Thesis (MScEng)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: Orthodontics is the eld of dentistry concerned with the treatment of maloc-
clusion and anomalies of the dento-facial complex. This thesis is concerned
with studying the underlying biomechanical principles of orthodontic tooth
movement. It aims to develop a novel treatment approach and an orthodontic
appliance to facilitate said approach by employing advanced technologies. A
thorough review of the literature is used to form a comprehensive knowledge
base pertaining to the factors a ecting orthodontic tooth movement. It is
hypothesised that an electromechanical orthodontic appliance could improve
treatment by characterising orthodontic cases based on the relationship be-
tween the applied mechanical stimulus and the resulting changes to the af-
fected structures, which can then be sensed by the appliance. A prototype is
built using electronically controllable linear actuators and a custom built force
transducer system for measuring orthodontic forces. Electronic circuits are de-
veloped to connect the appliance to a USB port and allow it to be controlled
from a graphical user interface (GUI). This further facilitates real-time viewing
of important orthodontic parameters. Experiments are carried out to evaluate
the appliance functionality with regard to the proposed hypothesis. To con-
clude, the relevance of the results to the orthodontic eld is highlighted and
recommendations for further development of an electromechanical orthodontic
appliance are provided. / AFRIKAANSE OPSOMMING: Ortodonsie is die vakgebied in tandheelkunde gemoeid met die behandeling
van wanpassing en abnormaliteit van die tand- en gesig-area. Hierdie tesis
bestudeer die onderliggende biomeganiese beginsels van ortodontiese tandbeweging
om sodoende 'n nuwe benadering sowel as 'n ortodontiese apparaat te
ontwikkel om die genoemde benadering te fasiliteer deur gebruik te maak van
gevorderde tegnologie. 'n Deeglike oorsig van die literatuur word gebruik om 'n
omvattende kennisbasis op te bou rondom die faktore wat ortodontiese tandbeweging
a ekteer. Die hipotese word gestel dat 'n elektromeganiese ortodontiese
apparaat behandeling kan verbeter deur ortodontiese gevalle te identi seer/-
karakteriseer gebaseer op die verhouding tussen die toegepaste meganiese stimulus
en die gevolglike veranderinge aan die gea ekteerde strukture wat deur
die apparaat aangevoel word. Elektronies-beheerbare lineêre aandrywers en 'n
pasgemaakte krag-oordraerstelsel vir die meet van ortodontiese kragte word
gebruik om 'n prototipe te vervaardig. Elektroniese stroombane word ontwikkel
om die apparaat te koppel aan 'n USB poort sodat dit beheer kan word
d.m.v. 'n gra ese gebruikerskoppelvlak. Eksperimente poog om die apparaat
funksioneel te evalueer volgens die voorgestelde hipotese. Ter afsluiting: die
toepaslikheid van die verwerfde resultate in die ortodontiese vakgebied word
beklemtoon en aanbevelings word gemaak vir toekomstige/verdere ontwikkelings
m.b.t. 'n elektromeganiese ortodontiese apparaat.
