Fixture/ Implant: Material-
Both Materials are
Biocompatible (Titanium and Zirconia)
Fixture/ Implant: Material -
Function without causing damage to __
surrounding tissues
Fixture/ Implant: Material -
Resist forces during
function/ parafunction and cyclic loading
Fixture/ Implant: Material -
Resistance to __ and __
Corrosion and wear
Fixture/ Implant: Material -
Modulus of elasticity close to the
surrounding bone
Fixture/ Implant: Macro-Geometry -
Threaded
Immediate placement into extraction sockets
Increase primary stability
Increase BIC (bone implant contact)
Fixture/ Implant: Macro-Geometry -
Parallel and Tapered
Greatest surface area and stress distribution
Indicated for limited apical space (anatomical constraints)
Fixture/ Implant: Micro-Geometry -
Smooth
Minimally rough
Moderately rough
Rough
Smooth - bone anchorage (too smooth for osseointegration)
Minimally rough- weaker bone integration
Moderately rough- stronger bone responses (most implants today)
Rough - increased incidence of peri-implantitis
Fixture/ Implant: Implant type -
Tissue level
bone level
look at pics
Fixture/ Implant: Implant type -
Provide wider implant neck
Preferred in posterior with thick soft tissue
Tissue level Implant type
Fixture/ Implant: Implant type -
Esthetic is not a concern
Tissue level implant type
Fixture/ Implant: Implant type -
Used for larger implant crowns
Inadequate placement will result in prosthetic complication
Tissue level implant type
Fixture/ Implant: Implant type -
Permit development of emergence profile
manipulation of soft tissue- appearance of a natural tooth
Bone level implant type
Fixture/ Implant: Implant type -
Anterior teeth - provisionalization
Bone level implant type
Fixture/ Implant: Implant type -
More technique sensitive to restore
Bone level implant type
Fixture/ Implant: width -
Narrow (<3.5 mm)
3.5-2.9-3.3
Incisors lower arch, laterals upper arch or edentulous
Fixture/ Implant: width -
Regular (4-6mm)
4.1
Incisors upper arch, canines, premolars or edentulous
4.8
Pre-molars and molars
Fixture/ Implant: width -
Wide (>6 mm)
6.5
Molars lower arch
Fixture/ Implant: Connection -
Screw loosening due to lateral forces
External connection
Fixture/ Implant: Connection -
Internal chamber to which the abutment can engage. Improves abutment stability, fit, and seal performance
Internal connection
Abutments:
Submerged healing
Avoid soft tissue to proliferate in the implant connection
Color-coded for easy identification
cover screw (look at pic)
Abutments:
Cover screw has different heights. It is removed at the __ and never __
2nd stage surgery (uncover)
NEVER torqued
Abutments:
Transmucosal (tapered, conical, ovid)
Not useable to make the final impression
Help in initial tissue shaping
Healing abutment (Look at pic)
Abutments:
Placing a larger healing abutment helps the
restorative dentist (soft tissue management)
Maintains an opening through the soft tissue during treatment, allowing easy access to the implant
Healing abutment
Abutments:
Custom healing abutment
Can add composite for a custom healing abutment
Comes in different heights and widths
NEVER torques
(look at pic)
Abutments:
Prosthetic abutments can be __ or __
prefabricated or custom
Abutments: Prosthetic Abutments -
IT cannot be modified
Cement-retained restorations
Screw into the implant body
Less expensive and easier for the lab
Straight, Angled, Anatomic , Ceramic
Prefabricated
Abutments: Prosthetic Abutments -
Allow anatomic design of the abutment
Cement-retained restorations and screw retained restorations
Custom designed for final restoration
More expensive, Gold cylinder + metal alloy
CAD/CAM fabricated: milled from titanium
Custom
Analogs/ Replica =
Abutment
Fixture/ Implant
Analogs/ Replica:
Abutment-level impressions =
Implant-level impressions =
Abutment
Fixture/ Implant
Impression coping can be __ or __
Open-tray or closed-tray
Requires modification of the tray
Color coded and different sizes (short, long)
Allows for verification jig (splinting for multiple implants)
Open tray
Does not require modification of the tray
easier for limited opening
Sometimes easier in the posterior
Closed tray
Connection armamentaria =
screwdriver and torque wrench
Connection armamentaria
Screwdriver
Look at pics
Connection armamentaria
Torque wrench
Torque to 15 Ncm (provisional) or 35 Ncm (final restoration)
ALWAYS have faculty show you prior to using
Connection armamentaria
Torque wrench:
Arrow towards the numbers =
Arrow away from the numbers =
Only touch the __ when torquing
torquing
un torquing
tear drop
