This page presents the data, long-term outcomes, and scientific studies on the success rate of basal implants (BECES/BCS) — an advanced technology in basal implantology.

Long-Term Scientific Evaluation of Basal Dental Implants
Background of the Study on Basal Implants
Basal implantology is based on the use of basal cortical bone — the dense and stable layer of the jawbone (maxilla or mandible) that is not subject to bone resorption.
Unlike conventional implants, which rely on the spongy bone (often weakened in patients with bone loss), BAx (BCS, Strategic Implant®) implants provide immediate mechanical stability.
This allows for rapid functional loading, meaning that fixed prostheses (bridges or crowns) can be placed within just a few days after tooth extraction.
A major scientific study published in 2023 (IOSR Journal of Dental and Medical Sciences) evaluated both the clinical and long-term outcomes of this approach.
Methodology of the Study on BAx Basal Implants
Number of patients: 291
Total implants placed: 2,093 (including 808 BAx basal implants)
Follow-up period: up to 90 months (7.5 years)
Treatment type: Immediate loading (fixed prosthesis within 72 hours)
Patient risk factors: Diabetes, hypertension, smoking — all common risk factors in conventional implantology
The study analyzed several success criteria: implant survival rate, clinical complications (pain, mobility, infection), bone stability, and absence of peri-implantitis.
Clinical and Long-Term Results of Basal Implants
The study demonstrated an exceptional survival rate for BAx (BCS) implants:

- 97.4% after more than 7 years of follow-up
- Results comparable or superior to compressive implants (KOS: 98.5%)
- Older lateral basal implants (BOI) showed much lower results (71.4%), confirming the superiority of the latest BAx generation
Reference Study on Over 2,000 Immediately Loaded Basal Implants
A 2023 scientific publication (Jani et al.) followed 291 patients treated with immediately loaded basal implants, totaling 2,193 monoblock implants (Strategic Implant® BCS) placed according to the protocol of the Implantology Foundation (IF Germany).
Patients were monitored through clinical and radiographic controls over a period of up to 90 months (7.5 years) — making it one of the most comprehensive long-term studies on immediate basal implantology.
The results were remarkable:
- Cumulative survival rate: >99%
- Only 5 implants lost out of 808 BCS implants (0.6%)
No peri-implantitis observed during the entire 7.5-year follow-up period
In comparison, in the same cohort, early-generation disc implants (BOI, n=7) showed a much lower survival rate (~71%), highlighting the technological advances made with the new BAx screw-type basal implants.
Another key finding of the study is the complete absence of peri-implantitis around the observed basal implants.
No destructive bone inflammation was recorded over 7.5 years of follow-up, confirming the resistance of basal implants to peri-implantitis.
This is attributed to their polished surface and the dense cortical bone anchorage, which is less susceptible to bacterial colonization.
Additionally, 97.8% of implants were functional at placement (immediate success rate) and 99.5% after prosthetic adjustments.
In other words, nearly all implants were placed in satisfactory function from the beginning.
Over the long term, the cumulative survival rate remained above 99%, and clinical success (defined as absence of pain, infection, mobility, or bone loss) was observed in 97–98% of implants.
These results demonstrate the exceptional reliability and long-term success of basal implants.

Basal Implants Success Rate Over Time (Postoperative Follow-Up Data)
| Suivi post opératoire | Taux de survie |
| 3 months | 100 % |
| 6 months | 100 % |
| 12 months (1 year) | 99,9 % |
| 24 months (2 years) | 99,5 % |
| 60 months (5 years) | 99,2 % |
| 90 months (7.5 years) | 99,2 % |
Conclusion: Clinical Outcomes of Basal Implants (BAx / BCS)
Between 3 months and 1 year, the success rate remained practically 100%.
Only 1 implant out of 800 failed in the first year (99.9% success).
A few rare failures occurred between years 1 and 2, bringing the survival rate to ~99.5%.
Beyond 2 years and up to 7.5 years, no further implant failures were recorded, stabilizing the long-term survival rate at ~99.2%.
These exceptionally high results are consistent with other studies on basal implantology.
For instance, a 2021 publication (Patel et al.) reported a cumulative survival rate of 97.5% at 18 months for 157 immediately loaded basal implants, with no peri-implantitis cases during follow-up.Similarly, international literature reports 97–99% success rates over 5 years for immediately loaded basal implant protocols.
These results align with those of Jani et al. (2023), confirming that modern basal implants offer success rates equal to or better than conventional implants, even in more complex cases.
This reinforces the position of this technology as a reliable long-term solution in advanced implantology.
