Adjunctive orthodontic management of a missing upper right central incisor in a 12-year-old male using a fixed orthodontic appliance

This article presents a successful orthodontic management of a 12-year-old male using a fixed orthodontic appliance (straight wire technique). His orthodontic treatment was hinged on creating enough space to accept an artificial tooth, correcting the horizontal and vertical relationships of the upper incisors to the lower and the midline shift. Ultimately, an esthetic smile was achieved; function and self-esteem were improved when the artificial tooth was finally fixed.

FABRICATION OF UNILATERAL OVER DENTURE WITH COMBINATION HORIZONTAL RETENTION AND VERTICAL ATTACHMENT (LABORATORY PROCEDURES)

Background: Currently, there is a lot of design attachment, and every design has a different laboratory procedure. One of them is retention combination horizontal and vertical synchronization. Purpose: to know the process of making a unilateral overdenture with combination horizontal and vertical attachment (laboratory procedure). Reviews: Overdenture is artificial tooth receives support and the retention of one or more teeth an abutment or receives the support of an implant. Attachment is a connector owned two or more parts. One part connected with a root, teeth, or implant while the other part connected to protesa. Unilateral over denture is artificial tooth some off who just made was on the side of the jaw just. Conclusion: The manufacture of unilateral overdenture retention combination with horizontal and vertical synchronization attachment in the laboratory has many steps.

Extracellular Matrix Induces Periodontal Ligament Reconstruction In Vivo

One of the problems in dental implant treatment is the lack of periodontal ligament (PDL), which supports teeth, prevents infection, and transduces sensations such as chewiness. The objective of the present study was to develop a decellularized PDL for supporting an artificial tooth. To this end, we prepared mouse decellularized mandible bone with a PDL matrix by high hydrostatic pressure and DNase and detergent treatments and evaluated its reconstruction in vivo. After tooth extraction, the decellularized mandible bone with PDL matrix was implanted under the subrenal capsule in rat and observed that host cells migrated into the matrix and oriented along the PDL collagen fibers. The extracted decellularized tooth and de- and re-calcified teeth, which was used as an artificial tooth model, were re-inserted into the decellularized mandible bone and implanted under the subrenal capsule in rat. The reconstructed PDL matrix for the extracted decellularized tooth resembled the decellularized mandible bone without tooth extraction. This demonstrates that decellularized PDL matrix can reconstruct PDL tissue by controlling host cell migration, which could serve as a novel periodontal treatment approach.
