Improving orthodontic treatments by minimizing side effects and broadening their range has been a top priority for clinicians and researchers. Corticotomy, an established technique, has recently gained increased attention. However, confusion and misinterpretation surrounding the term, its application, and its benefits have led to global horizontal (pioneers worldwide) and low vertical diffusion (members of the same society). This underscores the need for a dedicated book on corticotomy or Periodontally Accelerated Osteogenic Orthodontics®. The introduction to the first edition, written 10 years ago, remains relevant today. Despite yearly evidence demonstrating the procedure’s effectiveness and safety, orthodontic attention remains unchanged, shifting focus to 3D Digital Planning and Clear Aligners. The preferred terms used to describe the procedures have also evolved, with corticotomy‐facilitated orthodontics (CFO), accelerated osteogenic orthodontics (AOO), and selective alveolar decortication gaining preference. Orthodontically driven osteogenesis (ODO), or the ability to grow new bone, is now favored over regenerative. The osteogenic potential, combined with bone grafting, can expand basal bone. This leads to two positive effects: less extraction of healthy premolars in growing patients and a more robust periodontium that prevents recessions during orthodontic movement. This concept initiates tissue engineering in orthodontics, where orthodontists and dental surgeons should define themselves as dentoalveolar orthopedists and embrace this new treatment philosophy. This approach maintains the promise of a faster orthodontic treatment and expands the limits of a safer one. It also offers a sound alternative to more invasive procedures, such as orthognathic procedures and can even modify the lower third of the face. This is impressive for a localized periodontal surgery when correctly combined with orthodontic treatment.
As per the principles of innovation and change, “technology transfer” encompasses all activities that result in any user adoption of a new product or procedure. The term “new” here denotes any improvement over existing technologies or processes rather than a recent invention. Technology transfer necessitates active interaction between technology sponsors and users, which leads to actual innovation. It is crucial to differentiate between innovators or early adopters and late adopters. Innovators are individuals or groups willing to take risks by adopting new methods, products, or practices not widely used. They provide practical evidence that an innovation works, which is vital for later adopters.
Conversely, diffusion refers to the spread of an idea, method, practice, or product throughout a social system. There are various kinds of technology transfer, including horizontal transfer (the movement of information on technology between innovators within an organization or between similar organizations) and vertical transfer (the movement of information on technology from innovators to late adopters of an organization or system of organizations).
ODO has been increasingly successful worldwide, resulting in extensive horizontal diffusion. However, paradoxically, the highest percentage of orthodontists in any developed country will either ignore or be skeptical of ODO and fail to present it to their patients as a viable and valuable alternative due to a lack of vertical diffusion. There are different reasons to explain this difference in diffusion, but it is important to note that natural resistance to change is just one factor.
The innovation is not disseminated. Given that the “innovation” is truly innovative, one of the most important driving factors is the economical one. For example, most of the innovations in dentistry in the last 30 years, from implants to membranes to clear aligners or straight wire, have been “encouraged” by suppliers and manufacturers. It is the same as in the pharmaceutical business: any revolutionary drug to cure a rare syndrome would suffer a difference in diffusion compared to Viagra
®
or Biposphonates or Statins.
The innovation is disseminated to the wrong people. The information is not referred to the proper person or somehow gets lost on the way.
The innovation is not understood by the potential user.
Most of the time, this is created by a superficial knowledge of the technique or misinterpretation, lack of homogenous terminology, and underestimation of potential benefits.
3D digital planning may be the correct driver for the diffusion of ODO: It becomes more difficult to ignore when the roots extend beyond the original bony envelope.

This chapter is dedicated to Professor Spiro Chaconas, Founder and Chairman Emeritus, Section of Orthodontics, UCLA School of Dentistry. Professor Chaconas, presently enjoying a well‐deserved retirement in Sothern California, was an exceptional leader, friend, and mentor for over three generations of orthodontists at UCLA. He taught his protégés to enter private practice with confidence and engage the inevitable vicissitudes of our careers – many rather brutal – with professional élan, stoic indifference, transcendent vision, and personal humility. We did.
Thank you, Spiro.
Since 2001, this author – dual‐certified in both orthodontic and periodontic – has collaborated with a number of orthodontists and periodontists in an effort to engineer a novel alveolus bone that could accommodate the full complement of human dentition. This was attempted to liberate a naturally “full” smile from the strictures of skeletal malalignment and so‐called arch length deficiencies. By the year 2023, we were able to develop protocols that achieved that goal and accelerate the rate of tooth movement three to fourfold. In addition, instances of pernicious side effects like apical root resorption and periodontal attachment loss were predictably minimized or nonexistent compared to traditional edgewise therapies. In that regard, our protocols, both surgical and nonsurgical in a phrase, proved to be “faster, safer, and better.” These revelations were brought into high relief by a 20‐year retrospect as attested to by studies cited herein.
