An interventional study of ReActive Implant System (Internal Tri-Lobe Platform) and Legacy II Implant System (Internal Hexagonal Platform) in Jaw, Edentulous, Edentulism, Complete and Peri-implant Bone Loss, sponsored by Gulf Medical University. Completed at 1 site in United Arab Emirates. Open to male participants aged 45 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-17.
Sponsored by Gulf Medical University · Not applicable, Interventional, and Treatment
Objective: Compare changes in crestal bone height and peri-implant bone density using cone-beam computed tomography (CBCT) at baseline, 6 months, and 12 months post-placement.
Participants \& Setup: 14 fully edentulous male patients (aged 45-60) received two mandibular canine implants. Comparison Groups: Group I (n = 7) received internal tri-lobe implants (ReActive System), and Group II (n = 7) received internal hexagonal implants (Legacy II System).
Intervention: Implants were immediately loaded with ball attachments to retain lower overdentures.
122 studies on the registry are indexed under Jaw, Edentulous; 20 are open to participants now.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Patients fitted with the ReActive Implant System (internal tri-lobe platform).
Device: ReActive Implant System (Internal Tri-Lobe Platform)
Patients fitted with the Legacy II Implant System (internal hexagonal platform).
Device: Legacy II Implant System (Internal Hexagonal Platform)
Bilateral surgical placement of two 3.7 × 13 mm tapered, threaded titanium-alloy dental implants featuring a Soluble Blast Media (SBM) textured surface and a color-coded internal tri-lobe platform in the mandibular canine regions. Implants are placed using a one-stage, non-submerged surgical technique and fitted with metallic ball abutments (2 mm cuff). Implants are immediately loaded to retain a mandibular complete overdenture picked up directly with self-curing acrylic resin.

Ran from Dec 2024 to primary completion in May 2026, 17 months.
Of 58 non-industry interventional studies with no phase under Jaw, Edentulous, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 30. This study's 17 months is close to that.
Counting every sponsor, half of 66 studies reached it within 20 months; a quarter within 12 and three quarters within 38.
