Placement of a Zimmer Trabecular Metal Dental Implant with Simultaneous Ridge Augmentation and Immediate Non-Functional Loading Following Tooth Extraction and Orthodontic Treatment for Implant Site Development Case # 1 Author: (USA)
Pre-operative buccal view shows a missing maxillary right lateral incisor provisionally restored with a composite pontic veneer during adult orthodontic treatment for implant site development.
Pre-operative periapical radiograph shows the healed extraction site with the provisional composite pontic veneer in place supported by orthodontic wire.
Buccal view of the edentulous site after removing the provisional composite pontic veneer and orthodontic wire.
The edentulous ridge is surgically exposed and an osteotomy is sequentially prepared using internally irrigated drills in graduated diameters and copious external irrigation. During the procedure, a depth gauge is placed into the osteotomy to ensure parallelism with the adjacent dentition and to measure the depth of drill penetration.
Further flap reflection after preparation of the osteotomy reveals an undercut in the alveolar process.
A Zimmer Trabecular Metal Dental Implant, 4.1 mm x 13 mm, is threaded into the osteotomy utilizing its fixture mount with a hex instrument and surgical screwdriver handle.
Buccal view shows the Zimmer Trabecular Metal Dental Implant fully seated in the osteotomy. Note that the fixture mount has achieved parallelism with the adjacent teeth.
The fixture mount is removed from the implant and prepared for use as a provisional abutment. Note the implant s lead-in bevel and internal hex connection.
Puros Cortico-Cancellous Particulate Allograft is hydrated prior to use.
The prepared fixture mount is attached to the implant and its screw access hole is occluded with composite material. Puros Cortico-Cancellous Particulate Allograft is placed in the ridge defect and covered with a barrier membrane.
A composite crown is provisionally cemented onto the temporary abutment. The soft tissues are mobilized for tension-free closure and sutured around the provisional restoration.

Immediate Placement and Functional Loading of a Zimmer Trabecular Metal Dental Implant in the Maxillary Esthetic Zone Case # 2 Author:
Pre-operative buccal view shows a fractured maxillary right central incisor.
Pre-operative periapical radiograph shows the intact root of the fractured maxillary right central incisor.
The root tip is gently split and removed in segments to preserve the surrounding bony architecture. Prior to osteotomy preparation, the socket is debrided to remove remaining root fragments and any remaining granulation tissue.
The socket is sequentially formed and enlarged to receive the implant using internally irrigated drills in graduated diameters and copious external irrigation.
The Zimmer Trabecular Metal Dental Implant is delivered to the osteotomy using its fixture mount.
The Zimmer Trabecular Metal Dental Implant is placed using a hex instrument in a reduction contra-angle at slow speed.

Circumferential voids around the top of the implant are augmented with hydrated Puros Cancellous Particulate Allograft. The soft tissues are mobilized and approximated for tension-free suturing.
Immediate temporary restoration at the time of implant placement.
Provisional restoration two weeks post implant placement.
Post-operative periapical radiograph shows the provisional restoration in place.
Final restoration ten weeks post implant placement and one week following final crown delivery.

Sinus Augmentation with Puros Cortico-Cancellous Particulate Allograft Mix and Immediate Placement of a Zimmer Trabecular Metal Dental Implant into a Fresh Extraction Socket Case # 3 Author:
Pre-operative occlusal view shows a fractured maxillary left 1 st molar.
Pre-operative periapical radiograph shows pneumatization of the sinus with a vertically resorbed residual ridge.
After tooth extraction, the facial plate is surgically exposed for subantral augmentation utilizing a lateral approach.
Access through the lateral sinus wall is performed utilizing the Sinus Lateral Approach (SLA) reaming instrument in a slow-speed handpiece.
After careful penetration through the lateral wall of the sinus, the reaming instrument is removed with the intact facial plate bone core.
Buccal view of the surgical site shows the Schneiderian membrane intact.
An elevator is used to carefully remove the Schneiderian membrane from the sinus floor for elevation prior to graft placement.
After mobilization of the Schneiderian membrane, the extraction socket is formed and enlarged to receive the implant by sequential cutting with internally irrigated drills and under copious external irrigation.
A CollaTape Wound Dressing was used to isolate the membrane and allow the placement of the graft material. 2013 2012 Zimmer Dental, Inc. All rights reserved. 6557, Rev. 03/13. 10/12.
