Implants can not only be used in the definitive prosthetic solution but can also be of great benefit as stable anchors during orthodontic therapy. However, for ideal results, it is essential to establish orthodontically favorable positions for the implants and, more importantly, the best position for an adequate occlusal restoration prior to orthodontic teeth movement.<br/>This report describes the utility of implants for bite raising and occlusal support prior to orthodontic teeth movement in patients with a reduced occlusal vertical dimension and resultant flaring.<br/>The patient was a 57-year-old woman with chronic periodontitis including resultant flaring of the maxillary anterior teeth and posterior bite collapse. She first received periodontal treatment using a bilateral free-end-saddle removable partial denture, however, she complained of maxillary anterior flaring after placement of the denture and wanted orthodontic treatment and implant therapy. Therefore, the degree of potential bite raising and the stability of the mandibular position after bite raising were checked by an anterior jig and Gothic arch. Possible positions of implant placements and orthodontic tooth displacement were determined using a wax setup cast and lateral cephalograms with an anterior jig. Nine implants were placed in the planned positions using a surgical stent. Consideration of possible future orthodontic tooth displacements and the stability of the mandibular position before treatment is essential for determining the best placement positions for implants. Implant-supported occlusions in orthodontically favorable positions provide patient satisfaction, such as the reduction of periodontal pockets, esthetical restoration and stable occlusion.<br/>It is suggested that the use of implants prior to orthodontic teeth movement is effective for stable bite raising and occlusal support in patients with a reduced occlusal vertical dimension and resultant flaring.
