“…Following enameloplasty, color correction should be considered to brighten the teeth using bleaching techniques. [21][22][23] Moreover, the restorative procedure has to be completed at least 3 or 4 weeks after dental bleaching to prevent any negative effects of bleaching on bond strength and stabilize the color. 24 Dental morphology and ideal tooth proportion were also important in the treatment plans for the three present cases.…”

Maxillary lateral incisor agenesis is a condition that significantly compromises smile esthetics, which is particularly worrying in young patients. This article shows how the combination of non-invasive treatments and current restorative options may improve clinical outcomes following orthodontic treatment for symmetric and asymmetric maxillary lateral incisor agenesis and microdontia. Teeth were treated with conservative resin restorations in three separate cases: two of congenitally missing maxillary lateral incisors (i.e., unilateral and bilateral) and one of microdontia. After presenting the clinical results, this article summarizes how bleaching, enameloplasty, and bonding with composite resin can enhance esthetics and functions following orthodontic space closure. The cases reveal that carefully planned, methodically executed orthodontic and restorative approaches can achieve predictable, esthetic outcomes that will improve the patient’s self-esteem with a minimally invasive solution.

“…Treatment plan B describes the surgical removal of the unerupted UR1 and UL1 and restorative camouflage with anterior composite resin build-ups; however, disguising canines as lateral incisors comes with both orthodontic and restorative challenges, such as the canine having a greater mesiodistal width, greater bucco-palatal width, greater crown length, higher gingival level, the canine eminence and canines tending to be darker in shade (Lewis, 2010). Large gaps are associated with camouflaging a smaller lateral incisor as a larger central incisor, often leading to a broad 'tombstone' appearance and poor aesthetic results (Westgate et al, 2019). A study that reviewed 1821 anterior composite resin restorations showed a failure rate of 24.1%, mainly due to fracture or for aesthetic reasons (Demarco et al, 2015).…”

Use of 3D printing in the planning of a patient with unerupted maxillary central incisors

Impacted central incisors are a clinical dilemma faced by orthodontists, oral and maxillofacial surgeons, paediatric and restorative dentists. Successful management requires a robust diagnosis and treatment planning process. This case report highlights the use of 3D printing to aid the treatment planning of a patient with bilateral unerupted maxillary central incisors due to two supernumerary teeth acting as a physical obstruction. The preoperative cone beam computed tomography scan allowed for production of the printed model to the exact size and dimensions of the unerupted teeth and supernumeraries to facilitate the planning of the case and to aid in consenting the patient for treatment.

“…A missing bilateral maxillary lateral incisor MBMLI, which is not accompanied by the absence of any other teeth other than the third molars, is called mild hypodontia [7]. Patients with MBMLI seek orthodontic treatment with high aesthetic expectations due to the anterior location of the malocclusion [8].…”

A missing bilateral maxillary lateral incisor (MBMLI) causes aesthetic and functional problems and a multidisciplinary approach is required for treatment. This study aimed to compare the changes in the mesiodistal axial angulations of the maxillary canines and central incisors with orthodontic treatment of MBMLI. (2) Methods: A total of 56 patients with MBMLI were included in the study, and three groups were formed: the control group (Group 1, n = 20) with untreated ideal occlusion and the space opening (Group 2, n = 20) and space closure (Group 3, n = 16) groups as treated study groups. The mesiodistal angulations between the long axes of the maxillary right canine (tooth no 13), right central incisor (tooth no 11), left central incisor (tooth no 21) and maxillary left canine (tooth no 23), and the bicondylar plane, were measured on the panoramic radiographs taken pre (T0) and post treatment (T1). p < 0.05 was accepted for statistical significance. (3) Results: At T0, while there was no significant difference between the mesiodistal angulations of the right–left maxillary canines and central incisors in all groups (p > 0.05), the mesiodistal angulations of the canines in the Group 1 were significantly higher than the study groups (p < 0.05). With treatment, while the mesiodistal angulation of the canines increased in Group 2, it decreased in Group 3 (p < 0.05). On the other hand, the mesiodistal angulation of the central incisors decreased in Group 2 and did not change in Group 3 (p > 0.05). At T1, the mesiodistal angulation of the canines was found to be lower in Group 3 than in Groups 1 and 2, while the angulation of the central incisors was found to be lower in Group 2 compared to Group 1 (p < 0.05). (4) Conclusions: In the orthodontic treatment of MBMLIs, changes in the mesiodistal angulations of the maxillary canine and central incisors should be taken into account for satisfactory outcomes. It was concluded that there should be a tendency to select the space closure method in which normal mesiodistal angulations are obtained in maxillary central incisors for aesthetics and planned incisor position, and also at a low cost.
