Additional Details

This patient presents with periimplantitis of the lower left quadrant. Removal of existing implants with Guided Bone Regeneration is required. The tent pole technique for GBR was used.

A Buccal flap with releasing incisions and a Lingual flap with dissection of the mylohyoid muscle was necessary to achieve primary closure without tension. 100% autologous bone was collected with the bone scraper.

Tent pole screws (Tenting Screw Kit) with adequate height and angulation were placed to provide support for collected autologous bone to regenerate in the horizontal and vertical defects caused by the periimplantitis .

A long lasting (6 months) resorbable collagen membrane was adapted and stabilized with membrane screws.

Flaps were closed primarily and free of tension with horizontal mattress sutures (PTFE 3.0), and coronally with 3.0 Chromic Gut sutures.

Implants will be placed in six months. A connective tissue graft will be required to increase keratinized gingiva around the implants which can be completed at the time of implant placement, or at the time of uncovering the implant.

Bone regeneration of large maxillary and mandibular alveolar ridge defects is clinically challenging. Various techniques have been described for the reconstruction of these deficiencies before implant placement. The tent screw-pole technique is one of the effective methods available for clinicians to perform the predictable functional and esthetic reconstruction.

The tent screw pole technique is one of the methods available for practitioners to perform horizontal ridge augmentation to facilitate dental implant placement. The purpose of this study was to evaluate the efficacy of the tent screw pole technique for horizontal ridge augmentation and to compare the results with those of the tunnel technique and open ridge augmentation...All 3 techniques allowed a high rate of implant placement; however, the PTFE technique was consistently associated with increased postoperative complications compared with the other 2 methods. The tent screw technique might be more favorable than the tunnel technique in cases in which the bony deficiency is flat.

The modified tent pole technique without the addition of platelet-rich plasma is a safe and effective method to reconstruct the severely resorbed mandible.
