They do different jobs. Dental photogrammetry records the positions of multiple implants—particularly useful for full-arch cases—while a laboratory scanner digitizes a physical cast, impression, or model for lab work. A lab scanner can help measure a model in a study, but that does not make it a substitute for capturing implant positions in the patient. In some workflows, both technologies are used.
What each technology captures
| Technology | Primary role in an implant workflow | What the comparison does—and does not—mean |
|---|---|---|
| Dental photogrammetry | Registers the spatial positions of implant-mounted markers, often across an edentulous full arch. | It captures implant-coordinate information. Accuracy depends on the system, components, geometry, and measurement method. |
| Laboratory scanner | Digitizes a physical object such as a cast, impression, or model for laboratory design and production. | It scans the object presented to it; it does not, by itself, directly record implant positions in a patient’s mouth. |
| Intraoral scanner (IOS) | Captures oral surfaces and scan components directly in the mouth. | It is a different capture approach from both model digitization and photogrammetry, and is often the comparator in full-arch accuracy studies. |
These roles can meet in one case: a clinician or lab may capture implant positions with photogrammetry, then combine that information with a scan of soft tissue or a model in the design workflow. The exact steps and file handling depend on the system and laboratory software. A desktop scanner may also digitize a model to create a reference dataset in an accuracy study, rather than serve as the clinical implant-position capture method. For examples of this distinction, see the methods used in the 2024 six-implant model study and the 2025 four-implant model study.

Is photogrammetry more accurate for full-arch implants?
Published comparisons often favor photogrammetry over conventional intraoral scanning for registering implant positions across a complete arch, but the evidence does not establish a universal winner for every patient, system, or prosthesis. The results depend on the arch and implant geometry, scan bodies or markers, tested equipment, reference instrument, and the accuracy measure used.

The review found substantial differences among study methods and concluded that intraoral scanning and photogrammetry showed comparable accuracy for registering implant positions. It also called for clinical work to establish what level of prosthesis misfit is tolerable.

A 2025 systematic review and meta-analysis included 13 studies: three in vivo and ten in vitro. Stereophotogrammetry showed higher accuracy than intraoral scanning in 10 of the 13 studies, with exceptions and variation across study conditions and measures. The authors called for more clinical trials. That result summarizes the included studies; it does not prove that every photogrammetry system will outperform every IOS in a clinical case.
Individual experiments answer narrower questions. In a 2025 in vitro study using a four-implant edentulous mandibular model, the tested Aoralscan Elite IPG configuration performed better across the measured accuracy parameters than the three directly scanned IOS configurations. The authors described the finding as preliminary and said clinical studies are needed. A 2024 in vitro comparison used a six-implant edentulous maxillary model to compare conventional impressions, standard and splinted intraoral scans, and stereophotogrammetry, with an industrial blue-light scanner as its baseline. Neither model study establishes how all systems will perform for different patients or clinical conditions.

Why a lab scanner’s micron specification is not a clinical fit result
A scanner specification and an implant-impression accuracy result are not automatically comparable. A published device specification describes performance under the manufacturer’s stated test method; a study may instead compare implant-position deviation against a reference dataset. Neither number alone tells you whether a finished prosthesis will fit acceptably in a particular patient.
For example, 3Shape’s Lab Solutions page lists the E4 at a manufacturer-stated accuracy of 4 μm under ISO 12836 and a full-arch scan speed of 9 seconds. These are product specifications, not independent evidence that an implant prosthesis made from a scan will achieve a corresponding clinical fit. Confirm the current model specifications and availability for your region with the manufacturer or distributor.

How to choose a workflow for an implant case
Choose the capture method around the case and the receiving lab’s process, rather than selecting equipment by a single headline accuracy figure.
- Define what must be captured. If the key need is to register the relative positions of several implants—especially across an edentulous full arch—photogrammetry is designed for that role. If the lab needs a digital version of a physical cast, impression, or model, a laboratory scanner serves that purpose.
- Match the evidence to the case. Check whether the published comparison used a similar arch, number and distribution of implants, capture system, markers, and accuracy metric. Give in vitro findings less weight as predictions of clinical performance than direct clinical evidence.
- Verify component compatibility. Confirm that the markers or scan components are supported by the chosen capture system and match the specific implant platform. A marker library or supported-device list is system-specific; for example, PIC Dental’s PIC app page describes its marker library and supported iPhone models. Check current compatibility with the manufacturer before planning a case.
- Confirm the lab handoff. Ask the lab which files, scans, and supporting records it needs, and whether its software and CAD/CAM process can use the proposed capture output. Account for file transfer and any additional model or soft-tissue scan required.
- Check practical support. For equipment under consideration, confirm current regional availability, training, service, physical setup, and the exact capture steps with the vendor. These operational details can affect whether a technically suitable workflow is workable for the practice and lab.
Where the technologies fit together
Photogrammetry and laboratory scanning are best understood as complementary tools at different stages, not competing versions of the same scanner. Photogrammetry can supply implant-position data; a lab scanner can digitize a cast or model used in the same laboratory workflow. Whether both are needed depends on the case, the records the lab requires, and compatible equipment and software. A dedicated system such as the one described on PIC Dental’s product page is a commercial example of dental photogrammetry, not independent evidence of superiority over other systems.
