| Summary: | The severity of bimaxillary proclination (bimax) cannot be objectively assessed because there’s no index to ration treatment. This study aimed to identify the prevalence of bimaxillary protrusion/proclination among orthodontic patients attending postgraduate orthodontic clinic at Faculty of Dentistry, Universiti Teknologi MARA and to categorise the severity and develop an index specific for bimaxillary proclination. The first part of the preliminary study was performed to obtain prevalence data of bimaxillary protrusion in general in which 100 profile photographs were chosen from postgraduate orthodontic residents patient’s list. They were analysed for its bimaxillary protrusion features by 2 operators at 2 occasions. In the second part of the preliminary study, 259 (first occasion) and 40 (second occasion) of profile and intraoral photographs were analysed by five assessors for skeletal and dental Class I bimax. Subsequently, 160 study casts of bimaxillary proclination cases were selected. All study casts were number coded. |
