Abstract
Orthognathic medical procedure is the foundation in therapy of skeletal
distortions. The maxillary skeletal distortion revision with
distinctive osteotomy methods apparatuses and methods for obsession still
upgradable to present negligibly obtrusive procedures and less
horrendous osteotomy apparatuses which improve recuperating and less
intraoperative or postoperative difficulties. The appropriate arranging,
legitimate careful method, appropriate unbending obsession and quick recuperating help
to acquire stable maxillary situation without backslide particularly in the
unsteady developments (descending and cross over extension
developments).
The point of the current examination was to think about between the
results of both Piezoelectric Surgical gadget and careful saw in
maxillary orthognathic with respect to the accompanying focuses:-
1. Bone thickness of each side radiographically.
2. Cut quality with respect to minimal coagulative bone putrefaction
histopathologicaly.
3. Intraoperative dying.
4. Postoperative edema.
5. Postoperative agony.
6. Osteotomy time.
The current investigation was led on 10 patients with maxillary
disparity demonstrated for orthognathic medical procedure. Lefort I was
performed for every one of them while osteotomy was performed by
piezoelectric to one maxillary side and the opposite side was
osteotomised with careful saw. This split mouth method empowered
us to identify precisely the general contrast between the two gadgets.
We evaluated the intraoperative blood misfortune which uncovered less
intrusiveness of piezo than saw with factual critical decline in
blood misfortune in piezo side than saw. While the osteotomy time was
higher with piezo than saw with measurable huge time, saving
prevelage in saw instead of piezo. In histomorphometric investigation of
bone examples from the two sides the negligible bone corruption was
insignificant with piezo which improved recuperating in piezo side than saw
side which was improved radiographicaly 3 months postoperative by
the huge high bone thickness in piezo side than saw.
Concerning torment, it was fundamentally high in saw
side than piezo in the first day postoperative yet there was no
huge contrast in torment in the late postoperative periods. In
expansion, postoperative edema uncovered no critical distinction
among saw and piezo.
The current examination presumed that piezo is an important less obtrusive
osteotomy instrument which may replace careful saw as a norm
osteotomy instrument in orthognathic medical procedure.
Piezoelectric osteotomy gadget is more protected than careful saw
bringing about less blood misfortune in maxillary orthognathic medical procedure, too
piezo decline clearly peripheral bone rot than saw which can
be radiographicaly seen at early expansion in bone thickness than
saw. The saw is better than piezo in osteotomy time yet there is no
huge contrast in edema or torment except if in the later development
(1week-4weeks) post-employable uncovered less torment sensation with
piezo instead of saw.
Recommendation
• Piezoelectric is strongly suggested as an osteotomy device all things considered
simple to be dealt with , has various shapes and sizes of osteotomy
tips for greater openness and exactness, need less expectation to absorb information
than saw which need high insight and cautious holding to
forestall calamitous slippage harm of tissues likewise Piezo can be
securely utilized near any imperative construction instead of saw.
• The interest in piezo gadget is helpful as it isn’t costly
than careful saw with the careful engine.
• Sample size ought to be bigger in additional examinations to be precisely
distinguish the clinical information like postoperative edema and agony.
• Split mouth considers are strongly suggested as it copy the
test size with no added substance singular factors in the equivalent
patient.
• Comparative radiographic evaluation of bone thickness ought to be
tried out the exploration as a negligible obtrusive evaluation device.
