Q

Fixture/ Implant: Macro-Geometry -
Parallel and Tapered

A

Greatest surface area and stress distribution = parallel
Indicated for limited apical space (anatomical constraints) = tapered

Q

Fixture/ Implant: Micro-Geometry -
Smooth
Minimally rough
Moderately rough
Rough

A

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

Study These Flashcards
A

Bone level implant type

22
Q

Fixture/ Implant: Implant type -
More technique sensitive to restore

Study These Flashcards
A

Bone level implant type

23
Q

Fixture/ Implant: width -
Narrow (<3.5 mm)

Study These Flashcards
A

3.5-2.9-3.3
Incisors lower arch, laterals upper arch or edentulous

24
Q

Fixture/ Implant: width -
Regular (4-6mm)

Study These Flashcards
A

4.1
Incisors upper arch, canines, premolars or edentulous
4.8
Pre-molars and molars

25
Fixture/ Implant: width - Wide (>6 mm)
6.5 Molars lower arch
26
Fixture/ Implant: Connection - Screw loosening due to lateral forces
External connection
27
Fixture/ Implant: Connection - Internal chamber to which the abutment can engage. Improves abutment stability, fit, and seal performance
Internal connection
28
Abutments: Submerged healing Avoid soft tissue to proliferate in the implant connection Color-coded for easy identification
cover screw (look at pic)
29
Abutments: Cover screw has different heights. It is removed at the __ and never __
2nd stage surgery (uncover) NEVER torqued
30
Abutments: Transmucosal (tapered, conical, ovid) Not useable to make the final impression Help in initial tissue shaping
Healing abutment (Look at pic)
31
Abutments: Placing a larger healing abutment helps the
restorative dentist (soft tissue management)
32
Maintains an opening through the soft tissue during treatment, allowing easy access to the implant
Healing abutment
33
Abutments: Custom healing abutment
Can add composite for a custom healing abutment Comes in different heights and widths NEVER torques (look at pic)
34
Abutments: Prosthetic abutments can be __ or __
prefabricated or custom
35
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
36
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
37
Analogs/ Replica =
Abutment Fixture/ Implant
38
Analogs/ Replica: Abutment-level impressions = Implant-level impressions =
Abutment Fixture/ Implant
39
Impression coping can be __ or __
Open-tray or closed-tray
40
Requires modification of the tray Color coded and different sizes (short, long) Allows for verification jig (splinting for multiple implants)
Open tray
41
Does not require modification of the tray easier for limited opening Sometimes easier in the posterior
Closed tray
42
Connection armamentaria =
screwdriver and torque wrench
43
Connection armamentaria Screwdriver
Look at pics
44
Connection armamentaria Torque wrench
Torque to 15 Ncm (provisional) or 35 Ncm (final restoration) ALWAYS have faculty show you prior to using
45
Connection armamentaria Torque wrench: Arrow towards the numbers = Arrow away from the numbers = Only touch the __ when torquing
torquing un torquing tear drop
