July 8, 2026 updated by: Mansoura University

Enhancing Implant Success in the Posterior Maxilla: The Impact of Photofunctionalization and Hyaluronic Acid

This randomized clinical trial evaluates the effect of UV photofunctionalization and hyaluronic acid on dental implants placed in the posterior maxilla. Clinical and radiographic outcomes will be assessed during follow-up

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study compares conventional implants, UV-photofunctionalized implants, and UV-photofunctionalized implants with hyaluronic acid application in the posterior maxilla. Implant stability and peri-implant tissue changes will be evaluated clinically and radiographically during follow-up.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients with missed single tooth or multiple teeth in posterior maxilla.
  • Patients Free from any para-functional habits.
  • Patient with Adequate inter-arch relation and inter-occlusal space to accommodate the prosthetic restoration.
  • Patient with good oral hygiene.
  • Patients Willing to participate in the study's follow-up intervals.

Exclusion Criteria:

  • Patients with any local or systemic disease that absolute contraindicate implant placement or surgery.
  • Pregnancy.
  • Patients with any pathological lesion or aggressive periodontal disease at the planned surgical site.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Hard Tissue (peri-implant bone)
Time Frame: - Immediately postoperative - 3 months after implant placement - 9 months after implant placement.
Marginal bone loss will be assessed using CBCT measured in mm.
- Immediately postoperative - 3 months after implant placement - 9 months after implant placement.
Implant Stability
Time Frame: -immediately after implant placement -2 weeks postoperatively -4 weeks postoperatively - 3 months postoperatively - 9 months postoperatively
Implant stability will be evaluated using Osstell device based on resonance frequency analysis (ISQ values).
-immediately after implant placement -2 weeks postoperatively -4 weeks postoperatively - 3 months postoperatively - 9 months postoperatively

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Soft Tissue
Time Frame: -After 3 months postoperatively. -After 9 months postoperatively.
The peri-implant mucosa will be evaluated for signs of inflammation using the Modified Sulcus Bleeding Index (mSBI).
-After 3 months postoperatively. -After 9 months postoperatively.
Peri-implant probing depth
Time Frame: After 3 months postoperatively. -After 9 months postoperatively.
Probing depth will be assessed using a calibrated periodontal probe and measured in mm.
After 3 months postoperatively. -After 9 months postoperatively.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2025

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
