Question 1. Classify surgical orthodontics. Discuss minor surgical orthodontic procedures.
Answer.
Surgical Orthodontic Procedure
Minor Procedure:
- Extractions
- Therapeutic
- Serial
- Carious teeth
- Malformed teeth
- Impacted teeth
- Supernumerary teeth
- Surgical uncovering of teeth
- Frenectomy
- Pericision
- Transplantation of teeth
- Corticotomy
Major procedures:
- Orthodontic surgeries
- Cosmetic surgeries
- Surgical corrections of clefts
- Surgical RME
Minor Surgical Procedures:
Extraction:
- Therapeutic extraction
- To gain space
- Should be atraumatic
- Surgical extraction
- Removal of some deciduous teeth followed by specific permanent
- Done during mixed dentition period
- In severe arch-length deficient
- Supernumerary teeth
- It leads to malocclusion or development of cyst
- Thus, needs to be extracted
Surgical Uncovering of Impacted Teeth:
- Impacted teeth cause deflection of teeth
- Common – Maxillary permanent canine
- Cause – Arch length deficiency, Mucosal/bony barriers
- These barriers are removed to allow the eruption of impacted teeth
Frenectomy:
- Abnormal labial frenum causes mid-line diastema
- Frenum is excised along with attached fibrous tissue
- Undermining of the mucosa of the lip is done
Corticotomy:
Indication of Corticotomy:
- Proclination with spacing
The procedure of Corticotomy:
Precision:
Synonym – Circumferential Supra-crystal Fibrotomy [CSF]
- It is the procedure to counter the relapse tendency of stretched gingival fibres
Cause of Relapse: Failure of adaptation of transeptal and alveolar crystal group of gingival fibres to the new tooth position
The procedure of Relapse:
