Summary

This trial is testing a dental implant that can be placed soon after a tooth is removed. It focuses on patients who need extractions in specific areas of their jaws. The goal is to see if this placement helps maintain bone levels and provides stable support for new teeth. This method was introduced to limit bone loss and reduce the number of surgical procedures following tooth extraction.

Who is the study for?
Adults needing a single tooth extraction and implant in the front or premolar area of their upper or lower jaw, with healthy adjacent teeth and sufficient bone for stability. Participants must be in good health, able to perform oral hygiene, not pregnant, non-heavy smokers (less than 10 cigarettes/day), without severe bruxism or TMJ issues, and committed to follow-up visits.
What is being tested?
The study compares outcomes of placing Straumann Bone Level Tapered implants immediately after tooth extraction versus delayed placement in healed sites. It's randomized and controlled across multiple centers to assess clinical performance and x-ray results.
What are the potential side effects?
Potential side effects are not explicitly listed but may include typical risks associated with dental implant surgery such as infection, swelling, pain at the implant site, bleeding, nerve damage leading to numbness or tingling sensation, and possible failure of the implant.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Immediate Placement - TestExperimental Treatment1 Intervention
Straumann Bone Level Tapered Implant - Immediate Placement - Implant is placed at the time of tooth extraction to replace a single tooth.
Group II: Delayed Placement - ControlExperimental Treatment1 Intervention
Straumann Bone Level Tapered Implant - Delayed Placement - Implant is placed after 16-18 weeks of healing to replace a single tooth.

Other Research
Dental implants, such as the Straumann® Bone Level Tapered implant, are a common treatment for tooth loss. These implants act as artificial tooth roots, providing a stable foundation for dental prosthetics like crowns, bridges, or dentures. The implant is surgically placed into the jawbone, where it undergoes osseointegration, a process where the bone fuses with the implant, ensuring stability and durability. This is crucial for tooth loss patients as it restores functionality, improves aesthetics, and prevents bone loss that can occur when teeth are missing. Immediate implantation can be done right after tooth extraction, while delayed implantation is performed after the site has healed, offering flexibility based on the patient's condition.
