About this study
Official title: Marginal Bone Loss Around the Implant of Screw-retained Implant Restorations in the Esthetic Zone Using PEEK With Composite Veneering Versus Monolithic Zirconia Restorations Using a Fully Digital Workflow: A Randomized Controlled Clinical Trial
This study compares two different materials used for screw-retained dental implant restorations in the front of the upper jaw (the "esthetic zone"). The goal is to determine which material is better at preserving the bone level around the implant over time and how this will affect the survival rate of the restorations
Read the detailed description
Purpose of the Study
The primary purpose of this randomized controlled clinical trial is to compare two specific materials used for screw-retained dental implant restorations in the "esthetic zone" (the front of the upper jaw) to see which one better preserves the surrounding bone.
Core Research Objective
The study aims to evaluate whether PEEK (Polyetheretherketone) veneered with composite is superior to monolithic zirconia in decreasing marginal bone loss around dental implants.
The Scientific Rationale
Researchers are investigating these materials for several key reasons:
- Stress Distribution:** PEEK has an elastic modulus (flexibility) similar to human bone. It is believed this may help avoid high-stress transfer at the bone-implant interface and reduce "stress shielding," which can lead to bone loss.
- Improving on Current Standards:** While monolithic zirconia is popular due to its high esthetic potential and biocompatibility, it is very rigid, and common failures include the chipping of veneering porcelain.
- Establishing Gold Standards:** The study seeks to determine a "gold standard" for screw-retained restorations that can maximize implant survival rates and enhance the quality of life for partially edentulous patients.
- Clinical Guidance:** The findings are intended to provide clinicians with specific precautions and recommendations for implant planning in the esthetic zone to enhance overall treatment success.
Primary and Secondary Outcomes
To fulfill this purpose, the study measures two main factors:
- Primary Outcome: The amount of marginal bone loss** (measured in millimeters) using digital X-rays at 6 and 12 months.
- Secondary Outcome:The survival rate of the different types of restorations over the one-year follow-up period.
- Conditions
- Partial Edentulism Class IV
- Being tested
- PEEK (Polyetheretherketone) screw-retained implant restoration veneered with composite, Monolithic zirconia screw-retained implant restoration
- Keywords
- Marginal Bone Loss, Survival rate, Screw retained FPD, Zirconia, PEEK
What participants receive

PEEK (Polyetheretherketone) screw-retained implant restoration veneered with compositeProcedure or surgery
Also called PEEK
To distinguish the interventions in this specific study from those in other clinical trials, the following unique technical and procedural details should be noted:
- Specific Material Combination: The primary intervention uses PEEK (Polyetheretherketone) specifically veneered with Visio-lign composite**, a combination chosen to mimic the elastic modulus of human bone and reduce stress shielding.
- Targeted Anatomical Site: The study is exclusively limited to the maxillary esthetic zone** (upper front teeth), where both mechanical stress and esthetic demands are highest.
- Fully Digital Workflow: Unlike studies that may use conventional impressions, this protocol utilizes a fully digital workflow**, including digital intraoral scans and CAD/CAM fabrication for both the PEEK and zirconia restorations.
- Prosthetically Driven Surgical Guidance:** The placement of the two implants is "prosthetically driven," meaning the final tooth position dictates the surgey
Monolithic zirconia screw-retained implant restorationProcedure or surgery
Also called Zirconia
In this study, the comparator group (the control group) receives a monolithic zirconia screw-retained restoration. This group serves as the standard clinical benchmark against which the experimental PEEK-composite material is measured.
The specific details that distinguish this intervention from others include:
- Material Selection: The restoration is made of monolithic zirconia**, a high-strength ceramic known for its biocompatibility and esthetic potential, but which is significantly more rigid than the experimental PEEK material.
- Fully Digital CAD/CAM Workflow: Unlike traditional methods, the zirconia restoration is designed and fabricated using a fully digital workflow**, including digital intraoral scans and computer-aided manufacturing.
- Specific Anatomical Placement: This intervention is applied specifically to two dental implants** located in the maxillary esthetic zone
| Study group | Role | What they receive |
|---|---|---|
| Marginal bone loss around Monolithic Zirconia screw-retained implant restoration | Active comparator | The "gold standard" or comparator group (Control Group) consists of Monolithic Zirconia screw-retained restorations.
The specific intervention for this group includes the following steps:
Surgical Phase: Each participant receives two dental implants installed in the esthetic areas of the maxillary arch.
Surgical Guidance: The implants are prosthetically driven and installed with the help of digitally constructed surgical guides.
Provisional Phase: Temporary (provisional) restorations are loaded immediately after implant insertion and worn during the healing phase.
Final Restoration: After three months of healing, the final fixed partial denture-made of monolithic zirconia-is inserted.
Workflow: The entire process follows a fully digital workflow.
Maintenance: Patients receive regular maintenance instructions and are recalled for follow-up assessments Receives: Procedure: Monolithic zirconia screw-retained implant restoration |
| Marginal bone loss around PEEK screw-retained implant restoration veneered with composite | Experimental | In this clinical trial, the intervention group receives PEEK (Polyetheretherketone) screw-retained restorations veneered with composite
The specific steps and components for this group include:
* Implant Placement:** Each participant receives two dental implants in the upper front (maxillary esthetic) zone.
* Surgical Guidance:** The implants are placed using a prosthetically driven approach with the aid of digitally constructed surgical guides.
* Provisional Loading:** Temporary restorations are loaded immediately after the implants are inserted and worn throughout the healing phase.
* Final Restoration:** After three months of healing, the final fixed partial denture-made of PEEK and veneered with "Visio-lign" composite-is inserted.
* Digital Workflow:** The design and fabrication of the restoration follow a fully digital CAD/CAM workflow.
* Monitoring:** The health of the bone around the implants is measured using digital X-rays at 6 and 12 months Receives: Procedure: PEEK (Polyetheretherketone) screw-retained implant restoration veneered with composite |
What is being measured
The primary outcome is the main question the study is designed to answer.
Margina Bone Loss
Method: The marginal bone height level is radiographically assessed using Digital Subtraction Radiography with the DIGORA system.
Technique: Researchers utilize a long paralleling technique to measure bone height in millimeters from the mesial and distal aspects of the implants.
Standardization: To ensure consistency across different time points, a customized occlusal bite index (made of hard acrylic attached to a film holder) is used to standardize the film placement and the angle of the X-ray cone.
Measured: the assessments are conducted at the following intervals: Baseline (T0): Immediately after the placement of the implants. 6 Months (T4): Six months after the initial implant placement. 12 Months (T5): One year after the initial implant placement
