ABSTRACT
Camouflage orthodontics is a treatment alternative based upon rendering moderate or light dental-skeletal anomalies less evident through instauration of merely dental-alveolar movements. Mandibular asymmetries are a special group of maxillary anomalies which develop at embryonic stage as well as after birth. They can be due to hyper- or hypo- growth of a hemi-mandible, or by a combination of both. Retained canines are a relatively common dental eruption anomaly in general population. This represents, among other collateral problems, a root integrity risk for adjacent teeth. Therefore, a decision must be made to perform traction to move them towards the dental arch, or, alternatively, it can be decided to surgically extract them so as to avoid complications during treatment. Missing teeth can represent a challenge for the orthodontist, when designing treatment plan. He must decide whether to preserve space for a future prosthesis or to close spaces through orthodontic movement of adjacent teeth, which will in turn functionally substitute missing teeth. This article presents camouflage orthodontic treatment performed on a 29 year old female patient. Diagnosis emitted for this patient was as follows: skeletal Class II malocclusion, moderate dental-facial asymmetry, retained upper right canine and left lower third molar, as well as absence of left lower first molar. To this effect a Pro-torque slot .0128 x .025 straight wire appliance was used. Three first premolars and retained canine were extracted and left lower second and third molars were subjected to mesialization.
