Special Issue Information

Dear Colleagues,

The aim of this Special Issue is focusing on the latest research in and applications of skeletal anchorage in orthodontics in combination with the use of digital planned devices. Modern orthodontics have realized notable advantages from the combination of these two modern applications, in particular, in the upper arch, extending the limits of orthodontists’ capabilities. This Special Issue will also consider submissions focused on the use of biomaterials to enhance orthodontic treatments and results.

The current study aimed to perceive and estimate the distribution of stress generated by the forces on the maxillary anterior teeth during orthodontic retraction using the bilateral mini screw implant. Finite element models were generated from the three-dimensional (3D) reconstruction of the maxillary arch via cone–beam computed tomography (CBCT). These models imitate the retraction of maxillary anterior teeth with the mini screw placed as the skeletal anchorage. The titanium mini screw of 1.3 mm × 8 mm dimension was placed at a height of 9 mm between the first molar and second premolar on both sides of the maxilla. A nickel titanium (NiTi) coil spring of 9 mm length was attached from the mini screw implant to the power arm which generated a force of 250 gm/side. Two different power arms were placed between the lateral incisor and canine at a height of 4 mm (group 1) and 8 mm (group 2), respectively. There were no significant differences observed when the stress values were compared to the left side and the right side in group 1 with a power arm of 4 mm. In group 2, the stresses around the lateral incisors were found to be on the higher side when compared with the central incisors and canines. The length of the power arm shows no significant difference in stress distribution pattern on the left and right sides except for stresses moving from the canine region to the lateral incisor region with the increase in power arm height.

Digital Planning Technique for Surgical Guides for Prosthetic Implants before Orthodontic Treatment

Background: The use of digitalization allows clinicians to plan the position of dental implants in orthodontic patients treated with aligners in the beginning of their orthodontic treatment, instead of waiting until the end of orthodontic treatment, integrating implant restorations with orthodontic biomechanics. Aim: The aim of this case report is to describe a digital workflow for aligner treatment supported by implants, in which implants are placed at the beginning of the treatment and support the orthodontic treatment. Materials and Methods: Digital planning for orthodontic treatment with clear aligners and the preparation of surgical guides for implant surgery before orthodontic treatment are used to solve two multidisciplinary cases. Cone-beam computed tomography (CBCT) and virtual dental impressions are used for the virtual planning. Successively, a surgical guide for implant placement and aligners are used in the treatment plan. Results: The digital orthodontic setup with the integration of the root position allows the clinician to plan the position of dental implants on the final occlusion. The placement of the implant before the start of the orthodontic treatment allows the implants to be used as skeletal anchorage, thereby helping the orthodontic biomechanics. Conclusions: This study describes how to perform a digital workflow with orthodontic virtual planning and the design of surgical guides for implant placement. This technique is potentially promising for complex orthodontic cases. Full article

Case Report

Introduction: Class II growing patients can be successfully treated with the Herbst appliance, nevertheless this therapy generally produces side effects, such as upper incisors retroclination and lower incisors proclination, which eventually could reduce mandibular forward advancement. Treatment objectives: The purpose of this article is to show a treatment of class II malocclusion with crowding in both arches by a skeletally reinforced Herbst appliance. Treatment description: Two miniscrews were applied in the lower arch to control lower incisors proclination and in the upper arch an Hybrid palatal expander was used. Results: the correction of the severe class II malocclusion was obtained with mandibular advancement, avoiding lower incisors proclination with control also of the upper incisors. Upper crowding with lack of space for upper canine alignment was corrected. Conclusions: Upper and lower miniscrews worked successfully as anchorage for the entire treatment. Full article

Background: The demand for interdisciplinary orthodontic treatment has increased significantly in the past few years, especially in adult patients. This kind of treatment requires careful clinical management, as consequence of the possible complications and limits related to adult age. However, the use of skeletal anchorage and three-dimensional (3D) digital technology has deeply revolutionised diagnostic planning and treatment strategies. Methods: A fully digital approach to the treatment of a Class II patient with a gummy smile and mandibular deficiency and deviation, consisting of initial surgery followed by the use of aligners and skeletal anchorage, is described. Results: The 3D, fully digital pre-evaluation enabled clinicians to accurately and reliably plan the surgical procedure and subsequent orthodontics, including the individualised positioning of stabilisation plates and a splint for maxillary and chin surgical movements. This allowed for the improvement of the patient’s facial aesthetics and dental occlusion without the use of visible orthodontic appliances or the occurrence of pre-surgical aesthetic worsening. Conclusions: This approach could be very effective for adult patients seeking aesthetic treatment options for facial and dental aesthetic improvement. Full article

Orthodontic anchorage is a necessity for every treatment and must be carefully evaluated by the orthodontist. It is defined as the resistance to unwanted dental movement of a tooth or a number of teeth by using different techniques. The purpose of the present paper is to highlight the subperiosteal anchorage applied to orthodontics; this technique has been debated in the literature and the purpose here is to summarize the fields of application. During the first check of previous literature 548 results were found, which have been reduced to 19 selected papers after application of the inclusion criteria and the elimination of duplicates. Multiple electronic databases were searched from 1 January 1995 to 31 December 2020 in order to identify papers eligible for current review. The data obtained by this review underlined the versatility of onplants used as absolute anchorage during orthodontic treatments, the advantages and disadvantages, the biomechanical properties and survival rates, and the clinical procedure. Further clinical studies and research are required to explore other kinds of application and to state specific guidelines; however, this study represents an update and a starting point for clinicians who want to use these devices and for further improvement of the technique.
