Abstract
Loss of intermaxillary relations due to wear or carious destruction of tooth crowns is an everyday problem in prosthetic therapy. As a rule it includes long-term oral rehabilitation with splints, and in situations with a maintained supportive segment fixed prosthetic therapy with inlays, onlays, crowns and bridges. In extreme situations contact between the maxillary and mandibular alveolar ridge can occur. A case is presented of implantoprosthetic rehabilitation in bilateral loss of intermaxillary space as a result of long-term carious destruction of teeth crowns, with maintained intermaxillary relation in the intercanine segment. In cooperation with a specialist in dental prosthetics, a plan of therapy was drawn up, based on the maintenance of existing intermaxillary relations. Therapy with a bite splint would have involved change in the intermaxillary angle, and was therefore abandoned because of the need to maintain the existing vertical dimensions of occlusion in the intercanine segment. Following conservative treatment of the remaining teeth, in the intercanine segment, intermaxillary relations were registered, OPG of the patient was digitalised and the height of the alveolar ridge measured by specially developed software (Dentist 1.1. Pelsys, Croatia). Measurement confirmed that reduction of the alveolar ridge by 7-9 mm in the area of the right first premolar up to the first molar, and 4-7 mm in the area of the left first premolar up to the first molar, would ensure sufficient space for a fixed prosthetic restoration, without endangering integrity and biomechanics of the lower jaw. Extraction of the remaining teeth roots was performed bilaterally in the mandible, and levelling of the alveolar ridge of the mandible. At the same time two implants each were implanted on place 34 (length 9.5 mm, diameter 3.5 mm), 36 (length 9.5 mm, diameter 4.5 mm), 44 (length 9.5 mm, diameter 4.5 mm) and 46 (length 9.5 mm, diameter 4.5 mm). After a period of osseointegration of 4 months a fixed prosthetic restoration was fabricated with which the patient’s habitual intermaxillary relation was retained.
