Custom tooth-shaped implants take on standard screws in denture support trial
NCT ID NCT07284680
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares a custom-made bio-implant (shaped like a natural tooth root) to a standard screw-type implant for supporting partial dentures in people missing back teeth. Eight participants with a specific tooth arrangement received both types of implants. Researchers will measure bone levels and gum health around the implants and nearby teeth at 0, 3, and 6 months after the final denture is placed.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bio-implant root analogue (custom-shaped implant) and conventional screw-type implant
- What this could lead to
- If successful, this could show that a custom-shaped bio-implant works as well as or better than standard screw implants for supporting partial dentures, potentially offering a more natural option.
- What could go wrong
- This is a very small study with only 8 participants, so results may not apply to everyone. It is also early-stage and only follows patients for 6 months, so long-term success is unknown.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * The patients had bilateral mandibular free-end partially edentulous cases with a pier abutment or a planned presence of pier abutment. * The edentulous space mesial to the pier abutment has a hopeless tooth or root that was used for bio-implant insertion or conventional screw-type implants. * Healthy patients with no systemic disease that can affect the implant surgery. This was verified by medical history in addition to a report from the physician. * The patients have had dentulous maxillary jaw and mandibular free-end saddle for at least 6 months. * Class I maxillo-mandibular relationship with adequate inter-arch distance. Exclusion Criteria: * Patients with metabolic disorders that affect osseointegration such as uncontrolled diabetes mellitus, immune disorders, and osteoporosis. * Patients with heavy smoking habit * Patients complaining of severe temporomandibular joint disorder.
