3D Model Simulation andPatient Surgery in Guided Bone Regeneration

The anterior maxilla has traditionally been a challenge when it comes to successfully placing dental implants.This is due to a combination of poor bone quality, ridge atrophy and bone resorption following extraction.Many techniques are available today for the experienced surgeon to rebuild lost bone, including guided bone regeneration (GBR).Despite GBR being a predictable procedure, complications can and do arise that may compromise outcomes.The most frequent of these include membrane exposure, fenestration/dehiscence, infection, graft particle leakage, collapse of the grafted site and excessive bleeding.However, careful pre-surgical planning is crucial and will reduce risk and incidence of complications.Cone Beam Computed Tomography (CBCT) provides greater detail and has become a commonly used diagnostic tool for implant treatment planning.Patient 3D printed models can be used to gain insight and become familiar with a patient's exact anatomy prior to the surgical procedure.Using such models can aid in reducing surgical time, limiting the amount of soft tissue manipulation, familiarizing the surgeon with the patient's specifi c anatomy, therefore reducing the risk of intra-operative complications, and decreasing the potential for error.The purpose of this article is to report on the use of a 3D printed model to familiarize with the anatomy of the patient prior to the surgery to plan and avoid possible complications.
