“…Patients who were treated without extraction did not cause any changes in the dimensions of the upper airway. 23 Halwa et al stated that alteration in tongue was due to the adaptation of changing dimensions of the upper airway. 23 Upper airway dimensions increased in patients with mesial molar movement, upper airway dimensions decreased due to retraction of anterior teeth, and upper airway dimensions did not change if the teeth were stable during treatment.…”

“…23 Halwa et al stated that alteration in tongue was due to the adaptation of changing dimensions of the upper airway. 23 Upper airway dimensions increased in patients with mesial molar movement, upper airway dimensions decreased due to retraction of anterior teeth, and upper airway dimensions did not change if the teeth were stable during treatment. The results of studies that were not significant on orthodontic treatment without extraction or with extraction of the alteration in upper airway were limited to the anatomy of the upper airway, and therefore further research is needed on respiratory function, especially on the functional of neuromuscular complex associated with OSA with a larger sample.…”

Correction of skeletal Class II malocclusion with camouflage orthodontic treatment generally requires the extraction of the maxillary first premolars to provide space for retraction of the maxillary incisors. Retraction of incisors changes the position of the incisors and the dimensions of the dental arch, which can cause changes in tongue posture and affect the upper airway. The purpose of this study was to determine the relationship between premolar extraction on the dimensions of upper airway and tongue posture in skeletal Class II malocclusion. This study was designed as a retrospective cohort using lateral cephalometric radiographs before and after orthodontic treatment. The samples in this study consisted of 44 samples of adult patients (n = 44) aged 18-40 years, who were divided into 2 groups: 22 subjects treated without premolar extraction and 22 subjects treated with premolar extraction. Lateral cephalometric radiographic analysis were used to measure the dimensions of the upper airway by analyzing superior posterior airway space (SPAS), middle airway space (MAS), inferior airway space (IAS), vertical airway length (VAL), and tongue posture (tongue length and height tongue) using imageJ software. No Statistically significant different changes were observed as seen from the following results: SPAS (p = 0.709), MAS (p = 0.365), IAS (p = 0.562), (p = 0.401), tongue length (p = 0.578), tongue height (p = 0.086) in the sample group without extraction premolar. No significant alterations in the upper airway and tongue posture measurement were observed in the sample group with extraction premolar. Premolar extraction with retraction on upper incisors did not affect upper airway dimensions and toung posture in skeletal Class II malocclusion.

“…Bimaxillary dental protrusion or bimaxillary protrusion is a condition where the anterior teeth of the maxilla and mandible are protruded relative to the maxilla and mandible basal bones. [1][2][3] The characteristics seen are an incompetent lip in a resting position, an excessive effort to close the lips completely, thus creating lip strain and prominent lips. [1][2][3] Bimaxillary dental protrusion is affected by race and ethnicity.…”

Background: Management of bimaxillary protrusion can be challenging and should be used with maximum anchorage to prevent loss of anchorage and improve the facial profile. In addition, a patient with a missing molar is often found in a dental clinic. Space closure can cause tipping movement rather than bodily, so couple force should be used. Purpose: This case report aims to manage the bimaxillary protrusion with a missing molar using a T-loop and a transpalatal arch (TPA) as maximum anchorage for correction of the facial profile and couple force to create bodily movement for the space closure of a missing first molar. Case: A 21-year-old female patient complained about her protruding teeth. An intraoral examination indicated Angle’s Class I malocclusion on the left molar relation, with the lower-right first molar missing, mild crowding maxilla and mandible, 6 mm of overjet and 5 mm of overbite, and midline shift at the maxilla and mandible. Case Management: The treatment plan was the extraction of teeth 14, 24, 34; alignment with pre-adjusted McLaughlin Bennett Trevisi (MBT) 0.022; retraction of the anterior segment with a T-loop, TPA, and close spacing of the missing first molar with couple force on the buccal and lingual side and tip back. Retention was done with removable retainers. At the end of the treatment, normal incisive inclination and closed space of the missing first molar were achieved, along with an improvement of the facial profile. Conclusion: Bimaxillary protrusion can be successfully treated by means of extraction of the premolar(s), space closure for correction of the profile with T-loop and TPA, and closing the space of the missing molar with couple force on the buccal and lingual sides and tip back.

“…1 Because of the negative perception of protrusive dentition and lips in most cultures, many patients with bimaxillary protrusion seek orthodontic care to decrease this protrusion. 2 The etiology of bimaxillary protrusion is multifactorial involving genetic and environmental. The environmental factors include mouth breathing, tongue thrusting habit, and tongue volume.…”

Correction of Bimaxillary Protrusion with Four First Premolar Extractions and T-Loop Mechanics – A Case Report

Bimaxillary protrusion is a condition characterized by proclined upper and lower incisors with an increased prominence of the lips. This is a case of a 18-year-old with bimaxillary protrusion, mild crowding on the maxilla and mandible, and mandibular dental midline shift to the left by 1 mm. The four first premolars were extracted using a pre-adjusted bracket. This bracket had in-built prescriptions of torque, tip, and in-out for orthodontic cases. There were three pre-adjusted orthodontic bracket systems: Andrews, Roth, and MBT. T-loop was also used to achieve controlled space closure. After 26 months of orthodontic treatment, the patient's profile was straighter and a pleasant smile was achieved at the end of treatment.