Orthodontists’ attempts to enhance the esthetic value of the patients’ lower face are indeed laudable goals. However, the wide‐spread popularity of extraction therapy presents a sobering challenge because it notoriously has been haunted by the unfortunate and unpredictable side effects of premature lower face aging and unsightly flattened (so‐called “dished‐in”) profiles in maturity. Moreover, since these unsightly facial profiles often become most apparent years after active therapy has ended, they are subtle assaults on facial beauty. While evident to the general population, the iatrogenic deformity presents a pattern that is vaguely unsightly but nondescript to laymen. This chapter explains that cell‐ and tissue‐level biology is often ignored in orthodontic curricula and sacrificed by inordinate preoccupations with gross anatomy. But periodontology revels in cell‐level dynamics and affords us, as specialty science integrators, to reveal a universe of new orthodontic science, we call “orthodontic tissue engineering (OTE).”
If dentists claim a desire for “best care,” we must ask how one defines that superlative term. By definition, a superlative is an absolute, and whatever treatment most closely approximates that ideal is reasonably argued as “best.” Is “best care” which is predictable, fastest, with fewest pernicious side effects, least painful, most stable, and most compatible with contemporary cultural values?
This chapter is an attempt to organize a compelling rationale for this new protocol in terms of the underlying cellular dynamics that allow it to achieve case outcome stability superior to the very unstable outcomes that are predictably disappointing in traditional care. Ironically, the new concept of “accelerated orthodontic therapy” was met with political opposition and excessively cynical skepticism by established practitioners. Yet truth prevails and the luddites and clinical nay‐sayers of the 20th century were proven wrong by 21st‐century science. This chapter boldly addressees this controversy as a tribute to intrepid clinicians who preceded us and as a scientific reminder that hard data and scientific epistemological inquiry, however, disruptive to prevailing thought and wishes, will out.
This definition seems sensible to us. Therefore, the aim of this chapter is to describe the ramifications of an emerging perspective and clinical protocol in those terms. Although unheard of by some, the subject is neither new nor novel because it has been evolving over time within the ebb and flow of scientific evolution. It nonetheless brings disruptive issues and protocols that are certainly more predictable, faster, with fewest pernicious side effects, less painful in adjustments, more stable, and more compatible with contemporary cultural values than traditional extraction alternatives. The problem with science is that it has no master. So, it flies in the face of convention and traditional bias.
Late 20th‐century science has delivered a collection of empirical observations and corticotomy protocols that are embodied under the collective rubric, surgically facilitated orthodontic therapy (SFOT) which in this book will be called orthodontically driven osteogenesis (ODO). This term referring to a particular histological reaction, subsumes a number of protocols that are mere variants of the same basic biological phenomena. These terms include but are not limited to “selective alveolar (‐us) decortication” (SAD), decortication without a bone graft, “stem cell orthodontic therapy” (SCOT), “stem cell alveolar therapy” (SCAT), “corticision” when a scalpel is used, “accelerated osteogenic orthodontics” (AOO) where a bone graft is combined with SAD, “periodontal(ly) accelerated osteogenic orthodontics” (PAOO) synonymous with AOO, and here, “orthodontic tissue engineering” (OTE) referring to a 21st century protocol focusing on permanent alveolus bone phenotype alteration. We posit that emerging periodontal sciences, the biology of healing bone, and cell‐level biology, which underlie ODO, are as integral to orthodontics, as civil engineering is to good architectural design. ODO is an example of the clinical science of engineered morphogenetic bone modeling – pioneered by the Russian orthopedist Professor Gavriil Ilizarov – synthesized with traditional orthopedic biomechanics (Figure 1.1). This Russian orthopedic surgeon proved beyond doubt and under great oppression that bone is malleable and can be reshaped to a more physiological form at will. That principle applies to the alveolus bone as well (Figure 1.1).
We pose a challenge to traditional biomechanics to enhance clinical efficacy, ameliorate pernicious side effects, and advance the orthodontic specialty beyond the strictures of simple mechanical art. The issues discussed in this polemic are based on the dual‐certified author’s 50 years of integrating periodontics and orthodontic in an urban private, but academic, practice and 20 years of understanding ODO. It also reflects the combined work of a growing global community of biologists and dentists, formally trained, or passionately interested in reengineering the mass and shape of the foundation of the human dentition. Hence, we write in the first‐person plural, not to imply lock‐step concordance, but rather a general agreement that is compatible with a wide variety of readers. Some repetition will be noticed in this discourse, but that serves as an intentional pedagogical device. The subject matter is quite novel to some readers because we employ a technical prose of molecular biologists, tissue engineers, periodontists, and orthodontists. Moreover, repetition of a new concept within several different contexts can only enrich the conceptualization. Hopefully, the literary device will edify and not distract.
