digital workflow for adhesive ceramic restoration

interdiscipline

you work w different specialties to deliver care/tx for a pt to restore function and satisfy pts esthetic needs

principles of digital workflow come from

conventional workflow

when doing a full mouth re-construction, first, you want to start w

esthetic analysis

esthetic analysis consists of…

• tooth display at rest

• gingival display at rest

as you get older, how does the tooth display at rest change w maxillary centrals

decreases

as you get older, how does the tooth display at rest change w mandibular centrals

increases

pt preference of anterior dental esthetics, what was found in this study w tooth display at rest

3 mm was preferred → regardless of age

rank low, average, and high smile line from most to least common in the population

1. average

2. low

3. high

pt preference of anterior dental esthetics, what was found in this study w gingival display at smile

younger group (group I): liked 0 mm

older group (group II): liked -2 mm

how to eliminate a “gummy” smile

• crown lengthening

• gingivectomy

• orthognathic surgery

main purpose of implant provisional

can move the gum tissue where you want→ if you known how to do

shell technique

have the external surface done for you restoration, but need to reline the internal to adapt to your prep

functional rehabilitation is managing the _____ and ______ occlusal force

static; dynamic

when you have poured up impression of both arches, what is the order in which you will mount and how

1. maxillary → w facebow transfer

2. mandibular → use bite record in mount in centric relation

3. establish occlusion and guidance

what you can use for facebow transfer

• kinematic facebow

• earbow facebow

• Kois Dento-facial Analyser

when mounting the upper and lower arch, if you are only doing a single crown, you will mount in…

MIP

when mounting the upper and lower arch, and you are trying to establish a new occlusal scheme, you will mount in…

centric occlusion → is the most reproducible

centric relation vs centric occlusion

• CR: anterior superior relationship of the condyle → NOT related to tooth

• CO: tooth contact in CR

how to take centric relation

• leaf gauge

• lucia jig

what guidance do you have to establish after mounting the upper and lower

• anterior guidance

• condyle guidance

what is used on the articulator to accomplish guidance

custom incisal guide table

if you want to inc VDO, you need to check what 3 things

• facial esthetics

• physiological rest position

• phonetic assessment

how is freeway space found

arbitrarily subtracting 3 mm from the VDR

how is the closest speaking space measured

measuring during fricatives and sibilant sounds

how does margin width and occlusal reduction chamge from 3Y → 4Y → 5Y zirconia

minimum:

• 3Y: 1mm reduction, .6 mm margin

• 4Y: 1.2 mm reduction, .8 mm margin

• 5Y: 1.5 mm reduction, 1 mm margin

what is a multilayered zirconia block

made up of different compositions of zirconia

how this true transverse horizontal axis is calculated in the software program of the jaw tracking system is…

unknown

_________________ to asses the accuracy of these optical jaw tracking systems when recording the CR location and the condyle guidance

studies are needed
