Resource summary
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
