What is the primary function of an abutment in implant prosthetics?
Answer: To connect the implant fixture to the prosthetic crown
The abutment serves as the connector between the implant fixture and the prosthetic crown or restoration.
Which type of prosthetic restoration is supported by implants yet can be removed by the patient for cleaning?
Answer: Implant-supported overdenture
An implant-supported overdenture is a removable prosthesis that snaps onto implant attachments and can be removed by the patient for cleaning.
What is the anatomical space called that forms between the implant abutment and the surrounding soft tissue, similar to a gingival sulcus?
Answer: Peri-implant sulcus
The peri-implant sulcus is the shallow crevice around the implant abutment created by the surrounding soft tissue attachment.
Which retention method for implant crowns uses a screw passing through the restoration to secure it directly to the abutment?
Answer: Screw-retained
Screw-retained crowns are secured to the implant or abutment using a retention screw that passes through the occlusal surface of the restoration.
What is the recommended torque range for tightening most implant abutment screws according to manufacturer guidelines?
Answer: 25–35 Ncm
Most implant abutment screws are tightened to 25–35 Ncm as specified by manufacturers to prevent loosening while avoiding screw fracture.
What material is typically used to seal the screw access hole in a screw-retained implant crown after final placement?
Answer: Composite resin or PTFE tape
The screw access hole in a screw-retained crown is typically sealed with composite resin or PTFE (Teflon) tape to allow future access while protecting the retention screw.
