The study will compare initial peri-implant bone healing and longitudinal osseointegration between a fully microtextured dental implant and an analogous implant with a smooth machined collar. The investigators hypothesize the fully textured implant will result in less peri-implant crestal bone resorption than the implant with a machined collar.
Zimmer dental has developed a microtextured tapered screw-vent implant design with a titanium skin that has been grit-blasted with hydroxyapatite particles resulting in an overall roughened surface, which, when compared to an implant with a machined (smooth) collar (narrow band around the top of the device) surface is thought to increase the apposition of osseous tissue integration and to promote epithelial attachment to the implant device.

Microtextured dental implant treatment will include a surgically inserted device implanted into edentulous areas of the jaw where natural teeth have been lost and adequate bone exists.
Treatment with dental implants; implants with a machined collar will be surgically implanted into edentulous areas of the jaw where natural teeth have been lost and adequate bone exists.

Change in Millimeters of Bone Loss Surrounding the Implant Device
Using radiographic images and image-processing software, measurements of bone height at the mesial and distal of each implant will be captured in millimeters.
Time frame: Implant insertion, 12 months post-insertion
Changes in Peri-implant Gingivitis Score
Measurement of changes in peri-implant gingivitis score \[Loe and Silness gingival index (GI)\] after implant restoration
Time frame: 1 year after placement
Millimeters of Periodontal Pocket Depth Surrounding the Dental Implant Device
Probing pocket depth (PD) is measured from the mucosal sulcus to the depth of the pocket attachment after implant restoration.
Time frame: 1 year after placement
