Sources & studies

Our clinical claims are grounded in peer-reviewed research. Cost figures are market estimates compiled separately (see methodology) and are not from these studies.

1. Soto-Peñaloza D, et al. (2017). The all-on-four treatment concept: Systematic review.
   J Clin Exp Dent · View source ↗

   24 studies, 11,743 implants. Source for survival framing (99.8% is a conditional >24-month rate; ~94.8% lowest long-term), acrylic fracture as the most common prosthetic complication, and the "evidence is limited" caveat.

2. Retrospective cohort (1-year) (2021). Complications and survival of All-on-4 implants and restorations.
   PMC8165050 · View source ↗

   544 implants / 126 patients. Implant survival 98.2% vs restoration survival 94.4% — prosthesis failures exceed implant failures; early-healing complication clustering and risk factors (posterior maxilla).

3. University of Michigan retrospective analysis (2020). Metal-acrylic vs. monolithic zirconia full-arch prostheses: cost and survival.
   Int J Oral Maxillofac Implants 35(2):395-405 · View source ↗

   74 arches, mean 8.7-yr follow-up. Zirconia cost ~$7,829 more per arch to fabricate but 5-yr prosthetic survival 93.7% vs 83.0% for metal-acrylic, with similar lifetime maintenance. Our key materials trade-off.

4. Papaspyridakos P, et al. (2024). Survival and complications of monolithic zirconia implant fixed complete dentures.
   J Prosthodont (10.1111/jopr.13922) · View source ↗

   115 zirconia full-arch prostheses, up to 6 yr. 98.6% prosthesis survival; most complications minor and chairside-fixable (screw-channel filling loss, porcelain chipping).

5. Systematic review (2025). Monolithic zirconia complete-arch implant prostheses: survival and complications.
   Prosthesis (MDPI) 5(2):29 · View source ↗

   7 studies, mean 49.7-mo follow-up. Average prosthesis survival ~97.2% with minimal complications; long-term (>5 yr) data still limited.
