Local risk factors
for Perio
- Definition of 'local risk factors'
- Factors associated with the teeth and
supporting tissues that may initiate or
predispose to periodontal disease
- Anatomical risk factors
- Trauma from occlusion
- Traumatic incisor
relationships
- Overbite
- Akerly classification
for overbite
- I = The lower incisors occlude with
the palatal mucosa causing mucosal
trauma away from the patatal
gingival margin
- II = Lower incisors are
traumatising the palatal gingiva of
the upper incisor
- III = Trauma to the upper
palatal gingiva & trauma to
lower labial gingiva
- AKA attrition
- Also known as complete overbite
- Class II DIv
2
- Traumatic occlusal
interferences and contacts
- Primary occlusal
trauma
- Pt who are
periodontally healthy
- Secondary Occlusal
trauma
- Pt's who are already
periodontally involved
- Premature contacts
- Anatomical
- Furcations
- Treatment
- Surgical options
- Furcationplasty
- Not really done
now
- RSI with flap surgery for access
- Tunnel preparation
- Not really done
now
- Mandibular
molars
- Guided tissue regeneration (GTR)
- Best in Class II
Furcations
- Allows new bone, new
periodontal ligament
and new cementum to
colonise.
- Excludes the undesirable cells
from the would so that desirable
tissue can repopulate the wound
space.
- Make flap, RSD, place
a membrane in the
pocket made up of
collagen which will
enable a blood clot to
form which causes
healing
- root resection/hemisection
- Non-surgical options
- Plaque control & Calculus removal
- RSD
- Enamel pearls
- Localised deep pocket
- PDL cant attach to cementum
- Gingival recession
- Tooth-arch relationships
- Root morphology
- Iotrogenic risk
factors
- Trauma from occlusion
- Traumatic occlusal
interferences and
contacts
- Premature contacts
- Poor restorations
- After orthodontist
- Overhanging restorations
- Crown margins
- Poor margins can be
plaque retentive
- Orthodontist appliances
