About this study

Official title: Evaluation of the Effects of Alternating Rapid Maxillary Expansion and Facemask Use in Cases of Class III Malocclusion Caused by Maxillary Retrognathia- A Prospective, Randomized Clinical Trial

Diverse viewpoints exist regarding the correlation between the conventional rapid maxillary expansion (RME) and facemask approach and the alternative RME and facemask hybrid technique (Alt-RAMEC) in terms of the degree of maxillary protraction. The findings of the study may offer a novel approach to protocol selection based on the anomaly's degree of severity. The objective of this investigation is to assess and contrast the skeletal and dentoalveolar outcomes of three distinct Alt-RAMEC techniques.

Read the detailed description

Alternating rapid maxillary expansion and constriction (Alt-RAMEC) procedure is one of the most frequently used methods in the treatment of Class III cases caused by maxillary retrognathia. The objective of this investigation is to conduct a comparative analysis of the skeletal and dentofacial outcomes of three distinct techniques for maxillary protraction Following the primary recording, the patients were evaluated using bonded-type rapid maxillary expansion (RME) devices and three discrete Alt-RAMEC techniques (1, 3, and 5 weeks). Lateral cephalograms were obtained from a sample of 40 patients (18 males and 22 females) with a mean age of 10.64 ± 0.98. These images were taken both before (T1) and after the 6th month of facemask treatment (T2), and were subjected to total and local superimpositions. The Wilcoxon Sign, Kruskal-Wallis and Mann-Whitney U tests were used to evaluate the data.

Conditions: Face Mask, Rapid Maxillary Expansion, Maxillary Retrognathism
Being tested: Delaire Face Mask (M0774-01, Leone S.p.A., Florence, Italy) for first group, Delaire Face Mask (M0774-01, Leone S.p.A., Florence, Italy) for second group, Delaire Face Mask (M0774-01, Leone S.p.A., Florence, Italy) for third group

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Delaire Face Mask (M0774-01, Leone S.p.A., Florence, Italy) for first groupDevice
Also called (Fabricated for every patient) Bonded-type Expansion Device
The study involved the fabrication of occlusal-coverage bonded type RME devices utilizing Hyrax screws (A0620-11, Leone S.p.A., Firenze, Italy). Each patient in Group 1 (classical RME method) was instructed to open Hyrax screw twice a day for a week. At the end of the respective periods (1 week), the screws were fixed with ligatures, and the patients were evaluated.
Face-mask treatment was subsequently started after RME. Totaling 700 g of extraoral traction force applied to maxilla. Patients were advised to wear Delaire type facemasks (M0774-00, Leone SpA) 14-16 hours a day for 6 months.
Delaire Face Mask (M0774-01, Leone S.p.A., Florence, Italy) for second groupDevice
Also called (Fabricated for every patient) Bonded-type Expansion Device
The same fabrication of occlusal-coverage bonded type RME devices were utilized Hyrax screws (A0620-11, Leone S.p.A., Firenze, Italy) in Group 2. Each patient in Group 2 (3-week Alt-RAMEC protocol), the patients were instructed to activate Hyrax screw twice a day for one week, close the screw for following week, and open the screw over the third week. At the end of the respective periods (3 weeks), the screws were fixed with ligatures, and the patients were evaluated.
Face-mask treatment was subsequently started after RME. Totaling 700 g of extraoral traction force applied to maxilla. Patients were advised to wear Delaire type facemasks (M0774-00, Leone SpA) 14-16 hours a day for 6 months.
Delaire Face Mask (M0774-01, Leone S.p.A., Florence, Italy) for third groupDevice
Also called (Fabricated for every patient) Bonded-type Expansion Device
The same fabrication of occlusal-coverage bonded type RME devices were utilized Hyrax screws (A0620-11, Leone S.p.A., Firenze, Italy) in Group 3. Each patient in Group 3 (5-week Alt-RAMEC protocol), the patients were instructed to activate Hyrax screw twice a day for one week, close the screw for following week, and open the screw over the third week. The aforementioned screw open-close procedure was implemented over a period of five weeks. At the end of the respective periods (5 weeks), the screws were fixed with ligatures, and the patients were evaluated.
Face-mask treatment was subsequently started after RME. Totaling 700 g of extraoral traction force applied to maxilla. Patients were advised to wear Delaire type facemasks (M0774-00, Leone SpA) 14-16 hours a day for 6 months.

Questions about this trial

What is this clinical trial studying?

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 5 inclusion and 2 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 22 Jun 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 Turkey (Türkiye). 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?

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?

Evaluation of Skeletal, Dental, and Soft Tissue Angular Measurements (time frame: 6 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 NCT05913076.

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 22 Jun 2023.
