Mundhygiene für Träger festsitzender kieferorthopädischer Apparaturen

1983

Festsitzende kieferorthopadische Apparaturen verursachen besondere Probleme bei der Durchfuhrung der taglichen Mundhygiene. In der vorliegenden Untersuchung wurde durch eine einfache Methode eine Losung dieses Problems beschrieben und deren Effizienz in einer klinischen Untersuchung nachgewiesen.

Extraktionsfolgen unter Kontrolle des Panorama-Röntgenbildes

1968

Die Kontrolle an Rontgen-Panoramabildern von Patienten, bei denen im Rahmen kieferorthopadischer Behandlungen permanente Zahne entfernt worden waren, zeigte folgende Ergebnisse: Abschliesend sei hervorgehoben, das Rontgen-Panoramabilder bei der Entscheidung zur Extraktionstherapie eine wertvolle Hilfe darstellen. Gleichermasen ermoglichen sie eine gute Beurteilung der Zahnachsenrichtung im Seitengebiet wahrend und nach kieferorthopadischen Behandlungen.

Eagle syndrome compared with stylohyoid syndrome: complete ossification of the stylohyoid ligament and joint

2017

A 65-year-old man presented with a history of type 2 diabetes, chronic obstructive pulmonary disease, and non-alcoholic fatty liver. He had had no injuries to, or operations on his neck, but had had right submandibular and retroauricular pain for years. Computed tomography with 3-dimensional reconstruction (Figs. 1 and 2) showed elongation of both styloid processes associated with pseudoarticulation of the hyoid bone on the right side. This confirmed the complete ossification of the stylohyoid ligament, but the patient did not want an operation to resolve it.

Surgically Assisted Rapid Palatal Expansion An Acoustic Rhinometric, Morphometric and Sonographic Investigation

2001

This study aimed to evaluate the effect of surgically assisted rapid palatal expansion on the skeletal structures of the midface. Ten patients (mean age 28.5 years) were investigated by means of acoustic rhinometry, study model analysis and sonography before and after the procedure of surgically assisted rapid palatal expansion. The measurements revealed that surgically assisted rapid palatal expansion not only resulted in transverse expansion of the maxilla, providing dental arch space for lining up the teeth; the procedure also caused a substantial enlargement of the maxillary apical base and of the palatal vault, providing space for the tongue for correct swallowing and thus preventing r…

Marginal bone loss in relation to platform switching implant insertion depth: an update

2011

A review is made, analyzing marginal bone loss in relation to the depth of implant insertion with platform switching, according to the position of the neck (supracrestal, crestal or subcrestal), and evaluating survival of the implants. A PubMed search was made of the studies in animals and humans published between 2005 and 2011, specifying platform insertion depth (supracrestal, crestal or subcrestal) and registering marginal bone loss from the time of prosthetic restoration to the end of follow-up (minimum 6 months). A total of 30 studies were included. The bone loss associated with implants placed at supracrestal level was slightly smaller than in the case of implants placed at subcrestal…

Effect of the lack of primary stability in the survival of dental implants

2018

Background The survival of dental implants has been linked to primary stability. The aim of this study is to analyse the factors that influence the survival of dental implants placed without primary stability. Material and methods A cohort study of implants placed without primary stability was carried out between September 2011 and July 2016. All cases with registered information on the patient and surgical intervention were used. Cases that did not have a 12-month follow-up after implant placement were excluded. Results Out of 2,400 analysed implants, 92 were placed without primary stability. The absence of primary stability was classified as B in 49 cases, C in 38 cases and D in 5 cases. …

Influence of nicotine on machined- and anodized-surface implants. Histometric analysis

2017

Background The nicotine may generate a influence on bone repair and longevity of dental implants. This fact makes studies to improve the surface of the implants are constantly conducted. This study aimed to evaluate the influence of subcutaneous nicotine injection in the osseointegration process on different implant surfaces, through histomorphometric analysis. Material and Methods Therefore, twenty-two male rabbits were randomly distributed into two groups according to the subcutaneous injections: (1) nicotine, 3 mg/day/kg and (2) 0.9% NaCI, 3 mL/day/kg, three times a day. Subgroups were then designated - machined and anodized dental implants were installed in the right and left tibia bone…

Internal oblique line implants in severe mandibular atrophies

2020

Background Maxillary atrophy may be related to mechanical, inflammatory or systemic factors, being a consequence of a reduction in the amount and quality of available bone. Several surgical techniques have been developed for the restoration of bone volume needed for placing dental implants; guided bone regeneration or three-dimensional reconstructions with autologous bone, inter alia, are techniques described in the literature which demonstrate this, all of which preceded by a proper prosthetic surgical assessment. Even when the majority of authors recommend the use of these techniques prior to placing implants, it has been shown that implants with a smaller diameter and length may be place…
