Temporo-mandibular joint condylectomy and its effect over occlusion in XXXX : cadaveric study.

@entity1 @entity235 @entity89 @entity432 @entity468
OBJECTIVE: To determine the effect of unilateral condylectomy on @entity432 in @entity468 . METHODS: Twelve feline cadaver heads were randomly submitted to either a right or left unilateral condylectomy of the temporo-mandibular joint. The distance between the mandibular and maxillary @entity235 tooth was measured before (B0) and after the unilateral condylectomy (P0). A right or left latero--lateral standardised force (4 N) was applied to the mandibular mentus area before and after the surgical procedure. These measurements were analysed with a linear model for repeated measures. RESULTS: The comparative analysis between pre- and postsurgical values indicated no significant variation in teeth displacement following condylectomy between B0 and P0 measurements. Statistically significant differences were detected after either left or right condylectomy with respect to all measurements after application of the standardised forces. Occlusion changes are significant when comparing bites before and after surgery. CLINICAL SIGNIFICANCE: Unilateral condylectomy causes a significant increase in latero-lateral amplitude of @entity89 which might clinically affect feline @entity432 . Clinical studies are required to determine the effect of unilateral condylectomies on mastication and @entity432 in feline @entity1 .
