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.

Teeth wear and extrusion of antagonist are commonly observed in deep bite patient having severe vertical and horizontal overlap. These problems cause collapse of occlusal plane and abnormal anterior guidance. Without restoring harmonious occlusion, loss of multiple teeth and decreased masticatory function could not be prevented. To resolve problems associated with deep bite, multidisciplinary treatment including oral surgical, orthodontic and prosthetic treatment should be performed. This clinical report describes the results of increasing occlusal vertical dimension with a full-mouth restoration procedure. The treatment procedures include extraoral and intraoral examination, diagnosis, treatment planning, diagnostic wax-up, segmental osteotomy, orthodontic intrusion and prosthodontic rehabilitation. Full mouth rehabilitation with increasing occlusal vertical dimension can solve esthetic and functional problems.

The collapse of the posterior occlusion destroys the normal occlusal plane and causes excessive wear reducing the vertical dimension. Reduced vertical dimension of occlusion causes not only aesthetic and functional problems but also overloading on the temporomandibular joints and abnormalities of muscle nerve system. In order to improve the collapsed occlusal relationship, it is necessary to consider the change of the vertical dimension. It is necessary to make a precise diagnosis and analysis before the treatment and to evaluate the adaption of patient to the new vertical dimension of occlusion. A patient with excessive overbite often has occlusal problems of tooth wear and tooth eruption. Considering these considerations, overall prosthodontic restoration is required to solve the problem. A patient of 68 year old man in this case who suffered major tooth wear and maxillary posterior teeth loss was treated with elevation of vertical dimension of occlusion by maxillary removable dental prosthesis and mandibular fixed prosthesis.

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.

Excessive tooth wear can cause irreversible damage to the occlusal surface and can alter the anterior occlusal relationship by destroying the structure of the anterior teeth needed for esthetics and proper anterior guidance. The anterior deep bite is not a morbid occlusion by itself, but it may cause problems such as soft tissue trauma, opposing tooth eruption, tooth wear, and occlusal trauma if there are no stable occlusal contacts between the lower incisal edge against its upper lingual surface. The most important goal of treatment is to form stable occlusal contact in centric relation. In this case report, patients with decrease in vertical dimension and anterior deep bite due to maxillary posterior tooth loss and excessive tooth wear were treated full mouth rehabilitation with increased vertical dimension to regain the space for restoration and improve anterior occlusal relationship and esthetics. The functional and aesthetic problems of the patient could be solved by the equal intensity contact of all the teeth in centic relation (CR), anterior guidance in harmony with the functional movement, and restoration of the wear surface beyond the enamel range.

Loss of posterior bite support might cause unstable occlusal relationship and when the mandible slides forward in the centric or habitual occlusion, excessive load is applied to the anterior region followed by causing the occlusal plane to collapse or leading to a decrease in occlusal vertical dimension. In addition, disorder of temporomandibular joint function may occur. The inter-dental arch discrepancy causes a mismatch in the vertical and horizontal overlap of the anterior and posterior regions. The deep bite in the anterior region and the scissor bite in the posterior region cause unstable occlusal contact and insufficient occlusal contact area. This report was to rehabilitate a patient with above-mentioned complex problems. Physiologic adaptation to increased vertical dimension and new occlusal plane were evaluated using provisional prostheses, and definitive prostheses was fabricated using cross-mounting technique. Stable occlusion, harmonious teeth overlap and adequate occlusal plane were established, so functionally and aesthetically satisfactory results are obtained.
