The correction of skeletal malocclusions in orthodontics has always been a contest for clinicians, especially non-growing individuals, and often necessitates the distalization maxillary or mandibular bases. To accomplish this, diverse treatment modalities have employed by researchers, most recent one is use extra-alveolar bone screws such as Infra-zygomatic Crest (IZC) implants. Unlike conventi...

PURPOSE This clinical study using a specific technique was carried out to determine the clinical effectiveness of zygomatic implants under an immediate loading protocol. MATERIALS AND METHODS All patients treated between May 2000 and October 2006 who received zygomatic implants were included in this retrospective analysis. All patients were treated using the same surgical and restorative prot...

PURPOSE Specifically with zygomatic implants, the bone-to-implant contact (BIC) at the zygomatic bone correlates with the survival of the implant because there is little anchorage at the alveolus. The purpose of this retrospective study was to view and measure the BIC of zygomatic implants in the zygomatic bone. MATERIALS AND METHODS The patients in this study received zygomatic implants at a...

In music performance a basic principle is the marking of phrases, which often seems to be achieved by means of tone durations. In our grammar for music performance the rule PHRASE ARCH, has been formulated to model this eflect. A technical description of the rule is presented. Also presented is an attempt to match the diflerent parameters of this rule to the duration data fiom 28 performances o...

AIM This study aimed to evaluate the length of the holes drilled for the placement of zygomatic implants using two surgical techniques: the original Brånemark and the Exteriorized (extrasinus) protocols. The most frequent implant length used and position where the implants emerged in the zygomatic bone were recorded. MATERIALS AND METHODS Both surgical techniques for inserting zygomatic impla...

In many patients conventional implant treatment cannot be performed in the edentulous maxilla because of extensive bone resorption and the presence of extensive maxillary sinuses, leading to inadequate amounts of bone tissue for anchorage of the implants. The treatment option for these patients has often been some type of bone-augmentation procedure in order to increase the volume of load-beari...
