Raportim rasti: krahasimi i herbst tradicional dhe herbst të fiksuar mbi minivida
No full textClass II malocclusion is one of the most common orthodontic issues, often treated with the Herbst appliance. This report presents a clinical comparison between the traditional Herbst appliance and the Herbst appliance fixed on miniscrews (TAD - Temporary Anchorage Devices). The cases include a 12-year-old female patient treated with the traditional Herbst appliance and a 15-year-old male patient treated with the Herbst appliance fixed on miniscrews. The results showed that both techniques are effective in correcting Class II malocclusion, with significant improvement in overjet, facial profile, and dento-skeletal relationships. However, the Herbst appliance on miniscrews offered greater stability, minimal relapse, and improved hygienic management, while reducing initial discomfort. In conclusion, the Herbst appliance on miniscrews presents an advanced option for cases requiring more complex skeletal anchorage.Malokluzioni i klasës II është një nga problematikat më të zakonshme në ortodonci, shpesh trajtuar me aparatin Herbst. Ky raport paraqet një krahasim klinik midis Herbst-it tradicional dhe Herbst-it të fik-suar mbi minivida (TAD - Temporary Anchorage Devices). Rastet përfshijnë një paciente 12vjeçare me Herbst tradicional dhe një pacient 15-vjeçar me Herbst mbi minivida. Rezultatet treguan se të dyja teknikat janë efektive në korrigjimin e malokluzionit të klasës II, me përmirësim të ndjeshëm në overjet, profilin facial dhe marrëdhëniet dento-skeletore. Megjithatë, Herbst mbi minivida ofroi stabilitet më të lartë, relaps minimal dhe menaxhim më të mirë higjienik, duke reduktuar diskomfortin fillestar. Në përfundim, Herbst mbi minivida paraqet një opsion të avancuar për raste me kërkesa më komplekse të ankorimit skeletor.

'n Vergelyking van die Herbst- en Gesellmetingsinstrumente vir die evaluering van kleuters se ontwikkelingsvlakke
No full textAfrikaans: Jaarliks is daar 'n groot aantal swart skoolbeginners wat nie sub
A. slaag nie. Dit kan toegeskryf word aan die feit dat baie van
die skoolbeginners nie die ontwikkelingstake - wat onderliggend
is aan skoolgereedheid - bemeester het nie. Volgens Herbst
( 1989) ondervind Vrystaatse Sotho-skoolbeginners veral probleme
met voorgrond/agtergrondwaarneming, vormkonstantheid, posisie in
die ruimte, ruimtelike verhoudings, numeriese en kleurkonsepte,
rigtingsin, en toon ook gebrekkige fynmotoriese vaardighede,
asook emosionele onrypheid vir die skoolsi tuasie. Di t is dus
belangrik om die ontwikkelingsvlakke van die kinders te evalueer
ten einde die probleemareas so vroeg as moontlik op te spoor.
