| balanced articulation | The simultaneous contacting of the upper and lower teeth on the right and left and in the anterior and posterior occlusal areas in centric and eccentric positions within the functional range; used primarily in reference to the mouth, but also arranged and observed on articulators, developed to prevent a tipping or rotating of the denture bases in relation to the supporting structures. Synonym: balanced articulation, balanced bite. (05 Mar 2000) |
| balanced bite | The simultaneous contacting of the upper and lower teeth on the right and left and in the anterior and posterior occlusal areas in centric and eccentric positions within the functional range; used primarily in reference to the mouth, but also arranged and observed on articulators, developed to prevent a tipping or rotating of the denture bases in relation to the supporting structures. Synonym: balanced articulation, balanced bite. (05 Mar 2000) |
| balanced chromosome | <genetics> A chromosome which is unable to pair with its homologue and participate in homologus recombination during meiosis because it contains several inversion mutations (that is, has segments which have become flip-flopped). (09 Oct 1997) |
