Occlusal Splint Therapy Flashcards
(24 cards)
What name upper splint used splint therapy?
Michigan splint
Example of lower splint used splint therapy?
Tanner appliance
Examples of other splints used splint therapy?
Occlusal splints
Stabilisation splints
What can be splints be made from?
Hard or soft acrylic
Hard more effective
What is an occlusal splint?
Removable device made of acrylic resin that fits between mandibular and maxillary teeth
Indications splint therapy?
TMJ dysfunction and pain Dx occlusal disharmony Severe bruxism Establish CR Protection extensive dental work
Aims splint therapy?
Allow condyle seat optimal position - stabilise and improve function TMJ
Optimal function neuromusculature system
Protect teeth adverse loading/ attrition
How effective are splints?
Most effective pain of musculature origin
Features of splint?
Uniform contact in CR
Canine guidance to separate posterior teeth in lateral excursion
Anterior guidance on protrusion
What does full coverage split do?
Create ideal occlusion
Clinical stage of splint construction?
Visit 1: upper and lower alginate imps and facebow to record jaw reg in CR
Visit 2: fit
Review: may need adjust so in CR
How fit splint?
Seat and check for retention and even coverage
Initial ICP= RCP
Check ideal occlusion
Adv of soft splint?
Better tolerate by pt
Easily constructed
Cheap
Disadv soft splint
Hard adjust
Encourage bruxism
What is occlusal adjustment?
Adjusting to remove unwanted/interfering contacts
How adjust occlusion
Carefully - don’t remove excessive tissue
Need accurate record occlusion prior
Informed consent
When may want to adjust the occlusion
Eliminating fremitus in periodontally involved tooth
Reducing cusp of over erupted tooth
Reduce load on compromised tooth
What is occlusal equilibrium?
Reorganising to give ideal occlusion by selective adjustment
What is Dahl concept?
A procedure where restorative placed in supra-occlusion with intention of dentition to adapt to altered occlusal scheme - achieve even contact ICP via -over-eruption and intrusion
Basic Dhal concept?
Placing restoration in supra-occlusal
Posterior teeth will re-establish contact
Indication to use Dhal?
Anterior tooth wear case when loss vertical height
Restoring teeth normal contour by increased VD
How plan a case when want to use Dhal?
Impressions/ facebow and occlusal records
Diagnostic wax up on cast
Pt - informed consent
What to warn pt of if using Dahl?
Functional issues for a few weeks - achieve occlusal contact 6-8 weeks
Issues of using Dahl?
Most pt adapt quickly - some may not
Small no of pt tooth movement won’t occur - may need restorative intervention of posterior teeth
