About

The goal of this clinical trial is to test two different implant neck designs in 36 patients. The main question[s] it aims to answer are:

  • do triangular neck designed implants placed immediately after dental extraction have the same influence on peri-implant hard and soft tissues than regular neck designed implants at one year?
  • do triangular neck designed implants placed immediately after dental extraction have the same influence on peri-implant hard and soft tissues than regular neck designed implants at three years?

Participants that present an unrepairable tooth on the anterior upper maxilla will be asked to take a CBCT scan in order to verify the presence of the buccal bone. Once this is verified the patients will enter in the study and the day of the surgery they will be assigned to either control or test group.

  • Control group: C1 round-neck implant
  • Test groups: V3 triangular-implant neck

Researchers will compare test and control groups to see if they have the same effects on hard and soft tissues at 4 months, 1 year and 3 years.

Full description

Immediate implant placement is considered to be a technique-sensitive protocol with a variety of potential risks. The interface area between the neck of the implant and the abutment is critical; it can affect the treatment outcome, particularly mar-ginal bone loss (MBL) and soft tissue behavior. Traditionally, the implant neck is circu-lar in shape; however, a new triangular neck design has recently been introduced on the market, though advanced indications of this innovative design are still lacking.

The objective of this randomized clinical trial was to compare the clinical and radiographic outcomes obtained after immediate placement of implants and temporization of two different neck geometries: a traditional round neck (RN) and an innovative neck with a triangular shape (TN).
