Treatment Options for Jaw Growth Variations
TREATMENT OPTIONS FOR JAW GROWTH VARIATIONS An Editorial by Robert M. Mason, DMD, PhD PROBLEMS OF OVERGROWTH OF A JAW: It is well known among orthodontists that where there is a growth process involving overgrowth of a jaw, the rule is that growth should be allowed to proceed and then treat the situation after growth has ceased. The reason for this is that growth cannot be effectively stopped or otherwise modified to the extent that jaw growth can be overpowered; that is, “Mother Nature” is smarter than any of us in dentistry. What can be accomplished with an overgrowth of a jaw, however, is orthodontic “remodeling” of some of the parts which are expressing overgrowth. An example is a Class III “growing” mandible. Functional appliances, such as the Frankel or Bionator, can influence the shape of the growing mandible by remodeling, which may give the appearance of manipulating growth, while instead, long-term studies show that such jaw shape changes are only temporary. Over time, the overgrowth pattern returns. Hence, the orthodontic caveat: it is best to let a mandible grow to its full extent and then treat it either by a combination of jaw surgery and orthodontics, or orthodontics alone which may amount to “camouflaging” the problem. What happens dentally in the example of overgrowth of the mandible is that in an attempt for the body to try to maintain dental contacts, the lower incisors tip lingually and the upper incisors tip labially (facially) in an attempt to maintain anterior dental contact relationships as lower jaw growth continues. If the treatment decision is to try to correct the problem with orthodontics alone, Class III elastics would be used along with orthodontic fixed appliances to maintain the lingual tipping and maxillary flaring of incisors. -

Pattern of Third Molar Impaction; Correlation with Malocclusion and Facial Growth SograYassaei1, Farhad O Wlia2, Zahra Ebrahimi Nik3 1Associate professor, Department of Orthodontics, Faculty of Dentistry, Shahid Sadoughi University of Medical Sciences, Yazd 89195/165, Iran. 2Faculty of Dentistry, Shahid Sadoughi University of Medical Sciences, Yazd, Iran.3Postgraduate student of orthodontics, Department of Orthodontics, Faculty of Dentistry, Shahid Sadoughi University of Medical Sciences, Yazd 89195/165, Iran. Abstract Background: The aim of the present study was to evaluate the type of mandibular and maxillary third molar impaction in different malocclusions and facial growth patterns. Method and materials: In this descriptive cross sectional study, 364 impacted third molars of patients referring to the orthodontic department of Yazd University were assessed radio graphically. Also, the type of malocclusion and the facial growth pattern was determined by analyzing their lateral cephalograms. Collected data were entered to a computer and statistical tests (Chi-square) were carried out using SPSS16. Results: Significant correlation was found between the type of mandibular third molar impaction (based on Pell Gregory classification) and different types of malocclusion. Also, the dominant form of impaction (based on winter classification) among different types of facial growth pattern was the vertical one. Conclusion According to the results of this study, the vertical level of mandibular third molar impaction relative to the adjacent second molar impaction was statistically associated to the type of malocclusion. Also, we found no correlation between the M3s impaction and the type of facial growth pattern. Key Words: Third molar Impaction, Malocclusion, Facial growth pattern Introduction (2010) found higher incidence of mandibular M3s impaction The impacted tooth is one that fails to erupt into the dental in malocclusion class III [3]. -

The treatment was started with Delaire mask and RPE. At the end of this treatment (9 months) he had a tete-a-tete bite in the front and the upper arch was successfully expanded. Treatment was continued with Class III and open bite elastics, but the patient is not compliant in wearing the elastics. His second year in treatment, there is deviation of the mandible to the right and the bite cannot be closed with elastics. How would you proceed with the treatment?

Restriction in Infants
Introduction Ankyloglossia is a congenital anomaly characterized by presence of a hypertrophic lingual frenulum which is short and attached to the very tip of the tongue, limiting its normal movements. Clinically the patient cannot protrude the tongue past the incisal edge of the gingiva and the tongue becomes heart shaped when attempted to protrude. The restricted movements of the tongue can result in problems with breast feeding, lactation, speech disorders and other oral motor disorders like problems with swallowing and licking.1,2 The clinical significance of this anomaly and symptoms produced and the best method of management have been the subject of debate for some time. A review of the relation between the above problems and ankyloglossia is presented. Review Tongue is an accessory organ of importance in mastication, deglutition and speech; many authors describe its stimulatory influence on the development of the dental arches.3 At birth, the tongue unconfined by the teeth, extends outward between the maxillary and mandibular occlusal gum pads. The “infantile swallow” with jaws parted and tongue placed between the jaws is replaced by the adult swallow at the age of two and half years of age. At the start of the normal adult swallow, the lips are closed, the teeth are brought into full occlusion, and the tip is raised and placed against the anterior portion of the palate. The respiratory opening, the nasal cavity, and the anterior portion of the mouth are all sealed off as the tongue, in a sweeping and undulating motion, sweeps backward the mass of chewed food.3,4 The tongue is always short at birth and the tip of the tongue is yet incompletely developed. -

Methods: Digital twins were reconstructed for a total of 50 adult female patients using facial scans and cone-beam computed tomography (CBCT) images. The anteroposterior position of the maxillary central incisor and the forehead inclination were measured. Results: The control group presented a mean of 6.7 mm for the sagittal position and 17.5◦ for forehead inclination. -

Maxillary Protraction with Miniplates Providing Skeletal Anchorage in a Growing Class III Patient
CASE REPORT Maxillary protraction with miniplates providing skeletal anchorage in a growing Class III patient Bong-Kuen Cha,a Dong-Soon Choi,b Peter Ngan,c Paul-Georg Jost-Brinkmann,d Soung-Min Kim,e and In-san Jangf Gangneung and Seoul, South Korea, Morgantown, WVa, and Berlin, Germany Maxillary protraction headgear has been used in the treatment of Class III malocclusion with maxillary de- ficiency. However, loss of dental anchorage has been reported with tooth-borne anchorage such as lingual arches and expansion devices. This side effect can be minimized with skeletal anchorage devices such as implants, onplants, mini-implants, and miniplates. The use of miniplates for maxillary protraction in the mixed dentition has not been reported in the literature. This case report describes the treatment of an 8-year-old girl with a Class III malocclusion and maxillary deficiency. Miniplates were used as skeletal an- chorage for maxillary protraction followed by phase 2 orthodontic treatment with fixed appliances. Skeletal, dental, and facial changes in response to orthopedic and orthodontic treatment are reported to illustrate the esthetics, function, and stability of treatment with this new technique.
