About this study

This study aims to evaluate the clinical effectiveness of biomimetic abutments in implant restoration.

Read the detailed description

The biomimetic healing abutments were placed during the second-stage surgery, and the biomimetic prosthetic abutments were used to complete the implant restoration.

To assess soft tissues, digital models were collected in STL files at five time points: before the second-stage surgery, before the implant impression, immediately after restoration, six months after restoration, and 12 months after restoration. These models were analyzed using 3D software for model matching and measurement based on CBCT, focusing on the changes on soft tissue height, width, and volume.

Hard tissue evaluation was conducted through periapical radiographs taken at three time points: immediately after restoration, six months after restoration, and 12 months after restoration.

Additionally, general clinical conditions were assessed at the same three time points, evaluating parameters such as food impaction, plaque index, and gingival index.

What is being measured

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

  1. Changes in soft tissue contour

    Changes of soft tissue contour in height, width, and volume by matching digital models at different treatment stages.

    Measured: before the second-stage surgery, before the implant impression, immediately after restoration, six months after restoration, and 12 months after restoration

Secondary outcomes (4)
  1. Changes in hard tissue contour

    Changes of hard tissue contour in height through periapical radiographs using a long-cone paralleling technique with a film holder.

    Measured: immediately after restoration, six months after restoration, and 12 months after restoration

  2. Food impaction

    Incidence of food impaction: Dichotomous registration, 0 = Absent; 1 = Present.

    Measured: immediately after restoration, six months after restoration, and 12 months after restoration

  3. Plaque index

    0 = No plaque at the gingival margin; 1 = Thin plaque layer on the gingival margin, not easily visible on inspection but detectable by scraping with a probe; 2 = Moderate plaque accumulation at the gingival margin or interproximal surfaces; 3 = Heavy plaque accumulation in the gingival sulcus, at the gingival margin, or on interproximal surfaces. Mean values among the 6 sites were obtained (mesio-buccal, mid-buccal, disto-buccal, mesio-lingual, mid-lingual and disto-lingual).

    Measured: immediately after restoration, six months after restoration, and 12 months after restoration

  4. Gingival index

    0 = Normal gingiva; 1 = Slight gingival edema, no bleeding on probing; 2 = Gingival edema with bleeding on probing; 3 =Tendency for spontaneous bleeding or presence of ulceration. Mean values among the 6 sites were obtained (mesio-buccal, mid-buccal, disto-buccal, mesio-lingual, mid-lingual and disto-lingual).

    Measured: immediately after restoration, six months after restoration, and 12 months after restoration

Questions about this trial

What is this clinical trial studying?

A study testing using biomimetic abutments in people with Tooth Loss, run by Stomatological Hospital Affiliated with Fujian Medical University at 1 site in China.

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 4 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 11 Mar 2025. 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 China. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Hui Cheng, PhD (18960883888, ch_fujian@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in soft tissue contour (time frame: before the second-stage surgery, before the implant impression, immediately after restoration, six months after restoration, and 12 months after restoration). 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 11 Mar 2025.
