    • The spectrum of surgeries Distraction osteogenesis www.indiandentalacademy.com
    • DIAGNOSIS a. Deciding the need for Surgery b. Deciding where the fault lies. c. Quantifying the extent of the fault www.indiandentalacademy.com
    • Deciding the need for surgery: a. Congenital or developmental craniofacial anomalies. b. Abnormal jaw growth causing marked visible facial disfigurement. c. Standard deviation as the yardstick www.indiandentalacademy.com
    • Deciding the need for surgery: d. Orthognathic surgery in most instances is elective. Patient’s opinion plays a decisive role. www.indiandentalacademy.com
    • Deciding the need for surgery: Excess mandibular growth is considered more obnoxious in our society. www.indiandentalacademy.com
    • Deciding the need for surgery: Persons with mild prognathism often seek treatment, while those with moderate mandibular deficiency may refuse surgical correction. www.indiandentalacademy.com
    • Deciding the need for surgery: e. Age considerations. www.indiandentalacademy.com
    • Deciding the need for surgery: f. Patient’s self image. www.indiandentalacademy.com
    • How to locate the fault? • History • Clinical examination • Study models • Photographs • radiographs www.indiandentalacademy.com
    • The advantages and shortcomings of both orthodontics and cephalometrics should be thoroughly understood. www.indiandentalacademy.com
    • Clinical examination a. Visual esthetic appraisal . b. Functional analysis. www.indiandentalacademy.com
    • Visual Esthetic Appraisal Relationship of facial structures with respect to their balance, symmetry, and proportions in all the three planes of space. www.indiandentalacademy.com
    • Visual Esthetic Appraisal- Frontal 1. Assessment of facial proportions. www.indiandentalacademy.com
    • Visual Esthetic Appraisal - Frontal 2. Facial Symmetry www.indiandentalacademy.com
    • Visual Esthetic Appraisal - Frontal 3. Canting of bilateral structues, specially the lips and the dentition 4.Lip Competence, exposure of upper incisors www.indiandentalacademy.com
    • Visual Esthetic Appraisal - Profile 1. Assessment of angles such as the facial angle of convexity, nasolabial angle, etc. www.indiandentalacademy.com
    • Visual Esthetic Appraisal - Profile 2. Lips in relation to various esthetic lines www.indiandentalacademy.com
    • Visual Esthetic Appraisal - Profile 3.Perpendicular distance subnasale and the chin. 4. Cheek – Bone contour. www.indiandentalacademy.com between the
    • Cephalometric Analysis Precautions while taking cephalograms 1. Condyles properly seated in the fossae. 2. Lips fully relaxed. 3. Recording in the ‘Natural Head Position’ www.indiandentalacademy.com
    • Cephalometric Analysis Precautions while doing analysis 1. Use of normative values not very appropriate, since they cannot be accurately applied to different ethnic groups, males and females, persons with varying builds, etc. www.indiandentalacademy.com
    • Cephalometric Analysis Precautions while doing analysis 2. Norms based on hard tissues alone also not appropriate due to the varying thickness of the soft tissues. www.indiandentalacademy.com
    • Cephalometric Analysis Precautions while doing analysis 3. It is better to consider as many measurements related to a particular structure. For ex: To evaluate the maxillomandibular relationship, measurements such as LNAPog, Wits, projections of points A and B on FH and palatal plane etc. alongwith the customary LANB www.indiandentalacademy.com
    • Cephalometric Analysis Precautions while doing analysis 4. Instead of relying on absolute linear measurements, projected values are more meaningful. www.indiandentalacademy.com
    • Cephalometric Analysis Precautions while doing analysis a. Size b. Placement c. Orientation www.indiandentalacademy.com
    • Cephalometric Analysis Precautions while doing analysis 6. Effect of vertical displacements on the sagittal relationship must be taken into account. www.indiandentalacademy.com
