About this study

Official title: Identification of Biological Responses as a Causal Link for the Increased Peri-implantitis in Patients With History of Periodontitis

This prospective parallel, double-blind, four-arm randomised controlled clinical study is planned to assess the difference in the level of the inflammatory biomarkers expressed following the placement of the first dental implant in patients with history of periodontitis (successfully treated) and healthy controls without the disease, during implant osseointegration period. The subjects in both groups will also be randomised to receive one of the two types of implants provided which have different surface treatment.

Read the detailed description

This is a prospective, parallel, double-blind, four-arm randomised clinical control study, aims to investigate the changes of clinical parameters and pro-inflammatory biomarkers expression and the shift following the first dental implant placement in patients who have been successfully treated for periodontitis, compared with healthy control without the disease.

The main questions to answer are:

  1. Why do patients with history of periodontitis are at a greater risk to develop peri-implantitis than patients without history of periodontitis?
  2. Is there any difference in the microbial composition, histological and immunological reaction of the host's dental plaque, peri-implant soft tissue, gingival crevicular fluids (GCF) of adjacent teeth and peri-implant sulcular fluids (PISF) following implant placement in patients with and without a history of periodontitis? The test group will consist of subjects with stabilised periodontitis, whilst the control group will consist of healthy patients with no history of periodontitis, as identified via history taking and clinical screening. Periodontal condition will be determined based on the new 2017 periodontal classification. All participants in both groups will be randomised to receive one of two types of implants with different surface treatment.

Clinical measurement, GCF and PISF will be collected around the single implant and adjacent teeth, at the following stages (time-point):

  • Baseline (pre-operative)
  • After implant placement (prior to the second stage surgery)
  • After implant exposure (prior to the crown restoration)
  • 3-month after the implant is restored
  • Soft tissue will be obtained during the first stage (baseline) and second stage implant surgery (post-operative) and analysed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Level of matrix metalloproteinase (MMP)-8 expressed in the gingival crevicular and peri-implant sulcular fluids during the early-stage of dental implant placement

    To measure the absolute quantification of MMP-8 level expressed during the implant osseointegration period in all study groups via ELISA method.

    Measured: From baseline (1st time-point (TP1)) to 1st stage surgery (implant placement - TP2), after 2nd stage surgery (implant exposure (TP3) and 3-months after implant crown restoration (final visit- TP4)

Secondary outcomes (4)
  1. Shift of the microbial composition in the supragingival dental plaque, identified via 16S rRNA next generation sequencing

    Identification and comparison of supragingival dental plaque bacteria species/genus and the shift of the bacterial composition during the early-stage of dental implant placement between study groups

    Measured: From baseline (1st time-point (TP1)) to 1st stage surgery (implant placement - TP2), after 2nd stage surgery (implant exposure (TP3) approximately 3 months after the 1st stage surgery) and 3-months after implant crown restoration (final visit- TP4)

  2. Shift of proteome profiles in the gingival crevicular and peri-implant sulcular fluids during the early-stage of dental implant placement

    To assess the protein profile and levels of expression of the pro-inflammatory cytokines in GCF and gingival tissue via liquid chromatography-electrospray ionization tandem mass spectrometry (LC-MS) proteomic analysis following osseointegration.

    Measured: From baseline (1st time-point (TP1)) to 1st stage surgery (implant placement - TP2), after 2nd stage surgery (implant exposure (TP3) approximately 3 months after the 1st stage surgery) and 3-months after implant crown restoration (final visit- TP4)

  3. Histological changes in the peri-implant soft tissue before and after implant placement

    Number and co-localisation of cells with MMP-8, pro-inflammatory (M1)- and anti-inflammatory (M2)-related cytokines via hematoxylin and eosin staining, immunohistochemistry and immunofluorescence analysis

    Measured: Between first stage (baseline/pre) and second stage implant surgery (post-operative) at 3 months after the first surgery

  4. Changes in the clinical parameters during the early-stage implant placement

    To assess intra-oral clinical parameters changes (i.e. patient-level and tooth-level mean periodontal pocket depth (mm) and clinical attachment level (mm); full mouth plaque score (%) and bleeding score (%)) following the first dental implant placement, each time-point (TP). The deeper the depth/higher the level or percentage means the worse the condition is.

    Measured: From baseline (1st time-point (TP1)) to 1st stage surgery (implant placement - TP2), after 2nd stage surgery (implant exposure (TP3) approximately 3 months after the 1st stage surgery) and 3-months after implant crown restoration (final visit- TP4)

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 13 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 18 Oct 2023. 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 Malaysia. 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.

Are results available for this study?

Results are not available in the source record.

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?

Level of matrix metalloproteinase (MMP)-8 expressed in the gingival crevicular and peri-implant sulcular fluids during the early-stage of dental implant placement (time frame: From baseline (1st time-point (TP1)) to 1st stage surgery (implant placement - TP2), after 2nd stage surgery (implant exposure (TP3) and 3-months after implant crown restoration (final visit- TP4)). 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 18 Oct 2023.
