title: "Tent-Pole" for Reconstruction of Large Alveolar Defects: A Case Report.
abstract: Severe tridimensional alveolar ridge defects complicate the placement of dental implants, and surgical removal of some oral tumors might not leave adequate bone for dental implant placement. Regenerating an adequate amount of bone vertically and horizontally to achieve a satisfying outcome for well-osseointegrated implants and thus ensure long-term success of implant restoration is challenging. This report describes the clinical feasibility of a simple approach using a screw tent-pole combined with guided bone regeneration to augment complicated tridimensional alveolar ridge defects in a case of extensive bone loss due to maxillary tumor surgery. Titanium screws were arranged in "tented" fashion to provide stable room for bone regeneration. Regenerated bone was achieved and 2 more implants were placed in the regenerated ridge 10 months later, leading to a successful maxillary prosthesis.
