Real-Time Dynamic Navigation System for the Precise Quad-Zygomatic Implant Placement in a Patient with a Severely Atrophic Maxilla
Published on: October 18, 2021
A direct metal laser sintering (DMLS) root analogue implant placed in the anterior maxilla. Case report
Background:
Modern cone beam computed tomography (CBCT) acquisition and three-dimensional (3D) image processing, combined with direct metal laser sintering (DMLS), allows custom-made, root-analogue implants (RAIs).
Purpose:
To demonstrate how DMLS permits customized titanium RAI production, with immediate insertion and restoration in a fresh extraction socket of the anterior maxilla.
Materials And Methods:
A titanium RAI perfect copy of the radicular unit needed for replacement was created by customized DMLS, and inserted into a fresh extraction socket of the esthetic area of the anterior maxilla.
Results:
Follow-up after 1 year: the DMLS RAI implant showed a satisfactory functional and esthetic integration, with no bone resorption or soft tissue recessions.
Conclusions:
The production of customized DMLS RAIs opens new interesting perspectives for immediate implantation.
Key Words:
Direct metal laser sintering, Root analogue implant.
