Dental Implant - Parts of Implant

 PARTS  OF  IMPLANT  :

 1. Implant body for Fixture

                It is the component that is placed with in the bone during first stage of surgery.

 2. Healing screw

                During the healing phase this screw is normally placed in the superior surface of body.

     Function: Prevents the growth of the tissue over the edge of  the implant.

 3. Healing caps:

                   Are dome shaped trans-epithelial attachments placed over the sealing screw after the second stage of surgery & before insertion of prosthesis.

              Also called Permucosal extension or Gingival former.

 4.Abutments

                  part of implant which resembles a prepared tooth & supports &/or retains the prosthesis or implant Superstructure.

          Three types – 1. for screw retention

                                    2. for cement retention

                                    3. for attachment

          Each of the three are further classified as  Straight or Angled abutments.

 5. Hygiene cover screw

                Placed over abt for screw retn. to prevent debris & calculus from invading the internally threaded portion of abutment during prosthesis fabrication.

 6. Impression posts ( Transfer coping )

                To position an analogue in an impression.

                Two types -  1. Implant body transfer coping

                                    2.  Abutment transfer coping

                Two basic restorative techniques used & each uses a different design transfer coping – Indirect & direct.

 7. Implant analogue

                Implant body analogue & Implant abutment analogue.

 8. Prosthetic coping

                 To fit the implant abutment for screw retention & serve as a connection between the abutment & prosthesis as superstructure

 9. Coping ( Prosthesis ) screw