    • Cephalometric Analysis Useful readings - Sagittal Maxilla: L SNA, A perpendicular to N perp.on the true horizontal, Size of maxilla in relation to the SN length, placement of its posterior limit with respect to sella. www.indiandentalacademy.com
    • Cephalometric Analysis Useful readings - Sagittal Mandible: L SNB, B perpendicular to N perp.on the true horizontal, Size of corpus in relation to the SN length, ratio of ramus to corpus angle, placement of condyles, chin placement with respect to point B and Down’s facial angle. www.indiandentalacademy.com
    • Cephalometric Analysis Useful readings - Vertical a) Jarabak ratio b) Mandibular plane wrt SN and FH c) Linear measurements of the incisors to their corresponding jaw bases www.indiandentalacademy.com
    • Cephalometric Analysis Useful readings - Vertical d) Basal plane angle. e) Maxillary inclination angle f) PNS-Ethmoid point and ANS-Nasion. www.indiandentalacademy.com
    • Cephalometric Analysis Transverse dimension Grummon’s analysis is a useful analysis to assess transverse dysplasia. Normative data for the Indian population is being worked out in our institution. www.indiandentalacademy.com
    • Quantification of the fault This step involves the determination of the precise magnitude of surgical alteration of the jaw bases in a 3-dimensional perspective. Quantification Clinical exam Cephalometrics www.indiandentalacademy.com
    • Quantification of the fault Cephalometric Assessment a) Comparison with normative values b) Assessment using certain established ratios c) Surgical VTO www.indiandentalacademy.com
    • Quantification of the fault Cephalometric Assessment a) Comparison with normative values. Burstone and Legan’s analysis www.indiandentalacademy.com
    • Quantification of the fault Cephalometric Assessment Drawbacks of Burstone and Legan’s analysis: 1) Data was derived from a small sample belonging to the Caucasian population. 2) The ‘surrogate’ horizontal plane may give erroneous inferences. 3) Mean values applicable to the average size individuals only. www.indiandentalacademy.com
    • Quantification of the fault Cephalometric Assessment B) Useful ratios: 1) SN: Maxilla: Mandible = 20:14:21 2)Corpus:Ramus = 7:5 3) Middle face : Lower face = 45 % : 55% 4) Postr : Antr face height(Jarabak)=62– 64% 5) Nasal : Labial = 1:4( Nasolabial angle ) www.indiandentalacademy.com
    • Surgical VTO Softwares 1) Dentofacial Planner 2) Vistadent www.indiandentalacademy.com
    • Pre-Surgical Orthodontics A. Decompensating the incisor positions www.indiandentalacademy.com
    • Pre-Surgical Orthodontics B. Alignment of teeth by decrowding. Extraction pattern differs from that in camouflage. www.indiandentalacademy.com
    • Pre-Surgical Orthodontics C. Incisor intrusion done pre-surgically if an increase in the anterior face height is not desirable www.indiandentalacademy.com
    • Pre-Surgical Orthodontics D. Arch forms are corrected so that the arches are compatible with each other when surgically repositioned. www.indiandentalacademy.com
    • Pre-Surgical Orthodontics E. In case of segmental procedures, apices of teeth on either side of the cut are divergent or parallel. F. Extraction spaces not closed completely. www.indiandentalacademy.com
    • Pre-Surgical Orthodontics Appliance Selection 1) Edgewise ( Standard or Pre-adjusted ) 2) Tip-edge 3) Begg appliance ( Good quality brackets ) www.indiandentalacademy.com
    • Pre-Surgical Orthodontics Other Considerations A. Third molar extractions B. Stabilizing wires C. Model surgery and splint preparation www.indiandentalacademy.com
    • Post-Surgical Orthodontics Correction of minor deficiencies can be tried immediately after the surgery using elastic forces. Eg: Uneven midlines, Minor canting of occlusal plane www.indiandentalacademy.com
    • Post-Surgical Orthodontics a) Closure of remaining spaces b) Acheivement of proper interdigitation c) Finishing and detailing to functional occlusal criteria. www.indiandentalacademy.com satisfy the
