adhesive partial coverage ceramic restorations

ceramic veneer

a thin bonded ceramic restoration that restores the facial, incisal, and part of the proximal surfaces of teeth requiring esthetic restoration

success of veneers is based on what 3 things

1. pre-operative phase

2. operative phase

3. post-operative phase

of the three steps involved in the success of veneers, which is most important

1. pre-operative phase

2. operative phase

3. post-operative phase

they are all equally important and determine success

what 2 things go into the pre-operative phase in determining the success of veneers

• proper tx planning

• proper selection of ceramics

what 2 things go into the operative phase in determining the success of veneers

• proper preparation of teeth

• proper selection of the material and methods (BONDING) of cementation

indication for veneers

• modify tooth color

• modify tooth shape/length

• close diastema

• correct mild misaligned teeth

if someone wants to correct tooth color, you want to start conservative w _______ rather than jumping to veneers

bleaching/whitening teeth

veneers can be done to modify tooth color that have been caused by… (3)

• endo tx

• tetracycline discoloration

• to enhance existing tooth color

veneers can be done to modify tooth shape/length that have been caused by… (3)

• congenital malformation

• fx teeth

• tooth wear

contraindications for veneers

• pronounced enamel defects

• severe malformations

• severe malalignment

• poor oral hygiene

why is pronounced enamel defects a contraindication for veneers

no enamel → bad for bonding procedures

in the pre-operative tx phase, esthetic analysis should be done, what does this include

• gingival display at smile

• tooth display at rest

3 kinds of gingival display at smile

• low smile

• average smile

• high smile

what shows in a low smile

• see no gums

• display < 75% of anterior teeth

what shows in a average smile

• reveal interproximal gingival only → papilla

• reveal 75-100% of anterior teeth

what shows in a high smile

• reveal and contiguous band of gingiva

• reveal the total cervico-incisal length of the maxillary anterior teeth

rank low, average, and high smile from most to least prevalence including the % of population

1. average smile 68.94%

2. low smile 20.48%

3. high smile 10.57%

gingival display at smile

high smile

as age increases, how does tooth display at rest change in maxillary centrals

will decrease

as age increases, how does tooth display at rest change in mandibular centrals

will increase

most conservative tx option for replacing maxillary laterals

implants

options for veneer material

• feldspathic porcelain

• pressable ceramics

• milled ceramics

techniques for feldspathic porcelain

• platinum foil technique

• refractory die technique

materials under pressable ceramics

• leucite reinforced glass (IPS empress)

• lithium disilicate glass (IPS e.max press)
