  • Loss of molar support and abnormal jaw relationship lead to occlusal disharmony and cause pathologic signs. Full mouth rehabilitations with reestablishment of occlusal schemes are needed. In this case, the 75 year-old female patient showed posterior bite collapse, irregular occlusal plane and Class II jaw relationship. By observing her profile and interocclusal distance, she was diagnosed as loss of occlusal vertical dimension. Treatment plan is to restore maxillay class I removable partial denture and mandibular fixed prosthesis and to establish vertical dimension and harmonious occlusal plane. Occlusal vertical dimension of 19 mm, which is obtained by 7.5 mm increase between maxillary right lateral incisor and mandibular canine, was established using temporary prosthesis via diagnostic wax-up. Patient adaptation with newly formed vertical dimension was verified during 8 week follow-up period. Within the information of interim prostheses, final restoration was constructed and delivered. The patient showed sound occlusal scheme and esthetic profile.

  • A proper vertical dimension and a harmonious occlusal plane are essential to satisfy a patient esthetically and functionally. A maxillomandibular occlusal vertical dimension is determined by the elevators which repeatedly contracts to a certain length, and a tooth location is determined by a maxillomandibular vertical dimension. The patient of this case came in with the incongruity of the lips and the occlusal plane. The result of clinical test showed the lack of length of the lower anterior due to the reduction of vertical dimension, the deep overbite of anterior, the excessive attrition of anterior, and the incongruity of occlusal plane. After the diagnostic wax-up, the temporary restoration was installed, and final prosthesis was installed after 6 months. As a result, the patient obtained a functionally and esthetically satisfying result.

  • Full-mouth rehabilitation with increasing vertical dimension can be used for patients with severely worn teeth. In severely worn teeth also, the alveolar process can be elongated to compensate for the reduced vertical dimension, and the patient's vertical dimension of occlusion can be kept constant. However, full-mouth rehabilitation with increasing vertical dimension must be carefully chosen, because the vertical dimension can be reduced by tooth wear. It is important to establish a treatment plan with the systematic diagnosis of the change in the vertical dimension and gain space for the prosthesis. It is necessary to change the vertical dimension to secure the restoration space and select the minimum vertical dimension elevation for the esthetic and functional goal. In this case report, the patient complained of difficulty during chewing due to a worn dentition and wanted esthetic improvement of the short mandibular anterior teeth. After systematic evaluation and diagnosis, we performed full-mouth rehabilitation with minimum vertical dimension elevation to obtain the space for restoration. This resulted in a stable and harmonious occlusion, and the functional and esthetic problems of the patient were solved after treatment. The patient was satisfied with the results of the treatment and maintained stable occlusion during the follow-up period.

  • The loss of posterior occlusal support due to tooth loss is likely to lead to compensatory protrusion and labial tilt of the anterior teeth, which may be accompanied by a deep bite and a decrease in vertical dimension. The patient may suffer from a decrease in masticatory efficiency, inaccurate pronunciation, facial appearance changes, and temporomandibular joint disorder, so stable occlusal formation with support of posterior occlusion and restoration of vertical dimension is necessary. We report the case of a patient with reduction of vertical dimension, and inaccurate pronunciation due to multiple tooth loss who underwent full mouth rehabilitation with increased vertical dimension accompanied by phonetic analysis and achieved satisfactory functional and aesthetic results.

  • This study was investigated to assess the difference of facial height and occlusal plane inclination between pre- and post-treatment in Class I malocclusion group The subjects consisted of 35 extraction patients and 30 nonextraction patient,;, and was subdivided into Group I(overbite<0mm), Group II(04mm) in reference to overbite, and adolescent group and adult group in reference to age. Lateral cephalogram was taken with standard method, traced, and digitized for each subject. The computerized statistical analysis was carried out with SAS program The results wolf as follows. 1. In both groups of extraction and nonextraction group the anterior facial height increased after orthodontic treatment but there was no significant difference(p>0.05) between each goup. 2. There was no statstical significance in change of occlusal plane inclination in adolescent group, but significant difference(p<0.05) among three subgroup in adult group. 3. In adolescent-extraction and adolescent-nonextraction group there was significant increase of anterior facial height and posterior facial height, and was superior to adult groups in posterior facial height increment. 4 In all groups upper and lower molars were uprighted to occlusal plane. This had statistically significant effect.

  • Loss of permanent molar by multiple dental caries traumatic influence or hereditable disease can cause loss of the vertical dimension in children. However traditionally reconstructive treatment to restore vertical dimension in children has been provided by using simple methods such as celluloid crown form and stainless steel crown. The presented case report describes an alternative treatment modality of vertical dimension by using removalbe appliance This appliance is made with average of facial height and maximal clenching force by using T-scan.

  • Although not all kinds of deep bite occlusions are considered pathological states, they can cause persistent wear and eruption of the anterior mandibular teeth if the anterior occlusal contact is unstable or accompanied by an occlusal disharmony. The patient was a 72-year-old man with no occlusal contact of the remaining anterior teeth in the centric relation position because of a skeletal class II malocclusion and loss of occlusal support. If the vertical dimension needs to be increased for prosthetic restoration in a patient with a deep bite, the amount of vertical dimension increase must be determined through precise diagnosis. This is because the overjet may increase and cause an unstable occlusion. In this review, we report the case of a patient with a stable occlusion and good treatment results achieved by using a removable partial denture prosthesis and applying the Dahl concept.

  • Deep overbite patients who do not have proper occlusal relationship may cause problems such as teeth wear and antagonist extrusion. These lead to the collapse of occlusal plane and esthetic problem. Increasing vertical dimension is frequently essential to resolve those problems. This case report demonstrates a full-mouth rehabilitation for a patient with severe deep bite that contacts surface to surface by increasing vertical dimension. Treatment procedures included diagnosis, treatment planning, implant surgery, and prosthodontic rehabilitation. Satisfactory results were obtained in functional and esthetic aspects.

  • 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.
