Lower Arch Distorted arch form Distorted Arch Introduction Patient is a 15.6-year-old boy. Chief complaint: significant anterior spacing (aesthetics). Problem list: Class 1 buccal segments. Significant generalized U+L spacing: U 9.04mm L 9.15mm. Certainly some potential measurement errors, but in the ballpark of 9mm in both arches. Incisal angulation: U within normal range but could be proclined. Do not think they should be uprighted. L mild-mod upright at 88 to MP and 15 to NB. Interincisal angle: 144. Low MPA (15). Mild skeletal Class 3 tendencies: ANB -1 (78/79); Wits: -1.8mm. Short clinical crowns UR1+UL1 (Most recent center IO photo not well1> 2> focused). Incisal wear or chipping noted. Max. frenum is an issue. UR+UL 6s derotated. Late dental developer. A bit of an over-closed facial balance appearance. In my opinion, a significant component to the overall problem is a prosthetic issue. My experience is when we try to solve prosthetic problems with orthodontics alone, the result is a lot of time spent in ortho treatment with an often less-than-optimal result. Conclusion I am most interested in how other Orthotownies would address this case. Thank you. n FEB 13 2015 tom525 Member Since: 06/18/08 Post: 2 of 6 Late dental development. Wait till the maxillary canine erupts. I use open coils in these cases to push the anterior teeth forward first. Then I move progressively back with premolars, and then finally the molars are protracted with closing loop arches. You could use palatal implants to support the anchorage and move things along faster, if you wish. n FEB 13 2015 str8nerinva Member Since: 03/12/08 Post: 3 of 6 Using TADs to do what you described-moving the posterior forward-makes sense, but is a long haul. I would like to see some examples of cases done this way. This case is not all that rare, so hopefully someone will be able to show a case treated this way.
