Abstract

In recent years, many researchers and clinicians found interest in regenerative medicine using induced pluripotent stem cells (iPSCs) with biomaterials due to their pluripotency, which is able to differentiate into any type of cells without human embryo, which of use is ethically controversial. However, there are limitations to make iPSCs from adult somatic cells due to their low stemness and donor site morbidity. Recently, to overcome above drawbacks, dental tissue-derived iPSCs have been highlighted as a type of alternative sources for their high stemness, easy gathering, and their complex (ectomesenchymal) origin, which easily differentiate them to various cell types for nerve, vessel, and other dental tissue regeneration. In other part, utilizing biomaterials for regenerative medicine using cell is recently highlighted because they can modulate cell adhesion, proliferation and (de)differentiation. Therefore, this paper will convey the overview of advantages and drawbacks of dental tissue-derived iPSCs and their future application with biomaterials.

Abstract

The term, ‘crossed occlusion’ implies clinical situation in which the residual teeth in one arch have no contact with those in the antagonistic arch, resulting in the collapse of occlusal vertical dimension. The treatment goal of this pathologic condition is restoration of the collapsed vertical dimension and stabilization of abnormal mandibular position. Previously, konus removable prostheses or tooth supported overdentures were suggested to solve crossed occlusion. Nowadays, dental implants have been used for definitive support to solve this problem. In this case report, a 65 years old female patient had a crossed occlusion, in which the maxillary posterior residual teeth and mandibular anterior residual teeth cross. Interim removable and fixed dental prostheses were used to confirm the proper vertical and horizontal jaw relation. After that, the mandibular posterior edentulous region was restored with implant-supported fixed dental prostheses. Computer tomography guided implant surgery was performed according to the concept of the restoration-driven implant placement. The maxillary anterior edentulous region was restored with Kennedy class IV removable prosthesis, considering the patient’s economic status. The patient’s jaw position and prostheses have been well maintained at the follow-up after 6 months of definitive restoration. The antero-posterior crossed occlusion problems appeared to be effectively solved with the combination of removable in one arch and implant-supported fixed prostheses in the other.

Abstract

Orthodontic treatment with premolar extraction is usually performed to correct bialveolar protrusion. These methods require the use of stiff rectangular working archwire which requires lengthy alignment and leveling before insertion. In this case report, interproximal reproximation was performed instead of extraction. To establish clearance between the archwire and resin domes fixing the archwire, an archwire was inserted into a water-soluble tube before fabricating resin domes. This tube is solved away by the saliva. During fabrication of resin domes, the archwire was deflected intentionally reflecting the displacement of teeth from their ideal position. This can be called as deflection-based bonding (DBB) technique. DBB is different from conventional method of positioning the brackets on its ideal position and then inserting an archwire to align the brackets. Because the orthodontic force of the archwire comes from its deflection from passive configuration, deflecting an archwire as needed can move the teeth more predictably than just bonding brackets on its ideal position. Also, areas with good alignment before orthodontic treatment can be maintained simply by not deflecting the archwire during bonding in these areas. After initial alignment, interproximal reproximation was performed to create 4.8 mm space in the maxillary arch and 4.2 mm space in the mandibular arch. These spaces were closed using orthodontic mini-implant anchorage thus retracting the maxillary incisors 4 mm posteriorly accompanied with 0.7 mm and 0.3 mm distal movement of right and left molars. By using interproximal reproximation and water-soluble tube with DBB, mild bialveolar protrusion was successfully treated without extraction.

Abstract

Cleft lip and palate is the most common teratologic condition of oromaxillofacial units, probably associated with genetic and environmental causes. The goal of cleft surgery is to optimize facial esthetics and stomatognathic function while minimizing growth disturbances from surgical intervention. In this article, the author suggests the recent surgical strategies that minimize cleft nasal deformity and midfacial skeletal constriction. From the author’s surgical experiences and literature reviews, only considerate surgeries would achieve functional improvement and facial esthetics in patients with cleft lip and palate.

Abstract

Maxillary growth is hindered by the restricting pressure from the scar tissue formed after lip closure and palate closure surgeries of the cleft. Therefore, the anteroposterior skeletal relationship of both jaws exacerbates as patient grows. Conventional facemask treatment is valuable for dentoalveolar compensatory treatment and for very mild maxillary hypoplasia. To achieve further maxillary protraction, bone-anchored facemask or bone-anchored maxillary protraction can be attempted. For moderate maxillary hypoplasia, surgical orthodontic treatment after growth completion can be an efficient treatment reducing uncontrollable problems. For moderate to severe maxillary hypoplasia, distraction osteogenesis (DO) can be used alone or with later surgical orthodontic treatment. To compensate the severe relapse after DO, overcorrection and bone plate placement after DO are recommended. In case of hypernasality, maxillary anterior segmental distraction osteogenesis can be chosen to prevent exacerbation of the hypernasality.
