About

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.

Full description

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).

Inclusion criteria

Adult patients requiring dental implant reconstruction who would undergo implant surgery with or without participation in the study.
The patient must need at least four implants placed in one or both jaws of the maxilla or mandible.
All patients must undergo informed consent and willingly read, understand, and accept the risks and benefits associated with the study.
Willingness to participate for the duration of the study of at least six months follow-up
Is healthy enough to undergo implant surgery. i.e. patient is classified by the American Society of Anesthesiology Scale (ASA) physical status classification status as ASA 1, 2 or 3.
