Within the limitations of our study (number of animals, duration in time, and limited data on the anabolic activity), our preliminary results suggest that Piezocision-facilitated orthodontic tooth movement increases the rate of movement of the teeth undergoing orthodontic treatment through the coupled remodelling of the alveolar bone. This process is initiated by the osteoclastic activity following surgery and extended via the synergistic relationship between Piezocision and tooth movement.

Avec un nombre croissant d’adultes se présentant en consultation orthodontique, la demande d’un traitement de courte durée revient de manière récurrente de la part des patients. Afin de répondre à ces attentes, plusieurs techniques ortho-chirurgicales visant à accélérer les mouvements dentaires ont été publiées mais se sont révélées relativement invasives. Nous introduisons ici une technique ortho-chirurgicale novatrice, minimalement invasive, sans lambeau muco-periosté, combinant micro-incisions, incisions corticales piézoélectriques et tunnelisation sélective permettant des greffes osseuses et gingivales. En associant plan de traitement consciencieux et compréhension des phénomènes biologiques impliqués, le métabolisme osseux alvéolaire peut ainsi être localement manipulé par cette nouvelle technique afin d’obtenir des résultats orthodontiques stables et rapides. La piézocision permet la correction rapide de malocclusions sévères sans présenter les inconvénients des approches chirurgicales extensives et traumatiques des corticotomies alvéolaires classiques.

Introduction Peri‐implantitis has become a prominent challenge among clinicians worldwide, leading to severe bone loss and potential implant removal. Such cases require extensive regenerative surgical procedures to replace the ridge prior to implant replacement. This case report introduces a novel protocol after implant removal for the vertical and horizontal regeneration of the posterior mandible. Case Presentation A 43‐year‐old female patient was referred to Dr. Surmenian's clinic after severe peri‐implantitis was detected in her left mandible. Implants were atraumatically removed; however, major bone atrophy resulted after implant removal. The patient was scheduled for a ridge augmentation procedure utilizing a combination of titanium mesh to maintain space and an allograft rehydrated in platelet rich fibrin (PRF). Results Both vertical and horizontal bone regeneration were achieved with a bone gain of 8.2 mm in height. Thereafter, 3 × 10 mm implants were successfully placed. Conclusion This case report describes a simplified protocol used to obtain drastic vertical and horizontal bone gain of the posterior mandible, without requiring autogenous bone, expensive recombinant growth factors, and/or non‐resorbable membranes.
