How to Improve Implant Scan Accuracy With Intraoral Scanners

Implant accuracy begins before scanning

An implant scan requires more control than a routine digital impression with a scan body added at the end. The scan body creates the reference geometry that connects the implant's clinical position to the digital model. A loose, contaminated, incorrectly selected, or incompletely captured component can lead to an incorrect rotational or positional relationship in the design.

The scanner works best when the component is fully seated and the field is stable. A reliable protocol has four parts: confirm the components, control the clinical field, capture identifiable geometry in a repeatable sequence, and verify the file before design begins.

Prepare the scan bodies and the field

Confirm the component before capture

Check the scan-body type against the implant system and planned restoration. Follow the component manufacturer's instructions for seating and tightening. Inspect the interface for debris and confirm that the body is stable. In a multiple-implant case, record the component count so the reviewer can confirm that every planned position appears in the digital file.

Resolve seating uncertainty clinically before relying on the digital model. Even a technically complete scan represents the wrong implant position when the component is not clinically correct.

Control moisture and movable tissue

Saliva, blood, and condensation can obscure scan-body edges or create glare on reflective surfaces. The tongue, cheek, and mobile mucosa may also change between frames and become unstable registration information. Use retraction and suction appropriate to the case, dry the surfaces that must be captured, and keep mobile tissue out of the critical reference area whenever possible.

The practical goal is to keep the scan body, neighboring reference anatomy, and bite surfaces readable while those areas are being captured, rather than to dry every part of the mouth for the entire appointment.

Choose the sequence for the anatomy

Single implant beside natural teeth

Natural teeth provide distinctive cusps, grooves, proximal surfaces, and incisal edges. Start in an area with stable anatomy, then move toward the scan body while maintaining enough neighboring reference data for registration. Capture the upper geometry and the transition to adjacent anatomy clearly. Inspect the scan body before leaving the area.

Multiple implants

Treat several scan bodies as individual reference components rather than one smooth, continuous field. Capture each body's identifying geometry and inspect the transitions between bodies. Keep stable anatomy or a deliberately planned reference area visible as the scan progresses. When one section is uncertain, rescan it before moving to a distant implant.

Edentulous or low-texture arches

An edentulous ridge offers fewer fixed landmarks than a dentate arch. Long passes across smooth tissue can increase the chance of tracking drift. Use shorter segments, slower controlled movement, and more frequent local checks. When tracking is lost, return to the last reliable region and reconnect the data from a confirmed reference area.

How the BSM M5 Pro fits the implant workflow

The BSM M5 Pro intraoral scanner is described by Besmile as a scanner for accurate and stable digital impressions in daily clinical workflows. Its official product introduction identifies aerospace-grade low-expansion materials around the optical module, a high-resolution projection chip, efficient data transmission, aluminum alloy housing, an FDA-certified medical-grade tip, one-touch motion control, and plug-and-play connectivity.

For implant cases, these features support a consistent capture rhythm through complex areas. Responsive equipment can make it easier for the operator to pause, reorient, and rescan a local region without adding unnecessary handling steps. Component verification and clinical judgment remain essential.

Besmile lists the M5 Pro at 222 x 33 x 28 mm and 167 g including the tip and excluding the wire. The listed scan field is 18 x 16 mm and the depth of field is 0-20 mm. The published device data includes six autoclavable tips, STL, PLY, PTY, and OBJ output formats, accuracy of <=8 micrometers, and precision of <=6 micrometers.

These are manufacturer-published device specifications for equipment evaluation. Implant-level and prosthetic fit also depend on scan-body seating, patient movement, moisture, operator technique, software processing, and verification.

Verify the scan before sending the case

Inspect each scan body

Confirm that every planned scan body is present, its boundary is complete, and its upper geometry is readable. Review the top surface together with the sides and transitions. The digital model needs enough geometry to establish the component's rotational and vertical relationship. A missing side or transition calls for local recapture before design.

Compare the model with the mouth

Review the digital tissue, neighboring teeth, implant positions, and any distinctive anatomy against the clinical situation. Look for an implausible arch shape, local duplication, a gap around a scan body, or a transition that does not align with the surrounding anatomy. In an edentulous case, pay particular attention to long spans where small drift may be difficult to notice by color alone.

Check the opposing arch and bite

A correct implant scan still needs a credible opposing scan and bite relationship. Confirm that the bite data contains stable anatomy and that the digital relationship is clinically plausible. Treat bite verification as a separate acceptance step rather than assuming that a complete arch automatically means a complete occlusal record.

Recover tracking without spreading the error

When tracking begins to drift, stop and identify the last region that is clearly correct. Keep that area visible, reduce the movement speed, and recapture forward in a shorter segment. If the problem is caused by reflection, saliva, or tissue movement, change the condition before repeating the scan.

After a recovery, inspect the join between the original and new data. A complete-looking color model can still contain a positional discontinuity. If a local repeat scan does not align consistently with the original, remove the questionable section and capture it again while stable reference anatomy remains available.

Define the clinic-laboratory handoff

The clinic is responsible for component selection, seating, tissue management, and capture quality. The laboratory is responsible for file completeness, suspicious geometry, and requesting clarification before manufacturing. A shared record can include scan-body type, implant count, seating confirmation, opposing scan, bite scan, soft-tissue limitations, and areas that were rescanned.

This division prevents both sides from assuming that the other has completed the critical review.

Match review effort to case risk

A single implant next to stable teeth may need fewer review steps than a full-arch edentulous case. Multiple implants, reflective components, limited opening, mobile tissue, and long low-texture spans each increase the need for local verification. The team should define when a second operator, laboratory review, or additional verification method is required.

Reserve deeper review for cases where the consequence of an unnoticed positional error is high. A risk-based protocol protects complex implant work while keeping routine cases efficient.

Source and clinical scope

The M5 Pro specifications are taken from the official Besmile product page. They provide equipment reference data and should be combined with case-specific validation, relevant component instructions, and professional clinical judgment.

Conclusion

Reliable implant scan accuracy comes from correct scan-body selection and seating, controlled moisture and tissue, a sequence suited to the anatomy, complete bite data, and independent verification. The BSM M5 Pro provides published optical, handling, and output specifications for evaluating the scanning stage. At Besmile, we present those official product details so clinics and laboratories can assess the equipment while validating their own implant scanning protocol.
