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 ...

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 ...

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

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 ...

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. [PDF]

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 ...

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
