Abstract
The rehabilitation of edentulous jaws with severe bone resorption represents a clinical challenge. Among the available therapeutic options, guided bone regeneration (GBR), complemented by precise digital planning, can help create more favorable conditions for implant placement and subsequent prosthetic rehabilitation. Following tooth extraction, substantial alveolar bone loss can occur during the first six months, progressively altering the intermaxillary relationships. We report the case of a 59-year-old female patient with a Seibert Class III defect in the anterior maxilla, a pseudo-skeletal Class III intermaxillary relationship, and stage III, grade C periodontitis. Alveolar ridge preservation was performed in the posterior maxillary sites, and GBR using the tent-pole technique was carried out in the anterior sector with a combination of xenograft, allograft, and autograft covered by a porcine collagen membrane. Implant planning followed a dual-scan cone-beam computed tomography (CBCT) protocol. Baseline and nine-month CBCT superimposition revealed regional dimensional changes: in the ridge-preservation sites, a mean crestal resorption of 1.55 mm at 1 mm from the crest coexisted with an apical gain of 0.86 mm at 5 mm; in the tent-pole area, a horizontal increase of up to 3.36 mm was observed, with concomitant vertical loss. In the mandible, a xenograft alone was associated with favorable osseointegration of the subsequently placed implant. Prosthetically guided planning articulated the surgical and prosthetic phases and allowed completion of rehabilitation with an implant-retained, bar-supported overdenture. Long-term functional and esthetic evaluations remain ongoing. Within the limitations of a single case, the combined regenerative and digital workflow was associated with clinically favorable outcomes.
