what to do when the bite of your dentures is off

A wax attempt-in of the denture teeth is an important step in the fabricating process.  This allows the doctor to confirm fit and function and allows the patient to preview their new smile earlier information technology is finished.  Using the information provided at the bite rim phase, your denture technician will set up the advisable size, shape and the requested shade of teeth in wax on the base plates. If the patient has large undercuts present, the baseplate may feel loose which may require y'all to use denture adhesive to assure the right position of the baseplate for the try in. The fit volition be correct after processing.

With the ready up's in place, have your patient smile with their new teeth.

Ostend the patient'southward VDO. If y'all are duplicating a patient's previous VDO, simply measure the patients VDO with their old dentures and with the wax try in. If you are opening the VDO of a patient whose bitemayhave collapsed due to wear, cheque how the new prepare upwardly looks and functions to make up one's mind ifthis VDO is comfortable for the patient.

This patient's VDO is likewise closed

• Check the position of the centrals. Confirm that the upper and lower midlines lucifer. Confirm that the midline falls in the correct place on the patient's face up.  If non, marking the right midline past scoring the wax or writing directly on the denture teeth with a sharpie marker.

• Check the plane of occlusion. If the teeth look slanted to i side you can marking the correct plane of apoplexy by cartoon a straight line perpendicular to the floor directly on the anterior teeth with a sharpie marker.

This patient'due south midline and occlusal plane are wrong.

• Check the height of the upper anterior teeth. You should come across no more than 2 mm of gingival tissue above the tooth in a full smile.  If the prepare teeth wait as well "gluey" or the upper anterior teeth look too depression or the lower anterior teeth expect to high, your VDO may be too large.

This patient's VDO is too open up.

If the occlusion is correct but y'all are seeing as well much mucilage, score or draw a horizontal line in the wax at the position of the patients lip when smiling. This volition show your technician how much to adjust the VDO when resetting the teeth.

Accept the patient bite downward.

• All the teeth should occlude evenly and the anteriors should display 1 -2 mm of overbite and i-2mm of over jet.

Note:
-   If your patient is a class 2 you volition see 3-5 millimeters of overjet and three-5 mm of overbite.
-   Course 3 will have an underbite of still many mm the jaw position requires.

• If your patient is unable to bite down completely, or if the anterior teeth are open, there may be an interference from the posterior teeth or wax. Pop any teeth that are preventing total occlusion out of the upper or lower bite rim. Cut abroad whatever additional wax that is interfering. In some cases, information technology may be necessary to remove some of the base of operations plate roofing the tuberosities or the retro molar pads.  These volition can be added back earlier processing. Once patient can fully occlude and the anteriors are closed, confirm the VDO and accept a bank check bite directly over the base plates and whatever remaining teeth existence sure your patient is fully and accurately occluded. PVS bite fabric is best for this.  Render the teeth to the lab to be reset.

This patient'southward anterior teeth are too open due to posterior interference

• For cast partials, if a clasp or rest is striking the opposing and causing the bite to be open up unnaturally, take an additional bite with the offending partial removed and make a note that the clasp/rest is interfering so the lab can modify it before processing the case.

• Check the side contour. Be sure the lips await natural, non too protruded or ditched in. The upper inductive teeth should exist flared just slightly to the incisal and the lip should be supported when speaking and smile. You lot can correct your patient'southward natural overjet past a few millimeters merely call up, placing anterior teeth also far back on the ridge can interfere with normal role and due to stress, over time, can crusade the forepart teeth to be knocked out or for the denture to fracture down the eye. Teeth that are not placed correctly on the ridge can too cause your patient to whistle or lisp when speaking.

  When the patient can bite, speak and smile comfortably, your dentures are prepare to exist processed.  Make a annotation of any changes you lot wish to brand in size, shape or shade on the Rx. Note which acrylic shade would look nearly natural for the patient'southward gums.  If your technician has requested a wash impression due to contempo extractions or a short or distorted model, utilise light trunk PVS impression cloth and be sure the patient is fully and accurately occluded when the impression material is setting. If yous are making several changes, it is recommended to endeavor the teeth in wax once again before processing and finishing to exist certain everything is exactly right.

  With the correct measurements, materials and communication, your denture teeth try in volition exist a successfully completed denture case.
