Section A: Assessment of Severity: Pre-Treatment Cephalometric Analysis

Date of Ceph

2011-12-11

Measurement	Acceptable Range	Within Range? (Yes or No)
ANB	-1° to 7°	No
SNB	72° to 84°	No
LFH%	51% to 59%	No
Overjet	1.3mm to 5.3mm	No
Overbite	0.8mm to 6.8mm	Yes
UI / Mx	97° to 121°	No
Holdaway	7° to 14°	Yes
Severity Score = Number of Yes Grades (Possible Range 0-7, lower scores represent more severe pre-treatment)		2
Comparison with the National Outcomes Audit findings The Mean Severity Score in the National Audit was 3.8 with a standard deviation of 1.3. Therefore 68% of cases fell within the range of 2.5 to 5.1 in the National Audit. 3% of cases had the most severe scores of 1 or less; 16% had a score of 2 or less; 41% had a score of 3 or less; 69% of cases had a score of 4 or less; and 92% had a score of 5 or less. (e.g. A pre-treatment severity score of 2 would put that case among the most severe 16% of the national audit cases)

Section B: Assessment of Outcome: Post Treatment Cephalometric Analysis

Date of Ceph

2013-12-18

Measurement	Acceptable Range	Within Range? (Yes or No)
ANB	-1° to 7°	No
SNB	72° to 84°	Yes
LFH%	51% to 59%	No
Overjet	1.3mm to 5.3mm	Yes
Overbite	0.8mm to 6.8mm	Yes
UI / Mx	97° to 121°	Yes
Holdaway	7° to 14°	Yes
Outcome Score: = Number of Yes Grades (Possible Range 0-7, higher scores represent better outcome):		5
Comparison with the National Outcomes Audit findings The Mean Outcome Score in the National Audit was 5.4 with a standard deviation of 1.3. Therefore 68% of cases fell within the range of 4.1 to 6.7 in the National Audit. 20% of cases had the best score of 7 (best outcome); 52% had a score of 6 or above; 80% had a score of 5 or above; and 91% of cases had a score of 4 or above. (e.g. A post-treatment outcome score of 7 would put that case among the most best 20% of outcomes from the national audit)
