This is a case of a patient (age 60, female) with mandibular bilateral free end missing, involving partial anterior crossbite, where functional recovery was eventually achieved by occlusal reconstruction using partial denture. In such cases, provision of the anterior coupling by orthodontic treatment and recovery of occlusal support by implant would be the standard approach. However, as per the patientʼs request, the second best solution was applied, namely, morphological correction of anterior teeth by crown prostheses and occlusal reconstruction by replacing mandibular bilateral free end space with partial denture using the altered cast technique to revise the stress distribution and the tissue displacement over alveolar ridge mucosa and support tooth. Provisional restorations based on diagnostic wax-ups were fitted, and the appropriate mandibular position was explored by trial and error. Second provisional restorations confirmed posterior disclusion during forward and lateral movements on a semi-adjustable articulator, so the final prostheses were duly fabricated and set. As of 6 years follow up of the setting of the final restoration, the ceramics chipping of the maxillary anterior teeth was occurred, however, the patient has not complained of any problems. During six year followup, chipping was observed in the ceramics of the maxillary anterior teeth, but the patient presented no complaint.