Die Herbstinstrument is ontwikkel om spesifieke ontwikkelingsprobleme
wat Sotho-kleuters ondervind, te evalueer. 'n
Validering van die meetinstrument is gedoen deur 'n vergelyking
met die Gesellmeetinstrument wat 'n wyd erkende en gebruikte ontwikkelingsmeetinstrument
is. Ui t die validering het di t geblyk
dat die Herbstmeetinstrument al die konsepte, behalwe die taalkonsep,
ondervang. Die subtoetse wat op taalkonsep betrekking
het in die Gesellmeetinstrument, het egter die kultuurbillikheid
van die meetinstrument benadeel. Hierdie probleem is grootliks
deur die Herbstmeetinstrument ui tgeskakel, maar tersel fdertyd
bestaan daar steeds 'n behoefte aan 'n meetinstrument waarmee 'n meer kultuurbillike evaluering van die taalvermoe van die Sotho-kleuter gedoen kan word. Daar kan dus tot die gevolgtrekking
gekom word dat die Herbstmeetinstrument die Gesellmeetinstrument
sou kon vervang, mits addisionele aandag aan die evaluering van
taalkomponente gegee word

How Theory-Building Research on Instruction can Support Instructional Improvement: Toward a Modeling Perspective in Secondary Geometry
No full textHow can basic research on mathematics instruction contribute to instructional
improvement? In our research on the practical rationality of geometry teaching we describe
existing instruction and examine how existing instruction responds to perturbations. In this
talk, I consider the proposal that geometry instruction could be improved by infusing it with
activities where students use representations of figures to model their experiences with
shape and space and I show how our basic research on high school geometry instruction
informs the implementing and monitoring of such modeling perspective. I argue that for
mathematics education research on instruction to contribute to improvements that teachers
can use in their daily work our theories of teaching need to be mathematics-specific.The ideas expressed in this paper have been developed with the support of the National Science Foundation through grants REC-0133619, ESI-0353285, and DRL- 0918425 (P. Herbst, PI), and DRL- 1316241 (D.Chazan, PI).

Palladium‐Catalyzed Direct C2‐Arylation of an N‐Heterocyclic Carbene: An Atom‐Economic Route to Mesoionic Carbene Ligands
No full textGhadwal R, Reichmann SO, Herbst-Irmer R. Palladium-Catalyzed Direct C2-Arylation of an N-Heterocyclic Carbene: An Atom-Economic Route to Mesoionic Carbene Ligands. Chemistry - A European Journal. 2015;21(11):4247-4251.Blocking the C2 position of an imidazole‐derived classical N‐heterocyclic carbene (NHC) with an aryl group is an essential strategy to establish a route to mesoionic carbenes (MICs), which coordinate to the metal via the C4 (or C5) carbon atom. An efficient catalytic route to MIC precursors by direct arylation of an NHC is reported. Treatment of 1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene (IPr) with an aryl iodide (RC6H4I) in the presence of 0.5 mol % of [Pd2(dba)3] (dba=dibenzylideneacetone) precatalyst affords the C2‐arylated imidazolium salts {IPr(C6H4R)}I (R=H, 4‐Me, 2‐Me, 4‐OMe, 4‐COOMe) in excellent (up to 92 %) yields. Treatment of {IPr(C6H5)}I with CuI and KN(SiMe3)2 exclusively affords the MIC–copper complex [(IPrPh)CuI]
Educational content in the performing arts : tradition and Christianity in Kenya
No full textIncludes bibliographical references (p.235-263).The performing arts (a combination of music, dance and dramatisation) in the church in Kenya have not received much scholarly attention. These performing arts as adopted by Christian dance groups in Kenya have not been fully accepted into Christian circles because of the indigenous and popular music influences that govern them. This study therefore sets out to determine the educational role that the performing arts in the church in Nairobi play as demonstrated by a Nairobi Christian dance group, the Maximum Miracle Melodies
Digital Titanium-Herbst : effects on TMJ in a case of Juvenile Idiopathic Arthritis
No full textL’utilizzo della tecnologia CAD-CAM (Computer-Aided Design, Computer-Aided Manufacturing) si sta diffondendo in maniera esponenziale in campo odontoiatrico, dopo la sua introduzione nel campo protesico negli anni ’80. Essa trova applicazione anche in ambito ortognatodontico, infatti è possibile produrre con questa tecnologia espansori palatali, placche di Michigan, mascherine guida per ortodonzia prechirurgica.
Con questo lavoro si intende mostrare l’applicazione di una apparecchiatura Herbst prodotta con CAD-CAM in lega di titanio (DTi Herbst) in un caso di Artrite Idiopatica Giovanile (AIG).
