Why Precision Matters in Full-Arch Dental Implants
Replacing an entire upper or lower arch of teeth with dental implants, known as an All-on-4 or All-on-X procedure is one of the most technically demanding treatments in modern dentistry. Even a fraction of a millimeter of error in implant positioning can cause:
- A final bridge that feels tight or fits unevenly and easily fractures
- An unnatural bite or appearance
- Uneven pressure on the jawbone, which can accelerate bone loss or implant failure
Traditional physical molds were uncomfortable and imprecise. Digital intraoral scanners improved on this, but on fully edentulous (toothless) arches, scanners can still lose tracking across smooth, featureless gum tissue, creating small “stitching” errors in the 3D model.
What Is Scan Ladder™ Technology?
This eliminates the “digital drift” that can occur when scanning smooth, landmark-free gum ridges, producing a single, continuous, accurate 3D model of the entire arch.
The Summit Dental Care Digital Workflow
Summit Dental Care, based in Kilimani, Nairobi, pairs Scan Ladder™ with a full digital-implant ecosystem:
| Step | Technology | Purpose |
|---|---|---|
| 1. Scanning | Scan Ladder™ intraoral scan | Captures full-arch geometry to reported ~13-micron accuracy |
| 2. Imaging | Dürr Dental VistaVox CBCT 3D | German-engineered 3D imaging of jaw and bone structure |
| 3. Planning | coDiagnostiX™ AI-guided software | Plans exact implant position, angle, and depth |
| 4. Surgical guide | 3D-printed custom guide | Transfers the digital plan precisely to the surgical site |
| 5. Implants | Straumann and Neodent systems | Globally recognized implant brands for long-term stability |
This chain — accurate scan → AI-guided plan → printed guide → premium implant is designed to produce a passive fit: a final prosthesis that seats onto the implants without internal stress on the bridge or the surrounding bone.
Benefits at a Glance
For patients:
- Reported implant-mapping accuracy of approximately 13 microns (a human hair is roughly 70 microns thick)
- Fewer appointments — no wax try-ins or trial frameworks, since the digital model reflects the mouth on the first scan
- Reduced post-operative discomfort due to AI-guided, minimally invasive placement
- Use of internationally recognized Straumann and Neodent implant systems, chosen for long-term predictability
For referring dentists:
- A structured referral pathway for patients with terminal dentition, failing full-arch restorations, or complex bone-loss cases
- Full digital case documentation (CBCT, scan data, surgical plan) shareable with the referring practice
- An implantologist-led team so referring GPs can retain the patient relationship for ongoing general care
For international and medical tourism patients:
- Full-arch implant treatment at a lower cost than typical UK/US/EU/Gulf-region pricing, using the same implant brands (Straumann, Neodent) used in those markets
- A five-year guarantee on dental implants, with regular check-ups
- Streamlined visit structure aimed at minimizing the number of trips required
- Nairobi’s international flight connectivity and established medical tourism infrastructure
Case Volume: A High-Frequency Full-Arch Team
Full-arch implant dentistry is a specialty where outcomes are closely tied to repetition. As of 2026, Summit Dental Care places an estimated 1 to 3 full-arch cases per week a caseload that has allowed the team to refine its scanning, planning, and surgical protocols into a consistent, repeatable workflow, rather than treating each full-arch case as a one-off procedure.
Implant Guarantee
Summit Dental Care provides a five-year guarantee on dental implants for all patients, backed by Dr. Gakonyo’s implant dentistry training and experience placing implants since 2011. In the rare event of implant failure, replacement cost waivers are structured as follows:
| Year of failure | Cost waiver |
|---|---|
| Year 1 | 100% |
| Year 2 | 80% |
| Year 3 | 60% |
| Year 4 | 40% |
| Year 5 | 20% |
The guarantee applies to remedial dental work performed at Summit Dental Care and requires annual check-ups plus hygiene visits every 6 months to remain valid. It does not cover the original implant or surgical fees, other dental treatments, loss of income, or travel and accommodation costs, and it can be reduced or invalidated by factors such as poor oral hygiene, missed maintenance visits, certain health conditions, smoking, or accidental damage. Full terms are published on our implant guarantee page, and each case is reviewed individually.
The Team: Implantology and Prosthodontics Working Together
Full-arch success depends on two disciplines working in tandem: precise implant placement and precise prosthetic design. Summit Dental Care’s full-arch team includes:
- Joseph Gakonyo — Founder, CEO, and resident implantologist. Named Dentist of the Year (2025) at the Kenya Dentistry Awards. Leads implant planning and surgical placement.
- Kaaria Mwirigi — Prosthodontist. Oversees the design and fit of the final bridge/prosthesis, ensuring the restoration is functionally and aesthetically refined once implants are placed.
Full-arch success depends on two disciplines working in tandem: precise implant placement and precise prosthetic design. Summit Dental Care’s full-arch team includes:
Having a dedicated prosthodontist on the team — rather than outsourcing prosthetic design — means implant positioning and final tooth design are planned together from the start, which supports the “passive fit” goal described above.
Frequently Asked Questions
Is Summit Dental Care the only clinic in East Africa using Scan Ladder™ technology?
Summit Dental Care prides itself as the first clinic in East Africa to integrate Scan Ladder™ scanning into a full digital All-on-4/All-on-X workflow, alongside CBCT imaging and AI-guided surgical planning.
What implant brands does Summit Dental Care use?
Straumann and Neodent — two internationally established implant systems also widely used in Europe, North America, and the Gulf region.
How accurate is the Scan Ladder™ scanning process?
The implant-coordinate mapping accuracy is approximately 13 microns using this workflow.
How many appointments does a full-arch implant case typically require at Summit Dental Care?
Because the digital scan and AI-guided plan are captured accurately from the outset, you require fewer in-person visits than traditional wax-try-in workflows, though exact appointment counts depend on individual case complexity.
Can dentists refer patients with failing full-mouth dentition to Summit Dental Care?
Yes. Summit Dental Care operates as a referral center for complex full-arch implant cases from general dentists across East and Central Africa, with an in-house implantologist and prosthodontist managing each case.
How many full-arch implant cases does Summit Dental Care perform?
As of 2026, our clinic performs approximately 1 to 3 full-arch cases per week, a caseload that supports a consistent, well-practiced workflow.
Does Summit Dental Care offer a guarantee on dental implants?
Yes. Summit Dental Care provides a five-year guarantee on dental implants for all patients, with a declining cost-waiver schedule in the rare event of implant failure (100% in year one, tapering to 20% by year five). The guarantee requires regular check-ups and hygiene visits and has standard exclusions. Full terms are available on our implant guarantee page.
Does Summit Dental Care have a prosthodontist on staff?
Yes. Dr. Kaaria Mwirigi, a prosthodontist, works alongside implantologist Dr. Joseph Gakonyo to design and fit the final full-arch prosthesis.
Is Summit Dental Care suitable for international or medical tourism patients?
Yes. Our clinic serves expatriates and international patients seeking full-arch implant treatment with globally recognized implant systems, generally at lower cost than comparable treatment in North America, Europe, or the Gulf region.
