Neel Patel, Beomjune Kim, Waleed Zaid, Daniel Spagnoli
This article provides an overview of basic tissue engineering principles as they are applied to vertical ridge defects and reconstructive techniques for these types of deficiencies. Presented are multiple clinical cases ranging from office-based dentoalveolar procedures to the more complex reconstruction of postresection mandibular defects. Several different types of regenerative tissue constructs are presented; either used alone or in combination with traditional reconstructive techniques and procedures, such as maxillary sinus augmentation, Le Fort I osteotomy, and microvascular free tissue transfer...

INTRODUCTION: Arch bars are regularly used in the management of dentoalveolar and minimally displaced fractures of the maxilla or mandible and luxation or avulsion of teeth by maxillofacial surgeons. The procedure for arch bar placement has remained unchanged over the period of years, and this coupled with the difficulty in maintenance of oral hygiene is a problem that begs attention. TECHNIQUE: We have devised a technique to overcome these hurdles and achieve adequate intramaxillary splinting...

Fracture of mandible can be classified according to its anatomical location, in which condylar fracture is the most common one overall and is missed on clinical examination. Due to the unique geometry of the mandible and temporomandibular joint, without treatment the fractures can result in marked pain, dysfunction, and deformity. The condylar fracture may be further classified depending on the sides involved: unilateral/bilateral, depending on the height of fracture: intracapsular (within the head of condyle), extracapsular - head and neck (high condyle fracture), and subcondylar (low condyle fracture), and depending on displacement: nondisplaced, displaced (anteromedially, medially, and lateral), and dislocated...

Increasing experience with alternative timing protocols in orthognathic surgery has given way to new surgical and orthodontic techniques to shorten treatment times, reduce biological costs, and improve the final outcome. A prospective evaluation of class III patients who received an inferior segmental osteotomy (ISO) for decompensation of significantly retroclined lower incisors in the context of 'surgery-first' (SF) or 'surgery-early' (SE) timing protocols was performed. Treatment was planned virtually. A thorough periodontal assessment was performed at baseline and periodically until debonding...

OBJECTIVES: Osteonecrosis of the jaw has been increasing after dentoalveolar surgery in patients treated with an antiresorptive bisphosphonate (BP), especially strong zoledronate (ZA). The pathophysiology underlying why osteonecrosis occurs exclusively in the jaw bone remains unclear. This study investigated skeletal site-specific bone healing during the use of BPs to explore the preferential incidence of osteonecrosis of the jaw bone. STUDY DESIGN: Extraction of mandibular molar and creation of a tibia defect were performed in rats 2 weeks after weekly intravenous injections with the potent ZA and the weaker BP etidronate...

INTRODUCTION: When the mandibular permanent second molar becomes impacted, it is identified as a malocclusion that needs treatment as it often leads to unwanted complications such as caries and periodontitis of the adjacent permanent first molar. Other less common complications include root resorption of the adjacent first molar root or continued root development to be in close proximity to the inferior dental alveolar nerve. MATERIALS AND METHODS: This paper seeks to differentiate various levels of severity of impaction and review treatment options that are considered clinically available for the proper management of the impacted mandibular permanent second molar...

Facial necrotizing fasciitis (NF) is a rare fulminant infection of the soft and connective tissues that spreads along the fascial planes of the face. Its origins most commonly involve odontogenic infection and it is usually associated with a history of dentoalveolar surgery, such as tooth extraction or implant placement. We present a case of ascending facial NF with odontogenic origin in a patient taking a bisphosphonate.
