Impacted Maxillary Canines - Etiology, Diagnosis, Radiologic and Orthodontic Clinical
No full textCanine maxillary teeth are aesthetically most dominant teeth which can present a smile as either holy or evi. They define the mouth’s corner, are involved in the aesthetic smile, maintain occlusal stability, and design the shape of the dental arch. As the position of the impacted canines is amidst vital anatomical structures like the nasal cavity and sinuses in the maxilla and mental nerve in the mandible, a thorough radiographic evaluation to determine the position of the impacted canines is of utmost importance prior to any treatment planning. By using a radiographic image, a clinician can clearly identify its location. The present paper aimed to determine the prevalence, etiology, and clinical diagnosis of impacted maxillary canines in orthodontic patients. Keywords: Canine impaction, Etiology, Inspection, Palpation, Radiographs, CT, CBCT, Transtomograph
Contemporary Aspects of Orthognathic Surgery
No full textU proteklih pet godina ortognatska kirurgija je postala standardni postupak u kirurgiji glave, čeljusti i lica. Temeljen na radovima Obwegesera koji je uveo sagitalnu osteotomiju ramusa ranih 50-tih godina, danas je taj postupak postao zlatni standard u ortognatskoj kirurgiji donje čeljusti diljem svijeta. Uvođenjem naprava za osiguranje centrične pozicije kondila tijekom cijeloga kirurškog postupka Luhr je ranih 80-tih godina dao drugi doprinos modernom razumijevanju cijele funkcionalne rehabilitacije disgnatija.
Premda je LeFort-ova osteotomija uvedena od Wassmunda 20-tih godina, trebalo je sljedećih 50 godina da ta metoda bude prihvaćena u kirurgiji, uglavnom zbog straha od mogućega krvarenja.
Uvođenjem naprave za pozicioniranje kondila za vrijeme osteotomije gornje i donje čeljusti ili kombinirane bimaksilarne osteotomije, kao i upotrebom distrakcijskih naprava, danas smo u mogućnosti rije- πiti i najteže disgnacijske probleme.
U Zavodu za kirurgiju glave, čeljusti i lica Sveučilišta u Würzburgu u zadnja dva desetljeća s više od 2000 ortognatskih kirurških zahvata želimo prikazati razvoj suvremenih kirurških tehnika i kliničke rezultate. Napredak ne bi bio moguć bez primarne i stalne pripreme od strane ortodonta i interdisciplinarno određenih indikacija za kirurško liječenje, ortognatsku obradu pacijenta kao i za postoperativni postupak.
Posebna se pozornost daje ortognatskom liječenju i tehničkim preduvjetima za kirurški postupak.Orthognathic surgery within the past half decade has become a standard procedure in cranio-maxillo- facial surgery. Based upon the elementary works by Obwegeser introducing the sagittal split ramus osteotomy in the early 50is, today this procedure has become the gold standard in mandibular orthognathic procedures worldwide. The introduction of devices to ensure the centric condyle position throughout the entire surgery by Luhr in the early 80ies gives another impact to modern understanding on complete functional rehabilitation after dysgnathia.
Even though the LeFort-I-Osteotomy was already introduced by Wassmund in the 20is it took almost another 50 years before this procedure became accepted in surgery, mainly based on the fear of severe bleeding that may occur during surgery. By introducing a compund condyle positioning device to ensure the exact condyle position throughout both procedures of maxillary and mandibular osteotomy respectively, during combined bimaxillary osteotomies, as well as the targeted use of distraction devices, today we are able to solve even the severest dysgnathia problems.
At the Department of Cranio-Maxillo-Facial Surgery of the University of Würzburg, during the past two decades and far more than 2000 orthognathic surgery cases, we are trying to present a broad overview of the development of the latest surgical techniques and clinical results.
This progress is not possible without the primary and consistent treatment by a specifically skilled orthodontist during primary treatment including the interdisciplinary indication for surgery, the orthognathic preparation of the patient as well as the postoperative treatment.
Therefore special emphasis will be put on the orthognathic treatment, as well as on technical prerequisites for the surgical procedure
RESEARCH AND REVIEWS: JOURNAL OF DENTAL SCIENCES Miniscrews: Clinical Application of Orthodontic
No full textABSTRACT The incorporation of miniscrews into orthodontic treatment planning has allowed for predictable anchorage control and has increased the ability to correct severe skeletal and dental discrepancies. Various minicsrews systems are now available for clinical use and abundant reports and studies are being published, dealing with different aspects of their applications (biology, surgical procedures, placement sites, complications, success rate). The aim of this article is to review the actual considerations regarding their mechanical properties, surgical considerations, risks and complications as well as their success rate and failure reasons

Two Treatment Approaches for Missing Maxillary Lateral Incisors: A Case
No full textAbstract Missing maxillary lateral incisors create an esthetic problem with specific orthodontic and prosthetic considerations. The aim of the present study is to evaluate the clinical success of the transmucosal flapless implant placement and immediate loading of the implants to restore the agenic lateral incisors after completing the orthodontic treatment and during the retention period
