Piezoelectric osteotomy for the placement of titanium implants in rabbits: histomorphometry study

Abstract

Piezoelectric osteotomy allowed bone formation for osseointegration of titanium implants, was not associated with bone necrosis, and provided results similar to those of the conventional technique. The piezoelectric technique can be considered a viable alternative in dental implantology.

Comparison of Osseointegration of Dental Implants Placed in Rabbit Tibia Using Two Dental Laser and Implant Handpiece Systems

“…Moreover, the BIC ratio did not differ between the two groups, implying that osseointegration was properly achieved in both groups. Compared to other studies, the BV/TV ratio was lower (32.92% by Kfouri et al [ 29 ], 28.66% by Barak et al [ 30 ] and 26.28% by Al-Mahalawy et al [ 31 ]), and the BIC ratio was similarly measured (52.87% by Al-Mahalawy [ 31 ]). Although BV/TV ratio was lower than other researches due to the fact that, when setting the range for measuring the BV/TV ratio, the TV range was broadened, it is meaningful in that there was no significant difference between the two groups within the present study, which means similar bone volume was gained.…”

Cutting bone with drills, burs, lasers and piezotomes: A comprehensive systematic review and recommendations for the clinician

“…Burs/drills vs piezotomes: With moderate to strong evidence (EL: 1,3; Table 1) and consecutive substantial clinical impact piezotomes seem to provide an improved bonehealing, proved on molecular-biologic, micromorphologic and histologic level in vivo, when compared to rotary instruments. Furthermore, a superior soft-tissue-preservation is reported compared to drills and burs [70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85][86].…”

Comparison between a piezoelectric device and rotary instruments in implant site preparation: an in vivo morphological, histological analysis using pigs

“…Few in vivo studies in the literature have conducted an evaluation of the histological aspects after the use of piezoelectric instruments in comparison with the conventional rotary cutting system, when preparing sites for implants [21][22][23][24] . It is important to emphasize that a direct comparison between the results of the present study and other, earlier studies is hindered by virtue of the different materials and methodologies employed and the distinct experimental models.…”

“…Similarly, there was no significant difference between the area of contact between bone and implant, however this area was significantly smaller in the group of conventional cutting instruments at 7 and at 14 days. At the end of the study, after 28 days, the authors concluded that there was no difference between the piezoelectric and conventional instruments 24 . In another study previously carried out on beagles, Bengazi et al 22 also found that osseointegration of implants is possible if the sites are prepared using conventional drill cutters with copious irrigation or by means of piezoelectric surgery.…”

“…Specifically with regard to Implant Dentistry, piezoelectric instruments have been proposed for the removal of bone grafts [13][14][15] , the preparation of the bone window in sinus lift procedures [16][17][18] and the lateralization, immobilization and transposition of the inferior alveolar nerve [19][20] . Few in vivo studies have appeared in the literature [21][22][23][24] which have evaluated the histological aspects after using piezoelectric instruments when compared to the conventional rotary cutting system in the preparation of implant sites. Moreover, the results of these studies are contradictory as regards bone neoformation in the location of the traumatized bone tissue, resulting from injury after the use of the two types of instrument, piezoelectric and conventional.…”
