Midpalatal suture maturation staging using cone beam computed tomography in patients aged between 9 to 21 years Article Full-text available Mar 2022 Fabio Savoldi Ki Kwan Wong Andy Wai Kan Yeung. It is worth mentioning that the skeletal/dentoalveolar expansion pattern may be attributed to individual craniofacial characteristics, such as the degree of midpalatal suture maturation. the primary aim of this study was to assess the correlation between the amount of achieved skeletal expansion with midpalatal suture density on computed tomography images, and the secondary aim was to assess the correlation between the amount of achieved skeletal expansion with the recently suggested midpalatal suture maturation indicators: … These studies also have determined considerable variability in the chronologic age for ossificationof the midpalatal suture[5,9]. Midpalatal suture was analysed with cone beam computed tomography to identify its maturation with respect to age and maxillary-complex growth in 72 patients 9- to 21-year-old. Midpalatal suture maturation stages (MPSMS) With respect to age, the MPSMS did not show any significant difference among stages. Midpalatal suture was analysed with cone beam computed tomography to identify its maturation with respect to age and maxillary-complex growth in 72 patients 9- to 21-year-old.

Fusion of the palatine (stage D) and maxillary (stage E) regions of the midpalatal suture was completed after 11 years only in girls. The midpalatal suture tended to mature with age. Kruskal-Wallis and Mann-Whitney U tests were used to analyze the difference between groups. Results Angelieri et al.,10 in 2013, proposed five stages of this method for moving blocks of teeth in the lateral maturation of the midpalatal suture. The following descriptive stages of midpalatal suture maturation are proposed ( Fig 4 , A and B ). Bone density of the midpalatal suture was measured at the maxillary and palatal regions. tween the midpalatal suture maturation and skeletal devel-opment and reported that the maturation of the midpalatal suture is closely related to skeletal development[5-8]. Sutural morphology can vary between stages, and diagnostic criteria are based on the decision tree in Band the definitions of the 5 stages. It is a simpli- fication of the sutural morphology and should not be used for diagnosis. Introduction: A reliable method to assess midpalatal suture maturation to drive clinical decision-making, towards non-surgical or surgical expansion, in adolescent and young adult patients is needed. The midpalatal suture has been described as an end-to-end type of suture 16, 17 with characteristic changes in its morphology during growth. With respect to growth, an increase of maxillary-complex length was present between stage A and B ( p = 0.001), which was limited to females. Currently, the midpalatal suture in patients aged more than 14 there is no available literature on the usefulness of years. 5). Five stages of maturation of the midpalatal suture were identified and defined: stage A, straight high-density sutural line, with no or little interdigitation; stage B, scalloped appearance of the high-density sutural line; stage C, 2 parallel, scalloped, high-density lines that were close to each other, separated in some areas by small low-density spaces; stage D, fusion completed in the . Objective: To evaluate the stages of midpalatal suture (MPS) maturation in patients older than 15 years, and to determine the correlation between the stage of MPS maturation and age and cervical.
