ALL CLINICAL CASES
Case:
She is 24years old. Her chief complain is to make over her smile as favorite Japanese actor.
Diagnostic findings
• Extraoral and facial findings
Concave facial profile
Increased lower facial height
Slight prognathic and mandible
2. TMJ and mandibular range of motion
R: Temporo mandibular Antero-lateral displacement without reduction
L: Temporo mandibular Antero-lateral displacement with reduction
Mandibular range of motion is limited
3. Intraoral findings
Dental
Many caries tooth
Steep posterior occlusal plane
Anterior open bite
Class3 malocclusion
Periodontal
Generalized mild to moderate gingival inflammations
Bleeding on probing
Disproportionate levels of marginal gingiva
4. Occlusal notes
Class3 relationship
Horizontal overlap (overjet): 0mm
Posterior reverse articulation( cross bite) of teeth: #45,#46,#47
Anterior open occlusal relationship; no anterior guidance
Centric relation is not coincide MIP
5. Radiographic findings
Need root canal treatment:#17,#16,#15,#12,#27,#46
Caries; #14,#11,#21,#22,#25,#26,#36,#45,#47
Diagnosis
Class3 malocclusion with open bite
Goal/objectives of treatment
Face
Improve facial balance/profile
Reduce lower facial height
Reduce prominence of chin
Smile
Improve appearance of teeth with respect to shape, size, color, and position
Balance levels of maxillary marginal gingiva
Improve alignment of the teeth
Dentition
Balance levels of maxillary and mandibular marginal gingiva
Establish normal morphology of clinical crowns with appropriate dimensions
Establish adequate tooth length to facilitate retention of restorations and resistance to
displacement
Eliminate caries lesions
Correct malocclusion of teeth and associated dental and skeletal findings
Align teeth and correct rotations
Establish Class1 relationship, at least anteriorly
Establish optimal horizontal and vertical overlap of teeth-eliminate anterior open bite
relationship
Level occlusal and incisal planes
Establish symmetric dental arch
Eliminate arch length deficiencies and associated crowding of teeth
Establish appropriate spacing for optimal restoration of teeth
Coordinate dental Arches
Restore affected teeth to improve occlusion, function,appearance,stability of tooth position
and ability of patient to maintain health and supporting structures
Active Clinical Treatment
Phase Ⅰ: Initial treatment
Phase Ⅱ: Surgical crown lengthening
Phase Ⅲ:Orthodontic treatment
Phase Ⅳ:Definitive restorative treatment
Phase Ⅴ:Maintenance
