  • Late maxillary protraction in patients with unilateral cleft lip and palate: a retrospective study.
    The Cleft Palate-Craniofacial Journal, 2014
    Co-Authors: Ali Borzabadi-farahani, Christianne J. Lane
    Abstract:

    Objectives: This retrospective study assessed the dentoskeletal effect of late maxillary protraction (LMP; Reverse-Pull Headgear, Class III elastics, and maxillary sutural loosening) in unilateral cleft lip and palate (UCLP) patients versus a control group of untreated UCLP patients. Materials and Methods: Cephalograms taken at age 13 to 14 years (T1) and 17 to 18 years (T2) were used for this study. The study group comprised 18 patients (10 male and 8 female, mean age at start of LMP therapy = 13.4 [0.45] years). A control groups of 17 patients (8 male and 9 female, mean age = 13.5 [0.44] years) was used for comparison. Results: The repeated-measures analysis of variance showed statistically significant changes across time between groups for the following variables (mean difference [T2–T1] in the study group, 95% confidence interval): SNA (°) (1.95, 0.75 to 3.15), A ⊥ Na Perp (mm) (1.82, 0.86 to 2.77), CoA (mm) (2.92, 1.53 to 4.31), ANB (°) (3.13, 2.02 to 4.24), Wits (mm) (7.82, 5.01 to 10.54), Mx-Md Dif...

Late maxillary protraction created a slight open bite (0.66 mm). Trends for overeruption of mandibular incisors and an increase in lower face height (P = .07 for both) were noted in the study group. Late maxillary protraction produced a combination of skeletal changes (protraction of maxilla, improvement in the maxillo-mandibular skeletal relationship) and dental compensations (counterclockwise rotation of occlusal plane, retroclination of mandibular incisors) in patients with UCLP. Late maxillary protraction was also associated with some unwanted tooth movements (open bite tendency, mandibular incisors overeruption).

  • Face mask therapy
    2020
    Co-Authors: Siddharth Mehta, Anjali Mehta, Surendra Lodha
    Abstract:

    This article presents a review of data in literature that deals with the use of face mask therapy for the treatment of Class III malocclusion in children. It is noted that the appliance system affects virtually all areas contributing to a Class malocclusion and can be applied to most developing Class III patients regardless of the specific etiology. It discusses the biomechanics of reverse pull Headgear and the recommended timing of treatment.

  • Timing for effective application of anteriorly directed orthopedic force to the maxilla
    American Journal of Orthodontics and Dentofacial Orthopedics, 1997
    Co-Authors: Daniel Merwin, Peter Ngan, Urban Hägg
    Abstract:

    Abstract Class III malocclusion with retrusive maxilla can be orthopedically corrected in the deciduous and mixed dentition, with Reverse-Pull Headgear in combination with rapid palatal expansion. The literature recommends this procedure be carried out before the patient is 8 years old to obtain the optimal orthopedic result. This statement, however, has not been supported by scientific data. The current study examined the treatment effects of patients younger than 8 years old (5 to 8 years) and patients older than 8 years old (9 to 12 years). Thirty patients treated with maxillary protraction and expansion in the Department of Children's Dentistry and Orthodontics, University of Hong Kong were included in this study. Cephalometric radiographs were taken 6 months before the initiation of treatment (T 0 ), at the initiation of treatment (T 1 ), and after 6 months of treatment (T 2 ). In this way, (T 2 -T 1 ) represented cephalometric changes during the treatment period and (T 1 -T 0 ) represented 6 months of growth changes without treatment. Experimental subjects served as their own control in this study. A grid system consisting of maxillary occlusal plane (OL) and a line perpendicular to OL through sella (OLp) was used for linear measurements. A total of 15 linear and 3 angular cephalometric measurements were made. A multivariate analysis of variance (MANOVA), which used age and treatment time as its factors, was used to determine effect of age and/or treatment on each cephalometric parameter. Results indicated strikingly similar therapeutic response between the younger and older age groups. These data suggest that similar skeletal response can be obtained when maxillary protraction was started either before age 8 (5 to 8 years) or after age 8 years (8 to 12 years).

In this way, (T2-T1) represented cephalometfic changes during the treatment period and (T1-To) represented 6 months of growth changes without treatment. Experimental subjects served as their own control in this study. A grid system consisting of maxillary occlusal plane ((31_) and a line perpendicular to OL through sella (OLp) was used for linear measurements. A total of 15 linear and 3 angular cephalometric measurements were made. A multivariate analysis of variance (MANOVA), which used age and treatment time as its factors, was used to determine effect of age and/or treatment on each cephalometric parameter.

  • management of skeletal class iii malocclusion with face mask therapy and comprehensive orthodontic treatment
    Contemporary Clinical Dentistry, 2016
    Co-Authors: Kirthika Muthukumar, N M Vijaykumar, M C Sainath
    Abstract:

    Orthopedic correction of skeletal Class III malocclusion in a growing patient is crucial as it can circumvent future surgical procedures. Further, as surgery is done only at a later stage, early treatment helps to avoid the detrimental effects produced by the facial disfigurement on the patient's social life. This case report describes the treatment of a child aged 9 years 6 months who had a skeletal Class III malocclusion. The treatment plan involved the use of a reverse pull Headgear (facemask) and multibracket appliance therapy resulting in successful correction of the malocclusion. The treatment results were highly satisfactory resulting in improved facial esthetics, a skeletal Class I with a Dental Class I molar and canine relationship, an ideal overjet and overbite. Thus, dentoalveolar camouflage, if done in properly selected cases, alleviates the need for surgical intervention. The patient is being monitored until the end of growth to ensure the stability of treatment results.
