Análisis morfogeométrico de la estructura cortical en incisivos centrales mandibulares mediante TCCB, innova 2019.

Abstract

Introduction: The jaw in the anterior sector is an area that presents problems when making diagnoses and treatment plans. This is because the dimensions of the vestibular table of the mandibular incisors are very small compared to the lingual table. The application of CBCT can provide crucial information in the study of the morphology of the mandibular bone cortex. Objective: To determine the morphogeometric analysis of the cortical structure of the central mandibular incisors using CBT. Materials and methods: study of an imageneological, descriptive, non-experimental, cross-sectional observational study. The sample is made up of 60 tomographs obtained from a database of 168 patients Results: The dimension of the bony corticals of piece 31 was analyzed, the results of which were that the oral buccal cortex approximately 2.03 mm and the lingual cortex 2.43 mm also in piece 41 the oral cortex measured 1.97 mm and the lingual cortex 2.51mm Bone density was established in the cortex of the central mandibular incisors using the Misch Index, the results of which were: D1: 0%, D2: 10%, D3: 78%, D4: 17%. As a result, 57% of bone dehiscences and 43% of absences were projected in piece 31, in piece 41 60% of bone dehiscences and 40% of absences.Conclusion: It was determined that the lingual cortex is larger than the vestibular cortex, finding a difference of 0.99 mm between the cortices. We could also identify that there was a prevalence in bone density of 73% of type D3 bone, also determining the height of the vestibular table with an approximate result of 7, 55 mm in piece 31 and in piece 41 giving an approximate average 8.21 mm, we consider the presence of bone vestibular cortical dehiscence, resulting in more than 50% of dehiscence found in the vestibular cortex of the mandibular central incisors.
