Fixture/implant connection
External
Internal
Threaded
Immediate placement into extraction sockets
Increase primary stability
Increase BIC (bone implant contact)
Which implant level provide widest implant neck
Tissue
Which implant level is easier to access
Tissue
Where is tissue level implants used
In posterior teeth with thick soft tissue, when esthetics is not a concern
Which implant level is used for larger implant crowns (bone loss)
Tissue
What happens with inadequate placement with tissue level implants?
Will result in prosthetic complications
Which implant level permits development of emergence profile
Bone
Which implant level has manipulation of the soft tissue to provide an appearance of a natural tooth
Bone
What is necessary in the anterior for bone level implants
Provisionalization
Which implant level is more technique sensitive to restore
Bone
Narrow width
> 3.5 mm
Regular width
> 4 mm to > 6 mm
Wide width
> 6mm
Healing abutments 2 things
Cover screws
Transmucosal (tapered,conical, ovoid)
Cover screw characteristics
Submerged healing
Avoid soft tissue to proliferate in the implant connection
Color coded
Different heights
It is removed at the 2nd stage surgery or uncover surgery
T/F: you torque cover screws
False - NEVER torqued, can strip screw head
Transmucosal (tapered,conical, ovoid) characteristics
Maintains an opening through the soft tissue during treatment, allowing easy access to the implant
Not useable to make the final impression
Help in initial tissue shaping - can add composite for custom healing abutment
Comes in different heights and widths
Placing a larger healing abutment helps the restorative dentist (soft tissue management)
T/F: Transmucosal are torqued
False - never torqued
T/F: stocks are prefabricated abutments and cannot be modified
True
Stock characteristics
Cement retained restorations
Screw into the implant body
Less expensive and easier for the lab
Different types of stock
Straight
Angled
Anatomic
Ceramic
Custom abutments characteristics
Allow Anatomic design of the abutment
Cement retained restorations and screw retained restorations
Custom designed for final restoration
Why are custom abutments more expensive
Gold cylinder + metal allow
CAD/CAM fabricated custom abutment
Milled from titanium
Angle abutments characteristics
Correct implant angulations
Usually associated with multi unit restorations
Screw or cement retained
Different angle correction
Different heights
Precision attachments (overdentures) self aligning attachment system (locators)
Unsplinted
Resilient dual retention system
Precision attachments most common complications
Dull insert
Lost of retention over time
Dislocation of metal housing
Analogs/replica-laboratory use - abutment level
Stock
Angled
Analogs/replica-laboratory use Implant (fixture) level
Tissue level
Bone level
Open tray
Require modification of the tray
Need to make sure impression material does not get locked into the access
Allows for verification jig (splinting of multiple implants)
Short vs long open tray
Short - posterior
Long - anterior
Engaging vs non engaging open tray
Engaging - single unit
Non-engaging - multi unit
Closed tray
Does not require modification of the tray
Easier for limited opening
Sometimes easier in the posterior
Torque wrench
Torque to 35 Ncm (final rest)
Always have faculty show you prior to using
Only touch the tear drop when torquing
Arrow toward you torque wrench
Torquing
Arrow away from you torque wrench
Un torquing
