With reliable functional and esthetic results, dental
rehabilitation with implants has been widely accepted
by doctors and patients in the past several decades.
However, the prerequisite for achieving a long-term
implant-supported functional restoration is the presence
of adequate residual bone volume for placement of the

when using osseointegrated implants in dental rehabilitation,
clinicians frequently confront anatomic variations
