*Implant components

*Implant Types*Subperiosteal*Transosteal*Endosteal plate form(blade vent) Root form

1- Difficulty of preparing precision slots for blade placement compared to placing holes.

2-Accurately for root-form implants 3-The disastrously large circumferential area of the jaw that can be affected when a blade fails.

Plate form

*Material Ti or Ti alloy with or without HA*Threaded or non threaded*sand blasted or acid etched to roughen the surface*Tapered or Straight

Root form

*Principles of Implant Location

*Osseointegration

*Osseointegration refers to a direct structural and functional connection

between ordered, living bone and the surface of a load-carrying implant.

Currently, an implant is considered as osseointegrated when there is no

progressive relative movement between the implant and the bone with which it

has direct contact.

Comparison of tooth root and implant

Anatomic Limitations•1.0 mm of bone on both the lingual and the facialaspect of the implant. •There should also be adequate space between adjacent implants. About 3.0 mm - to ensure bone viability - to allow adequate oral hygiene

*Anterior Maxilla Nasal cavity 1mm Incisive Foramen*Posterior maxilla The bone of the posterior maxilla is less dense than

that of the posterior mandible. Maxillary sinus 1mm*Anterior mandible At least 5mm anterior to the mental foramen*Posterior mandible 2.0-mm margin from the apex of the implant to the

superior aspect of the inferior alveolar canal.

* Implant body* Cover screw* Healing abutment * Abutment* Impression post* Laboratory analogs*Waxing sleeves

*Clinical implant components

Types of abuments

*Implant body

*Cover screw

* Closed tray * Open tray

*Type of impression

*Analogs

*Waxing sleevesThe waxing sleeve simplifies the work of the laboratory technician. It is designed to fit over the titanium post and core and can easily be modified, shaped, and waxed-to to create an ideal metal support for a fixed prosthesis.
