Evaluation of occlusal force in Class II subdivision malocclusion.

Background: Class II subdivision is a malocclusion characterized by dental and functional asymmetry that is difficult to manage. Impaired muscle function can result in asymmetrical growth, leading to occlusal instability.

Objective(s): The study aimed to assess occlusal force in patients with Class II subdivision malocclusion using Innobyte.

Craniofacial morphology in Obstructive Sleep Apnea patients.

Background: To evaluate the correlation between cephalometric skeletal parameters and Obstructive Sleep Apnea syndrome (OSAs) severity, in adult patients with OSAs.

Skeletal and dental effects of function-generating bite appliance compared to rapid palatal expander and untreated controls.

Introduction: Maxillary expansion is a fundamental interceptive orthodontic treatment, which can be achieved through either a rapid expansion protocol or functional devices. However, no data exist about the efficacy of functional devices in achieving skeletal expansion. Therefore, the aim of this study was to compare the effects of the rapid palatal expander (RPE) and the function-generating bite type M (FGB-M) on the transversal dimension of the maxilla, and on the maxillary and mandibular dental arch width.

Methods: Sixty-four patients (8 women and 56 men, mean age 52.

Single ultra-short implant rehabilitation of posterior atrophic maxillae with 5 years follow-up.

Rehabilitation of edentulous ridges, in some cases, can represent a challange for both the oral surgeon and the patient. After teeth loss, posterior sectors of the maxilla can shrink because of both the crestal resorption and sinus pneumatization. The implant placement in such cases requires invasive procedures of sinus lift and bone augmentation.

Twenty eight months marginal bone level follow-up of an immediate post-extractive implant with immediate definitive loading.

Objective: The aim of this case report was to show the marginal bone level (MBL) variation, after 28 months, around an aesthetic post-extraction implant immediate loading positioned in a 46-years-old woman.

Material And Methods: After a careful evaluation of the X-rays and CBCT images, a 4×13 conical implant was placed in seat 21 after the atraumatic extraction of the fractured element and the management of the infected area. Correct primary stability (torque 70 Ncm) was obtained by inserting the implant in a palatal position with respect to the alveolus.

Changes in implant stability using different site preparation techniques: Osseodensification drills versus piezoelectric surgery. A multi-center prospective randomized controlled clinical trial.

Introduction: Implant stability is influenced by bone density, implant design, and site preparation characteristics. Piezoelectric implant site preparation (PISP) has been demonstrated to improve secondary stability compared with conventional drilling techniques. Osseodensification drills (OD) have been recently introduced to enhance both bone density and implant secondary stability.

The aim of this retrospective study was to compare the efficiency of two biologically oriented devices in achieving maxillary expansion: Rapid Palatal Expander (RPE) and Nitanium Palatal Expander-2 (NPE-2). Thirty-six subjects, divided in two equal groups, were included in this study. Maxillary dental arches were scanned using Trios 3 shape, in order to perform a digital analysis of 3D models.

Long-term effect on adenoid dimensions and craniocervical angulation after maxillary expansion with fixed or functional appliances.

Background: Maxillary expansion is a common orthodontic procedure that could have a positive effect also on airway patency. The aim of the present study was to evaluate the long-term effects of rapid maxillary expansion (RME) on nasopharyngeal area and cranio-cervical angulation in growing patients, compared to controls treated with a function-generating bite appliance (FGB).

Material And Methods: Sixty patients aged 6-14 consecutively treated with RME or FGB were selected retrospectively and divided into two groups.

Morphometric analysis of sella turcica in growing patients: an observational study on shape and dimensions in different sagittal craniofacial patterns.

The aim of this study was to evaluate the differences in sella dimensions and shape between growing patients with Class I, Class II, and Class III skeletal malocclusions, evaluated through morphometric analysis. Seventy-eight subjects aged between 9 and 13 years were selected and assigned to either the Class I, Class II, or Class III groups according to the measured ANB angle (the angle between the Nasion, skeletal A-point and skeletal B-point). Six landmarks were digitised to outline the shape of the sella turcica.

Non-surgical Treatment of Condylar Fracture in an 11-Year-Old Patient: a Case Report.

Background: Mandibular condylar fractures commonly occur after trauma and account for 25 to 35% of all mandibular fractures; its appropriate therapy still remains a point of controversy in children.

Effects of crown movement on periodontal biotype: a digital analysis.

Orthodontic treatment has important correlations with periodontal changes. Various mechanical and biological factors are involved in determining such changes, but anatomical and morphological variables, generally addressed as periodontal biotype, play a key role. In measurement of such modifications, digital and non-contact reverse engineering technologies may be of tremendous advantage.

Swallowing and Temporomandibular Disorders in Adults.

Introduction: Temporomandibular disease (TMD) etiology is multifactorial and is related to many perpetuating, predisposing, and initiating factors. The daytime parafunctions may have an important role in TMD pathogenesis. The most frequent parafunctions analyzed were the static parafunction (ie, clenching) and the dynamic parafunction (ie, grinding).

Cephalometric evaluation of tongue position and airway remodelling in children treated with swallowing occlusal contact intercept appliance (S.O.C.I.A.).

Introduction: Facial growth changes the position of the jaws (in particular vertical position of the maxilla and antero-posterior position of the mandible) and may, in turn, modify the position of the tongue and the hyoid bone, thus, generating modifications of the upper airway space. In the present paper, effects on upper airway space and tongue position of a new functional appliance, the swallowing occlusal contact intercept appliance (SOCIA) have been investigated.

Materials And Methods: Retrospective cephaolmetric study of twenty-four children (mean age 9.
