What is being measured
The primary outcome is the main question the study is designed to answer.
Hard Tissue (peri-implant bone)
Marginal bone loss will be assessed using CBCT measured in mm.
Measured: - Immediately postoperative - 3 months after implant placement - 9 months after implant placement.
Implant Stability
Implant stability will be evaluated using Osstell device based on resonance frequency analysis (ISQ values).
Measured: -immediately after implant placement -2 weeks postoperatively -4 weeks postoperatively - 3 months postoperatively - 9 months postoperatively
Secondary outcomes (2)
Soft Tissue
The peri-implant mucosa will be evaluated for signs of inflammation using the Modified Sulcus Bleeding Index (mSBI).
Measured: -After 3 months postoperatively. -After 9 months postoperatively.
Peri-implant probing depth
Probing depth will be assessed using a calibrated periodontal probe and measured in mm.
Measured: After 3 months postoperatively. -After 9 months postoperatively.

Questions about this trial
What is this clinical trial studying?
A study testing Delayed dental implant placement without photofunctionalization., Delayed dental Implant photofunctionalization before placement and Delayed dental Implant photofunctionalization and hyaluronic acid application before placement. in people with Tooth Loss and Surface Treatment, run by Mansoura University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 14 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hard Tissue (peri-implant bone) (time frame: - Immediately postoperative - 3 months after implant placement - 9 months after implant placement.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jul 2026; AzTrials last refreshed its copy on 6 Nov 2026.
