About this study

Official title: Comparative Histological and Histomorphometric Results of Six Biomaterials Used in Two-stage Maxillary Sinus Augmentation Model After 6-month-healing

Objectives: The aim of the study was to compare histological and histomorphometric results of six bone substitute materials used as graft in two-stage maxillary sinus augmentation model, after 6-month-healing.

Read the detailed description

Materials and Methods:

A two-stage sinus augmentation was carried out in six patients using mineralized solvent-dehydrated bone allograft (MCBA), freeze-dried mineralized bone allograft (FDBA), anor-ganic bovine bone (ABB), equine-derived bone (EB); synthetic micromacroporous biphasic calcium-phosphate block consisting of 70% beta-tricalcium phosphate and 30% hydroxyap-atite (HA-β-TCP 30/70), or bioapatite-collagen (BC).

What is being measured

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

  1. to perform biopsies from each six augmented site using to compare, histologically and histomorphometrically, the percentages of newly formed bone, residual grafted material, and marrow spaces.

    After 6 months clinical and radiographic examinations were undertaken and each patient was reappointed for biopsy at the time of implant placement in the same location. Under local anesthesia, a full thickness flap was raised, a biopsy was performed using a 3.5 mm tre-phine bur under sterile saline solution irrigation, guided by the radiographic/surgical template in the selected implant site. A total of six bone samples was retrieved from the occlusal aspect to the alveolar crest, one from each augmented site to compare histologically and histomorphometrically the different materials.

    Measured: 6 month-healing after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Sinus floor augmentation in people with Atrophy and Jaw, Edentulous, Partially, run by University of Roma La Sapienza.

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 0 inclusion and 1 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: finished, as of the sponsor's last update on 12 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

to perform biopsies from each six augmented site using to compare, histologically and histomorphometrically, the percentages of newly formed bone, residual grafted material, and marrow spaces. (time frame: 6 month-healing after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03496688, which also lists 1 linked publication.

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 12 Apr 2018.
