“…21,22 MSE is a well-documented type of MARPE that exploits the concept of producing a posterior force vector by the posterior positioning of jackscrew and a more stable anchorage by the bicortical engagement of its four mini-screws, which produces a parallel pattern of skeletal expansion in the horizontal plane. [23][24][25][26][27] Traditionally, MSE appliances are manufactured on stone models. In a recent publication, digital planning of MSE based on a patient's CBCT image has been proposed.…”

The miniscrew-assisted rapid palatal expansion approach has given new opportunities for the treatment of maxilla transverse deficiency by providing an alternative to the surgical approach for adult patients. However, the presence of a thin palatal bone can compromise the success of such approach. Recently, the digital planning of the miniscrew-assisted appliances has offered unique advantages in terms of safety and accuracy of the overall process. The aim of this study is to describe the digital planning and MSE fabrication with cad-cam technology using 6 mini-screws in cases with a palatal bone thickness of less than 2.5 mm.

“…Recently, in order to avoid the potential risk of damaging anatomical structures, Cantarella et al [36] suggested that the deployment of 3D virtual surgical planning using digital data might be advantageous prior to undertaking MSE. Elkenawy et al [37] were also interested in the biomechanics of MSE. In their study, they noted that over half of approx.…”

The concept of palatal expansion can be viewed as an anachronism since the delivery and scope of this clinical technique has changed dramatically over the past few decades. Indeed, since the palatal complex does not exist in isolation, clinicians ought to be cognizant of how palatal expansion affects contiguous midfacial structures. Because of this structural arrangement, surgical and non-surgical palatal expansion can have clinical consequences on the dentoalveolar structures, which are dependent on bony remodeling of the maxillo-palatine complex. In addition, it can also be suggested that morphologic alterations of the maxillary air sinus might lead to functional and clinical improvements of inflammatory changes associated with rhinosinusitis. Furthermore, enhancements in the nasal airway could affect a host of other conditions, including nasal breathing and obstructive sleep apnea, etc. Therefore, the aim of this chapter is to review the effects of midfacial expansion techniques on contiguous structures, including the paranasal sinuses.

“…Micro-implant-assisted expanders have proved significant effects on the mid-face, with a degree of asymmetry [49]. On non-growing patients, CBCT images showed a statistically significant difference between the average magnitude of the total expansion of 4.98 mm at the anterior nasal spine and the average of 4.77 mm at the posterior nasal spine.…”

The aim of this study was to review the literature and evaluate the failure rates and factors that affect the stability and success of temporary anchorage devices (TADs) used as orthodontic anchorage. Data was collected from electronic databases: MEDLINE database and Google Scholar. Four combinations of term were used as keywords: “micro-implant”, “mini-implant”, “mini-screw”, and “orthodontics”. The following selection criteria were used to select appropriate articles: articles on implants and screws used as orthodontic anchorage, published in English, with both prospective and retrospective clinical and experimental investigations. The search provided 209 abstracts about TADs used as anchorage. After reading and applying the selection criteria, 66 articles were included in the study. The data obtained were divided into two topics: which factors affected TAD success rate and to what degree and in how many articles they were quoted. Clinical factors were divided into three main groups: patient-related, implant related, and management-related factors. Although all articles included in this meta-analysis reported success rates of greater than 80 percent, the factors determining success rates were inconsistent between the studies analyzed and this made conclusions difficult.
