Severe tooth wear may lead to pathological changes of pulp, imbalance in occlusion as well as functional and esthetic problems. In this case, 34-year-old male came to the hospital because of generally worn dentition due to attrition and erosion. After evaluation, a full mouth restoration with elevation of the vertical dimension of occlusion was planned. After occlusion was stabilized by an occlusal stabilization appliance, centric relation position was recorded and subsequent provisional restorations were fabricated. After evaluation, a CAD-CAM (computer aided design-computer aided manufacturing) prosthetic restoration was carried out using monolithic zirconia. After 12 months of follow up observation, the patient was satisfied with function and esthetic appearance.

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.

Gradual teeth wear is normal physiological progress, severe tooth wear can causes dysfunction, occlusal plane disharmony and esthetic problems. If additional space is needed for prosthetic restoration due to severe attrition, full mouth rehabilitation with increase of occlusal vertical dimension may be considered. In this case, 72 year old male patient with severe worn dentition, irregular gingival zenith and deep anterior bite was treated by full mouth rehabilitation for regaining the space for restoration, improving relationship and esthetic of anterior teeth. Provisional restoration obtained by systemic analysis, diagnosis and re-evaluation for a sufficient time was replicated to final restorations through double scanning technique using monolithic zirconia blocks. Satisfactory functional and esthetic outcomes were obtained.

Treating patients with severely worn dentition often requires comprehensive prosthetic treatments. Oral rehabilitation and long-term stability could be achieved by analyzing the cause of the wear and changing vertical dimension. The temporary restoration procedure is executed and patient's adaptation is evaluated by long-term observation when treatment is accompanied with increasing vertical dimension. In this case, 54 year-old male presented with worn dentition and esthetic dissatisfaction. In oral manifestations, severely worn dentition with attrition and erosion is diagnosed. To evaluate change of vertical dimension, interocclusal rest space, facial appearance, pronunciation, clinical crown length, distance from incisor edge to labial vestibule are evaluated. Consequently, 2.5 mm increase of vertical dimension that based on articulator incisal pin is determined. After 8 weeks stabilization period with temporary prostheses, definitive prostheses are fabricated. After 6 months follow up period, satisfactory outcomes were achieved both in functional and esthetic aspects through this procedure.

Aesthetic impression is emphasized in the recent field of implant restoration. However, there is limitation of creating proper shape of soft tissue as well as cervical emergence profile due to the use of pre-existing healing abutment in the process of initial post-operative soft tissue healing period. Designing the shape of abutment into the final customized abutment instead of its original shape helped to achieve more aesthetic implant restoration by applying healing abutment which could minimize the malposition and recession of soft tissue. In this study, soft tissue healing was promoted using the post-operative customized healing abutment and thereby obtained the result of more aesthetic and functional restoration by minimizing displacement of soft tissue in the process of applying final customized abutment.

Surgical extrusion, immediate extrusion following tooth luxation, is a method to preserve one's natural tooth and achieve esthetic restoration without additional periodontal surgery when subgingival dental caries or crown fracture occurs. A 16-year-old male was referred to the clinic from the department of operative dentistry for the esthetic restoration of maxillary left lateral incisor. Due to the crown to root fracture, the tooth was endodontically treated with a buccal crown length of 4 mm. When the palatal flap was elevated, the mesiopalatal cervical fracture area was situated 3-4 mm subgingivally. Crown lengthening was achieved through surgical extrusion. After 3 months of clinical observation and provisional restoration, the maxillary left central incisor was restored with all ceramic crown and obtained a satisfactory clinical result.

From the point of view of oral rehabilitation, the treatment of extensive tooth wear requires a prosthetic approach. Physiological tooth wear is considered as a normal process and generally does not require treatment, but excessive tooth wear causes problems like inadequate occlusion and esthetics. Changes of occlusal vertical dimension should be made through accurate diagnosis and analysis. Also, the patient's adaptation to the changed occlusal vertical dimension should be assessed over time. This case was a 60-year-old male patient who complained of a decrease in chewing function and esthetics due to severe tooth wear. Full-mouth rehabilitation was performed with a tooth supported fixed prosthesis. An occlusal stabilization splint and provisional restoration were used to evaluate the adaptation to increased occlusal vertical dimension and induce a stable centric relation position. After that, monolithic zirconia prosthesis was delivered. We report this as a satisfactory functional recovery and esthetics.

Dental injuries with crown fracture occur frequently, especially in young patient Reattachment of the crown fragment has been shown to yield good esthetic results in that original tooth anatomy is restored with a material that abrades at a rate indntical to that of the adjacent tooth substance and at the same time permits continual monitoring of pulpal status through the fragment. Case 1 was complicated crown fracture with pin-point bleed ing, that was treated by direct pulp capping with calcium hydroxide and fragment reattachment. Case 2 was in trusive luxation with complicated crown fracture and was treated by pulp treatment and fragment reattachment. Case 3 was uncomplicated crown fracture, and fracture line involved slightly biologic width and treated by reattachment of the crown fragment.

Materials that can be use in CAD/CAM are composite, ceramic, hybrid and metal. Among the available materials, monolithic ceramic technique which is the manufacturing technique using one type of the materials is mainly used in a dental office. It is the technique where final tooth-shaped prostheses are made from the material block and used after polishing or applying heat and that does not require traditional ceramic build-up process. Although shot of esthetic quality, because manufactured within 1 hour the monolithic ceramic technique has advantages such as that treatment can be completed in one day and in one time visit, that stability of the material is high because there are low possibility of distort by not melting and phase transformation, and that it can be easily worked in the office with computer assisted devices. We classified the materials that can be used in this technique based on their generations from clinical stand point.

Various techniques have been developed, and the development of piezo electric devices have made it possible to widen the alveolar ridge even if the residual bone is dense or if there is a lack of cancellous bone between the cortical bones. In the operation of the mandibular posterior area, the flap is easily accessible to the ramus bone, from which high quality autogenous bone can be obtained, compared to other parts. A small autologous bone block can be used with particulated bone graft material using one screw for bone regeneration instead of a large autologous bone with two screws. The tapered implant design can minimize buccal bone fracture, even in severely atrophic mandibular areas. We report a case of 4 years following implant placement with ridge splitting and small autogenous bone graft in severly atrophic mandible. This report demonstrates a case of functional and aesthetic restoration in a patient through a collaboration.
