Osstem Implant
Osstem CA Dental Implant
This fixture adds a calcium (Ca) ion coating to the SA surface treatment to accelerate chemical bonding with bone cells. It provides excellent primary stability and achieves faster osseointegration than conventional SA.
What is Osstem CA?
Osstem CA (Calcium-coated Acid-etched) is an implant fixture in which the existing SA (Sandblasted & Acid-etched) surface is additionally coated with a calcium (Ca) ion solution to create an additional coating. Calcium ions bone-forming cells (osteoblasts)promote their activity, leading to faster and more stable early osseointegration than SA.
CA surface treatment Key technology
SA’s physical roughness + calcium’s chemical bonding strength
Calcium ion coating
A calcium (Ca) ion solution is additionally applied to the SA surface. Calcium is a key component of hydroxyapatite (HA), the main constituent of bone, and is highly biocompatible.
Osteoblast activation
Calcium ions promote osteoblast attachment and proliferation on the implant surface. This accelerates new bone formation and improves early stability.
SLA-based rough surface
A micro-rough surface created by dual sandblasting and acid-etching provides an environment where bone cells adhere well.
Proven safety
Osstem, Korea’s first implant developer, has 30+ years of clinical data and exports to 70+ countries worldwide.
Faster osseointegration
Compared with the 6~8 weeks typical for SA, the osseointegration period is shortened to 4~6 weeks. Earlier prosthesis placement becomes possible, reducing overall treatment time.
Affordable pricing
Delivers premium-level performance at a reasonable price. A high-value choice with excellent results for the cost.
Osstem CA vs SA Comparison
CA is an upgraded version of SA.
| Comparison criteria | SA (basic) | CA (calcium coating) |
|---|---|---|
| Surface treatment | Sandblast + Acid-etch | SA + calcium (Ca) ion coating |
| Osseointegration period | 6~8 weeks | 4~6 weeks |
| Initial stability | Excellent | Outstanding |
| Biocompatibility | Physical bonding | Physical + chemical bonding |
| Ideal candidates | General patients with good bone quality | Patients concerned about delayed healing (smokers, diabetes, etc.) |
| Pricing | Entry-level | Reasonably priced (Standard) |
For these patients, we recommendthis
Cases where Osstem CA is particularly suitable
Those with good bone quality
Those who have sufficient jawbone but want faster osseointegration than the basic type
Smokers
Those whose osseointegration may be delayed due to smoking. The calcium coating helps enhance initial stability.
Patients with diabetes
Those concerned about delayed healing due to diabetes. Faster osseointegration may reduce the risk of infection.
Prioritize performance for the cost
Provides top value for those who want premium-level performance at a reasonable price.
Want to finish treatment quickly
Osseointegration 2~4 weeks faster than SA may shorten the time to place the final restoration.
Single or few implants
Ideal for patients who want to place about 1~3 routine implants reliably.
Frequently Asked Questions
Questions about Osstem CA
CA is a product with calcium ions coated onto the SA surface, while BA is a premium option that combines the benefits of SA and HA (hydroxyapatite) coatings. BA is a step above CA and can be applied more broadly across various bone qualities.
With proper oral care and regular checkups, it can last more than 20 years. Osstem provides a 10-year warranty, and in real-world clinical use, lifespans often far exceed this.
If bone is weak, we recommend higher-tier options such as SOI or BA. CA is suitable for patients with good or slightly deficient bone quality. We’ll give a precise recommendation after a CT scan and consultation.
The overall success rate of Osstem Dental Implants has been reported at over 97%, and thanks to the calcium coating that enhances initial stability, CA can be expected to perform even better.
