Abstract
|
|
|
|
This article describes the treatment provided to a patient exhibiting severely atrophic mandibular posterior region complaining of the paresthesia of both alveolar ridges near the mental foramen. Severe atrophy of the alveolar ridge disabled any removable denture treatment to have sufficient retention and stability without irritating mental foramen area. Implant-supported fixed prosthesis was planned utilizing All-on-Four treatment concept. CAD/CAM abutment was customized for distally tilted implants and implant-supported fixed prosthesis was successfully fabricated.
