Proper management of provisional prosthesis is key to success in prosthodontics. Provisional restoration on maxillary anterior missing area frequently come across a incident of falling off especially in patients with long span pontics and oval arch shape. This is because maxillary anterior teeth are more exposed to horizontal force than the posterior teeth and additional anterior cantilever effect will negatively affect to the retention of provisional prosthesis. Beside that maxillary anterior provisional prosthesis should provide proper incisal guidance during the mandibular functional movements. However occlusal contacts on the prosthesis in maximum intercuspal position are located on opposite side of fulcrum line of prosthesis which will cause removing force against the provisional prosthesis. This case report present that provisional implant prevent pre-described harmful effect on maxillary anterior fixed provisional prosthesis and provide comfort and satisfactory result during post-extraction healing period.

Anterior maxillary teeth play an important role in determining a person's first impression and facial profile. Implant surgery in esthetic area requires more careful diagnosis, treatment planning, surgery, and prosthetic restoration than in posterior area. To avoid complications in surgery and prosthetic restoration for implants in esthetic area, accurate diagnosis and appropriate case selection become very important. If you have decided to restore the area with implant prosthesis, you have to know exactly where to place an implant. I will discuss the ideal implant position in terms of mesio-distally, apico-coronally, labio-palatally, and implant angulation. And I would like to point out the selection of fixture diameter & length for anterior implant. Finally, a clinical implant prosthesis case in maxillary central incisor will be shown. In conclusion, for superior esthetic outcome in anterior implant prostheses, we must understand the patient's anatomic condition and know our ability.

In the maxillary anterior region, reconstruction of the localized alveolar ridge defect is very important in enhancing the esthetics of fixed partial denture. A 40-year-old female patient presented with a chief complaint of the inconvenience and unesthetic problem of 3-unit maxillary anterior prosthesis due to alveolar ridge resorption. After removal of old prosthesis, intraoral examination revealed moderate (buccolingually 4 mm) ridge deficiency in missing tooth region, leading to the diagnosis of Class I alveolar ridge defect. One of the reconstruction techniques to overcome this problem might be a technique that combines two types of soft tissue augmentation techniques. The purpose of this paper was to demonstrate the new combined technique of roll flap and combination onlay-interpositional graft utilized to acquire sufficient dimension of recipient area by one time of operation and to present the esthetic improvement of fixed partial denture by using this procedure in case of maxillary anterior localized ridge defect.

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.

Anterior tooth spacing is observed by pathological tooth movement (PTM), which is common in periodontal patients. And various occlusal factors contribute to PTM, especially in the maxillary anterior region, when there is excessive occlusal force, flaring due to position problem easily occurs. Teeth with loss of periodontal support tissue can secure stability when expanding the support area through intentional splinting, and change the occlusion when restored as a fixed prosthesis. After confirming the stable occlusion through the provisional prosthesis, it can be transferred to the final prosthesis through CAD-CAM. In this case, we present a long-term stable case through accurate diagnosis and treatment of the maxillary anterior teeth that have lost interdental contact.

In case of gingival recession and alveolar bone defects due to tooth loss for a long period of time in a single tooth in the maxillary anterior region, it is not easy to obtain aesthetic results with a single implant prosthesis. For aesthetic restoration, it is important to preserve hard and soft tissues through alveolar bone augmentation as well as restore harmony with adjacent teeth and soft tissues by placing the implant in an ideal location. In this case, an implant was placed using guided bone regeneration and a connective tissue graft simultaneously with immediate implantation after extraction from the maxillary anterior region where only residual root was left for a long period of time.

In a single implant restoration of maxillary anterior teeth, it is difficult to accomplish an aesthetic restoration of the implant prosthesis in the case of gingival recession and bone defect problems. To maintain aesthetic stability in the long term, it is important to place the implant in the ideal position as well as the recovery of the soft tissue and harmony with the prosthesis. Not only ideal implant position but also the harmony with surrounding soft tissues are important to fabricate aesthetic implant prosthesis for these cases. for these cases, a 47- years -old male with lowered level of osseous crest and gingival recession on maxillary anterior tooth was treated with guided bone regeneration and gingival recontouring.

The labio-palatal location of the implant in the maxillary anterior region is one of the important factors affecting the aesthetics of the implant prosthesis. However, the thin labial bone of maxilla could be absorbed in significant amounts after extraction of the teeth, which makes the implant be placed on the palatal side rather than the ideal location. In fact, in the cases of maxillary central incisor loss, UCLA was used for prosthetic restoration of palatally placed implant. In addition, with multidisciplinary treatment, GBR (Guided Bone Regeneration) was performed for compensating the absorbed alveolar bone and adjacent anterior tooth were aligned. Definitive restoration was performed after confirming aesthetic recovery of the gingiva with sufficient provisional restoration period. There were satisfactory results of functional and esthetic recovery of tooth loss through implant prosthesis.

Periodontal tissue destroyed by inflammation is difficult to achieve regeneration of the tissue and esthetic restorations only by surgical methods. In particular, improvement of esthetics is more difficult if the problem is related to the implant. A 23 year old woman suffered from unesthetic anterior implant prosthesis. According to her dental history, a repeated bone graft and soft tissue graft failed at a local dental clinic. It was needed to resolve the inflammation and to improve the esthetics. A free gingival graft and ridge augmentation accompanied by guided bone regeneration and a vascularized interpositional periosteal connective tissue graft was performed. Instead of implant prosthesis, a conventional fixed bridge was adopted for better esthetic result. The patient was satisfied with the esthetic conventional fixed prosthesis. This case report introduces esthetic rehabilitation of unesthetic implant prosthetics in the maxillary anterior dentition by a combination of surgical and prosthetic approaches.

For successful restoration of maxillary anterior implants, both pink esthetics and white esthetics must be satisfied. For pink esthetic part, the role of appropriate provisional prosthesis restoration is important, and for white esthetic part, the color and shape of the definitive prosthesis is important. Multilayer zirconia can be used for natural tooth appearance due to the higher transparency of the incisal area compared to the conventional monolithic zirconia. Therefore, in this case, white esthetic part was achieved through multilayer zirconia after recovering function and esthetics through appropriate provisional prosthesis in a patient who lost the maxillary anterior teeth.
