Use of direct miniplate anchorage in conjugation with Forsus Fatigue Resistant device in class II growing females: a randomized controlled trial

“…The results demonstrated that group I showed a statistically significant decrease in time needed for extraction space closure than group II for the upper and lower arches. This observation was in agreement with other studies (16,17) which reported reduced RAP effect when a flap was not reflected.…”

“…For group II (flapless technique), the results of the current study for retraction time was consistent with Tuncer et al, (17) for the upper arch. For the lower arch, no data was found in the available literature concerning the evaluation of piezocision for en-masse retraction of the lower anterior segment.…”

“…(16) In contrast to previous findings, it was found that piezocision was ineffective in accelerating tooth movement. (17) A significant increase in the rate of canine retraction was recorded in a recent study when piezocision and laser-assisted flapless corticotomy were investigated. (18) Bimaxillary protrusion is a common orthodontic problem characterized by proclination of maxillary and mandibular incisors, facial convexity and incompetent lips.…”

An unusual case of invasive cervical resorption after piezosurgery-assisted en masse retraction

“…Among the studies that reported retraction rates, ours falls within the range (0.51-0.85 mm/month) mentioned for miniscrew-supported en masse retraction without any intervention for rapid tooth movement. 7,57 When the numbers are taken into consideration, it is fair to say that retraction rate did not show a substantial increase. This can be explained with the fact that the anterior unit in this patient was composed of 7 teeth, unlike conventional en masse retraction.…”

“…1,2 Some of the cases treated with piezoincision-assisted orthodontics are canine distalization, en masse retraction, incisor decrowding, compensation of Class II and Class III malocclusions, and expansion. [3][4][5][6][7][8] Invasive cervical resorption (ICR) is a type of external root resorption that starts beneath the epithelial attachment and progresses toward the pulp chamber, which then changes direction apically and coronally once it reaches the predentin. 9 It circumvents the pulpal tissue and spreads in all 3 dimensions in a nontraditional way.…”
