While assessing maxillary arch depth, the study showed (Table 1) a decrease in arch depth which can be because of more of transverse expansion, which created space and helped in unravel- ing of crowding in upper anteriors and less proclination.
Hence, this study shows that an optimal anesthesia can be achieved in the maxillary arch by using 2% lidocaine hydrochloride with 1: 200,000 epinephrine for only buccal infiltration and a supplemental palatal infiltration injection may not be needed.
This is in agreement with a standpoint, proposed by Peavy & Kendrick that "the closer the rugae are to the teeth, the more prone they are to stretch in the direction that their associated teeth move" This is also consistent with the point of view of van der Linden & Almeida that change in shape of maxillary arch (for example expanding arch) and extraction of maxillary anterior teeth can lead to displacement of distal endpoint of the palatal rugae.
Similarly, six implants were planned to be placed in the maxillary arch. Two implants of 4.75 mm width and 11.5 mm length were placed in the 16 and 26 regions immediately after extraction and osteotomy.
Expansion of the maxillary arch was required; therefore, rapid maxillary expansion was performed following the intrusion.
We concluded that early RME produces transverse increases in the maxillary arch with nearly 80% stability after three years of follow up and without significantly altering dentoskeletal measures in the vertical or sagittal directions and neither inclined teeth.
With the help of custom made stainless steel metal plate which is small enough to enter into Childs mouth, Algitex material (Nonirritant to mucosa, skin) was used to get negative impression of maxillary arch of cleft child.
Narrower maxilla or deeper palatal height has been recorded in obstructed patients in the present study and several other studies.2,9,23 Some previous reports have found an increase (improvement) in maxillary arch width and spontaneous normalization of some posterior crossbites after adenotonsillectomy.23,24
Another feature of the FR is its ability to facilitate maxillary arch width expansion.
