Proteomic analysis of extracellular matrices (ECM) of dentoalveolar tissues can provide insights into developmental, pathological, and reparative processes. However, targeted dissection of mineralized tissues, dental cementum (DC), alveolar bone (AB), and dentin (DE), presents technical difficulties. We demonstrate an approach combining EDTA decalcification and laser capture microdissection (LCM), followed by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS), to analyze proteome profiles of these tissues...

Facial asymmetry can be classified into the rolling-dominant type (R-type), translation-dominant type (T-type), yawing-dominant type (Y-type), and atypical type (A-type) based on the distorted skeletal components that cause canting, translation, and yawing of the maxilla and/or mandible. Each facial asymmetry type represents dentoalveolar compensations in three dimensions that correspond to the main skeletal discrepancies. To obtain sufficient surgical correction, it is necessary to analyze the main skeletal discrepancies contributing to the facial asymmetry and then the skeletal-dental relationships in the maxilla and mandible separately...

A clinical problem commonly encountered by the advanced restorative dentist is a requirement to replace missing teeth and the supporting alveolus in areas adjacent to healthy or manageable dentition. A potential solution could utilize a dentoalveolar prosthesis fabricated on two or more implants in the edentulous area. The implant substructure, or framework, may be cast, milled, or selectively laser melted from a variety of metals. A superstructure, or ceramic overlay incorporating a ceramic or composite resin gingival tissue component, is constructed to fit over the implant substructure and luted to the substructure with resin cement...

Craniofacial trauma is common in the pediatric population, with most cases limited to soft tissue and dentoalveolar injury. Although facial fractures are relatively rare in children compared with adults, they are often associated with severe injury and cause significant morbidity and disability. Initial evaluation of a child with facial trauma generally involves stabilizing the patient and identifying any severe concomitant injuries before diagnosing and managing facial injuries. The management of pediatric facial fractures is relatively more conservative than that of adults, and nonsurgical management is preferred when possible to prevent the disruption of future growth and development...

PURPOSE: Aim of the present study was to compare the effects of posterior bite block-vertical pull chin cup (PBB-VPC) and posterior bite block-high pull headgear (PBB-HPH) in the early treatment of anterior open bite. METHODS: This retrospective study was carried out using pretreatment (T1) and posttreatment (T2) lateral cephalometric radiographs of 28 patients treated with either PBB-VPC or PBB-HPH and 14 age-matched control patients with anterior open bite. The treatment changes were evaluated with 20 measurements (7 angular and 13 linear)...

Background and objectives: There is no consensus in the literature regarding which rapid maxillary expansion (RME) design or activation rate benefits the patients the most. Therefore, the primary aim of this systematic review was to see whether there is a difference in the skeletal and dentoalveolar effects of different RME appliances in children and growing adolescents. The secondary aim was to see whether these effects are different when using different activation protocols for these appliances...

An orthodontic appliance in the mouth worsens conditions for its self-cleaning, complicates the teeth care and makes an environment favorable to the soft tooth deposit, in turn, leads to the teeth enamel demineralization. In literature, the majority of works are devoted to the study of the microbial landscape with fixed orthodontic treatment. Despite the obvious relevance, the formation problem of opportunistic and pathogenic microorganisms when treating dentoalveolar anomalies with a removable orthodontic appliance remains understudied...

The aim of the work was to study the structure of dentofacial anomalies in children and adolescents in Sumy city and Sumy oblast, to identify dentoalveolar morphological peculiarities of the occlusion in 10-13 years old patients with class ІІ1 anomalies according to Angle's classification with different types of lower jaw bone growth. A retrospective analysis of 2236 outpatient dental cards of urban and rural patients with orthodontic pathology was conducted. Patients were divided into three age groups: 6-9 years old (early mixed occlusion) - 592 children; 10-13 years old (late mixed occlusion) - 1180 children; over 13 years old (permanent occlusion) - 464 persons; besides 76 patients with class ІІ1 anomalies according to Angle's classification aged 10-13 years were examined...

OBJECTIVE: The dynamic bone-periodontal ligament (PDL)-tooth fibrous joint consists of two adaptive functionally graded interfaces (FGI), the PDL-bone and PDL-cementum that respond to mechanical strain transmitted during mastication. In general, from a materials and mechanics perspective, FGI prevent catastrophic failure during prolonged cyclic loading. This review is a discourse of results gathered from literature to illustrate the dynamic adaptive nature of the fibrous joint in response to physiologic and pathologic simulated functions, and experimental tooth movement...

PURPOSE: To establish cranio-maxillary complex finite element models (FEMs) in cleft lip and palate (CLP) patients with miniplate and tooth-borne anchorage, and to investigate the biomechanical effects on maxillary protraction. METHODS: The protracting process was simulated on FEMs established from a male patient's cone beam CT (CBCT) data to analyze the displacement and stress from different appliances. RESULTS: Four FEMs of unilateral cleft lip and palate (UCLP) or bilateral cleft lip and palate (BCLP) patients' cranio-maxillary complex with MA and TA were established...

AIM: The aim of the present study was to compare the effects of surgical and nonsurgical rapid maxillary expansion (RME) in skeletally mature patients. MATERIALS AND METHODS: Surgically assisted rapid maxillary expansion (SARME) was used in 18 patients (2 males, 16 females) with a mean age of 19.90 years. Two nonsurgical RME groups were constructed to compare the expansion changes of SARME. Eighteen patients in maximum pubertal peak (12 males, 6 females) with a mean age of 13...

Introduction This study describes dentoalveolar and palatal growth during the first months of life. Knowledge concerning this development is essential to avoid unwanted events such as mucosal ulcerations or restriction of growth when cleft-lip and palate (CLP) patients are treated. The results involve the generation of CAD/CAM CLP-feeding plates. Methods Intra-oral impressions from 32 healthy newborns were taken monthly for five months, supplemented by measurements of body weight, length, and occipital-frontal head circumference...

The aim of this study was to describe the treatment of class II malocclusion by sagittal advancement of the alveolar bone in the symphyseal area using an intraoral archwise distractor device and to determine the effects of this method on the dentoalveolar complex. Fifteen patients (10 female, five male) aged 16-20 years with a class II division 2 malocclusion, characterized by mandibular dentoalveolar retrusion and a prominent chin, underwent archwise alveolar distraction in the anterior mandible. Lateral cephalometric radiographs were obtained before distraction (T0), after 6 weeks of consolidation (T1), and after debonding (T2)...

INTRODUCTION: Surgically assisted mandibular arch expansion is an effective treatment modality for alleviating constriction and crowding. However, only mandibular symphyseal osteotomy is recommended for mandibular arch expansion. No relevant studies have compared the biomechanical responses of different corticotomy designs on mandibular expansion. Therefore, the aim of this study was to evaluate the effect of different corticotomy approaches and modes of loading on the expansion of adult mandibles using biomechanics...

INTRODUCTION: The aim of this study was to determine the effects of the leveling of the curve of Spee in subjects treated with preadjusted appliances in different skeletal vertical patterns. METHODS: The study sample consisted of 90 white patients (39 male, 51 female; age, 19 years 4 months ± 1 year 9 months), with a curve of Spee of 2 mm or greater before treatment. They were categorized into 3 groups: low-angle group (30 subjects; 12 male, 18 female; age, 19 years 1 month ± 1 year 4 months), normal-angle group (30 subjects; 14 male, 16 female; age, 19 years 6 months ± 2 years 1 month), and high-angle group (30 subjects; 13 male, 17 female; age, 19 years 7 months ± 1 year 5 months) by their vertical facial types...
