Pre-operative situation showing the horizontal ridge deficiency (left). Buccal bone concavity evident after full thickness flap elevation (middle). There is insufficient bone to place implants in an ideal restorative position (right).

It is important to locate the mental foramen. Intramarrow penetrations were done to allow for improved blood supply to the bone graft.

The clinical cocktail used for guided bone regeneration: 1) 50/50 mixture of autogenous bone chips, collected with Geistlich SafeScraper TWIST, and Geistlich Bio-Oss®, and 2) Geistlich Bio-Gide® Compressed 20 x 30 mm and 13 x 25 mm.

“Sticky bone”, created by combining PRF with the bone graft, adapted well to the site of the defect. Periosteal biting sutures were used for stabilization of the multiple layers of Geistlich Bio-Gide® Compressed and underlying bone graft.

Geistlich Bio-Gide® Compressed was carefully trimmed to be mindful of the mental nerve.

Tension-free primary closure achieved with horizontal mattress sutures and simple interrupted sutures.

Re-entry and CBCT scan at 8 months showing a significant increase in horizonal bone dimension.

Sufficient regenerated bone to allow for implant therapy (left). Implants #19 and #20 placed. Vital bone from guided bone regeneration as evidenced by the bleeding bone (middle). Tension-free primary closure achieved using 5-0 glycolon sutures.

Left: Tooth #9 was extracted with minimal flap elevation, preserving the papillae. Right: A 3.6 x 15 mm implant was placed in a fully guided manner with a palatal bias to maximize the facial gap dimension, achieving a +2mm gap.

Left: The underside of the periosteum was incised just apical to the mucogingival junction, and a supra-periosteal pocket was created using sharp dissection with a #15 blade. Right: The facial gap was packed with 50 mg of Geistlich Bio-Oss Collagen®. A cover screw was temporarily placed to prevent bone graft granules from entering the implant chamber.

Left: A 15mm x 20mm x 3mm Geistlich Fibro-Gide® collagen matrix was inserted into the supra-periosteal pocket, with the coronal portion positioned to cover the facial bone crest. Right: The provisional crown was placed, and the facial mucosal flap was coronally advanced to cover the Geistlich Fibro-Gide® collagen matrix.

Initial Situation: a failing mandibular molar with a vertical sub-osseous fracture.

A pre-operative radiograph and CBCT showing the cross-section of the involved tooth.

An implant site was developed by placing a pilot drill down the mesial root space, then uprighting it. This was continued up through the drill sequence. The mesial radicular septum is moved in the process.

A Camlog® 5.0 x 11 mm implant was placed with the platform set just down below the bone height of the socket walls.

After placing a 4.0 mm height cylindrical gingiva former in the implant, 250 mg of Geistlich Bio-Oss Collagen® was packed down in the socket around the implant.

Geistlich Mucograft® was adapted to the region then tucked down under the gingival margin.

The gingival margins were adapted and closed together with 4.0 teflon sutures (Cytoplast™, Osteogenics). The region was then covered with Glustich - PeriAcryl®90 Oral Tissue Adhesive.

After 3 months of healing, the top of the gingiva former is exposed and the situation is ready for Emergence Profile Development. This is quite standard.

Clinical presentation of tooth #31 showing radiographic evidence of bone loss, profuse bleeding on probing (BOP), deep probing depths, and suppuration, indicative of peri-implantitis with a Class I-infraosseous (c) circumferential-type defect, as described in the study by Monje et al. (2019) Clin Implant Relat Res, 21(4)635-643.

Crown removal by the prosthodontist, followed by placement of a healing abutment for non-surgical therapy using PerioFlow®. After therapy, a cover screw was placed, and the tissue was allowed to heal over the implant for eight weeks.

Surgical treatment initiated with a midcrestal incision and full-thickness flap elevation. Granulation tissue was removed using a surgical curette, revealing a deep infrabony defect.

Implant thoroughly decontaminated using Perioflow® with erythritol powder to ensure a clean surface for regeneration.

rhPDGF-BB was used to hydrate bone grafting materials (vallos® Demineralized Cortical Granules and Geistlich Bio-Oss®), which were first hydrated with sterile water before rhPDGF-BB was added. The materials were mixed in a 1:1 ratio and allowed to sit for 10 minutes before being applied to the deep infrabony defect to promote regeneration.

Flap closed primarily with 5-0 PTFE horizontal mattress and single interrupted suture for secure closure.

Collagen membrane stabilized with 5-0 chromic gut sutures using the lasso technique.

After 5 months of healing, significant bone gain is evident. Geistlich Bio-Oss® was placed on the buccal site to enhance thickness, covered with an amnion-chorion membrane. A healing abutment was placed at this stage.

Two-year follow-up shows disease resolution with shallow probing depths, no bleeding or suppuration, and complete bone gain. A new crown was fabricated with an increased final abutment height (>2mm), contributing to optimal maintenance and long-term stability based on evidence supporting its role in promoting long-term success. A second surgery may be necessary to gain additional tissue thickness or cover residual thread exposure to achieve the desired long-term results.

Baseline full-mouth intra-oral view: the residual maxillary teeth were preliminarily reconstructed with a composite mock-up. The horizontal atrophy of the posterior areas of the maxilla is clearly visible.

The cone beam, realized with a radio-opaque diagnostic template, shows inadequate bone volume for implant placement in all the analyzed sites.

The use of the diagnostic template during the augmentation procedure helps to highlight the presence of bone defects in relationship to the restorative plan and future position of implants.

Large Geistlich Bio-Oss® particles are directly applied inside the sinus with Geistlich Bio-Oss Pen®.

The Geistlich Bio-Gide®, fixed with titanium pins is used to protect and stabilize the augmented site. As the surgical template shows, the bone augmentation is based on the future restorative project following the principle of PGR.

The same surgical procedure is performed on the left posterior side of the maxilla.

Cone-beam 6 months after surgery and prior to implant placement. The relationship between the template used for diagnosis and the bone crest reveals adequate bone volume to place implants in the correct prosthetically driven position.

Implant placement was guided by the same template utilized for diagnosis and bone augmentation.

Final view of the prosthetic reconstruction demonstrates bio-mimetic integration of implant-supported prostheses and ceramic veneers bonded to residual natural teeth.

The panoramic radiograph shows adequate integration of the implants and absence of peri-implant bone resorption.
