Can a slimmer dental implant handle immediate chewing pressure?
NCT ID NCT03917927
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This study follows adults who receive a narrow Eztetic dental implant in the front part of the upper or lower jaw, with a temporary tooth attached right after surgery. The goal is to see how many implants survive and how the surrounding bone holds up over two years. Researchers will also check bone level changes around the implant compared to the time of placement.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Eztetic dental implant system (narrow diameter dental implant)
- What this could lead to
- If successful, this could support the use of narrow dental implants for immediate loading in the front of the mouth, potentially shortening treatment time for people with missing teeth.
- What could go wrong
- This is an observational study, not a randomized trial, so results may not prove the implant is better than other options. Implant failure or bone loss around the implant are possible risks.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients of either sex and at least 18 years of age 2. Patients for whom a decision has already been made to use a dental implant for the restoration of existing partial edentulism in the anterior (central and lateral incisors), canine or pre-molar regions in the mandible or maxilla. Placing implant in canine region should be in a healed site (not for immediate extraction) 3. Immediate extraction or a prior extracted site 4. Intact buccal table as verified by Cone Beam Computed Tomography (CBCT) or radiography during surgery. If absent, patient should be excluded from enrollment in the study. 5. Patients must be physically able to tolerate conventional surgical and restorative procedures. 6. Patients with a facial lingual width of at least 5.1mm and inner tooth width of at least 6mm. 7. Patients having a thick gingival biotype (based on the lack of transparency of the periodontal probe through the gingival margin while probing the buccal sulcus) will be preferred but lack of this characteristic will not disqualify a patient from inclusion in this study. 8. Presence of opposing dentition with a functional occlusion that permits the restoration with a non-occluding provisional prosthesis. 9. Patients who provide a signed informed consent; a patient having implant placement surgery will continue participation in the study regardless of whether or not they receive restorative treatment according to protocol (protocol deviation) 10. Patients who agree to be evaluated for each study visit. 11. Minimum primary stability, insertion torque \> 35Ncm (this will be a criteria that is met at the time of surgery) Exclusion Criteria: 1. Patients with known systemic diseases such as uncontrolled diabetes, endocrine disease, heart disease, immuno-compromised, or mental disorders. 2. Patients with current use of non-steroidal anti-inflammatory drugs, bisphosphonates or corticosteroid treatments. 3. Patients with active infection or severe inflammation in the areas intended for implant placement. 4. Prisoners 5. Patients with a \> 10 cigarette per day smoking habit. 6. Patients with a history of therapeutic radiation to the head or jaw. 7. Patients in need of bone grafting at the site of the intended implantation site(s). 8. Patients who are known to be pregnant at the screening visit or planning to become pregnant within 6 months of study enrollment. 9. Patients with evidence of severe parafunctional habits such as bruxing or clenching. 10. Patients with HIV or Hepatitis infection 11. Patients who have previously failed implants at the site intended for study implant placement 12. Patients in need of other treatments or surgeries at a site adjacent to the intended implantation site 13. Patients with a history of severe periodontal disease
