Physiological natural tooth displacement under occlusal loading can influence intraoral occlusal contacts. However, gypsum casts and digital scans cannot simulate the physiological tooth displacement under occlusal loading. The occlusal design of the implant-supported crowns has been based mainly on the experience of dental laboratory technicians, lacking accuracy and individualization. Therefore, a digital technique that considers physiological tooth displacement is presented to design the occlusion of implant-supported single crowns.

Clear aligners offer aesthetic and comfort advantages in orthodontics, yet their ability to deliver effective forces relies heavily on empirical judgment or large-scale optical scanning, lacking real-time quantitative evaluation. Integrating pressure sensors into aligners is a promising solution, but challenges in miniaturization, multi-dimensional sensing, measurement accuracy, and biocompatibility hinder clinical application. Here, an all-in-one Orthodontic Force Acquisition System (OFAS) is presented that enables real-time, 3D force monitoring using a cross-shaped iontronic sensing array and an origami-inspired, wireless battery-free readout circuit miniaturized for single-tooth placement.

Introduction: Juvenile ossifying fibroma (JOF) is a rare, benign, fibro-osseous lesion characterized by aggressive growth and potential for recurrence. It primarily affects children and adolescents, with two histopathological subtypes: trabecular JOF (TrJOF) and psammomatoid JOF (PsJOF). TrJOF typically presents in the jaws of younger individuals, often before the age of 15.

Background: Odontomas are odontogenic tumors located in the jawbone, referred to by the World Health Organization (WHO) as hamartomatous (Greek hamartion - a bodily defect) developmental malformations. The term was first used by Brock in 1866 to refer to every odontogenic tumor. Today an odontoma is believed to be a congenital malformation of dental hard tissues.

Objective: To develop a technique for 3D analysis of the upper part of the cervical spine, to study possible correlations with temporomandibular joint (TMJ) parameters in patients with signs of its dysfunction.
Material And Methods: The data from cone beam computed tomography (CBCT) of the heads of 92 patients who sought treatment for TMJ dysfunction (49 people), comprehensive dental treatment (28 people), and orthognathic surgical treatment (15 people) were analyzed. Patients with signs of TMJ dysfunction were divided into 2 subgroups: 1 - patients with asymmetric narrowing of the articular gap (24 people); 2 - patients with symmetrical narrowing (25 people).

Objective: To conduct a comparative analysis of the aesthetic results of treatment of patients with gingival recession of RD class I and II according to Miller using collagen matrices and connective tissue transplant (CTT).
Material And Methods: The study included 25 patients with grade I and II RD in the area of 107 teeth on the upper and lower jaws. The patients were divided into 4 groups: Mucoderm (=28), Fibro-Gide (=22), FibroMATRIX (=23) and CTT as controls (=34).
