This clinical report describes an orthodontic-prosthodontic interdisciplinary treatment for a patient with multiple missing teeth and unilateral scissors bite. A 47-year-old female presented with multiple missing posterior teeth, anterior large overjet, deep bite, and posterior scissors bite on the right premolar area. Periodontal therapy was performed and followed by orthodontic treatment. The maxillary anterior teeth were initially aligned, then two implants were placed for the left mandibular molars to increase occlusal vertical dimension. The scissors bite between the right maxillary and mandibular premolars were corrected using the miniscrews as an anchorage. Other implants were placed for the right maxillary and mandibular molars after the occlusal planes and occlusal relationship were harmonized. The patient adapted well to altered vertical dimension without any specific problems including peri-implant marginal bone loss. Interdisciplinary approach resolve the complex orthodontic-prosthodontic problems and concluded in successful results.

Adjunctive orthodontic therapy may be required to create appropriate space, to address misalignment and tooth size discrepancy for better function and esthetics. The desired interproximal alveolar contour and gingival embrasure form can be developed during treatment. Various applications of temporary anchorage devices for pre-prosthetic tooth movement allowed clinicians to achieve high efficiency, shorter treatment time, and less discomfort of patient. Biomechanical considerations for the periodontal status of the affected teeth are required to successfully control the vertical and horizontal space. Hence, the interdisciplinary approaches have an essential role in maximizing the favorable treatment outcome. In particular, pivotal Clinical decisions such as whether to open or close the space should be made by consensus of the involved dentists. This article presents the orthodontic treatment approaches for prosthodontic works including mesiodistal and vertical space regaining specially for cases of unrestored teeth over an extended period of time.

A tooth solely can not be an exclusive factor to attain our goal, esthetics. Other consideration, such a proportion of individual tooth, harmonized arrangement of the dentition and surrounding tissues including gingiva, lip and face should be taken into account. Esthetic gingival pattern and incisal level in the anterior area are the very important factors for esthetic restoration of the smile. We often propose adequate periodontal and prosthodontic approaches in order to improve the esthetics of the anterior area. Here, I would like to share some cases which include soft tissue management for ovate pontic placement, osteoplasty, resin filling for severe cervical caries, and bleaching approach to discolored root caused by endodontic treatment, and so on.

Occlusal disease is comparable to periodontitis in that it is generally not reversible. Occlusal disease, however, like periodontitis, often maintainable. It does itself to treatment and when restorative dentistry is utilized it becomes, in that sense, reversible. Moreover, a systematized and integrated approach will lead to a prognosis that is favorable and predictable. This approach facilitates development of optimum oral function, comfort, and esthetics, resulting in a satisfied patient. Such a systematized approach consists of four logical phase : (1) patient evaluation, (2) comprehensive analysis and treatment planning, (3) integrated and systematic reconstruction, and (4) postoperative maintenance. An integrated treatment plan is first developed on one set of diagnostic casts, properly mounted on a semiadjustable articulator using jaw relationship records. This is accomplished by using wax to make reconstructive modifications to the casts. These modified casts become the blueprint for planned occlusal changes and the fabrication of provisional restorations. The treatment goals are : (1) comfortably functioning temporomandibular joints and stomatognathic musculature, (2) adherence to the basic principle of occlusion advocated by Schuyler, (3) anterior guidance that is in harmony with the envelope of function, (4) restorations that will not violate the patient's neutral zone. This report shows the treatment procedures for a patient whose mandibular position has been altered due to posterior bite collapse. Migration of the maxillary anterior teeth had occurred, and the posterior occlusal contacts showed pathologic interference. Precise diagnosis using mounted casts was executed and prosthodontic reconstruction by the aid of an unconventional orthodontic correction on maxillary flaring was planned. An unconventional orthodontic correction can be accomplished by using preexisting natural teeth, which can be modified for use in active tooth movement or splinted together for orthodontic anchorage. This technique has an advantage over conventional fixed appliance orthodontic therapy because it can accomplish tooth movement concurrently with restorative and periodontal therapy. On occasion, minor tooth movement can be necessary to achieve the optimum occlusal scheme, crown form, and tooth position for the forces of occlusion to be displaced down the long axis of the periodontally compromised teeth. Once the occlusion, periodontal health, and crown contours for the provisional splinted restoration are acceptable, the final splinted restoration can be similarly fabricated, and it becomes an excellent orthodontic retainer.

Tooth wear, one of the physiological changes in the elderly patient's mouth, generally does not require treatment, but requires prosthodontic restoration when occlusal disharmony, poor masticatory function, pulp exposure occurs. One of the primary considerations in prosthodontic restoration for tooth wear is vertical dimension. It is necessary to make an accurate diagnosis and analysis, correct judgement of the interdental relationship for predictive treatment plan. A step-by-step approach considering dental care for aged is also required. In this case, a 93-year-old male patient presented with worn dentition and mobility of existing fixed dental prosthesis. After diagnosis and evaluation, maxillary rehabilitation without any change in the occlusal vertical dimension was performed and this shows satisfactory results both functionally and morphologically.

