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.

치관부 파절이나 치아결손 혹은 치아형태의 이상이나 변색된 치아등으로 보철치료가 요구되는 경우 저작, 연하, 발음등의 회복과 심미적인 회복이 중요한 목적이 되며, 전치부에서는 심미성이, 구치부에서는 기능적인 회복이 더욱 강조된다. 보철치료후 치료목적을 달성하고 건강한 구강내의 상태를 유지하기 위해서는 보철물이 지대치 및 주위조직에 생물학적으로 조화되어 병적상태를 유발시키지 않아야 하며, 이를 위해서는 시술전에 올바른 진단과 적절한 치료계획을 세우고, 지대치 형성, 인상채득 및 임시관 장착, 금속관 및 가공의치 제작, 구강내의 시적(try-in), cementation등 모든 과정을 주위조직과 관련하여 주위 깊게 행하여야 한다.

Interim immediate denture is fabricated to minimize the period of edentulousness after removal of the patient's remaining teeth and before delivery of final prosthesis. In the case of using the CAD/CAM system, there is an advantage in that the manufacturing process in the clinic and laboratory can be simplified by overcoming some of the limitations of manufacturing interim immediate dentures in the traditional way. However, there are also disadvantages in that errors occur in the process of transmitting information about the patient's intermaxillary relationship to the digital network of the laboratory, resulting in unstable occlusal relationships or non-esthetic prostheses. To overcome this problem, using the simple and accurate POP BOW system's occlusal plane digital transfer method, it was possible to fabricate an esthetic and functional 3D printed interim immediate denture after removal of the remaining upper and lower anterior teeth.

A crossed occlusion resulting from the presence of posterior teeth in one arch but no opposing teeth in the opposite arch results in collapse of the vertical dimension. In this case, the patient has a class III malocclusion with crossed occlusion and anterior crossbite. In order to evaluate the proper vertical dimension, provisional denture was used to stabilize the vertical occlusal dimension for 3 months. After, provisional fixed restoration was used for the stabilizing occlusal relationship and aesthetic improvement for lip support. Definitive prosthesis in implants in the mandible and abutments in the maxillary were using Porcelain-fused-to-metal crown (PFM) crown and the maxillary unilateral edentulous area was treated with removable partial dentures. Through this, proper support of the posterior region and normal anterior occlusal relationship were formed, and the patient was able to obtain aesthetically and functionally satisfactory treatment results.

As implant can be covered by National Health Insurance Service (NHIS), it was increased the interest in the removable partial denture (RPD) with the surveyed fixed prosthesis supported by implant fixture. To achieve predictable result, it needs the prudent implant planning by basic principles of RPD and patient's residual ridge. This 67 years old age male had a few unilateral remaining teeth, and hoped the treatment covered by NHIS. As using CAD software, the position of implant is planned with regarding to occlusal table of provisional denture, basic principles of RPD, and resorbed residual ridge. The definitive prostheses can ensure the stability and retention of removable prosthesis. When planning implant fixed prostheses, the digital technique was utilized to consider basic principle of RPD and resorbed residual ridge. As a result, it provided satisfactory prostheses.

The long-term use of an implant overdenture shows problems, such as wear of attachment, concentrated occlusal forces on the anterior teeth, fracture of artificial teeth and rotation of denture. By transitioning to an Implant-assisted removable partial denture (IARPD) using additional implant placement, the problems can be solved. In this case report, a transition was made from implant overdenture to IARPD utilizing surveyed crowns to distribute occlusal forces concentrated on anterior teeth and to prevent denture rotation in a skeletal Class III patient. Design of definitive prosthesis with appropriate function and aesthetics was determined through several stages of provisional restorations. In this case, appropriate posterior occlusion and maintenance of peri-implant bone level of definitive prosthesis were observed.

Installation of dental implants at optimal angles and positions is critical in long-term stable implant-supported restorations. Surgery and prosthodontic procedures should be performed accurately as the treatment is planned. In this clinical case, Computer aided design and manufacturing technology was used not only to establish a precise surgical plan, but also to fabricate both provisional and definitive fixed prostheses. A surgical guide was designed to install the implants at proper positions for the definitive prostheses. The patient's esthetic information, which was necessary for the new provisional and definitive fixed prostheses, was obtained from the existing temporary dentures. Finally, the complete mouth fixed implant-supported rehabilitation using monolithic zirconia provided the patient with functionally and esthetically satisfactory prostheses.

In this case report, an alternative impression technique for fabricating removable partial dentures was used in a patient with very few remaining teeth. In this technique, an individual tray was made on the cast, which was made by relining interim denture and taking overimpression with irreversible hydrocolloid according to McLean's functional impression concept. This method showed the following advantages: the no need for border molding with modeling compound, time saving for denture impression without overextension and accurate seating of the individual tray.

To obtain denture retention, support, and stability in Class III edentulous cases with flat alveolar ridges and extensive flabby tissue is very difficult. The patient was a 72-year-old male who wore ill-fitting 20 year old dentures made by non-medical institutions. There was flabby tissue on the maxillary anterior ridge. The patient showed Angle Class III skeletal relationship with severe protruded mandible. First, temporary dentures were fabricated to restore the masticatory function, and final dentures were made through non- pressure impression technique and careful the arrangement of the posterior resin teeth. Improvement of the retention and stability of the denture during the occlusal force application is reported.

A three-dimensional (3D) intraoral scanner, which is one of the major developments in digital dentistry, is widely used in fixed prosthodontics. The application of intraoral scanner is now increasing in removable prosthodontics. Sclerotic change induced by scleroderma causes the limitation of mouth opening and multiple loss of the teeth. Conventional prosthodontic procedures are challenging for patients with this disease. This study showed a case of digital approach to the removable prosthodontic treatment of a patient who had the scleroderma and the consequent microstomia. At the provisional stage, the optical impression of patient's oral structures was digitally obtained. Using a 3D printer, the provisional dentures were fabricated. After extraction of hopeless tooth, the definitive digital impression was taken and the metal frameworks were fabricated, based on the data acquired from the impression. The definitive removable partial dentures were completed and delivered to the patient, who was satisfied with the prostheses.
