ABSTRACT


Purpose: The Aim Of This Study Was To Assess The Changes In The Articular Eminences And Glenoid Fossae In Kennedy Class I Patients Versus Complete Dentate Patients By Cone Beam Computed Tomography (CBCT). The Ultimate Goal Of The Study Was To Estimate The Effect Of Loss Of Posterior Teeth On The Temporal Components Of The Temporomandibular Joints (TMJ) In Partially Dentate Patients. Patients And Methods: This Study Was Performed On One Hundred Patients Requesting CBCT Scans; Fifty Kennedy Class I Patients And Fifty Fully Dentate Controls. Articular Eminence Height, Inclination And Thickness Of The Roof Of Glenoid Fossa Were Measured In Both Groups.

Results: There Was No Statistically Significant Difference Between Kennedy Class I Patients And The Control Group Regarding Eminence Height. Kennedy Class I Group Showed Statistically Significant Difference With The Control Group Regarding Eminence Inclination. The Study Group Showed Statistically Significant Higher Mean Articular Eminence Inclination And Fossa Roof Thickness Than The Control Group.

Conclusions: Loss Of Mandibular Posterior Teeth Causes Significant Increase In Articular Eminence Inclination And Glenoid Fossa Roof Thickness, While The Articular Eminence Height Doesn?t Change Significantly.
