About this study
Official title: Implant Stability Changes Using Densah Burs Versus Magnetic Mallet Technique in Posterior Maxilla With Early Loading Protocol: A Randomized Clinical Trial
60 implants were placed in patients seeking implantation of their lost posterior maxillary teeth (premolar and molars) with normal bone height beneath the floor of the maxillary sinus. The patients were selected from those attending the outpatient clinic of the Oral \& Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University.
60 implants will be randomly and uniformly divided into two equal groups: Group 1: It was consisted of 20 inserted dental implants by Densah burs into healed posterior maxillary alveolar ridge with an early loading pattern.

Group 2: It was consisted of 20 inserted dental implants by Magnetic Mallet technique into healed posterior maxillary alveolar ridge with an early loading pattern.
Group 3: It was consisted of 20 inserted dental implants by Conventional Drilling technique into healed posterior maxillary alveolar ridge with an early loading pattern.

| Conventional Drilling group | Experimental | Not described Receives: Procedure: Conventional Drilling technique |
What is being measured
The primary outcome is the main question the study is designed to answer.
Implant stability
Implant stability was assessed at the time of implant insertion, 1 month and 2 months after surgery. The analysis of resonance frequency analysis (RFA) was made using an Osstell Mentor apparatus. The smart peg was attached to the dental implant. The RFA value was measured 4 times in 4 directions (every 90°). The results were expressed as implant stability quotient (ISQ) and averaged for each implant. The ISQ scale ranges from 0 to 100. The values less than 60 indicate low implant stability, values from 60 to 69 indicate medium stability, while values from 70 to 79 indicate high stability.
Measured: 2 months

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

Questions about this trial
What is this clinical trial studying?
A study testing Densah burs, Magnetic Mallet technique and Conventional Drilling technique in people with Tooth Loss, run by Mansoura University at 1 site in Egypt.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Mar 2026. 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 Egypt. 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?
Implant stability (time frame: 2 months). 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 2 Mar 2026; AzTrials last refreshed its copy on 28 Oct 2026.
