Point-counterpoint: Conventional jaw surgery versus the surgery first approach
The title of this paper has been chosen with some care, precisely because it is the format described for most modern debates about surgical timing in orthognathic surgery. Clinicians are either in the conventional (Surgery Late) camp or the Surgery First camp. Being fractured into opposing camps, debaters often resort to adversarial, ad hominem posturing, with no concessions based on facts. Such attitudes are prevalent in the marketplace and in many unreliable professions but have no place in medicine and surgery. (Source: Seminars in Orthodontics)

Insights into Concepts, Protocols, and Evidence of Surgery-First Orthognathic Approach-The journey so far
The aim of this narrative review was to comprehensively describe the surgery-first orthognathic approach (SFOA) or the surgery-first approach (SFA) in terms of the concept, procedure selection and evidence available to date. Comparisons with the conventional orthognathic surgery approach (COSA) are also made. In the light of newer advances in technology, including but not limited, to augmented reality - virtual treatment objective setup, 3D imaging, and computer-aided design and manufacturing (CAD/CAM), the “one patient two problems concept” needs to be thoroughly understood to further enhance both patients’ quality ...

Recent Protocol of the Sendai Surgery-First (SSF) Approach: Clinical and Scientific Perspectives
The treatment protocol of Surgery-First has gradually evolved, since our team employed it for the first time twenty-years ago. In this article, we describe every step of the current Sendai Surgery-First (SSF) approach protocol, in detail. Two major differences between the recent and old protocol, exists, which are (1) In the recent protocol, placement of brackets and passive surgical wires is no longer required before jaw surgery, and (2) only surgical hooks are needed to be bonded to the lateral teeth.

An integrated 3d-driven protocol for surgery first orthognathic approach (sfoa) using virtual surgical planning (vsp)
Appropriate case selection, meticulous planning, and execution are essential to the success of surgery-first orthognathic approach (SFOA). Some of the drawbacks associated with the traditional method of SFOA planning include; inaccurate bite registrations, along with tedious laboratory procedures to generate bite-wafer for transitional occlusion. These limitations can be addressed with the rise of contemporary new-age digital orthodontics encompassing a wide spectrum of technologies, such as, intra-oral scanners, prediction and designing software, 3D printers, and artificial intelligence (AI) guided navigation systems. (So...

Surgery first in cosmetically driven orthognathic surgery
Surgery first is an option in orthognathic surgery that meets the demands of patients with dentofacial deformity looking for an expedited solution to their esthetic concerns. These cosmetically driven patients are also looking to maximize facial esthetics with the surgical procedures. Ancillary surgical procedures such as implants in the malar region, mandibular angle region, and chin are some of the options to enhance the surgical result. Fat grafting and submental lipectomy are also minimally invasive procedures that can add volume in certain areas of the face and reduce in others such as the submental region to achieve ...

Miniscrew driven dentofacial esthetics: A biomechanical approach
The first volume of Seminars in Orthodontics was released in March of 1995 titled “Biomechanics and Appliance Design”.1 Over the past 25 years, the principles of orthodontic biomechanics have not changed much, however, skeletal anchorage has revolutionized the concept of orthodontic treatment for growing and non-growing patients. The appliances, newer materials, and technolog y have doubtless expanded the dimensions of orthodontic care, nonetheless, you must master the fundamentals, such as biomechanics.

Maxillary incisor-based objectives in present-day orthodontics
Orthodontists should be familiar in examining all the components of a smile. A parallel position of the facial aspect of the incisor crown to the face is considered to be the most aesthetic position of the maxillary incisor. A more anterior position of the maxillary central incisors has been shown to be more acceptable than a more posterior position. Exposition of the incisor should not be larger than 3 mm in relationship to the upper lip. The lack of objective criteria to position incisors may be a first step to make the patient become dissatisfied with the treatment result. (Source: Seminars in Orthodontics)

Surgically assisted rapid palatal expansion: is the pterygomaxillary disjunction necessary? A finite element study
Transverse discrepancy is an important factor in determining facial esthetics. It has been shown there is an inverse correlation between the buccal corridor width and the intercanine and intermolar widths. Despite the fact midpalatal expansion is the treatment of choice for growing subjects, for skeletally mature subjects the rapid palatal expansion has limited orthopedic effects, and surgically assisted rapid palatal expansion (SARPE) is preferred. SARPE has shown inconsistencies depending on the surgical technique and/or expander device design. (Source: Seminars in Orthodontics)

Dentofacial Asymmetry: Non-surgical Orthodontic Treatment Using Extra-alveolar Miniscrews
Asymmetric malocclusions have been always a challenge to orthodontists, with different dental, skeletal or dentoskeletal factors being probable causes for the condition. It is key to distinguish between dental and skeletal asymmetry before determining a predictable force system for corrective treatment. The use of mini-implants (MIs) to address anchorage needs in modern orthodontic practice has become an important tool for orthodontists. They have been widely used for anchorage reinforcement purposes and placed in the dentoalveolar region, especially between tooth roots (inter-radicular miniscrews). (Source: Seminars in Orthodontics)
