Great results! Were you able to get a hold of the initial CBCT/records to see the pretreatment root positions? Just curious to see the extent of the incisor proclination and loss of bony coverage from the previous treatment. ■ Brbraces Member Since: 02/16/16 Post: 5 of 12 6/14/2020 Unfortunately, there were no pretreatment X-rays available. The images were of very poor quality, but showed severe crowding. ■ Fenrisúlfr Member Since: 02/25/09 Post: 6 of 12 6/14/2020 A really nice measurement to include in records is the inter molar distance of upper 6s should be about 36 or so. If narrower, widening can help to limit the protrusion you show. ■ danbraces Member Since: 11/09/08 Post: 9 of 12 6/15/2020 Can't widen beyond the alveolus, though. The decompensated lower arch is the template for the upper transverse. ■ Fenrisúlfr Member Since: 02/25/09 Post: 10 of 12 6/15/2020 dogtooth25 What would you consider to be the maximum lower incisor proclination acceptable? ■ 6/15/2020 There's no one number with regards to lower incisor position. The more important aspects to evaluate IMO are root positioning within the alveolus, the relationship between the lower incisors and the chin. For instance, low-angle subjects can have lower incisors at 105 degrees or so, but still have roots centered within the alveolous, and a good Holdaway ratio, so the goal would be to maintain or minimally alter that. ■ Member Since: 04/18/15 Post: 11 of 12 Fenrisúlfr Member Since: 02/25/09 Post: 12 of 12 6/16/2020 Get help with an ongoing case!
