ABSTRACT

The aim of this study was to describe the successful treatment of an anterior open bite in an adult Class II hyperdivergent patient. A 31-year-old female presented for orthodontic treatment, seeking an aesthetic solution to correct her anterior open bite and lower crowding to enhance her smile. As an initial step, all third molars were extracted to facilitate the forward rotation of the mandible and the initial closure of the open bite. Subsequently, clear aligner therapy (F22 aligners, Due Carrare, Italy) was initiated, with aligners changed every 15 days in combination with Class II elastics. Bite closure was achieved through programmed interproximal reduction (IPR) and the retroclination of anterior teeth. At the end of treatment, the open bite was successfully closed, a Class I relationship was obtained on the right side, and an edge-to-edge Class II relationship persisted on the left due to underlying skeletal asymmetry. Additionally, incisor exposure during smiling was improved. This clinical case demonstrates that clear aligners can effectively compensate a functional anterior open bite by promoting mandibular forward rotation and incisor retroclination.

ABSTRACT

This case report describes the successful non-extraction orthodontic treatment of a 13-year-old female patient affected by a Class II Division 2 malocclusion, maxillary constriction and a unilateral impacted maxillary canine. The miniscrew-assisted palatal expansion (MAPA) system was used for precise palatal miniscrew placement, achieving bicortical engagement. A hybrid T-Rex rapid palatal expander was then employed to achieve both skeletal expansion and molar distalization without requiring patient compliance. After that, tooth 2.3 was surgically exposed and orthodontically repositioned with a miniscrew-supported extrusion cantilever on a fixed vestibular appliance and piggyback mechanics. The orthodontic treatment was completed in a total of 31 months, yielding satisfactory intraoral results. Precise digital planning for palatal miniscrew insertion was instrumental in achieving bicortical anchorage, enabling the efficient use of a single multipurpose, miniscrew-supported palatal appliance.

ABSTRACT

This case report describes a complex full-step asymmetrical Class II division 1 high-angle in an adult patient treated by extraction of compromised first molars with a preadjusted lingual appliance. Since the patient presented severe sagittal and vertical discrepancies combined with an Izard orthofrontal profile with upper lip protrusion, an extraction camouflage was performed with the twofold aim of obtaining ideal occlusal relationship and profile improvement, correcting occlusal plane cant by selective intrusion with interradicular miniscrews. Appropriate biomechanical strategies, including extraction choice and anchorage control during space closure, were needed to achieve the planned results. This case report demonstrates the possibility of solving successfully severe sagittal and vertical discrepancies with significant asymmetric component in adult patient without surgical treatment by means of a completely invisible technique, with the extraction of the most compromised teeth in both arches. This report also underlines the need for careful planning during both diagnostic and treatment phases, with appropriate skeletal anchorage management, in order to obtain the best results.

ABSTRACT

This article describes one adult bilateral full-step class II case with severe initial upper incisors retroclination successfully treated by a completely invisible lingual appliance. A non-extraction treatment to compensate for the severe sagittal discrepancy was made possible following the excellent patient cooperation with intermaxillary elastics, combined with upper arch en-masse effective distalization with miniscrews. The application of an auxiliary torque spring was essential to increase upper incisors torque during class II mechanics. This case report shows the possibility of obtaining a full-step class II correction in an hypodivergent adult patient with a completely invisible appliance, taking advantage for the patient cooperation, for a more straightforward and faster non-extraction case resolution. It also underlines on the other hand the importance of successfully controlling incisors torque with auxiliaries in cases of severe retroclination in an adult class II malocclusion, in combination with the simultaneous distalization mechanics for monolateral full-step class II correction, by means of a completely invisible appliance.

ABSTRACT

This case report describes the treatment of a Class II malocclusion with upper lateral incisors agenesis in an adult patient, performed by an invisible preadjusted lingual appliance, monolateral space opening and dental Class II correction. The patient had previously been treated by clear aligners with the insertion of an implant in upper right canine position in order to close the remaining space. With the twofold aim of obtaining ideal occlusal relationship and smile aesthetic improvement, it highlights how a fixed orthodontic technique is needed to achieve the planned results, when anterior torque, bodily translations and deep-bite correction are necessary. On the other hand, it underlines how the treatment plan should not be adapted to the limits of the employed appliance, but should aim for the best clinical result for the patient. A prosthetic finalisation was in the end performed in order to obtain the best aesthetic result.

ABSTRACT

INTRODUCTION: The aim was to compare the soft tissue changes in pretreatment and posttreatment facial scans of patients who had undergone various orthopedic treatments vs a control group of untreated growing patients.

METHODS: Facial scans were performed before (T0) and after (T1) orthopedic treatment in 15 patients prescribed rapid palatal expander (RPE), 15 cervical headgear (HG), and 15 facemasks (FM), as well as 6 months apart in 15 untreated growing patients. After best-fit scan alignment using Geometric Control X software (3D Systems Inc, Rock Hill, SC), a 3-dimensional (3D) analysis of soft tissue changes was performed, comparing 3D reference points (total 22) and 8 areas on T0 and T1 scans. Kruskal-Wallis nonparametric tests and pairwise comparison with Bonferroni’s correction were applied to identify any statistically significant differences among groups (P <0.05). All analyses were conducted with SPSS software (version 28; IBM, Armonk, NY).

RESULTS: At T1, reduced soft tissue projection was found at the nose and upper lip in the HG group, the lower lip in the HG and RPE groups, and the chin in the FM and RPE groups. The RPE group displayed a statistically significant increase in facial divergence, confirmed by gnathion position (RPE vs FM [P = 0.018] and RPE vs control [P = 0.046]), as well as an increase in the soft tissue projection of both cheeks (left cheek in range of 1-2 mm [P = 0.030] and range of 0 to -1 mm [P = 0.022]; right cheek in range of 1-2 mm [P = 0.003] and range -1 to -2 mm [P = 0.001]). There were no clinically significant differences among groups in mandibular right and left body areas.

CONCLUSIONS: The 3D facial analysis revealed significant differences in soft tissues among orthopedic treatments, especially at the upper and lower lip and chin areas, as compared with untreated patients.
