VI. Pathological Analysis

  1. The maxillary and mandibular midlines are normal; the chin point is basically aligned and the lips are slightly tilted to the right. Facial type: reverse overjet (crossbite) with a protrusive chin. Maxillary arch: Class III crowding; mandibular arch: Class I crowding. Anterior occlusal relationship: crossbite (reverse overjet); molar occlusal relationship: tending toward Angle Class III occlusion.
  2. Maxillary teeth 11 and 21 are excessively labially inclined and protrusive, 12 and 22 are lingually inclined, and 13, 23 and 25 are buccally displaced, with considerable overall arch malposition. Mandibular teeth 31 and 41 are crowded and rotated, 44 and 45 are lingually inclined, the anterior occlusal plane is uneven, and the overall mandibular arch is anteriorly positioned.

VII. Initial Diagnosis

  1. This case is confirmed to be suitable for clear aligner treatment, but it is a case of complex difficulty. The platform must closely monitor the patient's aligner wear and schedule follow-up appointments on time.
  2. This case focuses on correcting the crossbite (reverse overjet), re-establishing the molar occlusal relationship, optimizing the arch form, improving the facial profile, and enhancing aesthetics. Combined clear aligner techniques such as mesial movement, arch expansion, and TB will be used.
  3. Treatment duration: maxillary arch 37 steps (18-19 months); mandibular arch 49 steps (24-25 months).
  4. After treatment, a retainer must be worn for 1 year to prevent the treatment results from relapsing.

Note: All clear aligner treatments require good patient compliance. The aligners must be worn as instructed and in the correct order to ensure optimal treatment outcomes.

VIII. Maxillary Treatment Procedure

Key points of maxillary treatment:

  1. Nine attachments need to be bonded to the maxillary teeth to provide anchorage for the clear aligners.
  2. Key challenges: aligning the dentition and re-establishing occlusion.
  3. Attachment moments are used to align the dentition, optimize the overall arch form, adjust the vertical level of the molar region, and re-establish the occlusal relationship to achieve effective occlusion.

IX. Mandibular Treatment Procedure

Key points of mandibular treatment:

  1. Seven attachments need to be bonded to the mandibular teeth to provide anchorage for the clear aligners.
  2. Key challenges: distalizing the dentition and retracting the anterior teeth.
  3. The TB appliance and Class III elastics are used to distalize the entire dentition; the space created by distalization is used to retract the anterior teeth, align the dentition, and optimize the overall arch form to achieve normal overbite and overjet.
Mandibular treatment illustration
Fig.4 Mandibular treatment illustration

X. Orthodontic Procedure Explanation

  1. The main function of bonded attachments is to help retain the clear aligners and to provide additional anchorage.
  2. The main function of pressure ridges is to help the clear aligners provide unidirectional force, such as intrusion and lingual movement.
  3. The main function of Class III elastics is to assist the clear aligners in effective mesiodistal tooth movement.
  4. Interproximal reduction (also called enamel stripping or IPR) is polishing the spaces between teeth to create room for tooth movement.
  5. TB improves maxillomandibular sagittal discrepancies through inclined-plane guiding forces during occlusion, leading to jaw movement.

6. Pathological Analysis

  1. Maxillary and mandibular midlines deviate 2mm to the left; chin point essentially centered; lip soft tissues symmetrical; facial type: dental bimaxillary protrusion; maxillary arch crowding Class I, mandibular arch crowding Class I; anterior occlusion: increased overjet and overbite; molar occlusion: tendency toward Angle Class II;
  2. Maxillary 11 and 21 excessively labially inclined and protruded; 14 and 24 lingually inclined; 15 buccally displaced; overall dental arch narrow and elongated; mandibular 31, 41 and 42 crowded and protruded; 18, 28, 38 and 48 present;

7. Initial Diagnosis

  1. This case can be treated with clear aligner therapy, but it is a case of complex difficulty requiring close monitoring of the patient's aligner wear and timely follow-up;
  2. This case focuses on correcting bimaxillary protrusion of the anterior teeth, stabilizing molar occlusion, optimizing arch form, significant retraction, and improving facial profile and aesthetics. Combined clear aligner techniques such as mesial movement, expansion and extraction will be adopted;
  3. Treatment duration: maxillary 61 steps (30-31 months), mandibular 59 steps (29-30 months);
  4. After treatment, a retainer should be worn for 1 year to prevent relapse;

Note: All clear aligner treatments require good patient compliance. Aligners must be worn in order as instructed to ensure optimal treatment results.

