Etiology of Wear
|
-Environmental factors (silica, tobacco, foodsftuffs)
-Patient factors: Bruxism/GERD -Iatrogenic factor: restoration in hyper-occlusion -Materials factors: (unglazed porcelain, composites) -Lack of posterior support |
|
|
What is a good way to maintain VD when you're do full mouth reconstruction?
|
-Keep some unprepared teeth presents and in occlusion to maintain VD
-Repeatability of CO (need home base to return to |
|
|
Describe the treatment planning of changing vertical dimension?
|
-To increase VD, use average tooth dimension in Wheelers and use 2/3 the high of retromolar pad and 4 inch curve
|
|
|
What is a challenge in in changing VD?
|
-Maintainging VD that you altered
-Consider rapid TXD, composite resin provisional materials, restoring posterior teeth w/ temporary metal crowns. -Dentist should provide adequate retention and resistance form due to existing wear. -For R&R, once should consider electivce and endo. therapy, dowel or core, and resistance groove placement. |
|
|
What ist he proper technique for a resistance groove placement?
|
-Involves a #272 bur at half of its diameter, in the axis of prep, 1mm coronal to margin
|
|
|
Why is the use of custom incisal guide table important?
|
-If you plan on restoring the curvilinear lingual surfaces of the anterior teeth
-Make an custom guide table that preserves the anterior guidance and only changes the VDO |
|
|
The main concern when restoring severely worn dentition is what?
|
-Finding materials to use that will not promote more wear. Metal Occlusal surfaces (rexillium III-non precious metal, etched w/ Panavia F composite resin)
-Well polished and glazed porcelain -Always provide pt with occlusal guard after TX to protect the restorations |
|
|
Typical causes of Wear
|
-Bruxism
-Environmental -Bulimia -Anorexia Nervosa -GERD -Hiatal Hernia -High amount of HCl in swimming pool |
