Brief summary

The goal of this clinical trial was to evaluate whether the topical application of a combination of dexamethasone, ascorbic acid, and β-sodium glycerophosphate could enhance implant osseointegration in adult dental implant patients. The main question it aimed to answer was: Did the combined topical use of these agents improve implant stability during the healing phase? Researchers compared intervention implants (which received the topical agents at the implant site) to control implants (which received standard placement without topical application) within the same participant, in order to assess differences in implant stability and osseointegration. Participants: Underwent dental implant surgery. Received both the topical treatment and the standard procedure, applied to different implant sites. Returned for follow-up visits, where implant stability was measured using resonance frequency analysis (RFA) at predefined time intervals.

Detailed description

This randomized clinical trial was conducted to investigate the effect of the topical application of a combination of dexamethasone, ascorbic acid, and β-sodium glycerophosphate on the osseointegration of dental implants. The rationale behind the study was based on existing evidence suggesting that these agents may enhance bone healing, reduce inflammation, and support mineralization when applied locally. Each participant received two dental implants: one designated as the intervention site (treated with the topical combination of the three agents at the time of implant placement), and the other as the control site (placed without any topical application). This split-mouth design allowed intra-individual comparison, minimizing the influence of patient-related variability. Implant stability was assessed using resonance frequency analysis (RFA) at four follow-up intervals to evaluate differences in osseointegration between the two sites. The study aimed to determine whether the adjunctive use of these agents could improve early implant stability, potentially contributing to more predictable outcomes in dental implantology. No investigational drugs or devices were used beyond standard clinical tools. The study was approved by a local ethics committee, and informed consent was obtained from all participants prior to enrollment.

Interventions

DRUGTopical Application of Dexamethasone, Ascorbic Acid, and β-Sodium Glycerophosphate

A topical combination of dexamethasone (anti-inflammatory), ascorbic acid (antioxidant), and β-sodium glycerophosphate (mineralization support) was applied directly to the implant site during surgery. The intervention aimed to enhance early osseointegration by modulating local biological responses.

DOUBLE (Subject, Outcomes Assessor)

Masking description

This was a single-blind study in which participants were unaware of which implant site received the topical intervention. The care provider and investigator were aware of the allocation. Outcome assessors were masked to the assignment to ensure unbiased evaluation of implant stability measurements.

Intervention model description

This study followed a split-mouth design, analyzed using a parallel assignment model at the implant level. Each participant received two dental implants: one implant served as the intervention site and received a topical application of dexamethasone, ascorbic acid, and β-sodium glycerophosphate, while the other implant served as the control site and received standard placement without any topical application. Both implants were placed during the same surgical session, allowing for intra-patient comparison under identical clinical and systemic conditions. Implant stability was assessed at multiple time points using resonance frequency analysis (RFA).

Primary

MeasureTime frameDescription
Change in Implant Stability Measured by Implant Stability Quotient (ISQ) Using Resonance Frequency Analysis (RFA)At baseline (day of surgery), 4 weeks, 8 weeks, and 16 weeks post-surgeryImplant stability will be assessed using resonance frequency analysis (RFA), with results reported as Implant Stability Quotient (ISQ) values. The ISQ scale ranges from 1 (lowest stability) to 100 (highest stability). Higher ISQ values indicate better implant stability and osseointegration.
