Abstract

Introduction: Modern implantology is changing direction towards the development of new implant macrodesigns that are able to provide a high level of physico-mechanical characteristics. This study examines the mechanical aspect of implants. In particular, macrodesign such as thread shape, pitch and depth.
Objectives: To evaluate clinically and radiographically fin thread design implant osseointegration and primary stability in mandibular premolar region.
Materials and methods: A clinical study was conducted on thirteen patients with missing mandibular premolar teeth. The magic fc implants with fin thread were inserted. After 3 months, final crowns were delivered. All implants were followed for 6 months. Clinically, each patient was evaluated for pain, swelling and stability of the implant. Radiographically, cone beam computed tomography (CBCT) was used for the assessment of marginal bone level and bone density.
Results:There was a significant increase in bone density from immediate postoperative to the end of the 6 months. The mean of marginal bone level from immediately post-operative to the 3rd month was significant and from immediate to 6th month was significant. One case displayed swelling in the first week and the implant was removed (failure case) due to lack of oral hygiene maintenance by the patient.
Conclusions: Magic FC implants with fin thread were a successful treatment procedure, with satisfactory clinical outcomes, and a low incidence of complications.
