Introduction: Autogenous transplantation of a natural tooth to another site has significant advantages over dental implants, particularly in cases of agenesis, accidental tooth loss, or poor prognosis for the maintenance of tooth function.
Methods: This report describes a case of autogenous premolar transplantation into an artificial socket in the site of a missing maxillary lateral incisor in a 13-year-old girl. Clinical examination and radiography revealed tooth agenesis (#4, #10, #13, and #20) and microdontia (#7). The occlusion and skeletal maxillomandibular relations were normal.
Results: Tooth #29 was chosen for transplantation into the site of tooth #10 because of its size, stage of root formation, and possible closure of the spaces created by agenesis.
Conclusions: Autogenous transplantation is a feasible alternative to dental implants in cases of tooth agenesis or tooth loss because of trauma. Autotransplantation was indicated in this case because it ensures the natural (facial) growth of the alveolar process and preserves the function of periodontal tissues. A multidisciplinary approach (ie, combining techniques from different dental specialties) was important for treatment success. Clinical and radiographic follow-up confirmed that the transplanted premolar was esthetically comparable with the lateral incisor and that root development and pulp canal obliteration were complete.

Background: Hybrid Odontogenic Tumors (HOT) are defined by the presence of two or more independent odontogenic tumors that originate from and affect the same maxillofacial site.
Methods: The present study is the first case report of a mandibular HOT consisting of Ameloblastoma, Calcifying Epithelial Odontogenic Tumor, and Ameloblastic Fibroma.
Case Report: A 37-year-old otherwise healthy male presented with the chief complaint of swelling in the right mandibular body.

The injection moulding technique (IMT) is a minimally invasive restorative treatment. This technique enables the application of thin, flowable composite layers into a stable, transparent silicone index that serves as a mould. Due to the fluid properties of the composite, it efficiently fills the silicone tray and seamlessly integrates with the tooth structure, often obviating tooth preparation and preserving overall tooth integrity.

Objective: The effect of different attachment positions on torque control during the labialization of maxillary lateral incisors with clear aligners was evaluated using finite element analysis.
Methods: Anatomical data acquired through cone-beam computed tomography, combined with the design of 0.625-mm-thick aligners and horizontal attachments, were integrated into the software.
The effects of maxillary incisor positions and chin prominences on the perception of lateral smiling profile attractiveness among orthodontists and laypersons.

Department of Orthodontics, Chulalongkorn University, Bangkok, Thailand.
Objective: To evaluate the ideal anteroposterior position of incisors in lateral smiling profiles with different chin prominences and to relate these positions to nose and chin landmarks based on the perceptions of orthodontists and laypersons.
Methods: A lateral smiling profile image of a female subject was adjusted to create five levels of chin prominence (-6, -3, 0, +3, +6 mm). For each level, the anteroposterior positions of the maxillary incisors were adjusted across five positions (-4, -2, 0, +2, +4 mm).
