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. |
