Root-form, endosseous dental implants for insertion into an opening in the jawbone of a patient include a body portion, a neck and/or neck/abutment portion above the body portion, and an internally-threaded shaft; a separate optional implant extender for placement atop the implant with a top surface that mimics the top surface of the implant, and includes a longitudinal passage that receives a healing screw, and a healing screw with a threaded distal end portion to pass through the longitudinal passage, engage the internal threads of the implant and hold the extender to the implant, or to cover the opening to the internally threaded shaft of the implant where the optional extender is omitted.
