2/6 Flashcards by Abigail Cook

B-L width relevance to implant diameter?

B-L width 2mm MORE than implant diameter

2 mm bone on either side of B and L

closed trey impression basics

closed tray impression coping

material syringed

coping stays in mouth with closed tray
- then unscrew and put this into lab analog

need to know diameter of implant and brand
- lab analog needs to match

put back into the impression

positioning jig

needed when custom abutment comes back

- helps make sure abutment is in right orientation

what implant system to use?

• Published paper on safety and efficacy  JOURNAL
o 5+ years, independent research
• Internationally available!
o Want to be able to accommodate patients who travel/move
• Established
• Has ALL components you need  fixed remo, prefabricated abutments, screw retained, cement retained

one of first questions to ask when thinking about what system to use

○ You need to have research from an independent university research about safety and efficacy
○ Five years published
○ That is the only valid pulibilcation that you can accept

when topography is similar to bone?

it is easier for osseonitegration to happen

like acid etch
sand blasting

popular systems

Nobel biocare, 3i, Zimmer, Straumann

● Nobel biocare had26% of market in 2002
● 3i

helaing abutment size

size of implant going to restore

trichannel is

nobel biocare

neck design

o Shape (parallel, taper, concaved taper)
o Length (0-3mm)
o Texture (machined, micro-groove, HA-coated)
 Sand-blasting, like microscopic bombs
 Acid etched  topography becomes similar to bone

autografts

same person
examples
- ramus, chin, hip

angle of mandible - adds height and width

allografts

same species

- example = demineralized freeze / dried bone

xenograft

different species

- bovine mineral material like BioOss

alloplast

synthetic bone graftin materials

- tricalcium phosphate, HAP, coral

D1 BONE

MOST COMPACT - not enough marrow to supprt implant - 6% in anterior mandible 3% in posterior mandible

find d2 bone more

mandible 66% on anterior mandible and 50% on posterior mandible as compared to 25% on anterior maxilla and 10% on posterior maxilla

find d3 bone more where

on maxilla 65% on anterior maxilla and 50% on posterior maxilla as compared to 25% on anterior mandible and 46% on posterior mandible

d4 bone?

not dense enough 10% in anterior maxilla and 40% posterior maxilla 3% on anterior mandible and 1% on posterior mandible

we want what type of bone

2 and 3 find 2 more on mandble and 3 more on maxilla

lit review by goodman in terms of endo tx, extraction and implant crown, FPD, or extraction without tooth replacement

A systematic review by Goodacre was conducted to compare the outcomes of endodontic care and restoration compared to extraction and placement of implant supported crowns (ISC), fixed partial dentures(FPD), or extraction without tooth replacement. Success rates for ISCs were found to be higher than for RCTs and FPDs respectively.

study done regarding implants in cirriculum

more onvolvment in predoc = more involvment placing implants in clinical practice

things to consider in single tooth replacement

perio health crown lengthening needed? positin? root length? - like canine - long root vs blunted root cost of CLP and endo cast post core or implant

considr in mutli-rooted teeth

``` position crown lengthening? furcation involvment? - like where would you be after crown lengthening cost perio health ```

implant vs bridge consideration list!!!*

patient desire! anatomical considerations - nerve, root proximity, lack of bone abutment distance abutment conditions - - broken down adjacent teeth? or teeth with large fillings? - could place an implant and two crown OR bridge occlusion cost

impression to lab for

positioning jig for abutments created

splinting - general

forces are divided between two implants lateral forces are spread vs just going to one implant

3 implants next to each other? splint?

only time this would fail is if we ended up with a posterior cantilever but other case - if one fails - we can take out bad implant and fill in with acrylic and use other two as support

longer 4 unit cantilever make sure have

parallel walls and a long bevel - wih mesial cantilever over posterior need strong contact between cantilever and tooth - prevent pocelain from fracturing

anterior case he showed us with missing incisor on mandibular anterior tx options

1. ortho 2. long span bridge 3. maryland bridge 4. three unit bridge 4. implant 5. removable 6. root canal and post and core and corwn • If you take a tooth out, you need to make sure there is something to keep the papilla o Tissue follows bone and this will flatten out over time if there is nothing to hold this in place
