Abstract

Background: Orthodontic treatment failure and unstable treatment results can lead to orthodontic retreatment. Excessive overjet, convexity, and upper and lower lip protrusion are common in Class II malocclusion. When combined with microdontia (smaller-than-average teeth), it presents unique challenges. Purpose: To describe retreatment of Class II, Division 1 malocclusion with microdontia using orthodontic and conservative approaches. Case: A 25-year-old female patient with a skeletal Class II relationship with bimaxillary retrognathism and protrusion of the lower incisors. An intraoral examination showed a Class II molar relationship on the right side, a deep overbite (5.47 mm), a large overjet (5.33 mm), multiple diastemas, and microdontia in tooth 22. Teeth #14, #24, #34, and 44 were extracted during a previous orthodontic treatment. Case management: Orthodontic retreatment was initiated with bracket placement using the edgewise technique. A multiloop archwire was installed to achieve leveling and alignment with a 0.14-inch stainless steel round archwire. Treatment involved bite opening with L loops, mesialization of teeth #11, #21, #12, and #22, retraction of the anterior segment, finishing, and root paralleling. After 22 months of orthodontic treatment, the brackets were debonded, and the patient received direct composite veneer treatment to reshape teeth #12 and #22. Post-retreatment facial evaluation showed a significant improvement in overall facial harmony. Intraoral examination showed Class I molar and canine relationships, good interdigitation, and adequate overbite (2.9 mm) and overjet (3.2 mm). Conclusion: Orthodontic retreatment of a Class II, Division 1 malocclusion with microdontia, when combined with conservative approaches, can significantly improve the patient’s facial profile and stomatognathic function.

Abstract

Background: Ectopically erupting canines are a common challenge in orthodontic practice, often occurring as a result of insufficient dental arch space. Failure to manage ectopic eruptions can lead to arch length loss and malocclusion. The main advantage of two-phase treatment using segmental loop mechanics is the absence of friction between the bracket and archwire during space closure, making it an efficient way to achieve canine retraction and minimizing loss of anchorage and anterior flaring. Purpose: To describe the effectiveness of using a two-phase orthodontic edgewise prescription without any side effects. Case: A 21-year-old female patient presented with a primary concern of crowding and misaligned canines. A dentoskeletal Class I relationship, lower dental midline shifted 4.15 mm to the right, 4.4 mm overjet, 3 mm overbite, and mesiobuccally ectopic #23 and #43 were detected. Case Management: Four premolars were extracted (#15, #24, #34, #44); segmented edgewise brackets with a 0.022” slot and 0.014” stainless steel archwires, complete with a vertical loop and helix, were installed and activated to retract #13 and #43 until they were aligned and leveled. The treatment proceeded with insertion of the remaining brackets, followed by leveling and alignment, canine retraction, posterior mesialization, and space closure. Treatment results showed correction of the ectopic canine position with a Class I relationship, overjet reduced to 2.3 mm, overbite reduced to 2 mm, and midline deviation reduced to 1.30 mm to the right. Conclusion: The two-phase orthodontic treatment using the segmental technique with edgewise prescription effectively corrected the ectopically erupting canines without revealing any side effects.

Abstract

Background: Delayed restoration in tooth loss can lead to tooth extrusion, bite collapse, and mastication difficulty, which reduce quality of life. Distal extension denture usage is challenging compared to bounded saddle dentures due to their comfort and denture longevity. Uprighting an impacted third molar can be a novel treatment option for transforming a free-end saddle into a bounded saddle. Purpose: The objective of this case report is to demonstrate reconstructive treatment of masticatory difficulty due to the prolonged loss of the first and second molars using orthodontic and prosthodontic approaches. Case: A 23-year-old female patient presented with complaints of protruding teeth and mastication difficulty on her left side. The patient was not recommended for odontectomy and implant. Incompetent lips with Class I skeletal patterns (ANB 3°), maxillary and mandibular incisor proclination (U1-NA, 35.87°; U1-NB, 49.07°), and lower lip protrusion were seen. Intraoral observations showed extrusion of #26 and #27, moderate lower arch crowding, fully impacted tooth #38, and missing teeth #36 and #37. Case Management: Facial profile improvement was achieved by extracting teeth #14, #24, and #44, and management of excessive space due to loss of teeth #36 and #37, followed by anterior retraction. Pre-prosthodontic preparation was managed by intrusion of teeth #26 and #27. A crown lengthening procedure was needed to expose the fully impacted #38, slight mesialization using temporary anchorage device was required due to distal movement limitation because of an external oblique mandible, and then uprighting of #38 was completed using copper nickel-titanium archwire sequences. Conclusion: The uprighting of the impacted third molar can be used as a novel strategy in transforming a distal extension denture into a bounded saddle denture that increases the patient's comfort and stability, and the longevity of the denture in a patient that was not recommended for odontectomy and implant.
