Extractions in Orthodontics Indications

1-Indications: Severe dental crowding > 7mm-Tooth-arch discrepancy2-Indications: Anteroposterior relationships discrepancy. 3-Indications: unfavorable position of Tooth impaction, Dental ankylosis . 4- Indications: unaesthetic facial profile, Protrusion.5- Indications: Adult crowding with gingival recession.6- Indications: Dental Caries.7-Indications: Supernumerary teeth8- Indications: Patients not motivated and we need to shorten duration of treatment.9-Indications: Hyperdivergent facial type – vertical growth pattern.

Page 24: No Extractions Philosophy-OUSSAMA SANDID -MOHAMAD ABOUALNASER

1-Arch length- Severe Dental Crowding > 7mm

Tooth-arch discrepancy: Size of the jaw is smaller than the size of the teethDental crowding can be simply defined as the overlap of teeth caused by insufficient space within the dental arch.If the dentition is too large (Macrodontia) to fit in the dental arch without irregularity, it may be necessary to reduce the dentition size by the extraction of teeth.

Page 25: No Extractions Philosophy-OUSSAMA SANDID -MOHAMAD ABOUALNASER

2-Indications: Severe Skeletal Class II   Correction of Occlusion Reduce overjet

Anteroposterior relationships ( Problem in patient cooperation, elastics, functional appliances, headgear… )Overjet is also known as “protrusion” of teeth, the lower teeth are too far behind the upper front teeth. In most Class II cases with abnormal upper proclination, it is advisable to extract teeth (14-24) only in the upper arch and to retract the maxillary incisors and canines. In case of the lower arch crowding it is advisable to extract in both the arches (34-44).

2-Indications: Severe skeletal Class III malocclusion Reduce Reverse Overjet

www.orthofree.com

REVERSE OVERJET IMPORTANT Class III cases are usually treated by extracting teeth only in the lower arch to discourage the forward growth of mandibe (34-44) Or surgery (15-25-34-44)
