Using Flexible Resin in Maxillary Obturators
A Clinical Comparative Study of Two Types of Maxillary Obturators Made of Heat Cure Acrylic Resin or Flexible Resin
Ten patients who had had maxillectomy will be assigned to two groups employing two types of 'temporary obturators. The obturators in the first group will be made from heat cure acrylic resin, whereas those in the second group from flexible resin.
A comparison will be made between the two materials in terms of oral-nasal seal using the drinking water test as well as the mirror test.

Interventie / Behandeling |
|---|---|
|
Geen tussenkomst: Traditional Obturators
Patients will use traditional obturators which are going to be made from ordinary heat-activated acrylic resin.
|
|
|
Experimenteel: Flexible Obturators
Patients will use the new obturators made from flexible resin.
|
This material 'Flexible resin' is going to be used in the construction of the 'flexible obturators'.

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Amount of leaking water drops from the nose
Tijdsspanne: 30 minutes following appliance insertion in the mouth
|
Each patient is asked to drink an amount of water and keep a specific amount of water in the mouth for two to three minutes.
He/she is asked to rotate his/her head 20-30 degrees downward and forward.
During this period the amount of leaking water drops from the nose is collected and weighted.

30 minutes following appliance insertion in the mouth
|
|
Amount of air flow through the nose during speech
Tijdsspanne: 30 minutes following appliance insertion in the mouth
|
Each patient is asked to utter the following letters: K, T, D. A cold small mirror is placed in front of the nose during the utterance of these consonants.
If a fogginess is observed on the mirror, this means that there is an oral-nasal leakage of air.
