Permanent central incisor impaction is very rare, and causes of impaction include adjacent supernumerary teeth, odontoma, and trauma. Surgical repositioning is a treatment option for teeth with ectopic eruption pathways. In this case report, an inverted developing maxillary central incisor was surgically repositioned at the initial stage of root development. Three dimensional (3D) virtual images were acquired using computed tomography, and a replica was produced by LCD-based masked stereolithography 3D printing. A resin for 3D printing was approved as a medical device and used as a 3D printing replica. Further, 3D technology has been found to be useful for successful tooth repositioning surgery.

Supernumerary teeth are a relatively frequent disorder of odontogenesis characterized by an excess number of teeth. Mesiodens is the most common type of supernumerary teeth found in the premaxilla between the two central incisors. They can be supplemental (resembling natural teeth), conical, tuberculate, or molariform. We present a rare case of 41 year old male patient who presented with bilateral mesiodens.

3D Printing Technology

Defects in the oral and maxillofacial (OMF) complex may lead to functional and esthetic impairment, aspiration, speech difficulty, and reduced quality of life. Reconstruction of such defects is considered one of the most challenging procedures in head and neck surgery. Transfer of different auto-grafts is still considered as the “gold standard” of regenerative and reconstructive procedures for OMF defects. However, harvesting of these grafts can lead to many complications including donor-site morbidity, extending of surgical time, incomplete healing of the donor site and others. Three-dimensional (3D) printing technology is an innovative technique that allows the fabrication of personalized implants and scaffolds that fit the precise anatomy of an individual’s defect and, therefore, has attracted significant attention during the last few decades, especially among head and neck surgeons. Here we discuss the most relevant applications of the 3D printing technology in the oral and maxillofacial surgery field. We further show different clinical examples of patients who were treated at our institute using the 3D technology and discuss the indications, different technologies, complications, and their clinical outcomes. We demonstrate that 3D technology may provide a powerful tool used for reconstruction of various OMF defects, enabling optimal clinical results in the suitable cases.

Tooth Structure

Teeth with calcific metamorphosis pose a challenge to the endodontist in achieving proper access, identification, and debridement of the root canal. With the conventional technique, radiographs and bur orientation have dictated the access cavity preparation, which leads to the removal of more sound tooth structure and iatrogenic errors. To overcome these issues, the recent diagnostic imaging techniques such as cone beam computed tomography followed by three-dimensional fabrication of template have been proposed, which aid the clinician to accurately locate and negotiate the obliterated canal. The present case report describes the importance of conservative access cavity preparation with the use of the guided endodontic technique for the treatment of calcified canals in the maxillary central incisor.

Introduction: The maxillary anterior region is becoming a major concern due to its aesthetic relevance. The buccal bone thickness is important for implant placement, orthodontic treatment and restorative treatment. Objective: To assess the thickness of alveolar bone in the maxillary central incisor using cone beam computed tomography (CBCT). Methods: A cross-sectional observational study was conducted at Department of Dental Surgery, Bir Hospital where CBCT of 53 samples from July 2019 till December 2019, the archived CBCT images was assessed retrospectively. The thickness of the labial bone in a direction perpendicular to the outer surface of the tooth root was measured at a distance of 2 mm from the cementoenamel junction (CEJ). The measurement was taken thrice and the mean measurement was considered. Results: The labial alveolar bone thickness in maxillary central incisor was found to be 0.55±0.27 mm at a distance of 2 mm from the CEJ. Only 2 (3.8%) of the samples had an alveolar thickness of >1 mm. No statistically significant difference was found with respect to gender and age. Conclusion: The average thickness of the labial alveolar bone in maxillary central incisor using cone beam computed tomography was found to be thin.

ABSTRACT Aim The purpose of this report is to present a case of endodontic management of a dilacerated maxillary central incisor fused to supernumerary tooth unusually appearing as a labial tubercle using cone beam computed tomography (CBCT) as a diagnostic aid. Background Anterior teeth are commonly encountered with aberrant anatomical variations in the crown, number of roots, and root canals. Fusion is an infrequent developmental abnormality in shape of the tooth caused by the union of two adjacent tooth germs. A complete knowledge of such complex anatomies is mandatory for a successful root canal treatment. It highlights the endodontic and restorative approach in the functional and esthetic rehabilitation of the involved tooth. Case report Three-dimensional imaging using CBCT was used in this case to differentiate single labial canal and palatal C-shaped canal. The endodontic treatment was performed with the aid of dental operating microscope, and the root canals were obturated with a combination of single cone, carrier based, and cold flowable gutta-percha obturation system. The tooth remained asymptomatic without reinfection and symptoms of failure for 18 months. Conclusion Cone beam computed tomography is indispensable in treatment planning for cases where the radiographs cannot reveal useful information regarding the root canal shape. Postobturation CBCT has helped in avoiding further retreatment of the tooth, which otherwise is a challenging task. Clinical significance The use of sophisticated equipment, such as dental operating microscope and CBCT has helped in accurate diagnosis and treatment planning of fused central incisor respectively.
