Impact of Implant Position on Bone Loss in Dental Procedures
The Influence of Vertical Implant Position With Immediate Provisionalization on the Marginal Bone Loss in Thick Versus Thin Phenotype. A Randomized Controlled Clinical Trial.
NA · Cairo University · NCT06177275
This study tests whether placing dental implants slightly below the bone level helps reduce bone loss and improve appearance for people missing upper front or side teeth.

What this trial studies
This clinical trial investigates how the vertical position of dental implants affects marginal bone loss in patients with different soft tissue phenotypes. It compares the outcomes of placing implants 2 mm below the crest of the bone versus at the crest level in patients with single missing upper anterior or premolar teeth. The study aims to determine the optimal implant placement technique to enhance aesthetic outcomes and minimize bone resorption. Participants will be monitored for one year to assess the impact of the implant position on bone health and aesthetic results.
Who should consider this trial
Good fit: Ideal candidates include adults over 18 with a single missing upper anterior or premolar tooth and sufficient bone width.
Not a fit: Patients with inadequate bone volume, local root remnants, or those who smoke heavily may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved aesthetic outcomes and reduced bone loss for patients receiving dental implants.
How similar studies have performed: Previous studies have shown promising results regarding the impact of implant positioning on bone loss, suggesting that this approach is supported by existing literature.
