Six split-mouth cases. Real-world ISQ values.
To increase the reliability of the data, a split-mouth design was used — the same patient, same drilling sequence, same bone graft material on both sides. The only variable: 10 seconds inside SQUVA.
How the data was collected
One dentist performed every step — surgical placement, ISQ measurement, prosthesis installation. Same SQ implant surgical kit, same drilling sequence, same bone graft material on left vs. right and anterior vs. posterior of the same patient. Yellow markers indicate untreated implants; blue indicate SQUVA-treated implants.
SQ implant placement on healed ridge
Bilateral healed ridge with nearly identical bone density. Both #36 and #46 placed; SQUVA only on #36. ISQ measured at op-day, 6 and 12 weeks.
The implant treated with SQUVA showed an approximately 15% larger ISQ rise in the first six weeks than the untreated implant.
Comparison of implants with vs. without SQUVA
Incompletely healed ridge, ipsilateral anterior & posterior. Both implants inserted at 30 N torque.
The SQUVA-treated implant showed a 30% greater rise in ISQ value by three months than the untreated control.
Immediate placement after extraction
Bilateral extraction of maxillary anterior teeth with small GBR; SQ implants compared on three sites.
A modest 5–8% larger ISQ rise for SQUVA-treated implants. The high baseline bone density of the maxillary anterior region naturally limits the effect that any surface treatment can show.
Sinus grafting with simultaneous placement
Lateral approach. Same drilling, same bone graft, anterior & posterior of the same maxillary sinus. Despite a much shorter residual bone height (2–3 mm) on the SQUVA side vs. 4–5 mm on the control side…
…the SQUVA-treated implant achieved a 30% greater ISQ rise at five months than the untreated implant — even though the SQUVA side started with worse bone.
Sinus grafting with simultaneous placement by SQUVA
Residual bone height of just 1–2 mm. Progressive loading at 5 months until ISQ stabilised, then final prosthesis at 7 months.
Both implants gained ISQ steadily — but the SQUVA-treated implant climbed faster and finished higher across the entire timeline.
Delayed placement on sinus-grafted area
Failed implant and fungal-infected area removed. Sinus bone grafted, six-month wait, then placement on both sides — two SQUVA, two untreated.
Where the host bone has been formed long before the implant goes in, the SQUVA effect is smaller — but still consistently positive on every quadrant.
ISQ rise — SQUVA vs. control
Across six cases, every single SQUVA-treated implant showed equal or higher ISQ improvement than its split-mouth control.
All values from SQUVA Clinical Report Vol. 1. Bars show the highest ISQ value recorded for each implant.

Seoul H Dental Clinic. Author of SQUVA Clinical Report Vol. 1, May 2022 (D-C-CRSQV-V1-202205-KOR). Dr. Jeon performed every surgical procedure and prosthesis installation in the report personally, and applied a strict split-mouth methodology so that every observed ISQ difference is attributable to the SQUVA cycle rather than to confounding patient factors.
