abstract = {In an effort to better understand the interrelationship of the growth and development pattern of the mandible and condyle, a sequential growth pattern of human mandibles in 38 embryos and 111 fetuses were examined by serial histological sections and soft X-ray views. The basic growth pattern of the mandibular body and condyle appeared in week 7 of fertilization. Histologically, the embryonal mandible originated from primary intramembranous ossification in the fibrous mesenchymal tissue around the Meckel cartilage. From this initial ossification, the ramifying trabecular bones developed forward, backward and upward, to form the symphysis, mandibular body, and coronoid process, respectively. We named this initial ossification site of embryonal mandible as the mandibular primary growth center (MdPGC). During week 8 of fertilization, the trabecular bone of the mandibular body grew rapidly to form muscular attachments to the masseter, temporalis, and pterygoid muscles. The mandible was then rapidly separated from the Meckel cartilage and formed a condyle blastema at the posterior end of linear mandibular trabeculae. The condyle blastema, attached to the upper part of pterygoid muscle, grew backward and upward and concurrent endochondral ossification resulted in the formation of the condyle. From week 14 of fertilization, the growth of conical structure of condyle became apparent on histological and radiological examinations. The mandibular body showed a conspicuous radiating trabecular growth pattern centered at the MdPGC, located around the apical area of deciduous first molar. The condyle growth showed characteristic conical structure and abundant hematopoietic tissue in the marrow. The growth of the proximal end of condyle was also approximated to the MdPGC on radiograms. Taken together, we hypothesized that the MdPGC has an important morphogenetic affect for the development of the human mandible, providing a growth center for the trabecular bone of mandibular body and also indicating the initial growth of endochondral ossification of the condyle.},

abstract = {Objectives: To compare fixed appliances and clear aligner therapy in correcting anterior open biteand in controlling the vertical dimension in adult patients with hyperdivergent skeletal patterns.
Materials and Methods: In this retrospective study, two treatment groups of adult (_18 years old)hyperdivergent patients (mandibular plane angles of _388) with anterior open bites were included:17 fixed appliance patients and 36 clear aligner patients. Thirteen cephalometric measurementsrepresenting the vertical dimension were reported for each group. A two-sample t-test was used toassess differences in changes in mandibular plane angle and overbite between the two treatmentgroups.
Results: There were no statistical differences found in the magnitude of overbite correction and thechanges in any of the cephalometric measurements for vertical control. The clear aligner groupshowed a slightly greater amount of lower incisor extrusion (P . .009). The main mechanism ofopen bite correction was similar between the two treatment groups and was accomplished throughretroclination of the upper and lower incisors while maintaining the vertical position of the upper andlower molars.
Conclusions: Cephalometric comparison of anterior open bite correction and changes in themandibular plane angle associated with use of clear aligners and fixed appliances did notdemonstrate statistically significant differences in adult hyperdivergent patients. (Angle Orthod.0000;00:000–000.)},

abstract = {Recently, various types of the Micro-implant Assisted RPE (MARPE) were introduced to obtain greater skeletal expansion and to minimize dental effects. In the present study, we evaluated skeletal and dental effects immediately after the completion of expansion using three different types of expanders— a traditional tooth-anchored maxillary expander (TAME) and two different types of MARPE, bone-anchored maxillary expander (BAME) and tooth-bone-anchored expander (MSE) using CBCT in adolescents. Overall, the MSE group showed much greater skeletal changes than the TAME and BAME groups, especially, at the nasal floor, maxillary base, and palatal suture. About 72–78% of suture opening was at PNS, which indicates slightly more opening anteriorly than posteriorly; however, it was relatively parallel in nature than anticipated. In all three groups, the greatest transverse changes with expansion occurred at the molar crowns and the 2nd greatest changes at the palatal suture opening at ANS. It is suggested that MSE can be a great alternative method in correcting maxillary skeletal transverse deficiency.},

A two-sample t-test was used toassess differences in changes in mandibular plane angle and overbite between the two treatmentgroups.
Results: There were no statistical differences found in the magnitude of overbite correction and thechanges in any of the cephalometric measurements for vertical control. The clear aligner groupshowed a slightly greater amount of lower incisor extrusion (P . .009). The main mechanism ofopen bite correction was similar between the two treatment groups and was accomplished throughretroclination of the upper and lower incisors while maintaining the vertical position of the upper andlower molars.
Conclusions: Cephalometric comparison of anterior open bite correction and changes in themandibular plane angle associated with use of clear aligners and fixed appliances did notdemonstrate statistically significant differences in adult hyperdivergent patients. (Angle Orthod.0000;00:000–000.)},

abstract = {Recently, various types of the Micro-implant Assisted RPE (MARPE) were introduced to obtain greater skeletal expansion and to minimize dental effects. In the present study, we evaluated skeletal and dental effects immediately after the completion of expansion using three different types of expanders— a traditional tooth-anchored maxillary expander (TAME) and two different types of MARPE, bone-anchored maxillary expander (BAME) and tooth-bone-anchored expander (MSE) using CBCT in adolescents. Overall, the MSE group showed much greater skeletal changes than the TAME and BAME groups, especially, at the nasal floor, maxillary base, and palatal suture. About 72–78% of suture opening was at PNS, which indicates slightly more opening anteriorly than posteriorly; however, it was relatively parallel in nature than anticipated. In all three groups, the greatest transverse changes with expansion occurred at the molar crowns and the 2nd greatest changes at the palatal suture opening at ANS. It is suggested that MSE can be a great alternative method in correcting maxillary skeletal transverse deficiency.},

(Type: Journal Article | Abstract | Links | BibTeX | Tags: adult, anterior openbite, clear aligners, clinical orthodontist, Cone-beam computed tomography, craniofacial, Discrepency Index, hyperdivergent, Mandibular fixed retainer, Posttreatment, pressure tension)@article{Lee2001, In an effort to better understand the interrelationship of the growth and development pattern of the mandible and condyle, a sequential growth pattern of human mandibles in 38 embryos and 111 fetuses were examined by serial histological sections and soft X-ray views. The basic growth pattern of the mandibular body and condyle appeared in week 7 of fertilization. Histologically, the embryonal mandible originated from primary intramembranous ossification in the fibrous mesenchymal tissue around the Meckel cartilage. From this initial ossification, the ramifying trabecular bones developed forward, backward and upward, to form the symphysis, mandibular body, and coronoid process, respectively. We named this initial ossification site of embryonal mandible as the mandibular primary growth center (MdPGC). During week 8 of fertilization, the trabecular bone of the mandibular body grew rapidly to form muscular attachments to the masseter, temporalis, and pterygoid muscles. The mandible was then rapidly separated from the Meckel cartilage and formed a condyle blastema at the posterior end of linear mandibular trabeculae. The condyle blastema, attached to the upper part of pterygoid muscle, grew backward and upward and concurrent endochondral ossification resulted in the formation of the condyle. From week 14 of fertilization, the growth of conical structure of condyle became apparent on histological and radiological examinations. The mandibular body showed a conspicuous radiating trabecular growth pattern centered at the MdPGC, located around the apical area of deciduous first molar. The condyle growth showed characteristic conical structure and abundant hematopoietic tissue in the marrow. The growth of the proximal end of condyle was also approximated to the MdPGC on radiograms. Taken together, we hypothesized that the MdPGC has an important morphogenetic affect for the development of the human mandible, providing a growth center for the trabecular bone of mandibular body and also indicating the initial growth of endochondral ossification of the condyle. |
