STATEMENT OF PROBLEM: The treatment of @entity5386 @entity1 by using a complete implant-supported fixed prosthetic with distal extension has been widely studied; success is mainly dependent upon the placement of the distal implants. The location of the @entity129 determines implant placement, but the length, prevalence, and symmetry between the left and right side of the anterior loop of the @entity133 are unknown. PURPOSE: The purpose of this clinical study was to measure the anterior loop of the @entity129 , which determines the placement of distal implants, in a group of 55 Mexican @entity1 . The study expected to ascertain the average length, prevalence, and symmetry between left and right side and any sex differences. To differentiate the @entity129 path, a new technique was applied using Hounsfield unit (HU) thresholds. The null hypothesis was that no significant differences would be found between the left and right sides or between @entity1 and @entity1 for the anterior loop of the @entity129 . MATERIAL AND METHODS: Fifty-five computed tomography (CT) scans were made (Somatom Sensation 16; Siemens Healthcare) and were visualized with InVesalius software. Anterior loop measurements were made on 3-dimensional surfaces. To determine statistical differences between the left and right side and between the sexes, the t test was used. The interclass correlation coefficient test was also applied to verify the reliability of the measurements. RESULTS: Ninety percent of @entity1 showed the anterior loop of the @entity129 . The length of the anterior loop ranged between 0 and 6.68 mm, with a mean of 2.19 mm. No significant differences were found between the left and right sides or between @entity1 and @entity1 . CONCLUSIONS: The mean length for the anterior loop in the sample was 2.19 mm. As the anterior loop length shows a high degree of variability, these findings suggest that a CT scan for each @entity1 is recommended in order to visualize a safety zone before placing implants close to the mental foramen.
