Occlusogram-Guided Interdisciplinary Planning in Implant Dentistry and Orthodontics for Oral Rehabilitation

A 65-year-old female patient with stable periodontal status, anterior crossbite, mandibular spacing, and need for posterior implant rehabilitation was treated using an occlusogram-guided interdisciplinary approach. The increasing demand for complex oral rehabilitation has reinforced the need for effective interdisciplinary planning between orthodontics and implant dentistry. In such cases, dental implants may serve not only as prosthetic units but also as sources of absolute anchorage during orthodontic treatment, requiring precise preorthodontic positioning. This case report describes the use of an occlusogram-guided approach to optimize implant placement and coordinate orthodontic mechanics. Digital occlusograms were constructed using GeoGebra (International GeoGebra Institute, Linz) from occlusal photographs of dental casts calibrated to a 1:1 scale, allowing simulation of planned tooth movements in the transverse and sagittal planes and visualization of the final occlusal relationships. This approach enabled the determination of implant position based on the predicted posttreatment arch form, the required interproximal spacing, and the anticipated occlusal relationships. A mandibular implant was placed prior to orthodontic treatment, and after an eight-week osseointegration period, was successfully used as anchorage for posterior mesialization through a preactivated lingual arch. Treatment resulted in complete mandibular space closure (8 mm), correction of maxillary midline deviation (2 mm), establishment of bilateral Class I canine relationships, and functional occlusal integration. The implant was subsequently maintained for definitive prosthetic rehabilitation. The occlusogram also served as an effective communication tool among clinicians and facilitated the informed consent discussion by providing a visual representation of planned treatment changes. This report illustrates the clinical application of occlusogram-guided interdisciplinary planning and demonstrates its potential value in facilitating precise implant positioning and coordinated treatment sequencing in complex orthodontic-implant cases.
