Dentistry Quiz

What are the errors that can result from clinical errors in registering maxillo-mandibular relationship?

• Errors in mounting models on the articulator

• Errors in occlusion

• Errors in intraoral methods

• Errors arising during processing of the dentures

Which method can be used to locate interferences in functional movements but may give false readings due to the resiliency of the underlying soft tissues?

• Central bearing devices

• Articulating paper

• Occlusal wax

• Abrasive paste

What is the disadvantage of using abrasive paste for detecting occlusal errors?

• It is not accurate in detecting interferences

• It causes shifting of the bases resulting in premature contacts

• It is not selective

• Cusps that maintain the occlusal vertical dimension may be destroyed

What is the purpose of central bearing devices in correcting occlusal disharmony?

• To add wax to the mandibular denture

• To correct errors in mounting models on the articulator

• To locate interceptive occlusal contacts with articulating paper

• To prevent shifting of the dentures

What is the importance of remounting dentures?

• To easily locate and correct occlusal errors

• To discomfort the patient

• To deform underlying tissues

• To conceal occlusal errors

When is laboratory remounting performed?

• After clinical remounting

• After processing the dentures

• After handing the dentures to the patient

• Before deflasking the dentures

What is the advantage of laboratory remounting?

• Errors in the processed denture are easily spotted on the articulator rather than in the patient's mouth

• It allows for immediate correction of occlusal errors

• It requires less time than clinical remounting

• It is more comfortable for the patient

What records are obtained from the patient for clinical remounting?

• Facebow record and centric relation record

• Facebow record and occlusal wax record

• Articulating paper record and centric relation record

• Occlusal wax record and centric interocclusal record

What is the purpose of selective grinding?

• To increase the occlusal vertical dimension

• To add wax to the mandibular denture

• To remove all occlusal contacts

• To modify the occlusal and incisal surface of the teeth by grinding at selected positions

How can high spots in occlusion be detected?

• Using central bearing devices

• Using abrasive paste

• Using occlusal wax

• Using articulating paper
