functionally satisfactory clinical outcomes.

When planning oral rehabilitation for maxillary edentulous patients, fixed prosthetic restoration using implants, complete denture restoration or overdentures using implants can be considered as treatment methods. In the case of complete denture restoration, it does not require additional surgery and is relatively economical. In the case of implant-supported fixed prostheses, the functional part is generally superior to that of complete denture restoration, but there are cases in which implant placement is clinically difficult. Recently in consideration of the patient's needs and the condition of the remaining alveolar bone, after partial implant placement, a method of restoring with a removable partial denture using implant-supported surveyed crown is also being attempted. This case is a case of performing a removable partial denture restoration using implant-supported surveyed crown in the anterior maxilla, and showing satisfactory esthetic and functional results.
