Εvaluation of a treatment protocol for unerupted maxillary central incisors: retrospective clinical study of 46 children

摘要: To evaluate the clinical outcome of a treatment protocol performed in children with unerupted permanent maxillary central incisors, including surgical removal any related obstruction and traction initiation one stage, under fully repositioned flap, combined pre- post-operative orthodontics for space creation final alignment. Forty-six patients aged 7.3–12.7 years (mean = 9.44 ± 1.36) having 54 impacted incisors were reviewed. The study group included 37 treated by us nine referrals eruption failure following previous various obstructions. Detailed patient’s radiographic data recorded. Aetiology 9 odontomas, 24 supernumerary teeth, 1 skeletal lack space, dentigerous cyst, 4 dilaceration, severe incisor MIH, 5 luxation injuries to primary predecessors coexisting dilaceration odontoma. total time standardised ranged from 21 months (mean 9.88 ± 3.10), while needed using different approaches (no pre-operative or then wait over an assessment period) 12 18 months 15 ± 2.12) 17 30 months 23.73 ± 5.14), respectively (p < 0.05). full alignment depended on inclination, height tooth (p = 0.001) age (p = 0.002). Additionally, absence dramatically increased (p = 0.018). In contrast, maturity developmental stage anterior teeth did not affect time. Finally, when location availability allowed waiting spontaneous eruption, was statistically that main (p = 0.545). studied appears ideal successful results minimum Space followed together orthodontic produces excellent results, is indicated only cases favourable location. Treatment operation required recommended, whereas unfavourable without simultaneous increases requires unnecessary second traction.