Figure 1.1 This treatment demonstrates what can be done to correct a deformed long bone. The same principle used by Gavriil Ilizarov can be applied to the alveolus bone in correcting dentoalveolar deformities. The leg deformity in (a) represents a deformed bone. (b) The Ilizarov orthopedic device with his surgical protocol can lengthen long bones at the rate of 1 mm/day. (c) Demonstrates an improved esthetic appearance and function. This is what OTE attempts to do with the dental alveolus bone.

Our objective here is not to proselytize but rather to serve examples of what can be achieved by others who wish to minimize extraction therapy side effects. But we hope this is received in a provocative manner to stimulate a meaningful dialectical exchange rather than contentious debate, misinformation, distortions, and misrepresentations that have marred the development of this topic. What is practiced by others is beyond our scope of control. So, we do not call for the immediate condemnation of those who are uncomfortable with protocols presented herein. We focus on scientific advances in ancillary biological fields too fascinating to ignore. And, these innovations can serve as both a beacon and safe harbor for those who are dissatisfied with the limits of the status quo. We are here to show a better path but only for those who wish to embark upon it.
We do not seek to condemn legitimate extraction therapy categorically, but we are intentionally provocative about the perfunctory use of healthy tooth extraction merely for the sake of mindless expediency. We also object philosophically to the excuse of “art” as a refuge from the inarguable demands of science. The fact is that ODO is here to stay, and its use will most likely continue to proliferate worldwide, as any scientific innovation always does. A recent review of the subject published by Hoogeveen et al. (2014) concludes that SFOT “… might effectively shorten the duration of treatment, but careful treatment planning, early activation of appliances, and short intervals between checkups are recommended. SFOT … is not associated with complications such as loss of tooth vitality, periodontal problems, or severe root resorption … prospective research is still needed … ” (Emphasis added).
The lack of prospective, multi‐replicated, double‐blind, placebo‐controlled, multisite, and human clinical studies to which they allude, does not invalidate the ODO innovation. Rather, the lack of such a prospective gold‐standard analysis speaks to the impracticality of such studies, the lack of funding, and the inchoate nature that SFOT shares with many effective clinical disciplines. In this chapter, we elaborate on the necessary items of interest that accord with “careful treatment planning.”
Since the dawn of the orthodontic specialty a philosophical debate has reigned over the intellectual life of most orthodontists: Are we artists or scientists? One reconciliation of this ostensible dichotomy is that art is a goal, and science is the method. The corollary presumption is that an artful outcome via science also represents an optimal physiologic state, e.g., mutually protected occlusion.
Many orthodontists believe that only the most efficient methods of biomechanical loading should define our specialty. To them, periodontal biology is considered an ancillary and often irritating companion. We disagree. We propose that the periodontium is a useful but ignored asset in the creation of optimal function and esthetically harmonious outcomes. These are the axioms upon which we base our posits: Tissue is a collection of cells serving a common function. An organ is a collection of tissues serving a common function. Engineering is the physical manipulation of a natural phenomenon toward a predesigned schema. OTE in the title refers to the burgeoning science of manipulating the dentoalveolar complex and rerouting its architectural development to a predetermined and improved pattern. A plethora of protocols have blossomed over the last two decades and presently constitute a complex collage of techniques. In this proliferation, critical problems of clinical management and intellectual development have arisen that we have solved. These solutions we share.
As a civil engineer can manipulate the course of a river to convert fluid dynamics to electromagnetic potentials, we proffer nothing less vis a vis alveolar bone physiology. We propose that the orthodontist can manipulate the alveolus bone to facilitate orthodontic tooth movement (OTM) and in the process make better bone. The materials of OTE are a collection of surgical and nonsurgical periodontal protocols that are applied to areas of bone beneath a dentition needing orthodontic treatment. The principal method is a collection of selective alveolar decortication (SAD) protocols referred to in the aggregate as “Surgically Facilitated Orthodontic Therapy” (SFOT). For the sake of convenience, in this review, we shall use the acronyms SFOT, OTE, and ODO roughly synonymously, while the latter encompasses more nonsurgical modalities.
Since 1981, this author has attempted to integrate tissue dynamics into the biomechanical procedures of clinical orthodontics. At that time, tissue engineering was just beginning to appear in the biological literature. In retrospect, we see that the manipulative techniques of OTE paralleled similar 21st‐century bioengineering protocols in other fields of the human body from dermatology to consciousness (Nilforoushzadeh et al., 2022).
The popular emergence of SFOT in the early 1990s in the United States brought a promise of sustaining real‐world benefits to patients. Faster care, less infection, and significant reduction of that embarrassing ghost of orthodontics, relapse, are OTE’s most salient merits. In 2006, we were able to organize these new clinical observations with new science in a seminal book chapter published by the Harvard Society for the Advancement of Orthodontics. The title, Tissue Engineering for Orthodontists – a modest first step (Murphy, 2006) foretold this chapter, a modest second step
