Efficacy of pure beta tricalcium phosphate graft in dentoalveolar surgery: a retrospective evaluation based on serial radiographic images Maxillofac. Plast. Reconstr. Surg. Pub Date : 2023-07-27 Young-Jin Choi, Hoon-Je Chang, Min Jae Kim, Jee-Ho Lee, Bu-Kyu Lee
The use of beta-tricalcium phosphate (beta-TCP) in dental surgery is limited owing to its rapid absorption compared to mixed formulations of hydroxyapatite. However, newly developed pure beta-TCP crystals have demonstrated slow absorption; hence, they last longer within the defect and act as a scaffold until new bone formation. The oral environment is unique and can prove unfavorable for bone grafts

Mixed reality for extraction of maxillary mesiodens Maxillofac. Plast. Reconstr. Surg. Pub Date : 2023-01-05 Koyama, Yu, Sugahara, Keisuke, Koyachi, Masahide, Tachizawa, Kotaro, Iwasaki, Akira, Wakita, Ichiro, Nishiyama, Akihiro, Matsunaga, Satoru, Katakura, Akira
Mesiodentes are the most common supernumerary teeth. The cause is not fully understood, although proliferations of genetic factors and the dental lamina have been implicated. Mesiodentes can cause delayed or ectopic eruption of permanent incisors, which can further alter occlusion and appearance. Careful attention should be paid to the position and direction of the mesiodentes because of possible damage

Complications from osteoradionecrosis (ORN) and medication-related osteonecrosis of the jaw (MRONJ) include oro-cutaneous fistulas, necrotic bone exposure, soft-tissue defects, and pathologic fractures. The fibula free flap (FFF) is a common free flap method used to reconstruct the mandible in severe cases. Recently, we have used the FFF successfully for the reconstruction of ORN and MRONJ mandibular

Retrospective clinical study of mandible fractures Maxillofac. Plast. Reconstr. Surg. Pub Date : 2022-11-02 Cha, Seungjin, Park, Gaeun, Lee, Baek-Soo, Kwon, Yong-Dae, Choi, Byung-Joon, Lee, Jung-Woo, Jung, Junho, Ohe, Jooyoung
As society becomes more complex, the incidence of mandibular fractures is increasing. This study aimed to analyze the incidence and type and identify etiological factors of mandibular fractures to use them in future treatments. Data were collected from 224 patients who visited the department of oral and maxillofacial surgery at the Kyung Hee Medical Center dental hospital during a 6-year period (2016

Accuracy of digital surgical guides for dental implants Maxillofac. Plast. Reconstr. Surg. Pub Date : 2022-10-25 Kim, Myoung-Ju, Jeong, Jun Young, Ryu, Jaeyoung, Jung, Seunggon, Park, Hong-Ju, Oh, Hee-Kyun, Kook, Min-Suk
Recently developed imaging techniques, such as cone beam computed tomography (CBCT) and CAD/CAM technology, have facilitated reliable implant planning and implant surgical guide production by 3D printing. This study compared the accuracy of implant-guided surgery using the R2GATE® program with CBCT before and after surgery. The study included patients who visited the Department of Oral and Maxillofacial

Therapeutic effects of sialendoscopy for diagnosis and treatment of hyposalivation patients: a retrospective study Maxillofac. Plast. Reconstr. Surg. Pub Date : 2022-10-24 Lee, Seung-Jun, Kim, Euy-Hyun, Lee, Sung-Jae, Chun, Young-Joon, Song, In-Seok, Jun, Sang-Ho
Hyposalivation is disease with multiple symptoms. This disease is hard to be diagnosed and to be treated, and there are not enough clinical protocols to cure the disease. In this study, we propose our own treatment protocols which aim not only to cure the disease but also to care for the disease-related symptoms. At the 1st visit, we collect patient-related information. This procedure includes an intraoral

The management of perioperative pain in craniosynostosis repair: a systematic literature review of the current practices and guidelines for the future Maxillofac. Plast. Reconstr. Surg. Pub Date : 2022-10-14 Mortada, Hatan, AlKhashan, Raghad, Alhindi, Nawaf, AlWaily, Haifa B., Alsadhan, Ghada A., Alrobaiea, Saad, Arab, Khalid
Craniosynostosis is a condition characterized by a premature fusion of one or more cranial sutures. The surgical repair of craniosynostosis causes significant pain for the child. A key focus of craniosynostosis repair is developing effective strategies to manage perioperative pain. This study aimed to review perioperative pain control strategies for craniosynostosis repair systematically. Guidelines

Our problems and observations in 3D facial implant planning Maxillofac. Plast. Reconstr. Surg. Pub Date : 2022-10-12 Saponaro, Gianmarco, Paolantonio, Chiara, Barbera, Giorgio, Foresta, Enrico, Gasparini, Giulio, Moro, Alessandro
Three-dimensional renderings of two-dimensional computed tomography data have allowed for more precise analysis in the craniofacial field. Design, engineering, architecture, and other industries have paved the way for the manipulation and printing of three-dimensional objects. The usual planning is only carried out based on the bony structures, often without taking into consideration the presence of

The comprehensive on-demand 3D bio-printing for composite reconstruction of mandibular defects Maxillofac. Plast. Reconstr. Surg. Pub Date : 2022-10-04 Park, Han Ick, Lee, Jee-Ho, Lee, Sang Jin
The mandible is a functional bio-organ that supports facial structures and helps mastication and speaking. Large mandible defects, generally greater than 6-cm segment loss, may require composite tissue reconstruction such as osteocutaneous-vascularized free flap which has a limitation of additional surgery and a functional morbidity at the donor site. A 3D bio-printing technology is recently developed

Computer-guided buccal cortical plate separation for removal of calcified benign odontogenic tumors affecting the mandibular angle region Maxillofac. Plast. Reconstr. Surg. Pub Date : 2022-09-22 Omara, Mohammed, Gouda, Ayman, Ali, Sherif
Surgical removal of intra-bony calcific benign lesions is technically challenging regarding its accessibility, proximity to vital structures, and deteriorating effect on the remaining bony structures. Computer-guided buccal cortical plate separation was performed for ten patients using patient-specific osteotomy locating guides and pre-bent plates. The guide was designed to outline the osteotomy, the

A rare complication of hemolacria after Le fort I osteotomy: a case presentation Maxillofac. Plast. Reconstr. Surg. Pub Date : 2022-09-17 Helal, May S., Gaber, Ramy M., El-Kassaby, Marwa
Nasolacrimal duct obstruction (NDO) is a common pathology preventing the proper drainage of the tears, and its main symptom is epiphora. Secondary acquired nasolacrimal duct obstruction (SANDO) can be due to a variety of causes including infection, trauma, or neoplasms. It has been reported to occur with different forms of maxillofacial trauma, especially Le Fort II, Le Fort III, naso-orbital-ethmoidal
