Regenerative periodontal therapy Flashcards
1
Q
What are the 4 types of periodontal surgery
A
- access therapy
- resective therapy
- regenerative therapy - GTR and GBR (guided tissue/bone regeneration)
- mucogingival surgery - perio plastic surgery
2
Q
What is access therapy used for
A
gain more access to root surface in persisting pockets
3
Q
What is resective therapy
A
- remove infected soft tissue of gingiva and infected bone
4
Q
When is resective therapy used
A
- furcation resective tx e.g root resective / tunnel preparation
- gingivectomy - hyperplasia
- crown lengthening - before pros
5
Q
When is GTR and GBR used
A
- infrabony defects
- augmentation of edentulous ridge prior to implant placement
6
Q
What is mucogingival therapy used for
A
- gingival augmentation
- root coverage
- gingival preservation at ectopic tooth eruption
- preservation of ridge collapse associated with tooth extraction
7
Q
What is the aetiology of gingival recession in regards to periodontal disease
A
- bone is lost from disease process
- gingiva is inflamed
- tx reverses gingival inflammation and inflammation dies down, resulting in recession
- sign of successful tx
8
Q
What are mechanical/physical factors that can result in recession
A
- vigorous toothbrushing
- traumatic incisal relationship
- trauma from foreign bodies e.g lower lip piercings
- prominent teeth out of alignment of arch especially if thin gingival biotype
- aberrant frenal attachment - apical pull
- high frenal attachments
- iatrogenic damage - subgingival margins impinging on biological width
- ortho tx not respecting width of alveolus
9
Q
What is type 1 recession
A
- no loss of interproximal attachment
- interproximal CEJ not clinically detectable at both mesial and distal aspects
- i.e buccal/lingual recession only
10
Q
What is type 2 recession
A
- loss of interproximal attachment
- measured from interproximal CEJ to depth of interproximal sulcus is less than or equal to the buccal attachment loss
11
Q
What is type 3 recession
A
- loss of IP attachment
- amount of IP attachment loss greater than buccal attachment loss
12
Q
What types of recession are treatable
A
type 1
type 2 partially treatable
13
Q
What are the symptoms of gingival recession
A
- dentine hypersensitivity
- cervical caries
- cervical abrasion and erosion
- poor aesthetics
- loss of vitality, tooth loss
14
Q
What are the tx options for recession
A
- mointor
- use of desensitizing agents e.g vranishes and bonding agents
- composite restoration
- prosthetic crown with pink porcelain to mask - not recmomended
- removable pink gingival veneers - not good
- orthodontics - restricted cases but good result
- surgery (graft)
15
Q
What are the types of grafts that can be used in mucogingival therapy
A
- free soft tissue graft
- pedicle gingival graft
- rotational flap
- advanced flap
