Shorter wait for dental implants? trial tests 4-Month vs 6-Month healing
NCT ID NCT07746869
First seen Aug 05, 2026 · Last updated Aug 06, 2026 · Updated 1 time
Summary
This study compares two healing periods—4 months versus the standard 6 months—after a tooth extraction with socket preservation, before placing a dental implant. The goal is to see if the shorter wait provides similar implant stability and bone quality. Participants will be adults needing a single-tooth implant, and the trial will measure implant stability, bone changes, and tissue health over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Equine-derived enzymatically treated biomaterials (BIOTECK system) and OITECH implant system
- What this could lead to
- If successful, this could shorten the time between tooth extraction and dental implant placement, reducing patient discomfort and treatment duration.
- What could go wrong
- The trial is small (40 participants) and early-stage, so results may not apply broadly. There is a risk that 4-month healing may not provide the same implant stability as 6 months.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Potential participants will be identified among patients treated at the University of Granada's Clinic for Advanced Comprehensive Dentistry and Implantology and Periodontology and Implants, either during routine diagnostic visits or through internal referrals. Patients who have a tooth-preferably an anterior tooth or premolar-for which extraction is clinically indicated and who express their intention to restore the area through the subsequent placement of a dental implant will be considered potential candidates.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age: ≥ 18 years. 2. Good general health. Need for extraction of incisors, canines, or premolars due to caries, endodontic complications, root fracture, or prosthetic reasons. 3. Presence of three intact alveolar walls following tooth extraction, with a defect in the vestibular wall (\<50%). 4. Need for treatment with single-tooth implants, with adjacent teeth and occlusal antagonists present. 5. Sufficient available bone, as assessed by CBCT, for the placement of implants 3.6 mm in diameter and 10 mm in length. 6. Periodontal health with intact or reduced periodontium. Full-mouth plaque and bleeding scores \< 20%. 7. Ability and willingness to follow the study procedures and instructions. Exclusion Criteria: 1. Compromised health status. Presence of any systemic condition, such as uncontrolled diabetes mellitus, cancer, HIV, disorders that impair wound healing, chronic high-dose steroid therapy, intravenous and oral bisphosphonate therapy, metabolic bone diseases, a history of head and neck radiation, or any other immunosuppressive therapy that contraindicates oral surgical treatment. 2. Absence of adjacent teeth or opposing occlusal teeth. 3. The missing tooth is a molar. 4. More than one defect in the bone wall or a buccal defect \>50%. 5. Allergy or hypersensitivity to medications or any product used during the study. 6. Regular use of tobacco (defined as \>1 cigarette per day) or chewing tobacco, even within the 3 months prior to enrollment. 7. Untreated periodontitis. 8. Acute periapical or periodontal infection. 9. Oral plaque and/or bleeding \> 20%.
