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.

Gradual attrition is a normal process of aging, but severe attrition causes occlusal disharmony, functional disorder and esthetic problems. The collapse of posterior support may cause attrition of anterior teeth, and loss of occlusal vertical dimension (OVD). And it induces the pathologic change of the TMJ, unaesthetic facial appearance and decreased masticatory function. In this case, 70 year-old male presented with decreased vertical dimension and esthetic problems due to worn dentition. Based on assessment of intraoral findings, diagnostic cast and radiographic examination, full-mouth rehabilitation with increase of OVD was planned. After 10 month follow-up, occlusal stability is maintained and through this procedure, satisfactory outcomes were achieved in esthetic and functional aspects.

Excessive occlusal wear results in unacceptable damage to the occluding surfaces, and can cause pulpal injury, occlusal disharmony, impaired function, and aesthetic deformity. Patients with severely worn dentition need to be classified as several categories relative to the vertical dimension of occlusion (VDO) and the interocclusal distance for the prosthetic space. When treating patients classified as those who have excessive wear without loss of occlusal vertical dimension but with limited space, we could consider treating them at an increased vertical dimension of occlusion. Treatments at an increased vertical dimension of occlusion may provide stability, given that the amount of its increase was minimal, and a perfected occlusion was achieved after enough stabilization period. A 50-year-old male visited the department of Prosthodontics in Yonsei University Dental Hospital with the chief complaint of worn teeth on lower anterior area. Reconstruction at an increased vertical dimension of occlusion was planned. After the compatibility of the new vertical dimension of occlusion had been confirmed under interim fixed restorations, definitive fixed restorations composed of full-contour monolithic zirconia prostheses were placed. This case presents that a satisfactory clinical result was achieved by restoring the worn dentition at an increased vertical dimension of occlusion with an improvement in esthetics and function.

The loss of posterior support and the abnormal jaw relation can cause pathologic findings. If deep bite patients with multiple missing teeth, can not have the stable posterior contact, the mandible moves posteriorly, and consequently the overjet and overbite get worse. And when the mandibular irregular occlusal plane is corrected, it is easier to have the bilateral balanced occlusion with the maxilla. So the treatment goal is to give proper posetrior support and establish appropriate anterior guidance, and ultimately provide improved mastication and esthetics recovery. In this case, a 68 year old man, having deep bite without posterior support was evaluated by the vertical dimesion decision flow-chart. An available prosthetic height, anterior occlusal relation such as overjet, overbite and the esthetic part such as facial height and the cephalometric analysis are the factors to be considered.

Patients who lost posterior teeth due to periodontitis or dental caries have collapsed vertical dimension, unstable occlusion and change of the mandibular position. In particular, patients in orthognathic surgery, clinician should re-establish the pre-operative stable position of mandibular condyle in articular fossa and favorable vertical dimension for high post-operative stability of mandible. Therefore, interdisciplinary approach and co-operation, including prosthetics, orthodontics, oral and maxillofacial surgeon, from diagnosis and treatment plan is important to get a good outcome. This case report was patients who had collapsed occlusal plane due to severe dental caries on maxillary molars with skeletal Class III malocclusion. Before orthognathic surgery, resetting of maxillary occlusal plane with temporary removable denture was performed. Then successful multidisciplinary approach was done and lead to acceptable clinical outcome.

The patient in this case was an 80-year-old female who had lost #16, 13, 26, 37, 36, 35, 44, 45, 46, 47 teeth. The patient showed loss of posterior support, loss of vertical dimension of occlusion, and deep anterior overbite. Her chief complaint was esthetic and functional discomfort. She wanted to restore normal facial aesthetic shape and masticatory function through prosthetic treatment. Clinical evaluation, radiographic examinations, and facial and oral analysis were performed. Interocclusal rest space was excessive than the average. Distance between labial vestibules and zenith of central incisors, and lower facial ratio were below the average. Taken together, occlusal rehabilitation was determined through increasing 4 mm of vertical dimension on premolars. In this case, a patient who lacked restoration space with deep bite in the anterior region due to loss of the posterior teeth support restored a stable occlusal relationship and harmonious anterior and lateral guidance through fixed and removable prosthesis with increased vertical dimension.

In the case of patients with pathological tooth wear, it is necessary to evaluate the loss of the vertical dimension. Setting the appropriate vertical dimension is important to rehabilitate the patient's stable intermaxillary relationship. A 77-year-old female patient's chief complaint was the pain of the mandibular incisors and the lack of molars. At the first visit, pathologic tooth wear of the mandibular incisors were observed. After diagnosis and evaluation, loss of vertical dimension was not observed, but insufficient intermaxillary space for prosthetic restoration was confirmed. Mandibular rehabilitation was performed with vertical dimension increase and this showed satisfactory results both functionally and aesthetically.
