About this study
Official title: Bone Microarchitecture and Implant Stabilization in Atrophic Jaws Reconstructed With Bone Grafts Treated With Teriparatide
The aim of this triple blind randomized controlled trial will be to analyze the effect of a dose of teriparatide combined with a xenograft on bone augmentation of the maxillary sinus, to observe the microarchitecture of the newly formed bone and the primary and late stability of implants placed on these grafts. The sample is composed of 42 participants who have a clinical indication for maxillary sinus floor augmentation with bone grafting due to residual bone height less than or equal to 5mm for the installation of dental implants. Each side will be grafted with Bio-Oss® or Bio-Oss® combined with 1 dose (20 µg) of teriparatide (Forteo®). Three months after grafting, at the time of placement of dental implants, bone biopsies will be obtained using a short 2mm trephine bur. These bone cores will be submitted to histological and histomorphometric analysis. The stability of the implants will be measured, at the time of their installation, through the insertion torque, and through the use of resonance frequency equipment (Ostell®) in three moments: immediately and at 3 and 6 months after the installation of the dental implants.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TeriparatideDrug
Also called Teriparatide Pen Injector [Forteo]
mixture of 20μg of teriparatide, 0.64ml of saline solution with 1g of Bio -Oss® or 1g of Bio-Oss® will be mixed with 0.72ml of saline solution.
Maxillary Sinus AugmentationProcedure or surgery
Local anesthesia will be performed, mucoperiosteal flap will be raised to access the anterior wall of the maxillary sinus. Access to the maxillary sinus will be done through osteotomy, using a piezosurgery under irrigation with saline solution. Subsequently, the Schneider's membrane will be carefully lifted and, according to the randomization process, the graft material (Bio-Oss® mixed with saline solution or Bio-Oss® mixed with Forteo®) will be delivered for placement on the sinus floor maxilla below Schneider's membrane.Next, the access window to the maxillary sinus and Schneider's membrane will be protected. The mucoperiosteal flap will be repositioned and closed.
Dental Implant InstallationProcedure or surgery
Local anesthesia will be performed a mucoperiosteal flap will be raised in the area for implant placement and a bone core 10 mm high and 2 mm in diameter will be removed with a 2 mm trephine bur. The bone biopsied through this nucleus is part of the region where the implant will be installed, and the height of the sample depends on the surgical planning carried out previously (3-month radiographic control). The sequence of drills to place the implant will continue, installation of the implant itself and, finally, verification of the insertion torque and measurement of the resonance frequency in the already installed implant. The mucoperiosteal flap must be repositioned and sutured.
Bone graftCombination product
Also called Bio-Oss®
One arm:mixture of 20μg of teriparatide, 0.64ml of saline solution with 1g of Bio -Oss® In other arm: 1g of Bio-Oss® will be mixed with 0.72ml of saline solution.

The sample is composed of 42 participants who have a clinical indication for maxillary sinus floor augmentation with bone grafting due to residual bone height less than or equal to 5mm for the installation of dental implants. Each side will be grafted with Bio-Oss® or Bio-Oss® combined with 1 dose (20 µg) of teriparatide (Forteo®). Three months after grafting, at the time of placement of dental implants, bone biopsies will be obtained using a short 2mm trephine bur.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Teriparatide, Maxillary Sinus Augmentation and Dental Implant Installation in people with Bone Regeneration, run by Universidad de Valparaiso at 1 site in Chile.
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 2 inclusion and 18 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 30 Nov 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 Chile. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Contact Jessika Dethlefs, DDS, MSc (+56993231103, jessika.dethlefs@uv.cl), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Histology (time frame: 3 months). 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 NCT06061354, which also lists 45 linked publications.
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 30 Nov 2023.
