Effects of Piezoelectric Surgery on Bone Regeneration Following Distraction Osteogenesis of Mandible

Abstract

The aim of this study is to compare the bone healing in the distraction gap following the osteotomy performed with piezoelectric and conventional devices for the distraction osteogenesis in the rabbit mandibles. Twelve rabbits were randomly divided into 2 groups; 6 for piezoelectric device and 6 for rotary instruments. After 3 days of latency period, distraction was started at a rate of 1 mm per day for 10 days. All the animals were sacrificed after 4 weeks of consolidation phase for histological and histomorphological evaluation. Histological evaluation revealed thick trabecular bone formation in all of the specimens. Inflammation scores were chronic minimal. The mean percentages of the bone area in distraction gap are 62% in group P and 57% in group R. However, the difference between 2 groups was not statistically significant (P > 0.05). Our results revealed a slight increase in bone formation in the distraction gap in piezo-osteotomy groups histologically though not statistically supported. However, there is still a need for more histological studies with larger sample sizes evaluating the bone structure following piezo-osteotomies.

Mandibular distraction of free iliac crest bone graft as treatment in a patient with a history of gunshot wound. Case Report

“…Regarding this process, it has been documented that there is not only bone formation, but also tissue formation under tension stress, including mucosa, skin, muscles, tendons, cartilage, blood vessels and peripheral nerves, which explains why it is currently called distraction histiogenesis. (5)(6)(7)(8) The combination of non-vascularized iliac crest bone and distraction osteogenesis of the graft in a second surgical intervention has been described for alveolar ridge augmentation and subsequent implant placement and rehabilitation of masticatory function. (9) However, horizontal distraction of a free iliac crest bone graft for treating dentofacial anomalies and gunshot injuries has not been described to date.…”

Piezocirurgia no levantamento do seio maxilar

“…É importante o cirurgião executar uma criteriosa anamnese, posto que a piezocirurgia não pode ser usada em pacientes que possuem pacemakers cardíacos; por conta da vibração da ponta ultrassônica. Ademais, as pontas podem sofrer um desgaste cedo de seu poder de corte, diminuindo seu tempo útil e sua velocidade de secção; sugere-se usar até 10 vezes cada ponta (Tosun, et al, 2017).…”

Comparação De Técnicas Cirúrgicas Convencionais Com a Piezocirurgia: Revisão De Literatura / Comparison of Conventional Surgical Techniques With Piezosurgery: Literature Review

“…Atualmente, os dispositivos piezoelétricos são amplamente utilizados para osteotomias, como levantamento do seio maxilar, extração de terceiros molares mandibulares impactados e enxerto ósseo, na área de cirurgia oral e maxilofacial (TOSUN et al, 2017; SRIVASTAVA et al, 2018).…”
