Marginal Bone Level Around Dental Implants in Periodontitis Patients

This study evaluates and compares marginal bone level changes around dental implants with two different surface characteristics in patients with a history of periodontitis. Participants will receive dental implants and will be followed up for one year to assess bone level changes around the implants.

Evaluation of Fluid Biomarkers Around Implants Exhibiting Early Stage Periimplant Bone Loss

This study aimed to compare biological mediators known to be important in peri-implant diseases in implants with and without early stage marginal bone loss. A total of 118 implants in 59 patients were designated as test and control groups. The radiographic and periodontal data of the included implants, along with peri-implant sulcus fluid samples, were evaluated.

Autogenous Soft Tissue Grafts for Primary Closure Over Immediately Placed Dental Implants

The aim of this interventional study is to evaluate the best method to place the autogenous soft tissue grafts for primary closure over immediately-placed dental implants. \- Primary hypothesis, there is no differences between the two techniques of placement.

Subcrestal vs Juxtacrestal PRAMA Implants With Variable Necks

The goal of this clinical trial is to understand how different implant neck designs and placement depths affect the surrounding bone and peri-implant tissue (the tissue around a dental implant) in adults who need implants in the back areas of the mouth (molars and premolars). The main questions it aims to answer are: Does placing implants deeper under the bone crest (subcrestally) help preserve more bone and peri-implant tissue over time? Do implants with longer, conical necks and micro-threaded surfaces result in more stable peri-implant tissue than implants with shorter necks? Researchers will compare three types of one-piece dental implants with different neck heights (short, standard, and long), placed at different depths in the jawbone, to determine which combination better maintains bone and peri-implant tissue levels. Participants will: Receive two dental implants in the posterior upper or lower jaw Be randomly assigned to one of three groups depending on implant neck design and placement depth Undergo implant surgery using a digital workflow, with healing over three months Be rehabilitated with custom zirconia bridges Return for regular clinical and imaging checkups over a period of at least 3 years This study aims to generate evidence that helps clinicians choose implant designs and techniques that promote long-term peri-implant tissue health.

Comparative Evaluation Between One-piece and Two-piece Implants Supporting Mandibular Screw-retained All-On-Four Full-arch Prosthesis on Peri-implant Bone Changes.

Evaluating the bone changing after receiving one-piece implants supported full arch prosthesis compared to the conventional two-piece implants.