The prosthodontic treatment of severely resorbed edentulous patients has been one of the frustrating areas due to extensive loss of tissues. The integrated neuromuscular balance among tongue, lip, and cheek is compromised. The retention, stability, and support are the three major factors to influence the clinical outcome. Fish described a denture as having three surface, with each surface playing an independent and important role in the over all fit, stability, and comfort of the denture. He recommended that the polished surface should be a series of inclines so that pressure from muscular activity will retain dentures. Within the denture space there is an area that has been termed the neutral zone. The neutral zone is that area in the mouth where, during function, the forces of the tongue pressing outward are neutralized by the forces of the cheeks and lips pressing inward. According to Jacobson and Krol, neuromuscular control interacts to provide retention and the relationship of polished surface of denture base to the surrounding muscular structure of orofacial capsule facilitates the stability and retention. This neutral zone concept has been demonstrated with various modification by a number of authors. The theory used to develop the denture base contours is based on the belief that the muscle should functionally mold not only the border but the entire polished surface. Lott and Walsh reported the clinical success on complete mandibular dentures with application of neutral zone concept. A number of studies demonstrated that denture stability and retention are more dependent on correct position of the teeth and correct contour of external surfaces of the denture in a severely resorbed alveolar ridge. This article presents a prosthodontic approach to treatment of a edentulous patient using neutral zone technique to improve the retention and stability of the prosthesis.

Fusion of teeth is a developmental anomaly. It occurs at the stage of tooth formation, which determines the shape and size of the tooth crown, when one or more teeth fuse at the dentin level during the morphodifferentiation of the dental germs. Such teeth show macrodontia and may cause crowding, as well as esthetic and endodontic problems. In this article, we report a rare case of a maxillary central incisor fused to a supernumerary tooth showing labial and palatal talon cusps, which was orthodontically moved across the midpalatal suture. A 13-year-old Caucasian boy sought treatment for the unesthetic appearance of his maxillary central incisor and anterior crowding. He was rehabilitated successfully via a multidisciplinary approach involving orthodontic, nonsurgical endodontic, periodontal, and prosthodontic treatments. After a 26-month treatment period, the patient's macroesthetics and microesthetics were improved. The overall improvement of this macrodontic tooth and its surrounding tissues through multidisciplinary treatment was documented using cone-beam computed tomography.

Mandible fractures belong to the most common fractures encountered in maxillofacial trauma. Because mandible is such a unique structure with hinge joint and masticatory muscles attached to the body of mandible, attention must be paid to avoid displacement during treatment. Displacement during fracture reduction leads to malocclusion. Many TMJs function with complete comfort and apparent normalcy in adapted centric posture, even though they have undergone deformation caused by trauma. This clinical report describes the patient with post traumatic malocclusion and its prosthetic treatment. His fractured mandible was openly reduced in changed position, as a result his occlusion has been changed. He was treated by prosthetic method in so-called adapted centric posture.

Ectodermal dysplasia is characterized by a partial or complete lack of primary and permanent teeth, other ectodermal structures that may be affected include the skin, hair, and sweat glands. The patient with the so-called anhidrotic type of ectodermal dysplasia exhibits dry skin, lack of sweat glands, sparse eyebrows, body hair, saddle nose, and everted lips. Genetic basis of anhidrotic ectodermal dysplasia is recessive and sex-linked, being manifested chiefly in males, but this is debatable. A 6-year-old boy, with typical signs of anhidrotic ectodermal dysplasia, was presented. Prosthetic restoratoins are of great value to these patients, both from the standpoint of function and for psychologic reasons. The need for complete denture is critical during preschool periods and continues into adulthood. The following case report is an approach to the management of a patient with anhidrotic ectodermal dysplasia.

With the understanding of tooth crown biomechanics and the progress of dentin adhesives, bonded porcelain restorations including a porcelain laminate veneer present an extended spectrum of indications for anterior teeth. Porcelain laminate veneer as a restoration offers the conservative solution that balances the functional and esthetic needs of the anterior dentition. Porcelain's stiffness, its surface characteristics, and the biomechanical strength achieved through bonding to tooth surface enable the restoration of the tooth as a whole supporting occlusal force and masticatory function. Namely, the optical effects inherent in the tooth and the lifelike features of the porcelain make that this restoration approaches the ultimate in esthetic satisfaction for both the dentist and the patient. A 49-year-old female patient with the incisal discoloration of upper central incisors and black triangle between the central incisors was referred to correct her esthetic problems with prosthodontic approach. The patient was satisfied with two porcelain laminate veneers that were made according to prof. Magne and Belser's recommendation.
