The last few decades have witnessed an evolution in orthodontics and bone remodeling to meet contemporary aesthetic and therapeutic needs. Over the past century, various methods have been used and investigated, including invasive surgical and non-surgical methods. However, in certain circumstances, significant challenges may arise that can lead to adverse postherpetic outcomes. To minimize patient injury and destruction, a variety of surgical instruments and handpieces are used during corticotom

The purpose of this article is to present a computer designed and 3D-printed metal device, which was used for the surgical exposure and orthodontic treatment of maxillary palatally impacted canines. In two cases which presented a palatally impacted canine, a Cone-Beam Computed Tomography (CBCT) was acquired and an intraoral scanning was performed, to determine the exact location of the canine. Based on a digital model, a device leaning on the teeth and mucosa was designed to serve as a guiding tool for the oral surgeon to expose the crown of the canine and help the orthodontist to provide proper traction. The device was then 3D-printed in biocompatible dental alloy and placed in the patients’ mouth. After the surgical exposure of the canine’s crown in both cases, a gold chain apparatus was bonded on and it was mounted on the metal projection of the device through an elastic chain. Within 3 months of traction, the crown of the canines appeared in the patients’ palate to the exact location that was predicted and guided. A 3D-designed and manufactured metal device, with information acquired by CBCT and intraoral scanning, can be used for the exposure and traction of palatally impacted canines.

The increased number of adults seeking orthodontic treatment has led to the need for faster results as social limitations arise with the use of fixed or even removable appliances. Corticotomy-assisted orthodontic treatment (CAOT) has been proposed as a technique that accelerates tooth movement and leads to a substantial reduction in treatment time. This review was conducted by searching four databases for original articles about CAOT, review articles and articles about alternative techniques and periodontal effects up to 31 December 2022. The aim of the review was to present the historical and biological background of CAOT, the description of the technique and some alternative and less invasive techniques that have been proposed. Indications, contraindications and periodontal side effects are also discussed.

The article presents a case of bimaxillary dentoalveolar protrusion treated by distalizing the upper and lower teeth, using anchorage from mini implants. A 16-year-old male patient presented with severe upper and lower incisor proclination with protruding lips and a convex profile, with a background of bimaxillary dentoalveolar protrusion. Instead of having four premolars extracted, retraction of the dentition was decided with absolute anchorage, provided by mini implants. In order to carry out the procedure in one stage, four mini-implants were inserted as close to the root of the 1st molars as possible. Implementation was facilitated by a surgical template which was created on a digital model and then 3D printed. Accurate placement was achieved and the case was successfully treated by significant uprighting of the incisors and retraction of the anterior dentition, closing the spaces in the upper and lower arch. Facial aesthetics were also improved. A digitally designed surgical guide was utilized in this case of bimaxillary dentoalveolar protrusion in order to facilitate the accurate placement of the mini implants which were used for a one-stage retraction of the dentition.
