One-stage surgery with a nonsubmerged implant system

Area of Science:

• Dental Implantology
• Biomaterials Science
• Prosthodontics

Background:

• Nonsubmerged implant surgery offers benefits like reduced patient trauma and cost by avoiding a second-stage uncovering procedure.
• Traditional one-piece implants present limitations in achieving optimal esthetic results due to their inability to be shortened.
• Esthetic customization is crucial for patient satisfaction in dental implant restorations.

Observation:

• A new implant design features a preattached multipurpose collar for insertion, nonsubmerged healing, and abutment connection.
• The collar can be exchanged for an esthetic abutment for submucosal margins, allowing direct connection to the implant.
• Surface modifications include roughened midsections (hydroxyapatite or titanium plasma spray), smoother acid-etched necks, and self-tapping apical ends.

Findings:

• The innovative implant design facilitates a streamlined, single-stage surgical and restorative process.
• Screw-retained, friction-fit abutments ensure high levels of prosthodontic stability and uniformity.
• The design addresses esthetic challenges associated with one-piece implants in nonsubmerged healing protocols.

Implications:

• This advancement offers a more efficient and esthetically versatile solution for dental implantology.
• The design has the potential to improve patient experience and clinical outcomes in single-stage implant procedures.
• Further research can explore long-term stability and patient-reported esthetic satisfaction with this implant system.
