Healing of cancellous bone osteotomy in rabbits—Part I: Regulation of bone volume and the regional acceleratory phenomenon in normal bone

Journal of Orthopaedic Research, 1993
AbstractWe performed a simple, undisplaced, incomplete osteotomy of the distal medial condyle of mature New Zealand White rabbits and permitted healing without fixation for 4 weeks. During the recovery period, the rabbits received the bone label calcein in their drinking water. From ground stained and unstained sections, we determined histomorphometric

Hypoxia‐induced factor 1α promotes osteotomy‐induced regional acceleratory phenomenon via DC‐STAMP mediated membrane fusion

Oral Diseases, 2022
Abstract Objectives The mechanisms of regional acceleratory phenomenon (RAP) induced by orthognathic osteotomy are unclear. It was not known if locally hypoxic microenvironment changes were involved in this phenomenon. Methods

Regional Acceleratory Phenomenon

Frontiers of oral biology, 2015
The regional acceleratory phenomenon (RAP) is a tissue reaction to a noxious stimulus that increases the healing capacities of the affected tissues. It is typical not only of hard tissues such as bone and cartilage, but also of soft tissues. The RAP is characterized by acceleration of the normal cellular activities, as an 'SOS' phenomenon of the body ...

Influence of Inflammation-Mediated Osteopenia on the Regional Acceleratory Phenomenon and the Systemic Acceleratory Phenomenon During Healing of a Bone Defect in the Rat

Calcified Tissue International, 1998
We have previously shown that restoration of a local bone defect in the rat not only leads to a regional acceleratory phenomenon (RAP), but also to a systemic acceleration of osteogenesis (SAP) at distant sites of the skeleton. In this study, we investigated whether specific inhibition of osteoblasts would affect the local RAP and the systemic ...

Effect of prostaglandin E1 on the periosteal regional acceleratory phenomenon in fractured ribs: Histomorphometric study in Beagles

American Journal of Veterinary Research, 1987
SUMMARY Transverse fractures were made surgically in the midshaft of the left 9th and 10th ribs in adult Beagles. A buffer vehicle (n = 4) or 0.2 mg of prostaglandin (pg) e1/day (n = 6) was injected into the fracture sites twice a day for 10 days, and dogs were euthanatized on day 30.

The relationship between the expression of stromal cell derived factor-1 (sdf-1) and regional acceleratory phenomenon (rap) in orthodontic tooth movement after tooth extraction in rats model

The stromal cell-derived factor 1 (SDF-1)/chemokine receptor type 4 (CXCR4) axis plays a key role in alveolar bone metabolism during orthodontic tooth movement (OTM). Herein, the effects of the SDF-1/CXCR4 axis on the regional acceleratory phenomenon (RAP) in OTM velocity and on changes in the surrounding periodontium after adjacent tooth extraction in

PERIODONTALLY ACCELERATED OSTEOGENIC ORTHODONTICS (PAOO): PRINCIPLES, BIOLOGICAL BASIS AND CLINICAL APPLICATIONS

Archiv Euromedica
Background: Periodontally Accelerated Osteogenic Orthodontics (PAOO) is an advanced technique that combines conventional orthodontic treatment with selective corticotomy and alveolar bone augmentation to significantly shorten treatment time.

Surgical Corticotomy-Assisted Orthodontics in the Management of Bimaxillary Prognathism.

The Journal of craniofacial surgery (Print)
OBJECTIVES The aim of this case report is to present the effectiveness of corticotomy-assisted orthodontic camouflage treatment in an adult patient who refused orthognathic surgery, focusing on the management of mandibular protrusion and the clinical ...
