Impaired osseointegration of dental implants associated with orthognathic surgery: Possible regional acceleratory phenomenon

open access: yesClinical Implant Dentistry and Related Research, 2019
AbstractBackgroundRegional acceleratory phenomenon (RAP) is demonstrated to decrease regional bone mineral density and accelerate bone turnover. Hypothesizing that RAP can negatively affect the osseointegration of biomaterials, this study aimed to investigate the possible influence of the RAP on dental implant osseointegration.Materials and ...

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

open access: yesJournal 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

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

open access: yesCalcified 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 ...

Regional Acceleratory Phenomenon

open access: yes, 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 ...

Utilizing the Regional Acceleratory Phenomenon and Dental Implant Anchorage for Distalization and Intrusion of a Mesially Tipped Mandibular Molar: A Case Report

open access: yesClinical Advances in Periodontics, 2020
IntroductionIntroduction of a surgical insult in conjunction with orthodontic therapy has been shown to accelerate treatment in minor tooth movement and comprehensive orthodontic cases by induction of the regional acceleratory phenomenon (RAP). When applying this concept to a molar tipped into an adjacent edentulous site, a dental implant can be ...

Interdental Osteotomies Induce Regional Acceleratory Phenomenon and Accelerate Orthodontic Tooth Movement

Journal of Oral and Maxillofacial Surgery, 2014
Although it has been revealed clinically that double-jaw orthognathic surgery induces a systemic increase in the baseline bone turnover and subsequently accelerates postoperative orthodontic tooth alignment, it is not clear whether less extensive osteotomy, such as interdental osteotomy, would be intensive enough to accelerate postoperative orthodontic

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.

Pilot Study on the Histological Assessment of the Regional Acceleratory Phenomenon Reaction Following Micro-Osteoperforations

open access: yes
The aim of this study is to evaluate in humans whether the Regional Acceleratory Phenomenon (RAP) resulting from micro-osteoperforations (MOPs) performed with Propel® can be histologically demonstrated, supporting the ability of this technique to accelerate orthodontic movement.

The regional acceleratory phenomenon: a review.

open access: yesHenry Ford Hospital medical journal, 1983
The regional acceleratory phenomenon (RAP) is a complex reaction of mammalian tissues to diverse noxious stimuli. The phenomenon occurs regionally in the anatomical sense, involves both soft and hard tissues, and is characterized by an acceleration and ...