Il paziente AIG, di 14 anni, viene sottoposto ad indagine Cone Beam TC (CBCT) e le sezioni ottenute vengono studiate nei 3 piani dello spazio. L’ATM sx presenta una marcata erosione di forma rotondeggiante nella porzione centrale della testa del condilo. E’ presente una leggera latero-deviazione durante il movimento di apertura in paziente con malocclusione di II classe e deep bite. Si decide di applicare un’apparecchiatura Herbst per portare in avanti la mandibola.
Si rilevano le impronte di precisione delle arcate dentarie e si sviluppano i modelli in gesso. I modelli vengono sottoposti a scansione con scanner a luce strutturata e si ottengono così i modelli digitali. Tramite software CAD viene progettata la struttura dell’apparecchio, che viene poi prodotto con l’utilizzo di una fresatrice a controllo numerico. L’Herbst realizzato è provato e cementato nel cavo orale con un cemento a base resinosa. Dopo la rimozione dell’apparecchiatura, ad 1 anno di distanza, si esegue una nuova scansione CBCT per verificare i risultati ottenuti.
La cerniera di Herbst è un apparecchio funzionale fisso ideato dal Dr. Emil Herbst nel 1906. Gli effetti scheletrici derivanti dall’applicazione di tale apparecchiatura si manifestano soprattutto durante il picco di crescita: in particolare a livello della mandibola si può ottenere una crescita oltre i 3mm per la dislocazione del condilo nella fossa glenoide e stimolazione di nuova apposizione ossea soprattutto nella porzione superiore e posteriore del condilo.
L’analisi della nuova TC mostra che a livello del condilo affetto c’è stato rimodellamento e neoapposizione ossea che ha colmato il divario tra condilo dx e sx causato dell’erosione presente in precedenza.
Il CAD/CAM applicato ai materiali di derivazione aerospaziale come il titanio di grado 5 rendono la progettazione e la realizzazione del DTi Herbst più semplice rispetto all’Herbst tradizionale. L’applicazione nei pazienti affetti da AIG ha fino ad ora dato risultati incoraggianti ma necessita di uno studio con un numero maggiore di pazienti.The use of CAD-CAM (Computer-Aided Design, Computer-Aided Manufacturing) is growing exponentially in dentistry, since its introduction in the field of prosthetics in the 80s. It also finds application in the orthodontic field, it can be produced with this technology palatal expanders, Michigan plates, guide masks for presurgical orthodontics.
This work intends to demonstrate the application of a Herbst appliance produced with CAD-CAM titanium alloy (DTi Herbst) in a case of Juvenile Idiopathic Arthritis (JIA).
The JIA patient, aged 14, is investigated by Cone Beam CT (CBCT) and sections obtained are studied in the 3 planes of space. The left TMJ has a marked erosion of a round shape in the central portion of the head of the condyle. And there is slight lateral deviation during opening movement with Class II malocclusion and deep bite. Herbst equipment has applied to bring the jaw forward.
We take polyvinyl siloxane dental impressions and develop models in plaster. The models are scanned with scanners and structured light so you get the digital models. Using CAD software is designed the structure of the apparatus, which is then produced with the use of a numerically controlled milling machine. The Herbst is made and cemented tried in the mouth with a cement-based resin. After removal of the equipment, 1 year later, you run a new CBCT scan to verify the results obtained.
The Herbst hinge is a fixed functional appliance developed by Dr. Emil Herbst in 1906. The skeletal effects arising from the application of this apparatus is mostly during the peak of growth: in particular at the level of the jaw one can obtain a growth beyond the 3mm for the dislocation of the condyle in the glenoid fossa and stimulation of new bone apposition especially in the portion top and back of the condyle.
The analysis shows that the new CT at the level of the condyle there was bone remodeling and neoformation that has bridged the gap between right and left condyle erosion caused this previously.
The CAD / CAM applied to the materials from the aerospace industry such as titanium grade 5 make the design and implementation of the DTi Herbst simpler than traditional Herbst. The application in patients with JIA has so far shown promising results but requires a study with a larger number of patients
