thin scalloped

thick flat

thick scalloped

Mucogingival Deformities and Conditions

• periodontal biotypes:

• t_____ s______: thin tissue and bone, slender triangular teeth, subtle scalloped tissue

• t_____ f_____: prominent tissue and bone thickness, square-shaped teeth, broad zone of keratinized tissue

• t______ s______: thick fibrotic tissue, triangular teeth, slender shaped, pronounced gingival scalloping, lack of keratinized tissue

aberrant frenum

a_____ f______: unusual or strong frenum attachment/ frenum attachment is in the wrong place or is pulling too hard

normal (with recession)

what mucogingival condition is this?

keratinized tissue

very thin keratinization

thick scalloped

(not wide zone of attachment)

Describe this tissue type

• there is lack of k____ t_____

• v___ t_____ k_______

• biotype: t____ s______

aberrant frenum

decreased vestibular depth

narrow zone of keratinized tissue

scalloped

Describe the tissue type:

• a_______ f______

• d______ v______ d_____

• n_____ z_____ o_ k______ t_____

• likely s____ biotype: more likely disease with frenum because of thin attachment

square

thick

Describe the teeth shape and gum type:

• ______ shaped teeth

• ____ gums

triangle

thin

Describe the teeth shape and gum type:

• ______ shaped teeth

• ____ gums

• significant because bacteria can go through this tissue easily

thin

____ biotype:

• thin scalloped biotype (15% prevalent less common than other biotypes)

• distinct disparity between location of gingival margin facially and interproximally (thick point between teeth gives it a triangular shape)

• delicate and friable soft tissue

• small amount of attached gingiva

thick

____ biotype:

• thick flat biotype--more prevalent (85%)

• adequate amount of attached gingiva

• dense fibrotic soft tissue

• ideal for placing implants

thin

thin scalloped

triangular

delicate, friable

small, attached

____ biotype:

• t____ s_____ biotype (15% prevalent less common than other biotypes)

• distinct disparity between location of gingival margin facially and interproximally (thick point between teeth gives it a _______shape)

• d_____ and f_____ soft tissue

• s____ amount of a_____ gingiva

thick

thick flat

adequate, attached

dense fibrotic

square

implants

____ biotype:

• t_____ f____ biotype--more prevalent (85%)

• a______ amount of a_____ gingiva

• d_____ f_____ soft tissue

• _____ shaped teeth

• ideal for placing i______

thick, flat periodontal biotype because there are square teeth, large zone of attached gingiva, smaller embrasures, dense fibrotic gingiva

what biotype is this and why?

thin periodontal biotype due to scalloped gingiva with a narrow zone of attachment, triangular teeth, thin periodontium reveals undulating contours of the prominent roots of the teeth and bone

what biotype is this and why?

false

KNOW

• t/f: thin biotype is more prevalent/common

true

KNOW

• t/f: thick biotype is more prevalent/common

thick

Gingival Deformities

• most common is t____

thin

attached gingiva

alveolar bone

traumatic toothbrushing

recession, slowly

Gingival Deformities

• risk factors for development

• t___ biotype

• absence of a____ g____

• thickness of the a_____ b____

• trauma associated with recession most commonly from t_____ t______

• ortho can cause r____, need to move teeth s_____

frenum

frenectomy

tissue graft

pt ed

extra soft, Stillmans

What is this recession caused by and what are some treatment methods for this pt?

• caused by: ________

• treatment:

• f______

• t_____ g_____

• p__ e___

• product recommendations: e____ s____ TB, s______ TB technique

frenum

What is this recession caused by?

• hint: look at neighboring teeth for recession

MGJ

not

tissue loss

KNOW

Miller Classifications

• reasons we DON'T use this anymore

• hard to find ___

• reliability has n___ been tested

• doesn't define t____ l____ compared to Cario

1, RT1

KNOW

Cairo Classification System

• Type __ (___)

• no loss of interproximal attachment

• attachment loss only on facial or lingual--can't see CEJ on mesial or distal

• most likely from traumatic TB

2, RT2

KNOW

Cairo Classification System

• Type __ (___)

• interproximal attachment loss is LESS than or equal to the buccal/facial attachment loss

• associated with horizontal bone loss

3, RT3

KNOW

Cairo Classification System

• Type __ (___)

• recession with loss of interdental attachment

• the proximal attachment loss is greater than the buccal attachment loss

• seen with infrabony defect

• associated with vertical bone loss

Cairo recession type 1, RT1

KNOW

• what recession type is associated with traumatic toothbrushing?

Cairo recession type 2, RT2

KNOW

• what recession type is associated with horizontal bone loss?

Cairo recession type 3, RT3

KNOW

• what recession type is associated with vertical bone loss?

Cairo recession type 2 (because there is interproximal attachment loss and it is less than the facial attachment loss)

KNOW (possible question)

• facial attachment loss of 4mm and there is 3mm of interproximal attachment loss. What Cairo classification system is this?

Cairo recession type 3 (because proximal attachment loss is greater than the facial attachment loss)

KNOW (possible question)

• facial attachment loss of 6mm and there is 8mm of interproximal attachment loss. What Cairo classification system is this?

caries, enamel

Product recommendations for recession

• need to recommend something for c___ control because it is NOT protected by e_____

sensitivity

Product recommendations for recession

• need to recommend something for s_______

proxy brush

Product recommendations for recession

• need to recommend something for embrasure spaces for example a _____ _____ would be a good recommendation

finger, thumb

Product recommendations for recession

MGJ

Product recommendations for recession

• see ____ deformities with recession

frenum, attachment, 2

Product recommendations for recession
