WHAT IS WRONG WITH MY TEETH? Malocclusions (bad bites) are described under standardised groupings which have become accepted world-wide. These groupings allow universal classifi cation of problems and enable dental professionals to communicate using the same terms. CLASS I MALOCCLUSION CLASS II DIVISION 1 MALOCCLUSION CLASS II DIVISION 2 MALOCCLUSION CLASS III MALOCCLUSION Here the teeth meet in good positions, the overbite and overjet are correct, but the teeth might be crowded or displaced. Depending on the degree of displacement, the orthodontist will determine the kind of braces that would best treat the specifi c case. The upper teeth are projecting forwards of the lowers (the overjet is increased) and the upper incisors are proclined, or pointing forwards. Crowding may also be present. This arrangement is seen in about 34% of the population. Depending on the degree of discrepancy, functional braces, headgear, extractions or surgery may be needed to create a good correction. The upper incisors are retroclined (tipped backwards) although the upper jaw might be protrusive. The overbite is usually greatly increased (deep bite). About 18% of malocclusions are like this and the treatment is very similar to a class II division I malocclusion described above. In 2% of malocclusions, the lower teeth are positioned ahead of the uppers (a reverse overjet or complete class III). This is often associated with misalignment of either the upper or lower jaws. These cases may need a combination of braces and a jaw operation to correct the bite. Because the lower jaw is one of the last bones to stop growing, treatment is often delayed until the patients are adults, so that a correct treatment plan can be made. 38 Smiles & F aces The Comprehensive Guide To Orthodontics Octagon Orthodontics www.octagonorthodontics.com AN INTRODUCTION TO ORTHODONTICS
