This trial is active, not recruiting.

Condition edentulous
Treatments zero degree teeth, anatomic teeth
Sponsor Haixin Qian
Start date June 2014
End date April 2015
Trial size 20 participants
Trial identifier NCT02359955, 201395

Summary

This study aims to evaluate masticatory efficiency of the zero-degree teeth complete denture in treatment of edentulous patients of severely resorbed ridge.Patients will be crossed over to be treated with zero-degree teeth complete denture and anatomic teeth complete denture. For each patient, the masticatory efficiency and electromyography with different denture will be recorded and analysis.

(Experimental)
edentulous patients who were first treated with zero-degree teeth complete denture, then with anatomic teeth complete denture
zero degree teeth
zero degree teeth complete denture was first prescribed to patients in group 1 while patients in group 2 were treated with anatomic teeth complete denture
anatomic teeth
when anatomic teeth complete denture was prescribed to patients in group 1, patients in group 2 were treated with zero degree teeth complete denture
(Experimental)
edentulous patients who were first treated with anatomic teeth complete denture, the with zero degree teeth complete denture

anatomic teeth
when anatomic teeth complete denture was prescribed to patients in group 1, patients in group 2 were treated with zero degree teeth complete denture