8. Maxillary Treatment

Key points of maxillary treatment:

  1. 9 attachments need to be bonded on the maxillary teeth to enhance anchorage for the aligners;
  2. The key difficulty is correcting the protrusion of the anterior teeth and optimizing the overall arch form;
  3. Extraction spaces of bilateral first premolars will be used to retract the anterior teeth, resolving lip protrusion; mesial movement of the molars will then close the remaining spaces and optimize the molar occlusion;

VI. Pathological Analysis

  1. The maxillary and mandibular midlines deviate 2.1 mm to the left; the chin point is basically aligned and the lip soft tissues are symmetrical. Facial type: average-angle, slightly convex profile. Maxillary arch: Class II crowding; mandibular arch: Class III crowding. Anterior occlusal relationship: Class II overbite and overjet; molar occlusal relationship: tending toward Angle Class II occlusion.
  2. Maxillary teeth 11 and 21 are excessively labially inclined, and 12 is rotated; the bilateral premolar regions are inclined inward of the arch. Mandibular teeth 31 and 41 are crowded and proclined, and 34, 44 and 45 are lingually inclined; overall crowding is present and the anterior occlusal plane is uneven.
  3. Teeth 18, 28, 38 and 48 are present.

VII. Initial Diagnosis

  1. This case is confirmed to be suitable for clear aligner treatment, but it is a case of complex difficulty. The platform must closely monitor the patient's aligner wear and schedule follow-up appointments on time.
  2. This case focuses on correcting the anterior overbite and overjet, stabilizing the molar occlusal relationship, optimizing the arch form, aligning the midlines, improving the facial profile, and enhancing aesthetics. Combined clear aligner techniques such as interproximal reduction (IPR), arch expansion, and elastics will be used.
  3. Treatment duration: maxillary arch 45 steps (22-23 months); mandibular arch 42 steps (21-22 months).
  4. After treatment, a retainer must be worn for 1 year to prevent the treatment results from relapsing.

Note: All clear aligner treatments require good patient compliance. The aligners must be worn as instructed and in the correct order to ensure optimal treatment outcomes.

VIII. Maxillary Treatment Procedure

Key points of maxillary treatment:

  1. Six attachments need to be bonded to the maxillary teeth to provide anchorage for the clear aligners.
  2. The key challenge is correcting the anterior protrusion and optimizing the overall arch form.
  3. Strong anchorage elastics are used for molar distalization and arch expansion, and then interproximal reduction creates space to retract and align the anterior teeth, achieving an aesthetically aligned anterior segment and an optimized, stable molar occlusion.
Fig.3 Maxillary treatment illustration
Fig.3 Maxillary treatment illustration

IX. Mandibular Treatment Procedure

Key points of mandibular treatment:

  1. Six attachments need to be bonded to the mandibular teeth to provide anchorage for the clear aligners.
  2. Key challenges: aligning and intruding the anterior teeth; labial inclination of the premolars.
  3. Elastics are used first to optimize the arch form in the molar region, then the space is used to align the dentition and the midlines; pressure ridges intrude the anterior segment to establish a proper occlusal plane.
Fig.4 Mandibular treatment illustration
Fig.4 Mandibular treatment illustration

X. Orthodontic Procedure Explanation

  1. The main function of bonded attachments is to help retain the clear aligners and to provide additional anchorage.
  2. The main function of Class II elastics is to assist the clear aligners in effective mesiodistal tooth movement.
  3. Interproximal reduction (also called enamel stripping or IPR) is polishing the spaces between teeth to create room for tooth movement.
  4. The main function of pressure ridges is to help the clear aligners provide unidirectional force, such as intrusion and lingual movement.

Note: If you do not understand any of the professional details, the platform will arrange a professional doctor to explain the plan by phone.

  1. 下颌牙齿需粘接6个附件,为矫治器提供支抗。
  2. 关键难点:前牙排齐与压低;前磨牙唇向倾斜。
  3. 先用皮筋牵引优化磨牙区牙弓形态,再利用间隙排齐牙列并对齐中线;压力嵴压低前牙段,建立正常咬合平面。

X. 正畸操作说明

  1. 粘接附件的主要功能:帮助矫治器固位,并提供额外支抗。
  2. II类牵引的主要功能:协助矫治器进行有效的近远中向牙齿移动。
  3. 邻面去釉(又称片切或IPR):打磨牙齿邻面,为牙齿移动创造空间。
  4. 压力嵴的主要功能:帮助矫治器提供单向力,如压低与舌向移动。
