Gummy Smile

A 21-year-old female presented with chief complaints of crooked teeth, canine impaction, deep bite, and “gummy smile” (excessive maxillary gingival exposure when smiling). Increased facial convexity (15.5°), increased lower facial height (56%), and incompetent protrusive lips (E-line to upper left 2 mm, E-line to lower left 2 mm) were associated with a severe Class II malocclusion (nearly a full cusp bilaterally). There was 7.5 mm of overjet, 100% anterior deepbite, and a left posterior buccal crossbite. Cephalometrics revealed a skeletal discrepancy due to a protrusive maxilla and a retrusive mandible (SNA 85°, SNB 78°, and ANB 7°). Cone-beam computed tomography imaging revealed a palatally impacted right maxillary canine (UR3) near to the adjacent lateral incisor (UR2). The retained right primary canine (URc) was extracted. A simplified open-window technique was utilized to surgically expose its impacted successor. A maxillary anterior mini-screw provided anchorage to align the UR3 in its correct anatomical position. Nonextraction treatment with a passive self-ligating fixed appliance was indicated to align and level both arches. Anchorage provided by infrazygomatic crest bone screws, and maxillary anterior miniscrews were used for the correction of Class II malocclusion and gummy smile. To achieve more esthetic crown lengths in the maxillary anterior segment, gingivectomy was performed with a diode laser 2 months after fixed appliances were removed. This challenging skeletal Class II malocclusion with a Discrepancy Index of 38 was treated in 32 months to excellent outcomes: Cast-radiograph evaluation score of 25 and an pink and white dental esthetic score of 2. All facial and dental corrections were stable at the 6 months follow-up evaluation (Int J Orthod Implantol 2017;48:24-46). Republished with permission from: Ariel Wong, Chang CH, Roberts WE.

Abstract This case report describes the treatment of a case involving a skeletal Class II facial profile with a gummy smile. While treating a facial profile and a gummy smile, the outcome may not always be successful with orthodontic therapy alone. For this reason, surgical therapy is often chosen to gain an esthetic facial profile and a good smile. However, sometimes the patients reject surgical treatment and an alternative method must be considered. Skeletal anchorage systems such as miniscrews are now frequently used for correcting severe malocclusion that should be treated by surgical therapy. In this case report, we treated a skeletal Class II malocclusion with a convex profile and a gummy smile using miniscrews, which were placed in the upper posterior and anterior areas. The active treatment period was 3.5 years, and the patient's teeth continued to be stable after a retention period of 36 months.

Background:Class II malocclusion is the most common sagittal skeletal discrepancy, with a prevalent skeletal pattern of mandibular retrusion. The correction of mandibular retrusion with functional removable appliance needs a good patient’s compliance; for this reason, some clinicians prefer to use no compliance apparatus.Objective:Objective of the present therapy note is to demonstrate that the use of no compliance apparatus can provide a good correction of skeletal class II malocclusion.Methods:In the present study, authors report a therapy note referred to a 10 years old patient, woman, affected by Class II, with mandibular retrusion and deep bite, treated in 2013 at the Dep. of Orthodontics of Messina University. An orthodontic treatment has been planned with the aim of stimulating mandibular growth; an Herbst appliance with a cantilever design, bonded on first maxillary and mandibular molars, has been used. After eleven months of functional therapy a bilateral molar class I have been obtained.Results:In the therapy note proposed, authors obtained a resolution of mandibular retrusion, a correction of overjet, overbite and dental crowding in both arches, and a bilateral molar and canine class I has been achieved.Conclusion:Herbst appliance seems to be efficient in the correction of II Class Malocclusion, independently from patient’s cooperation; moreover , early correction of Class II malocclusion with functional appliances produces several clinical advantages.

Functional appliance is an effective way of treating skeletal Class II malocclusion in children and adolescents. A 12 months stepwise mandibular advancement protocol with Herbst appliance has been proved to enhance condylar growth and improve mandibular prognathism. The present case report documents a 12-year-old boy presenting with Angle’s Class II, division 1 malocclusion associated with excessive overjet (11 mm), 100% deep bite, and retrognathic mandible. He was treated by a phase I growth modification therapy using twin block appliance with lip pads in a stepwise mandibular advancement protocol followed by a phase II preadjusted Edgewise appliance therapy.

Growth Modification

Skeletal class II malocclusion is best treated by growth modification using the myofunctional appliances or the orthopedic appliances or the combination of the both depending upon the type of malocclusion encountered during the growth period of an individual. Though all myofunctional appliances work on the same principle with few basic differences; the orthodontist has to make a choice among the plethora of the appliances at his disposal. The present article is a case report of class II malocclusion treatment using the Bass appliance for the growth modification, which was followed by fixed appliance for the occlusal detailing.

Management of skeletal class II relation in growing patient require careful evaluation of growth status, proper diagnosis and treatment plan to address the patient’s need. Twin block is the appliance of choice among functional appliance to correct the skeletal class II malocclusion due to it’s acceptability by the patient and simplified design. Maxillary canine impaction is the second most prevalent impaction after the third molars. Treatment of maxillary canine impaction is usually a challenge to orthodontic approach as the defect lies in the esthetic region of the jaw. This case report describes the orthodontic management of a 9 years male patient having skeletal Class II malocclusion with horizontally impacted maxillary canine. Some modifications in the treatment mechanics are deemed essential to address the patient’s need for achieving the optimal esthetic and to improve the occlusion. Twin block is beneficial for the treatment of skeletal malocclusion in a growing patient to achieve the maximum benefit. The orientation of impacted teeth may change from horizontal to favorable one, hence it should be considered a viable treatment alternative. In such case, early diagnosis and interception at the right time along with radiographic follow-ups are necessary to achieve successful results.

One of the goals of functional-appliance devices is to modify the vertical growth pattern, solving several kinds of malocclusion. This study aimed to evaluate Class II malocclusion treatment’s stability with Austro Repositioner, followed by fixed appliances, and assess its capacity to modify vertical dimensions in brachyfacial patients. A test group of 30 patients (16 boys and 14 girls, mean 11.9 years old) with Class II malocclusion due to mandibular retrognathism and brachyfacial pattern treated with Austro Repositioner and fixed appliance were compared to a matched untreated Class II control group of 30 patients (17 boys and 13 girls, mean age 11.7 years old). Lateral cephalograms were taken at T1 (initial records), T2 (end of treatment), and T3 (one year after treatment). Statistical comparisons were performed with a paired-sample t-test and two-sample t-tests. Significant improvements in the skeletal Class II relationship were observed in the treated group. The ANB angle decreased (4.75°), the SNB angle increased (3.92°), and the total mandibular length (Co-Pg) increased (8.18 mm) (p < 0.001). Vertical dimensions were also significantly modified, the FMA angle increased (3.94°), LAFH-distance increased (3.15 mm), and overbite decreased (3.35 mm). These changes remained stable one year after treatment. The Austro Repositioner was adequate for treating the skeletal Class II malocclusion resulting from the mandible retrusion in brachyfacial patients.

Treatment Alternatives

Class II malocclusion has a high incidence in the population, which may compromise smile aesthetics, occlusion function and stability. Skeletal Class II may affect facial aesthetics and upper airway volume. Class II malocclusion is routinely associated with skeletal Class II condition, having as treatment alternatives the use of Extra Buccal Appliance (EBA) or removable or fixed propulsor appliance. This article describes a case of a patient who did not accept the use of EBA and so it was fitted a Flex Developer propulsor for Class II correction and discussed the advantages and disadvantages of therapeutic alternatives for Class II correction.
