Winter IJO Abstract (Click the title to read full article)
This article presents a case of a 13-year and 2-month-old female (Afro – Canadian), with Class I/III skeletal and Angle Class I, Division 1 dental malocclusion, with a slight hyper-divergence. The patient had an anterior open bite due to a long-standing thumb sucking habit and the consequential functional abnormalities that are associated with the habit. The patient had a reverse swallow, anterior tongue thrust, and she was a habitual mouth breather. This complex case was treated firstly with an orofacial-myofunctional therapy (OMT) approach and placement of a tongue thrusting and thumb sucking habit breaker. These interventions were followed by a Straight Wire Appliance protocol and then retentive appliances. Despite a COVID epidemic and poor compliance and cooperation, the authors were able to finish the case in 20 months.
The post-treatment followup was an interesting and satisfying experience. When the patient arrived three years post treatment not wearing the removable retainer at all, the teeth had settled into a better occlusion than when we had initially finished the treatment. Orofacial-Myofunctional therapy may have been an important factor in the improved stability of this case.
Distal end cutter is used intraorally to cut the excess of archwire protruding through buccal tube of the dital molar in fixed orthodontic treatment. The distal end cutter has contra angled beak with inserted tungsten carbide tips.1 The distal end cutter’s tungsten carbide cutting tip is approximately 10-12 mm in length. Depending on the manufacturer, length of the cutting tip may vary. For the understanding purpose of this article, the color coding of the cutting tip of the distal end cutter is done. The outer half length of the cutting tip is depicted in white color and the inner half in red color.
Impacted teeth can have various effects on the surrounding structures and in the development of a proper occlusion. The definition of impaction is tooth retention due to an obstacle in the eruption path or ectopic position of the developing tooth. Primary or secondary retention is defined as an impaction that occurs without an obstacle in the eruption path, either before or after gingival emergence, respectively.2 Tooth impaction occurs in almost 20% of the population.3 The most commonly seen impactions in clinical practice are the mandibular or maxillary third molars, maxillary canines, or central incisors, and mandibular second premolars.1 Impaction of a second molar is usually not a concern from a patient’s perspective because the patient is unaware of the condition and is often diagnosed incidentally. Impaction of the mandibular second molars is relatively rare, occurring in only 0.06- .3% of the population,4-6 but a higher incidence of 2-3% has been reported among orthodontic patients.7 A prevalence of 1.8% was found for second mandibular molar impaction in orthodontically treated patients.
A prospective cohort study was carried out at four different time intervals: T1 (pre-surgical), T2 (post-surgical), T3 (debonding), and T4 (8 years on average). The 23 outpatients who reported in tertiary hospital with skeletal class II dentofacial abnormalities included in study who underwent and successfully completed orthognathic surgery throughout the time frame of September 2008 to September 2015. The following cephalometric characteristics were examined: B, Go, Me, PoG, OJ (five horizontal and five vertical each) and GA, IA, MPA, RI, SNB (five angular). Surgical stability was assessed by evaluating the relapse rate over four different time intervals. Pre- and post-surgical relapse rates (T1 and T2), post-surgical relapse rates and debonding rates (T2-T3), and post-debonding and post-eight-year follow-up rates (T3 and T4) were all compared. The changes observed with respect to all the measured cephalometric parameters were subjected to repeated measures Analysis of Variance (ANOVA) where pair wise comparison was conducted for every parameter at four different time intervals. The comparison between pre-surgical and post-surgical (T1 and T2) and changes post debonding and post eight year follow up (T3 and T4) has been shown in Table 3. All parameters show statistically significant differences between time interval T1 and T2 (P-value>0.05). Whereas while evaluating the stability of the outcomes between T3 and T4, it was observed that no parameters showed statistically significant differences that showed skeletal stability even after long term evaluation. The SFOA is effective and reliable method as seen in follow up cases for long term duration.
The success of your practice comes down to one simple truth: you can’t wait for better patients to walk in the door – you have to create them. And you do this by following a powerful process: educate and elevate.
This study investigates dental arch widths relative to vertical facial patterns in Class II Division I malocclusion, examining variations across horizontal, average, and vertical growth patterns.
The Sidekick is a bondable hook which was engineered to work seamlessly with Carriere Motion 3D Appliances, as opposed to other hook options. Features include low profile for comfort, a micro-etched base for bond strength, and a hook shape to better hold elastics in place.
