Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to compare the clinical outcome of Navigated Photogrammetry to standard stereophotogrammetry techniques in digital dentistry for the following two parameters:

* The amount of time needed to prepare the provisional digital files for use in the lab, measured in direct doctor interaction time.
* Suitability of delivered provisional occlusion.

Participants will receive either a provisional manufactured by the output of Navigated Photogrammetry, or a provisional manufactured by the output of standard stereophotogrammetry.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Prior to implant surgery, a patient treatment plan is developed using a cone-beam computed tomography (CBCT), Intra Oral Scan (IOS), or digitized analog records. These records are loaded into a computer-aided design (CAD) program. The individual planning files are all related to one another in one coordinate system. This plan can be used to produce provisional restorations via computer-aided manufacturing (CAM). These files can also be used to implement the plan during surgery using either static guides or dynamic navigation.

Following implant surgery, the final placed implant locations will inherently have some deviation from the plan. It is important for the dentist to understand the physical location of the placed implants to achieve passive fit. In implant dentistry, a "passive fit" refers to the precise alignment and seating of prosthetic components onto dental implants without any internal stress or strain. Achieving a passive fit is crucial for the long-term success and stability of the dental prosthesis.

A potential method to obtain the final implant locations is stereophotogrammetry. Navigated Photogrammetry (NPG) is a new form of stereophotogrammetry which is inherently capable of relating the placed implants to the patient's anatomy using the registration of the Dynamic Surgical Navigation System (DSNS).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

FastMap Navigated Photogrammetry

Following implant surgery, the patient will then receive a provisional that was manufactured using the data from FastMap Navigated Photogrammetry.

Navigated Photogrammetry

Intervention Type DEVICE

Navigated Photogrammetry shall be performed following implant surgery, rather than standard stereophotogrammetry. The patient will then receive a provisional that was manufactured using the data from FastMap Navigated Photogrammetry.

Standard Stereophotogrammetry

Following implant surgery, the patient will then receive a provisional that was manufactured using the data from Standard Stereophotogrammetry.

Standard Photogrammetry

Intervention Type DEVICE

The patient will receive the existing patient care protocol that includes anatomy information for the manufacturing of the provisional. Specifically, the patient will receive a preoperative IntraOral Scan (IOS) anatomy scan with IOS-compatible fiducials. Following implant surgery, the patient will receive a scan with a standard stereophotogrammetry device. Additionally, they will receive a post-op alignment IOS with IOS-compatible anatomy fiducials and IOS-compatible implant scan bodies. The patient will then receive a provisional that was manufactured using the data from the standard stereophotogrammetry device.
